What it is: Spiral galaxy UGC 10043 Where it is: 150 million light-years away in the constellation Serpens When it was shared: December 12, 2024 Why it's so special: This image of a spiral galaxy taken by the Hubble Space Telescope is a portrait more than two decades in the making. Similar to many full-color images of celestial bodies, this one is a composite made from images captured in various wavelengths of light. What distinguishes this particular image is that the data utilized for its creation was gathered during observation sessions in 2000 and 2023, spanning a remarkable 23 years. This long-term advantage of having a space telescope in orbit is evident: Hubble was launched aboard the space shuttle Discovery on April 24, 1990, and its extensive operational duration has allowed it to gather an immense wealth of data about the universe's many facets. But besides the prolonged methods used to create it, it's also an unusual image on its face. Spiral galaxies — which account for about 60% of all galaxies in the universe, according to the European Space Agency — are, by chance, typically seen face-on when viewed from the solar system. That’s why spiral galaxies are typically associated with vivid spiral arms, which can only be seen from a face-on vantage. However, UGC 10043 is viewed edge-on, with its rings seemingly flattened into a line. This unique angle gives astronomers the chance to see how spiral galaxies are structured in 3D. The image of UGC 10043 showcases distinct lanes of dust that would probably resemble spiral arms if the galaxy were viewed from a frontal perspective. In this view, these dust lanes obscure the combined light emitted by the stars that constitute the galaxy. Additionally, they harbor dark clouds that serve as regions for star formation. In the middle of the image lies a luminous bulge — the vibrant core of the galaxy. Every galaxy possesses a core, but the one in UGC 10043 is notably oversized. Researchers believe this may be a result of UGC 10043 merging with a nearby dwarf galaxy, which has provided an abundance of dust and gas, stimulating the formation of new stars. This collision might also account for the slight distortion in the galaxy's disk, which curves upwards on one side and downwards on the other.

A study has revealed that the genetic variations observed in Chornobyl dogs are not a result of mutations.

View pictures in App save up to 80% data. Source: Norman Kleiman Radiation-induced mutation is unlikely to have induced genetic differences between dog populations in Chornobyl City and the nearby Chornobyl Nuclear Power Plant (NPP), according to a new study in PLOS ONE from North Carolina State University and Columbia University Mailman School of Public Health. The study has implications for understanding the effects of environmental contamination on populations over time. "According to Matthew Breen, Oscar J. Fletcher Distinguished Professor of Comparative Oncology Genetics at NC State, 'We have been studying two dog populations that are only 16 kilometers, or roughly 10 miles, apart, yet they exhibit significant genetic differences.'" "We aim to explore whether prolonged low-level exposure to environmental toxins like radiation and lead could account for some of these disparities." Breen serves as the lead author of the research. In earlier research, the team examined genetic variations throughout the genome and pinpointed 391 unique regions in dogs that were distinct between the two populations. Among these regions, several harbored genes linked to the repair of DNA damage. In their latest study, the researchers took a more thorough approach, exploring the dogs' genomes to uncover signs of mutations that might have built up over time. "Initially, we placed the genetic differences between two dog populations into context, revealing that the genetics of dogs from Chornobyl City closely resembled those of dog populations in Russia, Poland, and nearby regions," explains Megan Dillon, a Ph.D. candidate at NC State and the primary author of the research. "This allowed us to utilize the dogs from Chornobyl City as a control group for comparison with the dogs from the nuclear power plant." The research team initially focused on identifying differences at the chromosomal level, subsequently narrowing their investigation to smaller genomic intervals, and finally examining variations at the single nucleotide level. Their goal was to uncover abnormalities and signs of accumulated mutations in germ line DNA—alterations that take place in the DNA of reproductive cells and are inherited from parents to their descendants over generations. "Breen explains, 'It's similar to utilizing the zoom feature on your phone's camera to capture finer details; we begin with a broad perspective of a subject and then focus in closely.'" "It is understood that high levels of radiation exposure can lead to instability starting from the chromosomal level. Although this dog population is over 30 generations separated from the dogs that lived through the 1986 disaster, any mutations that might have provided a survival benefit to those original dogs would likely still be identifiable. However, we did not observe any such evidence in these dogs." Although researchers did not find any evidence of genetic mutation, they emphasize that this does not exclude the possibility that selective pressures may account for the differences observed between the two dog populations. "Dillon explains that, in human context, this situation resembles examining a population that has lived hundreds of years after the disaster occurred." "It’s conceivable that the dogs that lived long enough to reproduce possessed certain genetic traits that enhanced their survival chances. This suggests that there might have been significant selective pressure initially, and subsequently, the dogs at the power plant stayed isolated from the urban population. Exploring this question is a crucial next step that we are currently pursuing." The researchers highlight that these results are just a fragment of the broader context regarding how negative environmental factors can impact the health of both dogs and humans. "While many consider the Chornobyl nuclear disaster to be a localized radiological event in a remote part of Ukraine, the health risks extend far beyond that," explains Norman Kleiman, a co-author and professor of environmental health sciences at Columbia University School of Public Health. "This is attributed to the various other hazardous substances, such as heavy metals, lead dust, pesticides, and asbestos, that were dispersed into the environment during the cleanup and remediation efforts spanning over thirty years." "Although no one currently resides at the NPP or in Pripyat, prior to the Russian invasion, thousands of individuals were still employed there daily, engaged in remediation and construction efforts in the vicinity," Kleiman explains. "Examining companion animals such as these dogs provides insight into the potential health hazards that people may encounter." In addition to looking at the genetics of the dogs, the team also recently identified differences in ticks recovered from the dogs at the power plant and Chornobyl City and the prevalence of the pathogens they transmit. These results, published in the journal Parasites and Vectors, may reflect differential exposures to both ticks and microbes at the two locations. Kleiman emphasized, "The significance of ongoing research into the environmental health implications of major disasters like this cannot be understated. With our societies becoming more technological and industrialized, it is inevitable that we will face similar disasters in the future. We must comprehend the potential health hazards and identify the most effective ways to safeguard individuals." More information: Megan N.

SUPREME-QG: Space-Based Ultra-Precise Assessment of the Equivalence Principle Indicators in Quantum Gravity

How the US-Indian NISAR Satellite Will Provide a Unique Perspective on Our Planet NASA's LEXI is set to offer an X-ray perspective of Earth's magnetosphere. NASA's Parker Solar Probe Achieves Historic Milestone with Closest Approach to the Sun 4分钟阅读 SUPREME-QG: Space-Based Ultra-Precise Measurement of Quantum Gravity's Equivalence Principle Signature View pictures in App save up to 80% data. Artist concept highlighting the novel approach proposed by the 2025 NIAC awarded selection of SUPREME-QG: Space-Based Ultra-Precise Measurement of Quantum Gravity's Equivalence Principle Signature Selim ShahriarNorthwestern University, located in Evanston. Progress in physics has largely been driven by the development and verification of new theories that unify different fundamental forces of nature. For example, Maxwell revolutionized physics with his unified theory of electricity and magnetism, and the Standard Model of particle physics provides a consistent description of all fundamental forces (electromagnetic, strong, and weak) except for gravity. The major barrier to completing the quest for unification is that General Relativity (GR), the current theory of gravity, cannot be reconciled with QM. Theories of Quantum Gravity (TQG), which are yet untested, prescribe modifications of both GR and QM in a manner that makes them consistent with each other. Tests of TQG represent arguably the greatest challenge facing our understanding of the Universe. The most promising way to test TQG is to search for violation of the Equivalence Principle (EP), a fundamental tenet of GR which states that all objects experience the same acceleration in a gravitational field. Violation of EP is characterized by a nonzero Eotvos parameter, Eta, defined as the ratio of the relative acceleration to the mean acceleration experienced by two objects with different inertial masses in a gravitational field. EP violations at the level of Eta < 10^(-18) arise in many versions of TQG (e.g., string theory). The most precise test of the EP to date has been carried out under the space-borne MICROSCOPE experiment employing classical accelerometers, constraining the value of Eta to <1.5×10^(-15). We propose to investigate the use of a radically new method that leverages quantum entanglement to test the EP with extreme precision, at the level of Eta ~ 10^(-20), using a space-borne platform. This method is described in a recent paper by us (PRD 108, 024011, ’23). It makes use of simultaneous Schroedinger Cat (SC) state atom interferometers (AIs) with two isotopes of Rb. Consisting of N=10^6 atoms, the SC state, which is a maximally entangled quantum state generated via spin-squeezing of cold atoms in an optical cavity, acts as a single particle, in a superposition of two collective states, enhancing the sensitivity by a factor of ~root(N)=10^3. Such large-N SC states are difficult to create and have not been observed yet, let alone leveraged for precision metrology. In another recent paper, we described a novel protocol, namely the generalized echo squeezing protocol (GESP), to overcome the challenges of creating such a state (PRA 107, 032610, ’23). We will demonstrate the functionality of this method in a testbed to enable a follow-on space-borne mission capable of testing the EP at the level of Eta ~ 10^(-20). If EP violation is observed, the version of TQG that agrees most closely with the result would form the foundation for a complete theory governing the universe, including its birth: the Big Bang. A null result would force physicists to conceive an entirely new approach to addressing the irreconcilability of GR and QM, fundamentally altering the course of theoretical physics. Either outcome would represent one of the greatest developments in our quest for understanding nature. The SC-state AI (SCAI), also holds the promise of revolutionary improvements in the precision of gravitational cartography and inertial navigation, when configured for simultaneous accelerometry and rotation sensing. The sensitivity of such a sensor, for one second averaging time, would be ~0.9 femto-g for accelerometry, and ~0.5 pico-degree/hour for rotation sensing. This would represent an improvement by a factor of ~10^5 over the best conventional accelerometer, and a factor of ~10^4 over the best conventional gyroscopes. As such, the SCAI would find widespread usage in defense as well as non-defense sectors, including deep-space exploration, for inertial navigation. A space-borne SCAI would be able to carry out gravitational cartography with a resolution far greater than that achieved using the GRACE-FO satellites.

Blue Origin's New Glenn rocket is capable of reaching orbital speeds that are 23 times faster than the speed of sound.

The 320-foot-high rocket will not be launching any satellites throughout the mission. View pictures in App save up to 80% data. Blue Origin's New Glenn rocket is now scheduled for launch on Monday at 1 a.m. ET from Cape Canaveral Space Force Station in Florida. The first launch of the New Glenn has been postponed by 24 hours because of unfavorable weather conditions in the Atlantic Ocean, which was the intended landing area for the New Glenn booster. "Due to ongoing adverse sea state conditions for the booster landing, we are postponing our NG-1 launch by one day, now scheduled for no sooner than January 13. The three-hour launch window remains unchanged, starting Monday at 1 a.m. EST (0600 UTC)," Blue Origin announced on X. Reusable initial phase Earlier, the launch was scheduled for January 10 and then January 12. The New Glenn rocket, which was being developed for almost a decade, has a reusable first stage like SpaceX’s Falcon 9 and Falcon Heavy rockets.The 320-foot-high rocket will not be launching any satellites throughout the mission. However, it’s carrying a payload, which is a test version of Blue Origin’s new “Blue Ring” spacecraft platform. The company will make efforts to recover the rocket’s first stage on Monday morning as the booster lands in the Atlantic Ocean on its Landing Platform Vessel 1. Called Jacklyn, the barge is nicknamed after the mother of Jeff Bezos, who is the founder of Blue Origin. Capturing the booster. The payload for this mission is the Blue Ring Pathfinder. This spacecraft will test Blue Ring’s core flight, ground systems, and operational capabilities as part of the Defense Innovation Unit’s (DIU) Orbital Logistics prototype effort.   “Our key objective is to reach orbit safely. We know landing the booster on our first try offshore in the Atlantic is ambitious—but we’re going for it,” said the company in a statement. Jarrett Jones, Senior Vice President of New Glenn, emphasized that this marks the inaugural flight of New Glenn, and the team has engaged in extensive preparations leading up to this moment. The procedure “However, no level of ground testing or mission rehearsals can truly substitute for the experience of flying this rocket. The moment has come to take to the skies. Regardless of the outcome, we will gain insights, improve, and utilize that knowledge for our upcoming launch,” Jones stated. “This marks our inaugural flight, and we have put in extensive preparation,” stated Jarrett Jones, Senior Vice President of New Glenn. “However, nothing can substitute for the experience of actually flying this rocket, despite all the ground tests and mission simulations we’ve conducted. The moment has come to take to the skies. Regardless of the outcome, we will gain insights, make improvements, and use that information for our upcoming launch.” During the launch, after burning through most of its fuel, the booster will detach from the upper portion of the rocket, which includes the vehicle’s nose cone, or payload fairing, that’s designed to shield cargo during liftoff. The booster will then use fins and strakes — or winglike attachments that flare out from its top and base, respectively — to help guide itself toward its landing target, a seafaring recovery platform, reported CNN. Ignition test In late December 2024, New Glenn achieved a significant milestone by successfully conducting an integrated launch vehicle hotfire test, marking the last major step before its inaugural flight. The NG-1 mission is set to transport a Blue Ring Pathfinder as its initial payload. The seven-engine hotfire lasted 24 seconds and marked the first time Blue Origin operated the entire flight vehicle as an integrated system. The multi-day test campaign leading up to the hotfire included numerous inert functional and tanking tests. The integrated launch vehicle included the first and second stages of the NG-1 flight vehicle, and a payload test article comprised of manufacturing test demonstrator fairings, a high-capacity fixed adapter flight unit, and a 45,000 lb payload mass simulator.  According to Blue Origin, the official NG-1 Wet Dress Rehearsal showcased the ultimate launch protocols that precede the hotfire engine test. “All seven engines performed nominally including at 100% thrust for 13 seconds. The test also demonstrated New Glenn’s autogenous pressurization system, which self-generates gases to pressurize GS1’s propellant tanks,” said the company in a statement. Reports revealed that New Glenn’s two engines, optimized to function in the vacuum of space, should fire up and propel the vehicle to speeds necessary to enter orbit — typically around 17,500 miles per hour, or nearly 23 times the speed of sound.

Progressive Views May Clash with This Scientific Research

Throughout the pandemic, the slogan "trust the science" gained significant traction. The underlying reality of that phrase was that we were expected to rely on the 'science' endorsed by federal agencies to validate their decisions. This often meant sidelining qualified experts who opposed the scientific assertions being made. This mindset has since permeated other areas of society, particularly concerning issues like gender identity and sexual orientation. I recently viewed a video featuring Erica Komisar, a psychoanalyst, author, and parenting coach, where she talked about a research study carried out in the United Kingdom. The researchers were intrigued by the differing responses of men and women in specific scenarios. To explore this, they examined various parents and analyzed how both mothers and fathers reacted to a range of stimuli. For instance, if a baby starts crying during the night, the mother will instinctively jump out of bed to attend to the child, while the father usually remains asleep. Conversely, if an unusual sound is heard from outside the home, it's the father who will quickly take action. Researchers discovered that specific hormones influence this behavior. Men possess elevated levels of vasopressin, which enhances their protective instincts. This hormone activates an instinctual reaction to external stimuli. In the case of a crying baby, the study's authors explain that both parents can distinguish between a cry of discomfort and one of fear. When the baby cries out of discomfort, the mother's nurturing instinct takes over, prompting her to respond, while the father may attempt to return to sleep. However, if the cry signifies fear, the father's instinct kicks in, and he instinctively rushes to the baby's aid. This research has reaffirmed findings that have previously been established. However, many individuals take issue with this study because it does not align with their emotional responses to the biological distinctions between males and females. They tend to interpret the findings as a moral judgment, suggesting that a woman cannot be a protector of her family or that a man cannot be a caregiver. In doing so, they are making assumptions that were not intended by the research. The study simply indicates that there are scientific explanations for the typical differences in how the two genders respond to external stimuli. It's important to recognize that individuals respond differently, as we are all unique. Some men may possess higher levels of the hormone associated with protective instincts, while others may have lower levels. This variability applies to women as well. A fundamental reality of both life and science is that exceptions exist to nearly every generalization. Those who disagree with scientific findings often seize upon these exceptions to challenge the established facts. Unfortunately, this mindset has been embraced by many, who use it as a means to elevate their own sense of self-worth or moral superiority over others. The outcome of this situation is that we have witnessed several generations of young individuals who are lost in understanding their identity. They find themselves in a state of confusion and conflict, grappling with emotions that are inherently human but have been labeled as products of toxic masculinity. This undermines foundational values. How often have we heard that individuals are born with certain traits and should be free to express themselves accordingly? Yet, when a young man displays typical masculine behavior, he is labeled as toxic, despite these traits being part of his nature. He is pressured to suppress his instincts. Is it any surprise that we are seeing an increase in mental health issues among the youth?

UK develops innovative radiation-resistant steel, marking a significant advancement for fusion energy startups.

