Why not come face to face with the world’s most fearsome dinosaur? Let’s poke fun at where it’s most sensitive: its tiny little arms.
Scientists have long debated the reasons behind the tyrannosaurus rex’s small limbs. While they agree that these arms were nearly useless, the evolutionary triggers for their size have remained a mystery—until now.
New research conducted by University College London (UCL) and the University of Cambridge analyzed 82 species of theropods, a group of bipedal, primarily carnivorous dinosaurs. The study revealed that as the head and jaw of the tyrannosaurus grew larger, the arms became progressively smaller.
This indicates that tyrannosaurus and other predatory dinosaurs evolved to rely on their powerful jaws and heads for hunting rather than their claws. Consequently, their arms diminished over time, eventually appearing disproportionately small compared to their massive heads and bodies, leading to a plethora of jokes about their little arms.
Researchers have long recognized that while tyrannosaurus rex‘s arms are vestigial—having lost their original function—this newfound correlation between arm reduction and head enlargement marks a significant development in our understanding.
The study published in Proceedings of the Royal Society B discovered that smaller arms correlate more strongly with the evolution of large, powerful skulls and jaws than with the dinosaur’s overall size. This means that having smaller arms isn’t simply a matter of size.
As lead author Charlie Roger Scherer, a PhD student in UCL Earth Sciences, puts it: “The head replaced the arm as the primary method of attack. It’s a ‘use it or lose it’ scenario; if the arms aren’t useful, they will eventually shrink.”
He adds, “These adaptations often occurred in environments rich in large prey. Trying to grab a 100-foot-long sauropod with claws is impractical. Instead, attacking and restraining it with powerful jaws would have been much more effective.”
Interestingly, while we commonly associate small arms with tyrannosaurus, there were several other theropods that skipped out on upper-body workouts. For instance, the Carnotaurus had even smaller arms than the tyrannosaurus.
Regardless of size, the study indicates that some smaller theropods also had similarly potent heads and tiny limbs, highlighting the adaptability of these fascinating creatures.
Recent analysis of data from NASA’s Juno spacecraft reveals that Jupiter’s bow shocks not only deflect the solar wind but also serve as potent particle accelerators, propelling electrons to relativistic energies of at least 1 MeV.
As celestial bodies traverse streams of charged particles, their magnetic fields act as barriers. This interaction results in incoming particles being slowed and redirected, creating a ‘bow shock.’ Just beyond this boundary lies the foreshock, a dynamic area where magnetic forces can accelerate particles to speeds approaching that of light. Image credit: Ben C. Smith, Johns Hopkins Applied Physics Laboratory.
A shock is a disturbance caused by an object moving faster than the local speed of sound through a medium, leading to a sudden change in pressure at the interface.
Jupiter’s bow shock, for instance, arises where the planet’s magnetic field interacts with the solar wind, similar to how a ship’s bow creates waves in the water.
Most shocks in space plasma are collisionless due to low particle density, which prevents direct collisions and energy transfer through heat. Instead, electromagnetic forces govern these interactions.
Collisionless shocks are believed to be key sites where cosmic rays are accelerated to near-light speeds in a process termed relativistic electron acceleration.
Despite this understanding, scientists have faced challenges in directly observing and confirming the mechanisms behind these structures.
“Since the discovery of cosmic rays over a century ago, astronomers have been tracing their origins,” stated Dr. Savas Raptis from Johns Hopkins University Applied Physics Laboratory and his colleagues.
“These high-energy particles originate from various sources, including supernovae and solar eruptions.”
“When solar cosmic rays interact with Earth, they can induce space weather impacts that disrupt satellites, communications, and electricity grids.”
“The NASA mission illustrated how some electrons attain high energy levels in regions near Earth known as foreshocks, where solar particles first encounter Earth’s magnetic field.”
“Scientists have long suspected that this same acceleration process occurs in the foreshocks of other planetary bodies and astrophysical systems, but confirmation has been elusive until now.”
The research team analyzed data gathered by Juno during its approach to Jupiter on October 1, 2023.
Before passing through the bow shock, Juno traversed a foreshock, a turbulent area where the solar wind initially senses the planet’s magnetic field.
Over approximately 20 minutes, Juno detected a significant bubble-like disturbance identified as a foreshock transient.
The spacecraft employed three onboard instruments to measure electrons accelerated to energies reaching up to 1 MeV within this transient structure.
“By utilizing these observations and supplementary data from our solar system, we propose a universal scaling law for the Hyras limit, empirically linking the size of observable transients to maximum particle energy,” the authors concluded.
“Applying this model across diverse environments, from planetary bow shocks to protostellar jets and supernova remnants, suggests a range for maximum achievable particle energies from the MeV scale to tens of GeV and TeV, offering a method for constraining maximum cosmic ray energies in astrophysical shocks.”
The team’s paper was published in the journal Nature on June 3, 2026.

Approximately 66 million years ago, the end-Cretaceous extinction event drastically altered Earth’s biodiversity. However, the implications for marine fish remain a topic of debate due to gaps in the fossil record. A recent study conducted by paleontologists reveals a collection of marine fish fossils from the 62.2 million-year-old Quraya 3 site in Egypt’s eastern desert, shedding light on this transition. These discoveries include the earliest known fossil skeletons of horse mackerel, moonfish, and pipefish, which are relatives of seahorses.

“The fossil record is limited, and there exists a substantial 10 million-year gap,” stated study lead author Sanaa El-Sayed, a doctoral candidate at the University of Michigan.
“While we know asteroids impacted marine environments, it remains unclear how these events shaped the ocean’s inhabitants, particularly modern fish species.”
“This site is remarkable in addressing when, where, and which species existed in modern oceans just a few million years post-dinosaurs.”
At the Quraya 3 site, El-Sayed and her colleagues identified fossils from 21 distinct fish species spanning nine orders.
“Most of these fish are percomorphs, a dominant group in today’s oceans, yet relatively rare during the dinosaur era,” noted co-author Professor Matt Friedman, director and curator of the University of Michigan Museum of Paleontology.
“This discovery reinforces the theory that a biological crisis tied to the end-Cretaceous mass extinction led to the loss of certain fish types, allowing modern-looking fish groups to flourish soon after.”
The “Patterson Gap,” named after the paleontologist who studied it, identifies the fossil-poor section of the record before and following the mass extinction at the end of the Cretaceous.
This gap obscures our understanding of how fish species were affected by extinction events.
“This early Cenozoic gap raises two critical questions,” added Professor Friedman.
“First, did the fish we traditionally associate with extinction at the end of the Cretaceous truly not continue into the Paleogene period? Or were they simply overlooked due to poor records?”
“Second, when did recognizable modern groups actually emerge?”
“This gap represents an extensive timeframe in which the details remain unclear, frustratingly coinciding with one of Earth’s most intriguing historical periods.”
“Our remarkable findings provide insights into this critical epoch.”
“We found numerous preserved skeletons; however, the species long believed extinct were absent.”
“Our research indicates that their absence likely reflects genuine extinction occurring around the end-Cretaceous event, rather than simply a record deficiency.”
“Moreover, this site offers concrete evidence that many modern fish groups were established quite early in the evolutionary timeline.”
The research team also contemplated the broader implications of their findings in the context of the fossil record following the end-Cretaceous mass extinction.
Upon comparing their findings with data from additional fossil deposits, they noted that most percomorphs discovered shortly after extinction events predominantly thrived in tropical regions.
Conversely, fewer percomorphs appeared at high latitudes, becoming more common only significantly later.
“It appears they predominantly developed in tropical regions, later dispersing to higher latitudes as climatic conditions changed.”
“As we enhance our fossil record, these conclusions will be put to further rigorous testing.”
These significant findings are published in this week’s edition of Scientific Progress.

Towering majestically in the mountains of northern Taiwan, the Taiwan Crypmeroid—a colossal conifer from the Cypressaceae family—has ancestors that date back over 100 million years, making it the tallest known tree in East Asia.
Known colloquially as the Heavenly Sword, this remarkable tree stands at an impressive 84.1 meters tall, nestled within the Peishan Mountains of northern Taiwan.
Its monumental height was verified in 2023 when an adventurous climber scaled the trunk and dropped a tape measure from the tree’s crown.
“Taiwan, historically referred to as Formosa, harbors a secret deep within its rugged landscape, a unique ecosystem that supports ‘giant’ trees exceeding 80 meters in height,” stated Dr. Rebecca Chia-Chun-Su of the Taiwan Forestry Research Institute and her team.
“Since 2014, our committed group of ‘Taiwan Tree Explorers’ has been on an expedition to locate and document these towering giants.”
“This team comprises professional tree climbers, ecologists, geologists, and remote-sensing specialists.”
“In 2023, our perseverance culminated in the discovery of the king of the island’s forests, an 84.1-meter-tall Taiwan Crypmeroid.”
“This titan currently holds the title of the tallest tree in East Asia.”
“For the indigenous Rukai people, these majestic firs are affectionately known as the tree that touches the moon.”
As part of their project, researchers created a national tree canopy map using aerial laser scanning data, initially identifying 57,065 potential giant trees.
However, the steep cliffs led to numerous false positives. For instance, a tree recorded as 90 meters was actually only 25 meters tall due to its sheer cliff location.
To streamline the verification process, they sought assistance from the public.
About 372 online volunteers analyzed laser-scanned profile images of trees, successfully narrowing the candidate list to 4,736 while effectively eliminating 92% of the manual verification workload typically required by experts.
The final results indicated the presence of 941 giant trees exceeding 65 meters tall, primarily concentrated in mountainous cloud forests situated 1,500 to 2,500 meters above sea level across Taiwan.
Nine out of the ten tallest trees are over 70 meters in height and all are classified as Taiwan Crypmeroid.
Scientists have raised alarms about climate change elevating cloud bases in Taiwan’s mountains, jeopardizing the forests where these giants thrive.
The frequency of typhoons striking Taiwan has increased by 35% over the past four decades, while flood and landslide risks intensify, threatening trees that thrive in steep river valleys.
During the expedition, illegal logging of native trees was also uncovered, even within designated protected areas.
“Large, ancient trees play a significant role in forest ecosystems,” the researchers noted.
“These giants serve as major carbon reservoirs; one might sequester as much carbon as an entire grove of mid-sized trees.”
“They also create vital habitats and modify the microclimate, thus sustaining forest biodiversity.”
“Despite their size, these magnificent trees are uniquely vulnerable to climate change,” they added.
“Human activities remain a persistent threat. Though over 95% of identified giant trees are situated within protected areas, their remote locations complicate monitoring efforts.”
“During ground surveys, evidence of illegal poaching of native trees was discovered.”
“This underscores that while public protection is crucial, community vigilance is equally important.”
The team’s research paper will be published in the journal Forest Frontiers and Global Change.

In 2018, a Chinese researcher faced global condemnation after announcing he had used CRISPR technology to create three gene-edited children. The scientific community’s primary concern revolved around the risks of using CRISPR, particularly its potential to cause harmful mutations.
Recent advancements in gene editing show promise, particularly with a refined version of CRISPR called base editing. This technique allows researchers to edit healthy embryos with a significantly reduced risk of unwanted mutations. However, ethical and scientific hurdles remain before considering its broader application.
Human DNA consists of double strands, and the original CRISPR method employs a protein known as Cas9. This protein utilizes a guide RNA to target specific genomic locations, where it creates cuts in both strands. Unfortunately, such repairs by cells can lead to small mutations that may disrupt gene function.
Thus, even when the CRISPR-Cas9 system is successful, its inherent risks include major mutations and chromosomal abnormalities due to incorrect DNA repair.
Improvements, such as CRISPR base editing, now allow for more precise modifications by changing a single DNA base and cutting only one strand. Such advancements have demonstrated life-saving potential in ongoing clinical trials, particularly as treatments for conditions like hypercholesterolemia.
However, gene editing in embryos differs vastly from treating diseases in adults. In adult therapies, successful editing in just a fraction of cells may suffice. Yet, in an embryo, precise editing is critical, as every cell in the body will derive from it.
In 2017, a Chinese study explored base editing in abnormal human embryos, yielding positive results with minimal unintended changes.
More recently, Columbia University’s Dieter Egli and his team conducted a larger study using healthy two-cell embryos, achieving varied results. They found that one modification succeeded in three-quarters of cells without unintended changes, while another, less effective modification caused problems in about half of the cells.
The researchers attribute these discrepancies to the design of their guide RNA, emphasizing the need for better optimization to minimize off-target effects.
One critical challenge remains: the issue of mosaicism. If only some cells in an embryo undergo the intended gene edit, diseases still risk manifesting. This raises concerns, as evidenced by the potential mosaicism in the three gene-edited children from China.
Currently, there’s no foolproof way to confirm the absence of mosaicism in gene-edited embryos. Genetic testing can detect issues, but may fall short with mosaic embryos, necessitating more comprehensive approaches to ensure accurate results.
While recent findings are encouraging, regulators continue to demand solutions to mitigate the mosaicism issue before considering the safety of germline gene editing.
Potential strategies include utilizing gene-edited sperm or eggs, where modifications made prior to fertilization could eliminate mosaicism. Although applications in humans are still pending, innovations such as lab-generated sperm from stem cells could pave the way for safe genetic modifications.
Such advances could eventually lead to safe gene editing in future generations, but ethical questions about the implications of gene editing remain unresolved.
In a striking 2021 Super Bowl advertisement, actor Matt Damon declares, “Fortune favors the brave” while showcasing humanity’s remarkable achievements. Flashes of crypto.com appear, subtly implying that anyone can accomplish something monumental. For Ben McKenzie, this was the pivotal moment of realization.
In his thought-provoking documentary, Everyone Is Lying to You for Money, McKenzie reveals his genuine shock while watching this ad on TV. His personal journey—from actor with an economics degree to a critical voice against cryptocurrency wrongdoings—is both enlightening and entertaining. McKenzie captures his audience with a charming, self-deprecating humor, sharing his astonishment at the survival of the biggest players in the crypto scandals over the years.
The film chronicles the evolution of cryptocurrencies, tying it to the erosion of trust that followed the 2008 financial crisis. McKenzie rigorously explores what looks increasingly like a grand scam, targeting fraudulent billionaires heading crypto exchanges and interviewing major players in the gaming industry. Notably, he addresses legal consequences, including Alexander Mashinsky, ex-CEO of now-defunct platform Celsius, and Sam Bankman-Fried, founder of the imploded crypto exchange FTX, both of whom have raised significant alarms within the industry.
Moreover, he casts a critical eye on Hollywood elites jumping onto the ambiguous crypto bandwagon and empathizes with everyday investors who still cling to the belief that cryptocurrency represents the future of finance, despite severe losses.
“Cryptocurrency is not the future of money; it is its past, and engaging with it could be perilous,” McKenzie asserted during a Q&A session post-screening, a sentiment echoed throughout the film. He argues that scams have plagued monetary systems since their inception. Furthermore, he points out the linguistic deception, referring to “selling an idea”; alleging that so-called stablecoins lack true stability and asserting that these digital currencies are not even genuinely decentralized—they lack regulatory oversight. “There are no assets here, only lines of code,” he states emphatically.
McKenzie’s contempt for the deceit surrounding cryptocurrency shines through in both the film and his real-life engagements. Unafraid to address fellow actors endorsing cryptocurrencies, he humorously notes how Matt Damon garners undue attention. When asked about Damon’s reception of the film, McKenzie quipped, “I haven’t heard from him, but I spotted him in Brooklyn once,” while playfully imitating a shy bow. “Sorry, Matt,” he laughed, confidently implying that Damon will navigate the scrutiny just fine.
Everyone Is Lying to You for Money is set for a limited release in the US, with plans for a UK release later this year.

