Long-term drought has significantly contributed to the Great Salt Lake’s decline, but approximately 75% of the issue stems from human activities. According to research published in 2022, excessive water consumption by humans has taken a toll over the decades.
In 2022, state officials took decisive action to address the crisis. Lawmakers allocated $40 million to establish a water trust aimed at enhancing both water quality and quantity. Additionally, alterations to Utah’s water law now designate it as a “beneficial use” for farmers to redirect their allotted water into lakes, incentivizing donations and water transfers. Previously, any unused water rights could be lost.
National authorities also initiated modifications along the causeway dividing the lake’s northern and southern sections, enabling control over water and salt flow. Fortunately, this winter brought about double the normal snowfall in the mountains, which played a key role in the lake’s recovery.
Kevin Perry, an atmospheric scientist at the University of Utah specializing in the Great Salt Lake and its toxic dust, noted that these combined factors significantly lowered the lake’s salinity, effectively “saving it.”
According to Perry, “That huge snowpack buried and diluted all the salt in the southern part of the lake.”
The ecosystem is showing signs of recovery; “The seeds are back,” Perry remarked.
Baxter added, “This year’s flies were just tough.”
These changes were enough to temporarily avert a crisis, at least for now.
Joel Ferry, director of the Utah Department of Natural Resources, expressed relief, stating, “We dodged an environmental nuclear bomb. We put away the red button.”
However, water levels have yet to return to a healthy state, and the potential impact of this year’s excessive snowfall continues to pose challenges.
It’s astonishing that we have more detailed maps of the moon than of our deep ocean floor. The moon’s surface is easier to observe, as it lacks the vast deep ocean that obscures our view of Earth’s underwater terrain.
With a telescope on a clear night, anyone can glimpse the moon’s features, especially on the side visible from Earth. Interestingly, the moon is roughly one-tenth the size of the deep ocean floor, which encompasses two-thirds of our planet’s surface.
The deep ocean covers an extensive area of over 335 million square kilometers (approximately 129.3 million square miles). Its inaccessibility, combined with the vastness of the ocean, explains why, despite our advanced technology, only a fraction has been explored.
Recently, a dedicated team of scientists compiled a comprehensive dataset containing data from around 44,000 dives into the deep ocean. These dives were conducted using submarines, remotely operated vehicles (ROVs), and autonomous underwater robots.
These deep-diving vehicles have collectively documented less than 0.001% of the deep-sea floor, comparable to the area of Rhode Island, the smallest U.S. state. If we applied similar statistics to terrestrial exploration, our entire understanding of ecosystems would come from an area only as large as the London metropolitan region.
Moreover, the minuscule part of the ocean floor studied is a highly biased sample. In fact, 65% of deep-sea exploration dives happened within 200 nautical miles of the United States, Japan, or New Zealand. Nearly all deep-seafloor observations (around 97%) were conducted by these three countries, in addition to France and Germany.

Additionally, explorers have mainly concentrated on a narrow spectrum of deep-sea features, dedicating significant research to rugged marine landscapes such as deep canyons and cliffs while neglecting regions like the expansive abyssal plains.
The Global Dive Dataset also highlights a critical limitation: dive depth. While the number of dives has increased over the decades, the depths have generally become shallower. In the 1960s, over half of dives surpassed 2 km (about 1.2 miles) deep, but by the 2010s, only a quarter of dives reached that depth.
This is concerning because approximately 75% of the ocean lies between 2 km and 6 km (1.2 miles and 3.7 miles) beneath sea level, indicating that significant portions of the ocean floor remain uncharted.
Clearly, contemporary deep-sea explorations overlook vast areas, leaving much of the ocean unexplored and unknown. Various initiatives are underway to enhance access to deep-sea tools and dive into less-known locations to discover what lies beneath the global deep ocean.
This article responds to Charlotte Preston of Southampton, who asked: “How much of the ocean floor have we actually explored?”

When AlphaGo showcased its capabilities, the world took notice. Lee Sedol, the top Go player globally, was visibly unsettled by the rise of artificial intelligence. The audience in downtown Seoul, South Korea, was captivated, realizing that this AI was groundbreaking.
Not only did AlphaGo defeat Lee, but it did so with a level of skill that resembled human intuition. “AlphaGo actually has intuition,” stated Sergey Brin, co-founder of Google, right after AlphaGo secured a 3-0 victory. “It creates beautiful movements, even more so than many humans expect,” New Scientist.
The match concluded with AlphaGo triumphing 4-1, leaving Mr. Lee in disbelief.
Ten years have elapsed since this pivotal event marked a turning point for AI. As we now celebrate advancements in large-scale language models like ChatGPT, it’s remarkable to reflect on how AlphaGo was a precursor to today’s AI. What remains of AlphaGo’s legacy, and is the technology fulfilling its promise?
“While large language models differ fundamentally from AlphaGo, there are crucial technological connections that have persistently evolved,” notes Chris Madison, a professor at the University of Toronto and a member of the original AlphaGo development team.
The core technology driving AlphaGo is neural networks, mathematical structures inspired by the brain, coded for machine learning. Historically, programming machines to play games required humans to dictate rules. Neural networks allow machines to learn independently.
However, mastering Go with neural networks presented a significant challenge. The ancient game allows for 10171 possible positions on a 19 x 19 board, dwarfing even the estimated 1080 atoms in the observable universe.
This breakthrough emerged when Madison and his team aimed to emulate human intuition by training a neural network to predict optimal moves based on millions of historical game moves. Humans develop intuition without such extensive data, providing AI a competitive edge.
Furthermore, AlphaGo wasn’t limited to human gameplay; it could play millions of self-matches to refine its capabilities. “Through countless matches, we can uncover new strategies that surpass human performance,” explained Pushmeet Kohli, a leader at Google DeepMind.
The final version of AlphaGo that triumphed over Lee was more intricate than Madison’s original model, but the conclusion was clear: neural networks excel at pattern recognition and can possess an intuition that surpasses human understanding, according to Norm Brown from OpenAI.
The Next Iterations of AI
What followed after AlphaGo? Google DeepMind and AI researchers began applying the foundational lessons from AlphaGo to real-world problems, including mathematics and biology. A prominent example is AlphaFold, which can predict protein structures in three-dimensional space from their chemical makeup, earning its creators a Nobel Prize in Chemistry.
Recently, another neural network AI, AlphaProof, astonished mathematicians with its stellar performance in the International Mathematics Olympiad, a high-level competition for students. “Superhuman intelligence is not just confined to games; it extends into crucial scientific endeavors,” Kohli emphasized.
The methodologies behind AlphaGo and large-scale language models like ChatGPT share similarities. The first phase, known as pre-training, feeds vast amounts of data into the neural network—either complete Go matches or the entirety of Internet content for language models. The second phase, post-training, refines the network using reinforcement learning, helping AI understand and achieve success.
For AlphaGo, this entailed self-playing millions of games to discover optimal strategies. AlphaFold relied on understanding correctly folded proteins. ChatGPT utilizes a process called reinforcement learning from human feedback to inform the model on preferable answers, guiding it through specific tasks like mathematics or coding.
However, this process isn’t without challenges. Neural networks often function as black boxes; their internal mechanisms can be too complex to comprehend fully.
During AlphaGo’s remarkable 37 moves, spectators initially believed the AI had made an error, only to later see its brilliance unfold as a strategic move. Yet, engineers at Google DeepMind could not elucidate why AlphaGo made that choice, leaving room for doubt about its reasoning.
“These models produce answers, yet we cannot discern whether they are profound insights or mere hallucinations,” Kohli commented. “We are actively exploring methods to address such issues.”
A large part of AlphaGo’s success stemmed from the quality of data utilized and having clear success metrics. This reinforces that AI thrives in fields where both conditions are met. Madison asserts that domains like mathematics and programming lend themselves well to easily defined success criteria. “These similarities highlight essential factors that drive progress in AI development,” he concluded.
In March 2016, Google DeepMind’s revolutionary artificial intelligence, AlphaGo, captivated the global audience by defeating world champion Lee Sedol in a historic five-game match of Go, an ancient Chinese board game. This milestone was viewed by millions, marking a pivotal advancement in AI technology.
Chris Madison, now a distinguished professor at the University of Toronto, played a critical role in AlphaGo’s creation while he was a master’s student. His journey began with a call from Ilya Sutskever, who later co-founded OpenAI.
Alex Wilkins: What inspired the AlphaGo project?
Elijah: Chris Madison and Ilya presented compelling arguments on why Go was a suitable challenge for AI, stating, “Do you think a skilled player can analyze a Go board and determine the optimal move in half a second?” This notion suggested the possibility of training neural networks to develop effective strategies for selecting the best moves.
Half a second reflects the rapid processing time of the visual cortex—a crucial insight from our previous work with ImageNET, an influential AI image-recognition competition.
Embracing this challenge, I joined the Google Brain team as an intern in summer 2014.
How did AlphaGo evolve from its inception?
Upon joining, I collaborated with a dedicated team at DeepMind, including Aja Huang and David Silver, who were already focused on Go. My primary task was to build the neural network, which felt like a dream come true.
We experimented with various approaches; many initial methods failed, leading to frustration. Eventually, I resorted to a straightforward strategy—training the network on a vast dataset of expert Go games to predict the next best move. This approach proved successful, laying the foundation for our project.
By the end of summer, we conducted a test match where my network outperformed DeepMind’s Thore Graepel, a competent Go player. This success sparked greater interest and investment in the project, allowing us to expand our team significantly.
How daunting was the challenge of defeating Lee Sedol?
I vividly recall the pressure of summer 2014, with a photo of Lee Sedol visible nearby. While I lacked Go expertise, my confidence grew with each network iteration. However, Aja kept reminding me, “Chris, Lee Sedol is an extraordinary player.”
Why did you depart from the AlphaGo team before the match?
David Silver expressed a desire for me to remain and further elevate the project, but I chose to focus on completing my PhD instead. I continued to advise on the project intermittently and take pride in my contributions, even though it took significant collaboration to create the version that ultimately faced Lee Sedol.
What was the atmosphere like during AlphaGo’s victory in Seoul?
The experience in Seoul during the match was indescribable—intense, emotional, and nerve-wracking. It felt reminiscent of a high-stakes sports event, where the outcome was uncertain despite our statistical advantage. From my hotel window, I witnessed crowds transfixed on giant screens showing our game, underscoring the massive impact this event had on East Asia.
What significance does AlphaGo hold for AI?
Though large-scale language models (LLMs) differ greatly from AlphaGo, the underlying technical principles remain unchanged. Initially, neural networks are trained to predict subsequent moves; similarly, today’s LLMs utilize pre-training to forecast the next word using vast amounts of text data.
AlphaGo’s advancement came from integrating human input into the neural network and refining its strategies through reinforcement learning—all focused on the objective of winning games.
As with LLMs, post-preparation reinforcement learning is essential for aligning networks with our intended applications.
In many aspects, the foundational principles of AI development remain consistent.
What areas in AI do you see as flourishing?
Our progress hinges on the availability of comprehensive data for training and reinforcement signals. Without these critical components, no algorithm, no matter how expertly designed, can make meaningful advances.
Did you empathize with Lee Sedol?
Throughout the summer of 2014, Lee Sedol became an idol, making the stakes incredibly high during the match. The immense pressure he faced was palpable, and while watching him realize the gravity of the competition, my heart went out to him. After losing, he apologized, claiming, “This is my failure, not yours,” which was truly heartbreaking.
In Go, players typically review matches to reflect on their performance. Lee Sedol couldn’t do that with AlphaGo and instead sought a friend for analysis, yet it lacked the same reflective quality. Despite the narrative often framing the match as human vs. machine, it was important to recognize the collaboration behind creating AlphaGo, showcasing the dedication of everyone involved in developing this groundbreaking technology.
As AI takes on more human-like tasks, is there still a role for humans?
The game of Go, which we find beautiful, can still teach us more through AI’s insights. The ultimate goal of Go may be to win, but it is also about enjoyment. Thus, the advent of AI doesn’t diminish board games; industries like chess continue to thrive with human appreciation.
There is a concerning issue with the “Higgs field”, the pivotal energy field responsible for giving particles mass. Recent studies indicate it may be dangerously close to becoming inherently unstable. In the absence of particles, the Higgs field exhibits a non-zero background “vacuum energy.”
However, scientists suggest that this could merely represent a “trough” of energy, rather than the absolute minimum energy of the Higgs field.
An analogy for this scenario is a ball rolling down a hill, getting stuck in a crater. The ball remains stable in the crater, yet it hasn’t reached the lowest energy point possible.
Physicists describe this condition as a “metastable” state, with the resulting background energy referred to as a “false vacuum.” Current measurements indicate we exist in a universe characterized by this false vacuum.
But what if the Higgs field unexpectedly transitioned to a lower energy state? Such an event, termed a “vacuum collapse,” could spell disaster for our universe. The constants of nature would alter, resulting in a completely different realm of physics, chemistry, and biology.
This event could annihilate and recreate the universe in a massive release of energy, the nature of the new universe remains unknown.

