A legendary golden fabric once worn only by emperors has made an astonishing comeback. Korean scientists have successfully recreated ancient sea silk--a rare, shimmering fiber prized since Roman times--using a humble clam farmed in modern coastal ...

Baker's yeast isn't just useful in the kitchen -- it may also be built for space. Researchers found that yeast cells can survive intense shock waves and toxic chemicals similar to those on Mars. The cells protect themselves by forming special stress ...

A new international study points to a specific brain network as the core driver of Parkinson's disease. Scientists found that this network becomes overly connected, disrupting not just movement but also thinking and other bodily functions. When ...

Your gut is home to trillions of bacteria that constantly "sense" their surroundings to survive and thrive. New research shows that beneficial gut microbes, especially common Clostridia bacteria, can detect a surprisingly wide range of chemical ...

Researchers have found a surprising way to turn sunflower oil waste into a powerful bread upgrade. By replacing part of wheat flour with partially defatted sunflower seed flour, breads became dramatically richer in protein, fiber, and antioxidants- . ...