Chimeric mice with rat chromosomes
University of Yamanashi
Colossal Biosciences, a now-defunct company, may be on the verge of revival. Scientists successfully transplanted rat chromosomes, preserved for over a year, into living mouse cells, paving the way for potential reconstruction of mammoth chromosomes within living cells. They crafted a complete mouse embedded with rat chromosomes in specific cells.
“Once we refine the technology, we will begin testing on elephant cells,” stated Teruhiko Wakayama from Yamanashi University in Japan. “If we can introduce elephant chromosomes into mouse embryonic stem cells, we would be eager to proceed with mammoth chromosomes as well.”
<p>The immediate objective of this research is to explore gene activity from extinct animals in contemporary species, potentially revealing insights beyond mere gene sequence analysis. This study also holds implications for conservation and de-extinction initiatives. For instance, in 2004, we preserved tissue from the Hawaiian pouri, an extinct bird. The unique characteristics of biological systems suggest that chromosome transfer is crucial for reviving this species.</p>
<p>An animal's genome is organized into structures known as chromosomes. During cell division, these extensive DNA strands tightly coil into the classic cylindrical shapes depicted in textbooks. These "condensed chromosomes" can be visually identified in living cells by employing dyes that bind to the surrounding proteins, enabling non-invasive observation.</p>
<p>Wakayama's method involves extracting a cell's nucleus and injecting it into an egg cell, initiating chromosome condensation—a process akin to nuclear transfer techniques utilized in cloning. This technique was first applied by Wakayama for cloning a mouse shortly after the birth of Dolly the sheep.</p>
<section>
<!-- Further content and sections can be added here -->
</section>
<p>Upon injection of the nucleus, the egg is treated with enzymes to assist in chromosome separation. A single chromosome is then retrieved using a minute hollow needle and introduced into another egg. As this egg develops into an embryo, the chromosomes subsequently integrate within all embryonic stem cells.</p>
<p>After honing this technique with mouse chromosomes, Wakayama extended the research to rats genetically modified for green fluorescence. Blood cells extracted from the tail of one such rat, preserved for over a year, successfully generated mouse embryonic stem cells containing additional chromosomes from the genetically altered rat.</p>
<p>These cells were then introduced into standard mouse embryos and implanted into female mice, resulting in chimeric animals with rat chromosomes in some of their cells. These mice appear normal but fluoresce green under UV light, indicative of the original rat cells.</p>
<p>The research team aims to create mice with an additional rat chromosome in every cell, but this objective remains unachieved. Currently, the technique appears effective only for chromosome 9 in rats, as attempts to add other chromosomes hinder embryo development. "We are actively exploring various methods to enhance the success rate," noted Wakayama.</p>

<p>The observed interference in embryonic development may stem from activity elsewhere in the rat chromosomes. If this is the case, researchers might need to deactivate genes on supplementary chromosomes, similar to how one X chromosome is inactivated in female mammalian cells. However, Wakayama remains optimistic that this won't be necessary.</p>
<p>The team has acquired samples of frozen elephant tissue from the zoo for experimental purposes. They are collaborating with a team that <a href="https://doi.org/10.1038/s41598-019-40546-1">successfully extracted and studied cell nuclei</a> and are considering using mammoth chromosomes from a 28,000-year-old specimen named Yuka.</p>
<p>Cloning efforts to revive mammoths from these cells are unlikely to succeed due to extensive DNA damage. Nonetheless, Professor Wakayama believes recovery of individual chromosomes for study in living cells is within reach.</p>
<p>“Even a single successful transfer is a significant milestone,” remarked <a href="https://reviverestore.org/about-us/#Ben_Novak">Ben Novak</a>, of Revive & Restore, a conservation organization. "This research could have pivotal implications for passerine birds," a diverse group that encompasses over half of all bird species, where body tissue cells such as skin and muscle no longer carry complete chromosomal information. Reproductive cells, however, retain an extra chromosome essential for survival.</p>
<p>The Hawaiian puli is a passerine bird with only sterile male tissue frozen, necessitating the introduction of two chromosomes from a closely related species—one chromosome from reproductive cells and a W chromosome specific to female birds. "Though this would lead to partial hybrids, it could facilitate the revival of the species," Novak explained.</p>
<p>Wakayama's research is not unprecedented; in 2022, a Japanese team managed to <a href="https://doi.org/10.1016/j.ajhg.2021.12.015">create a rat with an additional human chromosome 21</a> to study Down syndrome. However, this method involves significant genetic modification, making it less applicable for conservation efforts.</p>
<p>The prevalence of extra reproductive chromosomes might be more common than currently recognized, according to Novak, suggesting much of the tissue being preserved by biobanks may be incomplete.</p>

Bite-sized viral comics highlight that open-source software is built on a precarious foundation of multiple components. A cartoon illustrates this with teetering boxes labeled “All Modern Digital Infrastructure,” with a single box at the base maintained by a random volunteer from Nebraska since 2003.
This portrays the reality of open-source software: all websites, applications, and operating systems depend on it. Modern civilization relies heavily on open-source contributions, which are often carried out by dedicated volunteers during their spare time. However, an influx of AI-generated code poses a serious threat to the sustainability of open-source projects, as many contributors experience burnout and exit the community.
AI models have simplified the generation of code for new features, bug fixes, and even entire projects with a mere button click. However, this code is frequently difficult to integrate, confusing, or outright faulty. While submitting code has become easier, the human reviewers tasked with scrutinizing and approving it are increasingly overwhelmed.
In light of these challenges, I arranged an interview with Chad Whitacre, head of the open-source team at Sentry, a multi-billion-dollar company. However, he canceled just days before announcing his resignation, shuttering his LinkedIn and Bluesky accounts and bouncing emails to his inbox. In a blog post, he reflected on retreating from technology to embrace a “neo-Amish” lifestyle, stating that “AI was the last straw.”
In 2025, GitHub—home to numerous open-source projects—logged a staggering 1 billion new code submissions, with projections for over $14 billion in revenue this year, as mentioned by the company’s COO Kyle Daigle in April.
To mitigate the impact of AI-generated submissions, many projects now restrict new contributors from submitting code. Such AI-generated contributions are often made by novice developers seeking to enhance their GitHub submission records for attractive job prospects. The Zig Software Foundation, which advocates for the Zig programming language, has even instituted a ban on AI-assisted submissions, citing their poor quality.
“At first glance, AI-written code may appear functional and devoid of issues, but deeper concerns often linger. Identifying potential malfunctions requires extensive scrutiny,” says Miranda Heath from the University of Edinburgh.
Heath’s research aims to combat burnout among developers to maintain the viability of open-source projects. Yet, many contributors report feeling overwhelmed.
“When individuals experience burnout, they often seek a return to nature, much like how others engage in woodworking or birdwatching,” Heath explains. “Such experiences can strain personal relationships, leading to isolation and exacerbating burnout.”
Heath advocates for government investments in open-source initiatives rather than funneling contracts to wealthy tech corporations. “Instead of dumping funds into high-profile projects, we should reinforce essential resources. [AI] is a bubble,” she asserts.
Vlad Stefan Halbuz also contributes to open source in his spare time at the University of Edinburgh and has directly witnessed user pressures on developers. “Users don’t have the right to impose their demands without acknowledging developers’ mental health,” Halbuz points out.
Halbuz attributes the surge in AI-generated submissions to the companies producing these models, with GitHub being a primary offender. The Microsoft-owned platform has launched its own AI model, Copilot, designed to facilitate code contributions through AI assistance.
“GitHub seems to acknowledge the problems caused by [AI] agents, yet they’re among the primary contributors to this issue,” criticism from Halbuz reveals, though GitHub has not responded to requests for comment on this matter.
The challenge with AI-generated code extends beyond technical failures; significant changes can be made to projects without consulting the development team, jeopardizing project goals and disrupting collaborative efforts—ultimately eroding the open-source community’s core principles.
Mike McQuaid, a developer known for his work on Homebrew, a widely used package manager with approximately 20 million users, has strong opinions on how to navigate these issues.
He initiated Open Source Resistance, a program encouraging team members to allocate work hours toward contributions, noting that approximately 95% of open-source work occurs during business hours.
Furthermore, he isn’t hesitant to block disruptive users, including those who threaten team members, and he rejects substandard submissions—whether AI-generated or not.
“We once experienced a brief golden age in which reports of vulnerabilities were generally credible. However, my recent experiences show that most reports now are AI-generated nonsense, and the skill required has shifted to filtering out irrelevant submissions while conserving time and energy,” McQuaid states.
Yet, in the ever-evolving landscape of AI, implementing bans carries its own unique set of challenges. Open source developer Scott Shambaugh has removed AI-generated submissions from Matplotlib, a widely-used library with approximately 130 million users. Following this, an unidentified AI agent published a hit piece targeting him, accusing Shambaugh of trying to ‘protect his little fiefdom.’
During the winter of 2013-2014, shifts in the jet stream led to the emergence of a significant warm water mass dubbed the “blob,” which extended over 1,500 kilometers across the North Pacific Ocean. This phenomenon was detected by floating instruments anchored to the ocean floor off the coastlines of Alaska, Washington, and Oregon, alerting scientists and the fishing industry to water temperatures exceeding normal levels by up to 4 degrees Celsius.
These instruments are part of the Ocean Observing Initiative (OOI), which comprised five moorings along the West coast of the United States, as well as off the East coast and in Greenland. The National Science Foundation (NSF) announced a substantial $220 million investment in 2023, emphasizing the necessity of the OOI for monitoring “Earth’s vital organs.” However, recent announcements from the NSF indicated plans to dismantle most of these arrays due to funding reductions initiated by the previous administration.
Between 2015 and 2016, sensors attached to the OOI mooring wire identified the warm water mass, with temperatures rising significantly influenced by global-warming events, particularly El Niño. This data revealed that occurrences of the blob happened again in 2019 and may be becoming more frequent due to climate change, which has been associated with toxic algae blooms affecting fisheries, such as the $60 million loss from California’s Dungeness crab fishery.
The removal of OOI moorings jeopardizes not only weather forecasts, including precipitation predictions which affect drought conditions in the western U.S., but also the ability to monitor key elements like the Atlantic Meridional Circulation (AMOC), crucial for maintaining Europe’s temperate climate and assessing El Niño impacts.
“We’re flying blind, which ultimately results in greater costs,” states John Abraham from the University of St. Thomas in Minnesota. Operating the OOI costs approximately $56 million annually, while U.S. commercial fisheries, relying heavily on OOI data, generate billions of dollars annually. Weather-related disasters have historically caused damages reaching $183 billion, further emphasizing the importance of accurate data.
Without access to the OOI data, fishing fleets will struggle to determine which areas will be less affected by El Niño events. This upcoming El Niño is predicted by some models to be among the strongest on record. Oyster, clam, and shellfish farms would find it challenging to prepare for diminished temperatures and nutrients caused by El Niño, while scientists would lose sight of significant impacts on marine ecosystems, including the formation of low-oxygen “dead zones.”
“The timing couldn’t be worse,” lamented Hilary Palewski from Boston University, stressing the critical function of OOI in marine research.
Satellites cannot penetrate the ocean’s surface, making data from submerged floats, gliders, and tethered vessels vital for understanding the Earth’s ocean-covered regions, which account for about 70%. These instruments primarily measure temperature, salinity, and flow, but the OOI moorings also assess pH, oxygen, and CO2 levels—essential for comprehending oceanic biology and chemistry, particularly in remote, monitored regions where water mass movements influence climate.
The loss of these sensor networks will also pose challenges globally, especially concerning AMOC observability. The OOI array located in the Irminger Sea, east of Greenland, is part of the OSNAP initiative—a network of gliders and moorings stretching from Canada to Scotland, monitoring the warm saltwater flow, pivotal for the AMOC. A breakdown in this system could result in Europe experiencing severe winter conditions and disrupt essential monsoon rains vital for agriculture in Africa and Asia.
“OSNAP has revealed that most actual capsize events occur east of Greenland, making the Irminger Sea crucial for understanding variability,” notes Femke de Jong from the Royal Netherlands Marine Institute.
Palewski added that dismantling OOI will leave a significant data gap that could hinder future understanding of the AMOC, even if replacement is pursued later.
Scientists are concerned that the dismantling of OOI may herald a drastic reduction in U.S. ocean research funding, risking initiatives like OSNAP and potentially jeopardizing the Argo project, which comprises around 4,000 drifting instrument floats, over half of which are managed by the U.S.
In a statement to New Scientist, the NSF mentioned that the OOI’s removal is aimed at “prioritizing support for evolving scientific priorities.” However, this is contingent on political agendas, with experts like Gretchen Goldman of the Union of Concerned Scientists condemning it as an “attack on science,” amid proposals to cut thousands of research grants and reduce the NSF budget significantly.
This week, new regulations proposed by the administration seek to eliminate peer reviews for research funding applications and empower political appointees rather than independent experts to determine the fate of federally funded studies. Additionally, bans on international cooperation and studies on gender and diversity are planned.
Edward Deaver, a professor at Oregon State University managing the OOI array, emphasizes that both the dismantling of OOI and the proposed grant rule changes constitute sweeping reforms that threaten to undermine peer review and politicize NSF-funded research.
A recent study indicated that dismantling even a fraction of the Global Ocean Observing System, which includes the OOI and Argo floats, could inflate errors in annual ocean heating rates by 33%. This is akin to predicting an unemployment rate of 3% with an imprecise range of 2% to 4%, according to Abraham, a member of the research team.
“This is a calculated move to silence our monitoring of the ocean,” he asserts regarding the OOI dismantling. “If we don’t measure, how can we identify problems?”
A nearly complete bovine skeleton discovered at the early Pliocene site of Camp dels Ninotz in northeastern Spain has unveiled that the ancestors of modern buffaloes and cows had reached impressive sizes long before humans inhabited the continent.

“Cows play a vital role in many contemporary ecosystems and human agriculture, particularly species within the Bovini tribe, such as bison, buffalo, and cattle,” stated Dr. Leonardo Solberg from the Leibniz Institute for Evolutionary and Biodiversity Sciences and his colleagues.
“However, due to the scarcity of well-preserved early fossils, their evolutionary origins and relationships with close relatives remain largely unknown.”
The study involved the examination of at least 14 human remains excavated from the Camp dels Ninotz site in Spain.
Researchers identified the specimen as Parabos tineresi, one of five buffalo-like species that thrived in Europe during the early Pliocene.
The largest of these animals is estimated to have weighed nearly 500 kg, making it smaller than most existing bovine species but larger than other similar bovid species of the period.
This indicates an early stage of body size increase in the bovine lineage, possibly as an adaptation to the changing climate and environment that characterized continental Europe during the Pliocene.
Their anatomy suggests a preference for moist, plant-rich environments, aligning with researchers’ understanding of the water-abundant ecosystem at the Camp dels Ninotz site.
Researchers argue that the early Pliocene marked the dawn of large cattle, but the exact evolutionary connection between cattle and cows remains unclear. The status of Parabos also remains ambiguous.
Comparative studies suggest that Parabos could either represent early members of the Bovini tribe or more modern relatives of the related Tragoportacini lineage, which was eventually supplanted by true water buffalo, cattle, and bison.
Future research focusing on the anatomy and ecology of Parabos will clarify their place in the bovine evolutionary narrative.
“The Camp dels Ninotz bovid is one of the most exquisite fossils from the European Pliocene,” remarked the researchers.
“The exceptional preservation of these specimens allows for a deeper understanding of their anatomy and, consequently, the ecology of the continent’s earliest large bovids.”
“Studying these fossils presented both challenges and rewards.”
“The extraordinary preservation and richness of the findings have provided us an unprecedented wealth of data for this ancient geological period, offering a new perspective on the world before humans.”
The study has been published in the journal PLoS ONE.

