Image of Sagittarius A*, the black hole at the center of the Milky Way galaxy
EHT
At the core of our Galaxy lies an extraordinary rotating entity: a black hole that appears to be spinning near its maximum velocity.
Michael Jansen from Radboud University in the Netherlands and his team investigated black holes in the center of the Milky Way, specifically Sagittarius A*, utilizing data gathered by a collective network known as the Event Horizon Telescope (EHT). To tackle the intricacies of the data, they opted for artificial intelligence methods.
Initially, they simulated approximately one million black holes using established mathematical models, a computational endeavor that necessitated millions of hours on supercomputers. These simulations served as training data for a type of AI known as neural networks, enabling them to assess the properties of black holes based on empirical observations. Subsequently, they fed the AI with data on Sagittarius A* collected by the EHT throughout 2017.
The AI determined that Sagittarius A* is rotating at 80-90% of its theoretical maximum speed. It also indicated to the researchers that none of the currently available magnetic field models adequately describe the characteristics of this black hole, highlighting the need for additional mathematical modeling. Janssen notes that earlier studies had merely narrowed down the potential characteristics of Sagittarius A*, such as its rotation speed and surrounding magnetic fields, while this new methodology has refined those estimates.
Dimitrios Psaltis from Georgia Tech in Atlanta remarked that some of the findings were unexpectedly counterintuitive. Previous analyses had not clarified whether black hole spins could be accurately discerned from EHT data.
While earlier research suggested that Sagittarius A* might be spinning at significant speeds, Mizuno Yuishi from Zhejiang University in Shanghai, China, noted that there is still room for enhancement in the computational models applied in this new analysis. “Our theoretical model is still not perfect,” he acknowledged.
However, both Mizuno and Psaltis agree that integrating AI into the study of exotic cosmic entities like black holes is increasingly essential. “We possess a wealth of data and numerous models, and we require a contemporary approach to merge the two,” Psaltis states. “This is precisely where machine learning proves to be transformative.”
Yet, this integration presents unique challenges, as AI work necessitates verification to mitigate potential inaccuracies and errors in subsequent analysis.
Janssen and his team have conducted numerous verification checks, including testing the AI with specially designed simulation data. They are also evaluating data from subsequent EHT operations and will be analyzing new findings from observatory results, he explains.
Excavation rigs often stir curiosity in fields dotted with grazing cattle. Although we are in Kansas, these rigs proudly display both American and Australian flags, indicating the origins of their owner. Hyterra, an Australian company, has been exploring for natural hydrogen fuels lurking in deep fractures of North America.
“I believe behind us is the kitchen where hydrogen is produced,” said Avon McIntyre, the company’s executive director. The surge in activity has drawn numerous businesses to the Midwest, positioning eastern Kansas as a pivotal area in the global quest for “geological hydrogen.”
This tale began about 1.3 billion years ago when the continent that is now North America began to fragment into two parts. While the continent eventually stopped separating, the fracture left a 2,000-kilometer-long mark of iron-rich mantle rock. Presently, this cleft lies buried beneath farms and ranches in the Midwest.
In eastern Kansas, older oil and gas wells have recorded high concentrations of hydrogen as solid rocks surrounding these fractures are pushed near the surface. To explore potential harvesting, several companies have secured hydrogen drilling rights over more than 100,000 hectares in the region, according to McIntyre’s analysis of public court documents. Hyterra and its competitor Koloma are advancing their efforts by drilling deeper into the earth.
“It’s like a gold rush, with everyone eager to find it,” stated Kristen Delano from the Colorado-based company Coloma. While she refrained from disclosing their drilling locations in Kansas, she noted that public opinion has indicated their recent excavations. Additional companies, such as the Australian firm Top End Energy, are acquiring mineral rights based solely on where Koloma is active.
“There has been considerable discussion within the community,” remarked Shawn McIntyre, who has no relation to Hyterra’s executive director. As a rancher from Waterville, Kansas, he has leased thousands of acres for hydrogen drilling. “This could revitalize the industry in small towns that have suffered economically in this region.”
The global pursuit of underground hydrogen escalated following updated assessments of global reserves several years ago. Companies investigating gas deposits are hopeful that it could become an alternative to the fossil fuels currently dominating heavy industry, fertilizer production, and electricity generation. “Natural hydrogen fits seamlessly into that narrative,” stated Jay Calbus from the Kansas Geological Survey. “If we are sitting atop a substantial supply of hydrogen that can be harnessed… it could transform not only the state but also the wider region, and the nation.”
As Avon McIntyre and I traverse the muddy terrain to the drilling platform southwest of Manhattan, Kansas, he shouts above the din of the rig, “It’s crucial to understand what’s happening down there.”
The company hypothesizes that water from the underground aquifer interacts with iron-rich mantle rocks within the Middle Continent fractures, resulting in the production of hydrogen through a process known as meandering. This reaction generates hydrogen molecules in the water, which subsequently migrate to the surrounding rocks.
This year, plans include drilling five exploratory wells aimed at identifying hydrogen concentrations along subsurface rises in bedrock known as Nemahalridge. Earlier reports revealed that the first well, drilled at a prominent location on this ridge, recorded hydrogen concentrations of 96%.
Currently, the second well is deepening, surpassing 1600 meters and operating continuously. At the rig, workers sift through the mud, which contains granite scraps from the excavated hole, extracting gas from the liquid for analysis.
In the Mud Shack, a makeshift office at the site’s periphery, a team of contractors monitors and reports in real-time the gas composition from varying depths of the well. While gas levels remained low in solid rock, hydrogen concentrations began measuring over 800 parts per million.
“[The first well] had an impressive peak, but this one is continuously producing hydrogen,” noted Hyterra’s Josh Whitcom.
While these measurements alone carry limited meaning, more precise evaluations require gas samples sent from the site. Moreover, high hydrogen concentrations do not indicate how much gas can actually be extracted or the duration of flow.
Even if hydrogen ultimately flows from any of these wells, numerous questions remain, such as how it will be isolated from other gases, transported, stored, and who will be its consumers.
However, McIntyre is thrilled by the detection of hydrogen and encourages the crew to work through the night. “Our goal is to gather information,” he stated. “And now we have some.”
On Monday, a federal judge in Boston ruled that the termination of grants from the National Institutes of Health signals the end of efforts aimed at diversity-related research topics. Trump’s administration has claimed this decision was “invalid and illegal,” citing discrimination against racial minorities and the LGBTQ community.
US District Judge William Young stated in a non-judicial trial that the NIH breached federal law by capriciously canceling over $1 billion in research grants linked to diversity, equity, and inclusion initiatives.
Judge Young indicated he is reinstating grants awarded to organizations that advocated for such initiatives in democratically led states. He also mentioned that as the case unfolds, more significant decisions might follow.
“This amounts to racism and discrimination against the American LGBTQ community,” remarked Young, a Republican appointee of President Ronald Reagan. “Government discrimination is profoundly wrong; I urge the court to prohibit it, and I will take action in due course.”
Discussing the end of grants for research addressing racial minority issues, Young expressed from the bench that he has “never witnessed such blatant racism” in his 40 years on the bench.
“You judge people of color based on their skin,” he stated concerning the Trump administration. “The Constitution does not permit that.”
The Department of Health and Human Services, representing the NIH and its parent organization, has not responded promptly to requests for statements.
Rachel Meelopol from the American Civil Liberties Union, who represents the grant recipients in the lawsuit, mentioned that Young’s ruling impacts hundreds of grants. The plaintiffs include the American Public Health Association and 16 states led by Massachusetts.
The NIH, the world’s premier funder of biomedical and behavioral research, has terminated approximately 2,100 research grants worth about $9.5 billion and an additional $2.6 billion in contracts since President Donald Trump took office in January. I signed on to protest the cuts last week.
These funding cuts reflect Trump’s broader agenda to reshape the government, reduce federal expenditures, and eliminate support for DEI programs and transgender healthcare. Another federal judge has temporarily blocked the administration’s plan to reduce 10,000 jobs across the NIH and other health agencies.
Trump has also enacted a series of executive orders mandating that institutions ensure grant funding does not support “gender ideology” and puts an end to what the administration deems “discriminatory” DEI programs. Conservative critics argue that these DEI initiatives unfairly target white individuals and others.
Aligned with Trump’s policy objectives, the NIH has directed staff to cease grant funding for research on DEI programs, issues facing transgender individuals, COVID-19 vaccine hesitancy, and funding beneficial to universities in China.
The trial presided over by Young on Monday focused on just a portion of the claims in the consolidated litigation regarding the funding cuts. He intends to consider additional claims later.
Young indicated he would allow political parties to present further evidence before making decisions regarding these claims and determine whether to restore grants beyond those allocated to the plaintiffs.
The cessation of NIH grants, coupled with delays in grant approvals and renewals, has reverberated across universities nationwide, many of which now face the loss of significant portions of their research budgets.
As a result, universities have initiated employment freezes, travel restrictions, reduced class sizes, furloughs, and layoffs.
Numerous universities depend on NIH grants for the majority of their research funding. For instance, Washington University, recognized as the top public institution for biomedical research, reported receiving roughly 1,220 grants from the NIH, totaling about $648 million last year, as per court documents.
Students and faculty at universities have expressed concerns that the funding confusion could lead to brain drain from the United States, as researchers increasingly seek positions abroad. This slowdown also threatens long-term research initiatives, including projects focused on banking and studying the brains of Alzheimer’s patients.
The Trump administration has aimed to reduce other critical research funding sources.
In February, US District Judge Angel Kelly halted regulations that severely restricted government payments for indirect research costs, including equipment, maintenance, utilities, and support staffing. The administration projected that this action would eliminate $4 billion in funding for research institutions.
Reading various novels for work can sometimes be challenging, especially when you want to find something captivating. However, Time Saving by Kaliane Bradley instantly drew me in with its engaging prologue. It was a brief glimpse into the life of a man sprinting through the snow, hearing his ship signal him. This offered plenty of intrigue for what was to come.
This month’s selection for the New Scientist Book Club has been a resounding success since its release last year. The narrative follows a young civil servant who unexpectedly applies for a mysterious position involving time travel, a concept kept under wraps, allowing individuals from the past to journey to the present.
These “visitors” require support, which is where our unnamed heroine comes in as a caretaker, dubbed a “bridge.” She is assigned to Commander Graham Gore, living with him and assisting him in adjusting to modern life.

This is not solely a narrative about time travel; it meticulously explores whether the government would permit time travelers to integrate into society alongside civil servants. The novel confidently posits that, for this reader, it could have crafted Sally without delving into excessive particulars.
One of the intriguing aspects of the story is that Gore is rooted in reality, having been a genuine figure that many remain unaware of. He was the first officer of John Franklin’s ill-fated expedition to the Arctic and met his demise around 1847 or 1848. While the specifics of his final hours remain uncertain, the novel takes a creative approach by transporting him to contemporary London just before his death.
Modern London is full of men from the lost world. But Gore is a resilient and capable officer.
Bradley’s depiction of Gore exemplifies the art of storytelling. She brings him to life with such precision that he appears as a tangible, charismatic individual—rarely do we encounter characters so vividly portrayed in literature.
The vibrant interaction between our young bureaucrat and this spirited officer of the Colonial Royal Navy unfolds within the context of a future version of London, where many individuals from the past now inhabit. Once again, Gore’s resilience shines, highlighting that he is adaptable, making for the most enjoyable segments of the narrative where they learn from one another.
The plot transitions from romance to thriller, composing about 40% sci-fi, 40% romantic comedy, and 20% thriller. I found the initial segment significantly more engaging, though I questioned whether the thriller conclusion would hold up. However, this does not overshadow the fact that the book offers a delightful reading experience, perfect for those looking for fun.
At the conclusion of the novel, Bradley includes a photograph of Gore. Having grown fond of his fictional counterpart, it was a poignant moment to connect with the real historical figure. According to Bradley’s PostScript, he was regarded as “a remarkably fine officer with a kind temperament.”
This beloved, memorable officer represents a captivating twist in history that deserves a place in a bestselling novel nearly two centuries later. Bradley has undoubtedly fashioned a most endearing hero.

Are these vacationers experiencing “seasonal body image dissatisfaction”?
Shutterstock/Puyalroyo
While winter still lingers in the Northern Hemisphere, we’re nearing the summer solstice. The sun overhead signifies one thing: a surge of lifestyle articles and social media posts encouraging you to “get your beach body ready.”
A friend of mine recently shared his anxiety about summer for this exact reason. “I’ve even stopped trying to get a six-pack,” he confessed. “But I feel really self-conscious without my shirt on.”
This conversation piqued my curiosity about whether this sentiment is widespread. I soon discovered several recent studies addressing “Seasonal Body Image Dissatisfaction,” along with strategies to combat it.
Scott Griffith and his team at the University of Melbourne conducted a groundbreaking study involving 823 gay and bisexual men globally. They found that over 70% reported significant physical dissatisfaction during summer, more so than in any other season, attributing it to societal pressures from the media and the increased exposure of their bodies.
These findings align with a recent analysis of 12 million social media posts from 2020 to 2023, revealing that expressions of self-loathing peaked in July, with similar trends noted for December in both hemispheres.
If any of this resonates with you, it may be beneficial to explore research on mindful self-compassion. This concept emphasizes three core aspects: recognizing that one’s struggles are universal, developing a mindful awareness of our experiences, and refraining from getting lost in negative thoughts and emotions.
Personally, I would love to see a rise in “body-neutral movements” on social media. Unlike “body-positive exercise,” which aims to celebrate our flaws, body neutrality prioritizes bodily function over appearance.
Forthcoming research by Raeanna Kilby and Kristin Mickelson of Arizona State University suggests that body neutrality may more effectively decrease self-objectification compared to body positivity. Jameela Jamil advocates for this perspective, stating, “My body is not an advertising board for others. It’s not something for them to judge, nor for me to judge… I focus on enjoying life to the fullest.”
This summer, my goals are centered on health, happiness, and friendships—the true #gains.