How probable is this scenario? For a vacuum collapse to happen, a significant concentration of energy in a minuscule volume is required. Yet calculations reveal no known process can achieve this.
Nonetheless, the Higgs field adheres to the principles of quantum physics. There exists a phenomenon called “tunneling” that permits the Higgs field to spontaneously shift to another energy state, akin to our ball piercing the ground and escaping the crater.
Fortunately, calculations indicate this occurrence is exceedingly rare, estimated at about once in 10100 years (1 followed by 100 zeros). However, just because an event is unlikely doesn’t mean it is impossible.
In fact, vacuum collapse might have already commenced somewhere in the universe, racing through space at the speed of light. This catastrophic event would obliterate everything in its path, with no warning before it arrives. But there’s no need to panic.
This article addresses a question posed by Kirill Jerdev via email: “Is it possible for the universe to explode?”
Paleontologists have discovered a new giant species of Mosasaurus, named Pluridence Imeraki, derived from Late Cretaceous phosphate deposits in Morocco. This slender-jawed mosasaur may have reached over 9 m (29.5 ft) in length, making it a significant addition to the mosasaur family.
Pluridence Imeraki holotype, enlarged view of the tooth. Scale bar – 10 cm. Image credit: Nicholas R. Longrich & Nour-Eddine Jalil, doi: 10.3390/d18030159.
Pluridence Imeraki existed in the ocean during the late Maastrichtian period of the Cretaceous, roughly 66 to 67 million years ago.
This species is classified under the Halisauridae subfamily, which typically includes smaller mosasaurs. Early members ranged from approximately 4 to 5 m (13 to 16.4 ft) long, such as Halisaurus, which could grow up to about 7.5 m (24.6 ft) in closely related species like Pluridence Serpentis.
At over 9 meters long, Pluridence Imeraki rivals the largest predatory mosasaurs from the region.
Dr. Nicholas Longrich from the University of Bath and Dr. Nour Eddin Jalil from the National Museum of Natural History in Paris remarked, “The Late Cretaceous saw a significant expansion of mosasaurs, a specialized group of large marine predators that dominated the oceans during the final 25 million years of this period in Marrakech.”
“Morocco’s late Maastrichtian Phosphate Formation is home to the most diverse mosasaur assemblage known, featuring what could be the richest marine reptilian fauna globally.”
“In recent years, numerous new mosasaur species have been identified, with over 16 species reported so far.”
“The four primary subfamilies of mosasauridae represented in these phosphates include mosasauridae, plioplatecarpini, tylosauridae, and halisauridae, along with basal mosasauridae like Pachybalanus.”
“While mosasaurids account for most of the species diversity, halisaurids thrived in phosphate-rich areas and were prevalent across Africa during the Cretaceous.”
Relative sizes of Pluridence Imeraki, Pluridence Serpentis, and Halisaurus aramburgi, all extracted from Morocco’s latest Maastrichtian phosphates. Scale bar – 1 m. Image credit: Nicholas R. Longrich & Nour-Eddine Jalil, doi: 10.3390/d18030159.
A 1.25 m (4.1 ft) long skull, along with the lower jaw of Pluridence Imeraki, was unearthed from the phosphate layer of Couche III in Sidi Chennan, Kouribga department, Morocco.
The phosphate layer represents a marine upwelling zone, deposited in a shallow marine embayment along the eastern edge of the Atlantic Ocean from late Maastrichtian to early Eocene times,” noted the paleontologist.
“These formations are part of vast phosphate accumulations that arose along the Tethyan Mountains and the eastern Atlantic margin during the Late Cretaceous and early Paleogene.”
Compared to related species, Pluridence Imeraki likely exhibited a distinct feeding strategy.
Variations in jaw structure, tooth shape, and eye size suggest that this species occupied unique ecological niches in the marine ecosystem at the Cretaceous’s end.
“We discovered that halisaurids were not only more diverse than previously imagined, but also exhibited greater variation in tooth morphology, jaw shape, and body size,” the researchers concluded.
“Instead of merely competing with mosasaurines, halisaurinae experienced a minor adaptive radiation during the Late Cretaceous and served as significant components of low-latitude ecosystems.”
The discovery of Pluridence Imeraki was detailed in a research paper published in this week’s edition of Diversity.

The ongoing northward shift of the Gulf Stream indicates a concerning trend: the weakening of the ocean current system crucial for keeping Europe warm. Recent models suggest that unexpected changes in the Gulf Stream may signal an imminent catastrophic collapse of this vital current.
The Atlantic Meridional Circulation (AMOC) is a flow of warm, salty surface water originating in the tropics, moving towards northwest Europe, where it cools, sinks, and returns south along the ocean floor. Specifically, the Gulf Stream is the component that travels from the Gulf of Mexico up the East Coast of the United States, redirecting eastward into the Atlantic Ocean.
As the Greenland ice sheet continues to melt, it releases fresh water into the North Atlantic. This dilution is expected to hinder AMOC’s strength, as the less salty water affects the sinking and southern flow of this essential current. While some studies indicate this phenomenon is already in effect, clear evidence remains elusive.
Recent research led by René van Westen and Henk Dykstra, both affiliated with Utrecht University in the Netherlands, reveals that the weakening of AMOC is altering the Gulf Stream’s path, causing it to shift further north along the U.S. coastline before veering back into the Atlantic Ocean.
The findings demonstrate that the Gulf Stream has already shifted approximately 50 kilometers north over the past 30 years, as indicated by satellite data.
“This shift is measurable,” Van Westen stated. “As a result, it is very likely indicative of AMOC’s weakening.”
Historical reconstructions that estimate the AMOC discharge based on ocean temperatures indicate a 15 percent reduction since 1950. However, monitoring of actual ocean flows began only in 2004, insufficient to determine if the observed changes are natural variations or accelerating trends.
“We’re exploring alternative methods, such as analyzing the Gulf Stream’s pathway,” Van Westen remarked.
The study employs a model with 10-kilometer resolution, rather than the standard 100-kilometer resolution, facilitating the examination of the bulge responsible for the significant volume of water transported by the Gulf Stream.
The trajectory of this bulge varies as one of AMOC’s tributaries, the Deep Western Boundary Current, transports cold saline water southward along the ocean floor. Typically, this current flows below the Gulf Stream, exerting a pull that moves the Gulf Stream southward. However, as AMOC weakens, the Deep Western Boundary Current diminishes as well, leading to a gradual northward shift of the Gulf Stream.
In simulation scenarios extending 392 years into the future, the Gulf Stream is projected to leap more than 200 kilometers northward in a mere two years, followed by the collapse of AMOC two and a half decades later. Previous studies indicate that such a collapse could lead to severe climate consequences, such as a -20°C (-4°F) cold wave in London and an extreme -48°C (-54°F) temperature in Oslo, Norway.
This modeling represents an idealized scenario and does not predict that AMOC will collapse in 400 years. Nevertheless, it does highlight that a rapid shift in the Gulf Stream could serve as an early warning for an impending AMOC closure—a unique early indicator available to us. By that point, it may be too late to averting AMOC collapse, but proactive measures, such as enhancing home insulation and exploring agricultural areas further south, could be taken by Europe.
“We now possess effective early warning indicators that can be quantified,” Van Westen asserts. “This is straightforward to measure.”
Nonetheless, the timeline for AMOC’s potential collapse following Gulf Stream changes remains uncertain. Predictions for AMOC closure vary significantly, ranging from decades to centuries.
Dan Seidoff, a retired oceanographer with the National Oceanic and Atmospheric Administration, cautioned that fresh water from Greenland could impact AMOC at a rate and location different from model predictions.
“Critical questions remain about when, how, and why AMOC changes might occur,” he explained. “If changes follow the model’s predictions, it could serve as a precursor indicating Gulf Stream shifts and issue warning signals.”
While the correlation between abrupt changes and AMOC collapse must be validated by additional models, this study strengthens the case that AMOC is indeed experiencing a slowdown, according to Stefan Rahmstorf of the University of Potsdam, Germany.
“The slowdown seems to be happening at a pace faster than predicted in global warming scenarios,” he noted. “Current climate models may not adequately capture the urgency of this issue, potentially altering estimations regarding when the AMOC tipping point will occur.”

For the first time in history, humanity successfully altered the orbit of an asteroid around the sun. This groundbreaking achievement was made possible by NASA’s Double Asteroid Redirection Test (DART) mission conducted in 2022, with its effectiveness now being assessed.
DART targeted a small asteroid named Dimorphos, which orbits a larger asteroid called Didymos. The spacecraft was designed to collide with Dimorphos to test the kinetic impactor method, exploring whether this technique is a viable way to change an asteroid’s trajectory, particularly if one were to threaten Earth.
The mission proved to be a resounding success, reducing Dimorphos’ orbital period by 32 minutes. Astronomers have been monitoring the asteroid system closely since then, collecting approximately 6,000 observations. These efforts revealed a slowdown of about 11.7 micrometers per second in the overall orbit, equivalent to approximately 40 millimeters per hour. This change is projected to reduce the orbital radius by around 360 meters.
“While it may not sound significant, the concept of dynamic effects suggests that early impacts can lead to substantial changes over time,” says Rahil Makadia of the University of Illinois at Urbana-Champaign, a member of the asteroid monitoring team. “Though this number seems small, its accumulation over decades can have a considerable impact.”
The observed slowdown resulted from two main factors: the initial impact of the spacecraft and a secondary thrust caused by debris ejected from Dimorphos’ surface. Makadia and his colleagues determined that these two effects were roughly equivalent, allowing for accurate calculations of the asteroid’s mass and density. Dimorphos is approximately half as dense as Didymos, supporting the hypothesis that it is a rubble pile formed from material ejected during Didymos’s rotation.
This groundbreaking data can be invaluable in future efforts to redirect potentially hazardous asteroids. “We now possess a solid foundation for predicting the outcomes of future dynamic collision missions,” states Makadia. Additionally, the European Space Agency’s Hera spacecraft, en route to Didymos and scheduled to arrive in November, is expected to provide even more precise measurements, enhancing our ability to safeguard Earth from incoming asteroid threats.
Unforeseen vaccine side effects: Staying sharp is a bonus!

Recent studies indicate that chronic inflammation in various body areas could contribute to Alzheimer’s disease. While it may take time to fully understand these connections, it’s evident that persistent inflammation has adverse effects and that reducing it can provide numerous health benefits.
Inflammation is the body’s response when immune activity exceeds normal levels, such as when a wound becomes infected. While short-term inflammation is beneficial, prolonged inflammation can lead to serious health issues, including cancer, heart disease, stroke, rheumatoid arthritis, and mental health disorders like depression and anxiety.
To combat long-term inflammation and enhance both physical and mental health, consider the following tips:
1. Get Vaccinated
Vaccines, including those for shingles, tuberculosis, and influenza, have demonstrated a reduced risk of dementia. For instance, individuals who received the Shingrix vaccine experienced a 17% lower chance of developing dementia compared to those who had the older Zostavax vaccine, which also lowers dementia risk. Though the exact mechanism remains unclear, vaccines likely reduce inflammation.
2. Maintain Good Oral Hygiene
Gum disease is another inflammatory condition linked to an increased risk of Alzheimer’s and heart disease. Bleeding gums can allow harmful bacteria to enter the bloodstream, which is why good dental hygiene is essential for preventing periodontal disease and maintaining overall health.
3. Embrace a Mediterranean Diet
A Mediterranean diet is rich in anti-inflammatory foods such as fruits, beans, nuts, whole grains, fish, and olive oil, while minimizing inflammatory foods like red and processed meats. This dietary approach not only helps in reducing inflammation but is also associated with longevity and overall wellness.
4. Exercise Regularly
Sedentary lifestyles contribute to increased inflammation. Numerous studies suggest that regular exercise diminishes inflammation. Whether it’s vigorous workouts or gentler activities like yoga, incorporating movement into your routine can provide significant health benefits.
5. Achieve a Healthy Weight
Although the connection is still being explored, obesity is often linked to ongoing inflammation. It raises an interesting question: Could medications like GLP-1, often used for weight loss, reduce Alzheimer’s risk? Current evidence shows that those using GLP-1 medications may experience lower dementia risk, but results for those without diabetes are still unclear.

A revolutionary method for detecting chemical properties of living organisms could unlock the secrets to identifying extraterrestrial life forms, even those with biochemical processes distinct from life on Earth.
In the quest for extraterrestrial life, scientists traditionally depend on biosignatures—substances or patterns that reliably signify the presence of life. By analyzing the atmospheres of distant planets, astronomers search for molecular biosignatures. However, many molecules associated with life can also arise from geological activities, suggesting a careful approach to interpretation.
A novel test developed by Christopher Carr and colleagues from Georgia Tech focuses on amino acids, which serve as fundamental components of proteins that sustain all known life forms. While amino acids can also be produced in lifeless environments, they have been uncovered in lunar soil, comets, and meteorites.
Given this, Carr and his team proposed that analyzing the reactivity of molecules within samples could provide more reliable biological indicators than merely detecting amino acids.
In non-living systems, molecules are continuously formed and destroyed as they react with environmental factors like cosmic rays. The more reactive a molecule, the more likely it is to decompose. “Without stable systems to maintain molecules, their reactivity increases,” explains Carr. However, living systems require reactive molecules, therefore they retain more reactive ones, creating distinct biochemical signatures.
The reactivity of compounds hinges on the arrangement of electrons in the molecules. More reactive molecules exhibit smaller energy differences between their outermost electron and the next available electron space during reactions.
Carr and his team calculated energy differences for 64 amino acids, including those not present in Earth’s biosphere. They analyzed the prevalence of these amino acids in samples sourced from both abiotic processes (like meteorites and lunar soil) and biotic sources (like fungi and bacteria), employing molecular energy calculations to establish a statistical framework for amino acid reactivity. This allowed them to estimate the probability of a sample being alive or inorganic.
After testing over 200 living and nonliving samples, they found their method could accurately identify life with 95 percent certainty. “This approach is remarkably straightforward,” Carr asserts. “It’s easily explainable and directly linked to the principles of physics.”
This reactivity-based method is applicable to the search for extraterrestrial life, as Carr posits that if life exists elsewhere, it likely relies on carbon-based chemistry and amino acids, governed by the same principles of chemical reactivity present on Earth. “Life inherently requires control over the timing, methods, and locations of molecular interactions. Therefore, structures that facilitate electron flow and molecular interactions are essential,” Carr notes.
While utilizing molecular reactivity to identify life isn’t new, measuring reactivity through statistical distributions is an innovative advancement. Henderson Cleaves from Howard University suggests that this method could enhance the toolkit of life-detection instruments on forthcoming space missions to Mars or the moons of Saturn, most notably Enceladus. However, Cleaves notes that the technology to accurately measure molecular abundance is a significant challenge.

