Research from Toronto’s Baycrest Hospital indicates that **birdwatching** significantly enhances cognitive abilities and overall brain function.
According to their latest findings, skills such as keen observation, prolonged attention, and robust memory are linked to extensive use of binoculars. Notably, these abilities can fundamentally reorganize brain structure, leading to enhanced cognition.
Published in the Journal of Neuroscience, the study involved a comparison of brain structures in 29 expert birdwatchers and 29 novices, with balanced gender and age distribution.
Brain scans demonstrated that expert birdwatchers possess more compact areas related to attention and perception, which enhances their bird identification skills.
Interestingly, the mobility of water molecules in these brain regions is enhanced, improving the birdwatchers’ ability to discern unfamiliar or local bird species.
While various learning experiences, such as picking up a new instrument or language, are beneficial for brain health, this study emphasizes that birdwatching’s complexity offers unique cognitive advantages.
“What’s notable about this research is that birdwatching engages ongoing perception, attention, and memory, preventing a state of cognitive autopilot,” explained Professor Martin Sliwinski to BBC Science Focus. Sliwinski, who was not part of the study, serves as director at Penn State’s Center on Healthy Aging.
“To have cognitive benefits, a stimulating activity must remain challenging, which holds true for birdwatching,” he added.
“Even experienced birders cannot depend on automatic responses due to the ever-changing environment and cues, often experienced under conditions of uncertainty and time constraints.”
Moreover, researchers suggest that these enhanced skills and accompanying brain changes could bolster cognition in older adults, as older birdwatchers in the study demonstrated superior facial recognition and recall abilities compared to novices.
However, Sliwinski noted that other influences may also play a role, stating, “Individuals with higher cognitive capabilities and an interest in birds may be more predisposed to take up birdwatching and progress to experts.”
In essence, it’s possible that rather than birdwatching directly sharpening cognitive function, those with existing cognitive strengths are naturally inclined to pursue this engaging hobby.
Incorporating one avocado and one cup of mango into your daily diet can significantly enhance vascular health indicators and lower crucial cardiometabolic risk factors, particularly in individuals with elevated blood sugar levels. This indicates that making simple dietary changes can promote heart health even before the onset of diabetes.

The prevalence of type 2 diabetes and prediabetes is rapidly increasing.
Over one-third of the U.S. population is affected by prediabetes, with approximately 80% of adults unaware they have diabetes.
Prediabetes is defined by elevated blood sugar levels that fall below the diagnostic criteria for type 2 diabetes, accompanied by hyperinsulinemia due to insulin resistance.
Individuals with prediabetes face an elevated risk of developing type 2 diabetes and may experience complications such as endothelial dysfunction, contributing to both macrovascular and microvascular diseases.
Currently, prevention remains the most effective and economical strategy and is a key focus in public health.
A recent study led by Professor Britt Barton Freeman from the Illinois Institute of Technology instructed adults with prediabetes to adhere to an avocado-mango (AM) diet, incorporating one medium Hass avocado and one cup of fresh mango each day for eight weeks.
A calorie-matched control group consumed a similar diet, substituting avocado and mango with equivalent carbohydrate-based foods.
The AM diet group displayed substantial improvements in blood vessel function, which is essential for healthy circulation, and reductions in diastolic blood pressure—a vital factor for long-term heart health—compared to the control group.
Participants on the AM diet demonstrated significant enhancements in vascular function.
Flow-mediated dilation (FMD), a crucial indicator of endothelial function (blood vessel health), rose to 6.7% for those on the AM diet, contrasting with a decline to 4.6% in the control group, indicating a notable improvement.
Moreover, diastolic blood pressure showed significant improvement, particularly in men.
Men in the control group experienced an average central blood pressure increase of 5 points (mmHg), while those on the AM diet enjoyed a decrease of about 1.9 points, a difference that may become clinically relevant if maintained.
These benefits were achieved without altering caloric intake or body weight, highlighting that nutrient-rich fruits like avocado and mango can bolster cardiovascular health with minimal lifestyle adjustments.
“This research reinforces the efficacy of food-first strategies in mitigating cardiovascular disease risk, particularly for vulnerable groups like those with prediabetes,” stated Professor Barton-Freeman.
“This reassuring message suggests that integrating small, nutrient-dense foods, such as avocado or mango into meals and snacks, can enhance heart health without imposing rigid dietary restrictions.”
The AM group also saw increased intake of fiber, vitamin C, and heart-friendly monounsaturated fats—nutrients linked to cardiovascular wellness—while maintaining steady caloric consumption and body weight.
Additionally, markers of kidney function, such as estimated glomerular filtration rate (eGFR), showed improvement.
While no significant differences were observed in cholesterol, blood sugar, or inflammation levels, the findings underscore the importance of adding nutrient-rich fruits to the diet, especially for those at risk of type 2 diabetes and cardiovascular disease.
“In summary, enhancing fruit intake—particularly through increased avocado and mango consumption—led to beneficial alterations in vascular function crucial for cardiovascular health in high-risk populations,” the authors concluded.

Discover the fascinating skeleton of the Alvarezauroid dinosaur species Arunachetri seropolisiensis. This groundbreaking find includes two specimens from Patagonia, Argentina, along with two from the Northern Hemisphere, providing insights into how this enigmatic lineage of theropod dinosaurs evolved and dispersed before the separation of continents, challenging established beliefs regarding its origins.

Learn more about Arunachetri seropolisiensis, which thrived in Argentina during the Cenomanian period of the Late Cretaceous, approximately 90 million years ago.
This species was initially described from partial remains in 2012 and is categorized under Alvarez Sauroidea.
These unique small dinosaurs are noted for their tiny teeth and short arms, each ending in a prominent thumb claw.
“The Alvarezauroidea represents a mysterious clade of mainly small theropod dinosaurs, primarily found in the Jurassic to Cretaceous periods of Asia and South America,” states paleontologist Peter Makowiecki from the University of Minnesota, Twin Cities, along with his research team.
“Late Cretaceous Alvarezauroids are believed to have been carnivorous, primarily consuming ants, and possessing specialized forelimbs suitable for digging, microscopic supernumerary teeth, and heightened sensory abilities.”
“They are thought to have undergone evolutionary miniaturization alongside dietary specialization.”
The almost complete skeleton of Arunachetri seropolisiensis was discovered in the La Buitrera fossil site in Rio Negro, northern Patagonia.
Microscopic examination confirmed that this specimen was an adult, estimated to be at least four years old.
Weighing less than 0.9 kg (2 lb), it ranks as one of the smallest-known dinosaurs from South America.
In contrast to its later relatives, Arunachetri seropolisiensis featured longer arms and larger teeth.
Paleontologists conclude this indicates that some alvaresaurids transitioned into smaller forms well before they developed adaptations for an ant-based diet.
Researchers, by analyzing previously discovered alvaresaurid fossils housed in museums across North America and Europe, further demonstrate that these dinosaurs originated earlier than previously presumed, existing during the period when the continents were still part of the supercontinent Pangaea.
Their distribution appears to have resulted from the fragmentation of Earth’s landmass, making ocean crossings unlikely.
“Our biogeographical study suggests a Pangean ancestral distribution for Alvarezsauroroidea, indicating that the clade’s early history was primarily influenced by surrogates,” the scientists remarked.

Astrophysicists from the University of Illinois and the University of Chicago have pioneered a groundbreaking method to determine the Hubble constant, which quantifies the rate of the universe’s expansion. By utilizing the subtle background sound of gravitational waves, this innovative technique is poised to transform our understanding of cosmic evolution and may resolve key debates in contemporary astrophysics.

“This discovery holds significant importance. To address the ongoing Hubble tension, obtaining an independent measurement of the Hubble constant is crucial,” stated Professor Nicolas Younes from the University of Illinois.
“Our approach innovatively leverages gravitational waves to enhance the accuracy of Hubble constant measurements.”
Professor Younes and colleagues introduced a novel gravitational wave method utilizing the faint “background hum” from numerous distant black hole mergers to enhance Hubble constant estimations.
In contrast to traditional measurement techniques, this method capitalizes on space-time distortions, or gravitational waves, which carry valuable insights about vast cosmic distances and the velocity of receding celestial bodies.
Astrophysicists have termed this approach the “stochastic siren” method.
“By observing distinct black hole mergers, we can ascertain the frequency of these events throughout the universe,” remarked Bryce Cousins, a graduate student at the University of Illinois.
“Considering their velocity, we anticipate many additional events occurring that remain undetected, referred to as the gravitational wave background.”
“Discovering a completely new tool for cosmological research is a rare occurrence,” added Daniel Holtz, a professor at the University of Chicago.
“We demonstrated that we can unravel the age and composition of the universe by harnessing the ambient sound of gravitational waves resulting from the merger of black holes across distant galaxies.”
“This is an exhilarating and entirely novel direction, and we eagerly anticipate applying our method to future datasets to assist in determining the Hubble constant and other vital cosmological parameters.”
As the sensitivity of gravitational wave detectors improves, the stochastic siren method could lay the foundation for precision cosmology.
Detection of gravitational wave backgrounds is anticipated within the next six years.
Until then, the method gradually restricts higher Hubble constant values as improved upper background limits emerge, providing additional insights into the Hubble tension even without full detection capabilities.
“This initiative should pave the way for future applications, enhancing our sensitivity and ability to better filter and potentially detect the gravitational wave background,” Cousins noted.
“We hope that incorporating this information will yield superior cosmological insights and bring us closer to resolving the Hubble tension.”