The sun’s corona appears as it would to the human eye during a solar eclipse, but through a green filter.
ESA/proba-3/aspiics
The synchronized movement of the twin satellites has produced the first artificial solar eclipse in space, revealing the burnt corona of the sun in remarkable detail.
The ProBA-3 mission, launched last December, is operated by the European Space Agency (ESA) and consists of two satellites positioned 150 meters apart.
One of the satellites, known as Occulter, features 1.4-meter wide discs made from carbon fiber and plastic, effectively blocking sunlight coming from the second satellite, Coronagraph. The alignment accuracy of the satellites is within one millimeter for capturing images.
In March, the satellites autonomously synchronized for extended periods, providing lengthy exposures of the solar eclipse. ESA scientists can stitch these exposures together to generate a comprehensive image of the solar corona, the outermost layer of the sun’s atmosphere.
“When I first viewed these images, it was unbelievable,” says Damien Galano from ESA. “But shortly after, it transformed into an incredible sense of achievement and pride for all our hard work.”
The image above captures the visible light of the corona, resembling how it would appear to the human eye but through a green filter.
This image illustrates the light emitted from electron-depleted iron in the most heated sections of the corona.
ESA/proba-3/aspiics
The Proba-3 satellite camera also captures light frequencies linked to specific elements within the solar corona, exemplified by the dark green image above.
“We can clearly see the substantial achievements made during COVID,” remarks Galano.
The sun’s corona shown in polarized white light, artificially tinted to look violet.
ESA/proba-3/aspiics
The image above illustrates the sun’s corona, artificially colored purple in polarized white light. This technique allows scientists to distinguish the polarized light from the hot corona from that scattered by interplanetary dust.
These images were primarily captured to verify the ProBA-3 mission’s functionality. When fully operational, they will take pictures of the artificial food every 19.6 hours.
This will enhance our comprehension of solar corona physics, and according to Galano, it will also improve understanding of solar winds and coronal mass ejections that influence space weather.

The previous CEO of 23andMe is poised to reclaim leadership of the genetic testing firm after placing a $305 million bid from the nonprofit organization.
Recently, Regeneron Pharmaceuticals announced a deal to purchase the company for $256 million, surpassing a $146 million offer from Anne Wojcicki and the nonprofit TTAM Research Institute. A former executive noted that this substantial offer prompted Wojcicki to elevate her bid with backing from the Fortune 500 entity. The deal is anticipated to finalize in the upcoming weeks, pending a court hearing scheduled for June 17, as stated by the company on Friday.
Wojcicki had made several attempts while CEO to retain the company as private. Each attempt was met with rejection from the board, and ultimately all independent directors resigned in response to her acquisition efforts.
As a leader in ancestral DNA testing, 23andMe filed for bankruptcy in March and aimed to auction its business following a 2023 data breach that compromised sensitive genetic and personal information of millions of users.
Since its bankruptcy announcement, 23andMe has seen a significant loss of clients, with a concerning trend of users wanting their accounts closed. The company, which analyzes complete genomes with unknown parties showing interest, reported that approximately 15% of its current customers are requesting account terminations in light of the bankruptcy and potential sale. Experts recommend that customers ask firms to delete their DNA data to safeguard privacy. On Friday, TTAM endorsed 23andMe’s existing privacy policy, asserting compliance with all relevant data protection regulations. Earlier this week, New York and over 20 other U.S. states filed a lawsuit against 23andMe to contest the sale of personal data from its clients.
Regeneron expressed enthusiasm for the new bid, but acknowledged that if Wojcicki’s offer were ultimately accepted, it would incur a $10 million termination fee.
A recent study conducted by researchers at the University of Chicago School of Medicine and Columbia University revealed that increasing fruit and vegetable intake to five cups daily, as recommended by dietary guidelines, is linked to a 16% enhancement in sleep quality.
Borge et al. Increasing fruit and vegetable intake during the day was found to be associated with improved sleep that same night. Image credit: Guillermo Gavilla.
Observational studies have shown that diets of high quality correlate with better sleep quality.
Despite this, a deeper comprehension of this relationship is essential, as dietary changes could represent novel and natural methods for enhancing sleep.
“We have been striving to maximize our lives,” stated Dr. Esla Tasari, director of the Sleep Center at the University of Chicago.
“The temporal associations and objectively measured outcomes from this study are significant in addressing gaps in crucial public health knowledge.”
Earlier observational research indicated that higher consumption of fruits and vegetables was connected to improved self-reported overall sleep quality, but this latest study is the first to establish a temporal link between specific daily food choices and objectively measured sleep quality.
Healthy young adults in this study recorded their daily food intake through an app and wore wrist monitors to allow researchers to obtain objective measurements of their sleep patterns.
The researchers focused on sleep fragmentation, which indicates the frequency of awakenings during sleep or transitions into deep sleep throughout the night.
They discovered that meal choices had significant correlations with differences in sleep quality the following night.
Participants consuming more fruits and vegetables during the day experienced deeper, more uninterrupted sleep that night, similar to those who included healthy carbohydrates like whole grains.
Based on their findings and statistical modeling, scientists estimate that those who adhere to the CDC’s recommendation of five cups of fruits and vegetables per day could see a 16% improvement in sleep quality compared to those who do not consume these foods.
“A 16% difference is substantial,” said Dr. Tasari.
“It’s remarkable that such significant changes can be detected within just 24 hours.”
Future studies will aim to establish causal relationships, expand the findings to diverse populations, and explore the underlying mechanisms of digestion, neurology, and metabolism that may clarify the positive effects of fruits and vegetables on sleep quality.
Nevertheless, based on current evidence, the authors strongly recommend maintaining a diet rich in complex carbohydrates, fruits, and vegetables for optimal long-term sleep health.
“They are making a difference,” remarked Dr. Marie Pierre St. Onge, director of the Center for Sleep and Circadian Research at Columbia University Irving Medical Center.
“Minor adjustments can impact your sleep. It’s empowering to know better rest is within your control.”
The study was published in the journal Sleep Health this month.

The UK’s Intelligence Commission (ICO) has urged manufacturers of air fryers, smart speakers, fertility trackers, and smart TVs to prioritize the privacy rights of individuals.
Many individuals feel overwhelmed by the lack of control over how data is gathered, utilized, and shared regarding their homes and personal lives.
Following concerns raised about an air fryer that reportedly listens to its environment, Public concerns have emerged about digital devices collecting an excessive amount of personal data, prompting data protection regulators to issue initial guidelines on the handling of personal information.
Manufacturers and data handlers are now required to ensure data security, maintain transparency with consumers, and routinely delete collected information.
“We are pleased to share our commitment to offering a diverse range of services to our clients,” stated Stephen Almond, executive director of ICO’s regulatory risks.
“These products are meant to enhance our lives, but that doesn’t imply they should collect unnecessary data… Users shouldn’t have to sacrifice their privacy to enjoy the advantages of smart devices.”
“Everyone expects a degree of privacy within their own homes, thus we need to trust that smart products will honor that privacy, act responsibly, and utilize information only as anticipated.”
The new guidance points out various devices classified as part of the “Internet of Things,” which collect data that must be managed with care. These items include smart fertility trackers that log user periods and temperature readings, transmitting that data back to manufacturer servers to determine fertile days.
Smart speakers should not only listen to their owners but also to other family members and visitors; they must be designed to empower users to adjust settings to minimize personal data collection.
Regulators emphasized that manufacturers must be clear with individuals regarding the use of their personal data, only collecting what is necessary, and enabling easy deletion of data from devices.
The ICO has stated to manufacturers that it is “prepared to take necessary actions to safeguard individuals from potential harm.”
Astronomers utilizing the NASA/ESA Hubble Space Telescope have captured remarkable new images of the Dwarf Starburst Galaxy NGC 4449.
This Hubble image illustrates NGC 4449, a galaxy of dwarf stars located roughly 12.5 million light years away within the Canes constellation. Image credits: NASA/ESA/Hubble/E. Sabbi/D. Calzetti/A. Aloisi.
NGC 4449 is situated about 12.5 million light years away in the constellation of Canes.
Also known as Caldwell 21, Leda 40973, or UGC 7592, this galaxy is approximately 20,000 light-years in age.
NGC 4449 was first identified by German-born British astronomer William Herschel on April 27, 1788.
This galaxy is part of the M94 Galaxy group and is in close proximity to the local group that contains our Milky Way.
“NGC 4449 is a dwarf galaxy, meaning it is significantly smaller than our Milky Way and contains fewer stars,” a Hubble astronomer remarked.
“However, its small size is deceptive; NGC 4449 is prolific in star formation.”
“This galaxy is referred to as a Starburst galaxy because it produces new stars at a rate much higher than would be expected for its size.”
“While most Starburst Galaxies primarily produce stars in their centers, NGC 4449 is scattered with bright young stars throughout its structure.”
Astronomers believe this global surge in star formation has resulted from interactions between NGC 4449 and its neighboring galaxies.
“Due to its proximity, NGC 4449 offers a valuable opportunity for Hubble to investigate how intergalactic interactions influence new star formation,” they noted.
The new color image of NGC 4449 is derived from Hubble observations utilizing the Advanced Cameras for Surveys (ACS) and the Widefield Camera 3 (WFC3) across the UV, near-infrared, and optical segments of the spectrum.
Seven filters were employed to capture various wavelengths, assigning different hues to each monochrome image linked to the specific filters.
“The Hubble images of NGC 4449 were previously released in 2007,” the researchers stated.
“This updated version includes several additional wavelengths of light gathered by Hubble through multiple observational programs.”
“These programs encompass groundbreaking science, ranging from exploring the history of star formation in NGC 4449 to mapping galaxies with the brightest, hottest, and most extensive stellar structures.”
Methane penetration refers to a submersible area around the globe where the natural gas you rely on for cooking and heating is known as methane that leaks from the seabed. These penetrations are commonly found in transitional regions where land meets the ocean, known as the continental margin. Methane originates from and is produced by organic matter, including dead plants and animals, that have been buried under layers of sediment for millions of years. Through pressure and heat from within the Earth, this organic matter can decompose into methane, which escapes from the seabed into the ocean.
This methane also serves as an energy source for various microscopic organisms, allowing it to fuel your stove. The microorganisms known as methanogenic bacteria or methanotrophs utilize methane as food through a process referred to as aerobic methane oxidation. These bacteria employ oxygen to extract energy from methane gas, akin to how humans extract energy from food, producing carbon dioxide and water as by-products.
When carbon dioxide interacts with water, it creates a weak acid known as carbonic acid. Carboxylic acids can dissolve calcium carbonate minerals that make up shells in organisms like corals, mussels, and clams. While methanotrophs produce carbon dioxide as waste, scientists remain uncertain about its role in corroding calcium carbonate in marine environments. Research has been conducted in laboratories, but not in natural marine settings until now.
A team of researchers from Germany investigated the corrosion of calcium carbonate associated with active methane along the continental margin off the west coast of Gabon, Congo, and Angola in Africa. They deployed limestone cubes measuring 10 cm (around 4 inches) high and 4 cm (approximately 4 inches) wide above the seabed near active methane sites, as well as on a mussel bed. The cubes were left on the seabed for 2.5 years before being retrieved.
Upon recovery, the researchers noted that cubes situated near the methane leak exhibited rough surfaces. Microscopic examination revealed small holes, termed microborings, likely created by microorganisms. In contrast, cubes placed farther from the methane leak showed no signs of such features. This led researchers to interpret these differences as evidence that microorganisms are responsible for the dissolution of limestone in areas of methane penetration.
To further analyze the role of methanotrophs in limestone dissolution, the team extracted DNA from microbial communities inhabiting the limestone cubes. They identified DNA from members of aerobic methane-oxidizing bacteria, particularly from the uncultured HYD24-01 clade. Previous studies have detected these microorganisms in other methane-rich locations, suggesting their potential for corroding limestone.
To corroborate their findings, the researchers also examined lipid molecules known as lipid biomarkers from microorganisms at the site. Scientists utilize lipid biomarkers to identify bacterial species and their energy sources. They discovered that the lipid biomarkers collected from the seabed sites matched the DNA results. Notably, they found an abundance of lipids from methanotrophs called NC16:1Ω7 among the limestone cubes. This led them to conclude that methanotrophs prominently represented the microbial communities linked to the microborings in the limestone.
The research team proposed that their findings provide concrete evidence that methane-consuming bacteria dissolve calcium carbonate rocks in areas of marine methane. They suggested that these bacteria acidify their environment by releasing carbon dioxide during methane oxidation. The released carbon dioxide combines with water to form carbonic acid, which decreases pH levels, dissolves limestone, and contributes to ocean acidification. They advocated for future research to delve into the specific mechanisms that these microorganisms utilize and to quantify the extent of microbial erosion’s contribution to marine acidification.
The city’s renowned musicians may have claimed that love can’t be bought with money, but that was before Bitcoin came onto the scene.
Recently, Liverpool has been recognized as the UK’s cryptocurrency capital, based on a study evaluating online behaviors among citizens nationwide.
A survey by telecommunications provider OpenReach revealed that 13% of participants from Liverpool regularly invest in cryptocurrency and stocks, more frequently than any other region in the UK.
Several cities across the UK have emerged as hotspots for various activities. London is identified as the UK’s online dating hub, with 24% of respondents stating they have engaged with dating apps for at least three days.
In contrast, only 4% of the national respondents indicated that they spend time on dating applications according to this survey.
The survey suggests that the average British citizen dedicates 3.5 hours a day to the internet, but 20% confessed to spending more than five hours daily online.
Although online activity varies, 64% of participants reported being active from 11 PM to 6 AM, with 19% saying it’s time to visit YouTube.
In the North, the analysis highlights the digital habits of three cities. Manchester residents utilize Instagram more than anywhere else, with 27% of the population engaging with the platform regularly.
Meanwhile, Sheffield stands out as the leading city for both TikTok engagement and music streaming, with 32% and 30% of its residents participating, respectively. It also ranks as the city where households spend the most time online, with 32% admitting to exceeding five hours each day on the internet.
In Leeds, residents seem to favor the older social media platforms, with 43% spending a significant portion of their time on Facebook.
This research was commissioned by OpenReach to mark the anniversary of the first broadband installation in a British home, which took place in Basildon, Essex, in April 2000.
The findings revealed that many participants expressed dissatisfaction with their internet usage; 43% reported wasting time online, 37% were concerned about “doom scrolling,” and 33% stated they felt more relaxed when they reduced their online activity.
Katie Milligan, Associate CEO of OpenReach, commented:
“At the same time, we encourage many people to recognize the importance of taking time away from devices and digital connections.”
In recent years, the desire to establish human colonies beyond Earth, whether to escape environmental issues or explore uncharted territories, has gained significant traction.
While much attention is given to proposed bases on the Moon and Mars, there’s a more challenging and lesser-known frontier much closer to home: the ocean’s depths.
This concept isn’t new. Since the 1960s, with pioneers like French oceanographer Jacques Cousteau, individuals have created and spent extended periods in aquatic habitats.
NASA has been sending teams to the Aquarius Reef Base since 2001. This research facility, located 20 meters (around 65 feet) underwater off the Florida coast, has allowed scientists, engineers, and future astronauts to live in the module for 7 to 14 days.
With advancements in technology, prolonged underwater stays may become feasible. The UK company, Deep, is leveraging this technology to design habitats for extended underwater living. But, is the technology the only challenge we face?
Above the Atmosphere, Under the Sea
Humans are quite vulnerable. We struggle without oxygen or sunlight and are not fond of extreme pressure changes. Thus, we might not be the best candidates for life at the ocean floor.
This doesn’t imply that we can’t thrive in inhospitable environments.
Since 2000, astronauts have spent significant periods aboard the International Space Station (ISS).
Several astronauts have been documented living in the ISS for over 300 consecutive days, but Valeri Polyakov holds the record, having spent 437 days aboard the Mir Space Station in Russia between 1994 and 1995.
Moreover, astronauts returning from lengthy missions often face health issues, such as reduced bone density and muscle atrophy. What does this mean for those who aim to live underwater?
The most extensive study is that of Rudiger Koch, a German aerospace engineer who lived in a capsule submerged 11 meters (36 feet) under the Caribbean Sea for 120 days between 2024 and 2025.