To create a miniature Sun on Earth, you'll require a significant amount of robust metal — and plenty of it. View pictures in App save up to 80% data. Scientists in the UK have forged 5.5 tonnes of a new kind of steel capable of withstanding the searing heat and intense neutron radiation of nuclear fusion, the same reaction that powers the Sun and stars. The breakthrough is another boost to Europe’s growing flock of fusion energy startups. A working group known as NEURONE, part of the UK Atomic Energy Authority (UKAEA), has successfully developed reduced-activation ferritic-martensitic steel, commonly referred to as "RAFM." This achievement represents the first instance of RAFM being manufactured on an industrial scale within the UK. “This is really positive and potentially has relevance for all fusionenergy projects,” Ryan Ramsey, COO at British startup First Light Fusion, told TNW.    Fusion reactors heat hydrogen atoms to very high temperatures, creating a charged state of matter known as plasma. By employing magnetic fields or lasers to compress this plasma, they induce the fusion of atoms, resulting in the release of vast amounts of energy that can be harnessed for electricity generation.  In a fusion energy reactor, the plasma can soar to astonishing temperatures of 150 million°C, momentarily turning these machines into the hottest locations in our solar system. To prevent the plasma from touching the metal walls, massive magnets are employed to keep it suspended in the air. The walls themselves are cooled to prevent them from becoming too hot, but standard steel simply cannot withstand the extreme conditions.  Ramsey stated, “The primary issue isn't the heat itself, but rather the damage caused by neutrons.” Neutron radiation can rapidly compromise the inner structures of a nuclear reactor. "If you can't handle that, you'll find yourself frequently shutting down the fusion reactor to replace the walls, which results in a loss of power generation during those periods," he clarified.    View pictures in App save up to 80% data. The internal surfaces of fusion reactors, such as the decommissioned JET tokamak shown in this image, are required to endure extreme temperatures and high levels of radiation. Photo credit: EUROfusion. NEURONE has developed a new type of steel that can endure significant neutron exposure and temperatures reaching as high as 650°C, which could enhance the operational efficiency of upcoming fusion power plants.  For startups such as Oxford University spinout First Light, this development represents a significant advancement towards the ambitious objective of creating a commercially viable fusion reactor.   NEURONE utilized an electric arc furnace to forge the steel, relying on electricity rather than coal, located at the Materials Processing Institute (MPI) in Middlesbrough. According to UKAEA, this innovative forging technique could reduce the cost of producing RAFM by as much as 10 times compared to previous methods.  David Bowden, the leader of the NEURONE programme, stated, “Producing 5.5 tonnes of fusion-grade RAFM steel establishes a strong basis for the affordable manufacturing of this type of fusion steel in future commercial fusion initiatives.”   Despite huge progress, fusion energy has always seemed to be that “20-years-away” technology. But the tides might be changing. According to a poll at the International Atomic Energy Agency’s (IAEA) forum in London last year, 65% of industry insiders think fusion will generate electricity for the grid at a viable cost by 2035, and 90% by 2040.

'Siberian Express' Set to Intensify January's Frigid Conditions in Central and Eastern Regions

View pictures in App save up to 80% data. January has delivered a bitterly cold experience for numerous residents in the central and eastern regions, and the arrival of the "Siberian Express" is set to intensify the icy conditions as we approach the weekend and the upcoming week. First up, a temperature roller coaster this week. A bout of arctic air currently entrenched over the Midwest and Northern and Central Plains will sweep toward the Northeast through Wednesday. Low temperatures will sometimes be 10 to 25 degrees below average into midweek. Following this event, the Plains and Midwest are expected to experience significant warming, with temperatures reaching 10 to 20 degrees above the seasonal norm by Thursday and Friday. This will result in afternoon highs climbing into the relatively mild (for January) range of the 30s and 40s across many regions. View pictures in App save up to 80% data. Present Temperature Readings The "Siberian Express" arrives this weekend. When arctic air spills into the U.S. during winter it can have one of multiple source regions. That includes Arctic Canada, Alaska, and in the case what lies ahead this weekend and early next week, Russia's Siberia region. Sometimes meteorologists call this the "Siberian Express" because of the cold air's geographic origins. Siberia ranks among the coldest places on the planet. For instance, several areas in the region recorded temperatures plunging close to minus 60 degrees Fahrenheit in the 24-hour period leading up to Monday morning in the U.S. Such extreme cold is a common occurrence during the winter months in Siberia. Considering the frigid origins, arctic air from this area can deliver a powerful impact as it moves southward into Canada and the United States. View pictures in App save up to 80% data. How frigid temperatures might become. In general, some locations might see their coldest lows of winter so far, while for others it might rival what they have already seen. Minneapolis may experience its first double-digit below-zero temperature of the season early next week. Chicago and Denver could experience their initial sub-zero temperatures of the season. Please remember that this forecast is several days out, so the low temperatures for Sunday through next Tuesday may change. We will provide more updates on the forecast later this week. Another undeniable fact is that wind chills will once again pose a threat to many starting early next week. View pictures in App save up to 80% data. Next Week's Predicted Morning Lows January's cold start is notable for one reason. Record-setting cold hasn't been widespread this month, but what we've seen so far plus what's to come makes it noteworthy from a persistence point of view. For the first 11 days of the month, temperatures in many regions east of the Rockies were generally below the average, according to NOAA's analysis. Particularly significant was the observation that areas in the Plains, South, Ohio Valley, and mid-Atlantic experienced temperature drops of 5 degrees or more below the norm. Aside from a short warm spell towards the end of this week, most of these regions will still experience the harsh effects of this chilly January trend as we move into the final days of the month.

Recent studies shed light on the evolutionary reasons behind the development of saber-toothed predators' formidable teeth.

View pictures in App save up to 80% data. Saber-toothed tiger (Shutterstock) Saber teeth – the long, sharp, blade-like canines found in extinct predators such as Smilodon – represent one of the most extreme dental adaptations in nature. They evolved at least five times throughout mammalian history and are a classic example of convergence, which is when similar structures evolve independently in unrelated animal groups. With no living representatives, scientists have long debated how these predators used their fearsome teeth, and why this extreme tooth shape evolved so often. Our new study, published today in Current Biology, provides an answer. We found extreme sabre teeth are functionally optimal, meaning their shape provided a real advantage as specialized weapons. Their slender and sharp forms were perfect for puncturing prey. However, this came at a cost: sabre teeth were also weaker and more prone to breaking. These discoveries hold significant value as they enhance our comprehension of the evolution of extreme adaptations in the natural world. Additionally, they provide valuable perspectives on optimal design principles that can be applied not only in biology but also in the fields of engineering and technology. Saber-toothed hunters throughout history Saber-toothed predators once inhabited various ecosystems worldwide. Fossil evidence of these creatures has been discovered across North America, Europe, Africa, and Asia. What sets them apart are their sabre-like teeth, a unique form of canine tooth. These teeth are elongated, pointed, flattened on the sides, and exhibit a curved shape. This contrasts with the shorter, sturdier, conical canines found in contemporary large felines like lions and tigers. View pictures in App save up to 80% data. Numerous extinct predators globally developed saber-shaped teeth that significantly differ from the teeth of today's large felines. Tahlia Pollock This legendary tooth predates the dinosaurs, having emerged approximately 265 million years ago among a category of mammal-like reptiles known as gorgonopsids. Over millions of years, saber teeth evolved repeatedly in different groups of carnivorous mammals, marsupial relatives like Thylacosmilus and “false” saber-tooth cats such as Barborofelis. The most well known saber-toothed predator is Smilodon. It persisted until just 10,000 years ago. You can look at a 3D model of one of these predators – Smilodon fatalis – below. This model has been digitised from a cast specimen from the Natural History Museum of Los Angeles County. Extensive studies of saber-tooth ecology have led to a widely accepted conclusion that these formidable predators mainly hunted large animals. They employed powerful neck muscles to execute slashing attacks aimed at the soft tissues of their prey's throat. It is believed that their specialized teeth provided a significant advantage in this regard, enabling them to effectively deliver a lethal bite. This concept is what we aimed to explore. Evaluating the balance between puncture resistance and strength In particular, we examined whether their shape achieved an ideal compromise between two opposing requirements concerning tooth functionality. On one hand, the teeth needed to be sharp and slender to effectively penetrate prey. On the other hand, they had to be sturdy and resilient to avoid damage or breakage. In order to explore this topic, we performed an extensive analysis involving over 200 various carnivore teeth, which encompassed both extinct saber-toothed species and contemporary animals. Initially, we assessed the three-dimensional structure of their teeth to compare saber teeth with those of other carnivorous species. Subsequently, we conducted two experiments to evaluate the biting performance of a selected group of these teeth. We created tooth models using stainless steel and inserted them into a gelatin block (which mimicked prey flesh) to assess the force required for puncturing. By utilizing metal replicas, we avoided any bending of the teeth throughout the experiment, thus guaranteeing precise measurements of the puncture force. We conducted engineering simulations to evaluate the stress levels experienced by various tooth shapes when subjected to biting forces. This analysis helped us understand their potential for fracturing. Ultimately, we performed an "optimality" assessment to identify which dental shapes provided the most effective combination of puncture efficiency and durability. A saber-toothed model created through 3D printing is being thrust into a gelatin block to assess the amount of force required for penetration. The most advanced forms of saber-tooth are the most efficient. Our findings regarding the shape of saber-toothed cats call into question the conventional classification of these predators into only two groups: the dirk-toothed, characterized by their elongated and slender form, and the scimitar-toothed, known for their shorter and laterally flattened appearance. Instead, we uncovered a continuum of saber-tooth shapes. This ranged from extreme forms, such as the long, curved canines of Barbourofelis, Smilodon and Hopolophoneus, to less extreme forms, such as the straighter, more robust teeth of Dinofelis and Nimravus. Our results reveal that the extreme saber-toothed forms, like Smilodon, were optimised for puncturing prey with minimal force. However, they were more prone to breakage under high stress. Less extreme saber-toothed forms, such as Dinofelis, were also optimal but in a different way. They struck a more balanced trade-off between puncture efficiency and strength. The existence of different saber-toothed species that developed distinct balances between puncture effectiveness and structural strength indicates a wider array of hunting tactics than was previously recognized. This finding aligns with an expanding collection of studies regarding their ecological variety. View pictures in App save up to 80% data. Morphospace’ (visualization of shape diversity) of sabre and non-saber-tooth canines showing areas of optimal performance. Miranta Kouvari & Melisa Morales/Science Graphic Design An eye-catching remedy These findings shed light on the repeated evolution of extreme sabre teeth, likely influenced by natural selection favoring an ideal design. Additionally, they may offer insights into the reasons behind their eventual extinction. Their growing specialization might have functioned as an "evolutionary ratchet," enhancing their efficiency as hunters while simultaneously rendering them more susceptible to extinction when environmental shifts occurred and their food sources dwindled. Our research offers valuable perspectives on the evolution of extreme adaptations in various species. By combining biomechanics with evolutionary principles, we gain a clearer understanding of how natural selection influences organisms to excel in specific functions. The sabre-toothed design showcases an impressive approach to a core mechanical problem, achieving a balance between effectiveness and durability — a principle that is similarly seen in tools created by humans. The balance between sharpness and durability is a crucial factor in engineering, impacting the design of a wide range of tools, including surgical scalpels and industrial cutting blades. Engineers creating precision instruments like hypodermic needles or advanced cutting tools can draw inspiration from nature's evolutionary designs, utilizing the same principles that influenced the development of these ancient predators.

Curious About the Pre-Mating Habits of Whale Sharks? Neither Did I, But Researchers Were Intrigued and Captured It on Film!

I like to think of myself as the inquisitive type, but even I wasn't curious enough to wonder how whale sharks get it on. But some scientists did and now we've got video of what they do beforehand. I hadn't noticed until now, but the courtship rituals of whale sharks have remained one of the intriguing enigmas in the realm of sharks. I'm not entirely sure why this is the case. I assumed they would engage in similar behaviors as other shark species, just on a larger scale. Fortunately, we've got scientists who wanted to know the answer, and they weren't willing to wait for a Shark Week documentary fore the details, they had to do the dirty work. According to Phys.org, some scientists have been hanging around Ningaloo Reef off the coast of Australia which, from the sounds of it, is like the Whale Shark world's Studio 54. All the breakthroughs in the steaming hot world of whale shark sex are coming out of Ningaloo Reef. During a recent expedition, researchers observed what they thought was a male whale shark attempting to impress a female. However, rather than allowing him some privacy to charm her, they began filming the scene, with one eager scientist swimming right alongside him, inadvertently interrupting his efforts. It's difficult to discern the situation clearly, but researchers have provided a concise summary for our understanding. "The male shark was seen opening its mouth and lunging toward the female's caudal fin. It accelerated its swimming and lunged once more at her tail, managing to make contact and briefly biting it," the researchers noted. "In response, the female quickly pivoted, with her pectoral fins angled downwards to confront the male." Wow... Whale sharks are truly fascinating creatures! "Following a short halt in their progression, the female swiftly pivoted once more, resulting in contact between the male's snout and her caudal fin. Subsequently, the female plunged quickly to a greater depth, with the male in tow. At this juncture, the researchers were unable to observe the sharks from the surface." Check it out. Deal done. That guy likely whisked her away to his whale shark-themed place and cranked up some Barry White tunes.  In about nine months, or however long it takes for whale sharks to gestate, a new little whale shark will make its debut — likely measuring around the size of a Buick — and eventually, it will be gliding through Ningaloo Reef in search of a partner.

Quadrantid Meteor Shower: A Guide to Viewing the Spectacular Event in UK Skies Tonight

NASA has labeled the Quadrantids meteor shower, originating from the 2003 EH1 asteroid, as the most impressive meteor display of the year. It remains observable for another two days in areas of the UK with minimal light pollution. View pictures in App save up to 80% data. The Quadrantids meteor shower can be seen in the skies over the UK tonight, but it will only last for the next 48 hours. The best meteor shower of the year will light up UK skies tonight as Brits have another 48 hours to catch a glimpse. The Quadrantids shower is known for its frequent fireballs and is considered by NASA one of the most impressive throughout the year. And while its intensity peaked Friday last week, stargazers still have another two days to see the show before they return. Those lucky to see the shower so far got to se up to 50 meteors an hour. The Quadrantids, unlike most meteor showers which come from comets, originate from an asteroid called 2003 EH1. Beginning on Boxing Day, their peak was on Friday and Saturday last week, but they will remain visible in UK skies until Sunday. And while fancy stargazing telescopes aren't needed for catching sight, Brits have a much better chance of glimpsing them from what's known as a dark sky area. These are areas with minimal light pollution, which obscures light particles from stars, mean far more is visible. The UK has several designated 'dark sky' areas, although any remote location far away from cities and towns would still be better. While the shower has been seen over London, this was through multiple exposures from advanced camera lenses rather than the naked eye. View pictures in App save up to 80% data. On a clear night, April 22, 2020, the London Millennium Footbridge sparkles under a canopy of stars. Official dark sky areas include Moore's Reserve in the South Downs, West Penwith in Cornwall, Cranborne Chase in Dorset, Exmoor National Park, the Yorkshire Dales and North York Moors, Northumberland and Tomintoul and Glenlivet in the Cairngorms. Eryri National Park (Snowdonia) and Gower National Landscape in Wales are also dark sky areas. It is advisable to allow your eyes approximately 15 minutes to adapt to the lighting conditions before spotting the meteor showers, which will be visible about two-thirds of the way up from the horizon, where the atmosphere is less dense. The origin point for the Quadrantids is located in the now-defunct constellation of Quadrans Muralis, which is the source of its name, and it is situated near the Plough, also known as the Big Dipper, in the sky. View pictures in App save up to 80% data. The map highlights regions in the UK that experience the highest and lowest levels of light pollution, which significantly impacts stargazing opportunities. The Royal Museum of Greenwich stated: "The Quadrantid meteor shower is one of the most powerful and reliable meteor showers annually, reaching a peak rate of 120 meteors per hour during clear nights. These meteors are fragments of debris that enter Earth's atmosphere at velocities reaching 70 kilometers per second, disintegrating and producing the luminous trails we refer to as meteors." "The Quadrantids are recognized for their brief but intense peak that occurs over a span of just a few hours. These meteors seem to originate from the constellation Boötes, close to the Big Dipper. In 2004, astronomer Peter Jenniskens proposed that the source of the Quadrantids might be the minor planet designated as 2003 EH1."

The inaugural map of the Earth's vanished continent has been released.

View pictures in App save up to 80% data. The initial map of Earth's vanished continent has been released. You may believe you're familiar with all the continents, but have you heard of Zealandia? In 2017, a previously unknown contingent of the shores of New Zealand was discovered - making headlines globally. Zealandia, known as Te Riu-a-Māui in the Māori language, covers more than 5 million square kilometres, making it twice the size of the subcontinent of India. You might be asking yourself why it wasn't uncovered earlier. The explanation lies in the fact that 95 percent of its landmass is hidden beneath the southwest Pacific Ocean, having vanished long before the arrival of humans on the planet. What remains above water are primarily a significant mountain range (the two islands of New Zealand) along with a few smaller oceanic islands. Not much information is available about the newly found continent, primarily because it is largely unreachable. Nevertheless, a group of geologists from various parts of the globe has created a fresh geological map that includes Zealandia. This map was developed through a blend of rock samples collected from the ocean and geophysical mapping techniques. As geologists explored the outer edges of Zealandia in search of samples, they uncovered significant sandstone formations along with deposits of basaltic rock pebbles. The sandstones are estimated to be approximately 95 million years old and include older granite and volcanic pebbles. This indicates that when Zealandia was above water, rivers originating from volcanic highlands deposited materials into tectonic basins. The highlands were once a bustling volcanic range around 30 to 50 million years ago, but they probably underwent significant erosion during the time when the sandstone was laid down. Geologists theorize that Zealandia experienced a gradual submersion approximately 40 million years ago, a conclusion supported by the finding of basalt pebbles linked to underwater volcanic activity. The study "Reconnaissance basement geology and tectonics of North Zealandia" was published in the journal Tectonics(2023).