Two remarkable species of marsupials, long considered extinct and previously known only from fossil records, have been rediscovered alive in New Guinea. This groundbreaking finding is the result of a collaborative effort involving scientists, indigenous communities, and citizen scientists.
The confirmation of the pygmy longfinger possum and the ring-tailed glider as living specimens marks a significant moment—it’s the first time these creatures have been seen in over 7,000 years. The announcement was made by Bishop Museum, based in Honolulu.
“As both a scientist and conservationist, it’s incredibly fulfilling to confirm their existence. This opens a new chapter in our journey to learn about and protect these fascinating animals,” stated Dr. Christopher Helgen from Bishop Museum.
For the past two years, Helgen and Dr. Tim Flannery of the Australian Museum have been dedicated to verifying the existence of these elusive mammals.
These two animals are categorized as “Lazarus species,” a term for species that re-emerge after being presumed extinct. “The discovery of two Lazarus species thought to be extinct for millennia is truly unprecedented,” Flannery noted in a press release.
Helgen believes this rediscovery underscores the idea that “extinction is avoidable.”
“This discovery offers a message of hope and a testament to second chances,” he added.
These species were initially discovered through fossils by Dr. Ken Aplin, who unearthed a critical tooth during an archaeological dig in western New Guinea in the 1990s.
Helgen’s observation of a photo featuring a gliding ring-tailed possum led to the identification of it as one of Aplin’s previously “extinct” species. Indigenous communities from West Papua’s Tambulo and Maybrat regions provided invaluable assistance by sharing their extensive knowledge about the marsupial’s unique lifestyle, according to a press release.
Recently, scientists confirmed the existence of the pygmy longfinger possum after discovering two preserved specimens at the University of Papua New Guinea.
The survival of the pygmy longfinger possum has been further validated by citizen scientists. Carlos Bokos, a citizen scientist and now co-author of the study, shared a photo of the species on iNaturalist, a global platform for documenting natural science discoveries.

Global warming is accelerating at an alarming rate, occurring at twice the speed compared to previous decades. This increase indicates that significant climate changes could emerge sooner than anticipated.
From 2013 to 2014, the Earth warmed by approximately 0.18°C per decade. This trend has since escalated, with a temperature rise of roughly 0.36°C per decade noted in recent analyses by Stefan Rahmstorf and his team at the University of Potsdam, Germany.
If the current rate of global warming persists, humanity risks violating the Paris Agreement’s cap of limiting global temperature rise to 1.5°C by as early as 2028—much sooner than various forecasts suggest.
“Every fraction of a degree is crucial, amplifying the consequences of global warming manifesting as severe weather events and ecological disturbances,” Rahmstorf states. “With the notable exception of the United States, the global community aims to mitigate and curb the effects of climate change. The current trajectory suggests a worrying acceleration in warming trends.”
After experiencing unprecedented heat levels, climate scientists are actively discussing the potential for further acceleration in global warming throughout 2023. However, natural phenomena like El Niño have complicated efforts to ascertain whether the observed temperature rises are attributable to climate change or merely transient weather patterns.
Rahmstorf’s research is pioneering, revealing a statistically significant acceleration in global warming attributable to climate change, with 98% confidence.
This collaborative research assessed five distinct global temperature datasets, some indicating even higher temperature spikes. Based on a 20-year average, global warming may be 1.5°C hotter this year compared to pre-industrial levels, as suggested by data from the European Center for Medium-Range Forecasts.
Warm-water coral reefs are on the brink of collapse, and exceeding the 1.5°C threshold risks triggering further tipping points, including irreversible glacial melting in Greenland and West Antarctica, as well as deforestation in the Amazon rainforest.
Many scientists contend that the recent acceleration in global warming primarily results from the restrictions imposed on sulfur dioxide emissions from shipping in 2020. While harmful to public health, this pollutant previously formed an aerosol mist, shielding the Earth from excess sunlight and cooling the atmosphere.
With this sunlight barrier now diminished, the rate of warming might decelerate, though unconfirmable at this stage, notes Rahmstorf. The ongoing shift from fossil fuels is likely to decrease air contaminants that have masked temperature rises.
Aerosol levels will continue to decline, but swift adjustments in shipping emissions are improbable. “A gradual easing in warming rates over the next decade is plausible,” he adds.
Alongside the effects of El Niño, researchers also considered volcanic eruptions that generate haze obstructing sunlight, as well as heightened solar radiation during sunspot peaks. After disregarding these impacts, they applied two distinct models to global temperature data. Both indicated a marked acceleration in warming, albeit at different intervals.
Nevertheless, the study’s authors caution that completely isolating the temperature influences of El Niño, eruptions, and sunspots remains a challenge, as stated by Zeke Hausfather from Berkeley Earth, California. This raises the possibility of a slight overestimation in the acceleration of global warming. Nonetheless, the evidence strongly supports the notion of a quicker pace of change, he asserts.
“The key take-home message is that while exact figures on the acceleration rate of warming are still pending, there is compelling evidence suggesting it is intensifying,” Hausfather concludes. “We must await additional data over the next few years for clearer insights.”
Imagine showing someone a box and asking them to guess its contents without any hints. This might seem impossible, yet the box’s nature offers crucial clues. For instance, its size implies the contents are smaller, and the material — metal versus cardboard — hints at what it can hold.
Is there a mathematical way to explain how to make educated guesses based on limited information? Indeed, while outcomes like coin flips or dice rolls are random and unpredictable, many scenarios allow us to optimize our guessing strategies using a few clever tools.
These constrained guesses are essentially estimates, a concept with deep historical roots. A remarkable early example comes from the ancient Greek philosopher Eratosthenes, who resided in Alexandria, Egypt, during the third century BC. Using basic principles, he estimated Earth’s circumference with astonishing accuracy. Though his precise method has been lost, subsequent writings enable us to reconstruct it.
Eratosthenes observed that during noon on the summer solstice, the sun was directly overhead in Syene, causing no shadow in the city’s well. Meanwhile, in Alexandria, a vertical pole cast a shadow of about 7 degrees, or approximately 1/50th of a circle. Knowing the distance between the two cities was 5000 stadia, he estimated Earth’s circumference to be 250,000 stadia.
While Eratosthenes made geometric approximations that can be overlooked, the real challenge lies in determining the length of a stadion — estimated to be around 160 meters. This approximation yields a circumference of approximately 40,000 kilometers, quite close to the modern measurement of 40,075 kilometers. Variations in stadion measurements, ranging from 150 to 210 meters, affect precision, depending on how we interpret Eratosthenes’ work.
Estimating Earth’s Circumference
Chronicle/Alamy
The key takeaway is that with simple yet logical calculations, we can deduce significant insights — all without a globe in hand. In the 20th century, physicist Enrico Fermi exemplified this art of estimation, playing a pivotal role in the Manhattan Project which led to the development of the atomic bomb. During the Trinity test, he ingeniously gauged the explosion’s power by dropping small pieces of paper and observing their movements. Though the specifics of his technique remain elusive, his initial estimate of a 10 kiloton bomb was intriguingly close to the accepted yield of 21 kilotons.
Fermi’s knack for educated guesses gave rise to the concept known as the “Fermi problem.” One classic illustration involves estimating the number of piano tuners in Chicago. Starting with a population of around 3 million, estimating the number of households and pianos leads to a rough conclusion of about 150 piano tuners based on several reasonable assumptions.
The crux of this estimation lies in understanding the limits of its imprecision. While we’ve made numerous assumptions during the process, the errors are likely to balance out. An estimate suggesting a million piano tuners would be almost certainly incorrect.
Fermi estimation serves as a valuable tool for generating initial hypotheses, but as we obtain more information, we can refine our guesses. Returning to the box analogy, if a blue ball with the number 32 is drawn from it, our assumption about the contents shifts. Acknowledging that multiple colored balls are likely, we can utilize the statistics pioneered by Thomas Bayes in the 18th century to quantify this uncertainty.
Portrait of Thomas Bayes

Bayes revolutionized probability by transforming it from a method for understanding randomness into a framework for addressing uncertainty. His Bayes’ theorem offers a way to quantify observations into evidence, comprised of four components: ex ante, evidence, likelihood, and ex post.
Prior values denote fundamental assumptions. Imagine serving three ice cream flavors (chocolate, strawberry, and vanilla) at a gathering. Initially, you might assume each flavor will be equally popular. However, if the first ten guests all choose chocolate, your initial assumption may need reevaluation.
Evaluating the likelihood of ten consecutive chocolate selections under equal preference assumptions reveals a probability of approximately 1 in 60,000—a strong indicator to revise your original beliefs. Such updates provide a more accurate understanding moving forward.
This theorem proves powerful. Referring back to the box example, drawing a colored ball like red ’50’ sharpens the possibilities of what remains inside. Each draw further narrows down our options based on new evidence.
One practical use of Bayes’ theorem appears in spam filters. Early versions used Bayesian inference to categorize a certain percentage of emails as spam (ex ante) and learned to recognize spam emails by examining user-marked emails (evidence) and the likelihood of certain words’ presence in those emails (likely).
This application illustrates how estimation matters in real-world scenarios, far beyond mere mathematics. Especially with modern AI technologies like ChatGPT, understanding and applying Fermi estimation and Bayesian inference techniques is increasingly vital. As observed, AI often seeks to confirm pre-existing information, thus neglecting new data for accurate assessments. Equip yourself with the skills to make informed guesses.
Imagine launching from Earth on a clear day; the sky transforms from a bright blue to the deep black of outer space as you ascend. This transition, from vivid blue to the engulfing void, reveals an optical phenomenon caused by sunlight interacting with our atmosphere.
Despite our understanding today of this optical effect, the perception of space at the time was quite different. While Yuri Gagarin is celebrated as the first human in space, the question remains: was he truly the first to experience the vastness of outer space?
To explore this, we must consider the definitions of where the universe commences. The International Aeronautical Federation designates the Kármán Line at 100 kilometers above Earth, while the U.S. government sets it at 80 kilometers (50 miles). Yet these definitions are arbitrary, often tailored to align with specific technological capabilities and aerial standards.
According to the Oxford English Dictionary, space is defined as the “physical universe… beyond the Earth’s atmosphere.” Interestingly, scientific understanding of our atmosphere’s extent has evolved, suggesting it extends even beyond 630,000 kilometers. Future NASA missions, like Artemis II, are set to venture beyond the Moon, yet they will still fall short of the more than 200,000 kilometers to reach the ultimate boundaries of space.
While it seems absurd to claim that Apollo astronauts didn’t reach space, we still seek deeper definitions based on historical and cultural perspectives. What truly exemplifies the essence of “space”?
Witnessing the Sky Disappear
One significant boundary marks the moment the atmosphere no longer refracts sunlight, revealing the stark blackness of space. Historically, many Europeans believed in a bright, blue universe, a misconception maintained until scientists corrected it in the 17th century. The first astronauts to witness this darkness shattered centuries of misunderstanding.
In the 1930s, high-altitude balloonists pushed the envelope. In 1935, the U.S. Explorer II, piloted by Albert Stevens and Orville Anderson, soared to 22.1 kilometers, where they experienced an atmospheric shift. Their descriptions of the horizon hinted at the transition Gagarin would later confirm. Nonetheless, they witnessed a “very deep blue” sky rather than a true black.
In 1956, Malcolm Ross and Lee Lewis ascended to 23.2 kilometers in their Stratolab I balloon, noting the sky appeared black, a milestone in the pursuit of understanding space. This insight continued with David Simmons in the Mann High II balloon, who at 22.9 kilometers witnessed a similarly dark sky.
While rocket-powered aircraft approached these altitudes, they lacked the prolonged visibility balloonists had. In 1951, William Bridgman reached 24.2 kilometers but could barely observe the sky due to the brevity of his flight. Conversely, in 1956, Iven Kincheloe flew higher in the Bell X-2, reporting once again on the intriguing color transformations of the sky.
Confronting the Hostile Sky
Over time, the insight balloonists gained about the transitions from blue to black became crucial. David Simmons, during his 1957 flight, marveled at the hazy horizon blending with the vast blackness of space. To him, the enclosed gondola was akin to a spacecraft floating amid the void.
Joseph Kittinger’s iconic 1960 parachute jump from 31.3 kilometers illustrated the black, uninviting expanse above. He notably remarked on the hostility of the sky above him, acknowledging the inherent challenges of conquering space—conclusions echoed by Gagarin years later.
Not all spaceflights occur during daylight, yet witnessing the transition from blue to black remains pivotal for astronauts. In 2021, actor William Shatner’s experience aboard Blue Origin reached 107 kilometers. He encapsulated the moment: “It’s fascinating to see blue color passing by you, then immediately facing blackness.”
While the Kármán line exists as a conceptual framework, the emotional impact of seeing the sky fade remains profound. Those early visionaries, witnessing this transition, forever altered our understanding of what it means to reach space, a claim equally valid for their experiences as it is for Gagarin’s historic flight.
A dust plume from the Sahara Desert is set to arrive in the UK this week, potentially creating stunning sunrises and sunsets as well as what is known as “blood rain.”
Fine dust and sand particles, lifted thousands of miles by winds from North Africa, will contribute to a unique atmospheric phenomenon.
According to the Japan Meteorological Agency, “Dust in the air is expected to continue moving across the UK today and into tomorrow. This could lead to hazy skies and, in some cases, a build-up of dust on surfaces such as cars, especially if showers occur.”
During sunrise and sunset, this dust can turn the sky into deep shades of gold and orange.
“Dust particles are highly efficient at scattering sunlight, significantly contributing to the stunning red hues of sunsets,” says Dr. Claire Ryder, an Associate Professor of Mineral Dust Processing at the University of Reading.
“The iron oxides in the dust absorb blue light, further enhancing the red color in the sky.”
These iron oxides can even lead to blood rain, although the sight may not be as dramatic as it sounds.
“Despite the ominous name, this is a simple phenomenon,” explained Ryder. “When rain falls through dust-laden air from the Sahara, it picks up tiny reddish-brown particles, leaving rusty-orange stains on cars, windows, and garden furniture.”
“This explains why your car may appear slightly muddy after the rain showers this week.”
Typically, dust-laden rain in the UK is present in such low concentrations that the droplets appear normal to the naked eye.
You might want to delay that car wash until the weekend to avoid needing multiple cleanings!