In second place is Professor Joseph Dituri, who spent 100 days studying the physical and psychological effects of living underwater in a lodge situated at the bottom of a 9-meter deep (30-foot) lagoon in Florida.
Dituri conducted daily tests during his time submerged and following his return to the surface. Notably, aside from minor setbacks, he felt quite well.
He noted improvements in sleep quality, cholesterol levels, and inflammation. His stem cell count, testosterone levels, and cognitive performance also improved.
Interestingly, Dituri appeared to have lowered his biological age (an indicator of the aging process of the body), although he was recorded as having shrunk by over 1 cm (approximately 0.5 inches) due to the pressurized environment inside the lodge.

A Step Towards Living Underwater
With limited data, we still have a tenuous understanding of life in aquatic environments. This is where Deep comes in.
The ocean technology and exploration company aims to develop two habitats by 2027, with the goal of establishing a permanent underwater presence. They are using a submerged quarry in Gloucestershire as a testing ground for their underwater habitats.
Deep is developing two habitat models: Vanguard, designed for three-person short stays, and Sentinel, a 16-meter (52-foot) capsule intended as a long-term habitat complete with living quarters, bedrooms, and research facilities, capable of accommodating researchers at depths of up to 200 meters (656 feet) for 28 days.
The aim is to enable researchers to remain submerged for extended periods, allowing for comprehensive studies of underwater living impacts and marine life. However, achieving these depths poses significant challenges.
“The most hazardous aspects of diving occur during descent,” explains Dr. Dawn Kernagis, Deep’s scientific research director. “Divers breathe compressed gas, with fluctuating pressure increasing the risk of decompression sickness (DCS), where gas bubbles form in the bloodstream.”
While most DCS cases are mild, severe instances can impact the brain, spinal cord, respiratory system, and circulatory systems.
To mitigate these risks, Deep aims to keep researchers “saturated” in the Sentinel habitats. This means achieving a new equilibrium with the underwater environment.
“Saturated tanks, like ours, facilitate diving into greater depths and adjusting to the pressure, enabling much longer stays, ranging from hours to about a month,” states Kernagis.
Deep plans for close monitoring of researchers during their stays to better understand the long-term physical and psychological effects of deep-sea living.
The foundation laid now may support future inhabitants underwater for weeks, months, or even years. In the not-so-distant future, some of us may find ourselves living in a modern-day Atlantis.

In 2014, a team of researchers from Harvard and the University of Virginia invited participants to spend 15 minutes alone with their thoughts, with the only option for interaction being a button that delivered a painful electric shock. Almost half of the participants chose to press that button. One individual pressed it 190 times despite previously expressing a desire to avoid the shock. The study’s authors concluded that “people prefer thinking,” even when the alternative is discomfort. This might be because, when left to our own devices, our minds often wander to unwelcome thoughts.
Since the widespread use of smartphones, many have carrying the psychological equivalent of the electric shock button in their pockets. This device can quickly alleviate boredom, even though it may not be beneficial for us. During quiet or solitary moments, we often reach for our phones or use them to distract ourselves from unsettling late-night thoughts. Every time this occurs, it reinforces unhealthy patterns, making it easier to evade unwanted thoughts. It’s significant to note that most individuals become distracted through similar screen-based methods.
Smartphones amplify the expectation to use our time efficiently, pushing us to optimize every moment. For instance, if a commuter on a Harley Reed must look out the window or read a book on the train, they may check emails to avoid feelings of guilt and inefficiency. Doing nothing is often regarded as time wasted, disregarding the fact that during such moments, we engage in profound thinking. What becomes of the complex thoughts that arise right before we reach for our phones again?
Psychologists who specialize in boredom acknowledge its discomfort yet recognize its value. Similar to hunger and loneliness, it signals our need for change or novelty. Erin Westgate, a psychology professor at the University of Florida, explains that we feel bored when something fails to capture our attention or is deemed meaningless. However, this does not imply that engaging activities must always be significant. For example, while Sudoku is engaging, it lacks true meaning, unlike mundane tasks like watching paint dry.
When boredom strikes, it should ideally inspire us to pursue something more meaningful or captivating. If we fail to address our boredom or are unable to find something engaging, we risk slipping into chronic boredom. As noted in research, this condition is linked with various issues including depression, anxiety, life satisfaction, poor academic outcomes, substance abuse, and reckless behavior, among others.
Evidence indicates that persistent boredom is becoming increasingly prevalent, coinciding with the rise of smartphones. In a study published last year, researchers stated that the percentage of students in China and the US describing themselves as bored has steadily climbed since 2010. Why does digital media contribute to this trend? Research suggests that we often reach for our phones to alleviate boredom, yet this behavior can actually exacerbate it. For instance, one study revealed that those bored at work were more inclined to use their smartphones, leading to even greater boredom later on.
While checking your phone may address certain immediate needs when boredom arises, digital devices excel at capturing and retaining attention. Most online interactions are designed for engagement and monetization rather than meaningful connection. With the myriad of notifications and distractions, it’s all too easy to plan for just a quick five-minute check lasting two hours. The average American spends over 4 hours a day using their smartphones, accumulating to more than 7 hours of screen time daily. This translates to 17 years of life spent online as an adult—a reality that even the most ardent tech enthusiasts would likely view with concern.
The allure of mobile phones can quickly overshadow important messages we might need to contemplate, such as “Why am I feeling like this?” or “What do I truly need?” It’s essential to pause and ask ourselves these questions instead of being swayed by technology. When faced with boredom, we should resist the impulse for immediate relief and take time to reflect. Embracing boredom, even briefly, may paradoxically lead us to more meaningful and creative experiences in life.
oBlue UT You will receive a call or text offering you a job opportunity. It seems enticing – it’s remote work, and you can potentially earn £800 daily. If you’re interested, just reach out to the sender through the provided WhatsApp number.
The tasks are quite simple. Typically, you’re asked to engage with TikTok content through likes and shares.
“Once you start liking and sharing, you’ll get a small payout. However, this is fraudulent funding tied to individuals involved in scams,” remarks Annya Burskys, head of fraud prevention at the National Building Association. “Then, you might be told that you need to pay a total to unlock greater profits, which could be framed as a training fee.
“Part of that money is used to compensate other victims, leading some into organized crime syndicates.”
Burskys highlights that this initial outreach is particularly enticing for many, especially students.
“We’re noticing an uptick in incidents, particularly within the 16-25 age group,” she says. “Previously, we didn’t receive such reports daily, but now we hear from individuals who have sent money or from banks alerting us about funds transferred to these accounts.”
In some instances, the victim might inadvertently become a “money mule.”
Beyond sharing funds or account details, victims may later discover that their bank and identity information have been exploited for additional fraud.
Typically, victims incur losses amounting to hundreds or thousands of pounds. “It’s far from a good deal. The concern lies in the volume,” she explains. “Events unfold swiftly. From initiation to the realization that you’ve been scammed, an investment fraud can occur over mere months or even years.”
As academic institutions close for the summer, students seeking employment should be cautious of potential scams.
What does fraud look like?

Messages often claim to originate from recruitment agencies, sometimes using legitimate company names or stating availability of work through TikTok. Some texts even reference your CV as if you’d submitted it. They promise earnings of hundreds of pounds daily (the £800 figure is a recurring theme).
Calls may bear similarities too. In a recent week, an automated voice falsely claimed to represent a recruitment agency, instructing recipients to contact via WhatsApp if interested in the job. The associated phone number typically appears as a regular UK mobile.

