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 ...

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 ...

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 . ...

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 ...

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 ...

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 .. ...

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 ...

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 .. ...

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 ...

Why do some people stay mentally sharp even when their brains show signs of Alzheimer's disease? Scientists in the Netherlands may have uncovered an important clue hidden in a rare group of immature brain cells. Researchers discovered that these ...