“It’s an extreme environment, hidden from our view, now revealed in stunning detail,” remarked ESO astronomer Dr. Ashley Burns.
In collaboration with the ALMA CMZ Exploration Survey (ACES), Dr. Barnes and colleagues have meticulously mapped over 650 light-years of the Central Molecular Belt, enveloping our galaxy’s supermassive black hole.
This groundbreaking study offers the most detailed view to date of the cold gas fueling star formation in this turbulent region, detecting a variety of molecules from simple silicon compounds to complex organic species.
“This is the closest galactic nucleus to Earth that we can study with such granularity,” Dr. Burns stated.
“While designing the survey, we anticipated a high level of detail, yet we were genuinely astonished by the intricate complexity unveiled in the final mosaic,” said Dr. Katharina Immer, ALMA astronomer at ESO.
This unique dataset introduces never-before-seen central molecular zones, illustrating gas structures spanning tens of light-years down to minute gas clouds surrounding individual stars.
“The central molecular belt harbors some of the most massive stars known in our galaxy. Many of these stars have short lifespans, culminating in spectacular supernova events,” explained ACES leader Professor Steve Longmore, astrophysicist at Liverpool John Moores University.
With the ACES project, astronomers aim to deepen our understanding of how such phenomena influence star formation and whether existing theories of star formation apply even in extreme environments.
“By investigating star formation in the central molecular belt, we can elucidate how galaxies develop and change over time,” Professor Longmore added.
“We believe this region shares many traits with galaxies in the early universe, where star formation occurs in chaotic, extreme settings.”
Approximately 40,000 years ago, early humans in Europe created a sophisticated system of geometric symbols. These symbols are believed to represent an intentional, repeatable form of communication that transcends mere decoration. Discover more in a recent study published in Proceedings of the National Academy of Sciences.
Movable artefact featuring geometric symbols from the Swabian Aurignacian culture. Image credit: Christian Bentz & Ewa Dutkiewicz, doi: 10.1073/pnas.2520385123.
According to researchers Christian Benz from the Universities of Saarland and Passau, and Eva Dutkiewicz from the National Museum in Berlin, “Around 45,000 years ago, modern humans migrated into eastern and central Europe.”
During this migration, they encountered Neanderthals, their distant relatives.
In a period of rapid population turnover, modern humans produced a variety of movable artifacts, including tools and figurines crafted from materials such as ivory, bone, and antler.
These artifacts date back to the early Upper Paleolithic and are part of the Aurignacian technocomplex.
Numerous objects adorned with geometric symbols have been discovered, particularly in France’s Dordogne region, Germany’s Swabian Jura, and Belgian archaeological sites.
The researchers examined a collection of 260 mobile Aurignacian artifacts found in caves in the Swabian Jura.
These remarkable items, made from mammoth ivory, bone, and horn, date between 43,000 and 34,000 years ago.
Artifacts include tools, beads, musical instruments, and figurines representing both animals and humans, many etched with sequences of geometric signs—dots, lines, crosses, and more.
The scientists emphasized, “The inhabitants of these caves produced specialized tools for cutting meat, processing animal hides, and crafting clothing and ropes during this period.”
They also pioneered the flute, the first musical instrument made from bone and ivory.
Utilizing information theory and quantitative linguistics, the authors analyzed over 3,000 geometric symbols from the artifacts.
They assessed characteristics like repetition, diversity, and overall information density within the engraved symbols.
Dr. Benz noted, “While many theories exist, there has been minimal empirical research on the measurable properties of these symbols.”
The results revealed intriguing findings. Statistically, these Paleolithic symbols differ significantly from modern writing, which usually favors less repetition and denser information.
However, they bear a resemblance to Protocuneiform, the earliest known accounting symbols from Mesopotamia, used about 5,500 years ago.
This similarity doesn’t indicate that Ice Age Europeans had a writing system, as true writing encodes spoken language, while the Aurignacian symbols do not.
Instead, these artifacts illustrate a stable, traditional system for visually storing and conveying information without language.
The placement of symbols matters; figurines, particularly ivory ones, display a greater complexity and denser arrangement than everyday tools.
Specific symbols were exclusive to certain subjects, with dots frequently appearing on human and feline figures, while crosses were found on mammoths and horses, but never on human forms.
This pattern indicates a shared set of rules passed down through generations.
Researchers noted that unlike precuneiform, which evolved into a comprehensive script as ancient societies grew more complex, the structure of the Aurignacian symbol system remained remarkably consistent over roughly 10,000 years.
Dr. Benz stated, “Our analysis reveals that these symbol sequences have no correlation to contemporary writing systems, which represent spoken language and feature high information density.”
In contrast, the symbols found in archaeological artifacts often showcase repetitive patterns: cross, cross, cross, line, line, line, a hallmark absent in spoken language.
“Our findings also indicate that Paleolithic hunter-gatherers developed symbols with an information density statistically akin to the earliest proto-cuneiform tablets from ancient Mesopotamia, which emerged 40,000 years later.”
Proto-cuneiform symbols exhibit a similar repetitive quality, with individual symbols appearing at consistent rates, showcasing comparable complexity.
This discovery supports the growing consensus among archaeologists that symbolic communication likely evolved gradually through systems aimed at recording numbers, events, or social knowledge, rather than emerging suddenly as writing.
Some symbols may have tracked seasonal patterns, hunting data, or ritual concepts, though their precise meanings remain elusive.
Dr. Dutkiewicz added, “Modern humans have the benefit of thousands of years of accumulated knowledge that was unavailable to our ancestors. However, anatomically, Stone Age humans may have possessed cognitive abilities akin to ours.”
“The capacity to record and share information was crucial for Paleolithic humans, possibly enhancing their ability to coordinate groups and improve survival strategies.”
“They were adept craftsmen, evident in the portability of many of these artifacts, which often fit seamlessly in the palm of the hand, reminiscent of proto-cuneiform tablets.”

Astronauts Finke, Cardman, Yui, and Platonov have been stationed on the International Space Station (ISS) since early August, with plans originally extending until late February.
However, following an incident, NASA executives and the agency’s medical director decided to bring the astronauts back to Earth one week early.
Finke stated, “After a thorough evaluation, NASA has concluded that the safest decision is to return Crew-11 early. It is not an emergency; rather, it is a crafted plan to utilize advanced medical imaging technology not accessible on the space station.”
The Crew-11 astronauts departed the ISS on January 14, undocking from the space station in the same SpaceX Dragon capsule that initially transported them. Following an 11-hour journey, the capsule landed in the Pacific Ocean off the San Diego coast during the early morning hours on January 15.
NASA Administrator Jared Isaacman remarked in a post-landing news conference that while there were “serious conditions” in orbit, the crew has remained safe and stable since the incident.
Finke expressed gratitude towards his Crew-11 teammates, including NASA astronaut Chris Williams and Russian cosmonauts Sergei Kud Sverchkov and Sergei Mikayev. He also acknowledged the instrumental support from the teams at NASA, SpaceX, and medical professionals at Scripps Memorial Hospital La Jolla.
“Their professionalism and commitment undoubtedly led to positive outcomes,” he added.
Finke concluded by sharing that he is “doing very well” and is engaging in standard post-flight repair work at NASA’s Johnson Space Center in Houston.
“Spaceflight is an incredible privilege that humbles our humanity,” he said. “Thank you for your continued support.”

SpaceX’s Ambitious Satellite Launch Plans

As approval deadlines loom, astronomers are working diligently to assess the environmental implications of SpaceX’s request to launch up to 1 million satellites.
On January 30, SpaceX revealed its application to the US Federal Communications Commission (FCC) to deploy a vast constellation aimed at serving as an orbital data center for artificial intelligence, as stated by CEO Elon Musk.
This proposed number of satellites far exceeds the current total in orbit, which stands at only 14,500 active satellites. At present, the FCC is not mandated to evaluate the potential environmental consequences of launching such a significant number of satellites, especially regarding their impact on Earth’s atmosphere and nighttime visibility.
“We have serious concerns,” remarked Ruskin Hartley, CEO of DarkSky International. “We support satellite use, but it must be conducted responsibly.”
Following satellite applications, the FCC allows public comments. This process occurred shortly after SpaceX’s proposal, which is swift compared to typical timelines. The deadline for submissions is March 6, after which the FCC might take several months to decide on the application.
More than 350 comments have been submitted thus far, with many astronomers voicing their apprehensions about the implications for astronomy and Earth’s atmosphere. “The idea of a million satellites is incredibly alarming,” noted Samantha Lawler from the University of Regina, Canada.
SpaceX has not disclosed extensive details about the proposed satellites, specifically regarding their sizes and altitudes. This lack of information prevents astronomers from fully understanding the potential impacts of the constellations. “We are hurrying to gather crucial data to submit to the FCC,” Lawler added.
In a worst-case scenario, Lawler suggests that tens of thousands of satellites could be visible to the naked eye simultaneously, greatly obstructing observations from telescopes both on Earth and in space. Furthermore, it would necessitate continual satellite replenishment, likely every five years, similar to SpaceX’s Starlink system. Consequently, an average of one satellite would launch and another would re-enter Earth’s atmosphere every three minutes—significantly more than the current rate of a few re-entries daily.
This frequent re-entry poses serious risks to Earth’s atmosphere, as burning satellites produce aluminum oxide, a substance harmful to the ozone layer. “We’re discussing Teragrams [1 trillion grams]. This could lead to substantial ozone depletion and alter stratospheric temperatures,” Lawler warned.
The FCC currently lacks the obligation to evaluate the environmental impacts of satellite usage at such a comprehensive scale, due to exemptions under the U.S. National Environmental Policy Act. Should significant concerns arise during the public comment period, the application may face closer scrutiny; however, the likelihood of this remains uncertain, according to Kevin Bell from the Free Information Group in Washington, D.C.
“Ideally, the FCC would conduct assessments, but they often lack the scientific capacity to fully evaluate atmospheric impacts,” Bell explained.
Neither the FCC nor SpaceX has responded to requests for comment.

The nearly complete skeleton of a small dinosaur, weighing less than a domestic chicken, has provided significant insights into the evolution of Alvarezaurus, one of the smallest dinosaur species ever documented.
This 95 million-year-old fossil, identified as Arunashetri seropolisiensis, was unearthed in 2014 at the La Buitrera site in northern Patagonia, Argentina.
The first specimen of Arunashetri consisted of incomplete hind limb bones found in 2012. Peter Makowiecki from the University of Minnesota contributed to the research on this new fossil. At the time, only fragmentary remains were available, leaving the classification as a probable alvaresaurid. “We didn’t even know if it was a juvenile or an adult,” says Makowiecki.
“With the entire skeleton now complete, we suddenly have all the information required to understand how Arunashetri functioned. Its anatomical structure is both similar and distinct from other species, providing key insights into the evolution of Alvarezsaurus’s unusual anatomy,” notes Makowiecki.
The new fossil features very elongated and slender hind limbs, along with unexpectedly long forelimbs equipped with three well-developed fingers. Detailed analysis revealed that this dinosaur was an adult, estimated to be at least four years old.
It is believed that it weighed only 700 grams in its lifetime. “These specimens are incredibly small, even smaller than a chicken,” explains Makowiecki.
Previously, Alvarezsaurus was thought to be an early ancestor of birds. Recent findings clarify that while Arunashetri may have superficially resembled a bird, it, along with all Alvarezsaurus, are indeed non-avian theropods. “This new discovery confirms our understanding,” states Makowiecki.
It was once believed that all small alvaresaurids had short, robust forelimbs with prominent thumbs but reduced lateral digits and small teeth, interpreted as evolutionary adaptations for a diet of ants and termites. However, as Makowiecki points out, “Arunashetri does not fit that mold. Although it is a smaller member of the Alvarezauridae family, it signifies a relatively early branch in the evolutionary tree, hence its teeth and forelimbs remain quite substantial.”
In fact, he adds, its forelimbs are more characteristic of other theropods rather than anteater specialists. “Arunashetri, while smaller, structurally resembles a typical theropod. Considering its size, it likely consumed a significant variety of invertebrates, along with a broader prey spectrum,” he further explains.
This indicates that paleontologists still lack a full understanding of why these dinosaurs evolved to such small sizes. “We are left with a vague understanding that Alvarezsaurids successfully occupied a very small predator niche,” concludes Makowiecki.
Infrared saunas are a leading wellness trend, gaining popularity in gyms, spas, and personal homes. Advocates highlight numerous benefits, including enhanced heart health and effective pain relief.
Unlike traditional Finnish saunas that heat the air, infrared saunas use light from infrared bulbs to directly warm your body. This results in a milder temperature of around 60°C (140°F), compared to the 75°C (167°F) typical of traditional saunas.
Infrared saunas are generally compact. If you prefer a less intense heat experience or wish to avoid the crowded atmosphere of Finnish saunas, an infrared sauna might be your ideal option.
You will still experience sweating, as this mirrors the positive effects of exercise. According to various heat therapy studies, infrared saunas can escalate heart rates, lower blood pressure, alleviate muscle tension, and enhance blood circulation. They may also promote the release of endorphins, improving mood while reducing stress.
Research on infrared saunas indicates benefits for cardiovascular health, resembling light exercise effects, and pain reduction, particularly for chronic pain sufferers. Some animal studies suggest that infrared therapy might help decrease inflammation and motivate mitochondrial activity within our cells.

However, it’s worth noting that comprehensive studies on infrared saunas are few, often limited by participant numbers. Conducting large-scale studies poses logistical challenges and costs.
Despite the lack of extensive evidence, the infrared sauna trend is on the rise. You can install one at home for approximately £3,000 (around $3,900 USD). Additionally, infrared Pilates and yoga classes are emerging, offering a chance to experience the benefits before making a purchase.
This article addresses the query from Ross McDowell of Birmingham: “Should I start using an infrared sauna? Is it safe?”