This Saharan dust not only affects your car but can also impact air quality, increasing particulate matter, or pollution, in the atmosphere.
With pleasant spring weather, weak winds in the south and east of the UK may cause dust to linger and accumulate in certain areas.
Fortunately, the Japan Meteorological Agency assures that there are no significant health concerns, though individuals with pre-existing respiratory conditions might experience slight air quality degradation.
While it may seem surprising, it’s not uncommon for Saharan dust to find its way to the UK. When sandstorms in North Africa interact with specific wind patterns, sand travels northwards.
Mr. Ryder noted, “Over the next few days, southerly winds ahead of an advancing front will push the dust plume across the UK. Current forecasts suggest that this dust could linger into Sunday night.”
A groundbreaking discovery of a 90-million-year-old fossil in Argentina is reshaping our understanding of the evolutionary history of a unique group of bird-like dinosaurs. This find helps settle a longstanding debate regarding their distribution across the ancient world.
The fossils detailed in Nature belong to Arunachetri seropolisiensis, a member of the Alvarezaurus family. This small dinosaur is characterized by its tiny teeth and stout arms, which end in a prominent single thumb claw.
While most well-preserved Alvarezsaurus fossils have been discovered in Asia, the existence of Alvarezsaurus in South America raises intriguing questions due to the vast ocean separating these continents.
A nearly complete skeleton uncovered at the La Buitrera fossil site in northern Patagonia has provided remarkable evidence regarding this species. This region was also home to primitive snakes and small saber-toothed mammals.
“Creating a nearly complete, articulated animal from a fragmented skeleton is akin to discovering the Rosetta Stone of paleontology,” stated Peter Makowiecki, a professor at the University of Minnesota, and the study’s first author.
Unlike their later relatives, Arunashetri had longer arms and larger teeth. This indicates that Alvarezsaurids likely reduced their body size before evolving the characteristic small limbs and teeth suited for an ant and termite diet.
“Our study suggests that alvarezsaurids form a compact group of dinosaurs, with species sizes ranging from crows to humans,” Makowiecki told BBC Science Focus. “Body size appears to fluctuate within this limited range without a clear trend.”

This discovery also addresses an intercontinental mystery. A detailed anatomical study of Arunashetri led Makowiecki and his team to examine fossil collections globally. “We found other Alvarezaurids hiding in plain sight,” he noted.
“These species, which existed during the Jurassic period in North America and the Early Cretaceous in Europe, enhance our understanding of Alvarezsaurus’s widespread presence prior to the major rift between the Northern and Southern Hemispheres.”
Approximately 200 million years ago, all of Earth’s continents formed a single supercontinent named Pangea. This landmass gradually fragmented over tens of millions of years, evolving into its current configuration while transporting its fauna along with it.
The research team is preparing additional specimens from the same site, though Professor Makowiecki has remained tight-lipped about their specifics. “The new specimen confirms some of our findings regarding size and specialization,” he disclosed. “Currently, we have no further plans.”

Astronomers have utilized spectral data from the Hobby-Eberly Telescope at McDonald Observatory to construct the most intricate 3D map of faint cosmic structures dating back 9 to 11 billion years, unveiling galaxies and intergalactic gas previously undetectable by telescopes.

“Studying the early Universe reveals how galaxies have evolved into their current forms and the role that intergalactic gas plays in this transformation,” stated Dr. Maya Lujan Niemeyer, an astronomer at the Max Planck Institute for Astrophysics and Ludwig Maximilian University of Munich, and a key member of the Hobby-Eberly Telescope’s Dark Energy Experiment (HETDEX).
“Many objects from this epoch are faint and challenging to observe due to their vast distances,” she continued.
“Through a technique known as line intensity mapping, this innovative map enhances our understanding of these objects, adding complexity and depth to this crucial era of cosmic history.”
Although line intensity mapping is not a novel methodology, this is the first instance it has been employed to visualize Lyman alpha emissions with such exceptional precision across an extensive dataset.
The HETDEX project harnesses the capabilities of the Hobby-Eberly Telescope to catalog over 1 million luminous galaxies to decode the mysteries of dark energy.
What differentiates this project is its extensive measurement scope, equivalent to observing more than 2,000 full moons and amassing a colossal dataset of over 600 million spectra across an expansive area of the sky.
“We leverage only a fraction of our data—approximately 5%,” remarked Dr. Karl Gebhardt, principal investigator of HETDEX and an astronomer at the University of Texas at Austin.
“This leaves significant potential for future research utilizing the remaining data.”
“While HETDEX captures images of the entire sky, only a small subset of the collected data comprises sufficiently bright galaxies for our research,” noted Dr. Lujan Niemeyer.
“These galaxies are merely the beginning. In the vast expanses in between, lies an entire ocean of light awaiting discovery.”
To construct this groundbreaking map, astronomers employed a supercomputer at the Texas Advanced Computing Center to meticulously analyze approximately half a petabyte of HETDEX data.
Using the coordinates of luminous galaxies already detected by HETDEX, they inferred the positions of fainter galaxies and adjacent glowing gas.
Due to the gravitational forces that cause matter to cluster, the existence of one bright galaxy implies the presence of nearby celestial objects.
“This allows us to utilize known galaxy positions as reference points to ascertain distances to fainter celestial entities,” explained Dr. Eiichiro Komatsu, HETDEX scientist and astronomer at the Max Planck Institute for Astrophysics.
“The resultant map emphasizes regions surrounding bright galaxies while providing intricate details of the areas in between.”
“Simulation models exist for this cosmic era, yet they remain hypothetical; they do not represent the actual universe.”
“We now possess a foundational understanding that allows us to verify whether the astrophysics underlying these simulations holds true.”

A groundbreaking discovery of a 7.2-million-year-old femur at the Azmaka fossil site in southern Bulgaria reveals a unique blend of locomotor features, suggesting both quadrupedal and bipedal abilities. This significant finding involves a research team led by Professor Madeleine Böhme from the Senckenberg Center for Human Evolution and Paleoenvironment at the University of Tübingen. The fossil has been tentatively linked to Grecopithecus, a fossilized species of ape known from fragmented archaeological sites in the Balkans, which is considered by some as a contender for the earliest known human species.

Researchers regard Grecopithecus as a controversial late Miocene ape fossil, estimated to be around 7.2 million years old.
Some experts speculate that this ancient species could represent the earliest humans, potentially predating fossils traditionally linked to early human ancestry in Africa.
The fossil record of Grecopithecus includes a partial lower jaw discovered near Athens, Greece, in 1944, alongside isolated upper premolar fossils from Bulgaria examined in the 2010s.
“This ancestor from 7.2 million years ago is classified within the genus Grecopithecus and may represent the oldest known hominid,” stated David Bigan, a professor at the University of Toronto and co-author of the study.
The analysis in the study involved nearly complete femurs from Grecopithecus unearthed from the Azmaka site.
The newly discovered fossil, located in floodplain sediments dating back approximately 7.2 million years, showcases distinctive features. The Azmaka femur’s bulbous head is noticeably separated from the neck, with an elongated, diagonally ascending medial edge characteristic of hominids.
While this find does not fully represent the range of adaptations seen in later bipedal species, the angle of the neck axis falls within the lower spectrum observed in modern humans and approaches estimates for early human ancestors such as Orrorin, but remains below the typical angle found in suspensory apes like orangutans.
Researchers suggest that this combination of anatomical features indicates a transitional form of bipedalism that is neither specialized for climbing nor fully adapted for terrestrial life.
Weight estimates based on the dimensions of the femur suggest Grecopithecus weighed approximately 23-24 kg, akin to a small chimpanzee.
Professor Nikolai Spasov of the Bulgarian National Museum of Natural History remarked, “Numerous external and internal morphological traits, such as the elongated neck between the femoral shaft and head, the specific attachment points for the gluteal muscles, and the robust nature of the external bone layer, share similarities with our bipedal hominin ancestors and modern humans.”
“These anatomical features differ significantly from those of tree-dwelling apes,” he added. “Nevertheless, Grecopithecus did not walk in the same manner as modern humans.”
The environmental context of the Azmaka site indicates a scrub and forest savannah near a braided river system, suggesting that early terrestrial bipeds may have evolved outside of jungle habitats.
The authors hypothesize that the descendants of this group might have migrated from Eurasia to Africa during the late Miocene in response to climatic and environmental changes in the eastern Mediterranean, potentially influencing the ancestry of later African apes and hominids.
Whether the Azmaka femur ultimately reconstructs the geographic story of human origins remains contingent upon future discoveries.
Yet currently, it provides a rare insight into the origins of upright walking within a landscape characterized by seasonal rivers and open forests, millions of years prior to the emergence of the first widely recognized human ancestors in Africa.
Grecopithecus exemplifies a pivotal moment in human evolution, representing the transition from arboreal to terrestrial ancestors, akin to those from approximately 12 million years ago, including Danuvius guggenmosi, discovered at the Hammerschmiede site in southern Germany and more recently in East Africa,” emphasized Professor Bigan.
“In essence, you could classify this as a missing link. Grecopithecus is likely a descendant of apes from the Balkans and Anatolia that existed 8 to 9 million years ago, including Ouranopithecus and Anadrovicius, evolving from Western and Central European ancestors.
“Significant climate fluctuations in the eastern Mediterranean and Western Asia resulted in the periodic formation of extensive semi-desert landscapes between 8 and 6 million years ago,” he concluded. “This prompted a dispersal of Eurasian mammals into Africa, laying the groundwork for the contemporary savannah mammal fauna.”
The team’s findings were published in the November 2025 issue of Paleobiodiversity and Paleoenvironment.

Utilizing advanced X-ray technology, robotics, and artificial intelligence, entomologists have successfully developed interactive digital imagery for 792 ant species across 212 genera.
A detailed Antscan specimen rendering: Eciton Hamatum. Image credit: Katzke et al., doi: 10.1038/s41592-026-03005-0.
To create this extensive digital library, researchers at the Okinawa University of Science and Technology, led by Julian Katzke, gathered ethanol-preserved ant specimens from museums, partner institutions, and global experts.
The team organized the specimens by species and category and transported them to the lab. The Karlsruhe Institute of Technology (KIT) in Germany provided cutting-edge X-ray micro-CT scanning, similar to medical CT scans but with significantly higher magnification.
A synchrotron particle accelerator generated a powerful X-ray beam, enabling rapid scanning of a vast array of samples, while a robotic sample changer seamlessly rotated images every 30 seconds.
This sophisticated process facilitated the production of 2D image stacks, essential for constructing 3D models.
Despite the utility of raw image files, initial depictions of the ant specimens were often distorted, falling short of achieving the realistic models scientists envisioned.
3D imaging allows for the visualization of internal structures, including muscles, nervous systems, and digestive systems, at a micrometer level of resolution.
These models can easily be animated or integrated into virtual reality environments for purposes spanning research, education, and entertainment.
“If we had conducted this project using a standard lab-based CT scanner, it would have taken six years of continuous operation,” Dr. Katzke explained.
“With the KIT setup, we scanned 2,000 specimens in just one week.”
Professor Evan Economo, a researcher at the Okinawa Institute of Science and Technology and the University of Maryland, remarked, “Without these computational tools, completing this project manually would have been nearly impossible.”
Dubbed the Antscan, this initiative could pave the way for future digitization efforts across various species beyond ants.
“The significance of this research extends far beyond ants,” Professor Economo stated. “Once specimens are digitized, we can create libraries that enhance the utilization of biological materials across science labs, classrooms, and even Hollywood studios.”
The team’s study was published in the prestigious journal Nature Methods.

NASA/ESA/CSA’s James Webb Space Telescope has meticulously scanned Jupiter’s circumference, documenting the mesmerizing aurora as it came into view. This dynamic spectacle arises from charged particles traveling along magnetic field lines and colliding with the planet’s ionosphere, creating a stunning glow. Utilizing Webb’s Near Infrared Spectrometer (NIRSpec), researchers captured an intriguing feature of Jupiter’s aurora, known as an auroral footprint. These bright luminescent patterns result from interactions between Jupiter’s Galilean moons—Io, Europa, Ganymede, and Callisto—and the surrounding cosmic environment. Planetary scientists leveraged NIRSpec data to analyze the physical characteristics of the auroral footprints of Jupiter’s innermost moons, Io and Europa, measuring local temperature and ionospheric density in near-infrared light. They uncovered a previously unseen low-temperature structure centered around Io’s bright spots, characterized by an exceptionally high density, likely caused by significant electron flow impacting the upper atmosphere.
Webb’s first spectral measurements of Io and Europa’s auroral footprints reveal unprecedented changes in physical characteristics linked to electron collisions in Jupiter’s atmosphere.

“Previously, these emissions were measured in ultraviolet and infrared wavelengths solely by their brightness,” stated lead author Dr. Katie Knowles, a student at Northumbria University.
“For the first time, we can describe the physical properties of an auroral footprint: the upper atmosphere’s temperature and ion density, which have never been documented before.”
Unlike Earth’s auroras, which primarily result from solar wind, Jupiter’s auroras are influenced by its four major Galilean moons, which generate their own “mini auroras.”
Jupiter’s immense magnetic field rotates every 10 hours, channeling charged particles. In contrast, its moons orbit much more slowly; for instance, Io takes approximately 42.5 hours to complete one orbit.
“The moons continuously interact with the planet’s magnetic field and plasma, driving high-energy particles down magnetic field lines into the atmosphere, forming auroral footprints that trace their orbits around Jupiter,” Knowles explained.
“Jupiter’s auroras are the most potent and persistent within the solar system.”
“Our observations with Webb offer an unprecedented glimpse into how Jupiter’s moons directly affect the upper atmosphere.”
During a 22-hour observation span in September 2023, Webb meticulously scanned around Jupiter’s edge, tracking auroras as they appeared.
Interestingly, they captured auroral footprints originating from Io and Europa, which did not exhibit the typical characteristics of Jupiter’s main auroras, which are generally hotter and denser.
Instead, researchers discovered a cold spot within Io’s auroral footprint that exhibited significantly lower temperatures and unusually high density compared to typical expectations.
Io is notably the most volcanically active celestial body in the solar system, ejecting approximately 1,000 kilograms of material into space every second, thus replenishing the dense plasma enveloping Jupiter.
This ejected material becomes ionized, forming a toroidal cloud around Jupiter known as the Ioplasma torus.
As Io moves through this complex environment, it generates powerful electrical currents that contribute to the brightest regions in Jupiter’s auroras.
The team found that these auroral footprints contained trihydrogen cation densities three times greater than those present in Jupiter’s primary auroras, with some localized areas experiencing density fluctuations of up to 45 times.
“We observed rapid fluctuations in both temperature and density within Io’s auroral footprint occurring within mere minutes,” Knowles noted.
“This indicates that the flow of high-energy electrons impacting Jupiter’s atmosphere is changing at an incredibly fast pace.”
The recorded temperature at the cold spot was only 538 degrees Celsius (265 degrees Fahrenheit), compared to 766 K (493 degrees Celsius or 919 degrees Fahrenheit) in the surrounding aurora.
This cold spot also contained three times the density of material found in Jupiter’s main aurora.
This discovery could have implications extending well beyond Jupiter, posing intriguing questions about other planetary systems.
Saturn’s moon Enceladus similarly generates auroral footprints on Earth, leading scientists to suspect that comparable phenomena may occur there too.
“This research opens up new avenues for studying not only Jupiter and its Galilean moons but also other giant planets and their satellite systems,” Knowles remarked.
“We are witnessing Jupiter’s atmosphere responding to its moons in real-time, providing insights into processes that may occur throughout our solar system and beyond.”
“This phenomenon was only observed in one of five snapshots, prompting questions: how frequently does this occur? Does it vary? How does it change under different conditions?”
The study is published in the journal Geophysical Research Letters.