What the message asks for
The initial message will prompt you to express interest in the position. The scammer will claim it involves work related to sharing content preferences (likely TikTok videos). When you register or when it’s time for payment, you may be asked for more personal information.
You might receive an initial “payment,” but then you will be requested to cover costs for training or to unlock access to higher earnings.
What to do
Be cautious of unsolicited messages that claim to offer job opportunities. This approach is not typical for genuine recruitment agencies. The agency asserts, “In fact, we don’t utilize our platform to directly contact job seekers for our employers to acquire new employees.”
Burskys recommends that if you receive messages from recruiters or companies offering jobs, investigate by “using the company’s home and researching on LinkedIn.” A company’s home page may provide insights into its operations, directors, and details regarding their legitimacy.
If you know the name of the employer, visit their site to see if the position is advertised.
In the UK, reports of fraudulent messages can be forwarded to 7726.
Numerous recruiters provide advice on safely conducting your job search, such as these tips.
In recent years, a substantial number of university students in the UK have been identified for misusing ChatGPT and similar AI tools. While traditional forms of plagiarism appear to be declining significantly, a Guardian investigation reveals concerning trends.
The investigation into academic integrity violations has indicated a rise to 5.1 cases per 1,000 students, with nearly 7,000 verified instances of fraud involving AI tools reported between 2023 and 2024. This marks an increase from just 1.6 cases per 1,000 students in the previous academic year, 2022-23.
Experts anticipate these figures will increase further this year, estimating potential cases could reach around 7.5 per 1,000 students, although reported cases likely reflect only a fraction of the actual instances.
This data underscores the rapidly changing landscape for universities as they strive to update evaluation methods in response to emerging technologies like ChatGPT and other AI-driven writing tools.
Before the advent of generative AI in the 2019-20 academic year, plagiarism accounted for nearly two-thirds of all academic misconduct. Plagiarism rates surged during the pandemic as many assessments transitioned online. However, with advances in AI tools, the character of academic fraud has evolved.
Predictions suggest that for the current academic year, confirmed instances of traditional plagiarism could decrease from 19 per 15.2 to 15.2, falling to approximately 8.5 per 1,000 students.
The Guardian reached out to 155 universities via the Freedom of Information Act, which mandates disclosure of confirmed cases of academic misconduct, including plagiarism and AI-related fraud over the past five years. Out of these, 131 responded; however, not all universities had comprehensive records of annual or fraud categories.
More than 27% of responding institutions did not categorize AI misuse as a distinct form of fraud in 2023-24, indicating a lack of acknowledgment of the issue within the sector.
Numerous instances of AI-related fraud may go undetected. A survey by the Institute for Higher Education Policy revealed that 88% of students admitted to utilizing AI for evaluations. Additionally, last year, researchers at the University of Reading tested their rating system and found that AI-generated submissions went undetected 94% of the time.
Dr. Peter Scarf, an associate professor of psychology at the University of Reading and co-author of the research, noted that while methods of cheating have existed for a long time, the education sector must adapt to the challenges posed by AI, creating a fundamentally different issue.
He remarked, “I believe the reality we see reflects merely the tip of the iceberg. AI detection operates differently from traditional plagiarism checks, making it almost impossible to prove misuse. If an AI detector indicates AI usage, it’s challenging to counter that claim.”
“We cannot merely transition all student assessments to in-person formats. Simultaneously, the sector must recognize that students are employing AI even if it goes unreported or unnoticed.”
Students keen to avoid AI detection have numerous online resources at their disposal. The Guardian found various TikTok videos that promote AI paraphrasing and essay writing tools tailored for students, which can circumvent typical university AI detection systems by effectively “humanizing” text produced by ChatGPT.
Dr. Thomas Lancaster, a researcher of academic integrity at Imperial College London, stated, “It’s exceedingly challenging to substantiate claims of AI misuse among students who are adept at manipulating the generated content.”
Harvey*, who has just completed his Business Management degree at Northern University, shared with the Guardian that he utilized AI for brainstorming ideas and structuring tasks while also incorporating references, noting that many of his peers have similarly engaged with these technologies.
“When I started university, ChatGPT was already available, making its presence constant in my experience,” he explained. “I don’t believe many students use AI simply to replicate text. Most see it as a tool for generating ideas and inspiration. Any content I derive from it, I thoroughly rework in my style.”
“I know people who, after using AI, enhance and adapt the output through various methods to make it sound human-authored.”
Amelia*, who has just completed her first year in a music business program at a university in the southwest, also acknowledged using AI for summarization and brainstorming, highlighting the tool’s significant benefits for students with learning difficulties. “A friend of mine uses AI for structuring essays rather than relying solely on it to write or study, integrating her own viewpoints and conducting some research. She has dyslexia.”
Science and Technology Secretary Peter Kyle recently emphasized to the Guardian the importance of leveraging AI to “level the playing field” for children with dyslexia.
It appears that technology companies see students as a key demographic for their AI solutions. Google is now providing free upgrades to university students in the US and Canada for 15 months to its Gemini Tools.
Lancaster stated, “Assessment methods at the university level may feel meaningless to students, even if educators have valid reasons for their structure. Understanding the reasons behind specific tasks and engaging students in the assessment design process is crucial.”
“There are frequent discussions about the merits of increasing the number of examinations instead of written assessments, yet the value of retaining knowledge through memorization diminishes yearly. Emphasis should be on fostering communication skills and interpersonal abilities—elements that are not easily replicable by AI and crucial for success in the workplace.”
A government spokesperson stated that over £187 million has been invested in the national skills program, with guidelines issued on AI utilization within schools.
They affirmed: “Generative AI has immense potential to revolutionize education, presenting exciting prospects for growth during transitional periods. However, integrating AI into education, learning, and assessment necessitates careful consideration, and universities must determine how to harness its advantages while mitigating risks to prepare for future employment.”
For bank leaders, it’s their worst nightmare. Urgent communications have rapidly unleashed turmoil across the UK’s financial sector, as cyberattacks incapacitate IT infrastructures.
Bank executives recognize that their stakes are particularly high, especially as family names in other sectors, like Marks & Spencer, grapple with the repercussions of such breaches.
Within hours of a bank breach, millions of direct debits might fail, jeopardizing rent, mortgages, and salaries. Online banking access may be blocked, cash withdrawals denied, and commuters stranded as buses and gas stations refuse payments. News of such an attack often incites panic, prompting rival banks to react and customers to withdraw their funds in anticipation of disruptions.
While this may seem extreme, a well-executed cyberattack on a major UK bank is not far removed from the government’s “rational worst-case scenario.” The financial sector, categorized as one of the 14 “critical national infrastructure” sectors, is particularly vulnerable. Highlighted in the National Risk Register, it models the most significant threats confronting the UK.
This spring, billions of pounds were invested to prevent catastrophic incidents involving major retailers like Harrods, The Co-op, and M&S.
“The financial commitment will be substantial,” Ian Stuart, CEO of UK HSBC, mentioned to MPs last month. “We are under constant attack,” he added.
Following the cyberattack, M&S was compelled to halt online orders for six weeks. Photo: Yui Mok/Pa
According to Stuart, HSBC alone needs to invest hundreds of millions to bolster their security. “This represents our largest expenditure.”
Globally, banks are projected to dedicate 11% of their IT budgets to cybersecurity by 2025, as indicated by an EY survey. This budget is expected to reach $290 billion (about £21.4 billion). By December, banks may invest $32 billion in cybersecurity, according to Celent’s research.
Cybercriminals represent a new kind of threat in the banking sector, evolving from masked robbers targeting physical branches to state-sponsored hackers and independent cybercriminals aiming for ransom or widespread chaos.
“Banks likely comprehend risk more profoundly than many other industries, investing significantly more in security,” states Stuart McKenzie, managing director at Mandiant Consulting, a Google-owned cybersecurity firm that collaborates closely with various UK lenders.
Last month, the Governor of the Bank of England shared with the BBC that cybersecurity risks remain ever-evolving. “We are contending with adversaries who continually enhance their methods of attack, which I must remind the agency to prioritize,” said Andrew Bailey.
However, safeguarding systems is complex. Many high street banks operate on multi-layered IT architectures with numerous updates and add-ons. Incorporating third-party software and cloud services complicates matters further, leading to a convoluted system.
“We refer to it as the offensive side,” remarked Alan Woodward, a cybersecurity expert and professor at the University of Surrey. “The attack surface is expanding, resulting in more chances for attackers to exploit vulnerabilities.”
Historically, successful bank hacks have not been destructive enough to halt the economy completely. Instead, hackers typically target customer data and account information.
In 2021, a hacker from Morgan Stanley accessed personal information belonging to a corporate client by breaching a server operated by third-party consultancy firms.
Earlier, at the onset of the COVID-19 pandemic, an attacker compromised a staff email for the Italian bank Monte Dei Paschi, sending a client a voicemail with malicious attachments.
In 2016, hackers guessed bank card details from over 9,000 Tesco Bank accounts, managing to steal nearly £2.5 million. Photo: Murdo Macleod/The Guardian
Notably, one of the worst hacking incidents in UK banking occurred in 2016, where criminals speculated on card details, leading to the theft of approximately £2.5 million from Tesco Bank accounts. In the aftermath, Tesco had to stop all online and contactless transactions to mitigate fraudulent activity occurring globally, including in Spain and Brazil.
In the end, Tesco Bank fully refunded its customers.
The National Cyber Security Center advises customers who suspect a breach to reach out to their banks through official websites or social media channels, avoiding any links or contact details shared in suspicious communications. Organizations should be able to confirm the status of the breach and provide guidance on next steps.
Since 2013, the Bank of England has actively recognized cybersecurity as a financial stability risk and initiated supervision of cyber resilience standards for all regulated banks and insurance firms.
The initiative includes the launch of CBEST, the first global program where ethical hackers evaluate the potential vulnerabilities of banks using advanced attack techniques.
“Nothing is absolutely secure,” emphasized Woodward, but he noted that the UK banking system is nearing that goal. “Much of this stems from oversight,” particularly by the central bank, which gathers intelligence from MI5, GCHQ, and NCSC, and conducts real-world scenarios to assess bank resilience.
Every two years, the central bank orchestrates the Multiday Cyberwar game as part of the Simex-Simulation Exercise program, assessing the security of businesses in London.
Additionally, authorities have been scrutinized, with banks, financial regulatory bodies, the Treasury, and the National Cybersecurity Centre evaluating their preparedness for various catastrophic incidents.
Regulators don’t just review bank defenses; they also encourage banks to develop response and recovery plans to mitigate long-lasting disruptions caused by potential cyberattacks, as it’s crucial for their success.
The Cross Market Business Continuity Group, connecting regulators with representatives from UK Finance in the banking sector, boasts the capability to convene approximately 100 firms for emergency discussions within an hour during potential threats.
Avoiding breaches is deemed essential for safeguarding industries that ultimately rely on trust. Customers expect banks to protect their data, incomes, and life savings from outside threats.
“If anyone can breach that security and execute a fraudulent transaction… you will lose trust in that bank, right?” remarked Woodward.
Banks have already faced backlash from mere IT disruptions, even without malicious intent aiming to undermine the banking system or steal sensitive information.
TSB has spent years rehabilitating its image after the IT collapse in 2018, caused by a failed separation from Lloyds’ internal systems, which led to millions of customers being locked out of their accounts for weeks. The bank was subsequently fined £48 million for “serious and widespread” failures.

Data gathered by the Parliamentary Treasury Committee indicates that the repercussions continue to affect some of the UK’s largest banks and their client bases, with significant IT failures over an extended period between January 2023 and February 2025.
“Customer money and data security are paramount for banks, not only due to regulatory demands but also as a cornerstone of their business model.”
“While I don’t dismiss the potential for cyber incidents, I remain confident in the level of cyber defense we maintain.”
Charming animal images are a fast way to uplift anyone’s spirits, and sharing these moments fosters a sense of community.
When someone shares a photo of a playful kitten with their parents or a video of an otter clasping paws, they participate in a phenomenon known as “pebling.”
“Pebling refers to a behavior exhibited by Gentoo Penguins, who offer pebbles as symbols of affection to potential partners,” explained Professor Ghalia Shamayleh, who led the study as noted in BBC Science Focus. “Our findings indicate similar behaviors among humans on social media.”

According to Shamayleh, the images, videos, and posts we share online serve as “the pebble equivalent for humans.” We send them to our loved ones as tokens of affection to reinforce our connections.
Animal-themed posts particularly enhance these “pebbles.”
The research, centered around social media accounts dedicated to pets, revealed that creators “infuse joy, love, and entertainment into their social media content.”
This often manifests through visual storytelling, such as taking pets on adventures or introducing them to family members. It also employs “Petspeak,” a blend of baby talk like “dogo,” “teefe,” and “sploot,” alongside playful language and slang.
Animals hold a universal charm. Who doesn’t enjoy seeing pictures of cute puppies or kittens?
In everyday settings, animals act as “social lubricants,” bringing people together to express “AWW” and lift their spirits. This effect becomes even more pronounced in the online world.
Initially, sharing an animal photo may suggest a level of unfamiliarity that prevents sending something more personal.
However, the research indicated that people thoughtfully consider the social media content they choose to share.
Shamayleh and her co-authors, including Professor Zeynep Arsel from Concordia University, analyzed several pet-focused media accounts to understand user interactions and conducted interviews with various content creators and fans.
They found that individuals utilize images and videos to evoke shared experiences among loved ones, reminiscing and reaffirming common histories.
For instance, one might send a friend a brief clip of two baby pandas attempting to stand, accompanied by the comment, “Just like in your first yoga class and mine.”
The study found that incorporating “context clues,” such as the music in this video, influenced how people reacted and what content was shared.
By selecting posts that resonate with the recipient’s interests, senders are able to convey a deeper understanding of their loved ones, by sharing videos of their favorite animals.
“By referencing the sender’s relationship alongside animal content, individuals digitally emphasize their bond, saying, ‘This reminded me of you and our connection,'” remarked Shamayleh.
So, the next time you come across a delightful animal photo or video, don’t hesitate to share it and show your loved ones how much you care.

Recent studies indicate that the fats found in olive oil may contribute to weight gain more significantly than fats from other sources.
A recent report revealed that oleic acid, the primary fatty component in olive oil, can stimulate the formation of new fat cells.
Oleic acid is a type of monosaturated fat, often referred to as omega-9. While olive oil is the main source of oleic acid, this fatty acid is also present in other oils, such as canola and sunflower oil.
“You can think of fat cells as the army,” stated the study’s co-author, Dr. Michael Rudolph, Assistant Professor of Biochemistry and Physiology at the University of Oklahoma. “Dried oleic acid initially boosts the number of ‘fat cell soldiers’ in the army, enhancing the capacity to store surplus dietary nutrients.”
“If excess nutrients surpass the number of fat cells over time, it can lead to obesity, and if left unaddressed, may result in cardiovascular disease or diabetes.”

Researchers from the University of Oklahoma, Yale University, and New York conducted a study where mice were fed a variety of high-fat diets that included coconut oil, peanut oil, milk, lard, and soy oils.
They found that elevated levels of oleic acid influenced the activity of two proteins, AKT2 and LXR, leading to an accelerated growth of progenitor cells that develop into new adipocytes. This effect was not observed with other types of fats.
Nevertheless, Dr. Rudolph emphasized that completely eliminating olive oil is not the answer.
“The key takeaway is moderation and diversifying fat sources,” he advised. “While a balanced intake of oleic acid can be beneficial, excessive and prolonged consumption may pose risks. For individuals at risk for heart disease, high oleic acid levels could be unfavorable.”
In moderation, oleic acid is linked with numerous health benefits. Previous studies have shown that olive oil consumption is associated with longer lifespans, healthy aging, reduced inflammation, and a decreased risk of obesity and heart disease.
It’s important to note that since this study was conducted exclusively on mice, its findings may not directly apply to humans.
Though it might not be as well-known as the Hubble Space Telescope or the James Webb Space Telescope, NASA’s Landsat 7 has significantly enhanced our understanding of our planet. For over 25 years, it has been capturing the stunning landscapes of Earth from space, documenting remarkable details of the planet’s ever-changing environment.
Launched in 1999 with an expected mission duration of only five years, Landsat 7 has instead emerged as one of the longest-running Earth observation missions in history. While it doesn’t gaze into distant galaxies, its instruments are focused on the vibrant, living surfaces of Earth instead.
From an altitude of 700 km (about 435 miles), it has produced vital data for scientific research and conservation, showcasing stunning images of dynamic deserts, glaciers, forests, and coastlines.
“[Landsat 7 has] been essential in tracking environmental changes such as natural disasters, deforestation, and urban expansion,” said David Applegate, former director of the US Geological Survey.
“It documented significant events such as Hurricane Katrina in 2005, the Haiti earthquake in 2010, the Australian wildfires from 2019 to 2020, and rapid urban growth across the globe.”

Landsat 7 is scheduled to retire this month after covering 6.1 billion km (3.8 billion miles) in space and capturing over 3 million images. A carefully planned shutdown will involve depleting its batteries, turning off the fuel line heater, and rendering the communications system silent permanently. For another 55 years, the satellite will drift silently above Earth before eventually re-entering the atmosphere and burning up.
As we bid farewell, we reflect on its lens and celebrate the beauty and complexity of our planet, revealing both the impacts of deforestation and the intricate patterns of continents.

IT concluded a few years back, yet Westworld seems to be fading into a TV footnote. I scarcely recall a mid-2010s reimagining of the Yul Brynner film from the 70s. HBO’s robotic cowboy saga endured four underwhelming seasons before its cancellation.
Nonetheless, when it debuted, Westworld generated a lot of buzz. It was HBO’s sci-fi equivalent to Game of Thrones. The series boasted high production values along with a visually striking cast, including Evan Rachel Wood, Ed Harris, Tandiwe Newton, and Jeffrey Wright, led by the talented duo of Lisa Joy and Jonathan Nolan. At that moment, this project held significant promise in a period flooded with repetitive content. There was genuine apprehension about a show that “makes it up as they go along” (as a devoted fan, I must assert that “they haven’t made it up as they go along,” but that’s a discussion for another newsletter).
However, even the most elaborately planned television shows can unravel. The first hint that Westworld might not ascend to greatness came when forum/social media platform Reddit users began accurately predicting plotlines. Redditors anticipated the twists and turns of the first season, often well in advance and even familiar with the show’s rhythm and patterns. Things escalated to such an extent that in the second season, Joy and Nolan had to rewrite the script to divert the course already hinted at by Reddit users. This not only indicated Westworld’s fragility but also highlighted the formidable influence of Reddit and its community, capable of shaking seasoned showrunners.
Of course, Reddit has since eclipsed Westworld. This month marks the site’s 20th anniversary, though often mischaracterized as an “internet front page.” Celebrated this February, the anniversary brings to mind the more seismic debut of YouTube in 2005. The impact of YouTube on popular culture has been quite significant, even surpassing traditional television.
Reddit’s emergence coincided with an era marked by intense fandom and parasocial relationships. Dedicated fan forums existed prior to Reddit, from band and solo artist message boards to TV show discussions. However, Reddit streamlined and amplified these communities, fostering an environment where niche musical microgenres and discussions could flourish openly under one large digital umbrella.