Recent advancements in quantum computing have decreased the power required to breach standard encryption techniques by tenfold. With this remarkable reduction, common encryption methods face heightened vulnerability, prompting concerns about future security.
The RSA algorithm, a staple in online banking and secure communications, relies on the intricate task of factoring two large prime numbers. While the possibility of using quantum computers to bypass this challenge was theorized since the 1990s, the physical size requirements of such quantum systems previously rendered them impractical.
However, this landscape is shifting. In a groundbreaking 2019 study, Craig Gidney, from Google’s Quantum AI, outlined a method that significantly lowered this requirement from 170 million qubits to just 20 million. Furthermore, by 2025, Gidney plans to bring it down to below one million qubits. Most recently, Paul Webster and his Australian team at Iceberg Quantum cut this estimate to approximately 100,000 qubits.
Their research expands on Gidney’s algorithm improvements while incorporating a new methodology called qLDPC coding, which enhances qubit connectivity beyond immediate neighbors. This modification increases the overall information density possible in quantum systems.
Based on their findings, the team predicts that cracking a prevalent RSA encryption could become feasible within about a month using 98,000 superconducting qubits—those presently manufactured by tech giants like IBM and Google. To achieve this in just one day, a staggering 471,000 qubits would be necessary.
Some quantum computing firms aspire to develop machines with hundreds of thousands of qubits within the next decade. However, these optimistic calculations overlook material considerations and focus primarily on error rates and computational speed. What happens if the Iceberg Quantum approach is feasible? An entity controlling such a quantum computer could potentially access private emails, bank accounts, and governmental data secured via RSA encryption.
“The stringent requirements pose a significant challenge in hardware manufacturing—the toughest hurdle,” Gidney comments. Similarly, Scott Aaronson from the University of Texas at Austin expressed concerns about the practicalities of configuring connections between distant qubits on his blog here.
IBM has been an advocate for qLDPC coding recently, making strides in making its quantum hardware compatible. However, the extent of success with this methodology remains uncertain. An IBM spokesperson noted that qLDPC codes form the “foundation” of their quantum computing technology but did not elaborate on the feasibility of Iceberg’s innovations.
Facilitating connections between distant qubits is simpler when using extremely cold atoms or ions—two emerging strategies in the quantum computing arena. Yet these systems are often slower, and recent research indicates that unlocking RSA encryption may still require millions of qubits.
“It’s crucial to maintain a flexible perspective on the timeline for such breakthroughs,” states Lawrence Cohen from Iceberg Quantum. “Should RSA be compromised, the fallout could be immense. It’s better to be proactive than reactive.”
Although breaking RSA encryption is a well-researched issue, it serves as an excellent benchmark for those pursuing powerful quantum systems. Moreover, the team’s techniques might also enhance simulations of quantum materials and quantum chemistry.
NASA is set to return the massive Space Launch System (SLS) rocket to its hangar for crucial repairs on Wednesday, postponing the launch of four astronauts on the highly anticipated Artemis II mission around the moon by at least a month.
The towering 322-foot SLS rocket has been stationed on the launch pad at Florida’s Kennedy Space Center since mid-January. However, engineers recently identified a blockage affecting the helium flow to part of the rocket’s upper stage, necessitating further investigation.
This rollback means that NASA will miss its planned launch window for the Artemis II mission in March. While officials indicate that a trial launch could potentially happen in April, the exact schedule hinges on the outcomes of the ongoing repairs.
“We recognize that this news is disappointing,” NASA Administrator Jared Isaacman expressed on Saturday. In a post on X, he added, “That disappointment is strongest among the dedicated NASA team that has tirelessly prepared for this monumental mission.”
Retrieving the rocket back to the hangar is a substantial task. The four-mile trek is scheduled to begin Wednesday morning around 9 a.m. ET, though this process is characteristically slow and may take up to 12 hours. Weighing 11 million pounds, the rocket transports the Orion capsule and is moved by a mobile platform known as a crawler transporter, advancing at a leisurely pace of about 1 mile per hour.
Once the rocket reaches the hangar, officially known as the Vehicle Assembly Building, the team will establish a platform to facilitate engineers’ access to the site where the helium flow issue was identified.
During the rocket’s stay in the Vehicle Assembly Building, NASA plans to replace and test the batteries for the upper stage and the safety mechanism known as the flight termination system.
AI Chooses Nuclear Weapons with Alarming Frequency
Credit: Galerie Bilderwelt/Getty Images
Recent studies reveal that advanced AI models exhibit a concerning willingness to deploy nuclear weapons, mirroring the hesitance exhibited by humans during geopolitical crises.
Kenneth Payne from King’s College London organized a wargame featuring three prominent language models: GPT-5.2, Claude Sonnet 4, and Gemini 3 Flash. Scenarios encompassed critical international conflicts, including territorial disputes, resource competition, and threats to regime stability.
The AI models operated on an escalation ladder, enabling them to select responses ranging from diplomatic protests to full-scale nuclear warfare. Over the course of 21 wargames, they executed 329 turns and produced around 780,000 words explaining their decision-making processes.
In a striking 95% of these simulated engagements, at least one tactical nuclear weapon was deployed by the AI. “Nuclear taboos do not seem as entrenched for machines as they are for humanity,” Payne noted.
Additionally, none of the models opted for full surrender, regardless of their losing positions. Instead, they generally sought to reduce violence temporarily. In 86% of conflicts, unintended escalations occurred beyond initial AI intentions due to miscalculations in the fog of war.
“From a nuclear risk standpoint, these results are alarming,” cautioned James Johnson from the University of Aberdeen. He expressed concerns that AI could amplify one another’s responses, leading to catastrophic outcomes.
This issue is particularly crucial as AI systems are already being integrated into military wargames worldwide. “While significant powers utilize AI in simulations, the extent of its integration into actual military decision-making remains uncertain,” remarked Tong Zhao from Princeton University.
Zhao believes that countries may understandably hesitate to delegate nuclear decision-making to AI. Payne echoes this sentiment, stating, “It is unlikely any nation would entrust a machine with nuclear control.” However, in situations with urgent time constraints, military strategists might be compelled to lean on AI systems.
He questions whether AI’s perceived lack of human fear may be the sole reason for its propensity toward aggression, positing that a fundamental disconnect in understanding the ‘stakes’ of nuclear engagement may exacerbate risks.
The implications for mutually assured destruction—the notion that no leader would initiate a nuclear strike due to retaliation—remain unclear, according to Johnson.
When one AI model deployed a tactical nuke, the opposing AI de-escalated only 18% of the time. “AI could enhance deterrence by making threats more credible,” Johnson added. “AI won’t dictate nuclear war, but it could significantly influence the perceptions and timelines that inform human decision-making.”
As of now, leading companies like OpenAI, Anthropic, and Google, which developed the AI models involved in this research, have not commented on these findings. New Scientist has sought their insights.
The lifespan benefits derived from fasting and rapamycin usage resemble a lottery rather than a guaranteed outcome. While significant lifespan increases have been observed within a year, reanalysis indicates that results can vary significantly among individuals.
Talia Fulton, a researcher at the University of Sydney, mentions, “[They] may enhance your lifespan marginally [they] could dramatically increase it.”
The 2025 study examined 167 research papers across eight non-human species, including fish, mice, rats, and rhesus macaques. Fulton and her team discovered that when these animals were treated with rapamycin, a promising anti-aging compound, alongside calorie restriction — known for fostering longevity — they exhibited a longer lifespan on average. This suggests the same potential could extend to humans.
Current research has investigated the varied responses to longevity interventions in individual animals, revealing significant variability in benefits. Fulton notes that while taking rapamycin or implementing dietary restrictions appears “likely to be advantageous, the degree remains uncertain.”
According to her, “Some may experience considerable lifespan extension, while others may see minimal impact, or not outlive their expected lifespan.” This variability creates a somewhat unpredictable environment, meaning these treatments cannot guarantee lifespan extension for all individuals.
Fulton emphasizes that the objective of longevity interventions is to balance the population size with life expectancy through a squared curve. This implies that more individuals could lead longer lives, contrasting with the current trend of fewer individuals achieving longevity. “Squaring the survival curve means a larger number will lead extended and fulfilling lives until around 100, at which point mortality becomes almost certain,” she elaborates.
Current findings indicate that dietary restrictions and rapamycin do not effectively square this longevity curve. In this context, Fulton advises holding off on high expectations until further research clarifies who stands to benefit most from these approaches. “We aspire to decode individual genetic variables and life histories, ultimately determining ‘This is precisely what you need to achieve maximum longevity,'” she states.
Researchers like Matt Kaeberlein from the University of Washington stress that squaring the curve does not inherently mean enhanced health profiles. A more compelling consideration, he argues, is whether longevity initiatives, such as exercise, influence “healthspan inequality.”
Originally developed as an immunosuppressant for organ transplant patients, rapamycin inhibits the mTOR protein, essential for cell growth and division. At lower doses, it has demonstrated the potential to extend lifespan in species like flies and mice, potentially by safeguarding against DNA damage.
Recent findings from museum collections in Australia and the United States showcase the incredible diversity of the Western Australian trematosaurid temnospondyl, underscoring how early marine amphibians proliferated across the continent shortly after the end-Permian mass extinction.

“The catastrophic end-Permian mass extinction and severe global warming gave rise to modern marine ecosystems at the dawn of the Mesozoic Era, around 252 million years ago,” stated Dr. Benjamin Kjaer from the Swedish Museum of Natural History and his colleagues.
“This significant evolutionary milestone marked the early emergence of sea-going tetrapods (limbed vertebrates), including amphibians and reptiles that quickly established themselves as dominant aquatic apex predators.”
“To date, the earliest sea monster fossils have primarily been documented in the Northern Hemisphere.”
“In contrast, the fossil record from the Southern Hemisphere remains geographically sparse and inadequately understood.”
Paleontologists recently analyzed marine amphibian fossils from the renowned Kimberley region of Western Australia’s far north.
“These fossils were uncovered during scientific expeditions in the early 1960s and 1970s,” the researchers noted.
“The specimens were subsequently distributed to various museum collections across Australia and the United States.”
“The results of this research were initially published in 1972, identifying a single species of marine amphibian, Erythrobatrachus nooncambahensis, named after skull fragments discovered at Noonkumba Farm, east of Derby in the Kimberley region.”
“Unfortunately, the original fossil of Erythrobatrachus has since been lost over the past 50 years.”
“This prompted a survey of international museum collections, leading to the rediscovery and reanalysis of these ancient marine amphibian remains in 2024.”
According to scientists, Erythrobatrachus is classified within the trematosaurid family of temnospondyls.
“Trematosaurids bore a superficial resemblance to crocodiles and were related to modern salamanders and frogs, reaching lengths of up to 2 meters (6.6 feet),” the researchers explained.
“These fossils hold significant importance as they were found in rocks deposited as coastal sediments less than a million years after the end-Permian mass extinction.”
“Thus, they represent the oldest currently recognized groups of Mesozoic marine tetrapods in geological terms.”
However, detailed investigations revealed that the skull fragments of Erythrobatrachus were not unified but belonged to at least two distinct types of trematosaurids: Erythrobatrachus and another species from the well-known genus Aphanelamma.
“Examination of Erythrobatrachus using advanced 3D imaging indicated the skull measured approximately 40 centimeters (16 inches) when intact, suggesting it was a robust, broad-headed apex predator,” the authors stated.
“Conversely, Aphanelamma were similar in size but featured elongated snouts adapted for catching smaller fish.”
“Both types of trematosaurids occupied the water column yet targeted different prey within the same habitat.”
“Furthermore, the fossils of Erythrobatrachus are uniquely found in Australia, while Aphanelamma has been discovered in similarly aged deposits across regions like the Scandinavian Arctic, Svalbard, the Far East, Pakistan, and Madagascar.”
“The Australian trematosaurid fossils provide evidence that these early Mesozoic marine tetrapods not only radiated swiftly into various ecological niches but also dispersed globally along the coastal margins of interconnected supercontinents during the initial two million years of the dinosaur epoch.”
The team’s study was recently published in the Journal of Vertebrate Paleontology.

The NGC 5134 galaxy is located around 65 million light-years from Earth, making it a significant celestial object in the Virgo constellation.
Also referred to as ESO 576-52, LEDA 46938, and IRAS 13225-2052, NGC 5134 was first discovered by the renowned German-British astronomer William Herschel on March 10, 1785.
This galaxy is a member of the NGC 5084 group, which consists of five galaxies, including NGC 5084, NGC 5087, ESO 576-50, and ESO 576-40.
According to Webb astronomers, “The relative proximity of these galaxies enables Webb to uncover remarkable details about NGC 5134’s tightly coiled spiral arms.”
The latest infrared images of NGC 5134 are derived from observations taken by Webb’s Mid-Infrared Instrument (MIRI) and Near-Infrared Camera (NIRCam).
“MIRI collects mid-infrared radiation emitted by warm dust in NGC 5134’s interstellar cloud, allowing astronomers to track dusty gas clumps,” the researchers noted.
“Some of this dust comprises complex organic molecules known as polycyclic aromatic hydrocarbons, characterized by interconnected carbon atoms, providing insight into the chemistry within interstellar clouds.”
“NIRCam specializes in capturing near-infrared light at short wavelengths from the stars and star clusters dotting the spiral arms of NGC 5134.”
“The combination of MIRI and NIRCam data illustrates a galaxy in a continuous state of change and evolution.”
According to the researchers, “The gas clouds flowing along NGC 5134’s spiral arms are prolific sites for star formation; each new star formed consumes some of the star-forming gas that sustains the galaxy.”
“When a star reaches the end of its life, part of its gas is recycled back into the galaxy, contributing to the cycle of star formation.”
Massive stars, those exceeding eight times the mass of the Sun, endure dramatic cataclysmic supernova explosions that disperse stellar material over vast distances.
Other stars, like our Sun, gently return some of their material; they expand into red giants before shedding their atmospheres and releasing gas into space.
WWhether expelled by a supernova or a gentle red giant, this gas may eventually be integrated into new star formation processes.
A large prospective cohort study has revealed that older adults consuming more virgin olive oil, a vital element of the Mediterranean diet, experience slower cognitive decline and enhanced gut microbiota diversity over two years. Conversely, higher consumption of common refined olive oil correlates with decreased microbial diversity and accelerated cognitive decline.