A supermassive black hole, boasting six billion times the mass of our Sun, resides in MRG-M0138. This discovery is based on data from the NIRSpec Integral Field Spectrometer on board NASA/ESA/CSA’s James Webb Space Telescope. MRG-M0138, a quiescent galaxy influenced by gravitational lensing, was observed when the universe was a mere 3 billion years old.
This image showcases the highly distorted red galaxy MRG-M0138 as viewed through the foreground galaxy cluster. Image credit: NASA / ESA / CSA / Webb.
Located over 10 billion light-years away, MRG-M0138’s appearance is magnified by a massive galaxy cluster, making distant galaxies seem around 30 times larger than they would normally appear.
Currently, MRG-M0138 is not forming stars, and its central black hole is also inactive.
“Utilizing Webb’s remarkable vision combined with the effects of gravitational lensing, we successfully detected this black hole located 10 billion light-years away,” remarked Dr. Andrew Newman, an astronomer at the Carnegie Institution for Science and the University of Southern California.
Dr. Newman and his team studied MRG-M0138 using Webb’s NIRSpec Integrating Magnetic Field Spectrometer.
“By merging Webb’s data with gravitational lensing effects, we were able to observe within the influence sphere of a black hole, where gravity accelerates star speeds,” he added.
“This method is one of our most effective for measuring black hole masses, and we are thrilled to apply it to earlier epochs in the universe’s timeline.”
“Only a handful of dormant black holes of this size have been detected, all in nearby regions.”
This groundbreaking finding sheds new light on the co-evolution of black holes and galaxies in the early universe.
Observations of nearby galaxies show a close correlation between the mass of central black holes and the characteristics of surrounding galaxies.
However, it has been challenging to determine if such relationships existed billions of years ago.
This fresh discovery hints that the densest galaxies were often sites for rapid black hole growth early in the universe’s history.
Though currently dormant, it is believed that MRG-M0138 was once a powerful quasar.
Professor Richard Ellis from University College London noted, “By analyzing how stars move collectively within this distant galaxy, we can measure the mass of a supermassive black hole that would otherwise remain undetectable.”
“Proving the viability of these methods for early universe galaxies will enable a more thorough investigation of black hole development over time and illuminate their role in galaxy evolution.”
The full results are published in the journal Sciencehere.

The tree-like form arises from the connections within the Collatz conjecture.
Marzio de Biagi/Algolito Malte
Nearly a century ago, the renowned mathematician Lothar Collatz introduced a deceptively simple yet profoundly challenging puzzle. This problem has captivated numerous mathematicians, generating much discourse and debate. Despite many claiming to have solved it, the quest for a comprehensive proof continues. Once you grasp the rules, you might find yourself enraptured, and I take no responsibility for any hours you might lose to this intriguing riddle.
The process begins like a magic trick: choose any positive integer. If the number is even, divide it by 2. If it’s odd, multiply by 3 and add 1. Apply these rules iteratively to the resulting numbers. Mathematicians believe that eventually, this process will always lead to 1.
This question, known as the Collatz conjecture, remains unresolved for all positive integers. The conjecture, initiated by Lothar Collatz in the 1930s, has proven to be remarkably challenging. Even the esteemed mathematician Paul Erdős remarked, “mathematics may not be ready for such problems.”
So, what makes the Collatz conjecture so perplexing to prove? Upon hearing about this problem, many rush to calculators, eager to verify if various numbers reach 1. In fact, comprehensive computer algorithms have checked all numbers up to 271, but given the infinity of integers, finding a definitive proof remains elusive.
The behavior of these numbers is unpredictable. Starting with 1 leads to conclusive results, while initiating with 2 accomplishes the same. However, beginning with 3 generates a chain: 10, 5, 16, 8, 4, 2, and finally 1. For 7, the sequence is more extensive, containing intermediate steps that eventually lead back to previously evaluated numbers. This implies that once you revisit past numbers, there’s no need to recalculate since their paths are already known.
This chaotic nature poses significant challenges for mathematicians. I recall a quote from the xkcd webcomic: “There’s a certain type of brain that easily malfunctions when presented with an intriguing problem.” Indeed, as the Collatz meme spread, countless individuals became ensnared by its allure.
The consequences of Collatz’s conjecture affect many enthusiasts.

The Mysteries of the Collatz Conjecture Unveiled
Tracing the origins of the Collatz conjecture is surprisingly challenging, yet obtaining a proof remains an even greater endeavor. In a 1980 correspondence, Collatz mentioned his long-standing investigation. Initially, he seemed to view this problem as merely a mathematical curiosity. The conjecture began gaining traction around 1950 during the International Congress of Mathematicians conference, where discussions among peers brought it into the spotlight.
Following its rise in popularity, the problem was rediscovered by various mathematicians, acquiring names like the Syracuse problem, Hasse’s algorithm, and the 3x+1 problem. This topic first appeared in print in 1971, described as “mathematical gossip.” It gained wider recognition when Martin Gardner featured it in a 1972 issue of Scientific American. Gardner, a prominent figure in recreational mathematics, fueled public intrigue in this enigmatic problem.
The Collatz conjecture has consistently straddled the line between recreational and formal mathematics. An article from 1983 titled “Do Not Try to Solve These Problems” warned mathematicians against tackling the conjecture, understanding that the temptation was almost irresistible.
Lothar Collatz dedicated over 50 years to analyzing his conjecture.

A notable advancement came in 1976, when Riho Terrace demonstrated significant results. When starting with an even number, the first operation halves it, ensuring that the Collatz chain remains below this initial number. Conversely, starting with an odd number means the first step goes above the starting point. This concept introduced the “stop time” of numbers, confirming that, in most instances, the numbers will decline rather than diverge indefinitely.
Nevertheless, this isn’t sufficient to validate the Collatz conjecture. A solitary enormous counterexample that fails to converge to 1 would invalidate the conjecture. Moreover, tackling infinite potentials raises questions about the meaning of “almost all.” In 2002, Ilya Krasikov and Lagarias provided a proof indicating that for a given number x, at least x0.84 of integers less than x ultimately arrive at 1. For instance, if x is 100, it implies at least 47 integers below 100 do reach 1.
The most significant breakthrough emerged in 2019, when Terence Tao, perhaps the preeminent mathematician of our era, accepted the Collatz challenge. He established a stronger version of Terras’ findings, suggesting that “almost all” numbers not only drop below their initial value but can be reduced to any desired lower threshold. While this progress feels near proof, the existence of potential counterexamples continues to loom.
What lies ahead for the Collatz conjecture? As I compose this piece, reports emerge that OpenAI utilized large-scale language models to tackle a major mathematical conundrum that has confounded scholars for approximately 80 years. Not through a straightforward proof, however, but via the discovery of unexpected counterexamples. Could AI potentially solve the Collatz conjecture? While predictions are premature, it would be intriguing if a challenge that has vexed the human intellect were ultimately resolved by artificial intelligence.
Paleontologists have recently confirmed that Praacturus gigas is the largest scorpion ever discovered, having roamed the shallow seas during the Devonian period, approximately 415 million years ago.

This ancient creature measured approximately 1 meter (3.3 ft) long and boasted formidable pincers over 16 centimeters (6.3 inches) in length. According to Praacturus gigas, it was a powerful predator that thrived in floodplain ecosystems during its time.
Originally identified as an isopod in 1871, Praacturus gigas was later reclassified after comparisons with various arthropod groups and featured in a limited edition illustration of a giant scorpion from the 1980s.
Lead author Dr. Richard Howard, curator of fossil arthropods at the Natural History Museum in London, stated, “When people think of giant arthropods, they often envision the Carboniferous rainforests of Earth’s late history, where massive insects like millipedes and dragonflies thrived.”
However, Praacturus gigas existed at least 50 million years prior to that era, in a time when large terrestrial life was just beginning to take shape.
“Confirming that this creature is indeed a scorpion significantly alters our understanding of the evolution and growth of these astonishing animals,” added Dr. Howard.
In a groundbreaking study, Dr. Howard and his team employed modern analytical methods and fossil comparisons, concluding that Praacturus gigas is accurately classified as a scorpion.
Co-author Dr. Russell Garwood, a paleontologist at the University of Manchester, commented, “Praacturus gigas has baffled paleontologists for over a century. Our collaboration, utilizing advanced imaging techniques, has allowed us to construct a much clearer understanding of these ancient creatures.”
“What’s particularly intriguing about Praacturus gigas is its significant size during an epoch when most life forms on land were quite small. This suggests an ecosystem capable of supporting giant predators,” he added.
To gain insights into this ancient ecosystem, the research team compared scorpion fossils with other contemporaneous fauna.
The findings indicate that Praacturus gigas likely inhabited aquatic environments, where larger life forms were more prevalent.
During the early Devonian period, complex terrestrial ecosystems were in their infancy; only simple plants and fungi had begun to populate the land.
This means that, unlike later megafauna, this giant scorpion did not benefit from the elevated oxygen levels found in more advanced forested environments.
Instead, its large size may have been a result of limited competition from other sizable predators.
Fossil evidence also suggests that Praacturus gigas may have had a semi-aquatic lifestyle.
Co-author Dr. Greg Edgecombe, also a paleontologist at the Natural History Museum in London, remarked, “Back then, the distinction between land and sea was far less defined. Praacturus gigas gives us a fascinating glimpse into how early animals adapted to these shifting environments.”
“This species may even represent a lineage that returned to aquatic life after its ancestors had already commenced living on land,” he noted.
The team’s paper was published in the latest issue of Paleontology.

Recent research conducted by archaeologists at Curtin University and Sheffield Hallam University indicates that Neolithic communities, rather than glaciers, were responsible for transporting Stonehenge’s iconic six-tonne sandstone Altar Stone from north-eastern Scotland to Salisbury Plain.

Curtin University researcher Dr. Anthony Clarke stated, “Our findings indicate that transporting the Altar Stone involved meticulous planning over multiple stages.”
“Instead of being carried naturally by ice, our evidence points to a calculated movement across various challenging terrains.”
“Our simulations suggest that during the last Ice Age, while glaciers might have transported rocks to Dogger Bank in the North Sea, they did not reach southern England. Therefore, prehistoric people had to move the stones hundreds of kilometers manually.”
“This study reveals no feasible glacier route connecting the source area to Stonehenge, thus confirming the necessity of human transport.”
“This implies that the stones may have been transported in stages, potentially utilizing a combination of land and water transport methods.”
The research incorporated mineral dating, geological provenance analysis, and computer simulations of ancient ice sheet movements to understand how the Altar Stones came to rest on Salisbury Plain.
The team initially identified the stone source in north-eastern Scotland by analyzing its mineral composition and age.
They then modeled the behavior of ancient glaciers and found evidence suggesting that the ice may have carried the stones southeast to Dogger Bank, currently submerged in the North Sea.
From these findings, the research team proposed that prehistoric peoples may have retrieved the stone from Dogger Bank, transported it to Salisbury Plain, and ultimately integrated it into the construction of Stonehenge.
“This discovery highlights an impressive level of organization and collaboration among Neolithic communities,” Dr. Clarke remarked.
“Transporting large stones over extensive distances would have required intricate planning, coordination, and a profound understanding of the landscape, along with significant determination.”
“Our study demonstrates the effectiveness of combining geological analysis and computer modeling to address enduring questions about the construction of Stonehenge.”
“Future research intends to pinpoint the exact origin of the Altar Stone in north-eastern Scotland and further explore potential transport routes utilized by prehistoric peoples.”
The results will be published in today’s Quaternary Science Journal.

Jiang Changmensis is the pioneering non-avian dinosaur discovered at a paleontological site featuring over 100 early Cretaceous bird specimens.
Jiang Changmensis (Left) launched an early attack on Gansus yumenensis (Right) in the Changma Basin, now in northwestern China, around 120 million years ago. Image credit: Lewis LaRosa / Jão Canola.
Jiang Changmensis roamed what is now northwestern China approximately 124 to 120 million years ago during the Early Cretaceous period.
Members of this lineage include the Microraptor, a four-winged dinosaur believed to be capable of gliding and possibly powered flight.
Dr. Jingmai O’Connor, a paleontologist at the Field Museum of Natural History and the Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, stated, “Jiang Changmensis is one of the largest Microraptor specimens ever discovered.”
“The humerus bone fragment we possess measures approximately 10 centimeters (4 inches) in length, suggesting the dinosaur likely had a wingspan of about 4 feet, roughly the size of a barn owl.”
“We believe Jiang Changmensis, like other Microraptors, had long feathers on both its arms and legs, giving it four ‘wings’ for gliding.” Dr. O’Connor added that, while other Microraptors were likely unable to achieve true powered flight, they could probably glide like flying squirrels.
The skeletal remains of Jiang Changmensis were found in the Xiagou Formation, uncovered near Changma Village in the Changma Basin, Gansu Province, northwestern China.
This site yielded over 100 early Cretaceous bird skeletons, many of which preserved soft tissues such as feathers and skin. However, until now, no non-avian dinosaur specimens had been recorded from this location.
Dr. O’Connor remarked, “Scientists had uncovered strange clusters of dismembered bird bones at this site, but we lacked an understanding of what had caused them.”
“Now, with the discovery of Jiang Changmensis, we have our best hypothesis.”
“This is the only dinosaur found at this site that isn’t a bird, and it was considerably larger than the other dinosaurs discovered there.”
The discovery of Jiang Changmensis holds greater implications beyond identifying a new species.
Previously, all distinct members of the Microraptorinae subfamily were found in the Jehor Group, a series of geological formations located approximately 2,000 km from Changma, extending confirmed ranges into northwestern China.
Dr. Matt Lamanna, a paleontologist at the Carnegie Museum of Natural History, emphasized, “Jiang Changmensis demonstrates that non-avian dinosaurs inhabited the current Chanma Basin, renowned for its bird fossils.”
“Our team has recovered over 100 bird fossils in Chanma, but this is the sole non-avian dinosaur specimen.”
Jiang Changmensis offers critical new insights into the biological history of the Changma region and the ecological context of today’s bird ancestors.
“Understanding life on Earth today necessitates examining its origins.”
“Birds are arguably the most successful group of terrestrial vertebrates on the planet today.”
“By exploring early birds and their non-avian dinosaur relatives, we gain a clearer understanding of why this avian group has persevered.”

Brown rot, a prevalent fungal disease in the southeastern United States, significantly impacts stone fruits like peaches, cherries, and plums.
Monilinia fructicola
is a fuzzy yellow-brown fungus that thrives on the flowers, twigs, and fruits of these trees, being the primary culprit behind brown rot. Once a tree is infected with brown rot, the damage is irreversible, leading to considerable crop losses in commercial orchards. Farmers are actively working to mitigate the spread of this infectious disease
M. fructicola
by applying a chemical spray known as
fungicide during the spring months.
In
M. fructicola
, a biosynthetic gene called
MfCYP51
encodes a vital protein essential for fungal survival. Certain fungicides categorized as
Demethylation Inhibitors
(DMI) aim to disrupt this protein’s function, but over the past two decades, DMI fungicides have shown decreasing efficacy against brown rot, with
M. fructicola developing increased resistance.
Live microorganisms and their metabolites present a promising alternative to traditional chemical fungicides.
Biological disinfectants
can contain bacteria that produce harmful compounds like hydrogen cyanide and pyrrolnitrin, which are detrimental to fungal cells. However, a commercially viable biofungicide has yet to be identified. A research team from Clemson University in the US and Huazhong Agricultural University in China has initiated tests to evaluate the efficacy of soil bacteria
Pseudomonas chlororaphis and
Bacillus subtilis
in combatting brown rot.
The researchers conducted culture experiments to analyze how fungal cells express the key protein
MfCYP51
under various fungicide treatments. They investigated three strains of
M. fructicola
susceptible to conventional DMI fungicides, alongside three resistant strains, utilizing five different treatment variations, including DMI fungicide,
P. chlororaphis
metabolites, a combination of
Bacillus subtilis
cells, and their respective combinations with DMI fungicides. A control group using sterilized water instead of a disinfectant was also established.
After six hours, the researchers extracted RNA molecules from the fungi to measure gene expression. Treatments with
P. chlororaphis
and DMI fungicide +
P. chlororaphis
led to a significant decrease in
MfCYP51
expression in both susceptible and resistant isolates when compared to controls. In contrast, DMI fungicides combined with
Bacillus subtilis
increased
MfCYP51
expression in resistant isolates. The researchers concluded that
P. chlororaphis
possesses a unique capability to reduce gene expression compared to other biofungicides.
To further explore how biofungicide treatments operate, the team investigated how
P. chlororaphis
and
Bacillus subtilis
produce the antifungal metabolite pyrrolnitrin. They analyzed treatment solutions using a high-performance liquid chromatograph to separate and identify the liquid compounds. Their findings suggested that pyrrolnitrin was potentially involved in reducing gene expression.
Additionally, the researchers performed five treatments on Gala apples to assess brown rot. Each apple underwent surface cleaning and disinfection, followed by fungicide application. After 24 hours, they punctured the apples and added 20 microliters of
M. fructicola
cells, then placed them in a humid environment for five days to evaluate the brown rot spots.
Despite the reduced
MfCYP51
expression observed, treatment with
P. chlororaphis
alone did not lower brown rot incidents compared to the control. However, treatments with DMI fungicide and
Bacillus subtilis
effectively reduced brown rot spots. Specifically, the DMI fungicide +
P. chlororaphis
treatment significantly prevented brown rot compared to the control.
The researchers concluded that while biofungicides may lack standalone efficacy, their application could help farmers minimize reliance on DMI fungicides. By reducing DMI fungicide usage, infection rates of
M. fructicola
resistance could be slowed. They propose future studies to test biofungicide mixtures containing pyrrolnitrin in real-world settings on stone fruit trees.

