Wind and solar energy remain the only obvious replacements for fossil fuels, but recent research shows that scientists are clearly thinking outside the box to come up with future alternatives. They have recently been able to report at least theoretical progress with nuclear energy, algae and a novel alloy. In just a few days, they […]
Researchers in England announced on Monday the discovery of a major prehistoric stone monument less than two miles away from Stonehenge. The researchers are calling the collection of stones a “super-henge” because it’s nearly a mile wide, “dwarfing Stonehenge by a factor of 12,” says IFL Science. A bigger Stonehenge? Archaeologists have discovered larger stone remains near […]
Scientists working in the desert badlands of northwestern Kenya have found stone tools dating back 3.3 million years, long before the advent of modern humans, and by far the oldest such artifacts yet discovered. The tools, whose makers may or may not have been some sort of human ancestor, push the known date of such […]
An international collaboration of scientists has just completed the ultimate green census—by calculating that the planet is home to 3.04 trillion trees. The latest estimate is far higher and almost certainly more accurate than any previous attempt. But the bad news is that humans are removing trees at the rate of 15 billion a year—and […]
New research underway indicates that at least three feet of global sea level rise is near certain, National Aeronautics and Space Administration (NASA) scientists warned Wednesday. Sea levels have already risen 3 inches on average since 1992, with some areas experiencing as much as a 9-inch rise. Photo credit: NASA / Saskia Madlener That’s the higher […]
With the world’s glaciers melting at record rates, the Jakobshavn—Greenland‘s fastest-moving glacier and one of the fastest melting in the world—may have lost its largest chunk of ice in recorded history.

When scientists classify fruits, vegetables and nuts, it all comes down to anatomy. But in popular culture, we often get it all mixed up calling fruits vegetables and vegetables fruits. Thankfully, the good people at SciShow are here to clear things up. They’ve put together a video that explains how common produce items should really be classified. Sure, […]
One of the best meteor showers of the year—the Perseids—will delight stargazers this week. “If you see one meteor shower this year, make it August’s Perseids or December’s Geminids,” NASA says. “The Perseids feature fast and bright meteors that frequently leave trains, and in 2015 there will be no moonlight to upstage the shower.” Plus, August is […]
Goodbye freeze-dried space food. NASA’s astronauts aboard the International Space Station are taking a giant leap with its menu: fresh-grown vegetables. 3 astronauts will harvest and taste space-grown lettuce today at 11:15am on @NASA TV… http://t.co/C7LVQGyw5P pic.twitter.com/kFNvikrV2z — Intl.
