The U.S. Southwest Could Soon Experience Decades-Long "Megadroughts"

During the 1930s, America's High Plains were ravaged by an 8-year long drought, resulting in the dreaded Dust Bowl. Scientists now warn that, owing to global warming, this could happen again — and that by next century many parts of the world could experience "megadroughts" lasting for several decades. » 8/28/14 8:00am Thursday 8:00am

Should We Be Exploring The Oceans Instead Of Space?

For some, the irony is almost too much to bear. While Congress is eager to fund a $2 billion expedition to search for oceans beneath Europa, some 95% of Earth's oceans are unexplored.

Climate-change deniers like to remind us how, in the 1970s, scientists all believed the Earth was heading for another ice age. So why should we believe the doomsayers who now claim the opposite? Here's why: Most scientists rejected the "global cooling" theory and, even then, were convinced the real problem was… » 8/08/14 11:00am 8/08/14 11:00am

Hydrothermal Vent Mining Is Almost A Thing

Deep sea hydrothermal vents, home to exotic forms of life that exist nowhere else on earth, are very close to being commercially mined for precious and rare-earth metals. This could have profound effects on the isolated ecosystems surrounding the vents, some of which have existed for millennia. » 7/30/14 12:59am 7/30/14 12:59am

High Levels of Insecticide Found in Iowa Streams

A study released today offers evidence that neonicotinoids, the same pesticides associated with honeybee deaths, are now flowing into our water supplies. Neonicotinoids are a kind of insecticide that some scientists say could be causing colony collapse disorder, which endangers bees and agricultural plants alike. » 7/25/14 3:47pm 7/25/14 3:47pm