How did Matt Freeze excel in his journey? He steadily advanced through college and professional soccer, dedicating the same enthusiasm a child would show when jumping into bed. “I keep reminding myself,” Freeze shared with NBC News, “I’m always a student of the game.”
The ethos of being a lifelong learner runs in Matt’s family. His paternal grandparents, Ernst and Elizabeth Freese, were exceptional German scientists who immigrated to the USA after World War II. They contributed their talents to the National Institutes of Health, with Ernst being a renowned molecular biologist known for his groundbreaking studies on DNA mutations, cancer, Parkinson’s, and Alzheimer’s diseases.
“He uncovered the mechanics of genetic mutations,” stated Katherine Freese, Matt’s aunt. “This is foundational to our understanding of evolution.”
Catherine, another remarkable figure in the family, is an astrophysicist at the University of Texas, specializing in dark matter research. She tackles pivotal questions like: “How did the universe originate?” and “What is the universe composed of?”
Matt’s father, Dr. Andrew Freeze, a Harvard-trained neurosurgeon, profoundly impacted the field of gene therapy. His journey included earning a Ph.D. in neurobiology from MIT. Sadly, he passed away in 2021 at age 61 due to kidney failure.
The family legacy extends to numerous scholars who boast impressive credentials and achievements. “It’s like a family tradition,” Katherine noted.
Consider Matt’s surprise when a high school peer announced his aspirations of becoming a professional soccer player. Andrew, unfamiliar with sports culture, had concerns about his son’s future. “It felt a bit foreign to him,” Matt recalled.
Family reactions were mixed, with one uncle quipping, “Poor Matt will just warm the bench.” This uncle was also a biologist, Catherine added. “Oh, that’ll never work!”
Eventually, Matt and his father reached a compromise. Matt enrolled at Harvard University to study economics and played on the football team for two seasons before signing with MLS’s Philadelphia Union in 2018. The pandemic later allowed him to complete his degree online in 2022, though Andrew never witnessed his graduation.
“He’s undoubtedly proud,” Katherine stated. “Matt surpassed all expectations.”
Matt applied his academic insights during university, conducting a comprehensive research project focused on penalty kicks. As he progressed in soccer, it became evident that his greatest asset as a goalkeeper lay in his mental approach, handling the position almost scientifically.
“Many people mistakenly believe that goalkeeping is solely about saving shots,” Freeze explained. “Our goal is to prevent them by being aggressive, strategically positioned, and maintaining clear communication, all while reading the game effectively.”
Goalkeepers constantly evaluate the field, identifying threats and positioning themselves to defend against challenges. “A significant part of goalkeeping involves maximizing the area of the goal you can cover,” Freese said.
Fortunately, Freeze possesses a problem-solving intelligence inherited from his father. “He has a logical, analytical mindset,” stated Katherine. “It’s a unique perspective that allows him to synthesize information in ways others can’t.”
What does this perspective entail? “In mathematics and physics, creativity is essential. While equations exist, one must approach problem-solving with an inventive mindset. By combining concepts A and B, one can discover innovative solutions.” This ability is a distinctive skill they share.
Matt believes that despite the key role a goalkeeper plays in a match, their performance is often evaluated based on just a few pivotal moments. “Typically, you only get two or three significant opportunities per game, so it’s crucial to remain fully focused and explosive in those instances.”
To excel in those high-stakes moments, Freeze follows a specific routine. He diligently reviews game footage and studies his opponents but consciously limits his cellphone usage and avoids social media. His diet primarily consists of chicken, vegetables, and carbohydrates during the season. He also practices meditation to align with his body’s natural rhythms and makes a point to soak up sunlight each morning.
Moreover, Matt’s unique biology sets him apart from other goalkeepers. According to his family history, his maternal grandfather, Jack Geary, served as an Air Force pilot and a professional football player. In tribute, Matt wears the number 49 on his jersey for NYC FC. “Natural athleticism played a role,” Freese remarked. “I’m grateful for that, but it has to be expressed. To achieve that, one must flow, remain agile, and execute those critical saves.”

The “Cold Blob” in Temperature Visualization
Credit: NASA Scientific Visualization Studio/Goddard Space Flight Center
The Earth’s surface has experienced warming over the past 150 years, with the exception of certain areas in the North Atlantic Ocean. This specific region, found southeast of Greenland, has been termed the “warming hole” or “cold mass,” indicating it is up to 1°C cooler than historical averages.
There is ongoing debate among scientists regarding the reason for the existence of this cold blob. Recent studies suggest it may be linked to the weakening of the Atlantic Meridional Circulation (AMOC), a crucial ocean current that distributes warmth from the tropics to Europe.
<p>The AMOC is responsible for transporting warm, salty water from the Gulf of Mexico to the North Atlantic, where it cools, sinks, and then returns south along the ocean floor. Scientists are concerned that an influx of freshwater from melting ice in Greenland could lower the salinity in this area, potentially slowing the sinking process and weakening the overall circulation.</p>
<p>Recent research indicates that the AMOC may <a href="https://iopscience.iop.org/article/10.1088/1748-9326/adfa3b">cross a tipping point</a> in the coming decades, potentially leading to a complete collapse. This collapse could have severe consequences, causing significant cooling in Europe and disrupting critical monsoon rains vital for agriculture in Africa and Asia. However, current direct observations of AMOC strength span only 22 years, which is insufficient to establish clear trends.</p>
<p>Climate <a href="https://www.nature.com/articles/s41586-018-0006-5">modeling</a> suggests that the slowing AMOC reduces the supply of warm water to the North Atlantic, thereby creating this cold mass. Other models, however, attribute a major portion of the phenomenon to atmospheric changes.</p>

<p>A <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022GL100420">2022 study</a> by <a href="https://cos.northeastern.edu/people/chengfei-he/">He Chengfei</a> and researchers from Northeastern University, Boston, found that accelerated warming in the Arctic is diminishing the temperature disparity between the polar regions and tropics. This shift is causing the jet stream to move northward into the cold mass area, resulting in stronger westerly winds that increase evaporation, drawing heat away from the ocean.</p>
<p>As evaporation intensifies, cloud cover also increases. Some research indicates that this cloud cover may further contribute to the cooling of the blob.</p>
<p>Research led by <a href="https://www.pik-potsdam.de/members/stefan/homepage">Stefan Rahmstorf</a> at the Potsdam Institute for Climate Impact Research is closely examining the cold mass through climate reanalysis, utilizing direct weather observations from satellites, buoys, and ships, rather than relying on modeling techniques.</p>
<p>Since 1955, they have discovered that heat loss from the ocean’s surface has diminished in the cold mass area. It appears that the ocean is cooling not just at the surface but also at depths of up to 1,000 meters. This indicates that the AMOC is transporting less heat rather than the atmosphere removing more heat.</p>
<p>According to Rahmstorf, “Wind and clouds can only account for a minor portion of the warming hole. While some models suggest atmospheric influences, the data indicates that oceanic factors are the primary causes.”</p>
<p>This finding highlights that the Atlantic circulation has been undergoing changes for decades, intensifying concerns regarding the potential collapse of not only the AMOC but also the surrounding subpolar circulation, which is vital to the process. If this circulation were to shut down, <a href="https://nyaspubs.onlinelibrary.wiley.com/doi/abs/10.1111/nyas.14659">the UK and neighboring regions may experience even more rapid temperature drops</a> than a full AMOC collapse.</p>
<p>Rahmstorf warns, “The subarctic circulation reaching a tipping point could lead to severe climate impacts in Western Europe as early as the 2040s.”</p>
<p>However, direct measurements of ocean surface heat fluxes are currently lacking, making it challenging to accurately estimate them through modeling. A 2021 study, which used data from Rahmstorf's research, found that winds <a href="https://link.springer.com/article/10.1007/s00382-021-06003-4">may account for the majority</a> of the cold blob's formation.</p>
<p>According to He, “Inferring the energy budget of a cold mass using reanalysis poses significant challenges.”</p>
<p>While recent research provides valuable insights, experts like <a href="https://profiles.ucl.ac.uk/38605-david-thornalley">David Thornalley</a> from University College London caution that definitive conclusions about the causes of cold blobs remain elusive.</p>
<p>Limited data prevents us from entirely ruling out alternative explanations. For instance, <a href="https://www.sams.ac.uk/people/researchers/fraser-dr-neil/">Neil Fraser</a> from the Scottish Marine Science Society notes that a tributary of the AMOC, known as the Norwegian Current, may be strengthening and transporting additional heat away from the cold mass regions.</p>
<p>In conclusion, while the existence of the cold mass aligns with AMOC weakening, conclusive evidence remains to be established.</p>

While parenthood can disrupt date nights, not all is lost in love.

Feeling exhausted from caring for a newborn makes it seem like there’s little time for love. New research indicates that couples tend to feel less love for their partners in the first year of parenting. Fortunately, there are steps to rekindle that connection.
Previous studies demonstrate that relationship satisfaction often declines in the two years following childbirth, with pre-pregnancy conditions frequently overlooked. Dr. Agnieszka Sorokowska, a researcher at the University of Wroclaw in Poland, sought to explore these shifts in relationships.
Sorokowska and her team studied approximately 300 childless heterosexual couples, each in committed relationships for at least two years. Participants were surveyed every six months for two years, rating their feelings of love and commitment on a scale from 0 to 6.
After examining the data from 71 couples who welcomed children during the study, researchers found that while pregnancy itself had no adverse effects, there was a noticeable decline in feelings of attachment and commitment within the first year post-birth. Couples who remained childless did not experience similar changes.
At the recent Love, Practical and Theoretical conference in Edinburgh, Sorokowska announced intentions to follow these couples until their children reach adulthood to investigate potential long-term impacts. However, past research indicates that relationship satisfaction generally improves over time, showing a steep decline followed by gradual recovery after the initial years.
Dr. Valentina Rausch-Anderegg, an independent psychologist based in Zurich, affirms that new parents may experience significant distress as a result of these early relationship changes. “Not all couples will need therapy,” she notes, “but many will notice shifts in their interactions.”
Factors such as physical and hormonal changes during pregnancy, along with overwhelming childcare responsibilities, often contribute to this dynamic. “Even simple moments, like watching Netflix or taking walks together, can feel impossible,” Rausch-Anderegg explains.
To mitigate these challenges and rediscover the romance, she encourages couples to reach out to friends and family for support and to openly discuss their concerns. “Clearly communicate your vision for parenting. Identify what aspects of your relationship are essential, even after having children—be it an annual hike or dedicating a weekly 20 minutes to reconnect with your partner.”
A new strain of Lyme disease has emerged in New York State, raising public health concerns.

Most tick-borne diseases in the United States are caused by Borrelia burgdorferi, a corkscrew-shaped bacterium. However, there is another rarer species called Borrelia mayonii, which has thus far only been found in Minnesota and Wisconsin, both spread via deer ticks.
Recent CDC reports indicate that cases of B. mayonii Lyme disease were identified in upstate New York as of last July.
This infection was diagnosed in an adult from Herkimer County, extending from Utica to the Adirondack Mountains, who had not traveled recently.
The state health department found several infected ticks on the person’s property; however, a broader study of over 1,500 ticks across 24 New York counties yielded no bacteria.
The exact origin of the bacteria in Herkimer County remains unclear.
“Although this discovery was unexpected, tick species and tick-borne diseases can fluctuate geographically,” stated a spokesperson from the New York State Department of Health.
Douglas Norris, a molecular microbiology and immunology professor at Johns Hopkins Bloomberg School of Public Health, suspects that the bacterium has been present in New York ticks for several years but remains tightly contained.
Different Symptoms, Same Disease
Research on B. mayonii is limited compared to B. burgdorferi, having been discovered only in 2016 by Mayo Clinic researchers. Both species can lead to severe illness.
Symptoms can start with fever and headache. However, Lyme disease caused by B. mayonii is more likely to result in nausea and vomiting.
Norris noted that individuals infected with this less common species may not develop the rash typically seen around the tick bite. Instead, they may exhibit a rash of small red spots over a broader area.
Dr. Bobby Pruitt of the Mayo Clinic emphasized the potential for a range of neurological symptoms. “Many broader symptoms might still be unrecognized,” he noted.
The health department did not specify the symptoms exhibited by New Yorkers infected with B. mayonii last year.
Rising Lyme Disease Cases
Cases of Lyme disease have been rapidly increasing in New York. From 2020 to 2024, the incidence rose nearly 450%, soaring from about 37 cases per 100,000 people to 165 cases per 100,000. According to Department of Health statistics.
Potential occurrences of B. mayonii may rise across the Northeast, but infections remain rare, according to Pruitt.
Norris adds, “Borrelia burgdorferi will likely remain the predominant cause of Lyme disease in the U.S. and B. mayonii is not primarily responsible for it.”
Even in areas where B. mayonii has been previously documented, like the upper Midwest, cases are few. For instance, out of Minnesota’s roughly 3,000 annual Lyme disease cases, only about 2 are attributed to B. mayonii, according to the Minnesota Department of Health.
A study revealed that only 0.2% of larval ticks in New York carried B. mayonii, while around 1% of adult ticks did. In contrast, approximately 25% of nymphs and 50% of adult ticks are infected with B. burgdorferi in the Northeast.
Timing is crucial, as it takes 24 to 48 hours for ticks to transmit infectious bacteria after attachment. Therefore, the smaller nymphs are typically the responsible vectors for Lyme disease.
“People often see larger ticks, but these smaller ones typically go unnoticed,” Norris explained.
Impact of Climate Change on Lyme Disease
Norris stated that while tick-borne diseases are evolving due to climate change, this is likely not the reason for the emergence of B. mayonii in New York.
“Unfortunately, it was introduced right where it could thrive,” he noted.
Experts speculate that the bacteria may have been transported by infected ticks on migratory birds from Minnesota or Wisconsin.
New York has a climate conducive to tick reproduction and the survival of Lyme disease pathogens, creating a “sweet spot” that is shifting northward due to climate change, resulting in increased Lyme disease cases in areas previously known for their endemic status.
To minimize the risk of tick bites, experts recommend staying in the center of trails during hikes and avoiding tall grass. Wearing long sleeves and tucking pants into socks can provide additional protection. Using a repellent with 30% DEET or lemon eucalyptus oil is also advised. Regular tick checks after outdoor activities are essential, as is showering to remove ticks after being in tick-prone areas.
“We aim to encourage outdoor activities while ensuring people take necessary precautions against tick bites,” experts say. “Ticks can transmit various pathogens and diseases, so awareness is crucial.”
Recent studies reveal that the human brain can learn to multitask effortlessly, often without our awareness.