Representation of Electrons in a Half Möbius Molecule
IBM Research and the University of Manchester
Recent discoveries by chemists reveal an intriguing new molecular structure, which exceeds the complexity of a traditional Möbius strip.
A Möbius strip is a twisted shape that requires an object, like an ant, to traverse it twice to return to its original side.
Igor Roncevic and his team at the University of Manchester have uncovered a more complex half-Möbius molecular structure. This breakthrough could revolutionize the manipulation of molecular shapes and topologies for various applications.
“This molecule is entirely novel and unexpected. Not only is it captivating that we have synthesized a molecule with unconventional topology, but we have also verified that such a structure is feasible, which was previously unconsidered,” he states.
To synthesize the molecule, the researchers combined 13 carbon atoms and two chlorine atoms into a ring on a gold substrate at ultra-low temperatures. Utilizing advanced atomic force and scanning tunneling microscopes, they precisely controlled individual atoms and analyzed the electron properties. Here, electrons do not remain rigidly attached but are diffused in a localized region, resembling tiny waves of matter.
The interactions among these electrons induced unprecedented twists within the molecule. A hypothetical quantum particle would need to revolve around the structure four times to return to its starting point.
Researchers demonstrated the ability to toggle the molecular state from left-handed to right-handed or to untwist it through small electromagnetic pulses. This innovation allows chemists to engineer molecular topology on demand.
To comprehend the newly discovered molecule and its potential existence, the researchers employed simulations on classical computers and an IBM quantum computer. Electron interactions are essential for introducing twists in molecules, which are challenging to simulate accurately on traditional platforms. However, quantum computers, built upon interacting quantum entities, can perform these simulations with greater precision, Roncevic notes.
According to team members, this research illustrates how quantum computing can tackle real-world chemistry challenges. Ivano Tavernelli from IBM emphasizes this point.
“This groundbreaking experiment integrates multiple facets of organic chemistry, surface science, nanoscience, and quantum chemistry,” asserts Gemma Solomon from the University of Copenhagen.
“This is an exciting endeavor that effectively translates abstract topological ideas into the field of molecular chemistry,” adds Kenichiro Itami from RIKEN, Japan, noting the technical significance of the research.
Kim Dong Ho, a professor at Yonsei University in South Korea, highlights the potential applications of shape-switchable molecules in sensor technology, indicating that they could toggle states in response to magnetic fields.
An international team of archaeologists analyzed 85 pottery sherds containing significant food shell remains from 13 archaeological sites in Northern and Eastern Europe, dating from the 6th to 3rd millennium BC. They identified various plant tissues such as wildflowers, legumes, fruits, and herbaceous roots, leaves, and stems in 58 of these sherds. The findings reveal that prehistoric hunter-gatherers exhibited a selective preference for specific plant species and parts, often pairing them with certain animal foods.
Prehistoric Europeans demonstrated careful selection of their plant foods, consciously opting for specific species and combining them with targeted animal foods. This practice may have led to the development of unique tastes, flavors, and textures, facilitated by pottery techniques, thereby motivating their invention and adoption.
Foraging wild plants was a crucial aspect of survival for prehistoric communities. However, direct evidence, including the types of plants foraged and their uses, often remains elusive.
Traditionally, scientists analyze fat residues in ancient pottery to interpret ancient diets. Nonetheless, this method primarily sheds light on animal remains, limiting insights into plant consumption.
In a groundbreaking study, researcher Lara González Carretero from the University of York and her colleagues employed advanced techniques, including microscopy and chemical analysis, to uncover evidence of plant consumption by ancient European hunter-gatherers.
The study evaluated organic artifacts from 58 pottery pieces excavated from 13 archaeological sites in Northern and Eastern Europe, dating between the 6th and 3rd millennium BC.
This innovative approach collected tissue samples from various plant species, including grasses, fruits, leaves, and seeds, frequently found alongside remains of animals, particularly fish and other marine life.
The specific combinations of ingredients varied by region, likely reflecting local cultural practices and available resources.
This important discovery underscores the significant role of plants and aquatic foods in early European diets.
The results confirm that these communities regularly utilized pottery techniques for meal preparation, each developing their own intricate culinary traditions.
“Our findings reveal that the selection of plant foods was highly selective, with hunter-gatherers favoring specific plant species and parts, often combining them with particular animal foods,” the researchers stated.
“These results also suggest that our understanding of plant processing in pottery may be drastically underestimated if we rely solely on lipid residue analysis.”

When an American tragically dies in a plane or train crash, a dedicated independent commission investigates the incident to pinpoint failures and develop strategies to prevent similar occurrences.
In stark contrast, there is currently no similar process in place following deadly floods or hurricanes.
Recently, Rep. Eric Sorensen from Illinois introduced a significant bill aimed at establishing such a review commission to thoroughly investigate weather-related disasters and implement preventive measures for the future.
The proposed legislation, titled the National Weather Safety Commission Act, seeks to establish an independent commission with a minimum of seven members, all possessing relevant expertise in fields like meteorology, social science, and emergency management. The President will appoint them, pending Senate confirmation. This commission is modeled after the National Transportation Safety Board, which investigates all civil aviation incidents and other emergencies.
This proposed commission would have the authority to investigate severe weather events, issue subpoenas for testimony and evidence, and compile reports and recommendations for agencies such as the National Weather Service, Federal Emergency Management Agency, and Army Corps of Engineers.
The idea of a weather disaster review has been a subject of discussion among meteorologists and emergency management professionals for years. However, it gained renewed urgency following the devastating flood in Texas this past July, which resulted in over 130 fatalities, including 27 campers and counselors at a camp along the Guadalupe River.

In the aftermath of the flood, blame quickly shifted among Texas officials, with criticisms directed at the National Weather Service, which was operating with reduced staff due to funding cuts from the previous administration. Questions were raised about the accuracy of rainfall forecasts as well as the effectiveness of local emergency management systems and alert protocols.
“We quickly discovered that political maneuvering was complicating the issue,” Sorensen told NBC News. “We need to implement substantial changes to ensure that a tragedy of this nature does not recur. We will enlist the top experts on an independent board to deliver insights that Congress can use to formulate policies prioritizing public safety.”
As the sole meteorologist in Congress, Sorensen underscores the urgency of this initiative.
“Meteorologists have been advocating for years that we need to enhance our response mechanisms,” Sorensen asserted.
In recent years, Senators Brian Schatz (D-Hawaii) and Bill Cassidy (R-Louisiana) have introduced various proposals aimed at creating similar disaster review boards. Additionally, several Republican colleagues, including former Rep. Katie Porter (D-Calif.) and Rep. Nancy Mace (R-S.C.), are championing comparable legislation. The concept of an independent review body for weather-related incidents dates back to 2006.
Currently, the new bill lacks bipartisan sponsorship.
“This situation is a crucial test for us during this administration and in our currently polarized political climate: Can we still achieve bipartisan collaboration? Can we unite across party lines to enact necessary changes?” Sorensen expressed.

Neil Jacobs, former head of the National Oceanic and Atmospheric Administration (NOAA) appointed by President Trump, endorsed the proposal for an independent review panel.
“Accurate data is essential for post-storm evaluations,” Jacobs mentioned during his Senate confirmation following the Texas disaster. “Drawing from my experiences with the NTSB on aviation incidents, I can envision something similar for weather-related catastrophes, as we require comprehensive data to assess what succeeded, what failed, and the efficacy of warning systems.”
Sorensen confirmed he has collaborated on this bill with Jacobs.
“I believe he is the ideal ally to help propel this initiative forward,” Sorensen stated.
Douglas Hilderbrand, executive director of the American Weather Companies Association, an emerging organization focused on weather forecasting and information delivery, is also collaborating with Sorensen on this legislation.
“Weather is fundamentally a bipartisan concern,” Hilderbrand emphasized. “We remain optimistic about this initiative.”
The bill delineates specific types of events qualifying as weather hazards for the commission’s examination, including any disaster declared by the President under the Stafford Act, along with severe weather events resulting in at least 10 fatalities or 100 injuries. Such events deemed “rapidly occurring” mass casualty incidents are included as well.
The Weather Safety Board would convene a vote within 14 days of the occurrence of such an event to determine whether to initiate an investigation.
The Army Corps of Engineers, Department of Homeland Security (including FEMA), Federal Communications Commission, and NOAA (including the National Weather Service) will be obliged to furnish data and information to the Commission upon request.
The board will have a period of 90 days post-major weather event to draft an interim report, followed by a comprehensive final report due within a 20-month timeframe.

Exploring Unconventional Measurements
Since the Golden Retriever became a quirky unit for measuring ice blocks, our feedback inbox has been flooded with examples of unique and often surprising units of measurement.
Craig Downing, who describes himself as “one of those readers who checks the back of every issue,” shared a fascinating insight about the Rideau Canal in his hometown of Ottawa, Canada. Every winter, the canal transforms into the largest ice skating rink in the world, requiring meticulous snow removal for a smooth surface.
According to a statement from the National Capital Commission, “For every centimeter of snowfall, our crew clears 125,000 kg of snow from the skateway, equivalent to the weight of approximately 450 polar bears.”
Craig expressed his confusion: “I usually visualize snow depth in terms of ‘shovel loads’ or ‘knee-deep driveways.’” Moreover, living in Ottawa, he has yet to encounter a polar bear firsthand, limiting his experience with these majestic creatures.
The average polar bear reportedly weighs around 277.8 kilograms (612 pounds). However, gender nuances play a significant role; adult male bears can weigh between 350 and 600 kg (775 to 1,300 lb), while females typically range from 150 to 290 kg (330 to 650 lb), with some exceptional cases reaching up to 800 kg.
This lack of specification raises questions regarding many unconventional units. Steve Tees submitted a query, stating, “I keep hearing about ‘xxx warehouses’ causing traffic delays. Can someone clarify the size of these warehouses?”
The Sounds We Dread
Various sounds can hinder focus. While nails on a chalkboard are notoriously unpleasant, other common annoyances include loud chewing and vigorous teeth brushing by strangers.
One particularly despised sound is the high-pitched screech produced when adhesive tape is pulled from a surface, which deters many from DIY projects.
But understanding the science behind this noise could help. For example, an experiment published in Physical Review E explores the physics of peeling off cellophane tape. Researchers employed high-speed cameras and microphones to study the tape’s removal speed, discovering that “microscopic cracks travel through the tape at supersonic speeds, producing a shock wave that manifests as a high-pitched screech.”
We eagerly anticipate feedback from follow-up studies aiming to demonstrate quiet tape removal methods.
On Retractions and Their Implications
Our feedback section takes a keen interest in the world of retracted scientific papers. Whether due to questionable graphics generated by AI, manipulated images, or dubious research claims, these cases pique our curiosity.
A prominent example is a 2026 retraction from Pharmacological Research and Prospects. Originally published in 2022, the paper investigated ivermectin—an anti-parasitic drug controversially labeled a potential cure for COVID-19 and suggested for liver cancer treatment. We believe such claims warrant skepticism.
The retraction notice indicated it was “by agreement” between the authors and relevant parties, prolonging the discussion long past its culmination.
It was stated that “the corresponding author was not involved in the submission process, did not sign an open access agreement, and did not review or approve the final manuscript version before submission,” raising serious concerns.
Furthermore, the journal’s investigation uncovered evidence of image duplication from previous publications. This is, without a doubt, troubling.
Yet, the authors maintained, “the conclusions of the article are otherwise unaffected.” This left the first author musing on how conclusions could remain valid despite significant discrepancies.
Our interpretation is clear: once a paper is retracted, it loses credibility, and its conclusions are no longer taken seriously.

