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 ...

Hair may grow in a completely different way than scientists once believed. Instead of being pushed out from the root, new ...

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 ...

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 ...

Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of ...

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 ...

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 ...

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 ...

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 ...

Tiny plastic particles may be quietly threatening brain health. New research suggests microplastics—now widely found in food, ...

Scientists have found a promising new way to manufacture one of industry’s toughest materials—tungsten carbide–cobalt—using advanced 3D printing. Normally, producing this ultra-hard material requires ...

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 ...