For years, experts believed that the brain couldn’t handle multiple tasks simultaneously. This was attributed to the prefrontal cortex, a key brain region responsible for logical planning and problem-solving, known for its rigidity.
“We are wired to focus on one task at a time, which is often beneficial,” explained Maximilian Riesenhuber, a neuroscience professor at Georgetown University and lead researcher of the study published in the Journal of Cognitive Neuroscience. “This allows individuals to maintain focus while managing other responsibilities effectively.”
Previous research suggested that when individuals multitask, their overloaded prefrontal cortex swiftly switches between tasks.
Riesenhuber’s experiments demonstrated that the brain uses alternative strategies that develop over time through practice and experience, enabling unconscious task execution and freeing the prefrontal cortex for other duties.
The study involved 11 participants aged 18-29, who spent several weeks using an app to categorize computer-generated car images based on shared characteristics, repeating the process over 30,000 times within 5 to 10 weeks.
Initially, imaging tools indicated high activation in the prefrontal cortex; however, after weeks of task repetition, participants utilized the temporal cortex, a region associated with long-term memory, for categorization.
Riesenhuber noted that the findings suggest the prefrontal cortex can forge connections to relay information to the temporal cortex more effectively.
“This represents a form of automation, liberating the brain’s front regions to engage in additional tasks that require attention,” he stated.
This ability to master multitasking without conscious effort explains several automatic functions in daily life.
Riesenhuber pointed out that while novice drivers must fully concentrate on operating a vehicle, seasoned drivers can engage in conversation or listen to music while driving.
Michael Schoenberg, a licensed psychologist and neurosurgery expert at the University of South Florida, not involved in the study, emphasized that this research sheds light on the development of specialized skills, like analyzing brain scans or performing at Olympic levels in gymnastics.
“I have colleagues proficient in EEG tests, while I struggle to interpret them,” Schoenberg remarked. “In sports, mastering activities like the balance beam demands considerable focus and concentration, but repetitive training fosters muscle memory.”
Riesenhuber believes this principle also applies to essential aspects of childhood development, including learning to recognize objects or names, enabling automatic responses throughout life.
“We don’t examine a tree and ponder if it’s a tree,” he noted. “People aren’t born with knowledge of objects; they learn to inherently associate meaning with their surroundings.”
Variability in brain rewiring capabilities suggests some individuals naturally excel at multitasking. The Georgetown experiment showcased significant differences in how quickly participants could engage their temporal cortex and relieve the prefrontal cortex for car categorization tasks.
“This prompts many new inquiries,” Riesenhuber said. “What triggers this variation? The answer remains elusive.”
Optimistically, Schoenberg asserts that everyone possesses the potential to optimize their multitasking abilities, regardless of the decline in learning speed often seen in older age.
Frustration Can Impede Progress
Beyond patience and perseverance, few shortcuts exist for enhancing task efficiency.
“The study required around four weeks,” he explained. “The essential takeaway is that multitasking necessitates consistent practice for efficiency. Rapid improvement isn’t realistic. It demands time to form new neural pathways.”
Dr. David T. Jones, a Mayo Clinic neurologist, cautions that the brain has processing limits, so self-frustration can hinder multitasking efforts.
“Managing emotions is as demanding as sorting numbers or identifying images,” Jones added. “Self-criticism just adds to your cognitive load, making performance suffer.”
A practical strategy for handling multiple pieces of information is to break them into smaller, manageable segments, akin to how we handle phone numbers.
“Memorizing lengthy strings of digits isn’t necessary; we categorize them using dashes,” he explained. “Thus, three numbers become a single item, making it easier to hold that chunk in your memory.”
How AI Influences Multitasking
Schoenberg warned against excessive reliance on technology for multitasking, like using AI for writing or data analysis, which may counteract our brain’s developed multitasking capabilities. A new study indicates that our multitasking proficiency only emerges after gaining a specific level of expertise, showing that prolonged dependence on AI could obstruct the acquisition of complex skills.
“Mastery depends on our ability to recognize patterns; over-reliance on AI prevents that,” Schoenberg stated. “Developing efficient pattern recognition enhances our capacity to multitask, enabling quicker decisions and simultaneous integration of various elements.”
In 1993, DNA evidence played a critical role in solving a murder case in Idar-Oberstein, Germany, where a 62-year-old woman was found strangled. The analysis revealed that two other people were involved, hinting at a female suspect.
Fast forward to 2007, the infamous ‘Phantom of Heilbronn’ case surfaced in Germany, linking a woman’s DNA to 41 different crimes, sparking a massive manhunt. Ultimately, it was revealed that the phantom was a factory worker producing contaminated DNA swabs.
Turi King states, “DNA is not the silver bullet people think it is,” emphasizing its limitations as well as its strengths in solving criminal cases.
“You almost certainly carry the DNA of a loved one or work colleague with you.”
Dr. King highlights the impact of DNA analysis in historical cases, including the identification of King Richard III’s remains in 2012 through advanced genetic techniques.
DNA collected at crime scenes does not necessarily confirm involvement, as seen in the Amanda Knox case, where misinterpretations of DNA evidence led to wrongful convictions.
The book serves as a reminder of the dual nature of DNA analysis: while it offers powerful insights, it also comes with inherent risks of misinterpretation. Dr. King poignantly notes that the case of Knox illustrates how sensitive DNA detection can lead to wrongful accusations.

How Does Rachel Carson’s Silent Spring Hold Up Today?
Rachel Carson, a pioneering marine biologist, authored three impactful books on marine life and one transformative letter, prompting a shift in focus towards the environmental consequences of pesticides like DDT. This letter, published in the Boston Herald, highlighted the lethal impacts of DDT on Massachusetts bird populations, prompting Carson’s extensive research into pesticide effects and leading to her seminal work, Silent Spring.
Silent Spring emerged as a groundbreaking and influential text, heralding the modern environmental movement. As Margaret Atwood noted, Carson’s publication in 1962 fundamentally altered public perception on environmental issues. Following its release, President John F. Kennedy initiated investigations into the impacts of DDT and other pesticides, catalyzing the establishment of crucial environmental legislation including the creation of the Environmental Protection Agency in 1970 and pivotal laws like the Clean Air Act (1963) and Endangered Species Act (1973).
In Silent Spring, Carson begins with a vivid description of a fictional American town, once alive with flora and fauna, now silenced by industrial and agricultural pollution. She poignantly illustrates how pollution decimates ecosystems, posing threats to human health in just a few decades.
DDT, first used as an insecticide in 1939 and extensively employed during World War II, became a staple in post-war pest control. However, its widespread use raised environmental alarms, as documented in Silent Spring. Carson’s work revealed how pesticides and herbicides contaminated groundwater and air, impacting ecosystems beyond immediate targets. Dangers remain, as biologist Dave Golson points out, with pesticide approvals escalating from 37 in Carson’s time to 900 today in the U.S.
Carson’s insights into ecology and the interconnectedness of species were ahead of her time. She emphasized the ripple effects of pesticide use within food webs, illustrating the silent fallout across interconnected organisms. “Nature rarely operates in separate, closed compartments,” she wrote, shedding light on the profound web of life and its fragility.
The publication of Silent Spring involved immense personal courage. The chemical industry mounted extensive campaigns to discredit Carson, who tragically passed away from cancer in 1964, shortly after her groundbreaking work. Ironically, the carcinogens she chronicled may have contributed to her own health struggles.
Thanks to Carson’s contributions, we now recognize that pesticides can disrupt numerous species within ecosystems. Present-day research continues to investigate the untargeted effects of pesticides, including their influence on symbiotic relationships that are crucial for ecological balance.
Carson advocated for scientific solutions to crop protection while being acutely aware of climate change impacts. She eloquently articulated that “the history of life on Earth has been a history of interactions between living things and their environments.” Her work remains essential reading for understanding the intricate history of life and our responsibilities toward nature.
Silent Spring is a pivotal resource for anyone seeking insight into environmental history and future challenges. Carson asserted, “Man is part of nature, and man’s war against nature is necessarily a war against himself,” underscoring the intimate bond between humanity and the ecosystem.

A Ship is Coming In
We asked our readers, and you delivered. In our recent feedback request, we sought the most fitting adjective for the Wikipedia page discussing the Ship of Theseus paradox. To clarify, this philosophical puzzle explores whether an object remains the same when all its components are replaced. Interestingly, the Wikipedia page itself has undergone extensive editing, making it a prime example of the very paradox it describes.
In our mailbag, you’ll find a wide array of suggestions, including Tim Molesley’s “automatic paradigm” and Bryn Glover’s “automatic causes.”
Among the standout contributions was Martin Baston, who drew inspiration from the British sitcom Only Fools and Horses. In the show, the character Trigger receives a medal for maintaining the same broom for 20 years, albeit with 17 new heads and 14 new handles. Thus, Martin proposed describing the Ship of Theseus Wiki page as a “trigger.”
However, the prevailing consensus labels it “self-logical.” Peter Jeffrey, Peter Gutfreund, and others pointed out that an autological word expresses a characteristic it possesses. For example, “noun” is a noun, and “sesquipedalian” refers to a sesquipedalian.
Yet, there is a debate about whether “autological” can refer to entire articles. Philip Penton humorously suggested, “If you need another term for your article, consider ‘autobloomian.’”
Mairi McKissock also contributed valuable insights. She uncovered the opposite of autological—“foreignness,” a term that fails to describe itself. For instance, the word “monosyllabic” is inherently polysyllabic. This led Mairi to examine another intriguing paradox, the Grelling-Nelson paradox. “Is the word ‘alien’ foreign? If so, it proves itself to be autological. If not, it fails to do so and thus becomes foreign,” she posited.
Now that the feedback is yielding more questions than answers, let’s change direction and explore another segment of the mailbox.
Discovering Niche Markets
The conversation surrounding niche science-themed tourism continues steadily. Criteria for winning include parks adorned with foraminiferal sculptures or gardens exclusively made of moss.
Andrew Taubman, a volunteer at the Australian Museum, reported significant progress in digitizing their extensive entomology collection. He recently aided in the digitization of the Lamprogaster genus, which oddly lacks a dedicated Wikipedia page, showcasing how obscure these insects truly are. Similarly, Rosalinda Hardiman’s collection of handpicked beach pebbles, gathered during her years of open water swimming, is not publicly available. She seeks feedback on whether to exhibit them, and the response is a resounding yes.
In Australia, Sari Somerstrom introduced us to the Puseum in Richmond, Tasmania, which specializes in animal waste. Their website claims to be “the only facility of its kind in Australia”. According to Sari, the book is “not only interesting but packed with fascinating facts.” However, concerns arise about its niche appeal, given the universal nature of defecation.
Turning to John Blakey, he highlighted two hidden gems. The first is a Gas Museum in Hobro, Denmark, dedicated to the intriguing history of gas production and distribution. Though John hasn’t visited yet, he considers it a must-see.
Yet, John’s second recommendation truly stands out: Kornets Hus, or “House of Grain,” located in northern Jutland. This venue celebrates all things corn and grains, set in a dedicated center amid a cornfield. “It’s so obscure; no one has left a review on TripAdvisor,” John remarked, although there is a separate page for the museum café, which had a handful of reviews as of mid-May.
Precious Chihuahua
While I usually refrain from quoting feedback directly, this particular insight comes from renowned author Janet Winterson of Oranges Are Not the Only Fruit. While browsing Apple News, she noted the amusing use of dogs as a unit of measurement. A recent article mentioned a “giant 11,000-carat ruby worth millions,” likening its weight to that of a dog.
To highlight the absurdity of this comparison, an English Mastiff can weigh over 100 kg, while a Chihuahua might only weigh about 1 kg. Such comparisons invite confusion, much like stating that a building’s height lies somewhere between two stories and the Burj Khalifa. Further information reveals that this gemstone weighs around 2.2 kg, a weight consistent with a Chihuahua.

In today’s fast-paced world filled with work, family, politics, and captivating TV dramas, we often overlook the remarkable stories unfolding within our own bodies.
Our organs work tirelessly to provide essential oxygen, energy, and resilience, enabling us to embrace life’s joys while conquering its challenges.
In her insightful book, Julia Enders emphasizes that understanding our body’s complex systems, shaped over millennia, can inspire healthier, more meaningful lives. Organ Speak examines the question: what does it truly mean to listen to our bodies?
Enders, a physician specializing in gastrointestinal health, is renowned for her best-sellers like Gut, which humorously explores the intricacies of our intestines and discusses everything from flatulence to optimal bathroom posture.
In her new book, Enders celebrates the marvels of five vital systems: lungs, immune system, skin, muscles, and brain. With humor and clarity, she articulates complex biology, urging readers to pay closer attention to their bodily functions.
Each chapter explores the significance of various organs backed by recent scientific studies and personal narratives. For instance, she draws parallels between her late grandmother’s friend and the immune system’s protective role during life’s unpredictabilities.
“Our organs significantly shape our identities, influencing our responses to threats and our interactions with others,” Enders asserts. “Understanding your body can foster a more harmonious existence.”
Starting with the lungs, Enders describes their remarkable ability to inflate and deflate approximately 20,000 times daily. Consequently, pollution and other harmful elements challenge our respiratory health.
She highlights unusual breathing patterns, like “email apnea,” which causes many to hold their breath while checking emails, potentially leading to neck tension and fatigue. Practical solutions, including controlled breath-holding exercises, are also provided.
Transitioning to the immune system, Enders elaborates on its mechanisms against pathogens, humorously labeling a runny nose as “nasal diarrhea,” emphasizing its role in eliminating germs.
Moreover, she discusses allergies and autoimmune disorders resulting from immune misfires and offers advice on keeping immune cells healthy through proper sleep, nutrition, physical activity, and vaccinations.
Regarding skin health, Enders goes beyond surface-level concerns, explaining the physiological reasons behind aging and the positive impacts of touch, especially for premature babies.
To combat skin aging, she recommends using a vitamin C moisturizer at night and a vitamin A lotion with sunscreen during the day to neutralize free radicals.
When exploring muscle functions, Enders provides intriguing insights into muscle deterioration during inactivity, such as how prolonged bed rest can result in significant muscle loss.
Evidence supporting regular exercise is also presented, highlighting benefits like improved mood, heart health, and even neural development.
Lastly, she delves into brain function, discussing sleep deprivation effects, addiction, and suggesting strategies for better napping.
While Organ Speak may not introduce groundbreaking concepts, it is filled with lesser-known health tips that may be beneficial for readers. However, some sections where Enders presents organs as wise mentors can feel unconvincing, particularly when she asserts that skin care won’t alleviate emotional pain.
Enders also detours into broader topics, such as Earth’s atmospheric history when discussing lungs, potentially losing reader engagement. Nevertheless, Organ Speak is certainly insightful for those invested in their bodily health and may serve as a gentle reminder to prioritize personal well-being.
Consider taking a deep breath the next time you confront anxiety-inducing emails.

