Hair may grow in a completely different way than scientists once believed. Instead of being pushed out from the root, new research shows that moving cells inside the follicle actually pull the hair upward like a microscopic motor. Advanced 3D imaging ...

Scientists may have finally solved the mystery of strange plume-like structures hidden deep inside the Greenland ice sheet. New research suggests they form through thermal convection--slow, swirling motions driven by temperature differences inside .. ...

Cambridge scientists have discovered a light-powered chemical reaction that lets researchers modify complex drug molecules at the final stages of development. Unlike traditional methods that rely on toxic chemicals and harsh conditions, the new ...

Scientists have uncovered an enormous hidden archive of plant DNA that has endured for more than 400 million years. By comparing hundreds of plant genomes, researchers identified more than 2.3 million regulatory DNA sequences that act like genetic .. ...

Researchers have identified two gut bacteria that can produce serotonin, a key chemical that regulates bowel movements. In experiments with mice lacking serotonin, the microbes boosted serotonin levels, increased nerve cells in the colon, and ...

A newly identified Australian tree has been dubbed the "zombie" tree because it's alive but unable to reproduce. Myrtle rust repeatedly kills its young growth, stopping the species from flowering or making seeds. Scientists are scrambling to grow ...

Tiny plastic particles may be quietly threatening brain health. New research suggests microplastics--now widely found in food, water, and even household dust--could trigger inflammation and damage in the brain through multiple biological pathways. .. ...

Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel. During combustion, the water rapidly vaporizes, triggering micro-explosions that improve fuel mixing and lower combustion ...

Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of Sun-like stars billions of years ago. The journey may have carried the solar system away from the galaxy's crowded center into a ...

In medieval Denmark, people could pay for more prestigious graves closer to the church -- a sign of wealth and status. But when researchers examined hundreds of skeletons, they discovered something unexpected: even people with stigmatized diseases .. ...
