Scientists are calling for a lunar quarantine facility where samples from Mars, the Moon, and beyond would be examined before being brought to Earth. They warn that even a tiny alien microorganism could have unpredictable effects on Earth's ...

Researchers discovered that artificial streetlights can trap thousands of woodlice in mesmerizing circular "death spirals" never before seen in the wild. The surprising finding suggests that light pollution may be unintentionally altering the ...

Scientists discovered ancient wolves on a tiny Baltic island where they could only have been brought by humans, suggesting an unexpectedly close relationship between people and wolves thousands of years ago. Evidence indicates the wolves were fed, .. ...

Scientists have uncovered a hidden weakness beneath the Pacific Ocean that helps explain why Japan's catastrophic 2011 earthquake and tsunami became so devastating. By drilling deeper into the seafloor than ever before, researchers discovered a thin, ...

A stunning fossil discovery shows that ancient bees used the empty tooth sockets of mammal bones as tiny nests after owls scattered the bones across a cave floor 20,000 years ago. It's the first known evidence of bees nesting inside animal bones, ...

Scientists have uncovered new evidence that fireworks can pollute both the air and water in ways that extend beyond the visible smoke. The findings show that leftover debris, fine particles, and airborne chemicals may affect ecosystems and increase . ...

A new study found that not all geoengineering ideas are created equal. Brightening marine clouds over the eastern Pacific could dramatically weaken the El Niño cycle, triggering major changes to global weather patterns, while stratospheric aerosol . ...

Bumble bees astonished researchers by inventing a new way to reach a hidden reward, despite never being taught the trick. The discovery adds to growing evidence that these tiny insects are far smarter and more adaptable than once believed.

A pioneering climate scientist is challenging a U.S. government report that cited his research while reaching what he says is the exact opposite conclusion. Benjamin Santer and his colleagues say decades of satellite data clearly reveal the ...

Ancient asteroid impacts may have done more than reshape Earth's surface--they could have helped spark life itself. New computer models show the collisions created enormous underground hydrothermal systems by cracking the planet's crust and allowing ...