Cuttlefish Are Capable of Passing the Marshmallow Test Designed for Children

View pictures in App save up to 80% data. (Image credit: Steve De Neef/VW Pics/Universal Images Group, courtesy of Getty Images) Cuttlefish are smart. Like, human-level smart. While they’re not quite on par with an adult human with a college degree, studies show that the common cuttlefish can delay gratification, a trait found in creatures we commonly consider intelligent, like primates, corvids, some dog breeds, and humans. A 2021 study tested the cognitive abilities of cuttlefish with a modified version of the famous Stanford marshmallow experiment. The cuttlefish were divided into tanks with two types of food — a delectable live shrimp and a less delectable raw dead prawn. Content created by VICE A door marked with a circle swung open without delay, exposing the prawn inside. In contrast, the door adorned with a triangle would take anywhere from 10 to 130 seconds to open, ultimately disclosing the live shrimp. The final door, featuring a square, remained perpetually shut. The researchers discovered that cuttlefish exhibited a strong preference for live shrimp, often opting to forgo the immediate availability of dead prawns. They were willing to wait as long as necessary for the triangle door to open, allowing them to access the live shrimp instead. The cuttlefish recognized that the live shrimp was the tastier and more appealing option, so it decided to bide its time until its favorite treat was within reach. Different species exhibit the ability to postpone gratification for reasons that are often more intricate than those of the cuttlefish, such as the practice of saving food for future use. In its natural environment, the cuttlefish faces threats from predators while foraging, which might explain its more selective behavior, as it waits for the perfect opportunity to secure food. “Cuttlefish spend most of their time camouflaging, sitting and waiting, punctuated by brief periods of foraging,” lead author Alexandra Schnell said in a press release. "When they search for food, they lose their camouflage, making them vulnerable to any ocean predator looking to catch them. We hypothesize that the ability to delay gratification may have developed as a consequence of this behavior, allowing cuttlefish to enhance their foraging strategy by waiting for higher quality food options."

How to observe the rare comet that will be visible from Earth this month

If it's not to your liking, you can always choose to wait an additional 160,000 years. View pictures in App save up to 80% data. The universe is brimming with intriguing celestial objects and various marvels, and you could have the chance to witness one in just a few days. If, for some reason, you don’t know the names of every rock moving through the infinite vacuum of space, then you might have missed the upcoming news. Comet G3 ATLAS (C/2024) is on its way, and you could have the chance to see it! Don’t worry if the name doesn’t sound familiar; it was just discovered not long ago. It was discovered in early April 2024 and was the third comet found that month and identified by the facility Asteroid Terrestrial-impact Last Alert System (ATLAS), according to PEOPLE. As for where it came from, Space.com reports that it's believed to have originated from Oort Cloud, which is comprised of millions of tiny icy objects estimated to be 10 trillion miles from the Sun. Nevertheless, astronomers suggest that spotting it in the night sky could be more challenging than one might think. View pictures in App save up to 80% data. The comet is anticipated to shine more brightly than Venus (Getty Stock Image) On January 13, the comet is anticipated to reach its perihelion, signifying that it will be at its nearest position to the Sun. At this time, the comet will come within approximately 8.3 million miles of the Sun. The same day, it's also predicted to reach its closest point to Earth. This time around, many more people can catch a glimpse of it in the clear sky using rather basic technology, binoculars or a telescope - and if visible, it'll look like a bright star with a white or golden color, Space.com says. Although both the Northern and Southern hemispheres will have opportunities to see it, those in the Southern hemisphere will find it easier to catch a glimpse. According to the Sky and Telescope Organization, skywatchers in the Northern Hemisphere might have the ability to spot the comet 'extremely low in the southwestern sky' from about January 15 to 18. The Planetary Society reports that while some experts anticipate the comet may disintegrate as it approaches the Sun, recent studies suggest that Comet G3 has experienced similar encounters before. View pictures in App save up to 80% data. With fairly simple technology, you should be able to identify it (Getty Stock Image) Data indicates that it is estimated to follow an orbit of roughly 160,000 years, suggesting it has undertaken an extraordinary journey. This challenging orbit suggests that the comet has probably endured at least one close encounter with the Sun in the past. While it's tough to predict a comet's visibility, Forbes reports that the comet is said to be shining at -4.5 magnitude, which is brighter than Venus. Although some may view this as a negative indication, comet observer John Bortle shared with Space.com that there have been reports of 'unusual' characteristics, including a 'shadow of the nucleus', which typically does not indicate any disruption. Bortle remarked, "I believe the odds of it surviving are roughly equal, around 50:50." It's definitely worth a try.

A Restful Night's Sleep Refreshes the Mind Similar to How a Dishwasher Cleans Dishes – Yet Caution is Advised with Sleep Medications.

View pictures in App save up to 80% data. Acknowledgment: Nadia Alzoubi and Natalie Hauglund Recent studies indicate that a restful night's sleep can refresh your mind, much like starting a dishwasher before sleeping and waking up to find everything tidy and organized in your thoughts. A team of scientists from around the world explains the process as a method of clearing out the waste that accumulates in the brain while we are awake. Their research also sheds light on how sleeping medications might interfere with the brain's "brainwashing" mechanisms, which could have lasting impacts on cognitive abilities. Scientists have discovered that the brain features an inherent waste clearance mechanism known as the 'glymphatic system.' This system facilitates the circulation of fluid within the brain and spinal cord to help eliminate waste. This process aids in eliminating harmful proteins that create sticky plaques associated with neurological conditions like Alzheimer's disease; however, the underlying mechanisms that propel this system have been elusive until recently. Researchers at the University of Copenhagen in Denmark discovered that a molecule known as norepinephrine is crucial for the brain's cleansing process in mice. In the deep stages of sleep, the brainstem emits small bursts of norepinephrine approximately every 50 seconds. The lead researcher of the study, Professor Maiken Nedergaard from the University of Rochester in New York, elucidated that norepinephrine causes blood vessels to constrict, producing slow pulsations that establish a rhythmic movement in the adjacent fluid, facilitating the removal of waste. She remarked, “It’s similar to starting the dishwasher before heading to sleep and waking up to a refreshed mind.” "We're fundamentally exploring the factors that influence this mechanism and aiming to characterize restorative sleep through the lens of glymphatic clearance." In their quest for clues, she and her team investigated the effects of sleep on mice brains. Their primary focus was on the connection between norepinephrine levels and blood circulation during deep sleep phases. Researchers discovered that fluctuations in norepinephrine levels are linked to changes in brain blood volume, indicating that norepinephrine may initiate a rhythmic pulsation within the blood vessels. The researchers subsequently analyzed the relationship between variations in blood volume and the flow of fluid within the brain, discovering that fluctuations in brain fluid flow align with changes in blood volume. The blood vessels function as pumps, driving the adjacent brain fluid to remove waste materials. "Think of norepinephrine as the conductor of an orchestra," said Dr. Natalie Hauglund, the lead author of the study from the University of Copenhagen and the University of Oxford. "The rhythmic contraction and expansion of the arteries create a balance that propels the cerebro-spinal fluid through the brain, effectively eliminating waste materials." Dr. Hauglund subsequently inquired whether all types of sleep were essentially the same. In order to investigate, the research team administered zolpidem, a widely used sleep aid, to mice. Researchers discovered that the norepinephrine levels during deep sleep were reduced by 50% in mice treated with zolpidem compared to those sleeping naturally. While the zolpidem-treated mice did fall asleep more quickly, there was a significant decrease of over 30% in fluid transport into the brain. The researchers say their findings published in the journal Cell show that the sleeping pills likely disrupt the norepinephrine-driven waste clearance during sleep—and the findings probably apply to humans, as well, because also have a glymphatic system. Researchers have detected comparable patterns of norepinephrine waves, blood circulation, and cerebrospinal fluid movement in humans. “More and more people are using sleep medication, and it’s really important to know if that’s healthy sleep,” said Hauglund in a media release. “If people aren’t getting the full benefits of sleep, they should be aware of that, so they can make informed decisions.” Their research might also shed light on the ways in which inadequate sleep could play a role in the development of neurological conditions like Alzheimer’s. "With our understanding that norepinephrine plays a key role in the brain's cleansing process, we may be able to discover ways to promote longer and more restorative sleep for individuals," Professor Nedergaard concluded.

A rocket needs to reach a speed of approximately 25,000 miles per hour, known as escape velocity, to break free from Earth's gravitational pull. This speed is necessary because it allows the rocket to overcome the gravitational force that keeps it bound to the planet. If the rocket doesn't achieve this velocity, it will not have enough kinetic energy to counteract the gravitational attraction and will eventually fall back to Earth. The escape velocity is influenced by factors such as Earth's mass and radius, and it ensures that the rocket can travel into space without being pulled back.

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to [email protected]. Why does a rocket need to travel at 25,000 miles per hour (approximately 40,000 kilometers per hour) to break free from Earth's gravity? – Bo H., 10 years old, Durham, New Hampshire There’s a reason why a rocket has to go so fast to escape Earth. It’s about gravity – something all of us experience every moment of every day. Gravity is the force that draws you down towards the Earth, and that's beneficial. It ensures that you remain grounded; without it, you would drift off into the vastness of space. But gravity also makes it difficult to leave Earth if you’re a rocket heading for space. Escaping our planet’s gravitational pull is hard – not only is gravity strong, but it also extends far away from Earth. Similar to an inflated balloon. As a rocket scientist, one of the things I do is teach students how rockets overcome gravity. Here’s how it works: Essentially, the rocket has to make thrust – that is, create force – by burning propellant to make hot gases. Then it shoots those hot gases out of a nozzle. It’s sort of like blowing up a balloon, letting go of it and watching it fly away as the air rushes out. View pictures in App save up to 80% data. On July 16, 1969, the Saturn V rocket launched Apollo 11, carrying three American astronauts on their historic journey to the Moon. Image courtesy of Heritage Images/Hulton Archive via Getty Images. More specifically, the rocket propellant consists of both fuel and oxidizer. The fuel is typically something flammable, usually hydrogen, methane or kerosene. The oxidizer is usually liquid oxygen, which reacts with the fuel and allows it to burn. When launching into space and breaking free from Earth's gravity, rockets require a significant amount of force, leading to rapid consumption of propellant. This poses a challenge, as rockets cannot carry an unlimited supply of fuel to maintain continuous thrust; the quantity of propellant necessary would add excessive weight, preventing the rocket from liftoff. What occurs when the fuel is depleted? The propulsion ceases, and gravity begins to decelerate the rocket, eventually leading it to descend back towards Earth. View pictures in App save up to 80% data. A rocket delivers a lateral thrust (indicated by the right arrow), while gravity exerts a downward force toward Earth (shown by the down arrow). The combination of these forces results in the spacecraft's trajectory (marked by the red arrow), allowing it to achieve orbit (illustrated by the yellow path). ESA/ L. Boldt-Christmas Fortunately, scientists can launch the rocket with some sideways momentum so that it misses the Earth when it returns. They can even do this so it continuously falls around the Earth forever. In other words, it goes into orbit, and begins to circle the planet. Many launches intentionally don’t completely leave Earth behind. Thousands of satellites are orbiting our planet right now, and they help phones and TVs work, display weather patterns for meteorologists, and even let you use a credit card to pay for things at the store or gas at the pump. You can sometimes see these satellites in the night sky, including the International Space Station. NASA's Perseverance rover was launched to Mars aboard an Atlas V rocket. Fleeing from Earth But suppose the goal is to let the rocket escape from Earth’s gravity forever so it can fly off into the depths of space. That’s when scientists do a neat trick called staging. They launch with a big rocket, and then, once in space, discard it to use a smaller rocket. That way, the journey can continue without the weight of the bigger rocket, and less propellant is needed.

Photo credit: Joe Raedle via Getty Images. However, staging alone won't suffice; eventually, the rocket will deplete its fuel. Yet, if the rocket reaches a sufficient speed, it can exhaust its propellant and still glide away from Earth indefinitely, unaffected by gravitational pull. It's similar to biking: if you gain enough momentum, you can ascend a hill without needing to pedal. And just like there’s a minimum speed required to coast the bike, there’s a minimum speed a rocket needs to coast away into space: 25,020 mph (about 40,000 kilometers per hour). Scientists call that speed the escape velocity. A rocket needs to go that fast so that the momentum propelling it away from Earth is stronger than the force of gravity pulling it back. Any slower, and you’ll go into an orbit of Earth. Fleeing from Jupiter Larger or more massive objects exert a stronger gravitational force. Therefore, a rocket taking off from a planet that is larger than Earth would require a greater escape velocity to break free from the planet's gravitational influence. For example, Jupiter is the most massive planet in our solar system. It’s so big, it could swallow 1,000 Earths. So it requires a very high escape speed: 133,100 mph (about 214,000 kilometers per hour), more than five times the escape speed of Earth. But the extreme example is a black hole, an object so massive that its escape speed is extraordinarily high. So high, in fact, that even light – which has a speed of 370 million mph (about 600 million kilometers per hour) – is not fast enough to escape. That’s why it’s called a black hole.

Novel organic solar cells demonstrate exceptional durability in tests against space radiation.

Traditionally, silicon and gallium arsenide have been the primary materials used in solar cells, but now a new player is making its way into the spotlight: organic solar cells. View pictures in App save up to 80% data. In order to explore the vastness of space, both space agencies and private companies must first overcome the challenge of securing reliable energy sources. Silicon and gallium arsenide have long been the primary materials used in solar cells, but a new player is making waves: organic solar cells. Constructed from carbon-based substances, these cells present numerous benefits: they are lightweight, adaptable, and could be more cost-effective to manufacture. However, their resilience in the extreme conditions of space has raised significant concerns. A new study conducted by researchers at the University of Michigan examined how proton radiation, a significant hazard in outer space, affects organic solar cells. Earlier studies on organic solar cells in space mainly focused on assessing their overall efficiency following radiation exposure. In contrast, the latest research takes a more in-depth approach by exploring the molecular mechanisms responsible for the decline in performance. "According to Yongxi Li, the lead author of the research, 'Silicon semiconductors face stability issues in space due to proton irradiation from the sun.'" "Li noted, 'We conducted tests on organic photovoltaics using protons, as these particles are regarded as the most harmful to electronic materials in space.'" Adaptable organic cells Gallium arsenide is favored for space missions because of its impressive efficiency in converting sunlight into electricity. This material effectively harnesses a large fraction of solar energy. Additionally, it is resilient against the harmful impacts of protons, which are plentiful in the space environment. Nevertheless, there are some drawbacks associated with it. For example, gallium arsenide is costly to manufacture. Additionally, similar to silicon, it has a considerable weight and is challenging to manipulate, which may restrict its use in space exploration missions.  On the other hand, organic solar cells are recognized for their lightweight and flexible characteristics. These qualities make them appealing for use in space applications, where minimizing weight and the capacity to adapt to curved surfaces are crucial. The objective of this study is to evaluate the durability of organic solar cells when exposed to the extreme conditions of outer space, in order to establish their viability for upcoming space exploration missions. Electron confinement Interestingly, the study found that organic solar cells made with small molecules were highly resistant to proton radiation. The cells displayed no damage after three years of radiation exposure.  Nonetheless, the ones constructed with more intricate polymer frameworks saw a notable drop in efficiency, with nearly 50% of their initial performance diminished. The scientists found that proton radiation has the ability to disrupt chemical bonds in the polymer, leading to the formation of "electron traps" that impede electrical conductivity. "According to Stephen Forrest, the Peter A. Franken Distinguished University Professor of Engineering at the University of Michigan, 'Our research indicates that protons can break down certain side chains, resulting in an electron trap that negatively impacts the efficiency of solar cells.'" The team found that these “traps” can be healed by gently heating the cells. This suggests the possibility of self-healing solar cells that could operate effectively in space. "Forrest mentioned, 'This issue can be resolved through thermal annealing, which involves heating the solar cell. However, we may also discover methods to fill the traps with different atoms, thereby eradicating the problem altogether.'" Research indicates that organic solar cells oriented towards the sun may have the ability to self-repair when exposed to elevated temperatures, approximately 100°C (212°F), a phenomenon that has been documented in controlled laboratory experiments. “But questions remain: for instance, will that repair still take place in the vacuum of space? Is the healing reliable enough for long missions?” the researchers stated in the press release.  On the other hand, scientists are investigating the potential for creating materials that naturally prevent the development of electron traps that can degrade performance. The findings were published in the journal Joule.