Virgin olive oil is a key ingredient of the Mediterranean diet, packed with phenolic compounds known for their anti-inflammatory and antioxidant benefits.
While prior laboratory and animal research hinted at neuroprotective effects, human studies linking olive oil, gut microbiota, and cognitive function remain sparse.
This groundbreaking finding stems from participants in the PREvención con DIeta MEDiterránea-Plus (PREDIMED-Plus) study, an extensive ongoing trial designed to explore how dietary and lifestyle changes influence cardiovascular and metabolic health.
“This is the first prospective human study analyzing the role of olive oil in the relationship between gut microbiota and cognitive function,” stated Dr. Giaki Ni, a researcher from Rovira i Virgili University.
Researchers monitored over 650 adults aged 55 to 75, who were overweight or obese and at high risk for cognitive decline, yet cognitively healthy at the study’s onset.
During a two-year period, they assessed participants’ olive oil intake, gut microbiome profiles, and performance on a comprehensive range of cognitive tests.
Increased consumption of virgin olive oil was linked to improved or sustained overall cognition, executive function, and language proficiency.
In stark contrast, high consumption of common refined olive oil appeared to diminish gut microbial diversity and accelerate cognitive decline.
“As cases of cognitive decline and dementia rise, our findings underscore the necessity of enhancing diet quality. Prioritizing extra virgin olive oil over refined options emerges as a simple yet effective strategy to safeguard brain health,” emphasized researchers Nancy Babio and Stéphanie Nisi from Rovira i Virgili University.
To uncover why virgin olive oil may positively impact cognitive function, scientists analyzed baseline stool samples.
Those who consumed higher amounts of virgin olive oil exhibited greater gut microbiota diversity and a more cohesive microbial community structure compared to those who consumed less.
Further analysis indicated that specific gut bacteria may elucidate the cognitive advantages. Changes in the prevalence of particular microbial species, such as adlerkreuzia, appeared to mediate the relationship between virgin olive oil intake and enhanced cognitive performance, reinforcing the concept that diet influences brain health via the gut-brain axis.
“This study highlights that the quality of fats we consume matters as much as their quantity,” remarked Dr. Jordi Salas Salvado, also from Rovira y Virgili University.
“Extra virgin olive oil not only benefits heart health but also plays a vital role in protecting brain function as we age.”
“The discovery that microbial profiles contribute to these benefits opens avenues for new nutrition-based prevention strategies to maintain cognitive function.”

Killer Whales Face Cannibalism Risks
François Gouy/VWPics/Alamy
Recent observations by biologists indicate the occurrence of orca-on-orca predation in the North Pacific, suggesting that such cannibalistic behavior may be a reason why certain killer whales travel in extensive family groups.
There are two primary subspecies of killer whales (Orcinus orca) in the North Pacific Ocean. Transient killer whales, commonly known as Biggs killer whales, are nomadic, forming dynamic hunting pods to pursue seals, dolphins, and other whales. In contrast, resident killer whales maintain large family-oriented groups and stay close to their maternal ties throughout their lives. These residents disperse to hunt fish individually but reunite for resting or traveling.
Though it is believed that the two subspecies rarely interact, Sergey Fomin from the Russian Institute of Pacific Geography has recorded instances of aggressive encounters. While walking along the eastern shores of Bering Island, he noted bite marks on the dorsal fins of beaked and minke whales, remnants of predation by hungry killer whales. However, during the summer of 2022, he discovered a bloodied orca fin on the beach—its origin would be revealed two years later.
Through genetic analysis, it was found that the fin belonged to a southern killer whale, leading Fomin and colleagues to hypothesize that it was likely consumed by a Biggs killer whale.
Most toothed whales, including killer whales, exhibit fluid social structures with their pods changing frequently. The mystery of why southern killer whales form large family units has sparked scientific intrigue. “I’ve been curious about their social structure for a while, as it’s quite unique among species,” notes Olga Filatova from the University of Southern Denmark.
Upon hearing about the findings of the two dorsal fins and the potential for cannibalism, Filatova was intrigued. It’s possible that resident killer whales band together in large numbers for protection. She, along with Fomin and Ivan Fedutin, has published a study discussing this hypothesis.
Killer whales, being apex predators, rarely experience harassment. However, they have been observed being chased off by smaller pods of pilot whales. They are also known to display aggression towards one another. In 2016, Jared Towers of Bay Cetology reported witnessing a pod of Biggs killer whales attacking and killing a newborn. Towers speculated that because the calf was not consumed, this aggression was likely aimed at inducing sexual receptivity in the mother.
While it’s uncertain if the whales at Bering Island were cannibalized, Towers believes that the unique social structure of the residents likely serves as a defensive mechanism. Experts cannot dismiss the possibility that the fins were damaged during sparring or that the whales were consumed post-mortem. However, because deceased orcas typically sink, this scenario is less plausible.
Researchers can only theorize the reasons behind cannibalism in killer whales, with Filatova suggesting it may arise from necessity. With fur seals and sea lions being common prey on Bering Island, a shortage of food may prompt whales to consider alternative sources. “When food is scarce and a young killer whale presents itself, what choice do they have?” she remarks.

In the realm of quantum mechanics, the principle of no duplication for quantum information is considered an unbreakable rule. However, a novel technique for backing up qubits—the fundamental units of quantum computers—may potentially challenge this foundational aspect of physics.
Initially identified in the 1980s, the no-cloning theorem asserts that a quantum state, which encapsulates all information about a quantum system, cannot be duplicated. Attempts to copy this information typically compromise the fragility of the quantum properties being assessed. This principle is crucial for advancements in quantum technologies, including cryptography, enabling secure communication protocols that effectively prevent information duplication and interception.
Researchers from the University of Waterloo in Canada have introduced an unexpected breakthrough: the ability to clone a quantum system, provided the information is encrypted and accompanied by a unique one-time decryption key.
Achim Kemp states, “This method allows for the creation of numerous copies to enhance redundancy, yet all copies must remain encrypted, and each decryption key may only be utilized once.” This compliance with the no-cloning theorem assures that only a singular, unambiguous, readable copy of a qubit exists at any point.
Through an exploration of how quantum Wi-Fi and radio stations could function, Kemp and his team stumbled upon this astonishing revelation. Traditional no-cloning principles would inhibit multiple receivers from accessing identical quantum information.
While delving into the impact of random fluctuations and noise on information copying, the team discerned that these disturbances might inadvertently undermine the no-cloning theorem, prompting the question, “Why does quantum noise seem to confuse the no-cloning theorem?”
Upon thorough investigation, they concluded that noise could inadvertently serve as an encryption mechanism, disrupting the original signal, yet remaining reversible. When utilized intentionally, this phenomenon can act as a tool for secure information dissemination.
After validating this concept theoretically, the team successfully implemented the protocol on an actual IBM Heron 156-qubit quantum computing processor.
This innovative approach exhibits a level of resilience against the errors and noise characteristic of contemporary quantum computers, enabling the production of hundreds of encrypted clones of a single qubit. “In fact, we maximized our capacity on the IBM processor. Despite housing only 156 qubits, we estimated we could produce over 1,000 clones before triggering error messages,” Kemp explains.
This advancement to the no-cloning theorem holds promise for the future of quantum cloud storage and computing services. “Similar to how Dropbox ensures a file’s safety by storing it across three distinct geographical servers, this method offers a viable solution for duplicating quantum data,” Kemp adds.
Alex Kissinger from the University of Oxford remarks, “It’s a fascinating quantum cryptographic protocol with ample potential in quantum communications, where redundancy in transmitted information can be invaluable.” However, he emphasizes that this technique should not be misconstrued as cloning. “It signifies a method of dissemination rather than replication,” Kissinger clarifies. “It’s about distributing information so that one recipient can later retrieve it.”
Kemp concurs, asserting, “This isn’t cloning; it’s encrypted cloning—merely a refinement of the no-duplication theorem.”
Vitiligo results in paler, less pigmented skin patches.

A groundbreaking cream targeting the underlying cause of vitiligo is set to be available through the UK’s National Health Service (NHS). In clinical trials, this cream significantly improved pigmentation in white skin patches associated with this condition. Despite previous controversies surrounding vitiligo treatment, it is important to note that vitiligo is neither painful nor dangerous.
“Typically, individuals with vitiligo exhibit no physical symptoms, but the condition can lead to significant psychological challenges,” stated David Rosmarin from Indiana University, who led two trials for the new ruxolitinib cream treatment.
The cream, already marketed in the United States under the name Opzelura, is indicated for treating non-segmental vitiligo, characterized by symmetrical white patches on both sides of the body. This condition is believed to result from the immune system mistakenly attacking melanocytes—the cells responsible for producing melanin, which gives skin its color.
According to Emma Rush from Vitiligo Support UK, this treatment represents the first rigorously tested medication that directly addresses the mechanisms causing vitiligo. “This is a significant milestone in vitiligo treatment,” she remarked.
Ruxolitinib functions by inhibiting the activity of enzymes that destroy melanocytes. While existing treatment options like steroid creams may restore some pigmentation, they have broader immune-suppressing effects.
A recent study published in 2022 revealed that ruxolitinib enhanced pigmentation and decreased the visibility of vitiligo patches compared to a placebo cream. The effects were noted irrespective of the individual’s skin color (vitiligo tends to be more conspicuous on darker skin tones), and these results were sustained for at least one year after treatment cessation for over a third of participants.
The National Institute for Health and Care Excellence (NICE) has previously reviewed the efficacy of ruxolitinib and concluded that it is not cost-effective for NHS provision. However, it is now recommended that this cream be available to individuals aged 12 and older with non-segmental vitiligo when other topical treatments have proven ineffective or unsuitable.
“Patients and clinicians may sometimes believe that vitiligo does not require treatment since it is not life-threatening or physically painful,” noted Victoria Eleftheriadou of the British Association of Dermatologists. However, vitiligo can lead to serious complications, including depression and anxiety.
Natalie Umbersley, a vitiligo ambassador for the charity Changing Faces, stated that support groups encourage individuals with visible differences to seek treatment without fear of judgment but expressed her reluctance to pursue ruxolitinib after years of using existing therapies. “I have learned to embrace my unique skin,” she said. “It’s all about celebrating our individuality.”
“While it’s wonderful to have individuals who love their appearance, this is not the reality for everyone,” commented Rush.
While an oral form of ruxolitinib has been used to treat certain cancers and rheumatoid arthritis, it is associated with serious side effects such as lymphoma, heart disease, and infections. However, these risks are not reported with the topical formulation. In two vitiligo trials, ruxolitinib was linked to only mild side effects, including acne and itching. “Systemic absorption is minimal,” Eleftheriadou noted.
Ruxolitinib is also considered to be safer than long-term use of steroid creams, which can cause skin thinning. Additionally, ultraviolet light therapy may be an option for individuals with severe vitiligo, although it is not widely accessible.
Have you ever wondered why fossilized marine life, including trilobites, crinoids, and brachiopods, can be found on the summit of Mount Everest? These astonishing discoveries provide significant insights into the history of our planet.
The presence of these fossils indicates the formation of the Himalayas approximately 50 million years ago, serving as vital evidence supporting the theory of plate tectonics.
Around 200 million years ago, when the supercontinent Pangea began to fragment, the Indian plate started its journey northward, ultimately colliding with the Asian continent.
This monumental geological event caused the Indian plate to collide with the Eurasian plate, elevating land that included remnants of the ancient Tethyan Sea floor.
The impact resulted in the creation of the Himalayan mountain range and the Tibetan Plateau, pushing marine fossils more than 8,000 meters (26,000 feet) above sea level.
This article answers the question posed by Sonia Carroll of Brighton: “Why are there marine fossils on the top of Mount Everest?”

