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, ...

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 ...
