A new Finnish study reveals that just 30 minutes in a sauna can temporarily flood the bloodstream with additional white blood cells, potentially helping the immune system patrol the body and detect threats. The surprising response resembles the immune boost seen during exercise and may help explain some of the health benefits linked to sauna bathing.

Scientists have developed a new technology that could make electric vehicle batteries smaller, lighter, and longer-lasting, potentially allowing cars to travel farther on a single charge. By borrowing precision manufacturing techniques from computer chip production, they found a way to prevent damaging lithium buildup that has held back next-generation batteries.

Researchers have discovered a surprising hidden ability in Europe's familiar black-and-yellow fire salamanders: they glow green and cyan under ultraviolet light. The mysterious fluorescence comes mainly from glands in their skin and their toxic secretions, which can continue glowing for more than 24 hours after being released.

Scientists have uncovered a hidden defense mechanism in aging muscles that sacrifices strength to protect cells from damage. In mice, partially restoring a crucial molecule reversed signs of muscle wasting and prevented premature death, raising hopes for new treatments for age-related muscle decline.

Antarctica’s Thwaites Glacier may be melting twice as much as previously predicted, even without additional global warming. Scientists discovered that warm ocean water is penetrating miles beneath the ice, weakening its foundations and accelerating its retreat. A new model predicts that the glacier could add up to 30 millimeters to global sea levels by 2100, with a 60% chance of losing a crucial …

NASA’s Artemis I mission has revealed that cosmic radiation near the Moon is higher than in Earth orbit, but not by as much as scientists might expect. Tiny experimental detectors also uncovered surprising details about how radiation passes through the human body, offering valuable insights for future lunar exploration.

Scientists have uncovered a long-lost volcanic system in Iran that dates back roughly 100 million years, revealing a hidden chapter in Earth's tectonic history. The discovery sheds new light on the disappearance of an ancient ocean and the powerful geological forces that reshaped the Middle East.

Scientists have uncovered a surprising connection between Earth's opposite poles that may help explain how the planet plunged into past ice ages. New research suggests that as massive ice sheets expanded across the Northern Hemisphere, they cooled Atlantic Ocean waters that eventually traveled south toward Antarctica. This cooling may have disrupted Southern Ocean circulation, allowing the ocean …

A new clinical trial suggests that a simple daily fiber supplement could significantly reduce knee osteoarthritis pain, improve muscle strength, and make the body less sensitive to pain. Researchers discovered that the benefits may be linked to changes in gut bacteria and the hormone GLP-1, revealing a promising new approach to arthritis relief.

A major new study reveals that autistic children’s brains process faces differently, and those differences may begin earlier than scientists previously thought. Researchers found that brain signals associated with recognizing faces become more specialized as neurotypical children grow older, but show much less change in autistic children. The discovery could help explain why some autistic people …

Scientists at McGill University have discovered a surprising new ability of immune cells that could change how we understand long-term immunity. Researchers found that T cells can actually sense how stiff their surrounding tissues are, using these physical signals to help determine whether they develop into long-lasting memory cells that protect against future infections.

The asteroid that killed the dinosaurs may have set the stage for ants to conquer the planet, with a surprising boost from “jumping genes” hidden in their DNA. Scientists discovered that bursts of activity from these mobile genetic elements coincided with the rise of major ant groups and may have helped sharpen their extraordinary ability to communicate through smell.

Scientists have discovered that low testosterone and a high-fructose diet can work together to worsen fatty liver disease in mice. Unexpectedly, changes in gut bacteria appear to drive this harmful interaction, revealing a potential new target for preventing liver damage.

The secret to aging more slowly may be hiding in your gut. Scientists discovered that certain gut bacteria are strongly linked to how quickly the body ages, with microbial differences accounting for about 15% of the variation in biological aging rates. Some bacterial species were associated with slower aging, while others were linked to accelerated aging.

A surprising discovery reveals that widely used anti-inflammatory drugs may unintentionally help dangerous viruses spread through the body. Scientists found that JAK inhibitors, prescribed for rheumatoid arthritis and other inflammatory diseases, can weaken a crucial immune defense against influenza, COVID-19, and other infections. By suppressing genes that normally fight viruses, these medicatio…