Discover Saturn’s Largest Moon, Titan: A Stunning View from the Cassini-Huygens Spacecraft

The origin story of Saturn and its spectacular rings may have been influenced by its largest moon, Titan. Approximately 400 million years ago, a collision involving an early proto-Titan and a smaller celestial body may have set off a chain reaction, resulting in the creation of Saturn’s iconic rings while altering the planet’s wobble and the orbits of its moons.
Saturn’s system is rife with enigmas. The rings are surprisingly younger than anticipated, the planet’s wobble is not correlated with Neptune’s gravitational influence as simulations suggested, and Iapetus, one of its moons, possesses a strangely tilted orbit. Titan itself is noted for its unique features, including a sparse number of craters and an eccentric orbit.
The collision that formed the Titan we observe today could elucidate many of these mysteries. “This creates a grand unified theory that addresses all primary issues,” said Matiya Chukku, the leader of the research team. “We had various hypotheses about each problem, and this could be the way they interconnect in one narrative that we can test.”
The theory begins with the proposition of a hypothetical moon named Chrysalis, located on the outer edge of Saturn’s system. Proposed in 2022, it was suggested to explain how Saturn’s wobble separated it from Neptune. It was theorized that Chrysalis was drawn towards Saturn, leading to a breakup and the formation of rings, thereby destabilizing Saturn’s wobble and the orbit of Iapetus. However, further simulations indicated that the most probable scenario would be for Chrysalis to collide with Titan.
This presents a complication, Chukku explains: “If Chrysalis collided with Titan, it couldn’t transform into rings.” Therefore, he and his team analyzed the ramifications of a potential impact with Titan. Their findings indicated that such a collision around 400 million years ago could have erased Titan’s craters, transformed its originally circular orbit into an elliptical one, and produced a cascade of debris. The smaller moon Hyperion might be formed from this debris, explaining why it appears significantly younger than Saturn’s other moons.
Over time, Titan’s orbital changes could have destabilized the smaller inner moons, causing them to collide and grind into the tiny particles now making up Saturn’s rings. “It all starts with Titan, leading to subsequent calamities in the internal systems,” Chukku states.
“If the collision in Titan’s early history can unravel many mysteries within the Saturn system, it underscores Titan’s significance in our understanding of Saturn as a whole,” adds Sarah Helst from Johns Hopkins University. “I value the elegance of resolving multiple Saturnian issues simultaneously.”
We are nearing the opportunity to gather evidence to confirm or refute this theory. NASA’s Dragonfly mission, set to launch in 2028 and arrive at Titan by 2034, will conduct comprehensive surface analyses of Titan, potentially elucidating whether Titan has merged with Chrysalis. Should this hypothesis hold, the peculiarities of Saturn may finally be explained.

I’m currently booking my shingles vaccination appointment. Having had shingles in college, I still bear the scars and want to avoid a recurrence. However, I understand that the shingles vaccine offers benefits beyond just shingles prevention. This is increasingly relevant; many vaccines are showing advantages that extend far beyond shielding against specific viruses or bacteria, a fact that’s lesser-known but crucial.
Starting with shingles, a study involving over 1 million individuals highlighted that those who received the Zostavax shingles vaccine experienced a 26% lower risk of dying from heart disease or suffering a stroke, heart attack, or heart failure over an average span of six years post-vaccination. This is a significant risk reduction through a simple and affordable intervention.
Additionally, recipients of the new shingles vaccine, Shingrix, were found to be 17 times less likely to develop dementia in the following six years compared to those inoculated with Zostavax. The overall risk reduction with Shingrix may be even more substantial, given that some studies suggest Zostavax also contributes to a decrease in dementia risk. Other vaccines, including those against influenza and tuberculosis, show similar protective benefits, with research indicating they may help lower dementia risk as well.
In both the US and Australia, shingles vaccination is advised for adults over 50 or anyone with weakened immune systems. In the UK, access is limited to public healthcare providers unless you fall under certain categories, such as people aged 70 to 79. Considering my age, I’ve opted for private vaccination to avoid the wait.
Shingles is caused by the varicella-zoster virus; initially causing chickenpox, it then remains dormant in nerve cells and can reactivate to cause shingles. Vaccinating children against chickenpox may offer benefits in adulthood, yet concrete studies on this are scarce.
The influenza vaccine also boasts cardiovascular advantages. Data compiled from over 9,000 participants in six trials indicated that flu vaccine recipients had a 34% reduced risk of heart attack or stroke within a year, with an even greater effect observed among individuals with recent heart issues.
Furthermore, a new vaccine for respiratory syncytial virus (RSV) also seems to contribute to heart disease prevention—an extensive study involving around 130,000 people over 60 revealed that those who received certain RSV vaccines had lower hospitalization rates for heart and lung issues compared to their unvaccinated counterparts.
The mRNA COVID-19 vaccine has additionally been shown to enhance immune responses in conjunction with immunotherapy, consequently prolonging life expectancy for some individuals.
While we could continue listing various examples, the focus should shift to understanding why so many vaccines possess such widespread benefits. While the exact mechanisms aren’t entirely known, they’re not entirely surprising.
Viral infections can cause lasting physical damage to the body and the immune response can also lead to tissue damage. Severe immune reactions, like cytokine storms, often lead to fatalities in infections such as influenza and COVID-19. Growing research indicates that the immune response to infections, like the Epstein-Barr virus, may contribute to conditions like multiple sclerosis.
Various viruses adopt different strategies to evade our immune system and compromise our natural defenses. HIV exemplifies this extreme by obliterating the immune system entirely.
Illustration of Human Papillomavirus (HPV)

Some viruses, like varicella-zoster, cannot be eliminated post-infection, while others, such as human papillomavirus (HPV), can integrate their genome into our cells, leading to cancer.
Even viral infections commonly perceived as benign, such as influenza in youth, can have undetected long-term effects. Ongoing research into long-term coronavirus implications has highlighted the importance of vaccines in preventing lasting harm.
Some advocate the notion that “natural immunity” gained from infection is superior to vaccination. This perspective can be misleading, especially when considering diseases like measles, which exemplify the critical need for vaccination.
However, it’s essential to note that not all vaccines possess this training capability. Some might be ineffective, yet they continue to save lives.
Ultimately, the pressing question remains: is getting vaccinated more advantageous than not? Making an informed decision requires weighing the risks of infection against vaccination risks, while also considering the broader benefits of immunization. Too often, the conversation centers on exceedingly rare or unfounded side effects of vaccines.
I firmly believe in the positive outcomes of vaccination. I consistently receive the shingles vaccine and flu vaccination annually, and I eagerly anticipate the opportunity to get the RSV vaccine once available.
No, you cannot swallow your tongue. This common myth persists, but the truth is that your tongue is anchored to the base of your mouth, which limits its movement.
During events such as seizures, while the throat may retract, other muscles kick in to keep the airway open, preventing the tongue from obstructing breathing.
Tragically, this misconception has resulted in fatalities. A 2025 survey revealed that attempts to stop athletes from “swallowing their tongue” during heart attacks led to death in two-thirds of cases.
In contrast, 74% of individuals will survive a heart attack if they receive defibrillation within 3 minutes.
This article was inspired by the inquiry: “Can I swallow my tongue?” submitted via email by Johnny Norris.

According to a recent study published in Pro Swan, the Chincha Kingdom, an influential ancient society on the Peruvian coast, thrived significantly due to their innovative use of bird droppings.
Archaeological investigations of maize recovered from burial tombs indicate that the Chincha people utilized seabird droppings, known as “guano,” as fertilizer to improve agricultural yields.
This natural fertilizer enabled the Chincha Kingdom to produce a corn surplus, facilitating economic growth, population expansion, and increased influence, ultimately making it one of the most prosperous Pre-Inca civilizations in South America.
“While seabird guano might seem insignificant, our study reveals that this vital resource played a crucial role in sociopolitical and economic transformations in the Peruvian Andes,” stated Dr. Jacob Bongers from the University of Sydney. “In ancient Andean cultures, fertilizer equated to power.”
Bongers’ team analyzed 35 corn samples from the Chincha Valley burial tombs, where an estimated 100,000 individuals lived at the time, discovering that the corn exhibited unusually high nitrogen levels.
Seabird feces are particularly nitrogen-rich due to their marine diet, providing biochemical evidence that the Chincha people enriched their soil with guano.

“The guano was likely sourced from the nearby Chincha Islands, renowned for their abundant and high-quality guano deposits,” Bongers elaborated.
The research team further examined modern images of seabirds, fish, and sprouting corn depicted on pottery, wall carvings, and paintings.
This artistic evidence reinforces the connection between seabirds and maize, highlighting their significant cultural role in Chincha society.
“The combined chemical and physical evidence we analyzed aligns with prior studies indicating that guano was intentionally harvested and utilized as fertilizer,” Bongers noted.
“Moreover, it underscores a deeper cultural significance, pointing to the acknowledgment of this fertilizer’s remarkable power and the ritualistic celebration of the bond between seabirds and agriculture.”

Much about the Chincha Kingdom’s history, including its origins, remains elusive, but it is known that it became part of the Inca Empire around 1480 AD, not long before the Spanish conquest of Peru.
Prior to their incorporation into the Inca Empire, the Chincha people engaged in trade with the Incas, who were known for their obsession with corn, which they fermented into a ceremonial beer called “chicha.”
However, the Incas, living high in the Andes, were unable to cultivate substantial corn crops due to their lack of access to valuable guano.
“Chincha’s true strength was not solely in resource access but in its mastery of complex ecosystems,” explained study co-author Dr. Joe Osborne from Texas A&M University.
“They possessed traditional knowledge of the interconnections between marine and terrestrial ecosystems, transforming that understanding into an agricultural surplus that built their civilization.”
“Their art reflects this connection, illustrating that their power stemmed from ecological wisdom, not just precious metals.”
Many people consider themselves rational thinkers, but would we truly change our views if presented with evidence that contradicts them? The answer isn’t straightforward.
Being wrong can elicit discomfort and even feelings of threat, which makes altering someone’s mindset more challenging than anticipated.
Consider those who believe in a flat Earth. Despite presented satellite images proving otherwise, they may still insist on their view. Engaging in debates often reinforces their original beliefs instead.
This phenomenon is known as the “backfire effect,” where conflicting evidence fortifies existing beliefs.
Such resistance to change is prevalent across various topics, from vaccine safety to the effectiveness of trendy diets.
What causes this difficulty in shifting perspectives? Recent studies in Trends in Neuroscience and Education reveal that conventional persuasion methods, like citing facts or emphasizing risks, often clash with our brain’s natural processing. Two crucial neuroscientific concepts enhance our ability to persuade others.
The first is reward prediction error. When outcomes exceed expectations, dopamine—the brain’s pleasure chemical—is released, encouraging repetition of that experience. Therefore, influencing someone’s beliefs often requires them to adopt new ways of thinking. However, if new information feels disappointing or threatening, changing their mindset becomes problematic.
The second concept is the subjective value of information. Our brains assign value based on relevance and reward perception. Information is deemed valuable when it aligns with our identity and aspirations.
If information seems irrelevant or threatening, individuals often disregard it. For instance, simply stating that smoking is dangerous may not be sufficient to persuade someone to quit.

People are more open to adjusting their beliefs when they view new information as emotionally rewarding, relevant, of high quality, and personally meaningful.
So, what can we glean about persuading others to reconsider their views? Dr. Bobby Hoffman, a psychologist specializing in motivation and learning at the University of Central Florida, suggests four effective strategies based on how our brains interact with new information.
1. Spark Curiosity
Gently challenge assumptions and pose questions that pique interest. For example: “Did you know that people who sleep early are often more focused during the day?”
2. Ensure Relevance
Connect your message to the individual’s goals and values. For instance, “I want to improve my focus at work. Did you know that consuming more fruit can enhance brain function?”
3. Emphasize Benefits
Highlight potential gains. “Cutting down on alcohol can safeguard your liver, enhance sleep, and aid in weight loss.”
4. Provide Choices
People react positively when they feel empowered, so offer options. “If you aim to be more active, consider taking a fitness class or adding regular walks to your routine.”
During your next debate with a family member or an effort to persuade a colleague, remember that changing beliefs involves more than just presenting facts.