Inflatable Starshade for Habitable Exoplanets

View pictures in App save up to 80% data. An artist's illustration showcasing the innovative strategy put forward by the 2025 NIAC-selected Inflatable Starshade for Earth-like Exoplanets project. John MatherNASA Goddard Space Flight Center We will design the first family of ISEE’s (Inflatable Starshade for Earthlike Exoplanets) with sizes from 35 to 100 m diameter. A starshade would enable any telescope to observe exoplanets, a top priority for astronomy worldwide. Compared with other starshade concepts, we aim for a lower mass, cost and complexity, while still providing high performance and science yield (>100 targets). Our starshades would be compatible with the 6 m diameter Habitable Worlds Observatory (HWO) now being planned, as well as the world’s largest telescope, the 39 m diameter European Extremely Large Telescope now being built in Chile, working as part of the HOEE, (Hybrid Observatory for Earthlike Exoplanets), and other future telescopes. We need to observe oxygen at visible wavelengths and ozone at UV. An ISEE, positioned between a target star and the telescope, would block the starlight without blocking the exoplanets. Starshades have perfect optical efficiency, they work with any telescope, and they can block the starlight much better than the requirement, for a star >1010 times brighter than the target. The alternative technology employs an almost flawless and highly stable space telescope, similar to HWO, equipped with an internal coronagraph designed to block starlight from obscuring the planet's image. Coronagraphs offer significant benefits, including their compact size, ease of testing, and immediate availability. Nonetheless, existing coronagraphs have yet to achieve the necessary contrast levels. Additionally, the development of an ultraviolet coronagraph remains unfeasible. If the stringent requirements for extreme picometer stability and optical precision of HWO and its coronagraph could be eased by integrating a starshade, it would allow for the construction of HWO at a significantly reduced cost and lower risk. Therefore, if ultraviolet observations of exoplanets are crucial, utilizing a 35 m starshade in conjunction with HWO emerges as the sole viable option. The HWO is set to be NASA's next major observatory and will feature a high-performance coronagraph designed for exoplanet observation. This decision has shifted the dynamics regarding the competing starshade technology. However, a starshade mission might still be deemed necessary under certain conditions: A. If the HWO and its coronagraph cannot be constructed and validated as needed; B. If the HWO needs to observe exoplanets in UV wavelengths, or if a 6 m HWO is insufficient to target the desired celestial bodies; C. If the HWO does not perform adequately after its launch, and servicing or instrument upgrades are not feasible; D. If HWO observations reveal that intriguing exoplanets are scarce, too far away, obscured by dense dust clouds surrounding their host stars, or cannot be fully analyzed with an upgraded HWO; or E. If HWO findings indicate that the next phase requires UV data, or a telescope significantly larger than what future HWO coronagraph enhancements can provide. An inflatable starshade presents a solution to the primary challenge associated with traditional starshade designs: their complex mechanical structures. Historically, starshades have not been launched, as they require precise shapes and edges, along with accurate propulsion and positioning. Previous designs utilizing discrete components can be enlarged to meet the dimensions needed for HWO (35-60 m) and HOEE (100 m), but they tend to be bulky, difficult to prototype, and thus incur significant costs and risks. Our target mass budget is set at 250 kg for the 35 m HWO variant, 650 kg for the 60 m option, and 1700 kg for the 100 m HOEE model. We plan to refine our concepts and create comprehensive designs along with finite element models to assess strength, stiffness, stability, and thermal performance. Additionally, we will establish small-scale testing facilities to address challenges such as the bonding of large, high-strength material sheets within inflatable configurations. Key deliverables will encompass mass and power budgets, evaluations of strength and stiffness, and laboratory testing of essential components. We will also revise the mission concepts for HWO and HOEE in light of the new starshade specifications.Depending on advancements in the HWO mission, starshades may be essential for enhancing our understanding of exoplanets. An inflatable starshade could facilitate their implementation.

Are you able to decipher cursive writing? It's a unique skill that the National Archives is seeking!

View pictures in App save up to 80% data. View pictures in App save up to 80% data. If you have the ability to read cursive writing, the National Archives would be interested in hearing from you. Alternatively, there are several million. Over two centuries' worth of U.S. documents require transcription (or at the very least, classification), and the overwhelming majority of these are written in cursive handwriting – necessitating individuals who are skilled in this elegant, looping style of writing. "Being able to read cursive is like having a superpower," remarked Suzanne Issacs, who serves as a community manager for the National Archives Catalog in Washington D.C. She is part of the team that coordinates the more than 5,000 Citizen Archivists helping the Archive read and transcribe some of the more than 300 million digitized objects in its catalog. And they're looking for volunteers with an increasingly rare skill. Those records range from Revolutionary War pension records to the field notes of Charles Mason of the Mason-Dixon Line to immigration documents from the 1890s to Japanese evacuation records to the 1950 Census. View pictures in App save up to 80% data. An application for a Revolutionary War Pension submitted by Innit Hollister in August 1832. The National Archives employs Citizen Archivists, who volunteer their time to assist in transcribing these documents. While proficiency in reading cursive handwriting is beneficial, it is not a requirement. "Issacs mentioned that we organize missions inviting volunteers to assist us in transcribing or tagging records within our catalog." To volunteer, all that’s required is to sign up online and then launch in. “There's no application,” she said. “You just pick a pick a record that hasn't been done and read the instructions. It's easy to do for a half hour a day or a week.” Having the ability to read longhand script is incredibly beneficial, as many documents are composed in that style. "It's not solely about whether you were taught cursive in school; it's really about how frequently you utilize cursive in your daily life," she remarked. View pictures in App save up to 80% data. An application for a Revolutionary War Pension was submitted on April 29, 1852. The National Archives engages Citizen Archivists, who volunteer their time to assist in transcribing these historical documents. Being able to read cursive writing is quite beneficial for this task. Cursive writing has become less common. The ability of Americans to use this interconnected style of writing has been gradually declining over the years. School children were once taught impeccable copperplate handwriting and penmanship was something they were graded on. That began to change when typewriters first came into common use in the business world in the 1890s and was further supplanted in the 1980s by computers. Still, handwriting continued to be considered a necessary skill until the 1990s when many people shifted to e-mail and then in the 2000s to texting. By 2010, the Common Core teaching standards emphasized keyboard skills (once taught as “typewriting”) and no longer required handwriting on the presumption that most of the writing students would do would be on computers. That led to a pushback and today at least 14 states require that cursive handwriting be taught, including California in 2023. But it doesn’t mean that they actual use it in real life. In the past, most American students began learning to write in cursive in third grade, making it a rite of passage, said Jaime Cantrell, a professor of English at Texas A&M University Texarkana whose students take part in the Citizen Archivist work, putting their skills reading old documents to work. View pictures in App save up to 80% data. On January 23, 2024, a student at Orangethorpe Elementary School in Fullerton, California, is seen practicing cursive writing. This year, California grade school students are mandated to learn cursive handwriting as part of their curriculum. For people of her generation, she explained, “cursive represented a milestone in literacy during the 1980s. We mastered cursive and suddenly we could write in the same way that adults did.” She mentioned that although many of her students learned cursive in school, they rarely use or read it. She knows this because she provides feedback on their papers using cursive writing. A few of her students have stopped typing altogether. They now rely on talk-to-text tools or even artificial intelligence. "I can tell because the lack of punctuation makes it flow like a stream of consciousness," she observed. Mastering the cojoined script can be a challenging endeavor, but it is certainly achievable. Doing so grants you access to a treasure trove of historical documents. For many, cursive writing remains a valuable skill. California passed a law in 2023 requiring that “cursive or joined italics” be taught for grades one through six. The law’s author said it was so students could read primary source historical documents. That’s exactly how Cantrell’s students use it. One of the classes she teaches involves deciphering documents written in the 18th and 19th centuries – and one of their projects is to get involved in the National Archive’s transcription work. Cantrell remarked, “There’s definitely a learning curve involved. However, my students persevere. They sense a responsibility and believe they are contributing positively.” Being able to read cursive is just the start to deciphering older documents, said the National Archive’s Nancy Sullivan. The handwriting of the 18th and 19th centuries isn’t what today’s third-grader are taught. "Sometimes, the oldest texts can be the most straightforward to understand," Cantrell remarked. "Examining the correspondence between Abigail Adams and her husband, President John Adams, reveals that the cursive writing is truly an art form; it's remarkably consistent," she remarked. The capabilities of artificial intelligence in understanding cursive writing have their limitations. According to Sullivan from the National Archive, artificial intelligence is beginning to decipher cursive writing, but it still requires assistance from humans. The Archives has collaborated with FamilySearch, a non-profit organization focused on genealogy and operated by the Church of Jesus Christ of Latter-day Saints, which provides complimentary genealogical software, search capabilities, and access to historical records. FamilySearch has created an AI tool designed to interpret handwritten documents. However, a human is still needed to perform the final editing. "Typically, there are a few errors," she explained. "That's why we refer to it as 'extracted text,' and our volunteers need to review it and check it against the original document." It is only after a volunteer has thoroughly examined the text that it is deemed a proper transcription. According to Issacs, AI is not always able to interpret the frequently challenging documents that volunteers encounter. These documents may be damaged, stained, creased, or worn. For instance, when it comes to pension applications from the Revolutionary War, widows needed to validate their marriages, which led them to include handwritten pages of family trees that were often ripped out from their family Bibles. Let's not overlook the issue of poor penmanship. “The handwriting of some Justices of the Peace is dreadful,” remarked volunteer Christine Ritter, 70, a resident of Fairless Hills, Pennsylvania. The document is filled with cross-outs, notes scrawled on the reverse side that seep through, quirky and creative spellings, and archaic letter forms (for instance, a double S might appear as a "long s," resembling an F). Additionally, you'll find children's doodles layered on top. There are also numerous outdated terms and legal jargon that can confuse even the most knowledgeable readers. “It’s like piecing together a puzzle, and I find it truly enjoyable,” shared volunteer Tiffany Meeks, 37. She began her journey as a transcriber in June and discovered a new term – paleography, which involves interpreting ancient manuscripts. “I felt as though I was picking up a completely new language. I was not only revisiting my cursive skills but also my old English,” she remarked. “I discovered a new term: paleography,” which refers to the study of deciphering ancient texts. No cursive? That's perfectly fine! Issacs from the Archive emphasizes that volunteers are not required to have prior knowledge of cursive writing; you can pick it up as you go. "It can be beneficial, but it's not essential." For instance, there is a feature called "no cursive needed" available for individuals examining pension records from the Revolutionary War. Rather than directly reading and transcribing these documents, volunteers have the opportunity to assist by adding "tags" to records that have already been transcribed by fellow Citizen Archivists, making them more searchable. "You can learn it gradually as you progress," Ritter mentioned. "When I received the document for the first time, I was taken aback and thought, 'Wow, this is impossible to read.' It made me anxious. However, as I continued to work with them, it became much more manageable," she remarked. Ritter’s working on Revolutionary War pension files for soldiers who served at the Battle of Guildford Courthouse on March 15, 1781. As she works, she imagines how much it will mean to families to find something so old about one of their relatives. She recalls a time when she took great pride in her impeccable penmanship, but nowadays she describes her handwriting as “terrible.” Nevertheless, she still excels at reading cursive and has turned it into a delightful hobby. "I rise early in the morning and share breakfast with my husband before he heads out for a fishing trip. After that, I retreat to my workspace, where my computer awaits. I tune into my favorite oldies radio station and dive into my transcription work," she shared. "It's something I truly enjoy."

Ancient Climate Record Retrieved from Antarctic Ice Sheet Remains Intact

View pictures in App save up to 80% data. The ice core extracted from Little Dome C. (PNRA/IPEV) A massive ice core sample extracted from Antarctica could hold the most ancient, continuous record of Earth's climate, extending over a million years into the past. If laid out flat, the complete length of the ice core, measuring 2,800 meters (9,186 feet), would stretch beyond the Golden Gate Bridge in San Francisco. Each meter-long segment contains up to 13,000 years of deep, compressed history, including bubbles of ancient air. Together, the evidence provides a baseline for our current climate crisis, and it could reveal more about past extreme climate change events that threatened human survival. "We have a strong indication that the uppermost 2,480 meters contain a climate record that goes back to 1.2 million years," says Julien Westhoff, chief scientist on the ground for the European Project for Ice Coring in Antarctica (EPICA). More analysis is required, but there is a possibility that the deepest sections of the drilling may hold ice from the pre-Quaternary era, which is over 2.5 million years old. View pictures in App save up to 80% data. A portion of the ice core. (PNRA/IPEV) The oldest ice uncovered in Antarctica so far dates back 2.7 million years, but Earth's movements pushed this ice into a shallower patch of frozen material, so it doesn't provide a continuous climate chronicle; it's more of a snapshot. Previously, the EPICA record for the oldest vertical ice core covered the last 740,000 years or so, and it was obtained in 2004. Ice cores are precious to scientists, because they trap particles, water isotopes, and bubbles of atmospheric gases, like carbon dioxide and methane. This allows researchers to reconstruct climates and environments in our planet's history. Recent drilling efforts in East Antarctica reveal information about a timeframe during which the Earth's glacial cycles unexpectedly extended, occurring between 900,000 and 1.2 million years ago. Some scientists suspect nearly 99 percent of early humans in Africa may have died out during this period of extreme cold swings, although that hypothesis remains contentious and is mostly based on modern genetic data. The newly retrieved ice core from Antarctica has the potential to uncover further insights into Earth's climatic changes during this period. Additionally, it is likely to validate the extent to which human-induced emissions have disrupted the planet's natural glaciation cycles. "This transition remains a scientific mystery, particularly regarding the role of greenhouse gases and ice sheet dynamics," Carlo Barbante, director of EPICA, told CNN. "This information allows us to grasp the complex connection between greenhouse gases and global temperatures spanning hundreds of thousands of years, extending now to 1.2 million years and potentially further." The extraction site of the recent drilling is called Little Dome C, in East Antarctica, and it was chosen because radar surveys revealed the presence of extremely thick ice here, layered like a cake, with a bottom that had not yet melted away. At 3,200 meters above sea level – high on Antarctica's central plateau – summer temperatures on Little Dome C sit around -35 ºC (-31 ºF) and often there are high wind speeds to contend with as well. Researchers at EPICA, including scientists from the British Antarctic Survey, had their work cut out for them. It took about 20 days just to deliver all their infrastructure and cargo to the site from a nearby research station. View pictures in App save up to 80% data. Storage of ice core samples. (PNRA/IPEV) As drilling commenced, an isotopic analysis system was capable of detecting glacial and interglacial cycles nearly instantly, with each segment of the ice core being retrieved from the earth. This is the reason why researchers at EPICA are making significant assertions so early in their study. Today, the Antarctic ice sheet holds 90 percent of our planet's ice. A drilling like this one, straight from its belly, could reveal just how Earth's southernmost continent came to hog most of its freshwater. Climate scientist Richard Alley, who was not involved in the recent drilling effort, told the Associated Press that EPICA's ice core was "truly, truly, amazingly fantastic." Alley forecasted, "They will discover amazing knowledge."

The meme "Will Smith enjoying a plate of spaghetti" marks the inaugural AI benchmark meme.

Perhaps the sole one? View pictures in App save up to 80% data. AI video generators have made significant strides in their brief history, and an unexpected benchmark that many of us use to gauge this advancement has—due to various reasons—manifested as videos of Will Smith enjoying spaghetti.

AI generators have consistently struggled with accurately depicting food (which frequently appears distorted), hands (which seldom show the right number of fingers), and the intricacies of the eating process as a whole. Additionally, the abundance of noodles adds another layer of complexity for the AI to manage. But culturally speaking, as with any meme, the why doesn’t so much matter. It is as much a method of communication as it is an inside joke. Much like the Utah Teapot of the late ’70s and ’80s—a famous 3D model and computer graphics benchmark that was kind of a pre-meme meme—Will Smith eating spaghetti videos have become a cultural reference that breaches the gap between tech and pop culture. It has become an AI litmus test for the layman, a way for the culture at large to participate and track developments in the latest big tech wave. 2023 AI Will Smith eating spaghetti was comically gruesome. 2024 AI Will Smith eating spaghetti is plausible. 2025 AI Will Smith eating spaghetti might not be recognizable as AI at all (the actor’s real-life parody of the spaghetti-eating videos is undoubtedly hastening this certainty, providing generators with more exact data to replicate). At which point AI benchmarks will become more difficult to articulate and define, and memes will continue to feel more niche as the social internet grows increasingly fragmented. Tutto passa.

BepiColombo Successfully Concludes Last Flyby of Mercury, Set for Orbital Mission in 2026

Initiated on October 18, 2018, BepiColombo stands as the second and most intricate mission ever designed to orbit the planet Mercury. View pictures in App save up to 80% data. The enigmatic north pole of Mercury unveiled by M-CAM 1 (ESA) The European Space Agency’s BepiColombo‘s sixth and final Mercury flyby, executed on January 8, 2025, successfully set the stage for its planned orbit insertion in late 2026. The ESA/JAXA mission skimmed just a few hundred kilometers above Mercury’s north pole, capturing close-up images revealing potentially icy, permanently shadowed craters and the expansive sunlit northern plains. At 06:59 CET, BepiColombo soared to an altitude of just 295 km above the cold, shadowy night side of Mercury. Approximately seven minutes later, it flew directly over the planet's north pole, offering clear perspectives of Mercury's sunlit northern hemisphere. Following its passage through Mercury’s shadow, BepiColombo’s monitoring camera 1 (M-CAM 1) captured the initial detailed images of Mercury’s surface. As it soared over the ‘terminator’ – the dividing line between daylight and darkness – the spacecraft seized a rare chance to look directly into the perpetually shadowed craters located at the planet's northern pole.

