Researchers at Johns Hopkins Medicine report that they have successfully used a “zap-and-freeze” method to capture rapid communication between brain cells in living tissue from both mice and humans. The approach allowed them to observe interactions that normally happen too quickly to track. According to the team, the findings, published…

Neuroscientists at the University of Cambridge report that the human brain moves through five “major epochs” as it rewires itself from early development to late old age. Each stage reflects a different way the brain supports thinking, learning, and behavior as we grow, mature, and eventually experience age-related decline. A…

Two decades of satellite and GPS data show the Thwaites Eastern Ice Shelf slowly losing its grip on a crucial stabilizing point as fractures multiply and ice speeds up. Scientists warn this pattern could spread to other vulnerable Antarctic shelves. Source link

In September 2021, a team of specialists traveled to one of the least-documented areas of the Bolivian Amazon: the Great Tectonic Lakes of Exaltación in the department of Beni.

Sunlight plays an important role in human health because it helps the body synthesize essential nutrients such as vitamin D. At the same time, spending too long in the sun can greatly increase the likelihood of developing skin cancer. In a new study in Nature Communications, scientists at the University…

The first Bible to include a map of the Holy Land appeared in 1525, exactly 500 years ago. The map had a major flaw: it was printed the wrong way round, showing the Mediterranean to the East. Despite this error, a new Cambridge study explains that the map’s appearance in…

A new study published November 26, 2025 in the open-access journal PLOS One reports that the well-known stone figures of Rapa Nui (Easter Island) were created by many separate carving groups. The research team, led by Carl Philipp Lipo of Binghamton University, New York and colleagues, examined how these communities…

Vision guides an animal’s actions, but new research from MIT shows that the relationship goes both ways. The study, published November 25 in Neuron, reports that behavior and internal conditions directly influence how visual information is processed. In mice, the brain’s prefrontal cortex, which serves as a major center for…

Every day, the brain turns passing impressions, creative sparks, and emotional experiences into lasting memories that shape our identity and guide our decisions. A central question in neuroscience has been how the brain determines which pieces of information are worth storing and how long those memories should remain. Recent findings…

New research from the University of St Andrews reports that some coastal regions are on track to become far more acidic than scientists once believed. As additional atmospheric CO2 enters the air, it dissolves into the ocean more quickly than anticipated, driving a rapid drop in pH that threatens coastal…

A recently analyzed fossil from Devon is giving scientists a rare look at what the earliest members of the lizard lineage may have looked like, and the findings come with several unexpected twists, according to researchers at the University of Bristol. The work was published in Nature. Today, lizards and…

In a new paper in Science, researchers from the University of Chicago describe how, about 66 million years ago, the bodies of the duck-billed dinosaur Edmontosaurus annectens were transformed into remarkably detailed dinosaur “mummies” that preserved tiny features of skin, scales, and hooves. The team names the process “clay templating.”…

Belgian researchers from VIB and Ghent University (UGent), working with partners in Denmark, have found strong evidence that infection with respiratory syncytial virus (RSV) early in infancy sharply raises the likelihood of developing childhood asthma. The effect is especially pronounced in children who have a family history of allergies or…

Women who experience continuing thyroid hormone irregularities throughout pregnancy may face a higher chance of having a child diagnosed with autism, according to a study released in The Journal of Clinical Endocrinology & Metabolism. Thyroid hormones supplied by the mother play an important role in fetal neurodevelopment. When these hormones…

New findings from scientists at the American Museum of Natural History and the Smithsonian’s National Museum of Natural History show that most dogs alive today retain small but measurable amounts of wolf ancestry that developed after domestication. These lingering wolf genes appear to have influenced characteristics such as body size,…

Life online remains vulnerable. Criminals can infiltrate bank accounts or steal personal identities, and AI is helping these attacks become more sophisticated. Quantum cryptography offers a promising defense by using the rules of quantum physics to secure communication against eavesdropping. Even so, building a functioning quantum internet still involves major…

In the summer of 2022, only a few weeks after the James Webb Space Telescope (JWST) began delivering its first scientific images, astronomers noticed an unexpected pattern: tiny red points scattered throughout the new observations. These extremely compact, distinctly red objects appeared with remarkable clarity thanks to JWST’s sensitivity, and…

In the early 1930s, Swiss astronomer Fritz Zwicky noticed that many galaxies were moving far faster than their visible mass should permit. This unusual motion led him to propose that some kind of invisible structure — dark matter — was supplying the extra gravitational pull needed to keep those galaxies…

Right now, 68 million Americans have a deadline coming up: the deadline to decide their Medicare health coverage for next year if they’re over age 65 or have major disabilities. They must make those decisions by December 7, for coverage beginning January 1, 2026, which makes this time, known as…

For many people, a glass of beer feels incomplete without a thick, creamy layer of foam resting on top. Yet anyone who enjoys beer knows that this foam often disappears quickly, collapsing before the first sip. Some varieties, however, manage to hold their foam for a surprisingly long time. Researchers…

People invest significant time and effort into keeping their skin looking young through masks, creams and serums. Researchers have now identified naturally produced molecules with anti-aging potential that originate within the body itself.
