Cancer rates are rising in adults under 55, and new research suggests accelerated biological aging may be one piece of the puzzle. Scientists found that people from more recent generations tended to have bodies that appeared biologically older than . ...

Scientists have discovered that the brain's short-range wiring may help protect cognition even as gray matter shrinks with age. Healthier connections just beneath the brain's surface were linked to better language skills and appeared to weaken the .. ...

A foundational chemistry concept found in textbooks for almost 100 years may have been taught incorrectly. Researchers say the inductive effect in neutral molecules appears to extend only across one chemical bond, rather than gradually weakening over ...

A wearable device has revealed nighttime hormone surges that may expose a frequently missed cause of high blood pressure. The discovery could help explain why primary aldosteronism often escapes standard blood tests and point toward a more accurate . ...

Captive-raised saltwater crocodiles released into Bangladesh's Sundarbans surprised scientists by settling into the wild rather than trying to return to their breeding facility. The result suggests that releasing larger, mature captive crocodiles ...

A World War I submarine wreck off Denmark is leaking TNT into the surrounding water, seabed, and marine life more than a century after it sank. Scientists warn that thousands of similar wrecks could pose growing environmental risks as they continue . ...