China's 'Batwoman' researcher continues to carry out hazardous coronavirus experiments despite concerns over lab leaks.

Chinese researcher Shi Zhengli, aged 60, remains actively engaged in studying bat coronaviruses in Wuhan. Leading virologists warn that her research could have a 'potentially catastrophic' effect as we approach five years since the onset of the Covid-19 pandemic. View pictures in App save up to 80% data. Chinese virologist Shi Zhengli has allegedly earned the nickname 'batwoman' (file). A Chinese scientist is still conducting "potentially catastrophic" research into coronaviruses five years on from the start of the Covid pandemic which claimed millions of lives worldwide, according to experts. Shi Zhengli, 60, is one of the world's leading scientists working on bat coronaviruses in Wuhan. She has reportedly earned herself the nickname "Batwoman" as a result. She was thrown into the spotlight in late 2019 when a new form of coronavirus emerged in the region, with some scientists questioning whether Covid-19 leaked from a lab. In December, a two-year congressional investigation into the pandemic concluded the "weight of the evidence" suggests a lab leak was responsible. US lawmakers said in the report: "More and more senior intelligence officials, politicians, science editors, and scientists increasingly have endorsed the hypothesis that Covid-19 emerged as the result of a laboratory or research related accident." View pictures in App save up to 80% data. Her ongoing research has been labeled as 'potentially disastrous' (file). Nevertheless, leading virologists assert that Zhengli's team is still engaged in potentially harmful coronavirus research in Wuhan. In a study released in Nature, she proudly highlighted her team's achievement in creating the first "tailored" coronavirus "receptors." This advancement could enable researchers to modify viruses, allowing them to infect various species, including humans. Robert Redfield, the director of America's CDC during the pandemic, told The Sun: "It's potentially dangerous research. You are taking a non-pathogenic virus and changing it so that it could end up being dangerous to humans. You may have a pathogen that is restricted to pigs - but now you could totally change it so that it's highly infectious to other species too. View pictures in App save up to 80% data. An expert notes that Zhengli is 'experimenting with bat viruses and altering their receptors' (file). "She is experimenting with bat viruses and altering their receptors, which could enable them to infect animals like cows or chickens. This is a risky move with potentially disastrous outcomes. It might lead to a new pandemic affecting either animals or humans." Dr. Alina Chan, an expert in genetic engineering, stated that it seems Zhengli's team has now succeeded in "isolating" additional novel coronaviruses. She expressed concerns that this research is "risky" and prompts inquiries about the intentions of Zhengli's team regarding the handling of these new viruses once they cultivate them in the laboratory.

Scientists stumble upon a surprising finding in their efforts to enhance desalination processes: 'Remarkably convenient and budget-friendly'

View pictures in App save up to 80% data. The earlier benchmark for seawater was 8% less than that of pure water, marking this as a significant milestone. Researchers at the University of South Australia have made a major breakthrough in addressing global water scarcity, according to Tech Xplore. While more than 70% of the Earth's surface is water, most of it resides in the oceans, making it unsuitable for drinking. Currently, approximately 36% of the world's population lacks access to freshwater for a minimum of four months annually, and this figure could potentially double in the next few decades, according to Tech Xplore. Still, the ocean blue presents an opportunity: seawater can be evaporated, stripped of the high salt content that makes it unusable, and then turned into safe, drinkable water.  Would you consider installing hydropanels for water collection on your house? Absolutely! I'm uncertain. Absolutely not! If the funding comes from the government Select your option to view the outcomes and share your thoughts. The problem with this thermal desalination method has always been the large amount of energy it needs and the slow rate of evaporation. That's where the study's findings, published in the Advanced Materials journal, come in.  The researchers successfully increased the evaporation rate of seawater, achieving a rate that is 18.8% greater than that of pure water. Previously, seawater's evaporation rate was 8% lower than that of pure water, marking this development as a significant milestone, according to Tech Xplore. In order to achieve this remarkable result, scientists introduced a mixture of minerals into the tank containing evaporating seawater. Professor Haolan Xu, one of the authors of the research, explained that the resulting chemical reactions involve an exchange of ions at the interface of air and water, which accelerates the evaporation process, as reported by the outlet. Check it out: Would you consider wearing a shirt crafted from oysters? In addition to the improved efficiency, the minerals are both easily accessible and affordable, which contributes to the overall convenience and cost-effectiveness of the process, Professor Xu explained to Tech Xplore.  With about 17,000 desalination plants worldwide, this breakthrough can have an immediate impact in boosting the amount of clean water available to those who need it — although there are environmental drawbacks to consider. Researchers hope to continue pushing the speed of evaporation in the future to further secure the global water supply, Tech Xplore reported. According to Prof. Xu, as reported by Tech Xplore, "This innovative approach can be seamlessly incorporated into current evaporation-driven desalination technologies, significantly increasing the availability of clean water for billions around the globe."

A mysterious metallic ring with a radiant glow plummeted to the ground, leaving everyone puzzled about its origin and purpose.

View pictures in App save up to 80% data. A glimpse of the metal ring, approximately 8 feet in diameter, that descended from the sky into Mukuku village on December 30 in the eastern region of Makueni County, Kenya. Over a week has passed since initial reports surfaced regarding a "luminescent metal ring" that descended from the sky and landed close to a secluded village in Kenya. According to the Kenya Space Agency, the object weighed 1,100 pounds (500 kg) and had a diameter of more than 8 feet (2.4 meters) when measured after it landed on December 30. A couple of days later, the space agency confidently reported that the object was a piece of space debris, saying it was a ring that separated from a rocket. "Such objects are usually designed to burn up as they re-enter the Earth’s atmosphere or to fall over unoccupied areas, such as the oceans," the space agency told The New York Times. Following the release of the initial reports in Western media, a group of committed space enthusiasts has been leveraging open source information to pinpoint the exact space object that landed in Kenya. As of now, they have yet to determine the specific rocket launch associated with the large ring. Currently, certain space observers suspect that the object might not have originated from outer space at all. Did it actually originate from outer space? The space environment is becoming more congested; however, significant pieces of metal from rockets are typically not drifting unnoticed and unmonitored in Earth's orbit. "It was suggested that the ring is space debris, but the evidence is marginal," wrote Jonathan McDowell, an astrophysicist working at the Harvard-Smithsonian Center for Astrophysics. McDowell is highly regarded for his analysis of space objects. "The most likely space-related possibility is the reentry of the SYLDA adapter from the Ariane V184 flight, object 33155. Nevertheless, I am not fully convinced that the ring is space debris at all," he wrote. Another prominent space tracker, Marco Langbroek, believes it's plausible that the ring came from space, so he investigated further into objects that may have returned around the time of the object's discovery in Kenya. In a blog post written Wednesday he noted that apart from the metal ring, other fragments looking consistent with space debris—including material that looks like carbon wrap and isolation foil—were found several kilometers away from the ring.

The Prototype: Research Indicates AI Tools May Diminish Critical Thinking Abilities

In this week’s edition of The Prototype, we look at how too much reliance on AI assistants could make it harder to think, a company building bioengineered arteries, the role viruses play in Alzheimer’s and more. You can sign up to get The Prototype in your inbox here. New AI tools are slowly becoming ubiquitous, being added to the software and hardware we use every day (sometimes whether we like it or not). But if we’re using artificial intelligence to perform tasks, search for information and solve problems, what does that mean for the intelligence we’re born with? To figure this out, a team of researchers conducted a study involving 666 individuals ages 17 and up, representing a diverse population. It first evaluated the extent to which each of them made use of AI tools, then tested their critical thinking skills. The results of the study, which were published in the journal Societies, found that those who used AI tools a lot showed worse critical thinking abilities than those who didn’t use them often or at all. Whether someone used AI tools was a bigger predictor of a person’s thinking skills than any other factor, including educational attainment. This occurs due to a process known as "cognitive offloading," wherein individuals outsource their thinking and problem-solving tasks. Regular reliance on cognitive offloading can diminish one's capacity for independent thought and problem resolution. The authors of the study noted, "This dynamic highlights the dual nature of AI technology. Although it boosts efficiency and ease of use, it unintentionally cultivates a reliance that may weaken critical thinking abilities as time goes on." These results align with previous research indicating that AI tools may adversely affect critical thinking abilities. Nevertheless, the authors highlight that some studies suggest these tools can be advantageous when they support critical thinking instead of replacing it. "Further research should investigate methods to incorporate AI tools in ways that boost cognitive involvement rather than obstruct it," they stated. "It is essential to prepare the upcoming generation with the skills needed to maneuver through a progressively intricate digital environment." Keep watching for updates. Ready-Made Bioengineered Arteries for Trauma Victims Every year, thousands of Americans receive traumatic injuries that damage the arteries that crucially carry blood to their limbs. When these occur, patients basically have three options, Laura Niklason, CEO of regenerative medicine startup Humacyte, told me: they can have a vein grafted from another part of their body, which takes extra time and causes additional trauma; the surgeon can replace the artery with a synthetic plastic one, which creates a high risk of infection; or the limb can be amputated. Niklason presents a fourth alternative: her company has created a bioengineered artery known as Symvess, which can be surgically inserted into a patient’s body. This innovative solution aids in preserving the limb while also minimizing the chances of infection. Symvess is made from human donor cells cultivated in a laboratory on a biodegradable scaffold, produced in batches of 200. As time progresses, these cells reconstruct the physical framework of a blood vessel. After this process is complete, the living cells are removed, leaving behind the artery structure that can be safely implanted in a new patient without the risk of rejection. Subsequently, the cells from the patient's body fill the implant, effectively regenerating a new artery. Last month, Symvess was approved by the FDA for use in patients with traumatic injuries. That approval was based on studies that showed that the product, which has been implanted in over 600 patients so far, is significantly less likely to cause infection or lead to limb amputation compared to conventional synthetic arteries made from plastic. In its upcoming initiatives, the company plans to collaborate with Medicare and private insurance providers to secure coverage for transplant procedures involving Symvess. Additionally, it is undertaking research to explore the application of Symvess in patients undergoing kidney dialysis and those suffering from pulmonary arterial hypertension. Furthermore, the company is in the process of creating a more compact version of its product, which may be suitable for heart bypass patients. "This technology is genuinely unprecedented, and the FDA required extensive data review before they felt assured enough to approve it," remarked Niklason. "I’m really pleased to be part of this." WEEKLY DISCOVERY: DORMANT VIRUSES COULD TRIGGER NEURODEGENERATIVE DISEASES It’s long been known that repeated head injuries can lead to neurodegenerative diseases like Parkinson’s, Alzheimer’s and CTE. But it wasn’t clear exactly how that happened. New research suggests the answer may be dormant viruses, particularly herpes simplex 1, which is found in the brains of over 80% of the population. These findings were reached by growing small tissue models of the brain, some with the herpes virus and some without, which were then struck repeatedly with a piston to mimic concussion. The study, which was published in Science Signalling, found that the brain tissues with the virus developed signs of Alzheimer’s disease, while those without did not, and that the damage was markedly increased with repeated blows. The researchers plan to conduct future studies that explore whether exposure to antiviral or anti-inflammatory drugs shortly after an injury could help prevent the onset of Alzheimer’s. LAST BOUNDARY: TESTING WATER-BASED PROPULSION SYSTEMS Japanese startup Pale Blue announced it has signed a deal with Italy-based company D-Orbit to conduct two demonstrations in-orbit of its new ion thruster, which allows satellites both to maneuver and to take themselves out of orbit at the end of their life. Pale Blue’s thruster uses water as a propellant, which potentially offers a cleaner and more sustainable fuel for small satellites. HERE'S WHAT I WROTE THIS WEEK In my other newsletter, InnovationRx, my colleague Amy Feldman and I covered a number of healthcare stories, including a drug that significantly improves survival for lung cancer patients, the controversy over pulse oximetry technology and a new study that finds that while LLMs are good at answering medical exam questions, they’re much less proficient at making diagnoses from patient conversations. SCIENCE AND TECHNOLOGY BITS My colleague Jeremy Bogaisky reports that online retailers like Amazon and Alibaba are selling technology that protects drones from having their signals jammed or being remotely taken over. Ai startup Anthropic’s new funding round will make all seven of its founders billionaires, write my colleagues Alex Konrad and Phoebe Liu. Researchers developed a technique for refrigerating quantum computers in a way that reduces errors and could potentially make them more reliable. Eating grapefruit can interfere with the action of several kinds of medications, including anti-anxiety drugs and statins. But new research suggests it may be possible to grow a variety of the fruit that doesn’t interfere with prescription drugs. Biologists successfully transplanted chloroplasts–the cells that power photosynthesis– from algae into hamsters, where they successfully functioned for about three days. Scientists at Northwestern University built a battery that uses triphenylphosphine oxide, a common industrial waste product, to store energy instead of metals. PRO SCIENCE TIP: MOISTEN YOUR COFFEE BEANS WITH WATER Here’s an easy tip to enhance the flavor of your morning cup of coffee: add a little water to the beans before you grind them. This isn’t a new idea–among coffee professionals this is known as the “Ross Droplet Technique”–but new research gives scientific backing to the idea. When beans are ground, they build up a static electric charge, which causes clumping and inconsistent extraction during the brewing process. In new research published in the journal Matter, scientists found that the Ross Droplet Technique reduced the static charge during grinding, producing a better-tasting coffee. WHAT'S CAPTURING MY INTEREST THIS WEEK I’ve been listening to the concept album Epic by Jorge Rivera-Herrans. It’s a musical-style adaptation of The Odyssey, telling the tale of Odysseus from the end of the Trojan War until his return home to Ithaca. The album is divided into nine sagas of a few songs each, serving as chapters in the story. It’s an amazing version of one of humanity’s oldest stories, and it’s appropriate for it to be sung–that is, after all, how it was originally presented in the time of Homer. It’s streaming on most of the major music services. ADDITIONAL INSIGHTS FROM FORBES Forbes reports that Eric Schmidt's latest secret initiative is an AI video platform named 'Hooglee'.

Experts indicate the age at which you're most inclined to form lasting friendships.

Researchers have provided insights into why friendships formed during this period tend to endure for a significant length of time. View pictures in App save up to 80% data. I think we can all acknowledge that having friends is incredibly valuable. Yes, family is also important, but some studies have suggested that it is friendships that make more of a positive impact on your life - lifespan in particular. For example, a 2005 study in Australia found that people who had more friends than other participants tended to outlive those with fewer by 22 percent, Inc. reported last year. A separate study revealed that those with strong social ties had a 50 percent better chance of survival. View pictures in App save up to 80% data. Research indicates that individuals with robust social connections tend to have a longer lifespan (Getty Stock Image) As you age, you begin to realize that friendships can be transient; however, there are a handful of individuals who will remain your companions for a lifetime. According to experts, it ultimately boils down to timing. Research has shown that most people will at least maintain adolescent friendships into adulthood, reports The i In fact, a recent study conducted by the newspaper found that 83 percent of Brits over the age of 30 are still friends with people they befriended at school or college. Adolescence is typically characterized as the period ranging from ages 10 to 24. View pictures in App save up to 80% data. Studies indicate that friendships formed during teenage years tend to endure throughout a person's life (Getty Stock Image). It seems that there are compelling reasons why the friendships you build during that period are more likely to endure over the course of your life. Experts have described this moment as a 'pivotal time'. Sarah-Jayne Blakemore, a Professor of Cognitive Neuroscience at Cambridge University, stated: "Adolescence represents a crucial phase for forming friendships, and the bonds created during this period can last for many years." "It is a period of our lives in which we undergo large changes in our sense of self, and particularly our ‘social self’ - the way we depict ourselves to other people. This includes what peer group we want to be part of and our social relationships." View pictures in App save up to 80% data. Certain individuals maintain lifelong friendships (Getty Stock Image) The bonds of friendship established between the ages of 10 and 24 are strengthened because 'the brain is designed to prioritize new experiences' during this developmental phase. Many of these experiences will be linked to the friends we shared them with, making them deeply embedded in our memories. It is also proposed that the friends you make during that period play a significant role in shaping who you grow into as an adult. Blakemore stated, "During adolescence, the brain exhibits a high degree of plasticity and adaptability, especially in areas associated with social functions." "This indicates that your social surroundings, including the individuals near you and your relationships with peers, could significantly influence the growth and development of your brain."