This newfound freedom and openness, however, comes at a cost. Reddit has faced heavy scrutiny for misogyny, racism, conspiracy theories, and threats of violence. In contrast to many other social media platforms today, Reddit has made substantial strides in community moderation over the past decade. Pop culture discussions can sometimes spiral into more troubling territory, as seen in the long and complicated history surrounding the Rick and Morty subreddit.
Yet, discussions surrounding Reddit often focus too heavily on its negative aspects, neglecting what a surprisingly positive space it can be. With dedicated moderation efforts, it’s one of the last bastions of the old internet—quirky, supportive, and a bit eccentric. As The Atlantic aptly puts it, Reddit is “both niche and vast.” This duality allows it to be explored superficially and in depth, like communities such as Build a Gurdy. In many ways, it represents a mainstream obsession where hyper-specific communities are no longer hidden away but are easily accessible under one broad Reddit umbrella.
I wouldn’t classify myself as a prominent member of this community. At best, I am a Reddit lurker—not bold enough to engage actively and post—but as someone chronicling pop culture, I find it endlessly beneficial. Whether I’m delving into the puzzling narrative threads of a show through its insightful subreddit or seeking out an obscure 70s paranoid thriller, I turn to R/Movie Suggestions. And I can’t even count the number of bands I’ve discovered on major boards like r/indieheads (boasting 3.6 million members and growing). The last time I visited r/indieheads, a user had commemorated Brian Wilson’s death, sharing everything I wanted to hear in a lively, informed exchange.
That essence prompts me to wonder whether some level of concern could tarnish the site, despite the stock market’s buoyancy. Perhaps one day this fear will dissipate, or perhaps not. Maybe Reddit is simply too significant, too unique, and too defiantly independent to be tamed by large corporations. I hope we can celebrate it again in another twenty years as it continues to cover yet another pedestrian TV series.

British workers need to embrace AI and turn their apprehensions into “exhilarating” experiences, or risk being outpaced by their peers, stated the technical secretary.
Peter Kyle urged both employees and businesses to “act quickly” to engage with new technologies.
Innovations like the advent of ChatGPT have triggered significant investments in technology, although it is expected that numerous roles across various sectors, including law and finance, will be impacted.
Kyle remarked: “[Using AI] leads to a sense of exhilaration, as it is often simpler than people think and more rewarding than they anticipate.”
After speaking with the leader of a technology firm, Kyle addressed the government’s initiative to train 7.5 million British workers in AI by 2030, with support from companies like Google, Amazon, and BT.
He added:
“It’s an optimistic message: act now, and you’ll prosper in the future. Failing to act could leave some behind, which is my biggest concern.”
Kyle pointed out a generational divide in AI usage, noting that individuals over 55 are adopting AI technologies more than those over 35. He suggested that merely two and a half hours of training might bridge this gap.
“There’s no need for people to delve into quantum physics,” Kyle emphasized. “They simply need foundational training on how AI functions and how to engage with it, discovering the opportunities available to them in the workplace.”
This week, Keir Starmer acknowledged that many are “skeptical” about AI and anxious about their job security. At London Tech Week, the Prime Minister stated that the government aims to demonstrate how technology can “generate wealth in your community” and significantly enhance public services.
According to recent polling data shared with the Guardian, individuals in English-speaking nations, such as the UK, the US, Australia, and Canada, express greater anxiety about AI’s rise compared to those in the largest EU economies.
Predictions regarding AI’s impact on employment vary, with organizations like the OECD warning that automation may lead to job losses in skilled sectors like law, healthcare, and finance. The International Monetary Fund reports that 60% of jobs in advanced economies like the US and UK are at risk from AI, with half potentially facing negative repercussions.
Nonetheless, the Tony Blair Institute advocates for the broad adoption of AI across both public and private sectors, arguing that potential job losses in the UK private sector will be offset by new roles created through technology.
Kyle expressed his intention to reset the conversation around AI and copyright after opposing the government’s proposed revisions to copyright law. The Data Bill, which included controversial provisions allowing AI firms to use copyrighted material without consent, was approved after no further amendments related to copyright were submitted by the Lords.
“I approach this with humility and a willingness to reflect on how I could have handled things better,” he stated. “I am committed to moving forward with a renewed focus on what creative rights can offer in the digital age, akin to the benefits enjoyed by generations in the analog era.”
As opponents of US water fluoridation voice their concerns, scientists warn that eliminating fluoride may lead to a significant rise in dental decay, potentially costing states billions and disproportionately impacting lower-income communities.
Statements from states like Nebraska, Kentucky, and Louisiana indicate their intentions to remove fluoride from water supplies, raising questions about how quickly these changes will affect Americans.
Fluoride Variation
Fluoride is a naturally occurring mineral found in freshwater, initially added to community drinking water in the United States in a controlled manner in 1945. Effective methods to prevent dental decay.
According to the CDC, community water fluoridation was reported in 1999, promoting the development of baby teeth and safeguarding them through adulthood. This initiative is recognized as one of the 20th century’s greatest public health achievements.
Recently, however, concerns have emerged that adding fluoride through foods, milk, toothpaste, and dental care products could lead to total fluoride intake surpassing safe levels.
Nevertheless, the NTP noted that there was insufficient data to establish whether the lower US fluoride level of 0.7 mg/L negatively impacts children’s IQ, admitting that out of 74 international studies evaluated, “52 were deemed low quality (high risk of bias).”
Vida Zohoori, a public health and nutrition professor at Teesside University in the UK, is known for her research on fluoride. She asserts that the studies available do not provide enough data to reach definitive conclusions.
“Most research occurs in regions with fluoride concentrations significantly exceeding US standards, limiting the relevance to community water fluoridation at 0.7 mg/L,” she explains. “Most studies are cross-sectional, not longitudinal or randomized, making it impossible to establish causal links. Furthermore, many did not control for key variables like iodine or lead exposure, malnutrition, and socioeconomic status.
Children’s teeth are particularly prone to decay
Conversely, there is substantial evidence supporting the addition of safe fluoride levels to drinking water. Based on a systematic Cochrane Review from 2015 (updated in 2024), Zohoori anticipates a notable rise in pediatric decay, known as early childhood tooth decay (ECC), if fluoride is removed from public water supplies. This primarily affects children aged 1-5 and the permanent teeth of those aged 6-12, who are extremely susceptible to damage.
This perspective is echoed by Dr. James Becker, an associate professor specializing in pediatric dentistry at the University of Utah. “No scientifically credible research has demonstrated harmful effects from fluoride when administered at safe doses,” he remarks.
Bekker explains that while toothpaste fluoride provides a topical effect during brushing, small amounts in drinking water and supplements deliver continuous systemic exposure, which reinforces tooth enamel and enhances its resistance to acid.
“Many children lack access to fluoride supplements,” Bekker noted, emphasizing that fluoridation was only present in half of Utah prior to the ban.
“We’ve observed a significant increase in tooth decay in communities without fluoridated water compared to those with it. If left untreated, cavities can enlarge and eventually reach the tooth’s nerves, leading to infections and the loss of teeth.”
If all 50 US states discontinue community water fluoridation programs, it is projected that children and adolescents aged 0 to 19 will incur 25.4 million cavities in the next five years, equating to one new cavity for every three children in America. A recent report indicated this would result in an estimated cost of $9.8 billion (£7.2 billion). Jama Health Forum in May.
“We specifically quantified the increase in dental cavities that could necessitate interventions ranging from fillings to root canals and even extractions,” stated Dr. Lisa Simon, a PhD fellow in Oral Health and Medicine Integration at Harvard Dental School and co-author of the study.
“We accounted for decay in both baby teeth and adult teeth, which began to escalate when the children were around six years old.”
Lessons Learned
With the fluoride ban in Utah now in effect, Bekker anticipates it could take five years to observe its full impact. However, the effects were evident even sooner in Calgary, Canada, which removed fluoride from its drinking water in 2011; three years later, children’s dental decay surged.
In one year, 32 out of Calgary’s 10,000 children underwent general anesthesia for dental treatments, whereas only 17 did so in Edmonton, another city within the same province. Subsequently, Calgary voted to reinstate fluoride.
The leading reason for children aged 5 to 9 being admitted to hospitals is treatment for tooth decay.
“Recent studies indicate the benefits of water fluoridation are less pronounced than in the past, particularly since fluoride has become a common ingredient in toothpaste since the 1970s.”
“However, rates of tooth decay are rising, and increased education on dental care is essential. The frequency of sugar intake is key to prevention, which supports water fluoridation initiatives in the UK.”
Dr. Scott Tomar, a professor and associate dean of Prevention and Public Health Sciences at the University of Illinois, Chicago, and spokesperson for the American Dental Association, commends the UK’s fluoridation expansion.
He expresses concern that misinformation about fluoride in the US could induce fear surrounding other sources of minerals, including toothpaste, leading to more bans across various states and communities.
Tomar highlights the overwhelming support for fluoride within the dental community as indicative of its safety and effectiveness, countering any narratives that oppose it driven by the economic interests of dentists.
“So, why do we advocate for this type of water fluoridation?” he inquires. “I’m genuinely worried because there are no alternatives to fluoride, and we can no longer rely on the federal government for guidance.”
In light of this, dentists and industry groups are joining forces to advocate for their cause.
“This appears to be primarily a political issue,” comments Lorna Kosi, chair of the coalition in Davis and program director for a dental clinic serving vulnerable communities. “We firmly believe that water fluoridation is safe. It remains the most effective and cost-efficient method to combat decay.”
An unusual radio pulse was identified by the Antarctic Impulsive Transient Antenna (ANITA) Experiment. Various instruments were deployed on NASA balloons over Antarctica, aiming to detect radio waves produced by cosmic rays impacting the atmosphere. This experiment seeks to illuminate events in the distant universe by scrutinizing signals that reach Earth. Rather than bouncing off the ice, this radio signal seemed to originate from beneath the horizon. Such a direction challenges our current understanding of particle physics and might indicate a previously unknown particle or interaction.
ANITA instruments were stationed in Antarctica to minimize interference with other signals. The setup involves balloon-mediated radio detectors flying through ice to capture what is known as an ice shower. Image credit: Stephanie Wissel/Penn State.
“The detected radio waves were highly angled, approximately 30 degrees below the ice surface,” said physicist Dr. Stephanie Wissel from Pennsylvania State University.
“Our calculations suggest the anomalous signal interacted with thousands of kilometers of rock before reaching the detector.
“This poses an intriguing question as we have yet to understand these anomalies fully. However, we do know they likely do not represent neutrinos.”
Neutrino signals typically emerge from high-energy sources such as the sun or significant cosmic events like supernovae and the Big Bang.
Yet, these particles present a challenge: they are notoriously difficult to detect.
“A billion neutrinos pass through any point instantly, but they rarely interact,” Dr. Wissel explained.
“This presents a paradox. If we detect them, it means they traversed this way without interacting with anything else.”
“We can even identify neutrinos originating from the edge of the observable universe.”
“When observed and traced back to their source, these particles travel at speeds comparable to light, offering insights into illuminative events that reveal more than the most powerful telescopes.”
“Researchers globally have been focused on creating specialized detectors to capture faint neutrino signals.”
“Even a minor signal from neutrinos can unveil valuable information, making all data crucial.”
“We’re aiming to utilize radio detectors to establish a significant neutrino telescope, anticipating low event rates.”
ANITA was one of these detectors, positioned in Antarctica to reduce interference from other signals.
To capture the ejection signal, it deploys a balloon-mediated radio detector to traverse ice stretches and identify what is known as an ice shower.
“We operate these radio antennas on balloons that soar 40 km above the Antarctic ice,” Dr. Wissel noted.
“We lower the antennas into the ice, searching for neutrinos that interact within the ice, resulting in radio emissions detectable by the instrument.”
These unique ice-interacting neutrinos, termed tau neutrinos, generate secondary particles called tau leptons that are released from the ice as they lose energy traveling through space, producing emissions identified as air showers.
“If visible to the naked eye, an air shower may resemble a sparkler dispersed in one direction.
“We can distinguish between two signal types (ice and air shower) and ascertain details about the particles that produced the signals.”
“These signals can be traced back to their sources, akin to how balls thrown at angles bounce back predictably.”
However, the recent peculiar findings cannot be traced because they display sharper characteristics than existing models anticipate.
By analyzing data gathered from multiple ANITA flights and contrasting it with thorough simulations of both mathematical models and common cosmic rays and upward air showers, researchers successfully eliminated background noise and ruled out possibilities of known particle-based signals.
Scientists then cross-referenced signals from other independent detectors, including the IceCube experiment and the Pierre Auger Observatory, to determine if any upward-facing air shower data had been captured by other experiments similar to those identified by ANITA.
The analysis disclosed that no other detectors documented anything capable of explaining what ANITA detected, leading researchers to characterize the signal as abnormal. This indicates that the particles responsible for the signal are not neutrinos.
The signal defies conventional paradigms in particle physics. Some theories propose it could hint at dark matter; however, the absence of follow-up observations from IceCube and Auger significantly diminishes this possibility.
“Our team is in the process of designing and constructing the next major detector,” Dr. Wissel shared.
“We aspire for a new detector called Pueo to be larger and more adept at identifying neutrino signals, which should clarify the nature of the abnormal signal.”
“My hypothesis is that some intriguing radio propagation phenomena occur near the ice, close to the horizon—effects I don’t fully comprehend, but we are certainly investigating them.
“So, this is one of those enduring mysteries, and we are eager to achieve enhanced sensitivity when we deploy Pueo.”
“In principle, we should detect more anomalies, and perhaps we’ll decipher their nature.”
“We could also encounter neutrinos, which would be tremendously exciting in their own right.”
The team’s paper was published in the journal Physical Review Letters.

