Researchers find key to Antarctic ice loss blowing in the north wind
2025-09-10
Most of the Earth’s fresh water is locked in the ice that covers Antarctica. As the ocean and atmosphere grow warmer, that ice is melting at a startling pace with sea levels and global currents changing in response. To understand the potential implications, researchers need to know just how fast the ice is disappearing, and what is driving it back.
The West Antarctic ice sheet, an unstable expanse bordering the Amundsen Sea, is one of the greatest sources of uncertainty in climate projections. Records indicate that it has been steadily shrinking since the 1940s, but key details are missing. Using environmental data gathered from ice samples, tree rings and corals, ...
Ten years after the discovery, gravitational waves verify Stephen Hawking's Black Hole Area Theorem
2025-09-10
EMBARGOED UNTIL 8AM PACIFIC TIME/11AM EASTERN TIME, SEPTEMBER 10
On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to reach us at the speed of light—but it was not made of light. It was a different kind of signal: a quivering of space-time called gravitational waves, first predicted by Albert Einstein 100 years prior. On that day 10 years ago, the twin detectors of the Laser Interferometer Gravitational-Wave Observatory ...
Researchers uncover potential biosignatures on Mars
2025-09-10
A new study co-authored by Texas A&M University geologist Dr. Michael Tice has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA’s Perseverance rover.
The findings, published by a large international team of scientists, focus on a region of Jezero Crater known as the Bright Angel formation — a name chosen from locations in Grand Canyon National Park because of the light-colored Martian rocks. This area in Mars’ Neretva Vallis channel contains fine-grained mudstones rich in oxidized iron (rust), phosphorus, sulfur and ...
Built to learn: how early brain structure primes the brain to learn efficiently
2025-09-10
Vision happens when patterns of light entering the eye are converted into reliable patterns of brain activity. This reliability allows the brain to recognize the same object each time it is seen. Our brains, however, are not born with this ability; instead, we develop it through visual experience. Collaborating scientists at MPFI and the Frankfurt Institute for Advanced Studies have recently discovered key circuit changes that lead to the maturation of reliable brain activity patterns. Their findings, published in Neuron this week, are likely generalizable beyond vision, providing a ...
Cells use electricity to eliminate their ‘weakest’ neighbours to maintain healthy protective barriers
2025-09-10
Researchers have uncovered a surprising role for electricity in keeping our body’s protective cell layers healthy.
Cells bumping against one another use electricity to identify which of their neighbours has the least energy to kill them.
The King’s College London study in partnership with the Francis Crick Institute provides insight into diseases including cancer and stroke, where cellular energy levels can be disrupted, preventing the maintenance of healthy cell numbers.
Epithelial cells, which line all organs in the body, turnover rapidly to maintain a tightly packed protective layer. They undergo a process called ‘extrusion’ ...

What motivates runners? Focusing on the “how” rather than the “why”
2025-09-10
As attention turns to this year’s New York City Marathon, observers will again ask a long-standing question: What do athletes draw upon when trying to complete this 26.2-mile run, especially at those stretches when finishing seems impossible?
Many might think that when fatigue sets in, the key to perseverance is reminding oneself why the effort is worth it or focusing on reasons why they set the goal—intuition that lines up with motivational posters, sports psychology clichés, and coaching advice. ...
Researchers capture new antibiotic resistance mechanisms with trace amounts of DNA
2025-09-10
URBANA, Ill. — Scientists from the University of Illinois Urbana-Champaign have developed a method to isolate genes from amounts of microbial DNA so tiny that it would take 20,000 samples to weigh as much as a single grain of sugar. In a new paper, the researchers discovered previously unknown antibiotic resistance genes in bacterial DNA isolated from human stool and from fish tanks at Chicago’s Shedd Aquarium.
“With antibiotic resistance on the rise, it’s more important than ever to understand the full diversity of mechanisms bacteria may ...

State school finance reforms increased racial and ethnic funding inequities, new study finds
2025-09-10
Washington, September 10, 2025—State school finance reforms designed to close funding gaps between high- and low-income districts did not reduce racial and ethnic funding inequities and in some cases increased them, according to new research. As school desegregation efforts slowed in the decades following the 1980s, these findings highlight the limitations of income-based approaches in addressing racial funding disparities in education.
The study, by Emily Rauscher of Brown University and Jeremy E. Fiel of Rice ...

An exploding black hole could reveal the foundations of the universe
2025-09-10
AMHERST, Mass. — Physicists have long believed that black holes explode at the end of their lives, and that such explosions happen—at most—only once every 100,000 years. But new research published in Physical Review Letters by physicists at the University of Massachusetts Amherst has found a more than 90% probability that one of these black-hole explosions might be seen within the decade, and that, if we are prepared, our current fleet of space and earthbound telescopes could witness the event.
Such an explosion would be strong evidence of a theorized but never observed kind of black hole, called a “primordial black hole,” ...

“Want to, but can’t”: A new model to explain the gap in waste separation behavior
2025-09-10
Household waste constitutes 30–40% of municipal solid waste globally. Separating waste at the household level into compostable, recyclable, and non-recyclable is a crucial first step for local governments to process solid waste effectively. However, large gaps between a person’s willingness to separate waste and actually separating waste have been seen across the world. Understanding the factors that affect people’s intention and behavior of separating household waste can help create more effective policies regarding household-level waste separation.
However, ...

“There are very few issues with this level of bipartisan support in today’s polarized policy environment, but the message from parents and other adults in our poll was clear and crossed party lines. Adults are worried about the impacts of smartphones and social media on children’s learning and mental health,” said the survey’s authors, Kelli ...
Study finds critically endangered sharks being sold as food in U.S. grocery stores
2025-09-10
A new study from the University of North Carolina at Chapel Hill has uncovered that shark meat sold in U.S. grocery stores, seafood markets, and online vendors often comes from endangered species and is frequently mislabeled. Researchers purchased and DNA barcoded 29 shark meat products to determine their species identity, finding that 93% of samples were ambiguously labeled and included meat from 11 different shark species.
Among the species identified were the great hammerhead and scalloped hammerhead, both listed as critically endangered by the International Union for Conservation of Nature (IUCN). Despite global ...
Meat from critically endangered sharks is commonly sold under false labels in the US
2025-09-10
Sharks have been around for more than 450 million years, but these days they are in deep trouble. Since the 1970s, shark populations have gone down by more than 70% due to unsustainable practices such as shark finning, bycatch, and overfishing, habitat destruction, pollution, and climate change. The International Union for the Conservation of Nature (IUCN) has estimated that of the approximately 550 species of sharks in existence, 14% are vulnerable, 11% endangered, and 12% critically endangered. As a result, 74 species of shark are considered at risk by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), meaning that ...