The Exciting Mathematics of 2025 (Featuring Two Demonstrations of a Classic Greek Theorem)

Say goodbye to the tetrahedron and welcome the generalized enneadecagon! Welcome to 2025! A lovely year, filled with excellent things. Obviously, we’re not talking about the state of the planet – that’s pretty terrible, all things considered. But the math? That is delectable. The spatial design of 2025 One of the most straightforward observations about the upcoming year is that 2025 is a perfect square. Specifically, it can be expressed as 45 multiplied by 45, indicating that if we were to create a large square with each side measuring 45 units, the overall area would amount to 2025 square units.  View pictures in App save up to 80% data. Feel free to verify the numbers for yourself if you're skeptical. Image credit: ©IFLScience That’s not all, though: because it’s an odd square, it’s also a centered octagonal number – which, much like with square numbers, is precisely what it sounds like: it means we can draw a perfect octagon using exactly 2025 pieces. Let's delve into something even more intricate: 2025 is classified as an enneadecagonal number (for those who aren't familiar with geometric terminology, that's a shape with 19 sides). However, there's a catch – it happens to be a negative enneadecagonal number, specifically the -15th one, which makes it quite impossible to visualize.  We are confident in its accuracy because every enneadecagonal number can be expressed using the following formula: Nm = m(17m - 15)/2 and plopping m = -15 into this recipe gives us 2025. The titles of 2025 Along with square, octagonal, and enneadecagonal, 2025 has a few pretty names. It’s a powerful number: an integer m such that if p|m, then p2|m. The reason for that is fairly simple – it’s 452, which is equal to (32)2×52 – or in other words, every prime factor of it turns up at least twice. It’s classified as a refactorable number, or tau number, indicating that it can be divided by the total count of its divisors. For instance, consider the number 18: it has six divisors, which are 1, 2, 3, 6, 9, and 18, and it can be evenly divided by six. In the same vein, the number 2025 possesses 15 divisors, with one of them being 15. To enumerate them all, the complete list of divisors for 2025 includes 1, 3, 5, 9, 15, 25, 27, 45, 75, 81, 135, 225, 405, 675, and 2025. Theorems from the year 2025 Let’s get onto the good stuff, shall we? We’ve already seen that 2025 is a perfect square, but dig a little deeper and we see some even prettier patterns. Forty-five, the number’s square root, is also a triangular number, and that means we can write it as a sum of consecutive numbers. Like this: 45 = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9. This indicates that  2025 = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)2,  which is nice for sure, but that’s not all. Thanks to Nicomachus, an ancient Greek follower of Pythagoras who lived between around 60 CE and 120 CE, we know that numbers that can be written like this – the squares of triangular numbers – also have another interesting property: they can be rewritten as the sum of the cubes of those same numbers. In other words, because  2025 = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)2, we are also aware that  2025 = 13 + 23 + 33 + 43 + 53 + 63 + 73 + 83 + 93. Isn't that awesome?! There are several methods to demonstrate this – one of the most elegant is through this proof that doesn't require any words: View pictures in App save up to 80% data. Pretty cool, right? Photo credit: Cmglee, CC BY-SA 3.0, sourced from Wikimedia Commons. An alternative approach involves utilizing the characteristics of square and cube numbers directly. In reality, it is this method that earns old Nicomachus his recognition, rather than the mere observation of the theorem. His namesake result takes a step back and, in a technical sense, states the following: ∀n∈N>0 : n3 = (n2 − n+1) + (n2 − n+3) + … + (n2 + n−1). That might look… well, like it’s written in another language, and it sort of is, but really it just means that any number n cubed can be written as the sum of n consecutive odd numbers beginning at (n2 − n+1). Like this:  1 等于 1 8 can be expressed as the sum of 3 and 5. 27 can be expressed as the sum of 7, 9, and 11. 64 can be expressed as the sum of the numbers 13, 15, 17, and 19. 125 = 21 + 23 + 25 + 27 + 29 and so forth. Now, written out like that, you can probably see a nice pattern already, right? If you sum up the first k cubed numbers, you’re going to get 13 + 23 + 33 + … + k3 = 1 + 3 + 5 + 7 + 9 + 11 + … + (k2 − k+1) + (k2 − k+3) + … + (k2 + k−1). Now, let's examine square numbers. They exhibit a similar pattern and can be expressed in the following manner: 1 等于 1 4 可以表示为 1 加 3。 9 = 1 + 2 + 6 16 can be expressed as the sum of the first four odd numbers: 1 + 3 + 5 + 7. 25 = 1 + 3 + 5 + 7 + 9 and so on – that is, the square of n is equal to the sum of the first n odd numbers.  But guess what? That sum we found before is precisely that – it’s the sum of the first (k2 + k)/2 odd numbers! In other words, 1 + 3 + 5 + 7 + 9 + 11 + … + (k2 − k+1) + (k2 − k+3) + … + (k2 + k−1) = ((k2 + k)/2)2. So there’s just one thing left to prove, and that’s that (k2 + k)/2 is equal to the sum of the first k natural numbers. Luckily, that’s pretty easy – it’s the definition of a triangular number (or, if you prefer, you can do it visually:  View pictures in App save up to 80% data. The shaded area representing the triangular number is equal to half of the area of the n x (n+1) rectangle. Image credit: ©IFLScience However you prove it, though, the math doesn’t lie: the sum of (n cubes) equals the (sum of n) squared. And now is as good a time as any to rave about this nice little result, since 2025 proves it perfectly. Happy New Year!

Lemurs Face Extinction Threat, Even with Their Remarkable Genetic Diversity

View pictures in App save up to 80% data. Sergiy - stock.adobe.com - for illustrative purposes only The development of lemurs is regarded as distinctive since they underwent evolution in complete seclusion on the island of Madagascar millions of years ago. The island boasted a variety of ecosystems, featuring lush tropical forests in the eastern region and arid, dry landscapes in the southwestern part. This resulted in a variety of lemur species, from tiny mouse-sized creatures to massive sloth-like varieties. The lemurs we are familiar with today are small, have large eyes, and inhabit trees. Over 100 species inhabit Madagascar, showcasing significant genetic diversity among them. However, a staggering 90 percent face the threat of extinction. A group of researchers from Spain aimed to uncover the reasons behind the critical endangerment of numerous lemur species, even though they exhibit significant genetic diversity. To achieve this, they analyzed the genomes of 162 lemurs representing 50 distinct species found throughout Madagascar. Their research uncovered the ways in which ecological elements, changes in climate, and recent human actions have influenced the genetic diversity of lemurs throughout history. "According to Joseph Orkin, the lead researcher of the study, 'As climate changes intermittently linked previously isolated environments, lemurs from various species and groups began to interbreed, exchanging genetic material that enhanced their overall diversity.'" "Additionally, it seems that the species with the greatest diversity are those that have fragmented populations spread throughout various ecosystems on the island. This trend of isolation followed by reconnection appears to be enhancing and redistributing genetic diversity across the entire island." Recent human actions have significantly contributed to the decline of lemur populations. Evidence indicates that factors such as deforestation, the growth of human populations, and changes in hunting methods are closely linked to the onset of dramatic decreases in lemur numbers. View pictures in App save up to 80% data. Sergiy – stock.adobe.com – for illustrative purposes only The exact timeline of the first human arrival in Madagascar remains unclear, but it is believed that their population started to increase around a millennium ago. By the 1700s, the island had undergone considerable transformations in its environment. “Upon examining the genetic data related to population decreases, we consistently identified two notable inflection points occurring approximately 1,000 and 300 years ago. It was quite remarkable to observe such a distinct correlation between the periods of human population growth and the reduction in lemur populations,” Orkin remarked. These results may play a vital role in influencing future conservation strategies. The reduction of habitats and deforestation pose significant risks to lemurs by decreasing their population numbers and disrupting the natural links between habitats that facilitated gene flow. In the absence of varied genetic exchanges, the likelihood of inbreeding increases, thereby heightening the risks for species that are already at a disadvantage. Madagascar is just one of many regions worldwide experiencing a decline in biodiversity. The growing human population is driving this issue on a global scale. By increasing our understanding of how human actions impact biodiversity, we can discover more effective ways to safeguard it. The details of the study were published in the journal Nature Ecology & Evolution. More About:Animals

The Department of the Interior has completed the Western Solar Plan, which now encompasses the state of Wyoming.

On December 20, 2024, the Department of the Interior (DOI) unveiled a revised Western Solar Plan aimed at facilitating efficient and eco-friendly solar energy permitting on public lands across the western United States.  The initiatives of the Department of the Interior (DOI) pertaining to clean energy on public lands are managed by the Bureau of Land Management (BLM). As of 2021, the BLM has successfully authorized 45 renewable energy projects on these lands, exceeding its target of permitting 25 gigawatts of renewable energy by the year 2025. As per the DOI, the revised strategy intends to direct the siting of solar energy initiatives in regions with minimal resource conflicts. It aims to bolster the development of the nation’s expanding clean energy sector, lower energy expenses for consumers, generate high-quality job opportunities, tackle the climate emergency, and promote priorities related to clean air and environmental justice.  This initiative is in line with the broader objective of attaining a fully clean electricity grid by the year 2035.  According to the DOI, “The revised Western Solar Plan recognizes that there are more than 31 million acres of public land available across 11 western states for utility-scale solar project proposals. Nevertheless, it is estimated that only about 700,000 acres will likely be utilized by 2045 to satisfy the expected demand.” The initial Western Solar Plan encompassed six states in the southwestern region: Arizona, California, Colorado, Nevada, New Mexico, and Utah. Following the update, Idaho, Montana, Oregon, Washington, and Wyoming have now been included. The approval of the revised Western Solar Plan comes after the release of a draft plan in January 2024 and a proposed plan in August 2024.  It incorporates feedback gathered from a wide range of stakeholders, including governments and various interested entities, throughout the entire process.  The suggested plan went through a 30-day public objection phase and a 60-day consistency evaluation by the governor before the BLM made the decision to approve it. Assistance with planning This initiative builds upon numerous executive actions implemented by the Biden-Harris administration aimed at streamlining and enhancing federal permitting processes to expedite the delivery of projects. According to the press release from the DOI, "The initiative aims to facilitate solar project development by pinpointing areas close to transmission lines and previously disturbed sites as suitable for project proposals, while deliberately excluding sensitive locations such as specially protected lands, areas with significant cultural resources, and crucial wildlife habitats." It also highlights that this will promote responsible development, accelerate the permitting process, and offer enhanced predictability for the solar energy sector. "In the Biden-Harris administration, the Department of the Interior (DOI) has acted decisively to respond to current challenges and foster a thriving, sustainable clean energy economy, all while safeguarding vital resources on America’s public lands. According to DOI Secretary Deb Haaland's press release, the newly revised Western Solar Plan, developed with significant public feedback, will promote the responsible expansion of solar energy throughout the West for years ahead." Dr. Steve Feldgus, the Principal Deputy Assistant Secretary for Land and Minerals Management, emphasizes, “Solar energy stands out as a cost-effective and rapidly expanding element of our nation's contemporary power infrastructure, contributing significantly to the establishment of a robust and resilient clean energy economy in the U.S. The revised Western Solar Plan aims to streamline the permitting process for solar projects, providing greater clarity for developers while retaining the necessary flexibility to address local needs and issues.” In total, the Bureau of Land Management has authorized clean energy initiatives on public lands, boasting a combined capacity exceeding 33 gigawatts, which is sufficient to supply energy for more than 15 million households.  In 2024, the Bureau of Land Management (BLM) released a definitive Renewable Energy Rule aimed at reducing energy expenses for consumers and decreasing the costs associated with the development of solar and wind initiatives. This rule also streamlines project application procedures, generates employment opportunities, and encourages developers to pursue the responsible advancement of solar and wind projects on public lands.  Resistance to the proposal Toward the end of last year, U.S. Representative Harriet Hageman (R-WY) voiced her concerns regarding the proposal, saying, “This initiative will have a detrimental effect on Wyoming, where half of our surface lands are under federal management. It restricts extensive areas for the placement of solar panels that are not environmentally friendly, which hampers our capacity to graze livestock, mine resources, or extract fossil fuels – essential activities for America to lower the expenses of energy, food, and housing.” In September 2024, Western Caucus Chairman Dan Newhouse (R-WA) and Representative Hageman, along with nine other members of the Western Caucus, sent a letter to the Bureau of Land Management (BLM) urging the agency to retract its proposed revisions to the Western Solar Plan. “The Western Solar Plan put forth by the Biden-Harris administration is yet another initiative that could harm communities throughout the West,” Newhouse asserts. “This proposal may infringe upon the multiple-use mandate for public lands as outlined by the Federal Land Policy and Management Act, jeopardizing essential grazing areas while also raising concerns.”  U.S. Representative Matt Rosendale (R-MT) has stated that the agency's proposal will restrict 572,479 acres of public land in Montana for solar energy projects, leading to numerous issues for local wildlife, the environment, and the livelihoods of Montanans. He expresses his worries by stating, “I believe that the Western Solar Plan infringes upon the Taylor Grazing Act, which governs grazing activities on public lands. Additionally, it will generate intermittent energy that will require transmission over hundreds, and in some instances, thousands of miles before it can be utilized.” Lawmakers from various Western states have raised alarms regarding the Bureau of Land Management's solar development proposals. This group includes U.S. Senators John Barrasso and Cynthia Lummis from Wyoming, Jim Risch and Mike Crapo from Idaho, Steve Daines from Montana, and Mike Lee from Utah. They are concerned that the plan could interfere with grazing rights, mineral extraction, and recreational activities. Furthermore, Frank Macchiarola, Chief Policy Officer of American Clean Power, expressed in a statement, “It is disappointing that the BLM did not establish a more equitable strategy for development and conservation. Throughout this process, the solar industry has repeatedly voiced concerns regarding the consequences of land exclusions and project design elements, which this decision fails to address in any meaningful way.” He adds, “This ultimate choice signifies a lost chance to enhance the U.S. economy and bolster our energy security and reliability by facilitating the timely approval of current and upcoming projects.” Melissa Anderson is the editor of the Wyoming Livestock Roundup.

During a hike in the Swiss Alps, he stumbled upon an unusual 20th-century wagon embedded in a receding glacier.

View pictures in App save up to 80% data. Andrew Mayovskyy - stock.adobe.com - for illustrative purposes only. In the Swiss Alps, the retreat of glaciers is revealing items that have been trapped in ice for hundreds of years. To date, archaeologists have unearthed artifacts from World War I, arrows dating back 1,300 years, and the preserved bodies of hikers who went missing long ago. In November of last year, a hiker named Sergio Veri stumbled upon what seemed to be a two-wheeled bamboo cart from the 20th century. However, archaeologists are still uncertain about its true nature. While strolling through the Splügen Pass in the Swiss Alps, close to the Switzerland-Italy border, Veri stumbled upon a peculiar device. The elevated route links Switzerland's Hinterrhein valley to Italy's Valle San Giacomo. He spotted the cart amidst the thawing Schwarzhorn Glacier. According to a social media update from the Canton of Graubünden, “The wagon-style design, featuring two wheels and crafted from bamboo sticks and laces, is estimated to be fairly recent, likely dating back to the 20th century.” The mysterious object has left specialists puzzled. Abandoned in the heights of the Alps, it is constructed from bamboo and secured with cords, a detail that stands out. However, bamboo is not indigenous to Switzerland and only made its way to Europe in the 17th and 18th centuries. Incorporating this material introduces an intriguing element that obscures the purpose and background of the object. The presence of bamboo suggests that the artisans had access to foreign resources. The Archaeological Service of Graubünden has yet to carry out a comprehensive investigation of the cart. They are reaching out to the community for assistance, inviting anyone who possesses knowledge regarding the object's function or how it was made to get in touch with them directly. Since that time, social media users have been buzzing with theories about the purpose of the bamboo structure. Some have proposed that it might have served as a cart for smuggling goods during World War I, while others believe it could be an early climbing apparatus utilized by adventurers or researchers, or perhaps even a component of a 20th-century aircraft.

Andrew Mayovskyy – stock.adobe.com – for illustrative purposes only Several commenters concurred on the wagon's utility, suggesting that it likely facilitated the movement of supplies. "Given that the wheels appear unsuitable for supporting a heavy load for an extended period, I suggest that it was an early form of a winch designed to help transport supplies uphill," one individual noted. "It's a type of pull cart, designed for a person or mule to walk ahead of it, constructed from bamboo to ensure it's lightweight for navigating mountain trails and rough landscapes," added another. The Splügen Pass boasts a rich historical background that is important to consider. During the Roman period, it functioned as a significant trade route, as evidenced by historical sources such as the Roman Tabula Peutingeriana. With glaciers around the globe melting at an accelerating pace, it's anyone's guess what discoveries archaeologists might unearth next. More About:News

In 2024, X-class solar flares reached unprecedented levels and may increase even more this year; however, experts suggest that the sun isn't solely responsible for this phenomenon.