This article is based on a press release provided by the Pennsylvania State University.
Gigantic herbivores in the Americas vanished roughly 10,000 years ago, disrupting the long-range seed dispersal of sizable fleshy plant species. The Anachronistic hypothesis of the Neotropics, proposed in 1982, posits that large fruits evolved to attract these massive animals. While this idea accounts for several significant adaptations in “megafaunal fruit” plants, it lacks strong evidence. Recently, researchers from Chile, Spain, and Brazil uncovered fossil evidence of frugivory, pointing to the existence of the extinct South American species Notiomastodon platensis. Their findings indicate that the extinction of this species and its relatives heightens the risk of giant fruit plants becoming extinct in certain South American regions.

“In 1982, biologist Daniel Jansen and paleontologist Paul Martin proposed groundbreaking ideas, suggesting that many tropical plants developed large, sweet, colorful fruits to attract large animals like mastodons, native horses, or giant herds,” said iphes-cerca and colleagues.
“The theory, known as the anachronism hypothesis of the Neotropics, has remained unverified for over four decades.”
“Our research provides direct fossil evidence to substantiate this concept.”
In this study, Dr. González-Gurda and co-authors examined 96 fossil teeth from the Pleistocene mastodon, Notiomastodon platensis.
These fossils were collected over a distance of more than 1,500 km, spanning from Los Bilo to Chiloe Island in southern Chile.
Nearly half of the specimens originated from well-known sites such as Lake Tagua, an ancient basin abundant with Pleistocene fauna located in the current O’Higgins region.
To understand the lifestyle of Notiomastodon platensis, various techniques were utilized including isotopic analysis, microscopic examination of dental wear, and fossil calculation analysis,” the authors stated.
“We discovered typical starch residues and plant tissues of fleshy fruits, including the Chilean palm (Jubaea chilensis),” added Professor Florent Rivals, a researcher at ICREA, Iphes-Cerca, and Rovira I Virgili University.
“This directly confirms that these animals regularly consumed fruit and contributed to reforestation.”
“Stable isotopic analysis enabled us to reconstruct the animal’s habitat and diet with high accuracy,” noted Dr. Ivan Ramirez Pedraza, a researcher at Ifes Serca and Rovira I-Vilgiri University.
“The data points to a forest ecosystem rich in fruit resources, where mastodons roamed across long distances, aiding in seed dispersal. Its ecological role remains pivotal.”
“Dental chemistry offers us a direct glimpse into the past,” commented Dr. Carlos Tornero, a researcher at Ifes Cerca and the Autonomous University of Barcelona.
“Combining various evidence allowed us to strongly affirm the critical role they played within these ecosystems.”
The researchers also employed machine learning models to assess the current conservation status of megafauna-dependent plants across different regions of South America.
Their findings are intriguing: in central Chile, 40% of these species currently face threats. This ratio is four times higher than that of tropical regions where animals like tapirs and monkeys continue to function as alternative seed dispersers.
“If the ecological connection between plants and animals is completely severed, the repercussions will be evident for thousands of years,” states ecosystem researcher Andrea Leuza.
The survey results were published today in the journal Nature’s Ecology and Evolution.

Recent observations suggest the existence of a volcanic formation at the edge of Mars’ Jezero Crater, currently under investigation by NASA’s rover. This rover might already be collecting samples from materials expelled during an ancient volcanic eruption.
Perseverance, which landed in Jezero Crater in 2021, is methodically moving toward the western edge, tracing an ancient river that is believed to have flowed between 300 million and 4 billion years ago.
The rover is gathering samples meant to be returned to Earth as part of the Mars Sample Return mission planned for the 2030s. However, this endeavor faces potential cuts proposed by the Trump administration affecting NASA’s funding.
Some of the materials in the samples were thought to be volcanic, showcasing characteristics of lava flow. Recently, James Ray from Georgia Tech in Atlanta and his team have identified a possible volcanic structure at Jezero Mons—a dormant volcano situated on the southeastern edge of Jezero.
High-resolution images from Martian orbiters have revealed fine-grained materials in the vicinity, possibly indicating ash from the volcano. The dimensions and shape of Jezero Mons—21 km wide and 2 km high—parallel those of similar volcanoes on Earth.
“The evidence for igneous volcanoes is most consistent with our observations,” states Ray, noting that magma may have originated from beneath the surface. “This is the strongest case we can make without physically visiting the site.”
By analyzing the craters near the volcano, Ray and his colleagues estimate that Jezero Mons may have last erupted around a billion years ago.
This finding suggests that the rover might have collected volcanic samples. If they can be returned to Earth, scientists would be able to accurately date volcanic activity on another planet for the first time.
“Knowing when that volcano was active is incredibly exciting,” exclaimed Briony Hogan from Purdue University in Indiana, a member of the rover’s science team. This information could significantly enhance our understanding of “how the interiors of planets evolve over time,” she adds.
Ideally, Ray mentions that he hopes to direct Perseverance to the volcano itself, but acknowledges this may not be feasible. “There are really fascinating ancient rocks to the west of the crater, so they’re likely driving in the opposite direction,” he explains. “I can’t blame them.”
Researchers have discovered the first known “ghost plume” beneath Oman, suggesting a column of hot rock rising from the lower mantle with no visible volcanic activity on the surface.
The mantle plume is a mysterious intrusion of molten rock believed to transfer heat from the core-mantle boundary to the Earth’s surface, sometimes occurring beneath the heart of continental plates, as seen in regions like Yellowstone and East Africa. Notably, “these scenarios typically feature surface volcanoes,” states Simone Pilia from King Fahd University of Petroleum and Minerals in Saudi Arabia. Oman lacks such volcanic indicators.
Pilia first hypothesized the existence of this “accidental” plume while examining new seismic data from Oman. The analysis revealed that seismic waves from distant earthquakes travel more slowly through a cylindrical region beneath eastern Oman, indicating it is less dense than surrounding materials due to elevated temperatures.
Additional independent seismic assessments identified critical boundaries where Earth’s deep minerals undergo changes that align with the hot plume’s characteristics. This evidence suggests the plume extends over 660 km from the surface.
The presence of these plumes also explains why the region continues to elevate despite geological compression, a process where the crust is squeezed together. This discovery fits models that explain alterations in Indian tectonic plate movements.
“The more evidence we collected, the more convinced we became it was a plume,” remarks Pilia, who has named this geological feature the “Dinni plume” after her son.
“It’s plausible that this plume exists,” agrees Saskia Goes at Imperial College London, adding that this study is “thorough.” Nevertheless, she emphasizes that identifying narrow plumes is notoriously challenging.
If verified, the existence of a “ghost plume” trapped within Oman’s relatively thick rocky layers suggests there might be others. “We are confident that the Dinni plume is not alone,” says Pilia.
If multiple hidden plumes exist, it could indicate that heat from the core is transferring more readily through the mantle in these regions, influencing our understanding of Earth’s evolutionary history.
Manipulating Giant Atoms for Enhanced Quantum Computing
koto_feja/istockphoto/getty images
Recently, giant atoms have emerged as prime candidates for the development of advanced quantum simulators and computers, thanks to researchers demonstrating control over them for an extended period in room temperature environments.
Using electromagnetic pulses or laser light, scientists can modify the quantum properties of an atom—allowing for the adjustment of electron energy to encode information. Manipulating thousands of such atoms paves the way for constructing a quantum computer or simulating unusual quantum materials. However, spontaneous state changes in atoms can cause errors, with these atoms being controllable only within a limited “lifetime,” previously recorded at up to 1400 seconds. Despite advancements in trapping atoms longer, these methods typically required refrigeration systems, leading to logistical hurdles.
Zhenpu Zhang and Cindy Regal, along with their colleagues at the University of Colorado Boulder, have shattered previous room temperature records by employing Rydberg atoms. These atoms have outer electrons positioned far from the nucleus, resulting in a larger atomic diameter. The research team successfully loaded these atoms into a vacuum chamber, effectively blocking interfering air particles and employing laser-based “optical tweezers” for precise atom manipulation. This technique is standard for controlling Rydberg atoms, noted for their sensitivity to electromagnetic fields and light.
The team enhanced their setup by adding a copper layer inside the container, which they cooled to -269°C (-452°F). This cooling shields the atoms from thermal interference that could alter their states. Additionally, Zhang explains that air particles condense onto the copper walls, akin to how water droplets form on cold surfaces, further improving the vacuum within the chamber. Consequently, they managed to maintain control of approximately 3000 seconds (or 50 minutes), which is nearly double that achieved in previous experiments.
Zhang has been developing this innovative setup for five years from the ground up. Regal adds, “This represents a significant evolution in how we approach these experiments.”
Clement Sayrin of the Kastler Brossel Laboratory in France emphasized that this new methodology may facilitate manipulating even more atoms. “3000 seconds is quite impressive. Achieving such extended lifetimes for these atoms demands considerable effort,” he states. However, as the number of atoms in the chamber increases, so does the requirement for additional lasers to control them, potentially shortening the atomic lifespans and introducing further engineering challenges, according to Sayrin.
Prevalent strains of avian flu affecting US livestock
Mediamedium/Alamy
Since the beginning of Donald Trump’s administration in January, key US public health organizations have reduced their pandemic preparedness efforts regarding potential avian flu outbreaks. However, in contrast, another government agency has ramped up its activities.
The U.S. Department of Health and Human Services (HHS) previously conducted regular updates on measures to prevent a broader transmission of the deadly avian influenza virus known as H5N1 among humans, but these efforts were largely suspended after Trump took office. Funding for vaccines targeting the virus was also cancelled. Meanwhile, the USDA intensified its fight against the spread of H5N1 in poultry and dairy populations.
This particular strain of avian flu, named H5N1, poses a significant risk to human health, with about half of the nearly 1,000 individuals who tested positive globally since 2003. While the virus spreads quickly among birds, it remains poorly adapted to infect humans and is not known to transmit between individuals. However, mutations might enhance its ability to spread among mammals, presenting an escalating risk with increasing infections in mammals.
The likelihood of H5N1 evolving into a more human-threatening variant has significantly amplified since March 2024, when it transitioned from migratory birds in Texas to dairy cattle. More than 1,070 flocks across 17 states have since been affected.
H5N1 also impacts poultry, making it more human-compatible. Since 2022, nearly 175 million domestic birds in the US have been culled due to H5N1, with 71 people testing positive after direct contact with infected livestock.
“We must take [H5N1] seriously. Its spread continues, and it frequently spills over into humans,” says Sheema Calkdawara from Emory University in Georgia. The virus has already claimed lives in the US, including children in Mexico this year.
However, the number of incidents has minimized since Trump took office, with the last recorded human case in February and a significant reduction in affected poultry herds by 95% from then through June. Outbreaks within dairy cattle herds are also being managed effectively.
The cause of this decline remains unclear. Some speculate it may be due to a decrease in bird migration, limiting the opportunities for the virus to jump from wild birds to livestock. It may also reflect the USDA’s proactive containment strategies on farms. In February, USDA detailed a $1 billion investment plan to combat H5N1, which includes free biosecurity evaluations to help farmers enhance their defenses against the virus. Only one workplace among the 150 reviewed reported an outbreak.
Under Trump’s administration, the USDA also maintained its national milk testing initiative, requiring farms to submit raw milk samples for influenza testing. Should a farm test positive for H5N1, the USDA can monitor livestock and take preventative measures. The USDA initiated a comprehensive program in December, further enhancing their engagement in 45 states.
“The National Milk Test Strategy is a robust approach,” states Erin Sorrell from Johns Hopkins University in Maryland. Coupled with improvements in on-farm biosecurity, milk testing is crucial for containing outbreaks, Sorrell believes.
Despite the USDA’s heightened efforts concerning H5N1, HHS doesn’t seem to be keeping pace. According to Sorrell, the decrease in human cases may also be due to diminished surveillance resulting from staff cuts. In April, HHS announced 10,000 job cuts, impacting 90% of the workforce at the National Institute for Occupational Safety and Health, which monitors H5N1 incidence among farm workers.
“As the saying goes, you can’t detect something unless you test for it,” Sorrell comments. Nevertheless, a spokesperson from the US Centers for Disease Control and Prevention (CDC) stated that their guidance and surveillance initiatives remain unchanged. “State and local health departments are still tracking illnesses in individuals exposed to sick animals,” they expressed to New Scientist. “The CDC is dedicated to promptly sharing information regarding H5N1 as necessary.”
Vaccination strategies are another area of contention between USDA and HHS. USDA has allocated $100 million towards the development of vaccines and additional strategies to mitigate H5N1’s spread among livestock, while HHS has halted $776 million in contracts aimed at developing influenza vaccines. This contract, which ended on May 28, was with Moderna for a vaccine targeting various influenza subtypes, including H5N1, potentially leading to future pandemics. This announcement coincided with Moderna revealing that nearly 98% of around 300 participants who received two H5 vaccines in clinical trials exhibited antibody levels considered protective against the virus.
The US currently possesses approximately 5 million doses of the H5N1 vaccine, produced via egg-based and cultured cell methods, which is more time-consuming compared to mRNA vaccines such as Moderna’s. Sorrell observes that Moderna’s mRNA vaccine platform enables rapid government response and production capabilities during a pandemic, providing a solid foundation should a general public vaccine be required.
HHS’s cancellation of its contract stemmed from concerns regarding the mRNA vaccine technology, an issue previously flagged by Robert F. Kennedy Jr., a leading public health figure in the nation. “The reality is that mRNA technology remains inadequately tested, and we will not waste taxpayer dollars repeating past errors,” stated HHS Communications Director Andrew Nixon, as reported by New Scientist.
However, mRNA technology is far from novel and has been in development for over 50 years, with various clinical trials confirming its safety. Like all treatments, there can be mild side effects, but these are typical of most medical interventions. In a recent announcement, Moderna indicated its intention to seek alternative funding avenues for the project.
“I firmly believe we shouldn’t dismiss any option, including various vaccine strategies,” asserts Calkdawara.
“Vaccinations are the most effective defense against infectious diseases,” emphasizes Sorrell. “Having them available as a contingency provides a wider range of options.”
This concept may surprise you, but certain tumors can indeed develop parts of your body, or at least fragments of them.
These peculiar layers, known as teratomas, originate from germ cells that possess the extraordinary capability to transform into any type of tissue.
Germ cells typically evolve into sperm or eggs; however, when their development is disrupted, they can create a disorganized mass of tissue.
The term “Teratoma” is derived from the Greek word Teras, which means “monster,” aptly reflecting its nature.
These tumors feature an astonishing array of components, ranging from hair and teeth to muscle tissues and even organ-like structures such as the thyroid and eyes.
While fully functional organs are exceedingly rare, the intricate nature of these tumors is undeniable.
Teratomas are most frequently observed in the ovaries and testes, but they can also appear in the midline of the body, such as the mediastinum (the chest area that houses the heart) and the base of the spine.
The majority of teratomas are benign and can be easily excised, though a small percentage—particularly those in men—can become malignant and necessitate urgent treatment. Surgery is generally the primary method for addressing these tumors, and the prognosis is typically favorable.

