What would Bill Nye the Science Guy get our home planet for Earth Day? The ultimate gift: fusion energy. “We need electricity,” Nye told Live Science in an exclusive interview on Thursday (April 20). “We need not only what we can get right now with existing technologies — with wind, and solar and geothermal energy … Read more
The moon’s orbit around Earth appears so regular that civilizations have based the month on lunar motion for thousands of years. However, the moon is actually creeping slowly away from Earth. So will Earth lose its moon at some point? Scientists determined the rate at which the moon is drifting away from Earth with help … Read more
Elite women, perhaps princesses, played a crucial role in holding the Xiongnu, one of the first nomadic empires of the eastern Eurasian Steppe, together, a new study suggests. The Xiongnu, who may have been among the ancient ancestors of the Mongols, formed a confederation of nomadic peoples who controlled much of Central Asia, from present-day … Read more
The Vikings are remembered as fierce fighters, but even these mighty warriors were no match for climate change. Scientists recently found that ice sheet growth and sea level rise led to massive coastal flooding that inundated Norse farms and ultimately drove the Vikings out of Greenland in the 15th century. The Vikings first established a … Read more
The asteroid that wiped out the dinosaurs did not trigger a long-lasting impact winter, scientists have found — a discovery that raises new questions about what happened on Earth just after it hit. One spring day 66 million years ago, a 6-mile-wide (10 kilometers) asteroid smashed into the Yucatán Peninsula and upended life on Earth. … Read more
An ethereal whirlpool of light recently appeared in the night sky above Alaska, briefly stealing the limelight from a strong auroral display. But the bizarre, spiral-shaped object had nothing to do with the dancing polar lights. Instead, the luminous vortex was just the latest example of what astronomers have nicknamed “SpaceX spirals,” which are becoming … Read more
Gravity can turn itself into light, but only if space-time behaves in just the right way, a research team has found. Under normal circumstances, you cannot get something from nothing. Specifically, the Standard Model of particle physics, the reigning theory that explains the subatomic zoo of particles, usually forbids the transformation of massless particles into … Read more
Human beings can generate false memories of events mere seconds after they have occurred, a new study has found. The phenomenon, which researchers have dubbed “short-term memory illusions,” shows how easily and rapidly humans reimagine experiences to fit our preconceptions, rather than accurately recording what takes place. The researchers published their findings April 5 in … Read more
From the creepiest Cambrian critters to massive marine reptiles, wonderfully weird sea creatures have inhabited our oceans for over half a billion years. We’ve put together a list of 25 of the strangest ancient sea monsters ever to have lived, all of which went extinct long before humans came along. The only reason we know … Read more
Sixty million years ago, when the Eurasian plate slammed into the Indian plate, a mountain range was born. Because these plates were of similar density, neither could sink below the other. The rocks had nowhere to go but up. Now, the Himalayas host Earth’s tallest mountains. Mount Everest is the tallest, towering 5.4 miles (8.8 … Read more