The 5-meter-long altar stone is mostly buried at the center of Stonehenge.
Laurence Berger/Getty Images
Recent research into Stonehenge’s enigmatic altar stone suggests it may have originated from northeast Scotland, possibly carried south by glaciers. However, scientists argue that it’s more plausible humans transported this six-tonne stone.
This striking 5-meter-long monolith has been situated at the heart of Stonehenge’s worked rock ring for around 4,500 years, partially buried beneath two other stones.
In a 2024 study, researcher Anthony Clark and his team from Curtin University in Perth determined that the altar stone’s origins lie in northeastern Scotland, based on detailed rock chemistry analysis.
Clark notes, “The altar stone is sandstone—like crushed grains of sand on a beach. We can fingerprint the age and chemical makeup of these particles and compare them to other rocks across the UK and Ireland.”
The chemical profiles revealed a match with rocks from the Orcadian Basin, confirming the altar stone must have traveled approximately 750 kilometers to reach Stonehenge in southern England.
Initially, Clark and his colleagues theorized that the altar stones were likely transported by boat. They also explored the possibility that glaciers may have facilitated this movement during the last ice age, reducing the distance for human transport.
Utilizing geological analysis and ancient ice flow modeling, they reconstructed glacier movements. Their findings indicated that while most ice flow from northeast Scotland headed north, some could have directed south, potentially delivering rocks to Dogger Bank. This land bridge connected Britain to mainland Europe until it was submerged beneath the North Sea about 8,000 years ago, long before Stonehenge’s construction began around 5,000 years ago.
If glaciers had indeed transported these altar stones to Dogger Bank, it could have significantly shortened the journey for humans.
However, the flooding of Dogger Bank makes this hypothesis increasingly complex. Given that other stones at Stonehenge weigh between 25 and 30 tons and were undoubtedly moved by humans over substantial distances, it’s likely they possessed the necessary skills and determination to relocate the altar stone as well.
Clark emphasizes, “The builders of Stonehenge were not rushed. Similar to the pyramids, this took years to accomplish; it didn’t need to be done within modern timescales.”
Ultimately, further sampling may help pinpoint the exact quarry from where the altar stone originated. However, the reasons behind this monumental endeavor may forever remain a mystery. “Why would we select certain stones for monuments?” Clark poses, drawing parallels to choosing premium materials for modern kitchens or treasured pieces of jewelry. “Humans have always been drawn to specific stones, and for some reason, these ancient Britons required sandstone from northeastern Scotland.”
One of the intriguing mysteries of Stonehenge is how its altar stone journeyed 700 km (435 miles) from Scotland to southern England. New research suggests that glaciers played a crucial role in its transportation.
At the heart of this ancient monument lies a massive sandstone slab, weighing 6 tonnes, which is believed to have arrived at Salisbury Plain approximately 5,000 years ago. Earlier studies pinpointed its origin to northeast Scotland, yet the route it took remains a fascinating enigma.
Researchers from Sheffield Hallam University and Curtin University in Australia, after examining ancient ice flows, believe that glaciers carried the altar stone from the Orcadian Basin in northeast Scotland to Dogger Bank during the last ice age, spanning from 33,000 to 11,700 years ago.
Today, Dogger Bank is submerged under the North Sea but was once part of Doggerland, a vast prehistoric landmass connecting Britain to mainland Europe. This area lacks natural sources of large stones, indicating that any found there were likely transported by glaciers.
Dr. Remy Venes, co-lead author of the study published in the Quaternary Science Journal, stated, “We recently discovered that the altar stone originated in northeast Scotland, but how it traveled 700 kilometers to Salisbury Plain remains widely debated.”
“These discoveries may suggest that the communities in Doggerland had already ascribed cultural significance to the altar stone long before it became part of Stonehenge,” Dr. Venes added.
Dr. Anthony Clark, co-lead author from Curtin School of Earth and Planetary Sciences, noted that the findings imply glaciers transported the altar stone to Doggerland, with Neolithic people then moving it to Stonehenge.
“Our models indicate that while glaciers may have carried the stone part of the way during the last Ice Age, Neolithic people still had to move it hundreds of kilometers to reach southern England,” Dr. Clark explained.
The study indicates that although glaciers assisted in the stone’s southern journey, researchers found no direct glacial route linking its Scottish origin to Stonehenge. Instead, they posit that Neolithic communities transported stones in stages, utilizing a combination of overland, coastal, and river routes.
This impressive feat of moving immense stones over long distances reveals a level of organization and collaboration among Neolithic communities that has previously been underappreciated. “Transporting stones of this magnitude across vast distances would require meticulous planning, coordination, a deep understanding of the landscape, and immense determination,” Dr. Clark emphasized.
While long, fluttering eyelashes are often associated with femininity, some alpha males seek to reaffirm their masculinity by altering their appearance and showcasing it on social media.
Did you know the average person has 90 to 160 eyelashes on the upper eyelid and 75 to 80 on the lower eyelid? – Image courtesy of Getty Images
This trend not only seems perplexing to me but also to eye care professionals. Trimming eyelashes typically involves using scissors or clippers dangerously close to the eyes.
Many find videos of this process uncomfortable to watch, pointing out that this trend is often more about creating controversial content rather than genuine practice.
Experts warn that a single mishap during trimming can result in significant harm to your cornea or the tear film, which is essential for keeping the eyes moistened.
Even if you’re cautious, the chances of exposing your eyes to unnecessary risks are high. Eyelashes play a crucial role in safeguarding our eyes.
They act as the last line of defense against dust, sand, and harmful UV rays. Just like lions and silverback gorillas, humans have evolved to have this natural protection.
Interestingly, the length and thickness of eyelashes are influenced by genetics, not gender. The stereotype that women have longer eyelashes while men have shorter ones is rooted in cultural perceptions rather than scientific fact.
Ultimately, trimming your eyelashes could lead to dry eyes, increased discomfort, a higher risk of infection, and the ridicule that may follow.

Euprothes Gigatrochus, a newly identified species of ciliate organisms, found in a seawater filtration system on the Caribbean island of Curaçao, exhibits the potential to develop into cannibalistic “supergiants.” This discovery raises intriguing questions about the complexity of microscopic life.

“Ciliates of the genus Euprotes have captivated researchers since the advent of microscopy due to their widespread presence and unique characteristics,” stated lead author Dr. Ben Larson from Rensselaer Polytechnic Institute and colleagues.
The genus Euprotes is prevalent in various aquatic ecosystems and has been extensively studied concerning their movements, mating rituals, symbiotic interactions, distribution, and adaptations to environmental conditions.
These ciliated cells possess a highly structured and complex animal-like morphology, featuring cilia organized into membranous cells that are specialized for feeding (by generating water currents), swimming, and moving across substrates.
Among these organisms, Euprothes Gigatrochus was recently collected from a seawater filtration system in Curaçao.
In clonal populations, where all cells contain identical DNA, some cells can spontaneously evolve into supergiant forms, exceeding normal cell lengths by more than twofold, characterized by broader bodies and larger mouths.
Supergiants transition from filtering and consuming bacteria to becoming predatory hunters, capturing smaller cloned relatives at a remarkable rate of one every ten minutes.
“This single-celled organism exhibits behaviors typically associated with multicellular development,” Dr. Larson remarked.
“This expands our understanding of the capabilities within single-celled organisms and provides a new framework for investigating how cells regulate their form and function.”
The researchers assert that the behavioral adaptations extend beyond feeding.
Normal cells navigate surfaces and gracefully swim along spirals, while supergiants employ a distinct circular locomotion suitable for hunting prey, awkwardly rolling when displaced from surfaces.
“Supermacrogenesis is a strategic trade-off; while these cells excel at hunting, they sacrifice swimming efficiency, thus shifting their dietary focus from bacteria to larger prey,” Dr. Larson explained.
To delve into the molecular basis of these transformations, the authors sequenced transcriptomes from Euprothes Gigatrochus normal cells, supergiant cells, and those reverting from supergiant stages.
The findings reveal that supergiants represent distinct developmental stages, showcasing significant variations in gene expression related to cell cycle control, protein synthesis, and membrane organization.
Cells reverting from the supergiant state display distinctive molecular profiles that temporarily inhibit pathways driving transformation.
Populations derived from recently reverted cells exhibit a slower emergence of new supergiants compared to those initiated from normal cells, regardless of external conditions.
Supergiant cell formation typically occurs as populations transition from rapid growth to a stationary phase, particularly in the absence of small prey. They remain present only as long as small prey is scarce and larger ones (normal cells) are available.
Supergiants constitute no more than 5% of the population, which aligns with a bet-hedging strategy where a minority of cells explore alternative resources.
This groundbreaking discovery offers a fresh perspective on the development of unicellular organisms, which must execute cellular and organism-level functions within a singular membrane.
“Most of our developmental knowledge is derived from multicellular organisms,” Dr. Larson noted.
“Similar developmental processes are at play in single-celled organisms across various branches of the tree of life, paving the way to study fundamental biological questions in new contexts.”
The details of this study will be published in Proceedings of the National Academy of Sciences.

Bryozoans, small colonial animals, were traditionally believed to have appeared millions of years after the Cambrian explosion. However, remarkable fossils discovered in 520 million-year-old rocks in China reveal that these fascinating creatures have been present since the dawn of time.

“Bryozoans are small, filter-feeding, colonial invertebrates that continue to thrive in the world’s oceans today. Yet, their origins remained a mystery for decades,” noted paleontologist Dr. Timothy Topper from Northwest University and the Swedish Museum of Natural History.
“While nearly all other major animal groups emerged during the Cambrian explosion around 530 million years ago, the fossil record for bryozoans remained conspicuously absent until the Ordovician period, roughly 50 million years later.”
In a groundbreaking study, paleontologists analyzed a stunning bryozoan fossil from the early Cambrian Sennudo Formation in China.
The samples represent two species: Protomerision Gatehouse and a newly recognized taxon, Daingomellission Hexacritia.
“For too long, bryozoans have been the missing link in Cambrian paleontology,” Dr. Topper stated.
“Except for bryozoans, all other significant animal phyla have Cambrian representations. This discovery definitively closes that gap.”

This discovery not only fills a significant gap in the fossil record but also has profound implications for our understanding of the tree of life.
Phylogenetic analysis firmly places both Protomerision Gatehouse and Daingomellission Hexacritia within the Crown Group Stenolaemata, one of the three main classes of living bryozoans.
Since these fossils represent a more advanced branch of the Bryonidae family tree, their existence suggests that the origin of the entire group might date back to the Ediacaran period, even before the Cambrian explosion.
This study also confirms that Protomerision Gatehouse is indeed a bryozoan, despite some researchers proposing it might be a sclerotid derived from green algae or another unrelated organism.
New soft tissue data, along with detailed comparisons of colony size, shape, and internal structure, refute these alternative interpretations, clearly solidifying their association with bryozoans.

“These are not merely precursors; they are complex, modular colonies,” asserts paleontologist Baopeng Song from Northwest University.
“The combination of skeletal structure and internal anatomy provides definitive evidence that these represent true bryozoans, indicating that this phylum was already diversifying during the Cambrian radiation.”
“Together, the two Chinese taxa and previously reported Cambrian material from South Australia suggest that bryozoans were not only widespread in the early Cambrian oceans but also highly sophisticated in their development.”
“The concept of colonial body planning, where genetically identical individuals known as polypids cooperate within a communal skeleton, appears to have evolved as a core innovation of the Cambrian explosion itself rather than a late development.”
The team’s paper is published in the latest edition of Nature.

Keto Diet: A High-Fat, Low-Carb Solution for Anorexia
Credit: Panther Media Global / Alamy
The ketogenic diet, famed for its fat-burning potential, is showing promising results in treating anorexia nervosa. Recent research indicates that three out of four participants with eating disorders fell below diagnostic criteria while on a diet rich in fats, moderate in protein, and very low in carbohydrates. This dietary shift is believed to restore energy release in brain cells disrupted by anorexia, thus alleviating anxiety and the compulsion to restrict food intake.
This method mimics a state of starvation through carbohydrate restriction, which can lead to severe health risks. Studies show that anorexia is one of the mental health conditions with the highest mortality rates. However, Guido Frank, a researcher at UC San Diego, emphasizes that with proper supervision, the destructive urge to self-starve can potentially be mitigated. “Clinicians describe it as akin to an addiction. If we could stimulate a craving for food while ensuring adequate intake, it may be advantageous,” he explains.
Frank and his team conducted a 14-week study with 22 women suffering from anorexia whose body mass index (BMI) had improved to a range between healthy weight and slightly underweight. Under the guidance of a nutritionist, psychiatrist, and a peer support counselor experienced in anorexia treatment, these women followed a ketogenic diet. Their weight, mood, and anorexia symptoms were closely monitored each week, with surveys assessing changes in body image, depression, and food-related anxieties.
The results were significant: 18 women adhered to the ketogenic diet for the full 14 weeks, reporting considerable improvements in their anorexia symptoms and depression scores. Remarkably, 13 of these women (72%) fell below the clinical diagnostic thresholds for both conditions. According to Frank, “The recovery levels were far superior compared to other treatments for anorexia.”
Although the primary focus of the study was not weight gain, all participants maintained values within a slightly underweight but healthy BMI range and did not experience relapses.
The ketogenic diet derives its name from the metabolic adaptations it promotes to help the body endure periods of famine. Typically, our metabolism is carbohydrate-driven, converting these sugars into glucose, which is then utilized in the mitochondria for energy.
In the absence of carbohydrates, the body shifts to burn fat, releasing stored fat and converting it into ketone bodies in the liver. These ketone bodies serve as an alternative energy source in the mitochondria instead of glucose.
Initially developed in the 1920s for epilepsy treatment—not weight loss—the ketogenic diet mirrors starvation while providing sufficient dietary fats to prevent significant weight loss. This diet aims to replicate the fasting state, known for reducing seizure activity, offering a more sustainable treatment option.
Recent studies have revealed a correlation between various mental health issues, such as epilepsy and anorexia, and dysfunctions in glucose energy release in the brain. Ketone bodies may alleviate this dysfunction by supplying a different energy source.
Dr. Sahib Khalsa, a professor at UCLA specializing in eating disorder research and treatment, cautions those considering the ketogenic approach for anorexia. “It’s vital to differentiate between supervised treatment by a professional team and attempting this on your own. Until larger randomized controlled trials are conducted, it risks premature changes in anorexia management protocols, which typically include therapy and nutritional support,” she notes.
In 2016, waves supercharged by El Niño impacted the California coast.

Recent headlines have been buzzing with news about the impending “Godzilla El Niño.” In reality, there’s an 80% chance of an El Niño developing by September. While most climate models forecast a moderate event, some hint at the possibility of a stronger Super El Niño.
However, the broader outlook remains concerning. Regardless of its intensity, we can expect more damaging El Niño events in the coming decades. Even if these events are less powerful, their effects will be pronounced in an increasingly warmer world.
As Axel Timmermann from the Busan National University states, “Even a standard El Niño could create larger regional and global impacts.” His research indicates that both El Niño and La Niña events—collectively referred to as ENSO events—are predicted to become stronger and will increasingly influence weather patterns across the Atlantic Ocean.
Timmermann’s team has found that computer model simulations predict intensified extremes for El Niño-La Niña phenomena, leading to a more pronounced impact in remote regions, especially Europe.
The El Niño phenomenon is fundamentally about the water and wind dynamics in the Pacific Ocean. During the neutral state, trade winds push surface water westward, creating warm water accumulations in the western Pacific. Meanwhile, cold water rises near South America, replacing the warm water displaced by these winds, leading to increased rainfall.
However, when trade winds weaken or reverse, warm water can flow eastward, shifting rain patterns and triggering positive feedback loops that amplify El Niño events. This shift can cause droughts in countries like Australia and Indonesia while leading to floods in South America.
This is also why El Niño contributes to rapid global warming. A larger expanse of warm water enhances evaporation, releasing energy as latent heat and transferring heat into the atmosphere.
El Niño’s intensity is gauged by how much warm water flows east towards South America, often indicated by sea surface temperature anomalies exceeding 0.5°C. While “Super El Niño” is not a scientific term, it is often defined by temperature increases above 2 degrees Celsius; “Godzilla El Niño” references temperatures above 3 degrees Celsius, as noted by Adam Scaife from the Met Office Hadley Centre.
As El Niño unfolds, negative feedback loops can emerge, such as increased cloud cover over the central Pacific, which can lead back to neutral conditions or even shift to La Niña, where stronger westerly winds push cold water westward.
The three strongest El Niño events recorded occurred in 1982-83, 1997-98, and 2015-16, each causing significant harm to ecosystems and human populations, including mass mortality of corals and marine life.
Each Super El Niño has resulted in economic damages amounting to trillions of dollars. A 2023 study by Christopher Callahan from Indiana University found a direct correlation between the magnitude of economic loss and the intensity of Pacific ocean temperatures: “If a major El Niño occurs this year, we should anticipate economic losses in the trillions, similar to past events.”
As global temperatures rise, future El Niños and Super El Niños will likely become increasingly damaging. Richard Allan from the University of Reading, UK, states, “The science is clear.” He emphasizes that ENSO-related flooding is expected to worsen due to increased atmospheric moisture, leading to more intense rainfall during storms. Hotter conditions will also exacerbate droughts, causing longer and more severe dry spells.
Some climate models propose that warming could amplify the feedback mechanisms driving ENSO events, possibly leading to greater intensity in both El Niño and La Niña, and quicker transitions between the two, referred to as “climate whiplash.” This may complicate society’s adaptation to environmental changes.
“This means greater fluctuations between wet and dry years for numerous regions,” explains Malte Stucker, a member of Timmermann’s team at the University of Hawaii.
Worse yet, the team’s research suggests that these intensified fluctuations could synchronize ENSO events with the North Atlantic Oscillation. If this occurs, Europe may experience significant variability in flooding and drought patterns.
“Such a change would be a major shift for Europe since El Niño typically has minimal influence on its weather patterns under current conditions,” Stucker notes.
Though there is strong evidence suggesting that future El Niños of similar magnitude will cause more destruction, the likelihood of El Niño events intensifying remains highly debated. “There are substantial disagreements regarding the future behavior of El Niño and La Niña,” Scaife points out.
Not all climate models predict an intensification of El Niño, yet many do connect it closely with regions like the Atlantic Ocean, suggesting that El Niño’s impacts across the Pacific may strengthen in the coming years.
Even if ENSO events do intensify, they won’t continue to do so indefinitely, according to Timmermann. He notes that this intensification is partly due to rapid warming of water approximately 100 meters deep across the Pacific; ENSO events may weaken as groundwater temperatures equilibrate and differentials decrease.