Exploring the Medical Potential of Magic Mushrooms
Image Credit: John Moore/Getty Images
A recent placebo-controlled trial has revealed that a single dose of psilocybin, the active compound in magic mushrooms, significantly alleviates symptoms of obsessive-compulsive disorder (OCD). Remarkably, these effects last for at least 12 weeks, suggesting psilocybin could offer enduring relief for OCD sufferers.
“Investing in experiences like travel can disrupt patterns of obsessive thinking and behavior,” notes Dr. David Nutt from Imperial College London, who wasn’t part of the study. “The essence of OCD treatment is to guide individuals towards behavioral change—like reducing the number of times they check the lights from 15 to 2.”
Approximately 1-3% of the population suffers from OCD, a condition marked by distressing obsessions and compulsive behaviors that can severely affect daily life. Conventional treatments often involve talk therapy and antidepressants; however, 40-60% of OCD patients fail to respond to these options.
Other psychedelics, including psilocybin and ketamine, have demonstrated therapeutic potential for various mental health disorders. To explore these possibilities, Dr. Christopher Pittenger at Yale University launched the first randomized, placebo-controlled study focused on psilocybin’s effects on OCD.
The research involved 28 adults with an average of 20 years of OCD experience who had previously undergone at least two failed treatment attempts. Participants assessed their symptom severity using a standard scale ranging from 0 to 40 and were randomly assigned to receive either a single oral dose of psilocybin (0.25 milligrams per kilogram) or niacin (250 milligrams), serving as a placebo.
The psilocybin dose was sufficient to induce a psychedelic experience, often associated with profound changes in perception, cognition, and emotion. “The intensity varies, but it’s generally quite strong,” remarks Pittenger.
Following 48 hours, participants who received psilocybin reported an average symptom score reduction of 9.76 points, while those given niacin showed minimal changes. “The rapid and enduring improvements after a single psilocybin dose are astonishing,” states Dr. Alex Kwan from Cornell University.
After one week, around 70% of participants who took psilocybin experienced a 35% decrease in symptom scores, and this effect persisted through the 12-week follow-up. “Psilocybin outperforms traditional OCD medications in both efficacy and speed,” says Nutt, who was involved in a separate clinical trial that lacked a placebo control. Research indicates that low doses of psilocybin can significantly diminish OCD symptoms.
Kwan suggests that the positive outcomes in individuals who have previously undergone several standard treatments point to psilocybin’s unique influence on the brain, though the precise mechanisms behind its efficacy in managing OCD remain unclear. “Understanding the biology behind its effects could revolutionize the treatment strategies not only for OCD but also for various mental health disorders,” he notes.
One hypothesis suggests that psilocybin enhances brain plasticity, potentially weakening entrenched thoughts that typically dominate an individual’s mindset. This flexibility is a critical challenge with all psychedelic substances, according to Nutt, who previously demonstrated that a single dose of the psychedelic DMT alleviated depression symptoms. “Individuals experiencing depressive thoughts found their thinking became more adaptable post-psychedelic experience,” he states.
Another theory posits that psilocybin recalibrates the brain’s default mode network, influencing areas linked to rumination and self-awareness, according to Pittenger. Research has also shown that a single psilocybin dose can enhance mental health by rewiring neural connections and reducing inflammation.
However, safety concerns regarding psilocybin use have emerged. In a Yale University study, a participant with a history of suicidal thoughts began to actively plan suicide during the trial. Although this risk was later mitigated through standard monitoring, Pittenger emphasizes the necessity for stringent clinical safeguards when administering psilocybin in medical contexts. Comprehensive trials are also needed to validate the drug’s efficacy, safety, optimal dosing, as well as to identify ideal candidates and those at increased risk, he adds.
A recurring challenge in psychedelic research is that participants’ experiences can often reveal whether they received the active drug or placebo. To combat this, researchers administered niacin, which can provoke sensations like facial flushing and elevated heart rate. However, many participants still discerned their treatment, according to Pittenger. “As with most studies of this nature, this presents a limitation,” he concludes.
Leanne ten Brinke’s eye-opening book on dark personalities begins with an unexpected case study of a psychopath. The author highlights a well-known judge presiding over the case of a criminal, emphasizing the complexities of morality.
U.S. Supreme Court Justice William O. Douglas, once a key figure in mid-20th-century liberalism, might exemplify what ten Brinke describes as the “modern definition of a psychopath.” His actions, although not criminal, cast shadows over his legacy, impacting many lives around him.
The diagnosis of psychopathy was discontinued in 1952, attributed to stigma, leading to the adoption of broader terms such as antisocial personality disorder. By the 1980s, psychopathy re-emerged in criminal contexts, with assessments like the Revised Psychopathy Checklist highlighting the lack of empathy in violent offenders, making them capable of high recidivism rates. Individuals identified as psychopaths, although only 1% of the population, are estimated to be responsible for half of the serious crimes, according to ten Brinke.
Ten Brinke, who directs the Truth and Trust Institute at the University of British Columbia, argues that high dark personality traits are not limited to outright offenders. “If we broaden the psychopathy lens, perhaps 10-20% of the population exhibits high levels of traits associated with psychopathy, yet lack the clinical designation,” she states.
In Toxic People, ten Brinke assesses the societal costs inflicted by “predatory individuals” and proposes strategies to mitigate their impact in our lives. However, she presents a crucial caveat.
Over the last two decades, personality psychology has developed the Dark Tetrad framework, combining psychopathy, Machiavellianism, narcissism, and sadism.
Contrary to pop culture’s portrayal of psychopathy as a binary condition, ten Brinke illustrates that it functions on a spectrum. Each individual has varying scores across different traits, with roughly 10-20% exhibiting pronounced dark personality traits, arguably contributing to societal erosion of ethical standards.
However, there’s a silver lining: around 80% of individuals don’t exhibit high levels of these traits. But ten Brinke cautions against complacency, indicating that these characteristics can be influenced by environmental factors.
Through a detailed case study, she discusses how a “culture of corruption” can transform the majority into complicity. “Kind individuals can become vulnerable to dark personalities,” she warns, identifying factors like fatigue or group dynamics as potential triggers for harmful behavior.
The book offers readers useful strategies to shield themselves from toxic individuals, including the establishment of clear boundaries. Yet, it also emphasizes the importance of self-reflection. How can we maintain our moral integrity and resist enabling those with nefarious intentions? Ten Brinke poses critical questions about why we often elevate such personalities in leadership roles.
While some may argue that dark personalities make compelling leaders, ten Brinke debunks this myth in lighter sections of the book. She highlights how research into investment bankers reveals that the most manipulative managers often achieve poorer financial outcomes over time.
Findings suggest that these cunning managers earned 30% less than their cooperative counterparts over a decade. “If you aim to maximize investment returns, seeking a predatory manager may not be your best strategy,” she concludes.
Misconceptions about psychopathic effectiveness arise in workplace dynamics, as dark personalities tend to propagate self-aggrandizing lies. They find reward in deception, furthering their personal agendas. Ten Brinke articulates how such individuals often falsely claim to be exemplary leaders, creating an atmosphere of mistrust.
“
In investment banking, the most malicious and cunning managers earned 30% less than the average. “
Ten Brinke emphasizes our complicity in endorsing dishonest narratives. By refining our own darker traits, particularly strategic Machiavellian thinking, we can better identify deception.
She reminds us that if detecting lies were effortless, deception wouldn’t exist. However, vigilance can pay off. If a few “bad apples” spoil the barrel, the rest of us have the power to prevent decay. Interestingly, ten Brinke hints that certain traits, such as empathy and conscience, can counterbalance darker tendencies, offering a means to reverse corruption.
Challenging the notion that “absolute power corrupts absolutely,” she asserts it applies principally to the worst individuals. Taking ownership of our moral character can lead to rewards.
The pathway to cultivating what she calls “moral Machiavellianism” could significantly enhance our society, moving us beyond the assembly line of psychopathic behaviors.
Amyloid plaques in the brain are a defining feature of Alzheimer’s disease, but what if the roots of the condition start elsewhere in the body?

Alzheimer’s disease has traditionally been believed to originate in the brain. However, comprehensive genomic analysis indicates that inflammation in distant organs such as the skin, lungs, or intestines may initiate the condition, potentially decades before noticeable memory decline occurs. This shift in understanding could shed light on why Alzheimer’s treatments have been largely ineffective. Current drugs intervene too late; a focus on early-stage inflammation in peripheral organs may be crucial.
“As neuroscientists, we tend to focus on the brain, but this study highlights that the brain is interconnected with the body, and changes elsewhere can impact brain function,” states Donna Wilcock from Indiana University, not involved in the study. “Although Alzheimer’s is a brain disorder, we must consider the entire body when discussing its genesis.”
To explore the genetic underpinnings of Alzheimer’s disease, researchers including Cesar Cunha from Denmark’s Novo Nordisk Foundation Basic Metabolic Research Center analyzed genetic data from the European Alzheimer’s and Dementia Biobank, encompassing over 85,000 individuals with the disease and approximately 485,000 without it. They also evaluated gene activity in 5 million single cells across 40 body regions and 100 brain regions.
The study scrutinized 1,000 genes linked to an increased Alzheimer’s disease risk, surprisingly finding these genes were more abundant in organs like the skin, lungs, and digestive system than in the brain. “It was counterintuitive at first because the expression of these risk genes in brain cells seemed low,” notes Cunha. “Our continued analysis revealed their primary presence in other body parts.”
Many of these Alzheimer’s risk genes are tied to immune regulation and are particularly abundant in barrier tissues like the skin and lungs, which defend against bacteria and toxins through inflammatory responses. “This suggests that Alzheimer’s might initiate due to inflammation in these peripheral organs,” Cunha explains. Genetic variations may even dictate the extent of inflammation and its impact on brain health. Hence, individuals with a family history of Alzheimer’s could be more vulnerable to the disease amidst infections or inflammatory episodes.
Interestingly, the highest expression of these gene variants occurs when individuals reach ages 55 to 60. Inflammation during this period seems likely to trigger Alzheimer’s, corroborated by long-term studies from Hawaii. Inflammatory markers rise in individuals in their late 50s, with those in their 70s and 80s exhibiting increased Alzheimer’s likelihood. “A person could suffer from lung inflammation due to a viral infection at age 55, which might initiate Alzheimer’s 30 years later, but the exact mechanisms remain elusive,” Cunha remarks.
Rezanur Rahman, a researcher at QIMR Berghofer Medical Research Institute, has identified a genetic mutation associated with Alzheimer’s that appears concentrated in the skin and lungs. More research is essential to understand their functional role in symptom progression, Rahman states. “Association does not imply causation.”
Previously, the brain was deemed immune-privileged and largely unaffected by inflammatory processes elsewhere in the body. Bryce Vissel from St. Vincent’s Hospital in Sydney, Australia, among those who first proposed inflammation as a trigger for Alzheimer’s, acknowledges that while initially contentious, new evidence supports that peripheral inflammation from infections or injuries may indeed instigate the disease.Infection or injury can affect brain function.
When inflammation occurs, immune cells are activated, releasing signaling proteins like cytokines that can cross into the brain via the bloodstream. An unpublished study by Vissel and his team indicates that cytokines may disrupt neuronal connections, potentially leading to memory impairment.
Concurrently, research has shown that the blood-brain barrier becomes more permeable with age, allowing inflammatory cytokines and immune cells easier access, which might elucidate why inflammation poses more of a risk during mid-life compared to youth, Cunha notes.
Current theories posit that Alzheimer’s disease stems from the accumulation of misfolded beta-amyloid and tau proteins within the brain. Yet, treatments aimed at eliminating these proteins have yielded minimal success, indicating that such accumulation might be a symptom rather than the core issue. “We’ve been trying to treat the result of the disease, not its cause,” Cunha argues.
Cunha likens this to past mistakes in obesity treatments, which initially targeted excess fat directly, failing until genetic research revealed that mutations connected with obesity are often highly expressed in the brain, disrupting appetite and energy balance. This led to the development of the weight-loss medication semaglutide (marketed as Ozempic and Wegovy), which modulates brain pathways to curb appetite.
If Alzheimer’s originates from peripheral inflammation, its treatment would necessitate a paradigm shift, Cunha asserts. Data indicate that midlife vaccinations may offer protective benefits against Alzheimer’s disease. A recent Californian study revealed that adults receiving both doses of the shingles vaccine recommended for individuals aged 50 and older were 50% less likely to develop Alzheimer’s by age 65. Another investigation found that those aged 50 and older treated with the Bacillus Calmette-Guérin (BCG) vaccine for bladder cancer had a 20% reduced risk of onset.
This phenomenon might arise as vaccines bolster the aging immune system and mitigate inflammation, suggests Wilcock. “At age 55, we should invigorate our immune systems and remind them to stay active, as most vaccinations occur in childhood.”
Beyond vaccinations, several lifestyle interventions have been shown to diminish inflammation and avert Alzheimer’s disease. These include adopting a Mediterranean diet, limiting alcohol consumption, exercising, quitting smoking, and managing blood pressure and cholesterol levels.
Professor Cunha emphasizes that the challenge lies in convincing fellow neuroscientists to recognize peripheral inflammation as a potential contributor to Alzheimer’s disease. “I’ve encountered skepticism at academic conferences, being told, ‘If you aren’t focusing on amyloid, you’re not studying Alzheimer’s disease,'” he shares. “After decades entrenched in amyloid research, adapting one’s perspective can be daunting.”
Exciting news from New Guinea! Two marsupial species, believed extinct for over 6,000 years, have been rediscovered.
The Ring-tailed Gliders and Pygmy Longfinger Possums, previously known only from fossils in Australia, were recently observed on the Vogelkop Peninsula in Papua, Indonesia, thanks to the support of local indigenous communities.
Renowned researcher Tim Flannery and his team at the Australian Museum in Sydney undertook years of investigative work, including analyzing peculiar sightings and misidentified specimens, to confirm that these remarkable animals had returned to life.
With photographic evidence and active collaboration with local communities, researchers have verified these animals’ existence. However, their habitat is under threat from logging activities. The specific ecological requirements and range of these rediscovered species are still largely unknown, complicating conservation efforts.
Scott Hucknull, a professor at Central Queensland University, remarked that this discovery is “more significant than finding a live quoll in Tasmania.”
One notable species, the Wow Glider (Thus ayamalensis), is closely related to Australian gliders in the genus Petaurodes. However, distinct features like its prehensile tail and furless ears have warranted its classification into a separate genus.
Local indigenous communities often regard gliders as sacred and protected animals, potentially contributing to their previous obscurity in scientific literature.
“This is one of the most photogenic animals and beautiful marsupials I’ve ever encountered,” Flannery stated.
The Pygmy Longfinger Possum (Dactylonax Kambuyai) is a striking striped creature characterized by an unusually long finger on each hand, which aids its survival.
As Flannery explains, “They possess unique ear adaptations that may help them detect the low-frequency sounds of larvae within wood, allowing them to extract food from decaying trees.”
The exact location of this species remains confidential to protect it from potential wildlife traders.
Flannery cautions against capturing these animals. “They are challenging to maintain in captivity due to their specialized diet—potential pet owners should be forewarned: they don’t last long in confined environments.”
Fossils trace back to approximately 3 to 4 million years ago have been uncovered in archaeological sites in Victoria and New South Wales, Australia, but significant gaps exist in the fossil record, leaving much about the genus a mystery.
Hucknull notes, “The smallest fossil species are undifferentiated from their modern counterparts. The Dactylonax Kambuyai has now been confirmed alive in West Papua.”
“Pocket-sized, peculiar, and adorable,” says Hucknull, emphasizing the ecological significance of this unique species.
Researcher David Lindenmayer from the Australian National University in Canberra commented on the significance of these discoveries while expressing concern over deforestation and habitat destruction in New Guinea. “It provokes questions about what has been lost in Australia due to similar land clearing practices.”
Explore Fossil Hunting in the Australian Outback
Join us on an extraordinary adventure through Australia’s fossil frontier! Once a shallow inland sea millions of years ago, eastern Australia is now a fossil hotspot. Over 13 unforgettable days, travel deep into the hinterland, follow in the footsteps of prehistoric giants, and uncover the secrets of Earth’s ancient history.
While direct evidence of extraterrestrial life remains elusive unless aliens reside close to our solar system, the search for signs of life beyond Earth continues. Astrobiologists typically seek biological markers such as oxygen molecules and ozone in the atmospheres of exoplanets as indicators of potential life.
However, the presence of these chemicals doesn’t guarantee life; they could arise from unknown non-biological processes. More definitive proof of intelligent extraterrestrial beings might come from identifying signs of technological activities in space, known as technosignatures. Established in 1984, the Search for Extraterrestrial Intelligence (SETI) focuses specifically on detecting these technosignatures, particularly through radio signals.
From 2006 to 2020, the SETI@home project collaborated with researchers exploring excessive radio emissions from space via the Arecibo Telescope. Over 14 years, SETI@home collected approximately 400 days of observation time, resulting in billions of detected radio emissions. Unfortunately, most of these signals are likely due to radio frequency interference, benign celestial objects like pulsars or gas clouds, rather than a single extraterrestrial source.
To refine their data analysis, the team recently developed an algorithm designed to filter out interference and pinpoint signals from fixed sources. This advancement positions researchers to re-observe these locations using the 500-meter Fast Radio Telescope.
The algorithm’s goal is to differentiate between natural cosmic signals and potential technosignatures. The team established three criteria for detecting such signals: they must remain stable within a narrow frequency range, exhibit a consistent pulsation, and contain a periodic structure spanning several seconds.
A key consideration is that signals sent intentionally for detection may differ significantly from random radio waves emitted from an alien atmosphere. The principles governing these interactions, such as the Doppler shift, complicate the analysis. Researchers theorize that intelligent civilizations would generate radio signals at a near-constant frequency, easily distinguishable from natural noise.
In their algorithm development, researchers integrated artificial data points that simulate the potential detection of distinct technosignatures, referred to as birdie candidates. If a birdie is flagged for further analysis, it validates the algorithm’s effectiveness. Adjustments to the algorithm’s sensitivity were made based on whether birdies were included or excluded from deeper scrutiny.
To tackle the complexities of data filtering and scoring, the team divided tasks into manageable segments, allowing simultaneous processing on multiple machines. Running the algorithm on 2,000 connected processors, filtering took about 15 hours, while scoring required 1.6 days. Two iterations of the algorithm on SETI@home data were completed, including one with 3,000 birdies for comparative analysis. The Birdie system helped determine which algorithm settings surpassed specified energy thresholds, leading to the identification of 92 targeted signal candidates for re-observation using 23 hours of observation time gained through FAST.
Currently, work is ongoing to analyze these signals, and as of July 2025, researchers have re-observed 80 out of the 92 candidates. Although no direct evidence of extraterrestrial intelligence has been discovered yet, the team remains optimistic that future inquiries utilizing specialized radio telescopes will yield promising results. However, the high costs and demands associated with radio telescope usage mean that SETI will likely continue to collaborate with other astronomers to maximize data collection from available observations.
Recent research highlights an extraordinary extremophile organism, Deinococcus radiodurans, known for its remarkable resilience. This unique microbe can endure the harsh conditions of radiation, frigid temperatures, and arid environments typically encountered during interplanetary transport. New findings suggest that Deinococcus radiodurans also possesses outstanding resistance to the extreme transient pressures generated by impact ejection from Mars. Consequently, this raises the possibility that such resilient life forms could traverse between planets in our solar system following a significant asteroid impact.

