New research has begun to unravel the mystery of why bees are disappearing in alarming numbers worldwide: Some of the pesticides most commonly used by farmers appear to be changing bee behavior in small but fatal ways.
Long before Jeff Bezos became an Internet mogul, he was enthralled by the mysteries of space.
A new report says places from Mumbai to Miami need to prepare for more severe storms, droughts and heat waves.
In James Cameron's fantasy films, like "Avatar" and "The Abyss," the unexplored is splashed in color and fraught with alien danger. But on his dive to the deepest place on Earth, reality proved far different: white, barren and bland.
Researchers have found that coastal mists may carry toxic mercury that can harm ecosystems and human health.
The smallest planet in the solar system keeps serving up big surprises. A team led by geophysicist Maria Zuber of the Massachusetts Institute of Technology reported in the journal Science that the team found the planet's surface to be unusually flat when compared with the terrain of the moon or Mars. Messenger mission scans also showed that in the 960-mile-wide Caloris impact basin, the northern part of its floor is higher than the south, with parts standing higher than its rim. This lopsidedness may have resulted from tectonic forces -- and is one of a growing number of clues that Mercury may have been geologically active more recently than previously thought. Other MIT researchers found that the core is even larger than they thought -- encompassing 83 percent of Mercury's radius. (Earth's core is a little more than half of its radius.) Perhaps most oddly of all, there must be a solid layer of iron sulfide lying between Mercury's liquid outer core and its thin mantle. It all helps scientists to better understand what could make potentially habitable planets beyond our solar system. LOS ANGELES TIMES
Japanese officials estimated last year that the March 11 tsunami washed up to 25 million tons of stuff, from cars to bottle caps, into the ocean. Most of it sank just off the Japanese coast, leaving 1 million to 2 million tons to float across the sea.
If that ice disappears, sea level could rise 23 feet.
Now, researchers have sequenced the complete genome of the iceman, nicknamed Oetzi, and discovered even more intriguing details: that he had brown eyes and brown hair, was lactose intolerant and had Type O blood.
A new study suggests that patients receiving an organ that's less than a perfect match can be protected against rejection by a second transplant -- this time of the organ donor's imperfectly matched stem cells.
Even dinosaurs can look sharp in basic black, and downright iridescent. An unusual crowlike dinosaur -- which really doesn't look like a dinosaur at all -- had glossy black feathers that were probably used to call attention to itself and find a mate, scientists say in Thursday's journal Science.
One of the strongest solar storms in years engulfed Earth early Thursday, but scientists say the planet may have lucked out.