Key Optical Components in Quantum Computers by Atom Computing
Credit: Atom Computing
The quest to establish the first truly efficient quantum computer has become even more thrilling. An innovative quantum computer utilizing ultra-cold atoms has achieved critical milestones, joining a select group of promising quantum technologies.
Experts agree that a powerful quantum computer could revolutionize our ability to discover new materials, develop drugs, and secure online communications. However, divergent methodologies exist regarding the optimal approach to building these systems. Tech giants like Google and IBM have invested a decade into developing quantum computers based on tiny superconducting circuits, which currently lead the market.
In contrast, a groundbreaking method employing electrically neutral, ultracold atoms is garnering renewed attention. Ben Bloom of Atom Computing and his team have successfully developed a neutral atomic quantum computer capable of continuously detecting and rectifying errors—an essential feature for practical applications.
“This achievement highlights the potential of neutral atomic systems,” he explains. “Previously, we focused on incremental advancements; now, our aim is to enhance efficiency and affordability.”
The team prioritized error correction—the ability of quantum computers to identify and rectify errors during calculations. Quantum computers, prone to errors, face significant challenges in reliability, and effective error correction is vital for their practical implementation.
Error correction requires distributing information among multiple quantum bits, called qubits. Specific qubits act as a monitoring system to identify errors, enabling corrections.
The Atom Computing team demonstrated that they could increase the number of error-correcting qubit groups from 16 to 32 without introducing additional errors. Notably, a larger grouping of qubits correlates with a lower error rate, a critical factor as enhancing qubit count in a quantum computer amplifies its capability.
In recent studies, Google researchers, alongside experts from the University of Science and Technology of China, have successfully increased the number of qubits while minimizing error rates in superconducting quantum computers. In 2025, a research team from Harvard University reported similar advancements using another neutral atomic quantum computer. Bloom emphasized that their experiment stands out as it allows the quantum system to operate and check for errors up to 90 times consecutively. “Our ultimate objective is infinite error correction,” he notes.
Addressing industrial challenges necessitates both a high volume of qubits and uninterrupted computation. Atom Computing asserts that its research lays the groundwork for achieving both. “This study marks the first demonstration of all necessary functionalities for constructing a fully operational neutral atomic quantum computer,” states Jeff Thompson of Princeton University. He highlighted the demanding experimental feats required, noting that further enhancement in error rates and computational speeds remains feasible.
Mark Saffman at the University of Wisconsin-Madison stressed that this progress represents a critical step towards a neutral atomic quantum computer capable of continuous operation akin to traditional computing systems. Nevertheless, Safman pointed out that the quantum computer, despite completing 90 error checks, accumulated additional errors over time, affecting its practicality.
Bloom and his team are actively working on error resolution strategies and are optimistic about improving quantum computing performance. He believes that their latest findings, coupled with parallel research efforts, position neutral atomic quantum computers as formidable contenders to existing solutions involving superconducting qubits.
“Our research indicates that many of the barriers preventing neutral atoms from rivaling superconducting qubits are diminishing,” Bloom asserts. Thompson shares this sentiment, predicting rapid advancements will persist throughout the industry.
United Nations researchers are advocating for a reduction in politeness towards artificial intelligence (AI) to lower energy consumption.
A study from the United Nations University Institute for Water, Environment and Health (UNU-INWEH) reveals that omitting polite phrases like “please” and “thank you” from AI prompts can decrease ChatGPT’s energy usage by 25%, saving between 87 and 98 gigawatt-hours of electricity annually. This is comparable to the yearly electricity consumption of up to 760,000 households in sub-Saharan Africa.
To curb energy consumption and minimize carbon emissions, it’s essential to craft concise prompts, steer clear of conversational loops, and avoid emotional attachments to AI, according to the researchers.
Kave Madani from UNU-INWEH states, “We’re not advocating disrespect towards AI, but it’s crucial to evade the interaction trap and not become overly engaged.” Learn more about Kave Madani.
The AI model behind chatbots processes text in small units known as tokens. Concise prompts save energy by decreasing the number of tokens the model needs to analyze and generate for responses. Shorter prompts can simplify tasks and further reduce power requirements.
The recent United Nations study is one of the most thorough evaluations of AI’s environmental costs. It warns that the rapid rise in AI technology is significantly escalating energy, land, and water use.
Currently, ChatGPT handles around 2.5 billion queries each day, while Google processes 16 billion, most of which include AI-generated summaries.
Due to the lack of disclosures from tech companies regarding energy use, researchers utilized data available from their data centers.
AI accounts for approximately 20% of energy consumption in data centers, with projections indicating this could rise to about 40% in the coming years. By 2030, AI might consume around 378 TWh annually, while total data center consumption could reach 945 TWh, representing nearly 3% of anticipated global electricity demand.
The projected 9.3 trillion liters of water required for data centers by 2030 is sufficient to meet the annual basic domestic water needs of all 1.3 billion residents in sub-Saharan Africa.
As Miriam Axel from UNU-INWEH points out, “Technologies are being adopted globally at an unprecedented rate, leading to a swift rise in energy consumption.” Discover more about Miriam Axel.
The researchers assert that while AI companies should be mandated to disclose their energy usage, and governments should impose energy restrictions on businesses and individuals, public education on efficient AI use is equally critical.
Madani emphasizes the importance of minimizing unnecessary AI usage and suggests using fewer words and less powerful models when engaging with AI.
It’s also noteworthy that generating an image consumes 60 times more energy than a text query, enough to power a 10-watt LED light bulb for about 17 minutes. In contrast, a complex video could use up to 8000 times more energy than text, powering that same light bulb for approximately 1.7 days.
“AI isn’t inherently bad,” Madani concludes. “We should just use it wisely. It’s like a knife: it can save someone’s life in surgery, or it can be misused.”
The 27 degrees east meridian divides the Earth into two equally reflective halves.
Planetary Visions Limited/Science Photo Library
A significant line traversing Africa, Europe, Alaska, and the poles creates a division in the Earth that reflects equal amounts of light. This symmetry could have a vital influence on Earth’s climate system.
Research shows that the northern and southern hemispheres exhibit nearly equal albedo, with findings from Jiang Hao and colleagues from the National Oceanic and Atmospheric Administration revealing an additional line of symmetry at 27 degrees east longitude and 153 degrees west longitude.
The hemispheres defined by this line demonstrate equality in three aspects: clear sky albedo, cloud reflectance, and ice-free ocean coverage. This symmetry has been consistent throughout 25 years of satellite data analyzed by Zhang et al.
Initially, Zhang suspected this symmetry might be coincidental. “Three factors led me to believe that East-West symmetry is significant: its uniqueness, its long-term persistence, and its triple symmetry nature,” he states. “Finding a stable, unique east-west split that balances land and ocean distribution alongside clear and cloudy sky reflectivity is no small feat, especially considering the dynamic nature of clouds.”
Analysis of 25 years of satellite data shows that while the east-west symmetry centers around 27 degrees east, its exact position shifts slightly year to year. Researchers have linked these minor fluctuations to the phases of the El Niño Southern Oscillation (ENSO), a global climate phenomenon tied to changes in Pacific Ocean temperatures.
“This symmetry could be more than just geometric happenstance,” says Zhang. “It may be involved in significant climate change mechanisms. ENSO could serve as a substantial adjustment factor that helps sustain long-term east-west symmetry centered at 27 degrees east.”
According to Ovind Hodnebrok from the International Center for Climate Research in Oslo, Norway, who was not part of the study, there were initial doubts regarding these findings.
“I was initially skeptical about the east-west symmetry at approximately 27 degrees east longitude. It seems intuitively less clear than the equatorial separation, leading me to suspect it could be coincidental,” Hodnebrok notes.
However, he now agrees that it may represent a “robust feature and potentially an intriguing characteristic of Earth.”
Hodnebrok also highlights the importance of ENSO connections. Unlike the north-south symmetry, which is reportedly weakening due to climate change impacts on sea ice and cloud formation, the east-west symmetry remains stable—though models suggest it could weaken over time, potentially indicating shifts in atmospheric circulation.
Martin Uecker and researchers at the University of New South Wales in Sydney assert that the east-west symmetry might simply be coincidental.
“Weather patterns and climate easily interact across longitudes due to the Earth’s rotation, which creates easterly and westerly wind bands that orbit the planet, facilitating east-west atmospheric perturbation propagation,” Uecker explains.
Zhang notes that mechanisms maintaining east-west symmetry could have significant implications for geoengineering initiatives. For instance, attempts to enhance albedo in one hemisphere might be undermined by broader feedback loops.
“To confidently assert claims about geoengineering effects, we must deepen our understanding of how clouds, circulation, precipitation, and planetary reflectivity interact within the Earth system,” Chan states.
Pluto’s status in the solar system is once again under scrutiny, thanks to remarks from new NASA Administrator Jared Isaacman during a recent Congressional hearing.
“I’m strongly in favor of reclassifying Pluto as a planet,” he stated, highlighting a growing movement among planetary scientists advocating for Pluto’s reinstatement.
Since astronomers voted to relegate Pluto to ‘dwarf planet’ status in 2006, numerous researchers and members of the public have rallied for a reversal of this decision.
The reasoning is straightforward: Pluto is spherical, showcasing complex geology, including mountains, glaciers, and even a tenuous atmosphere. It certainly appears more planetary than a mere collection of cosmic debris.
Despite Isaacman’s endorsement, many astronomers remain hesitant to promote Pluto, cautioning that this could lead to a cascade of similar claims for other celestial bodies.
If Pluto is reclassified as a planet, it may open the door for numerous other celestial entities, possibly even our moon, to receive similar recognition.
The Divided Planet Debate
The ongoing Pluto debate traces back to the early 2000s. With the advent of more advanced telescopes and thorough exploration of the outer solar system, astronomers have identified a plethora of icy worlds beyond Neptune, many of which resemble Pluto. Notable among them is Eris, discovered in 2005, estimated to be about one-third as massive as Pluto.
A difficult question arose: if Pluto is classified as a planet, shouldn’t Eris be considered one as well? And how far does this classification extend?
This inquiry was presented to the International Astronomical Union (IAU), the body responsible for celestial nomenclature. On August 24, 2006, the IAU established a new definition for a planet, which requires that a celestial body:
orbits the sun
is massive enough for its gravity to form it into a round shape
has cleared the area around its orbit
Pluto did not meet the last criterion and was thus downgraded to ‘dwarf planet’ status, a classification that has sparked debates among planetary experts for nearly two decades.
This ‘clearing the neighborhood’ requirement poses challenges, especially at greater distances from the Sun, where a planet’s orbit expands and necessitates greater mass for effective neighborhood clearing.

This has led critics to argue that the IAU’s definition is inherently biased against Pluto.
“Based on the IAU definition, Earth qualifies as a planet in its current position, but if moved beyond the solar system, it would no longer fit that classification, which seems illogical,” explained Dr. Alan Stern, a leading planetary scientist at the Southwest Research Institute in Texas.
“Classification should not solely depend on location,” he added.
Stern is not alone in this sentiment. Just five days after the IAU’s announcement, a petition with signatures from over 300 professional planetary scientists was raised, which is significant considering only 411 individuals initially voted on the new definition.
The controversy surrounding Pluto persists. A 2018 study determined that even after 12 years, many planetary scientists have yet to adopt this definition.
Additionally, a 2024 paper pinpointed another fundamental flaw: the first requirement, that a planet must orbit the sun, excludes exoplanets revolving around other stars.
“Currently, there is no ‘official’ definition for exoplanets from a legitimate scientific nomenclature authority,” stated Dr. Hannah Wakeford, an astrophysicist at the University of Bristol.
“The IAU definition falls short when applied beyond our solar system. If this definition were utilized in the Proxima system, which has three stars in mutual orbit, the stars themselves could mistakenly be classified as planets.”
A New World Order
So what could be the remedy? Instead of focusing on where a body resides, some scientists, including Stern, argue that planets should be defined by what they are.
“It’s quite simple,” Stern asserted. “A planet is an object in space that is a) large enough to be shaped into a sphere by its own gravity, and b) not large enough to ignite through nuclear fusion, which are stars. That’s the definition.”
This redefinition would not only restore Pluto to its planetary status but also elevate Eris and numerous dwarf planets discovered in recent decades, including Haumea, Makemake, and Sedna, along with Ceres, the only dwarf planet in the inner solar system.
In total, Stern’s proposal could classify over 100 celestial objects as planets in our solar system, including our moon, which satisfies the criteria for roundness, geological complexity, and has six times the mass of Pluto.
“It’s incredible how many planets have been identified in our solar system and beyond,” Stern remarked. “The perspective that there are only a few planets comes from outdated beliefs from the 19th and 20th centuries.”

However, not everyone is onboard with such an expansive classification. Mike Brown, who discovered Eris and many other dwarf planets, fears that this defining method dilutes what it means to be a planet.
“Classification is fundamental for science’s understanding of phenomena,” Brown said. “If we miscategorize, we begin to ask misleading questions.”
He views the push for a modified definition as more of a strategy to restore Pluto as a planet, arguing that this topic was not previously entertained until after Pluto’s demotion.
Americans have a particularly strong attachment to Pluto, which was discovered in 1930 by astronomer Clyde Tombaugh. During his Congressional address, Isaacman emphasized the importance of recognizing Tombaugh’s contributions to astronomy.
Isaacman’s assertion to restore Pluto’s planetary status mirrors political rhetoric, indicating that motivations may intertwine science and politics.
Despite gaining the support of the NASA administrator, Pluto’s future ultimately relies on the IAU, an independent international body, which has shown no signs of revisiting this debate.
Ultimately, whether Pluto is categorized as a planet or not may hold less significance than the ongoing interest it generates. Its status has not diminished its prominence in scientific studies and it has even inspired the naming of an entire class of celestial bodies: dwarf planets within the Kuiper Belt.
“In my view, Pluto has ascended to the throne of dwarf planets, exemplifying its category and showcasing fascinating characteristics. Yet, is that really more prestigious than being labeled an average planet?” Wakeford remarked.
While biologically minimal, hair holds significant meaning in our lives. A contemporary emblem of youth, vitality, and aesthetic appeal, both the presence and absence of hair profoundly influence our self-perception and how others perceive us.
What makes hair so crucial to our identity?
Dr. Fabio Zucchelli, a psychologist at the University of the West of England, attributes this to an innate desire for conformity.
From an evolutionary psychology standpoint, the need to belong drives many of our feelings about appearance. When hair begins to thin, it may feel like we deviate from established norms.
However, our perspectives on hair are not set in stone. “Much of our perception of attractiveness is socially constructed,” Zucchelli clarifies. “Standards of beauty shift over generations and even within the same generation.”
Curiously, baldness has been admired throughout history, from ancient Egypt to the 18th century and the present-day people of Isini in Ghana.

Today, hair symbolizes youth, directly correlating with attractiveness and social worth. For women, it’s often seen as a marker of femininity and beauty, while for men, it signifies masculinity and youth.
This cultural significance underpins the rapid growth of the hair restoration industry, valued at 6.5 billion dollars (around 5.23 billion pounds). Projections suggest substantial increases in this market from now until 2030, indicating a strong societal impulse to treat hair loss.
“In my view, the growing medicalization of hair loss problems perpetuates the issue,” Zucchelli notes, emphasizing the escalating efficacy and costs of hair treatments.
Ultimately, whether to “fix” your baldness is a personal choice. For many, it marks a new chapter in their life, rather than a flaw worth erasing. If you decide against or cannot pursue restoration treatments, numerous effective strategies exist to bolster confidence and self-acceptance.
1. Emphasize Functionality
A beneficial approach involves reframing your body image. Instead of fixating on appearance, redirect your focus toward your body’s functionality.
For instance, skin serves as a protective barrier against infections while regulating temperature, and hair provides insulation and aids in sweat evaporation.
Acknowledging these biological functions can help shift your mindset toward self-acceptance.
“Fostering a positive body image can help guard against the emotional toll of hair loss,” says Zucchelli.
“This can be achieved through writing exercises that encourage awareness of your body’s capabilities.”