In addition to their medical implications, teratomas have offered significant insights into the science of cellular development.
They can include tissues derived from all three layers of germ cells, making them an intriguing model for studying how cells differentiate and organize.
So, can a tumor grow organs? In a way, yes. However, these structures are often nonfunctional and poorly organized.
Teratoma serves as a striking and unsettling example of the bizarre and unpredictable aspects of human biology.
This article addresses the question posed by Anisa Manning and Steve Nage: “Can tumors grow their own organs?”

A new method using small, lab-grown vascular structures has effectively restored blood flow to injured tissue in mice, significantly reducing necrosis. This technique shows promise for mitigating damage caused by injuries or blood clots in the future.
Previously, researchers developed vascular organoids by immersing human stem cells in a mix of chemicals, a process that took weeks and often resulted in structures that did not accurately replicate natural blood vessels, according to Juan Melero-Martin from Harvard University.
In a new approach, Melero-Martin and his team genetically modified human stem cells derived from reprogrammed skin cells. By introducing a genetic sequence and the antibiotic doxycycline, they were able to create vascular organoids in just five days. “The resulting blood vessels exhibited protein and gene activity levels closely resembling those of natural human tissues,” notes Melero-Martin.
To evaluate the organoids’ ability to rehabilitate damaged tissue, the researchers surgically obstructed the blood supply to one leg of several mice, reducing blood flow to less than 10% of normal. After an hour, they introduced 1,000 organoids at the injury site.
Two weeks post-implantation, imaging revealed that the new blood vessels had integrated with the existing ones, restoring blood flow to approximately 50% of normal levels, as stated by Oscar Abiles at Stanford University. “In cases of heart attacks, restoring even this amount of blood flow can significantly minimize tissue damage.”
Post-treatment, about 75% of the mice exhibited minimal dead tissue, while in a control group without organoid treatment, nearly 90% experienced severe tissue death.
In additional trials, the team treated mice with type 1 diabetes with organoids, which had caused pancreatic damage and elevated blood glucose levels. They discovered that integrating organoids with pancreatic tissue transplantation greatly enhanced glycemic control compared to transplantation alone.
However, further studies involving larger animals such as pigs are essential before considering human trials, Abirez states. Melero-Martin anticipates that human research could begin within five years.
Besides facilitating tissue repair, these findings may lead to the development of lab-grown mini-organs that more accurately represent bodily functions or even mini-tumors for research and treatment testing.
“Until recently, organoids lacked blood vessels and could only grow to a limited size. Beyond a few millimeters, they began to perish,” explains Abirez. “This study offers a method to incorporate blood vessels into organoids, thus enhancing their fidelity to human physiology and aiding treatment development.”
These stunning and eerie visuals showcase creatures born in Europe’s largest jellyfish breeding facility.
Photographer Heidi and Hans Jurgen Koch utilized a macro lens and studio lighting to create these images, though I was particularly intrigued by the jellyfish’s location, which cannot be photographed as it sinks to the bottom of a typical aquarium. The animals require “jellyfish” Kraisel or gyroscopes to generate necessary water movements; without them, swimming and feeding is impossible.

As jellyfish populations grow, they are increasingly seen as both an environmental challenge and a source of sustainable solutions, Koch asserts. With ocean temperatures rising, and issues like pollution and overfishing becoming more pressing, jellyfish numbers are surging, posing serious risks to ecosystems and economies.

Nevertheless, jellyfish also offer significant potential, including uses as animal feed, fertilizers, and even superfoods for humans, thanks to their anti-inflammatory and immunologically beneficial compounds. Their mucus can also serve as biofilters to keep plastics out of the oceans.
Pacific Compass Jellyfish (Chrysaora fuscescens) is featured in the main image. These jellyfish will be sent to zoos, aquariums, and research facilities. Below, the gyroscope simulates ocean currents for the Moon Jellyfish (Aurelia aurita). The pipette in the photograph shows Mangrove Jellyfish (Cassiopea xamachana).

As they mature, jellyfish reside on the seafloor, orienting their tentacles toward sunlight, where they have a symbiotic relationship with single-celled algae that assist with photosynthesis. The image above depicts jellyfish specimens being evaluated prior to shipment.
Elon Musk and Donald Trump have officially exited the scene, in case you haven’t noticed.
This move is unexpected for some, particularly those who observe the fashion choices of the high-tech billionaire in the White House. Long before someone pushes “send” on those controversial tweets or engages with Trump’s “One Big Beautiful Bill” (OBBB), Musk’s political downfall was apparent through his choice of attire.
During his time in the White House, Musk ignored the conventional dress code expected of a president’s advisor, where suits and ties are the norm. Instead, he donned a dark MAGA baseball cap in the Oval Office and proclaimed at a rally in New York: His casual T-shirts featured slogans like “Oakrochee Mars,” “Tech Support,” and “Dogefather.” Campaign commentators noted his appearance, suggesting he seemed more connected to an alternative reality than to political events. His style felt reminiscent of the K-Hall aesthetics, which Musk frequently alludes to abandoning.
Musk and his Silicon Valley peers favor casual attire, favoring loose necklines over collared shirts, often opting for padded jackets, a stark contrast to the formality observed in the U.S. capital.
Yet, while Musk’s casual clothing signaled a shift in DC power dynamics, it also challenged various norms. “In the tech sector, confusion can be seen as a badge of honor,” states DC-based image consultant and style strategist Lauren Rothman. “However, in politics, the tolerance for chaos is limited. The White House has a long-standing tradition. We won’t be moving away from suits… they are a uniform.”

In this fashion landscape, one can objectively dress poorly or inappropriately; take, for instance, Dominic Cummings. Boris Johnson’s former aide famously promoted Westminster’s 1983 Gothic horror classic “Woman in Black” while wearing a bizarre ensemble of a ripped gilet, beanie, Billabong T-shirt, and tote bag. He wasn’t merely a Tory supporter; he embodied Gothic horror.
According to Jonathan Friedland, a Guardian columnist and host of the Guardian Politics Weekly America Podcast, Cummings’ appearance at No. 10 is a testament to privilege: “He says, ‘You have to wear a uniform like a worker bee, but I’m important enough to the top guy to dress as I please.’
The same applies to Musk, whose casual wear starkly contrasts the typical suit expected in the Oval Office. As Rothman remarked, his rebellious uniform accentuates his unique status within the corridors of political power.
He was often labeled “Sloppy Steve” Bannon. On this side of the Atlantic, Friedland highlights Musk’s affinity for informal gatherings, drawing parallels to former David Cameron advisor Steve Hilton’s casual meetings.
This brings us back to the age-old question: Who gets to be sloppy? Friedland suggests Musk relished the opportunity to stand beside the president’s resolute desk, appearing as if prepared for a gamers’ competition. It served as a reminder of his substantial wealth and untraditional approach to politics.

However, the shared fashion philosophies of Cummings and Musk reflect a common political journey. The careless aesthetics hint at their inevitable decline. Trump may speak of draining the swamp, yet his Brioni suit represents its very essence. Similarly, Johnson’s disheveled hair and casual attire resembled that of a rebellious rapper.
In the end, the disdain for flamboyance is palpable. Dressing unconventionally, even when privilege is not fully acknowledged, is a guaranteed way to incite backlash. Musk noted in a February Fox interview, “He had some incredible young people working for him who dressed far worse than he did.”
Friedland remarked, “The contrast between Musk’s outfits and Trump’s cabinet members highlighted their perceived inferiority, equating them to the president’s subordinates.”

Upon receiving a diagnosis of non-Hodgkin’s lymphoma in 2023, particle physicist and Oxford University professor emeritus Frank Close underwent three weeks of radiation therapy, which provided him with a new understanding of radiation’s capabilities.
His 10-year-old grandson shared a detailed account of Emperor Bomba, a 50-megaton nuclear device tested by the Soviet Union in 1961, marking the most powerful human-made explosion. This prompted Close to elucidate the complexities of nuclear energy, highlighting its dual nature as both a power source and a peril.
A three-time winner of the British Science Writers Association Award, Close is well-versed in the intricacies of subatomic physics. His latest work, Destroyers of the World: Deep History of the Nuclear Age 1895-1965, starts with the Trinity Test Blast in July 1945, signifying the moment chemical explosions transitioned to nuclear ones. He takes readers on a historical journey beginning with 1896, when the first atomic traces sparked interest in the nuclear age.
The narrative features 19th-century scientist William Crookes, who delved into spiritualism after his brother’s death, observing “bright green clouds” in a gas-filled, charged vacuum tube. He believed he had synthesized external organisms and discovered phantoms. Theoretical physicist George Gamow is also mentioned, demonstrating that uranium can release charged alpha particles without contradicting energy conservation principles.
Close’s primary focus, however, revolves around the often-overlooked contributions of female physicists in the nuclear arena. He discusses Lise Meitner, who, despite holding a PhD, was banned from a male-only room at the University of Vienna. This didn’t thwart her efforts alongside Otto Hahn to provide X-rays for World War I injuries or her 1917 discovery of protactinium, element 91. In 1925, she was awarded the Lieven Prize, which marked a significant academic achievement.
He also highlights Elaine Joliot-Curie, the daughter of Marie Curie and Pierre Curie, who possessed her parents’ scientific prowess. In a notable scandal in 1910, Marie faced exclusion from the French Academy of Sciences due to her relationship with a married physicist. Elaine sought to defend her family’s legacy, underscoring work she conducted with her husband, Frédéric Joliot. The 1932 announcement of the neutron by James Chadwick shifted the course of nuclear physics.
Furthermore, Close examines the contributions of chemist Aida Noddack, who argued that uranium nuclei could be split into lighter isotopes but faced backlash from a male-dominated field. Noddack’s position as an industrial chemist challenged the established norms of elite nuclear physics.
In Destroyers of the World, Close also addresses the enigma surrounding Ettore Majorana, a theoretical physicist revered by Enrico Fermi, who mysteriously vanished in 1938. Speculation about Majorana’s fate has ranged from suicide to escaping fascism in Italy, but as with many similar cases, certainty eludes us.
As we navigate through the radioactive haze, one fact remains evident: many extraordinary individuals played pivotal roles in unleashing the Nuclear Demon from its confines.

Listening to the leaders of AI companies suggests that the coming decade will transform human history profoundly. We’re entering an era described as “radical abundance,” which presents an optimistic view reminiscent of groundbreaking advancements in high-energy physics and aspirations for space colonization. Yet, the experience of researchers working with today’s leading AI systems reveals a contrasting narrative. In practice, even the top-performing models struggle with basic tasks that most individuals find simple. So, who should we trust?
According to Sam Altman of OpenAI and Demis Hassabis of Google DeepMind, a transformative AI system is on the horizon. In Altman’s blog post, he predicts that the 2030s will usher in significant changes compared to prior decades, suggesting that breakthroughs in materials science might enable high-bandwidth brain-computer interfaces within just a year.
Hassabis also projects a fruitful decade ahead in an interview with Wired, claiming that artificial general intelligence (AGI) will tackle major challenges like the treatment of severe diseases, potentially leading to improved health and longevity. He confidently states, “If all this transpires…”
This ambitious outlook heavily relies on the premise that larger language models (LLMs) such as ChatGPT can effectively utilize more data and computing power. While this “scaling approach” has proven successful in recent years, signs have begun to signal a slowdown. For instance, OpenAI’s latest GPT-4.5 model demonstrated only modest gains over its predecessor, GPT-4, despite likely costing hundreds of millions to train. Such expenditures pale compared to future investments; Meta is poised to announce a $15 billion investment aimed at realizing “superintelligence.”
Yet, the sole approach to resolving these challenges isn’t merely financial. AI companies are shifting towards “inference” models like OpenAI’s O1, which was introduced last year. These models require more computational resources, taking longer to generate responses while processing their output iteratively, mimicking a human-like “thinking” process. Noam Brown from OpenAI cautioned about AI’s limitations, noting last year that both the O1 model and its iterations indicate that “scaling methods” can indeed progress.
Nevertheless, recent studies reveal that these inference models can falter even on straightforward logic challenges. Research conducted by Apple scientists found that AI models, including Deepseek’s inference model and Anthropic’s Claude Thinking model, encountered obstacles during basic tasks. The study highlighted that while the models demonstrated limitations in accurate computations, they frequently failed to apply explicit algorithms and reasoning consistently.
The researchers tested AI performance on various puzzles, including scenarios where individuals must transport items using the least number of moves, as well as the Tower of Hanoi challenge requiring sequential movement without placing larger discs atop smaller ones. Although the models could tackle simpler instances, they struggled as complexity increased. This research suggests that while more intricate problems may require longer contemplation from AI, the reduced number of “tokens” (information bundles) indicates that the apparent “thinking” time of the models may be deceptive.
“It’s concerning that these can be easily resolved,” remarked Artur Garcez from the University of London. “We mastered symbolic AI inference techniques for these tasks half a century ago.” Although enhancements and fixes could eventually enable these new systems to tackle complex problems, Garcez suggests that merely increasing the model size or computational capabilities is unlikely to be a panacea.
These models also illustrate their persistent difficulties in addressing scenarios they haven’t encountered in their training data, remarked Nicos Aletras from the University of Sheffield. “In practical terms, while they excel at information retrieval, summarization, and related tasks due to their training, they can come off as impressive without being truly adaptive,” Aletras concluded. “Apple’s research has undoubtedly highlighted a significant blind spot.”
Additionally, other research indicates that extending “thinking” duration could detrimentally affect AI model performance. Soumya Suvra Ghosal and colleagues at the University of Maryland analyzed Deepseek’s model and uncovered that prolonged “thinking chains” reduced accuracy in mathematical inference tests. In a mathematical benchmark, they found that tripling the number of tokens enhanced performance by around 5%, but using 10-15 times the tokens led to a decline of roughly 17% in scores.
In certain instances, the “chain of thought” generated by AI bears little relation to the eventual answer it provides. When testing Deepseek’s navigation abilities in a simple maze, Subbarao Kambhampati from Arizona State University discovered that even when the AI solved the issue, its “chain of thought” contained mistakes not reflected in its final answer. Moreover, presenting AI with an irrelevant “chain of thought” sometimes improved the accuracy of its responses.
“Our findings challenge the common belief that intermediate tokens or ‘thought strands’ provide a meaningful trace of internal inference in AI models,” Kambhampati stated.
All recent studies assert that the terms “thinking” and “inference” in relation to these AI models are misleading, according to Anna Rogers at the University of Copenhagen. “Many leading techniques I’ve encountered in this field have historically been accompanied by vague, cognitively-inspired analogies that ultimately proved incorrect.”
Andreas Vlachos from Cambridge University observed that while LLMs have distinct applications in text generation and other tasks, recent insights imply that Altman and Hassabis may face difficulties confronting the complex challenges they anticipate solving in the near future.
“There is an inherent conflict between their model training—predictions based on the forthcoming words—and our objectives, which involve generating true inferences,” Vlachos remarked.
On the other hand, OpenAI maintains a different stance. A spokesperson remarked, “Our research indicates that chain-like inference methodologies can significantly enhance performance on complex problems, and we are actively pursuing advancements in training, evaluation, and model design.” Deepseek has yet to comment on requests for input.
TThis resembles a sphere like Redrock, an open-world variant of Las Vegas Mind-Yay. It’s nearly directly the original concept: a massive bubble of bubbles partly embedded in the desert ground, with its exterior acting as a gigantic screen. Occasionally, cars halt beside this sphere while traveling in an electric vehicle designed by Silva, the global megascope controlling entity. They pause just as advertisements on the Silva EV unfold dramatically overhead, resulting in a slight disorienting effect.
In these instances, I truly grasp what Mind-eye aims to convey. You find yourself ensnared in the ultimate company town ruled by oligarchs and con artists who have no desire to escape the ecosystem they’ve constructed. Mindseye infiltrates this reality through serendipitous interactions with a blend of wit and lightness. While much of the game skews towards heavy-handedness and dullness, it’s refreshing to experience moments of clarity where everything falls into place.
With its sphere and ever-present EV, Mindseye embodies a futuristic vibe. It connects with themes surrounding AI, the Tech elite, and the creeping menace of corporate dystopia. You take on the role of a former priest grappling with amnesia who must confront the precise harm that technology has inflicted on his humanity, engaging in combat against people, robots, and drones. Beyond the main story, Mindseye also offers a toolkit for creating your own games and levels to share with fellow players. This all comes from a studio co-founded by Leslie Benzies, known for his work on GTA 5 and more.