In 2024, the occurrence of X-class solar flares reached levels not seen in over thirty years. This surge was primarily attributed to the onset of solar maximum, although various other influences contributed to this increase as well. View pictures in App save up to 80% data. In 2024, the sun entered its most intense period known as solar maximum, resulting in a remarkable surge of powerful X-class flares erupting from our star. The number of X-class solar flares — the most powerful and potentially dangerous class of solar eruption — hit a new record high in 2024. The spike highlights that we are currently experiencing a surprisingly active solar maximum, which could continue to intensify this year. However, experts informed Live Science that solar activity might not be the sole factor contributing to the dramatic increase in the number of supercharged solar explosions observed last year. There were a total of 54 X-class flares in 2024, according to SpaceWeatherLive.com, which maintains the oldest and most accurate publicly available dataset on solar flares. That is the highest total since at least 1996, when this dataset began. NASA has been tracking solar flare activity since the mid-1970s, but earlier data has not been made publicly available and is less reliable than modern records, SpaceWeatherLive.com representatives told Live Science in an email. The former highest count of X-class flares in the dataset stood at 34, noted in 2001. Additionally, there were only four other years — 2000, 2003, 2005, and 2014 — when the annual total exceeded 20. Thus, the total from last year signifies an unexpectedly significant increase in the occurrence of X-class flares. View pictures in App save up to 80% data. On October 3, 2024, a powerful X9 magnitude solar flare — the strongest of the ongoing solar cycle — erupted from the sun, sending a coronal mass ejection (CME) hurtling straight toward Earth. The effects of the more frequent X-class flares were widely felt on Earth in 2024. For example, in May, a quickfire succession of at least four X-class flares launched clouds of plasma, known as coronal mass ejections (CMEs), that slammed into Earth and sparked the strongest geomagnetic storm in 21 years, which in turn triggered some of the most vibrant and widespread aurora displays in our skies over the last 500 years. What caused the significant increase in X-class flares last year? Heightened solar activity The obvious reason for the increased frequency is the arrival of solar maximum. This peak in the sun's roughly 11-year cycle of activity, which is triggered by the weakening and eventual flipping of the sun's magnetic field, has been surprisingly active so far and is expected to continue well into 2025 and possibly beyond. In October 2024, scientists from NASA and the international Solar Cycle Prediction Panel (SCPP) announced that we have entered solar maximum and that the explosive peak likely started early last year, which was sooner than they had initially predicted. The ongoing maximum has also proved to be more active than most scientists had initially forecast. For example, in August, the number of visible sunspots on our home star, which is a key metric for monitoring solar activity, reached a 23-year high. View pictures in App save up to 80% data. In August, the count of visible sunspots on the solar surface reached its highest level in 23 years. This timelapse image illustrates the movement of these sunspots as they traversed the sun's near side. But the number of X-class flares has been the biggest shock for most solar physicists. "I think we have all been surprised [about the number of flares]," Hugh Hudson, a solar physicist at the University of Glasgow in the U.K., told Live Science. Certain researchers, such as Hudson, contend that the rise in X-class flares can be exclusively linked to heightened activity during the solar maximum phase. Conversely, other specialists argue that while the sun's peak has certainly contributed significantly to this increase, it is not the sole factor. These experts suggest that the unprecedented number of recorded X-class flares is also a result of advancements in our detection methods, which may be skewing the overall assessment. Identifying solar flares Most X-class flares are pretty hard to miss, Scott McIntosh, a solar physicist and vice president of the new space weather solutions company Lynker Space, told Live Science. "These events are so massive they kinda smack you in the face," he said. Nevertheless, McIntosh noted that we are unable to observe all of them. For starters, we can only properly see solar flares on the side of the sun facing Earth, although some farside explosions are so massive that we can still see the gigantic CMEs they hurl into space. This doesn't change much because we have only ever been able to see the sun's nearside eruptions. But it can also be hard to spot and properly measure solar flares around the edge of the sun's limbs because we cannot always see them properly. According to McIntosh, this suggests that we may have historically overlooked as much as an additional 15% of the sun's X-class flares. In recent decades, researchers have deployed a number of advanced spacecraft designed to observe the sun, which have likely improved their ability to detect certain flares that may have gone unnoticed in the past, according to McIntosh. "These new tools have revealed the frequency of events that have been directed away from our planet," he noted. There is a possibility that we may have overlooked some X-class flares in the past that were on the borderline between being classified as X-class and M-class, which is the second-highest category for solar flares.

Carl Shneider, a space systems scientist at the University of Luxembourg and an advisor at private space weather forecasting company Mission Space, also believes that we are getting better at spotting X-class flares. "Advances in science and technology are continuously improving our ability to monitor solar activity and its impact on Earth's environment," Shneider told Live Science. "Every new mission, observational point, numerical model or theory improves our understanding." Nonetheless, these advancements can serve as a double-edged sword, as Shneider pointed out, "this progress complicates direct comparisons between contemporary data and historical observations." However, not everyone shares this belief. Hudson, a researcher with decades of experience in studying solar flares, asserts that "the guidelines [for identifying X-class flares] remain unchanged" and claims that we have probably overlooked "none" of these eruptions in the past several solar cycles. Will there be additional content in the future? The solar maximum is anticipated to persist until at least 2025, and possibly extend into 2026; however, its conclusion will only be determined in hindsight. Typically regarded as the most dynamic period of the solar cycle, solar maximum can still see elevated flare activity for several months or even years following its peak. New research also suggests that solar activity can peak a few years after solar maximum, during a period when different parts of the sun's magnetic field vie for dominance, which some researchers have dubbed the "battle zone." View pictures in App save up to 80% data. In 2025, there is a significant possibility that we will witness an increase in both the intensity and frequency of X-class solar flares. "I believe the record will keep expanding in the coming years," said McIntosh, a key advocate for the battle zone concept. Nonetheless, he noted, "it's hard to predict for sure." Shneider is of the opinion that we have yet to reach the maximum level of solar activity, stating, "The occurrence of these events may continue to be elevated for a number of additional years." 2025 has already started strong with three X-class flares in the first four days of the year, according to SpaceWeatherLive.com. It is also possible that we could see much more powerful X-class flares in the coming years. The most powerful flare of the current solar cycle was an X9 magnitude blast on Oct. 3, 2024. But during the last two solar cycles, there have been 14 different X-class flares with a higher magnitude, despite flares being less frequent at the time. Hudson remarked that a rise in frequency doesn't ensure the occurrence of stronger flares. "However, I find it strange that we haven't observed more intense flares so far," he noted.

The Earth's Mantle is Much More Active and Unpredictable Than We Previously Believed

The Earth's mantle is more than merely a hot and dense rock layer; it serves as a vibrant and complex engine that propels the geological processes of our planet. A lot of individuals picture the Earth as having a neat and organized structure comprised of distinct layers: a thin crust on the outside, a thick mantle beneath it, and a core at the center. However, what exists beneath the surface is a far more intricate and active environment than this oversimplified depiction suggests. Recent studies employing advanced Full-Waveform Inversion (FWI) technology have uncovered that the Earth’s mantle — an enormous layer extending nearly 2,900 kilometers deep — is a tumultuous and diverse amalgam of structures, calling into question long-held beliefs regarding its makeup and dynamics. View pictures in App save up to 80% data. Positive and negative anomalies found within the mantle. Image source: Nature. The Earth’s mantle, a massive layer of rock beneath the crust, is the “engine” of plate tectonics. Stretching nearly 2,900 kilometers deep, it shapes much of the planet’s geology and evolution. But the problem is we can’t really see the mantle or dig to it. Instead, much of what we know about the mantle (and the deeper areas) comes from seismology. Seismology studies the Earth’s interior by analyzing how seismic waves, generated by earthquakes or artificial sources, travel through its layers. When these waves encounter changes in material properties — such as differences in temperature, density, or composition — they change speed, direction, or type. By measuring these changes at seismic stations on the surface, scientists can map anomalies in the mantle, like faster wave speeds indicating colder, denser materials, or slower speeds suggesting hotter or less dense areas. Seismic tomography, an important technique, uses these measurements to create 3D models of the mantle. This reveals its hidden structures and helps us to understand its dynamic processes. But seismic tomography has its own limitations. A recent study employing Full-Waveform Inversion (FWI) has redefined what we know about the mantle, revealing intricate structures previously undetectable by conventional methods. An undiscovered realm hidden beneath the Earth's surface Plate tectonics is the theory that underlies modern geology. It basically states that Earth’s outer shell, or lithosphere, is divided into large, rigid plates that float and move on the semi-fluid layer beneath, called the asthenosphere. These plates interact at their boundaries in three main ways: they converge, causing subduction or mountain formation; they diverge, creating new crust at mid-ocean ridges; or they slide past each other along transform faults. When two tectonic plates come together, the denser plate is forced down beneath the lighter one, leading to subduction. This denser plate then descends into the mantle below. View pictures in App save up to 80% data. Illustration of subduction. Image sourced from Wiki Commons. Traditionally, positive seismic wave speed anomalies in the mantle were attributed to “cold slabs” — remnants of subducted tectonic plates. Essentially, seismic wave speed anomalies in the mantle have long been considered the “footprints” of such plates. But the new study found that many of these anomalies do not spatially correlate with known subduction zones. In fact, it found that just 60–70% of subduction zones align with positive anomalies. “According to Thomas Schouten, the lead author and a PhD candidate at the Geological Institute of ETH Zurich, it seems that these zones in the Earth’s mantle are far more common than we had earlier believed.” It’s unlikely that we’ve missed any big subduction zones, so instead, this suggests that the wave speed anomalies could have a different cause. The researchers suggest that these anomalies could also be caused by compositional differences, not just temperature variations. For example, anomalies might stem from the presence of chemically distinct materials like basalt-rich rocks or delaminated lithosphere. For example, areas abundant in basalt, which are remnants of old oceanic crust, demonstrate increased wave velocities because of the development of dense minerals such as garnet and bridgmanite under high-pressure conditions.

The advanced capabilities of Full Waveform Inversion (FWI) arise from its proficiency in simulating complete seismic wavefields, which encompass reflected, refracted, and scattered waves, rather than merely focusing on travel times. This method greatly improves resolution, especially in areas where seismic station coverage is sparse. In contrast to conventional models, FWI is adept at detecting fine variations and smaller-scale geological features. One of the challenges associated with FWI is its significant computational requirements, which necessitate the use of sophisticated algorithms and GPU-accelerated simulations to process the data effectively. However, recent developments have yielded impressive outcomes: anomalies that previous models either missed or misrepresented are now distinctly observable. The REVEAL model, developed through FWI, represents the most comprehensive depiction of the Earth's mantle achieved so far. The implications are substantial. Past models of tectonic history often relied on the correlation between mantle anomalies and subduction zones. With these processes affecting everything from volcanoes and earthquakes to mountain formation, figuring out what exactly is causing these anomalies would substantially improve our understanding of the Earth. However, at this moment, we remain unaware of it.  "That's the challenge we're facing. The new high-resolution model allows us to detect anomalies throughout the Earth's mantle, but we're still uncertain about their nature or the materials responsible for the patterns we've discovered," Schouten remarked. The researchers believe that the anomalies may not stem from a single source, but rather from a combination of various materials and processes. “We think that the anomalies in the lower mantle have a variety of origins,” says Schouten. “It could be either ancient, silica-rich material that has been there since the formation of the mantle about 4 billion years ago and has survived despite the convective movements in the mantle, or zones where iron-rich rocks accumulate as a consequence of these mantle movements over billions of years” he notes. Questioning established beliefs This research questions established beliefs and paves the way for a more detailed understanding of the dynamics within the Earth's interior. It hints at a complex and diverse mantle, richer and more varied and we thought. However, the method’s dependency on seismic data distribution means that some regions, particularly below stable plate interiors, remain underexplored. Furthermore, the results should be confirmed by other studies before we start rewriting the geology books. Integrating FWI with other geophysical and geochemical tools could provide a more comprehensive understanding of mantle dynamics. For example, combining seismic data with mineral physics experiments could help decode the exact composition of high-wave-speed anomalies, distinguishing between thermal and chemical contributions. The study was published in Nature.

Novel Method Integrates Theoretical Principles with Experimental Investigations of Proton Structure

An artist's illustration of the inside of a proton. In the realm of quantum chromodynamics, the fundamental quarks are categorized into three distinct "colors," while they also possess up and down "flavors." The image additionally features virtual pairs of quarks and antiquarks, as well as the gluons responsible for holding the quarks tightly together. The Field of Science Newswise — Protons and other subatomic particles that are subject to the strong nuclear force have a complex structure that involves even more fundamental constituents called quarks and gluons. These quarks and gluons bind under the influence of quantum chromodynamics (QCD). QCD is the theory of strong interaction of quarks and the role of color symmetry. However, the mechanisms that lead to quarks and gluons combining to form the particles we see in nature are very mysterious and poorly understood. For example, virtual quarks and gluons constantly appear and disappear within our current picture of the dynamics in the proton. So, which quarks and gluons are actually “in” a proton is a difficult question to answer.  A major part of QCD research is driven by the goal of solving open fundamental questions at the heart of how QCD operates and how quantum mechanical theories can be merged with the theory of relativity. Recent progress in theoretical QCD has opened the way to connecting questions about the structure of particles like the proton with high-energy particle collision measurements. The Effect As theorists generate new ideas about QCD, other researchers plan experiments to test those ideas. These tests involve colliding particles like electrons and protons at high energies and then examining the results. By extrapolating backwards in time, physicists will use the remnants of the collisions to infer information about the structure of the original particles. However, the same theoretical difficulties that motivated these studies have left a key question unresolved. Namely, how do scientists relate the physics of the specific collisions with the physics of the internal structure of the particles themselves? The recent work provides the toolbox needed to resolve this question while also accounting for the theoretical subtleties. Overview Much of the experimental work related to extracting the quark and gluon structure of protons occurs at existing particle accelerators like the Thomas Jefferson National Accelerator Facility and the Relativistic Heavy Ion Collider, and in the future at the Electron Ion Collider. A large part of current research into the structure of the proton, both theoretical and experimental, involves identifying, extracting, and analyzing the bound state distributions of quarks and gluons in the proton, mapping out their motion, and understanding how this relates to the overall observed properties of the proton like its spin and mass. In the past, researchers found inconsistencies in the way physicists combined fundamental QCD theory to the study of data. The new theoretical results provide a clear recipe and boost confidence that data taken in future experiments can be reliably interpreted. Financial Support This research received funding from the Department of Energy (DOE) Office of Science, specifically the Office of Nuclear Physics. Additional support came from the DOE contract that enables Jefferson Science Associates, LLC to manage the Thomas Jefferson National Accelerator Facility. Furthermore, funding was provided by the European Union's Horizon 2020 program for research and innovation.

Exploring Cancer Immunotherapy: Understanding the Mechanisms of Therapeutic Antibodies

View pictures in App save up to 80% data. In the field of medical research, an innovative advancement has emerged from the University of Würzburg's laboratories in Bavaria, Germany. The study led by Professor Markus Sauer and his team represents a significant progression in the comprehension and creation of therapeutic antibodies. This research sheds light on the complex interactions between antibodies and their target molecules, especially in relation to B cells linked to blood cancers, including chronic lymphocytic leukaemia. The research team has pioneered a cutting-edge super-resolution microscopy method called LLS-TDI-DNA-PAINT, which enables real-time visualization of therapeutic antibodies attaching to target proteins on cancer cells in three-dimensional space, achieving an unprecedented level of detail and precision. For many years, immunotherapeutic antibodies have played a crucial role in the treatment of different types of tumors. A key focus of these therapies is the CD20 protein found on the surface of B cells. The binding of these antibodies to CD20 triggers a series of immune responses that ultimately result in the elimination of cancerous cells. Nonetheless, even with the proven effectiveness of these antibodies in clinical settings, scientists have struggled to fully understand how they bind and the cellular responses that follow. Recent groundbreaking research from Würzburg has made significant strides in addressing this knowledge gap. Using the LLS-TDI-DNA-PAINT method, scientists successfully observed the real-time dynamics of therapeutic antibodies. They examined the interaction between these antibodies and CD20 molecules, focusing on how this binding affects the structural behavior of B cells during the process. A significant finding from the study was the observation of a phenotypic change in B cells, which the researchers referred to as adopting a “hedgehog shape.” This alteration occurs due to the crosslinking of CD20 proteins by the antibodies, which activates complement systems and enhances targeted immune responses. The researchers performed their observations utilizing the Raji B cell line, which is derived from human Burkitt's lymphoma and is well-regarded for its significance in cancer research. This specific cell line acts as a model for evaluating B cell responses to therapeutic antibodies. The research team executed experiments with four different therapeutic antibodies: RTX, OFA, OBZ, and 2H7, all of which are recognized for their targeting of CD20. The findings from their studies indicated that, irrespective of the antibody type used—whether categorized as type I or II—the response mechanism was remarkably similar, challenging earlier beliefs held by the scientific community. Additionally, research has demonstrated that therapeutic antibodies primarily bind to specific areas of the B cell membrane, particularly at microvilli. These tiny projections serve as crucial sites for protein interactions and contribute to the overall stability of the B cell surface during therapeutic applications. The noted polarization of B cells, alongside the reinforcement of microvilli, supports the idea that the structure of the cell membrane significantly influences immune responses. These insights not only clarify the processes involved in antibody binding but also suggest opportunities for enhancing therapeutic approaches by adjusting these interactions. An additional noteworthy feature of this research is the possible role of hedgehog-shaped B cells in enhancing inter-cellular communication within the immune system. The scientists suggest that this change in shape could be crucial for the development of immunological synapses, encouraging B cells to interact with macrophages and natural killer cells. This hypothesis expands on existing knowledge and highlights the urgent need for more investigations into how these activated B cells contribute to the coordination of larger immune responses. The introduction of the LLS-TDI-DNA-PAINT method marks a significant advancement in our ability to investigate therapeutic mechanisms at the molecular scale. This innovative technique lays the groundwork for future research focused on understanding the intricacies of cell-surface interactions and the complex processes that underpin immune recognition and the elimination of cancer cells. With this state-of-the-art visualization technology, scientists are empowered to examine the subtle nuances of antibody binding dynamics, creating an exceptional foundation for the development of tailored immunotherapy strategies. As the research advances, the team at the University of Würzburg aims to explore further the potential impacts of their discoveries on the future of antibody-driven cancer treatments. Thanks to the breakthroughs achieved with the LLS-TDI-DNA-PAINT method, there is an encouraging outlook where therapeutic antibodies can be customized and developed by directly analyzing their behavior within the tumor microenvironment. In conclusion, this pivotal study from Würzburg not only disputes current models in the therapeutic antibody sector but also highlights the transformative potential of advanced microscopy methods in reshaping our comprehension of cancer biology. As scientists persist in their investigations, the optimism for better therapeutic approaches and enhanced patient results is strong, serving as a source of inspiration in the relentless fight against blood cancers and other related diseases.