An innovative program promoting this mindset is Expand Your Horizon, developed by Dr. Jessica Alleva and her colleagues at Maastricht University. This evidence-based method encourages individuals to document their bodies from a functionality-focused perspective.
One of the exercises involves writing uninterrupted about your body’s appearance and sensations for at least 15 minutes.
Research indicates its effectiveness.
“Post-intervention, participants in the Expand Your Horizon program reported lower levels of self-objectification, increased satisfaction with their appearance, functionality, and body appreciation,” according to a study published in Body Image by Areva and colleagues in 2015.
The objective is not self-love, but self-neutrality, aiming to reduce self-objectification and foster a healthier body image.
“A common misconception is the necessity of self-love,” explains Zucchelli. “It may not be realistic for everyone to love their appearance consistently.”
“Instead of focusing on loving your hair, aim for accepting it as part of you. Acceptance is crucial,” he emphasizes.
2. Enhance Media Literacy
A vital strategy to alleviate the emotional impact of hair loss involves reevaluating how we perceive hair-related media.
“We must critically examine all that we consume,” advises Zucchelli. “Understand how external influences shape your beliefs regarding hair loss.”
This concept, known as media literacy, involves recognizing the influences on body image from advertising, algorithms, celebrities, and social circles.
“The hair restoration industry is worth billions and is rapidly expanding,” states Glenn Jankowski, a health and social psychology assistant professor at University College Dublin, whose research centers on male body image.
“This influence is pervasive across both media and the internet, where ostensibly unbiased information often serves as marketing for treatments.”

To counteract this, he suggests probing the commercial affiliations behind any hair loss-related content you consume.
“When reading articles, examine if there are sponsorships or corporate ties,” recommends Jankowski.
More structured tools, such as the DISCERN questionnaire from the University of Oxford, can help assess the quality of health treatment information.
This assessment consists of 16 questions to help evaluate whether treatment information is balanced, evidence-based, and transparent about risks and benefits to detect potential biases.
Sample questions include:
Are the sources used to compile the article clearly stated?
Are alternative treatment options acknowledged?
Is there an explanation of how each treatment functions?
Our digital landscape is saturated with algorithmically targeted advertisements. A single inquiry into a hair loss treatment can trigger a barrage of ads over subsequent weeks.
Even if reducing social media use isn’t on your agenda, consider adjusting your ad preferences to minimize exposure to unwanted topics.
Zucchelli describes a critical view of the media we consume as a “protective shield” for our body image, empowering you to ask yourself why certain feelings arise and who benefits from them.
Recognizing these influences can be liberating.
“It can significantly empower individuals,” Zucchelli notes.

3. Connect with Others Sharing Similar Experiences
Hair loss can feel isolating, but remember, you are not alone. Baldness is a common aspect of aging that affects many.
Bald men abound, from celebs like Dwayne “The Rock” Johnson and Jude Law to family members or acquaintances who reminisce about their once-full heads of hair.

“I refer to these men as ‘hidden bald guys’—they’re more prevalent than one might think,” says Jankowski.
Across history, numerous influential bald figures, from Winston Churchill to ancient Egyptian leaders, have left their mark.
Including other types of hair loss like alopecia areata (autoimmune condition causing patchy loss), cicatricial alopecia (inflammation causing permanent loss), and chemotherapy-induced alopecia makes it evident that over half of us experience some form of hair loss.
If you’re experiencing hair loss, remember: you’re not alone. Connecting with others can foster community and facilitate acceptance.
“For some, discussing hair loss experiences with peers can accelerate the acceptance journey,” Zucchelli notes.
Online forums and support groups prove beneficial, especially if you lack personal connections dealing with similar challenges.
Approach them cautiously, as not all support networks are conducive; some may push medical solutions that invite comparisons. Seek spaces where empathy prevails over competition.
“Engage with others and share experiences—building a sense of community can be immensely powerful,” Jankowski advises.
4. Seek Expert Guidance if Necessary
Unfortunately, despite employing the previous strategies, hair loss can still impact your mental well-being. If feelings become overwhelming, consulting a mental health professional can provide coping mechanisms.
Zucchelli advocates for acceptance and commitment therapy (ACT) as particularly effective in addressing hair loss-related concerns. ACT enables individuals to acknowledge distressing thoughts and feelings without self-judgment while taking meaningful actions aligned with their values.

A crucial aspect of ACT is learning to perceive thoughts as mere thoughts, rather than truths—especially the misleading notion that baldness diminishes your romantic prospects. Distancing from these detrimental beliefs allows greater focus on what genuinely matters in life.
A common ACT technique involves recognizing and naming your thoughts: for instance, “I feel like my baldness is more noticeable.”
The ACT framework can also aid in managing unwanted attention or inquiries about your appearance by guiding your responses and permitting you to disclose as much as you’re comfortable sharing.
ACT isn’t the only therapeutic avenue available; cognitive behavioral therapy (CBT) can tackle unproductive thoughts, while counseling offers a supportive space for emotional processing, and group therapy provides connections with individuals who understand your experiences.
5. Allow Yourself Time
Lastly, be gentle with yourself. Hair loss denotes a form of loss, and feeling sad is a natural response.
“Give yourself time to adapt to these changes; it’s perfectly acceptable,” Zucchelli reassures.
While the journey through baldness can feel daunting, the process often becomes easier once you accept this change. In the end, the reflection in the mirror is simply the new you.
As Jankowski wisely notes, many content bald men recognize the truth: “Actual hair loss is often more subtle than perceived.”
Unless you’re a lentil-loving vegetarian who enjoys bean burgers over beef, your body is likely craving the essential fiber it needs.
This is true for 95% of adults in England and the US. As a result, many miss out on the roughage essential for keeping gut microbes happy, immune systems strong, stools soft, and hearts healthy.
However, incorporating fiber into every meal—including fruits, vegetables, whole grains, beans, and legumes—can feel overwhelming, especially if you’re used to a low-fiber diet.
If you’re looking to increase your fiber intake, breakfast is an excellent place to begin. This meal is often considered the “most important meal of the day” because what you consume in the morning sets the stage for the day ahead.
Starting your day with a fiber-rich breakfast not only simplifies your fiber consumption but also enhances the overall effectiveness of your nutrient intake. Here’s why:
Prepare for the Day
Research indicates that your breakfast choices can significantly influence your lunch, dinner, and snack selections throughout the day.
In fact, Australian research revealed that adults who consumed a high-fiber breakfast were more likely to make healthier, fiber-rich food choices for the remainder of the day compared to those who skipped breakfast or opted for lower-fiber options.

“Eating a balanced breakfast facilitates healthier eating for the rest of the day,” states Dr. Emily Leeming, a nutritionist at King’s College London. “It’s intuitive: breakfast prepares you for the day ahead.”
This is because fiber isn’t directly digested like many nutrients (e.g., carbohydrates, proteins, and fats). Instead, it traverses the intestines, nourishing the beneficial microorganisms in the colon.
Moreover, as fiber moves through your digestive system, it helps you feel fuller. It increases the bulk of food, slows gastric emptying, and activates stomach muscles, sending more satiety signals to the brain.
The nutrients consumed also influence how energy is extracted from food. When carbohydrates are paired with fiber, sugar enters the bloodstream more gradually, stabilizing blood sugar and energy levels.
This ultimately impacts our appetite. Research conducted in 2021 showed that meals with higher dietary fiber lead to lower hunger levels and calorie intake throughout the day.

A similar trend is observed even when blood sugar levels are not assessed. Studies show that after consuming a fiber-rich breakfast—such as porridge or whole wheat bread—individuals report feeling fuller compared to alternative meals with lower fiber content but the same caloric value.
Thus, a healthy breakfast doesn’t only influence your morning; it creates lasting effects throughout the day.

Ease Digestive Health
Still unsure? There’s more good news. The fiber in your breakfast can also facilitate a healthy bowel movement in the morning.
This remains true regardless of when you consume it.
According to Harvard Gastroenterologist Dr. Trisha Pasricha, author of You’re Doing Poop All Wrong, one of the best ways to improve bowel health is by increasing fiber intake. “A softer, easier, and less strained bowel movement signifies that you are meeting your fiber goals.”
Fiber also helps support the gut’s natural circadian rhythm, providing particular benefits in the morning.
Dr. Pasricha explains that during sleep, your colon is relatively inactive. When you awaken, environmental cues activate the colon. “The first couple of hours after waking is when your colon is most active,” she notes.

This activity includes subtle contractions that push waste toward expulsion. A nutritious, fiber-filled breakfast can stimulate this natural process, leading to satisfying bowel movements without straining.
“The quality of your morning bowel movement can greatly influence your entire day,” Dr. Pasricha asserts. “I stand by this belief.”
Research supports this, with 153 adults reporting improved gut health in just two weeks after consuming a high-fiber wheat bran breakfast; participants noted increased energy, reduced bloating, and fewer sluggish feelings due to the addition of just 5.4 grams of fiber.
Reach Your Fiber Goals
Transitioning to a high-fiber breakfast is not only effective but also quite manageable.
Unlike lunch and dinner, we often repeat the same breakfast daily, making simple swaps impactful for overall dietary changes.
“Breakfast is a crucial opportunity to replenish your fiber intake,” Leeming emphasizes. “Skipping breakfast makes it difficult to meet your fiber needs.”
That said, it’s essential not to focus solely on breakfast. Both adults in England and the US consume just over half of the recommended 30 grams (1 oz) of fiber daily.

In this challenging scenario, breakfast alone is unlikely to resolve the issue. Leeming cautions that dramatically increasing fiber intake at breakfast without moderating lunch or dinner consumption may not be ideal for digestion.
“Your gut needs time to acclimate to fiber, so it’s best to spread your intake throughout the day,” she explains. “This acts like rocket fuel for your gut microbiome; spreading it out reduces unpleasant symptoms.”
To minimize bloating and discomfort, introducing more fiber gradually is key. Remember, every small increment helps.
“Even adding a mere 7 grams of fiber daily can significantly reduce your risks of heart disease, colon cancer, and type 2 diabetes,” she adds.
Since many breakfast foods are inherently high in fiber, it might be easier to prioritize your morning meal first.
For instance, swap cornflakes for whole-grain cereals, or replace white toast with seeded rye bread. Alternatively, enhance your porridge, overnight oats, Greek yogurt, or kefir with fiber-rich toppings like nut butters, seeds, and berries.
Consuming these modifications daily can greatly improve your health.

Recent research suggests that some microorganisms in the 5,300-year-old remains of Ötzi the Iceman may be metabolically active, despite his long-term ice preservation.
Ötzi’s mummified remains were discovered in 1991, as they melted from a glacier in the Alps near the Austria-Italy border. He is estimated to have lived between 3350 and 3120 BC. Over the last 35 years, studies of his remains revealed significant insights, including his probable dark complexion and baldness, and the fact that he had numerous tattoos. An arrow wound in his shoulder indicates he was murdered.
Ötzi is currently housed at the South Tyrol Archaeological Museum in Bolzano, Italy, under conditions that replicate those of his original icy environment: -6°C (21°F) with 99% relative humidity.
Researchers, including Frank Meixner from the Eulac Institute Mummy Research Institute, analyzed skin swabs, tissue fragments, and thawed water samples from Ötzi, collected in 1992, 2010, and 2019. They compared these to soil and ice samples from the discovery site in the 1990s.
Both ancient and modern microorganisms have been identified in Ötzi, with some possibly remaining metabolically active. “We can differentiate between Ötzi’s endogenous gut bacteria and those that entered his body from the environment after death,” Meixner explains.
Metagenomic analysis of internal tissues conducted by the research team has revealed specialized bacteria that thrive in mammalian intestines without oxygen, such as Treponema and Kineotrix. The extent of DNA damage in these bacteria suggests they were living in Ötzi’s body during his lifetime.
The diverse range of microbes found in Ötzi’s gut may reflect the varied diets of Chalcolithic humans, contrasting with those of modern Western societies, according to Meixner.
Additionally, the samples contained bacteria from the Pseudomonas genus, commonly found in soil and water. The DNA damage observed indicates these bacteria likely belong to an ancient microbial community at the discovery site.
The research team identified cold-tolerant or psychrophilic yeasts in Ötzi’s external samples: Phenoripheria, Graciojima, Gofojima, and Murakia.
Analysis indicated that these yeasts are also ancient microorganisms. Notably, the presence of Graciojima increased from 2010 to 2019, suggesting it may be metabolically active or capable of reproduction under current storage conditions.

“This is compelling evidence that Graciojima has colonized the mummy post-mortem,” states Nikolai Oskolkov, although he’d like additional data points to ensure results are not influenced by experimental conditions.
The increasing prevalence of yeast is intriguing, as noted by Damra Kaptan from the University of Stavanger, Norway. “Determining if it’s active will require us to check for RNA produced from the yeast DNA,” she elaborates. “It’s possible the yeast was dormant or partially activated during thawing.”
Some yeasts possess enzymes capable of breaking down proteins and collagen, which could potentially harm the mummies; however, researchers found no evidence of such damage.
The research team also identified microorganisms containing genes that can degrade the toxic compound phenol. Professor Meixner suggests this may be linked to treatments applied to the mummy in the 1990s aimed at controlling mold growth. “When Ötzi was discovered, there was already active mold, and he was treated with phenol,” he explains. “This could have strengthened the microbiome.”
Overall, the study indicates that Ötzi is not merely a biological time capsule, but rather a complex ecosystem formed from the inheritance of his gut microbes, the glacial environment, and over 30 years of preservation. “Given these microbes have been associated with the mummy from the start, should we consider them as part of his biological makeup?” questions Meixner.
He recommends ongoing genomic monitoring, including checks for activity signs like RNA and metabolites, to determine if the microbial community is awakening and affecting Ötzi’s tissue. If this occurs, scientists may need to reassess storage conditions to mitigate microbial activity.
Astronomers have unveiled compelling evidence that magnetic fields significantly influence weather patterns on exoplanets by analyzing the intense winds in the atmospheres of seven superhot Jupiters.

The Earth’s magnetic field plays a crucial role in atmospheric dynamics and is vital for maintaining conditions suitable for life.
Additionally, magnetic fields are present on other planets in our solar system, such as Jupiter and Saturn.
However, for the past 15 years, measuring the strength of an exoplanet’s magnetic field directly has remained a challenge.
“This breakthrough opens a new frontier in exoplanet science,” said Dr. Julia Seidel, an astronomer at the Lagrangian Laboratory at the Côte d’Azur Observatory.
“For the first time, we can compare the magnetic environments of distant worlds, a crucial step toward understanding which planets can support water and potentially host life as we know it.”
The research team gauged wind speeds on seven tidally locked superhot Jupiters orbiting various stars.
Measured wind speeds ranged from about 7,200 km/h to over 25,000 km/h—much faster than the maximum wind speed of approximately 1,500 km/h recorded on Jupiter.
Using data collected from the ESPRESSO instrument on ESO’s Very Large Telescope and a similar tool on the Gemini North telescope, the scientists uncovered a surprising trend: wind speeds decreased as planetary temperatures increased.
“This observation is counterintuitive, as hotter planets should theoretically have more energy to accelerate winds,” noted Professor Vivienne Parmentier from the Lagrangian Laboratory at the Côte d’Azur Observatory.
“Something must account for the reduced wind speeds on these hotter planets.”
The researchers deduced that the presence of a planet-wide magnetic field is the most plausible explanation. These magnetic fields can act as brakes, moderating the movement of charged particles within the atmosphere.
From their findings, the authors inferred the magnetic field strength of each studied planet, discovering that their intensities were comparable to those found in our solar system—approximately four times stronger than Saturn’s or about half of Jupiter’s strength.
Such formidable magnetic fields influence more than just the winds on these distant worlds.
“On Earth, we experience the beauty of the Northern and Southern Lights. Solar particles interact with magnetic fields, guiding them to the poles where they collide with atmospheric gases, creating a captivating display of colors,” explained Dr. Viviana Prinos from ESO.
“Magnetically driven auroras on these exoplanets could be even more breathtaking.”
This groundbreaking study was published in today’s issue of Nature Astronomy.