Tomassini et al. characterized the physical and morphological properties of AFGL 4106, a binary star system of two evolved massive stars. Image credit: ESO / Tomassini et al..
“Before a star reaches the end of its life cycle, it expels massive amounts of gas and dust that contribute to the formation of a growing nebula,” stated Dr. Gabriel Tomassini from the Côte d’Azur Observatory and colleagues.
“The massive stars in the AFGL 4106 system are in advanced but distinct stages of their lifecycle, with one having shed enough mass to form a surrounding dusty envelope.”
In their recent study, the authors meticulously map this cosmic debris to identify the characteristics of AFGL 4106’s central star.
“Imaging objects near a bright star presents significant challenges due to the star’s overwhelming brightness. In fact, the central star appears black as its brilliance saturates the image detectors,” noted the researchers.
“Fortunately, the VLT’s SPHERE instrument excels at managing significant light contrasts, enabling detailed observation of both the luminous stars and their darker surrounding nebulae for the first time.”
“It also corrects for atmospheric turbulence, providing remarkably clear images.”
The nebula’s unique shape indicates that the companion star significantly affects the gas outflow from the dying star, introducing asymmetry and distorting the gas and dust cloud from a perfectly spherical shape.
“Our findings place constraints on the physical properties and evolutionary status of the system,” concluded the astronomers.
“This research enhances our understanding of mass loss processes in massive binary stars and the morphology of nebulae surrounding evolved stars.”
Results from this study are detailed in the journal Astronomy and Astrophysics.

New Study Reassesses the Age of the Jordan Valley Ubaydiya Layer: Dating Back Approximately 2 Million Years, Comparable to Georgia’s Dmanisi Ruins. This Research May Mark a Critical Moment in Human Evolution, Indicating That Early Humans with Advanced Tool-Making Skills Expanded into New Environments Much Earlier Than Previously Believed.

The Ubaydiya ruins are situated in Israel’s Jordan Valley, nestled between Menahemia village and Beit Zerah kibbutz.
Discovered in 1959, this site has yielded a distinctive Ature hatchet but only a few human remains.
“The Ubaydiya Formation has been a focus of research for years, offering early evidence of the Acheulean culture, recognized by its large, double-sided stone tools, often found alongside a diverse array of fauna, including species from Africa and Asia,” remarked Ali Matmon, a professor at the Hebrew University of Jerusalem.
“Yet, determining the precise age of this site has posed a considerable challenge over the decades.”
“Historically, researchers estimated Ubaydiya’s age to be between 1.2 and 1.6 million years, based on relative chronology.”
To ascertain the site’s true age, researchers employed three independent dating techniques: magnetic stratigraphy, uranium-lead (U-Pb) dating of mollusc shells, and cosmogenic isotope burial dating.
“Cosmogenic isotope burial dating measures rare isotopes generated when cosmic rays strike rocks on Earth’s surface,” explained the research team.
“Once buried, these isotopes decay at a known rate, effectively beginning a geological clock that indicates how long they have been underground.”
“We also analyzed remnants of Earth’s ancient magnetic field preserved in lake sediments at the site,” they added.
“As sediment settles, it locks in the orientation of the planet’s magnetic field at that time.”
“By correlating these magnetic signatures with known historical reversals in Earth’s magnetic field, we established that this formation emerged during the Matsuyama period, over 2 million years ago.”
“We also examined the fossils of melanopsis, utilizing U-Pb dating to determine the age of shells and freshwater snails within the sediment, which helped us establish the minimum age of the layer where the stone tools were discovered.”
“Overall, our findings indicate an age much earlier than previously anticipated.”

The team’s results indicate that the Ubaydiya site is at least 1.9 million years old, significantly older than prior estimates.
“This new chronology suggests that Ubaydiya is roughly contemporaneous with the renowned Dmanisi site in Georgia, implying that our ancestors migrated to different regions simultaneously,” the scientists noted.
“Additionally, this suggests that both simpler Oldowan and more advanced Acheulean stone tool-making techniques began their migration from Africa as various hominin groups explored new terrains.”
This groundbreaking study is published in the Quaternary Science Review.

Astronomers utilizing the NASA/ESA/CSA James Webb Space Telescope have made a groundbreaking discovery: they have identified a nearby supernova, specifically a red supergiant star, that was obscured by a thick layer of dust and remained invisible to prior observatories.
This striking image combines observations from both the James Webb Space Telescope and Hubble, focusing on spiral galaxy NGC 1637. It captures the evolutionary stages of the red supergiant star and reveals its transformation following the supernova event SN 2025pht. Image credit: NASA/ESA/CSA/STScI/C. Kilpatrick, Northwestern/A. Suresh, Northwestern/J. DePasquale, STScI.
The supernova event, designated SN 2025pht, was first identified in NGC 1637 on June 29, 2025.
In response, astronomers dedicated substantial resources to investigating this supernova.
However, Northwestern University’s astronomer Charlie Kilpatrick and his team chose to explore archival data, analyzing pre-supernova images to determine which star exploded.
A 2024 image of NGC 1637 captured with Webb’s MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera) highlights a distinct red supergiant star positioned precisely where SN 2025pht is currently visible.
“We anticipated this moment, hoping for a supernova to occur in a galaxy that Webb was already monitoring,” stated Dr. Kilpatrick.
“By integrating the Hubble and Webb datasets, we unveiled the star’s complete characteristics for the first time.”
“This red supergiant represents the dustiest star we have ever observed transitioning into a supernova,” noted Aswin Suresh, a graduate student at Northwestern University.
This dust anomaly may help solve a persistent mystery in astronomy: the absence of certain red supergiant stars.
Astronomers expect that the most massive stars should explode as the brightest supernovae, making their identification in pre-explosion images straightforward. However, this has not been the case.
One possible explanation is that these massive, aging stars are often heavily surrounded by dust, rendering their light invisible.
Observations from Webb regarding SN 2025pht seem to support this hypothesis.
“I have advocated for this interpretation, but I didn’t expect the outcome to be as pronounced as in the case of SN 2025pht,” commented Dr. Kilpatrick.
“This might clarify the absence of these heavier supergiant stars, as they tend to be engulfed in more dust.”
The team also discovered that the dust enveloping the star is likely rich in carbon—an unexpected finding, as silicate-rich dust is typically anticipated in these environments.
They speculate that this carbon may have been released from the star’s core shortly before the explosion.
“Mid-infrared observations were crucial in identifying the specific type of dust present,” Suresh added.
For more in-depth details on this discovery, view the team’s research paper published in October 2025 in the Astrophysics Journal Letter.

Researchers in Brazil have unearthed a newly identified species of vertebrate sauropod dinosaur resembling those from Europe, hinting at an ancient migration route that once linked two continents, now divided by the Atlantic Ocean.

This newly discovered dinosaur species lived approximately 120 million years ago during the Early Cretaceous period, a time when the world’s landmasses were consolidated within the southern supercontinent Gondwana.
Dubbed Dasosaurus tocantinensis, this dinosaur measured about 20 meters (66 feet) in length.
It belonged to the Somphospondyli clade, which includes titanosaur-like sauropods that thrived from the late Jurassic to the end of the Cretaceous period.
The partial skeleton of Dasosaurus tocantinensis was unearthed in the Itapecur Formation located in northeastern Brazil.
This dinosaur features distinct anatomical traits, such as elongated ridges and grooves on its caudal vertebrae, as well as a notably pronounced lateral bulge on its femur, characteristics not previously identified in any known species.
These unique features indicate that Dasosaurus tocantinensis lies outside the titanosaur lineage, a subgroup of sauropods that would later dominate the southern continents.
Interestingly, this new species appears most closely related to Galumbachitan morelensis, another sauropod that existed in present-day Spain around 122 million years ago.
The discovery not only catalogs a new species but also reinforces the idea that Early Cretaceous South America was not an isolated evolutionary niche.
Instead, it formed part of a vibrant network of land connections that facilitated dinosaur migrations between continents long before the Atlantic Ocean was fully formed.
“This finding expands the known diversity of Early Cretaceous sauropods in northern South America and underscores their biogeographical ties to Europe and other regions in northern Gondwana,” stated lead author Max Langer from the University of São Paulo and colleagues.
“Indeed, numerical biogeographical analyses suggest that a clade consisting of Dasosaurus tocantinensis and Galumbachitan morelensis originally arose in Europe, with their lineages migrating from Europe to South America through North Africa during the Valanginian (137 to 133 million years ago) and Aptian (121 to 113 million years ago) periods.”
The discovery of Dasosaurus tocantinensis was reported in a research paper published on February 12th in the Journal of Systematic Paleontology.

Horses are unique in their vocalizations, producing two distinct sounds simultaneously—a low, cow-like moo and a high-pitched whistle from their throats.
Recent research reveals that horse vocalizations exhibit both low-frequency sounds around 200 hertz and high-frequency sounds exceeding 1,000 hertz, a phenomenon known as biphonation. The low-frequency sounds can be attributed to the vibrations of the horse’s laryngeal vocal folds, much like human speech and singing. However, the mechanism for producing the high-frequency sounds in such a large animal remains an intriguing question.
“Humans have coexisted with horses for over 4,000 years, yet equine communication remains partially misunderstood,” explains Tecumseh Fitch from the University of Vienna, Austria.
To investigate this phenomenon, Fitch and his team conducted tests and experiments on horse larynxes sourced from meat suppliers.
“Initially, we observed low-frequency sounds when we blew air into the larynx,” says Fitch. “However, after some adjustments, we successfully elicited high-frequency components.”
This established that both sound components originate from the larynx itself, contrasting with human whistling produced via the lips.
To confirm the whistling mechanism, researchers introduced air and helium—two gases of varying densities—through the larynx. This allowed them to test whether high-frequency sounds resulted from whistle production or tissue vibrations.
“The low-frequency sounds stem from vocal cord vibrations, similar to human singing or cow mooing, and remained unchanged when we altered the gases,” Fitch noted. “Conversely, the high-frequency content varied significantly with higher helium concentrations.”
Endoscopic examinations of live horses revealed that laryngeal muscles contract as the call begins, narrowing the glottis—where the vocal cords reside—and increasing airway resistance. This mechanism forces air through a narrow opening at high speed.
While other small mammals like mice and rats can produce laryngeal whistles, their frequencies are inaudible to humans.
“Horses are unique among mammals for their ability to produce two frequencies at once using their larynx, with whistles being part of their regular vocal repertoire,” Fitch adds.
This research sheds light on a previously undocumented method of aerodynamic whistle production in animals beyond rodents, explains Ben Jankovic at the University of New South Wales, Sydney.
Fitch and his colleagues propose that whistles enhance vocal clarity and transmission distance, although these theories require further investigation.
The parasitic species Temnothorax kinomurai targets the closely related ants, Temnothorax makora.

In a groundbreaking discovery, researchers have identified a unique parasitic ant species in Japan that has effectively eradicated both male and female worker ants from their colonies. This means that all individuals in these colonies function as queens, attempting to dominate the nests of competing species.
Typically, ant colonies are structured with a queen, female workers, and short-lived males that die shortly after mating.
For over four decades, scientists have speculated about the existence of this elusive parasitic ant, Temnothorax kinomurai, which is known to produce only queens. Until now, however, there was no definitive proof.
Young queens of this parasitic species infiltrate the nests of closely related ants, Temnothorax makora, killing the host queen and some workers through stinging. They then reproduce asexually, creating cloned offspring in a process called parthenogenesis—a phenomenon that is rare among ants but common in other insect species. As a result, workers from T. makora are deceived into nurturing the young kinomurai queens.
Research led by Jurgen Heinze and his team at the University of Regensburg, Germany, successfully bred and raised T. kinomurai queens in a controlled laboratory environment, resulting in 43 queen offspring—none of which displayed male reproductive organs.
The resulting 43 queens were then introduced to colonies of T. makora. Out of these, seven queens survived and successfully executed their takeover, producing 57 additional offspring, all confirmed to be female queens.
“This discovery reveals a completely new form of social organization among ants, adding a fascinating dimension to the already complex world of ants,” Heinze states.
While invading the colonies of other species can be a precarious tactic—evidenced by the study’s high queen failure rates—having an all-female offspring increases the likelihood of establishing a new reproductive colony.
“If parthenogenesis arose through random mutation, this is the outcome. A single T. kinomurai queen can produce 100 daughters without the need for mating, leading to 100 queens ready to seek out new colonies,” Heinze explains.
“This species represents the pinnacle of social parasitism evolution, showcasing the remarkable adaptability in the life cycles of social insects,” he concludes.