Elon Unleashes Cybertrucks, Combines Forces from SpaceX and Tesla for Humanitarian Mission in LA/Malibu

On November 21, 2019, Elon Musk, the co-founder and CEO of Tesla, showcased the newly revealed all-electric, battery-powered Cybertruck at the Tesla Design Center located in Hawthorne, California. (Frederic J. Brown - AFP / Getty Images) Elon Musk revealed that both Tesla and SpaceX have allocated resources and staff to assist those affected by the fires in Los Angeles, as residents are forced to evacuate and face the loss of their homes. Musk shared on Sunday evening via X that Tesla and SpaceX staffers are “driving around areas in greater LA/Malibu that are in tough shape with free WiFi, drinks & snacks.” Tesla & SpaceX personnel are driving around areas in greater LA/Malibu that are in tough shape with free WiFi, drinks & snacks https://t.co/304vjlXSoc — Elon Musk (@elonmusk) January 13, 2025 He shared a post from Tesla that outlined a “summary of initiatives” undertaken by the electric vehicle company to assist both its employees and the wider community. Those endeavors proved to be remarkably extensive. Tesla is providing housing accommodations, transportation, and meals for employees who had their homes “lost or destroyed” amid the historic fires. The company successfully restored all Supercharger locations to operation, with the exception of the Pasadena Supercharger, which was situated in the heart of the fire. Beyond those responses, Tesla deployed two Megapack Chargers, which are essentially massive energy storage units that help with grid reliability, on Friday to “relieve congestion in Thousand Oaks for evacuation & families losing power due to Public Safety Power Shutoffs.” The company deployed another unit the next day to Altadena “for first responder support, providing power & Starlink connectivity.” Tesla has dispatched an additional two Megapack Chargers to San Bernardino and is in the process of installing more in the Palisades, the areas that suffered the greatest damage from the recent fires. Mobile Powerwall Units have been set up in Altadena and Topanga Canyon with assistance from various nonprofit organizations to supply power for devices and refrigerators. Additionally, several Cybertrucks equipped with Starlink are stationed across the city, including in Altadena, Pasadena, Zuma Beach, and Malibu. The Cybertrucks are equipped with compartments filled with water and snacks. To put it differently, Tesla, SpaceX, and Musk have made significant efforts to support not just their employees, but also the entire community. Musk did the same after hurricanes destroyed large parts of the southeastern United States a few months back. However, the initiatives in California proceed in spite of some lingering tensions with the state's Democratic leadership. In November, California's Democratic Governor Gavin Newsom unveiled a proposal to provide rebates for electric vehicles, excluding Teslas. This decision has faced significant criticism, with many viewing it as a form of political revenge against a billionaire adversary who has recently allied with the Republican Party. Musk called the exclusion of Tesla “insane,” especially because the company is the only car producer to make electric vehicles in the Golden State, according to a report from the New York Post. In summary, while California's leaders chose to distance themselves from Musk, he remained loyal to the state. Even as Newsom whines about his enemies politicizing the fires, Musk going out of his way to help the state is about as unpolitical a move as he possibly could have made.

A UCLA study uncovers new insights into how neurons play a role in memory systems.

A new study conducted by researchers at UCLA sheds light on how the brain interprets sequences of experiences, potentially paving the way for advancements in the treatment of specific memory disorders. A study released in September investigates the brain's method of encoding intricate sequences of events. According to Pawel Tacikowski, the lead author and a former project scientist at UCLA, researchers found remarkable parallels between the brain's representation of spatial environments and the temporal patterns of these events. Tacikowski and his fellow researchers focused on the hippocampus – a brain structure through which all external information has to go to be stored as memory – in the study. The research focused on individual neurons, which are the cells in the nervous system responsible for transmitting electrical signals, according to Tacikowski. He explained that the team was able to conduct this analysis because the participants in the study were epilepsy patients who had already undergone the implantation of electrodes in their brains for medical purposes. According to psychology professor Barbara Knowlton, this technique enabled researchers to observe individual neurons as they engaged in the learning process. These neurons, referred to as concept cells, were previously discovered by the Fried laboratory to activate in response to an image or idea of an individual, according to Knowlton. The study participants were then presented with a particular series of images, according to Guldamla Kalender, one of the co-authors of the research. The sequence in which images were shown to the participants of the study was not arbitrary. According to Tacikowski, it was based on a particular graph, and the researchers discovered that they could recreate the relationships depicted in this graph by analyzing the firing patterns of the associated neurons. Ueli Rutishauser, a professor specializing in neurosurgery, neurology, and biomedical sciences at Cedars-Sinai Medical Center, stated that although the participants were unaware of any patterns in the sequence of images presented to them, their brains had already encoded these graph relationships. Jesse Rissman, a professor of psychology, psychiatry, and biobehavioral sciences, noted that the memory of the series of images became more robust during the participants' breaks. He explained that during these moments of rest, the brain would revisit the sequence associated with the learning experience. According to Rissman, this highlighted a similarity in the brain's processing of temporal and spatial information. It was already established that the brain revisits locations to memorize spatial details, and this study revealed that a similar pattern occurs when learning the order of events over time, he noted. According to Rissman, a key role of a memory system is its ability to forecast future events. "We frequently encounter scenarios where we can rely on our previous experiences to forecast potential outcomes," Rissman explained. "This ability enables us to make informed decisions in our lives, shaping our actions according to our anticipations." Dr. Itzhak Fried, the corresponding author of the paper and a professor of neurosurgery, stated that while this research focused on individuals with epilepsy, the findings are expected to be applicable to those without epilepsy as well, given that they have been supported by animal studies and fMRI results. Tacikowski stated that in the future, insights into how the brain initially establishes the temporal framework of experiences could aid in comprehending the preservation of the cognitive map and its decline in conditions such as dementia. Alan Castel, a psychology professor, emphasized the significance of studying memory, noting that it can influence both the treatment of memory disorders and the enhancement of memory capabilities. "As we age, it's common for us to forget certain things, which may indicate a breakdown in these systems," he remarked. Dr. Fried mentioned that the team aims to create a neuroprosthetic system designed to improve memory, potentially benefiting patients experiencing memory difficulties. “One of our primary objectives is to create, in essence, what I refer to as a memory support tool – similar to how a hearing aid functions,” he stated.

In recent times, we have observed a significant advancement in spatial biology that combines traditional approaches such as immunohistochemistry with cutting-edge high-throughput technologies like transcriptomics and proteomics. Although RNA analysis has long been a standard practice, high-plex proteomics is rapidly gaining traction. This development is crucial since proteins are fundamental to biological functions and provide valuable insights into tissue structure that RNA data alone cannot reveal. Some notable examples include: Understanding how cancer cells interact with their surroundings Studying how the immune system functions in different tissues Developing new drugs that target specific cell types and interactions Up until now, spatial biology has primarily depended on individual omics methods such as transcriptomics or high-plex proteomics. However, emerging platforms are facilitating multiomics analysis, which encompasses high-plex transcriptomics alongside a limited number of proteins, as well as high-plex protein panels that concentrate on specific RNA. These innovations hold the promise to transform scientific exploration and clinical applications alike. The potential of spatial biology may reside in the integration of various techniques, enabling scientists to acquire a holistic view of gene and protein expression in a tissue sample, thereby offering the most intricate insights into cellular mechanisms. However, the advancements continue beyond that. Techniques like light sheet microscopy contribute to the spatial biology domain, enabling us to examine intricate 3D samples, including entire mouse models, with remarkable clarity. Whether you're analyzing the elaborate 3D structure of your sample, investigating the intricate interactions between proteins and RNA, or integrating these methodologies, Miltenyi Biotec provides comprehensive workflow solutions, supplying dependable reagents, cutting-edge instruments, and software.

NASA's Metallic Spheres: The Unexpected Briefing That Went Under the Radar

View pictures in App save up to 80% data. On July 1, 2023, a Pentagon official at NASA headquarters calmly stated, ‘We see these metallic spheres all over the world, making maneuvers we can’t explain…moving at Mach 2 against the wind, with no apparent propulsion.” During a briefing where the Pentagon and NASA presented their findings after a year of research, a government scientist spoke about objects that challenge the fundamental principles of physics. This should have dominated the headlines. Yet, it scarcely registered in the mainstream media. NASA’s Briefing: Key Details & Quotes You can watch the entire briefing here on Youtube. All of the quotes that I am using will be time-stamped, when possible. Dr. Sean Kirkpatrick, the head of the Pentagon's All-domain Anomaly Resolution Office (AARO), was straightforward and direct in his approach. Showing a video of a metallic sphere captured by military sensors, he stated matter-of-factly: “This is a typical example of the thing that we see most of… Then came the kicker that should have sent shockwaves through the scientific community: “We see these all over the world, and we see these making very interesting apparent maneuvers.” [36:12–36:29] Hold on...what did you just say? Here is a top government official, speaking at NASA headquarters, describing something that defied our understanding of physics: metallic spheres — as he clearly said in an example — “moving at Mach 2 against the wind with no apparent propulsion.” [1:03:41–1:03:55] That’s twice the speed of sound. Into the wind. With no visible engines. Dr. Kirkpatrick noted that they now have over 800 cases, [54:51–55:06] and that of these cases.- “The numbers I would say that we see are possibly really anomalous are less than single digit percentages… maybe two to five-ish percent.” While it may seem like a limited figure, there are still approximately 20 to 40 unusual instances involving metallic spheres, many comparable in size to small cars, capable of moving at impressive speeds without any visible method of propulsion. Investigating the Spheres This image was included in a presentation that was shared during the public briefing. Size: About as big as a small car (3–13 feet across) Altitude: Flying in the same airspace as commercial planes (10,000–30,000 feet) Appearance: Metallic, spherical, solid Movement: Could hover motionless, then accelerate to incredible speeds Technology: No visible engines, no heat signature, no exhaust Here’s what makes this truly strange. They are admitting that these objects, which by all laws of physics known to humans, shouldn’t be able to fly…are able to hover, and then accelerate to speeds up to Mach 2. Picture a fighter jet from Top Gun, suspended quietly in the air, before it suddenly bursts into action, soaring to its maximum velocity. Devoid of any engines. Again — “We see these all over the world,” Kirkpatrick said. Notice his choice of words: “We see these.” Present tense. Not “We saw these once” or “Someone reported seeing these.” [36:16–36:29] He’s talking about an occurrence that takes place regularly and consistently across the entire world. The Rational QuandaryAre we possibly observing technology that is not of human origin? Occam's Razor suggests that the most straightforward and elegant explanation is often the one that aligns most closely with reality. When unusual phenomena show up in our skies, it's only logical to seek straightforward explanations. Let's take a cue from NASA's experts and analyze each potential cause with a balanced yet discerning perspective. Could these be conventional aircraft? No. They need huge engines to fly. Natural phenomena? No. NASA’s Dr. Fox emphasized, they’re dealing with solid objects showing “signatures that could be anomalous.” That’s scientist-speak for “things that shouldn’t be able to do what they’re doing.” Secret military technology? This is what some people hope it could be. But no country would test their most advanced tech over other nations’ sensitive facilities. And, even more important, these orbs have been appearing for decades. No one had anything close to this kind of technology 40 years ago. The Topic Everyone Avoids Talking About This leads us to a topic that many scientists find challenging to address: technology created by non-human entities. This is where the discussion becomes captivating. This hypothesis aligns perfectly with all the available evidence: Advanced technology beyond our current capabilities? Check. Global presence? Check. Consistent characteristics over decades? Check. Ability to operate without conventional propulsion? Check. Is this a satisfying conclusion? No. Does the technological evidence support it? Yes. A Concise Historical Overview What makes NASA's ongoing research particularly intriguing is that these metallic spheres are not a recent discovery. They align with a series of observations that have been recorded over many years: WWII pilots called them “foo fighters” Navy crews tracked them underwater in the 1950s Commercial pilots have quietly reported them for years The same traits continue to emerge: Metallic spheres Impossible maneuvers No visible propulsion Strategic locations Apparent intelligence Reaching this conclusion isn't easy. As I examine the facts, I can't help but feel, “This isn't as enjoyable as I anticipated. The possibility of non-human technology existing is somewhat…alarming.” I have always been fascinated by the concept of "non-human technology." If it turns out to be real, it could fundamentally alter our perception of reality. It's as though all those hypothetical "what if" discussions have suddenly transformed into reality. This is no longer just a fringe rumor or a conspiracy theory; it has now become verified information regarding objects performing the unimaginable in our atmosphere. When NASA verifies the presence of anomalies such as these metallic orbs worldwide, it leads to significant changes. What are our next steps from this point? So what are NASA's next steps? Dr. Spergel, former head of Princeton’s astrophysics department, emphasized the necessity for improved data. He highlighted the need for additional sensors and more stringent data collection techniques if we are to find the answers we seek. In the meantime, Dr. Nicola Fox acknowledged that researchers investigating these phenomena encounter significant harassment, which exacerbates the existing stigma. It’s disheartening, especially when leading experts are candidly stating, “We observe anomalies that elude explanation,” yet the public discourse continues to be mired in outdated skepticism. To me, this presents a chance to investigate these observations with a new perspective, unburdened by the typical mockery. Should NASA's findings indicate that advanced technologies beyond our current capabilities could have existed in the past, it suggests that some of the ancient technological enigmas may not be as puzzling as the various contradicting theories suggest. While it may seem like a bold conclusion, it's worth noting that NASA's revelations regarding extraordinary flight maneuvers were similarly groundbreaking. The Design I’ve spent the past few months investigating this connection between NASA’s modern metallic orbs and historical technological anomalies. The pattern that emerged was so compelling that I’ve documented it in my upcoming book “The Design: from ‘Drones’ to NASA’s Orbs to Ancient History.” [Link if interested in checking it out] From the meticulous construction of Puma Punku in Bolivia to the enigmatic wisdom found in ancient locations, we are uncovering signs of technological disparities that appeared in the past...similar to the mysterious metallic orbs we encounter today. By leveraging NASA's latest observations as a basis, we can now explore these historical enigmas from a fresh perspective. If these insights have struck you as enlightening (or even unsettling) like they did for me, there are multiple ways you can stay updated on this investigation: Check out the book to explore the full pattern [link] Follow me here on Medium for regular updates Share this article if you think others should know about NASA’s overlooked briefing At this stage, I prefer to remain open-minded rather than overlook what might turn out to be the most significant narrative of our era.

Energy Freedom Technologies is Increasing Awareness About Portals

Sign up with your email to receive Benzinga's comprehensive morning update: The PreMarket Activity Newsletter. View pictures in App save up to 80% data. And the ways in which they could be affecting your surroundings. AUSTIN, Texas, Jan. 10, 2025 /PRNewswire/ -- What is a portal, and do they exist beyond science fiction? Energy Freedom Technologies conducts research and experiments with portals and shares that a portal is an energetic gateway that can move between and sometimes through dimensions. "Portals allow energies to come into and/or out of space," said Energy Freedom Technologies founder Nicole Cobb Edwards. "For example, a one-way portal pulling energy out of a space may be sucking the health and happiness out of the environment and you may even notice physical items go missing like remotes, keys, and other personal objects. There are also portals that are one-way in the other direction meaning they are inputting energy into a space. Sometimes these portals are inputting confusion energy, and it is also very common for them to bring in entities. The most common portals I experience are two-way portals that have energies coming in and out. Most of these portals are not conductive to a harmonious environment so I find it supportive to acknowledge them and often close portals for clients that prefer more harmony in their space." Subtle energies accumulated in some areas cause an anomaly in the space-time continuum, opening portals into other dimensions. Sometimes the gateway into another dimension results in the appearance of interesting creatures and forces. In the book Merging Dimensions, authors Tom Dongo and Linda Bradshaw describe research conducted on the Bradshaw Ranch in Sedona, Arizona. Detailed studies verified a series of interesting events on the Ranch and throughout Sedona, continuing over many years. Often, portals can create more subtle disturbances in the environment. Dr. Claude Swanson's Synchronized Universe Model explains the science of how this may happen. Parallel dimensions differ from our current reality by a shift of frequency and phase.  They can be co-located with us and yet not detected, until something causes a shift in the fundamental frequency of our "reality" so it matches theirs. Subtle energy, which accumulates in certain spaces and environments, has precisely this effect. In doing so it opens portals into parallel dimensions. Do you or a loved one avoid a certain area of your home or property? Is there a room in your home that feels draining and heavy? Is there a room in your home that feels highly energized, and it's challenging to relax or sleep in there? Have you noticed things go missing in a specific room or area on your property? If you answered yes to any of these questions, it's possible that there is a portal in your space.