Impact craters are prevalent on the surfaces of numerous celestial bodies, with the Moon and Mars being among the most cratered.
Scientific findings indicate that asteroid impacts can propel materials across space, as evidenced by the discovery of a Martian meteorite on Earth.
Furthermore, researchers have long speculated that asteroids could also launch microscopic life forms into space.
This theory, known as the lithopanspermia hypothesis, suggests that life could be ejected into space and potentially land on other planets.
In a groundbreaking study, researchers from Johns Hopkins University, led by Kariat (KT) Ramesh, simulated conditions under which microbes like Deinococcus radiodurans could be expelled into space due to an impact force.
The researchers placed the bacteria between two steel plates and applied pressure with a third plate, demonstrating that these microbes can withstand pressures of up to 3 GPa (30,000 times Earth’s atmospheric pressure).
By analyzing gene expression, they were able to observe biological stress responses within the bacteria under varying pressures.
While samples subjected to 2.4 GPa started to exhibit membrane damage, the unique structure of the bacterial cell envelope accounts for a survival rate of 60% among the microorganisms.
The transcriptional profiles indicated that these resilient bacteria prioritize repairing cellular damage in the aftermath of an impact.
“While we have yet to confirm the existence of life on Mars, if it exists, it likely shares similar survival capabilities,” Ramesh remarked.
“This study suggests that life could endure being ejected from one planet and travel to another.”
“These findings significantly alter our understanding of the origins of life on Earth,” remarked Dr. Lily Chao, also from Johns Hopkins University.
“Our research indicates that life can survive massive impacts and eruptions, implying that life may travel between planets. Perhaps we are all Martians!”
These findings were published in this week’s edition of PNAS Nexus. For detailed insights, refer to the study.

Recent images from the NASA/ESA Hubble Space Telescope and the ESA’s Euclid mission showcase the intricate multi-shell structure of the fascinating planetary nebula NGC 6543, famously known as the Cat’s Eye Nebula.

The Cat’s Eye Nebula, located roughly 4,300 light-years away in the constellation Draco, has intrigued astronomers for decades due to its complex, multi-layered architecture.
“Planetary nebulae,” as they are called, derive their name from their round appearance in early telescopic observations; they are actually colossal gas clouds expelled from stars nearing the end of their life cycle,” the Hubble and ESA astronomers explained.
This insight was initially uncovered in 1864 using the Cat’s Eye Nebula itself. Studying its light spectrum allows scientists to identify individual molecules, a characteristic that differentiates planetary nebulae from stars and galaxies.
Near-infrared and visible-light imagery from the Euclid mission illustrates the arcs and filaments of the nebula’s luminous core, enveloped in a mist of vibrant gas debris that is retreating from the star.
“This ring was expelled from the star prior to the formation of the central nebula,” the astronomers noted.
“The entire nebula is prominently set against a backdrop brimming with distant galaxies, exemplifying how local astrophysical wonders and the farthest reaches of the universe coexist in today’s astronomical surveys.”

Through a wide-field lens, Hubble has captured stunning high-resolution visible-light images of the nebula’s swirling gas core.
The data reveals an intricate tapestry of features that appear almost surreal, including concentric shells, high-velocity gas jets, and dense knots shaped by impact interactions,” the researchers stated.
“These structures are believed to document the transient mass loss from the dying star at the nebula’s center, creating a cosmic ‘fossil record’ of its final evolution.”
“The combination of Hubble’s focused observations and Euclid’s deep-field data not only emphasizes the nebula’s delicate structure but also situates it in the broader cosmic landscape explored by both telescopes.”
“Together, these missions offer a rich, complementary view of NGC 6543, illuminating the subtle interplay between a star’s end-of-life processes and the vast universe that surrounds it.”
The unprecedented mild winter weather affecting large parts of the Western United States combined with the most severe snow drought in decades has experts bracing for an intense wildfire season.
Snowfall across nearly every western state is significantly below average, providing insufficient time for accumulation before the spring thaw. Concurrently, warmer-than-average winter temperatures have contributed to a drier season than typical, escalating concerns over wildfire risks and diminishing water supplies.
“Snowfall in Colorado’s mountains has reached a 40-year low,” remarked Russ Schumacher, director of the Colorado Climate Center at Colorado State University.
Schumacher noted that Colorado’s October-to-February period, usually rich in snowfall, has been “by a wide margin” the warmest on record. In Fort Collins, the number of days hitting 60 degrees in winter has nearly doubled, increasing from 22 to 43.

Consequently, Colorado has not experienced the typical snowstorms, with many storms delivering rain rather than snow, particularly in mid- and low-elevation areas.
This issue extends far beyond Colorado. Measurements of snow water equivalent across the western U.S. indicate that snowpack levels are well below average, with some basins recording less than 50% of their usual levels.
“Most regions are below 50% of average, meaning they would typically have more than double the snow,” stated Noah Molotch, a geographer from the University of Colorado Boulder.

Molotch, alongside his team, monitors snowfall across the western U.S. and reports that this year is among the driest on record, with only the southern Sierra Nevada, parts of northwestern Wyoming, and minor regions in Montana, Idaho, and northern Washington experiencing near-normal snowfall.
Numerous areas continue to suffer from a “severe snow drought,” he added.
Research indicates that snow drought and premature snowmelt could intensify the wildfire season during summer. When forests and grasslands receive significantly less snow, or if the snow melts sooner, there’s increased potential for vegetation to dry out and serve as fuel for wildfires.
In Colorado, the recent Blue Bell Fire led to an evacuation order in Boulder last weekend, burning approximately 1.5 acres. Although quickly contained, it highlighted the state’s vulnerability under warmer, drier, and windier conditions.
“The absence of severe fire weather isn’t the issue,” Molotch stated. “These snow drought conditions clearly contribute to a potentially severe wildfire season.”

Schumacher pointed out that climate change could be influencing these trends. While linking yearly snowfall variations directly to global warming can be challenging, it is clear that climate change increases the likelihood of above-average temperatures, even in winter.
“Attributing the lack of precipitation to climate change is complex, but extreme temperatures exhibit a clear connection to global warming,” he stated.
Diminishing mountain snowpack poses a serious threat to water supplies in the West. The snow that accumulates in winter is essential for replenishing rivers and streams that support cities, agriculture, and hydroelectricity.
“This is critical for our water supply,” noted Molotch.
Without a stabilization of snow levels, the reservoirs in the western U.S. risk running dry.
“These challenges aren’t unique to Colorado. The Colorado River Basin is in a particularly precarious position as it is already overallocated, leading the federal government to face tough decisions regarding reductions in allocations,” Molotch explained.
The upcoming weeks could bring substantial snowfall to parts of the West, including Colorado and Utah; however, the current forecast offers little optimism.

Schumacher expressed a growing sense of resignation, as his winter optimism fades.
“As we approach early March, unfortunately, time is running out for a turnaround,” he lamented. “The hope now is that this year will merely be a disappointing one and not one for the record books.”
Cats possess a remarkable ability to adjust their bodies mid-fall, allowing them to land gracefully on their feet, a phenomenon known as the cat righting reflex.
According to Yasuo Higurashi from Yamaguchi University, the cat’s thoracic spine is especially flexible, providing the agility needed to rotate their body during a fall.
It’s widely understood that cats almost always land on their feet. When you drop a cat upside down, it instinctively twists its body to ensure a safe landing.
This impressive skill has puzzled scientists for over a century, leading to three primary theories about how cats achieve this feat.
The first theory suggests they use a propeller-like motion with their tails, turning their bodies in the opposite direction. However, Greg Barr, a physics author, notes that the tail isn’t crucial, as cats can accomplish this without it. His work, Falling Cats and Basic Physics, supports this observation.
The second theory, the bend-twist model, posits that cats bend their bodies at nearly right angles. This allows their front and back halves to rotate independently, enabling all four legs to align correctly upon landing.
The third model, referred to as tuck-and-turn, illustrates how cats first rotate their front half while extending their hind legs, then switch positions to ensure safe landing.
To explore feline behavior, Higurashi and his team conducted two experiments. The first involved assessing the spinal flexibility of five deceased cats, revealing that their thoracic spines can rotate three times more than their lumbar spines.
The researchers filmed high-speed videos of two adult cats falling from one meter, finding that the front half completes its rotation slightly faster than the rear.
According to Gbur, these experiments made him reconsider the significance of the tuck-and-turn model, suggesting a stronger reliance on the bending and twisting motions during a fall. His observations indicated that the front of a falling cat appears to orient itself before the back.
These models are not mutually exclusive, as Gbur emphasizes, pointing out that nature often employs complex and effective methods rather than simple solutions.
Interestingly, the study revealed a tendency for cats to rotate predominantly to the right when falling. While one cat consistently displayed this behavior, another did so six out of eight times. Gbur speculates that this may relate to the asymmetric arrangement of a cat’s internal organs, affecting their rotational preferences.