Recent research on enigmatic symbols engraved on artifacts from Germany indicates that Stone Age humans, around 40,000 years ago, utilized a rudimentary form of writing. This discovery could potentially delay the timeline for the emergence of primitive writing systems by over 30,000 years, paralleling early cuneiform scripts.
Early Homo sapiens, particularly after migrating to Europe about 45,000 years ago, began to make intentional marks on various objects. These included pendants, tools, and intricately carved figurines adorned with graphic symbols—ranging from lines and crosses to dots. These groups also illustrated symbols on cave walls alongside animal representations, and their meanings remain a subject of scholarly debate.
“The systematic arrangement and repeated use of distinct symbols mark a notable advancement,” explains archaeologist Eva Dutkiewicz from the Museum of Prehistory and Early History in Berlin, Germany.
The overarching question concerns the meanings behind these ancient symbols. Without a ‘Rosetta Stone’ equivalent, deciphering their significance is complex; however, studying their application offers valuable insights.
To delve deeper, Dutkiewicz and linguist Christian Benz from Saarland University analyzed markings on artifacts unearthed in the Swabian Jura region, dating between 43,000 and 34,000 years ago, during the Aurignacian period. They examined 260 artifacts, including flutes and animal-human hybrid figurines, which featured 22 different symbols over 3,000 times, primarily employing a V-shaped notch, lines, crosses, and dots.
The researchers employed computer models to assess the complexity and density of information encoded in these sequences. By comparing these patterns to modern scripts and Protocuneiform—Mesopotamia’s oldest known writing dating from 3500 to 3350 BC—they aimed to identify parallels between Stone Age markings and later systems of communication.
“Information can be encoded through the variety and combination of symbols,” says Benz, noting that even the 26 letters of the English alphabet can generate extensive meanings through different arrangements.
The analysis indicated a clear distinction between Aurignac symbols and contemporary letters. Surprisingly, the statistical properties of these 40,000-year-old symbols closely resemble those found in early proto-cuneiform tablets. “Their characteristics show notable similarity,” Benz remarks.
This discovery suggests that early Homo sapiens in Europe may have developed a symbolic recording system, aligned with one definition of writing: a visual communication method using established markings.
“The study indicates that the markings from the Aurignac period mirror a compositional style akin to proto-cuneiform,” states paleoanthropologist Geneviève von Petzinger. “They exhibit repetition and organization.” Yet, this does not imply that both systems shared identical meanings.
While cuneiform originated primarily for accounting purposes—such as recording crop amounts—the question arises about the meaning of “writing” in the Stone Age. Some markings on Aurignac artifacts hint at potential calendrical functions. For instance, an ivory plaque featuring a lion-human figure called Adorant showcases sequences of dots that may represent “calendar observations,” Dutkiewicz suggests, noting their likely interest in tracking time.
Dutkiewicz and Benz further analyzed object symbol usage, revealing intriguing patterns. Despite the cross being common, it was never used on human depictions but frequently found on animal and tool carvings, especially relating to horses and mammoths. Conversely, dots were absent from tool representations.

“While we cannot definitively interpret the meanings, a consistent pattern suggests deliberate choices in symbol application,” Dutkiewicz notes. Additionally, the consistency in these markings over millennia points to a tradition that was likely transmitted across generations.
“These markings were intentionally placed and had significance for the creators,” observes von Petzinger. “Their exact meanings, however, remain elusive.”
This research builds upon a 2023 study suggesting that sequences of dots and lines accompanying cave paintings, allegedly encoding predator behaviors, hint at early systems of recordkeeping.
Overall, while cuneiform emerged around 3200 BC as the first comprehensive writing system, its roots could trace back as far as 40,000 years.
Illustration of the Iron Age Mass Grave at Gomolava

In a groundbreaking discovery, evidence suggests that women and children were intentionally targeted in the largest prehistoric mass murder ever found in Europe. The 77 victims, buried over 2,800 years ago, appear to have died from brutal violence.
This significant mass grave was unearthed at Gomolava, an early Iron Age site located in the Carpathian Basin of modern-day Serbia. The site is characterized by a man-made mound, known as a tell, formed through layers of debris accumulated over thousands of years of human habitation since the late 6th millennium B.C. Archaeological findings also include remnants of adobe structures, pottery, and organic materials.
Research led by Linda Fibiger and her colleagues at the University of Edinburgh analyzed skeletal remains sourced from cemeteries at the Vojvodina Museum in Novi Sad, Serbia, employing DNA and isotope studies to shed light on these ancient events.
Of the 77 individuals, 51 were identified as children and adolescents. Biological sex was ascertained for 72 of the individuals, revealing that 51 were female.
Initial assessments in 1976 had misattributed the cause of death to a pandemic; however, new analyses revealed unhealed injuries consistent with violent acts, including defensive wounds and projectile impacts.
“Many injuries were to the head, indicating forceful contact. The prevalence and nature of these wounds suggest intentional killing rather than accidental death,” Fibiger remarked. “This incident appears to be exceptionally brutal.”
The research team analyzed DNA from the remains of 25 individuals and studied the ratios of strontium, oxygen, and carbon isotopes found in the tooth enamel of 24 victims. This analysis helps reconstruct childhood environmental conditions and revealed that the individuals were often not closely related and had diverse diets in their youth.
“Most were not even related within the last 12 generations,” asserted Barry Molloy from University College Dublin, Ireland. He posits that the victims were part of a broader societal structure that shared cultural practices without necessarily forming close-knit groups.
This horrific genocide occurred during the 9th century BC, coinciding with the migration of nomadic pastoralists from the Eurasian steppes, while local populations were reestablishing old settlements and agricultural practices. Molloy highlighted the potential for conflicts over land rights during this transitional period, which could have led to such violent outcomes.
“The targeting of women and children suggests a different motive than what we typically associate with warfare,” Molloy explained. “It points toward a calculated strategy to assert control or quell dissent.”
There is speculation that perpetrators may have aimed to undermine resistance by killing young children, previously considered for enslavement, sending a strong message to nearby tribes.
Interpreting genocide is complex,” noted Pere Gelabert of the University of Vienna, Austria. “The Iron Age was marked by regional instability and conflict. Mass burial practices may reflect ritualistic massacres, focusing on women and children, or result from men being absent during such violent occurrences.”
Interestingly, the burial sites contained personal artifacts like bronze jewelry and ceramic vessels, along with animal remains and crushed stones, suggesting a careful and symbolic burial process. “This implies distinct groups carried out the killings and the funerals,” Molloy concluded.
How Birdwatching Can Enhance Your Cognitive Reserve
Steve Young/Alamy
Recent research suggests that birdwatchers exhibit distinct brain differences that could explain their remarkable skill in identifying unfamiliar birds. This indicates that engaging in birdwatching may alter brain structure, akin to the effects of learning a new language or musical instrument. Such activities are believed to enhance cognitive reserve—the brain’s capacity to combat aging and adapt to damage.
As individuals learn or practice new skills, neural pathways in the brain reorganize, strengthening relevant connections. This phenomenon, known as neuroplasticity, facilitates the acquisition of specialized knowledge. For example, professional musicians display structural changes in brain regions associated with auditory processing, while athletes experience similar adaptations in their motor cortex.
To explore the effects of birdwatching on brain structure, Eric Wing and his team from York University, Canada, examined the brain function and structure of 48 recreational birdwatchers, with participants categorized into experts and beginners. The age range of participants was between 22 and 79 years, ensuring balanced variables like gender, age, and education.
During brain scans, participants viewed bird images for less than four seconds. Following this, they attempted to identify the same bird from four options, each depicting a different species. “We purposefully selected bird species that were quite similar,” states Wing.
This identification task was done 72 times, utilizing images from 18 distinct bird species—six being local and twelve non-native.
As anticipated, expert birders outperformed novices, with an average correct identification rate of 83% for native bird species and 61% for non-native; novices, on the other hand, correctly identified only 44% of the birds.
Notably, while identifying non-local birds, activity increased in three key brain regions for expert birders, including the bilateral prefrontal cortex, bilateral intraparietal sulcus, and right occipitotemporal cortex—regions pivotal for object recognition, visual processing, attention, and working memory. “This illustrates the diverse cognitive processes involved in bird watching,” Wing explains.
Moreover, these areas exhibited greater structural complexity and organization in expert bird watchers compared to novices, indicating that developing expertise in birdwatching may reshape the brain.
As we grow older, the complexity and organization of brain structures typically diminish, a trend observed in both novice and expert birdwatchers. Nonetheless, the decline appeared less significant in birdwatchers, suggesting that engaging in birdwatching contributes to building cognitive reserve, enhancing the brain’s resilience against aging.
“This implies that staying mentally active in specialized areas may help mitigate the effects of aging,” asserts Robert Zatorre at McGill University in Canada. “While this has been a controversial topic, this paper provides new evidence that supports this concept.”
Broadly participating in other hobbies that demand similar skills—like attention, memory, and sensory integration—may drive comparable brain changes. Wing notes, “Birdwatching taps into numerous cognitive domains, potentially benefiting various cognitive abilities. However, the cognitive enhancement might not be exclusive to birds; if other activities engage similar processes, we could expect similar brain changes there.”
Nevertheless, this study reflects merely a snapshot in time. It’s possible that structural changes occurred prior to participants taking up birdwatching, or that other lifestyle factors leading to brain changes are more prevalent among birdwatchers. To determine if brain changes are directly linked to birdwatching, longitudinal studies involving multiple scans over several months or years are necessary, Wing asserts.
When a homicide detective in California’s Central Valley resumed her investigation into the unsolved murder of a bakery owner last year, she utilized an increasingly popular forensic tool that has been instrumental in solving numerous cases across the nation. Recently, infections have spread across the United States and Canada, drawing attention to public health concerns.
Kern County Sheriff’s Office Detective Ashley Sanchez expressed confidence in having pivotal evidence that could lead to identifying those responsible for the tragic 2010 death of 49-year-old Juanita Francisco. However, securing funding for the essential genetic genealogy research proved to be a significant challenge, Sanchez noted.
After all, the finances for such efforts do not stem from local taxpayers or government subsidies; crowdsourcing fundraising initiatives became the solution.

This unique funding model highlights the challenging economic reality for many seeking to leverage the method, which gained traction following the apprehension of the “Golden State Killer” eight years ago and has resolved over 1,600 cases across the United States and Canada. According to a report updated earlier this year, compiled by a criminology professor at Douglas University in Canada.
Authorities looking into the potential kidnapping of Nancy Guthrie are also considering this methodology, which integrates traditional genealogy with cutting-edge DNA analysis, as a means to address unsolved crimes and unidentified remains.

