Hidden in volcanic lakes and deep-sea vents, scientists have discovered tough new DNA-binding proteins built to survive extreme conditions. After scanning huge genetic databases, researchers found molecules that remain stable under heat, salt, and .. ...

Researchers have created "Smart Underwear," a wearable device that measures flatulence by detecting hydrogen produced by gut microbes. Early tests suggest people may pass gas about 32 times a day--much higher than previous estimates. The device gives ...

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 ...

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 ...

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 ...

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. .. ...

Researchers studying over 8,400 colonoscopies discovered that having both adenomas and serrated polyps in the bowel can raise the risk of serious precancerous changes by up to five times. These two polyp types may represent separate cancer pathways . ...

A severe case of COVID-19 or influenza could increase the risk of lung cancer later on, according to new research. Scientists discovered that serious viral infections can alter immune cells in the lungs, leaving behind chronic inflammation that may . ...

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 .. ...

Scientists have discovered that a rare "mirror-image" version of the amino acid cysteine can dramatically slow the growth of certain cancers while leaving healthy cells largely untouched. Unlike most anticancer treatments that harm normal tissues, .. ...