Rising Sea Levels: Increased Risk of Storm Surge Flooding in Coastal Cities

Many studies on the impact of future sea level rise have neglected to acknowledge that current sea levels are higher than previously estimated, resulting from a significant “methodological blind spot.” This oversight indicates that flooding and erosion may commence sooner than anticipated.
Katarina Seeger and Philip Minderhoud, researchers at Wageningen University in the Netherlands, evaluated 385 peer-reviewed studies addressing coastal vulnerability. They found that 90% of these studies failed to consider critical factors—such as ocean currents, tides, temperature, salinity, and wind—when assessing sea level variations. This oversight led to an average underestimation of coastal water levels by 24 to 27 centimeters.
Addressing this gap could potentially increase projections of individuals likely to experience flooding, estimating an increase of up to 68%, impacting approximately 132 million people by 2100. Areas significantly affected include Southeast Asia and Oceania, which often feature sea levels averaging a meter higher than previously calculated, with some regions seeing several meters’ difference.
“If representatives from these vulnerable regions attend global discussions to seek assistance, it may be frustrating, as their risks are grossly underestimated. This scientific miscalculation could affect outcomes for future generations,” Minderhoud stated during a briefing.
While predictions suggest that sea levels may rise by as much as 1 meter by the century’s end, many studies begin with baselines that are inaccurately low. Thus, the adverse effects will likely manifest sooner than expected.
Of the studies evaluated, 46 were referenced in the latest report from the Intergovernmental Panel on Climate Change (IPCC), the premier source on global warming impacts, including rising sea levels.
The Earth’s rotation causes it to bulge at the equator, while denser mantle sections exert a greater gravitational pull on overlying water. To accurately determine the elevation of a specific area, measurements must be compared to the geoid, which depicts mean sea level worldwide.
However, in some regions, actual sea levels can be several meters above the geoid due to wind and ocean currents accumulating water or thermal expansion caused by rising temperatures. Additionally, coastlines may shift due to sediment deposition in rivers or groundwater extraction beneath coastal areas.
Instead of comparing satellite observations to the geoid for insight into coastal water levels and land elevation, many researchers relied on unadjusted geoid sea levels. Even those who attempted calculations often encountered errors caused by differing geoid models for land and ocean elevations. Alarmingly, less than 1% of surveys accurately determined the current sea level at the coastline in question.
“The Coastal Research Community may not have full access to these critical sea level datasets as we are primarily focused on the coastal land aspect,” Seeger remarked during the briefing.
Climate scientists and oceanographers must collaborate more closely with geographers and environmental scientists who assess coastal impacts, emphasized Matt Palmer from the UK’s Met Office.
“It could be said that the crucial final details got lost in translation,” he noted. “Ensuring that the last mile of information is handled adeptly is vital; otherwise, the integrity of the entire effort is compromised.”
The implications of this issue extend to matters of climate justice, said Palmer. The underestimation of sea levels is particularly critical in low-income nations, including various deltas in Africa and Asia. Limited data on gravity fluctuations and lower geoid accuracy contribute to this challenge in regions that are most susceptible to rising sea levels.
The scientific community advocates for enhanced data collection in low-income regions, particularly through the installation of tide gauges for accurate sea level measurements, according to Joan Williams from the UK National Marine Centre.
“Coastal sea levels are influenced by various local factors, necessitating long-term, well-calibrated regional measurements as the gold standard,” she stated.
“Where Are They?” is the question posed by the renowned Italian-American physicist Enrico Fermi during a discussion with a colleague in the early 1950s, hinting at the existence of extraterrestrial life. Fermi conducted calculations suggesting that alien civilizations should exist and have visited Earth in the past. He argued that the absence of extraterrestrial outposts raises important questions about civilization itself.
For decades, astronomers have referenced this pivotal conversation to explore the Fermi Paradox, which questions why we don’t see signs of other civilizations in the galaxy if they exist. Various hypotheses have emerged, including the Great Filter theory, suggesting a barrier that prevents civilizations from achieving the technology to communicate with one another. Alternatively, the Zoo Hypothesis posits that extraterrestrial beings are aware of humanity and opt not to make contact to avoid confusion. It is also possible that aliens are already among us or that unidentified aerial phenomena (UAP) or interstellar objects like ‘Oumuamua could indicate alien presence.
Some solutions to the Fermi Paradox involve assumptions regarding technological growth, evolution, or intelligence itself. Recently, researcher Robin HD Corbett suggested a more routine solution. His argument is based on the Copernican Principle of Mediocrity, which implies that if alien civilizations are akin to humans, it’s not surprising we haven’t encountered them.
Corbett presents two main considerations for a “radical secularity” solution to the Fermi Paradox. Firstly, there are limits to technological advancement; even if alien civilizations are more advanced, they lack faster-than-light travel or other impossible technologies. Secondly, while numerous alien civilizations may exist, they are not ubiquitous.
Regarding technology, Corbett points out that the laws of physics inhibit any civilization from developing a warp drive to quickly traverse the galaxy. Practical limitations, including engineering challenges and ecological concerns, compel civilizations to pursue sustainable technologies rather than pursuing grand projects detectable from afar, like an artificial ring around a star or radio beacons broadcasting for thousands of years.
The existence of civilizations similar to ours carries significant implications. If they exercise similar rational thought, guiding their space exploration decisions with cost-benefit analyses, they might find that the effort required to explore other civilizations may outweigh the benefits, especially without groundbreaking technology.
Corbett further claims that space exploration would likely be conducted by autonomous, perhaps self-replicating, machines known as von Neumann probes equipped with advanced AI, capable of traveling at 1/1000th the speed of light. Concerns about uncontrollable AI escalation may increase costs, leading civilizations to limit their exploratory efforts.
Corbett concludes that if alien civilizations are located far from Earth, they may have abandoned their search for others millions of years ago, leaving us in silence. Scientists, particularly those working on the new wireless array, should be mindful that extraterrestrial beings may closely resemble humans.Star Trek‘s Vulcans suggest limitations on future technologies, further complicating our quest for contact. Corbett also posits that UAPs discovered on Earth are likely not alien in origin, concluding that extraterrestrials may find humans too ordinary to warrant their attention.

The largest mass extinction in history led to the loss of over 80% of marine life. Remarkably, certain ecosystems continued to thrive, and various species, including apex predators, managed to survive this catastrophic event.
This research indicates that the survival of specific ecosystems was influenced by their unique species compositions. A similar pattern may be observed in today’s marine ecosystems, which are under significant threat from climate change.
Approximately 252 million years ago, the end-Permian extinction was likely triggered by extensive volcanic eruptions in present-day Siberia, causing rapid global warming and diminishing ocean oxygen levels. Notably, some groups, like trilobites and eurypterids (sea scorpions), faced total extinction, while others experienced dramatic losses. In the aftermath, new species groups emerged, including dinosaurs and ichthyosaurs.
Despite the extinction of numerous species, researchers speculate that ecosystems may have become less complex. A functioning ecosystem relies on diverse interdependent species—plants that produce energy, herbivores that consume them, and predators that eat herbivores. Top predators may face extinction as they depend on prey for survival. Thus, a significant extinction event, such as the one at the end of the Permian, would simplify ecosystems.
To investigate this hypothesis, Baran Kalapunar and a team from the University of Leeds assessed preserved remains from seven marine ecosystems globally, both before and after the extinction. They analyzed the ecosystem structures based on the species present. Kalapunar declined to provide an interview as the study is yet to undergo peer review.
Even with species losses reaching 96%, five of the seven ecosystems sustained at least four trophic levels.
In regions, particularly near the poles, slow-moving herbivores caused the most significant damage, while free-swimming organisms, such as fish, were less severely impacted.
Ecosystem recovery varied based on proximity to the equator. Tropical ecosystems were primarily populated by low-trophic-level species, while those nearer to the poles experienced the addition of trophic levels as fish predators relocated away from extreme heat near the equator.
These findings imply that present-day marine ecosystems also respond differently to climate change and other anthropogenic impacts.
“I’m not aware of any other study that encompasses so many regions,” states Peter Roopnarine from the California Academy of Sciences in San Francisco. He concurs with the conclusions that many ecosystems sustain trophic levels despite extinctions, as previous smaller-scale studies indicated.
However, Roopnarine cautions against placing too much emphasis on the specifics of researchers’ ecosystem models. The fossil record does not clarify which organisms survived and which did not, requiring researchers to combine all photosynthetic organisms together without predicting outcomes if these species became extinct. “These findings are firmly supported by the fossil record, yet it remains incomplete,” he remarks.

X and Y chromosomes engage in competition to favorably skew sex ratios.

Have you ever noticed a family where almost all the children are boys or girls? While often just random chance, a detailed analysis of a Utah family tracing back to the 1700s offers a fascinating biological explanation: the “selfish” Y chromosome may suppress female births.
According to James Baldwin Brown at the University of Utah, “This family is of great significance. Selfish genes, like the ones highlighted, have been documented across various organisms, yet studying them in humans remains challenging.”
In most mammals, male cells feature one X and one Y chromosome. During sperm formation in the testes, half receive Y chromosomes and half receive X chromosomes, leading to a theoretical 50:50 male-female birth ratio. However, certain chromosome variations can skew this outcome, producing an unequal number of male or female offspring. For instance, some selfish chromosomes hinder other sperm’s capability to reach the egg, while others eliminate non-selfish sperm. “This phenomenon has puzzled scientists for over a century,” adds Nitin Phadnis, also from the University of Utah.
The competition between selfish X and Y chromosomes can significantly skew sex ratios. Such variations are not just limited to humans; selfish chromosomes affecting sex ratios have been observed in various animals. The challenge lies in identifying currently active selfish chromosomes. “Even having several boys consecutively can often occur by chance,” Baldwin-Brown clarifies.
To prove that sex ratio bias is not a mere coincidence, it requires analyzing multiple generations. Using the Utah Population Database, which catalogs millions, Baldwin-Brown, Phadnis, and their team focused on 76,000 individuals.
The researchers employed two distinct statistical methods, both isolating the same families as significant outliers. Over seven generations, 33 men shared the same Y chromosome, resulting in 60 male and 29 female offspring out of 89 children.
Due to data anonymization, genetic analysis remains elusive. “It would be invaluable to connect with these individuals to sequence their sperm and investigate further,” says Baldwin-Brown. “However, navigating the ethical requirements and funding this endeavor is quite challenging.”
Sarah Zanders from the Stowers Medical Research Institute in Missouri speculates that a selfish Y chromosome might be at play but acknowledges the sample size is still too small for conclusive evidence. While analyzing microbes, her team detected significant sex ratio biases, yet larger sample evaluations yielded less remarkable findings.
Infidelity poses an additional complication, Zanders noted. “Though I’m not a human expert, I suspect many father assignments could be iffy,” she reflects. Baldwin-Brown acknowledged the possibility. “Despite this, there remains robust data that appears trustworthy,” he assures.
Understanding the selfish Y chromosome extends beyond theoretical implications, Phadnis suggests. Such mechanisms could be a factor in rising male infertility rates, as a trait that diminishes half of all sperm would severely impact fertility. Moreover, studies indicate selfish chromosomes may induce infertility in certain individuals.
The research team now aims to analyze sperm samples for discrepancies in the X and Y carrying sperm ratios.
This latest examination focuses on the selfish Y chromosome for various reasons. It is simpler to trace male lineage, and another potential cause for a higher female birth ratio could stem from a deadly mutation rather than merely a selfish X chromosome.
Selfish genes aren’t exclusive to X and Y chromosomes. More broadly, DNA that enhances inheritance probabilities above 50% is referred to as a gene drive and has been discovered in various species. CRISPR technology can create artificial gene drives, with potential applications in combating malaria and controlling pest populations.
Let’s begin with an important fact: No matter what you’ve heard, you are not eating the equivalent of a credit card’s worth of microplastics every week.
You can read more about the confusion around this assertion in the article here.
However, the claim has sparked concerns, particularly after multiple studies reported microplastics accumulating in various environments—ranging from the highest mountains to the deepest ocean trenches, and even in isolated polar regions. Microplastics have also been detected in human tissues, including the heart, liver, kidneys, breast milk, and bloodstream.
Given their prevalence and potential health implications, it’s understandable to be worried, but is it truly warranted?
The ubiquity of microplastics can be traced back to the remarkable properties of plastics. The invention of Bakelite in the early 20th century marked a shift in how materials were produced—created from synthetic compounds rather than sourced from nature.
As plastic became more affordable and widespread, its applications flourished, impacting food packaging, electronics, medical devices, and more. Unfortunately, this durability also leads to a significant environmental issue; microplastics have been released into ecosystems for over a century, persisting for long periods. Consequently, these particles have made their way into the tissues and bloodstreams of various species, including us.
These microplastics are often present in everyday items we consume, such as salt, beer, and drinking water, as detailed here.
Yes, microplastics could likely be within you, but there’s no need to panic just yet. Assessing the health implications of pollutants involves several factors.
Firstly, consider the size of the microplastics, which varies significantly. Secondly, what concentration is required to elicit effects? Lastly, we must examine whether the effects are indeed harmful. Much of the current research is animal-based, which raises questions about its applicability to humans.
Microplastics and Credit Cards
In recent years, alarming headlines have often cited vague information about microplastic sizes or relied on inflated studies that use unrealistically high doses, not reflective of typical human consumption.
For example, widely circulated claims suggested that the average person ingests around 5 grams of microplastics a week—the amount in a credit card. This assertion stems from a 2019 study that employed questionable methodologies and can easily be debunked.
According to a more accurate assessment, most individuals consume only around 0.0041 milligrams per week—less than a grain of salt. This slower rate suggests that it would take over 1.2 million weeks, or 23,000 years, to consume the equivalent of one credit card’s worth of plastic.
If you were immortal, perhaps you could worry about it.
Research indicates that the average person accumulates about 12.2 milligrams of microplastics in their lifetime, but only around 41 nanograms might actually be absorbed by the body based on a study by the same researcher.
New concerns have also emerged surrounding the methodologies used to investigate microplastics within bodily tissues. Some studies employ vaporization techniques that analyze smoke for microplastics, potentially leading to false positives due to similar chemical structures released from fat.
Effects of Microplastics on Human Health
While we know that microplastics are present in our bodies, their effects remain unclear. Some studies indicate that microplastics may lead to behavioral changes and inflammation in animal models; however, these studies often utilize unrealistically high doses—1 gram per day for rodents, for example.
Other studies in pigs showed that a weekly dose of 1 gram affected gene expression and induced oxidative stress in the pancreas, yet this dosage vastly exceeds typical human exposure.
Reports from the World Health Organization have cautioned that most animal studies utilize concentrations of microplastics well above what humans typically encounter. Moreover, microplastics are processed differently in human bodies compared to rodents, complicating data interpretation.
Preliminary human studies have detected microplastics accumulating in plaques and have correlated the presence of these plastics with higher instances of heart attacks and strokes. However, correlation does not entail causation—it’s critical to avoid jumping to conclusions.
Investigating the impact of microplastics on human health is multifaceted. While these small particles carry chemicals capable of disrupting bodily processes, it is essential to recognize that not all these chemicals are absorbed immediately. Studies have demonstrated that the amount of chemicals leaching from microplastics is minimal under average conditions, as addressed in this report. Additionally, the body can excrete certain chemicals, negating long-term accumulation risks.
Concerns also revolve around the potential introduction of other hazardous substances linked to microplastics. Moreover, they may disrupt immune functions or even cause cell damage and inflammation. However, comparative assessments regarding the risks of microplastics versus other pollutants—such as air quality or dietary excesses—remain uncertain.
While it’s natural to fear the health risks posed by microplastics, we need definitive evidence to gauge their danger accurately. This discussion taps into our anxiety surrounding pollution. Just because we don’t consume a credit card’s worth of plastic each week doesn’t mean that the issue isn’t serious. However, the field of microplastic research is still nascent, and comprehensive data on their effects in humans is lacking.
Until further research emerges, I’ll focus my concerns elsewhere.