David Gurney, director of the Center for Investigative Genetic Genealogy at Ramapo University in New Jersey, highlighted that some government funding does exist, but the financial aid provided by states and federal authorities “barely scratches the surface.”
This underscores the reliance on crowdfunding as a feasible solution. Canadian criminology expert Tracy Dowswell estimates that approximately 120 of the 1,600 cases cataloged involved crowdfunding, but suggests this figure may be an underestimate, as many cases can receive funding from multiple sources, primarily those involving unidentified bodies.
Numerous additional cases are showcased on platforms like DNA Doe Project, Moxy Forensic Investigation, and DNA Solves — where Francisco’s fundraising initiatives are prominently featured. This crowdfunding strategy has seen success, although some cases remain unresolved, and others await funding.
“It’s remarkable to see how willing the public is to contribute to these cases,” remarked Gurney. “Nonetheless, this model is not sustainable for the criminal justice system.”
David Mittelman, CEO of Osram, the Texas-based DNA lab collaborating with DNASolves, noted that the site serves as a repository for many of their cases. “It’s nearly impossible to investigate—not due to a lack of evidence or interest, but rather the absence of a funding channel,” he stated.
Gurney emphasized that the need for crowdfunding illustrates the lack of recognition for genetic genealogy as a tool for solving America’s cold cases. Federal data indicates that this technique could potentially unravel hundreds of thousands of unsolved violent crimes and tens of thousands of unidentified remains cases.
“Without increased funding, expanding this effort to tackle the backlog of cold cases will remain challenging,” Dowdeswell stated.
Just a Handful of Labs
Genetic genealogy relies on several critical components. Researchers require a DNA sample and profile of the person they aim to identify. This profile needs to be uploaded to GEDMatch or FamilyTreeDNA, consumer DNA databases accessible for law enforcement purposes. The acquired profile can then be used to construct a family tree and trace the origins of unidentified DNA.
However, acquiring a quality profile can be challenging, as DNA samples often tend to be old and degraded, noted Kendall Mills from Season of Justice, a nonprofit dedicated to funding advanced DNA analysis for law enforcement agencies lacking the necessary resources.
Only a select few private labs in the United States, such as Osram, possess the capability to undertake the work required to develop these profiles, Mills added.
“Private labs typically utilize more advanced and sensitive technologies,” she explains. “They also have the capacity to conduct extensive research and development that public labs funded by taxpayer dollars often lack, but this expertise comes with a hefty price tag.”
Gurney mentioned that accessing consumer DNA databases comes with a price starting at $1,000 or higher.
He added that some state and federal agencies have initiated work on the labor-intensive genealogical research that will follow, yet much of this work relies on support from a diverse array of nonprofit organizations, private companies, and at least one academic institution (Ramapo).
Organizations like Ramapo and the DNA Doe Project, a groundbreaking nonprofit that has collaborated with law enforcement and coroners to solve over 150 cases using genetic genealogy, rely on networks of volunteers to contribute some or all of their genealogical work pro bono. Some companies, such as Othram, provide in-house services for a fee.
Mittelman pointed out that only a small number of Osram’s genealogy projects utilize crowdfunding; the company usually depends on a mix of state and federal grants, philanthropic donations, and nonprofit funding. Currently, DNASolves features dozens of cases from across the country that have successfully generated crowdfunding, with a few more aiming for a funding goal of $7,500 that remains unmet. Dowswell noted that he has documented 40 cases resolved through the site.
Mittelman shared that DNASolves was initially created to showcase case results, but as law enforcement agencies faced budget constraints for forensic work on high-interest cases, the company launched a successful crowdfunding campaign.
Gurney noted that the Ramapo center does not require crowdfunding, as its operations are financed through an educational component (the center offers certificates in genetic genealogy) and donor contributions.
In contrast, crowdfunding is vital for the DNA Doe Project, according to its communications director, Matthew Waterfield.
Waterfield believes that the primary hurdle to advancing genetic genealogy is the escalating costs associated with research and upload fees tied to the DNA databases essential for researchers.

Waterfield recounted a case concerning an unidentified elderly woman discovered in a shallow grave in Arizona, which needed nearly $5,000 in funding to cover lab and database access fees. Raising the necessary funds took months. Through the “Doe-Nate” site, he added that with a DNA profile upload, a network of volunteer genealogists could solve a case in as little as eight hours.
“I wish I could say this was an isolated incident, but it’s not,” Waterfield noted. “There have been many instances where significant time was spent raising funds, but once secured, our volunteers have solved cases in mere hours, days, or weeks, bringing closure to families for the first time in decades.”
If more funding were accessible, Waterfield emphasized, “we would witness countless cases being resolved right now.”
Claim Federal Funding
To combat the financial challenges in this sector, Osram is advocating for the Carla Walker Act, a federal law proposing $10 million annually in grants to law enforcement agencies unable to perform genetic genealogy research internally. It also aims to cover equipment enhancements for public crime labs to begin conducting forensic investigations independently.
“Neither one company nor ten can resolve the multitude of cases,” Mittelman stated. “What’s essential is the collaboration of hundreds of labs utilizing the latest technologies.”
Waterfield confirmed that the DNA Doe Project backs the legislation, which enjoys bipartisan support in both the House and the Senate. He believes the provisions in this funding legislation could help reduce research costs by giving law enforcement agencies a variety of options for genetic genealogy researchers.
Detective Sanchez, who has found herself raising funds for cold case investigations, stated this was something she never expected to do. She participated in a comprehensive video about the case released by her department in November and gave an interview on a true crime show’s livestream in December.
The fundraising campaign for Juanita Francisco’s case was launched on November 21st and reached its funding goal by early January.
Sanchez expressed relief, stating that she can now refocus on her investigation and is hopeful that new leads will help identify Francisco’s killer.
Becoming a birdwatching expert transcends mere hobby; it’s a transformative activity that can significantly enhance brain structure and function. Recent studies reveal that engaging in birdwatching may promote cognitive improvements, even as we age.
In a study conducted in Canada with 58 participants, brain imaging showed that expert birdwatchers exhibited increased tissue density in regions linked to attention and perception compared to novices. This heightened density suggests enhanced communication between neurons, which correlated with superior bird identification skills.
Lead author Eric Wing, while a postdoctoral fellow at the Rotman Institute of Baycrest Academy of Research and Education in Toronto, states, “Our brains are incredibly malleable.”
Learning a new skill triggers neuroplasticity, the brain’s ability to reorganize itself. While previous research has focused on professionals like athletes and musicians, Wing’s team aimed to study birdwatchers due to the unique cognitive challenges birdwatching presents.
“Birdwatching combines fine discrimination, visual searching, environmental attention, movement sensitivity, and intricate pattern detection,” Wing explained. “It also requires recalling what we’ve seen and comparing it to internal cognitive templates.” He is now a researcher at York University in Toronto.
MRI Scans Reveal Brain Differences
The study included 29 expert birdwatchers aged 24 to 75, recruited from organizations like the Toronto Ornithological Club and Ontario Field Ornithologists. Novices ranged from 22 to 79 and were from similar outdoor or hiking clubs.
While some participants had decades of birdwatching experience, expertise was assessed through screening tests rather than time spent birding.
During a bird matching task, experts demonstrated superior accuracy in identifying both local and exotic bird species compared to novices.
Surprisingly, Wing noted distinct neurological activity among the expert birdwatchers.
The researchers employed two types of MRI scans—diffusion and functional—to assess the participants’ brains.
Diffusion MRI revealed greater density in brain areas involved in working memory, spatial awareness, and object recognition among experts.
Functional MRI data highlighted active regions in expert brains during bird-matching tasks, especially when identifying unfamiliar species.
“These findings offer insights into the significance of these brain regions in developing expertise,” Wing noted. “Such skills are crucial for recognizing new and unidentified bird species.”
Cognitive Benefits for Older Birdwatchers
Experts showed structural brain differences irrespective of age. Though this study doesn’t definitively prove birdwatching prevents cognitive decline, it does suggest potential benefits for brain health in older adults, according to Molly Mather, a clinical psychologist from the Meshulam Institute for Cognitive Neurology and Alzheimer’s Disease at Northwestern University’s Feinberg School of Medicine.
“As populations age in the U.S. and globally, we lack treatments to halt or reverse aging and Alzheimer’s-related changes,” Mather, who wasn’t involved in the study, emphasized. “Establishing a scientific basis for recommendations is invaluable.”
Mather noted a chicken-and-egg dilemma in this study: Do brain differences stem from birdwatching, or do individuals with certain neural traits become adept birdwatchers?
Moreover, participants were drawn from active outdoor groups, potentially reflecting healthier lifestyles.
Benefits of Nature Engagement
Benjamin Katz, an associate professor at Virginia Tech’s Department of Human Development and Family Sciences, pointed out that other factors in birding could enhance brain health. Immersion in nature boosts alertness, walking mitigates cognitive decline risk, and social interactions might expedite processing speed.
“Birdwatching isn’t a one-dimensional activity,” Katz, also not part of the study, remarked. “Numerous cognitive factors are involved.”
Katz urged that future research should track novice birdwatchers over time to observe potential brain changes as they gain expertise.
“We lack clarity on baseline differences,” he pointed out. “Long-term data is essential for strong conclusions regarding the impacts of birding.”
The study authors suggested their methodology could explore brain reorganization related to other complex skills.
“Our passions and experiences, especially those cultivated over countless hours or years, leave a lasting imprint on our brains,” Wing concluded. “Identifying ways to leverage this accumulated knowledge can bolster cognitive function.”
Professor Hannah Fry introduces her new program, AI Confidential, which delves into the most significant narratives emerging from the forefront of the AI revolution.
This compelling three-part documentary series begins on Monday, February 23, on BBC Two, and follows individuals who utilize AI to replicate their deceased loved ones or to enhance driving experiences with the semblance of friends and family. We had the opportunity to chat with her to gain further insights.
What is your perspective on artificial romance?
While I personally wouldn’t engage, I find it to be a fascinating spectrum. It resembles interactive romantic fiction, which isn’t inherently wrong.
On one end, you might fully believe that the AI you’re interacting with embodies the essence of the person you love, while on the other, it can simply enhance your imagination. Ultimately, it’s not entirely negative.
Are we nearing a future where AI may replace human relationships?
I can’t definitively say it will happen, but there’s a possibility it might.
Society seems increasingly isolated; social interactions have shifted, with more individuals working from home and spending less time outside.
The emergence of personal friendships with AI could exacerbate this trend.
What concerns you most about AI?
AI holds the potential to alienate us from our humanity and hinder genuine connections. Unlike self-driving cars, the subtle dangers of AI distancing us from our relationships can be more insidious.
While AI is being integrated into therapy, there’s a danger that it reinforces our existing beliefs, leading to greater isolation.
After producing this series, I realized how easliy this could manifest. Using an AI as a therapist during conflicts may lead to a skewed perspective that you’re solely in the right.
In contrast, a human therapist encourages you to consider different viewpoints. AI isn’t designed to tackle complex emotional issues; it can make self-radicalization all too easy. When engaging with AI, I often ask, “Please tell me when I’m wrong; I need a challenge.”

Can chatbot technology fill the void of loneliness?
Absolutely. However, if we dismiss the idea that AI can serve as therapists or empathetic companions, we risk overlooking the needs of the lonely and vulnerable. While in an ideal world, everyone would have meaningful connections, that is not our reality.
In AI Confidential, you meet Justin Harrison, who has developed AI capable of mimicking voices, allowing communication with departed loved ones. What are the implications of this grief technology?
It’s disconcerting that such technology targets people during their most vulnerable moments.
Initially, I was skeptical of Harrison’s perspective on grief, which suggested we should eliminate sadness entirely, reflecting an inability to accept death. This approach seemed irresponsible to me.
However, as I contemplated my own recent loss, I understood how this technology could be an extension of what people often do to cope with longing for loved ones. It could provide comfort at acute stages of grief, especially in cases of unexpected loss.
Although I didn’t anticipate becoming emotional on camera, sharing that moment was crucial, as it illustrated our deeply human story. Ideally, AI should enhance our humanity, not detract from it.
That moment deepened my empathy for those who experience isolation. We all seek connection.

Will AI ultimately dominate the world?
Not if I have anything to say about it!
AI presents significant challenges, but when managed responsibly, it can serve as a powerful tool for good.
Currently, AI acts as a catalyst, streamlining tasks and enhancing skills. Many individuals benefit from using AI for educational purposes, making learning more efficient and developing new abilities.
AI could also lead to breakthroughs like unlimited clean energy or fresh water for all. We could even transform desert areas into flourishing ecosystems.
Humanity has largely existed in a world marked by scarcity, but with advances in AI, we may unlock realms of abundance, offering solutions to various ailments and societal challenges.
While these transformations won’t happen overnight, the potential remains significant.
How can we ensure AI benefits society?
Companies can take proactive steps, such as recognizing signs of distress or AI dependency during interactions.
We should prioritize concerns around AI, as awareness drives change.