Strangely, the gameplay often feels reminiscent of the past. When I move my finger through the air, I sense a breeze from around 2012. Heartfelt, it’s a somewhat clunky cover shooter set in an open world experienced primarily during travel between missions. The narrative exists mainly to justify betrayals, car chases, and shootouts, while explaining why you enter battles accompanied by personal drones that can open doors and stun nearby foes.
It can be a peculiar affair, evoking memories of a time when many third-person games included cutscenes and cover mechanics that hadn’t yet reached necessity. It’s worth noting that there are frequent reports of crashes, technical glitches, and NPCs appearing without faces. My playthrough on a relatively older PC encountered just one crash and a handful of amusing bugs, but overall, I faced minimal issues. I engage with games that feel similarly dated.
This might attract less criticism than anticipated. A straightforward run-and-gun mission lets you repeatedly photograph individuals who share a striking resemblance while choosing routes between waypoints. Shooting mechanics often provide enjoyment, so it feels somewhat disappointing to drive for each mission, though the vehicle conveys a satisfying sense of freedom, reminiscent of classic driving games. (Air travel lacks excitement due to its lack of character.)

In a world where many games contemplate AI dominance, the in-game AI around me seemed far from a takeover. When I relinquished control of the vehicle to the game while tailing an enemy, I was advised to avoid detection, leading to our bumpers colliding at each intersection. This particular open-world town is inhabited by amusingly unskilled AI drivers. I’ve frequently arrived at traffic lights only to be greeted by their reckless antics. Consequently, I often appreciated the off-screen collisions involving road cones and dumpsters that I consistently found amusing.
I even enjoyed the plot’s quirks, featuring lines like “My DNA has changed since we last met!” But do you feel it? Nevertheless, I’ve become increasingly aware that intelligent individuals devoted a considerable amount of effort to creating this game. I don’t think they aimed to disappoint. Or to place me in an open world that feels sparse, not due to a lack of mission icons or fishing mini-games, but because it lacks convincing human elements.
This issue appears to resonate thematically. It embodies a reckless ambition. When I explored the level editor, I discovered impressively rich and complex tools, but creating something truly exceptional on this platform demands significant time and dedication. This is undoubtedly aimed at mega fans with niche interests. Completing everything in the campaign (even those sections that attempt variation with stealth, tracking, and sniping segments) is an endeavor that requires a real mega-corporation’s backing.
Mindseye is peculiar. Despite its flaws, I seldom found it unenjoyable, but I still find it challenging to give an unreserved recommendation. The concepts, immediate actions, and narratives are so vaguely developed that they nearly vanish. Still, I’m somewhat glad it exists.
For centuries, humanity has been intrigued by the possibility of encountering advanced civilizations beyond our planet. But what if such a society existed on Earth long before humans evolved?
In 2018, physicist Professor Adam Frank and climate modeler Dr. Gavin Schmidt published a paper exploring whether modern science might uncover traces of an extinct industrial civilization from millions of years ago. The paper is available here.
Dubbed “Silur’s Hypothesis,” after the advanced reptilian species from the long-running BBC science fiction series Doctor Who, the researchers concluded that, while unlikely, evidence of such a civilization may be elusive.
The study focuses on the timeframe between 400 million and 4 million years ago, investigating what remnants this hypothetical society might have left behind.
Over just a few centuries, our industries have significantly altered global climate and ecosystems. If humanity were to vanish over millions of years, however, any direct evidence of our society would likely fade away.
Our largest cities could vanish within a geological instant due to erosion and tectonic activity.
Consequently, scientists searching for an ancient civilization should look for geological signatures of their existence.
Advanced civilizations, much like modern humans, would demand substantial energy and food production. As a result, we might anticipate similar indicators in Earth’s geologic layers, such as evidence of extensive carbon emissions, climate change, and rising sea levels.
Should pyramids reminiscent of alien architecture have been constructed by lost ancient civilizations millions of years ago, Silur’s Hypothesis suggests that discovering them would be quite unlikely.
The challenge lies in distinguishing climate change caused by fossil fuel-dependent civilizations from that induced by natural processes in the geological record.
Interestingly, there is a striking resemblance between current climate change and historical events on Earth referred to as “hyperthermal” events. One such instance occurred around 55 million years ago, where global temperatures surged by up to 8°C (14.4°F) and were accompanied by intense geological upheavals.
Another consideration is that the longer a sophisticated civilization endures, the more evidence it generates. However, for a civilization to have longevity, it must be sustainable, leading to reduced geological traces.
For instance, a civilization relying on wind and solar energy would leave less physical evidence compared to one powered by fossil fuels. This paradox explains why the traces of such civilizations, if they indeed existed, would be infrequent.
Silur’s Hypothesis encourages us to reflect on the imprints humanity leaves behind. Addressing these inquiries may enhance our search for advanced civilizations on other planets.
This article answers the question posed by Exeter’s Joshua Stucky: “If advanced civilizations lived on Earth millions of years ago, could we recognize their existence?”

Tracing the world’s oldest cheese is challenging, but direct evidence shows that humans have been consuming milk for millennia.
Archaeologists have discovered milk residues in ancient pottery from various locations worldwide.
Research on carbon isotopes of fatty acids from pot residues reveals that humans have been consuming milk in the UK since 4000 BC. However, in Anatolia, a region in Türkiye noted for its Neolithic agriculture, evidence suggests milk consumption dates back even earlier to around 7000 BC.
Farmers in Anatolia were widely mobile. Although milk fat residues often degrade over thousands of years underground, the sheer number of ceramic pieces found leads scientists to speculate that these early peoples were likely producing long-lasting dairy products like cheese.
When milk is transformed into cheese, lactose levels decrease, helping to mitigate lactose intolerance, which was common across Europe. It wasn’t until approximately 3,000 years ago that genetic mutations became prevalent, enabling adults to produce lactase.
A 2023 study from York University found protein structures in a Polish late Neolithic pot, suggesting it contained cheese made from the milk of cows, goats, and sheep.

The oldest cheese sample still known today is approximately 3,500 years old and was found around the neck of a Bronze Age mummy in the Xiaohe Cemetery in northwestern China.
A team at the Chinese Academy of Sciences conducted an analysis of this specimen, identifying it as kefir cheese (fermented bacterial milk). The scientists found DNA from various bacteria and yeast species, including Lactobacillus kefiranofaciens and Pichia kudriavzevii, which are present in kefir today.
They hypothesize that the lump could represent a kefir starter grain, a concentrated bacterial colony used to initiate cheese fermentation. These grains were likely regarded as valuable offerings for the afterlife in ancient times.
This article addresses the question, “What is the oldest cheese in the world?” posed by Scott Mills of Watford.

Mercury pollution resulting from early coal burning and gold mining continues to affect Arctic wildlife over a century later. New research published in Natural Communication reveals these enduring effects.
Despite worldwide efforts to limit emissions, mercury levels in apex predators like Arctic and toothed whales remain alarmingly high. Researchers attribute this persistence to legacy contamination that travels through ocean currents to the Arctic region.
A research team has analyzed more than 700 samples collected across Greenland over the last 40 years, ranging from animal tissues to ground peat. By evaluating the chemical “fingerprints” of mercury isotopes, they discovered that mercury concentrations have not declined and, in some cases, remain elevated in Arctic ecosystems.
“This provides insight into why we haven’t seen a decrease in Arctic mercury levels,” stated Professor Runeatz, a co-author of the study. “Mercury transport from significant sources like China to Greenland can take up to 150 years.”
Mercury released into the atmosphere through human activities can circulate the globe for approximately a year before settling. However, once it enters the ocean, it may persist for centuries, gradually moving northward through deep, cold currents.
For instance, Central West Greenland is influenced by Atlantic influx via the North Atlantic Arminger current, while other areas receive mercury-laden water from the Arctic current.
Beluga-like tooth whales today have mercury concentrations up to 30 times greater than before the Industrial Revolution – Getty
Currently, mercury concentrations in polar bears and toothed whales are 20-30 times higher than pre-industrial levels.
“We don’t have evidence of actual killings of top predators,” Dietz commented. According to an email from BBC Science Focus, “However, the loads in toothed whales and polar bears, along with Inuit populations in highly exposed areas, are significant enough to indicate neurological effects.”
As a potent neurotoxin, mercury can harm immune and reproductive health. Naturally occurring elements are extremely dangerous, as noted by the World Health Organization, which lists it as “one of the top 10 chemicals of major public health concern.”
The findings carry significant implications for the United Nations Mamata Treaty, a global initiative aimed at decreasing mercury pollution. While reduction of emissions is crucial, the study implies that the Arctic may require generations to see recovery.
The research team will continue to explore mercury’s impact on vulnerable Arctic ecosystems. Dietz emphasizes that modeling how long mercury takes to travel from major emitters like China to various Arctic regions could be essential for understanding long-term threats.

The intrigue surrounding the hacking deepens as researchers unveil new evidence indicating that two additional journalists were targeted by the same military-grade spyware utilized by Italy against activists.
Earlier this month, a parliamentary committee supervising the intelligence reporting agency confirmed that Italy employed mercenary spyware developed by Israel-based Paragon Solutions against two Italian activists.
Nevertheless, the same committee, which initiated an inquiry into the hacking scandal in March, stated that it could not ascertain the identities of those responsible for targeting prominent Italian investigative journalist Francesco Cancellato.
In a recent report from Citizen Lab researchers, Ciro Pellegrino, a close associate of Cancellato and head of the research outlet’s fan page, revealed that the Naples Bureau was also targeted by users of Paragon Solutions’ spyware. The Civic Research Institute reported that a third journalist, described as a “prominent European journalist,” was similarly targeted by the spyware.
This development unfolds as Paragon and the Italian government face mounting public scrutiny. Haaretz reported this week that Paragon offered to assist the Italian government in investigating the Cancellato incident; however, Italy allegedly declined the offer, with the Italian Security Agency expressing national security concerns.
The office of Meloni did not respond to requests for comment. A debate on this matter, which has sparked outrage between the Italian opposition and Brussels MEPs, is slated for June 16th in the European Parliament.
The Guardian sought comments from Paragon regarding the latest updates and referenced communication to Haaretz, where they confirmed that they had terminated their contract with the Italian government following the revelation in February that Cancellato had been targeted. The Guardian initially reported on Paragon’s contract termination with Italy in February.
Like other spyware vendors, Paragon markets cyber weapons to government clients, ostensibly for crime prevention purposes. The company asserts that it sells spyware exclusively to democratic nations and prohibits its use by journalists or members of civil society.
So, who is behind the targeting of the two journalists?
“We’ve noticed considerable efforts to reassure our customers,” stated John Scott-Railton, a senior researcher at Citizen Lab. “The journalists’ devices displayed a clear digital fingerprint indicating Paragon’s involvement. It became even more intriguing, as we found fingerprints in both instances that corresponded to the same Paragon clients.”
A report from the Copasir Parliamentary Committee disclosed that Italy’s domestic and foreign intelligence agencies had contracts with Paragon in 2023 and 2024, with the hacking software being used under prosecutor authorization. The committee noted that the spyware was deployed to investigate fugitives, suspected terrorism, organized crime, fuel smuggling, and anti-smuggling operations.
It also mentioned that pro-immigrant human rights activists like Luca Casarini and Giuseppe Caccia were surveilled not for their human rights work but due to their connections with “irregular immigrants.”
