A new study in mice suggests that a father's nicotine exposure could influence the metabolic health of his children. Researchers found that when male mice consumed nicotine, their offspring showed changes in how their bodies handled sugar, including ...

The asteroid impact that wiped out the dinosaurs didn't keep life down for long. New research shows that microscopic plankton began evolving into new species within just a few thousand years--and possibly in under 2,000 years--after the disaster. ...

A protein tied to ALS and dementia may have a much bigger role in disease than scientists realized. Researchers found that TDP43 controls a key DNA repair process, but when the protein becomes imbalanced, the repair system can spiral out of control, ...

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 revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and partially break apart to bind key DNA sequences that .. ...

Mars didn't always look like the barren world we see today. Over billions of years, the Sun's solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a frozen desert. NASA's twin-spacecraft ESCAPADE ...

NASA's Curiosity rover is investigating strange spiderweb-like ridges on Mars that may reveal a hidden chapter of the planet's watery history. These "boxwork" formations likely formed when groundwater flowed through cracks in the rock, leaving ...

Spiders and insects may not be fan favorites, but they are vital to the health of ecosystems--and scientists barely know how they're doing. Researchers found that nearly 90% of North America's insect and arachnid species have no conservation status, ...

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 ...
