New technique for sifting data from NASA's Kepler planet-hunting mission nearly doubles the number of confirmed planets so far. Of the new batch of 715, only four have certain Earth-like characteristics.
A 12-year pause in global warming, after 20 years of rapidly rising surface temperatures, has scientists probing for the reason. Volcanic eruptions and undersea heat storage are emerging as likely explanations.
Until now, researchers have had to rely on computer simulations to explain what happens moments before the blast that rips a star apart. But NASA's orbiting X-ray observatory NuSTAR lets scientists glimpse conditions at star's core.
Crazy ants drenched in venom from fire ants can secrete a detox agent and wash themselves with it, scientists have found. But the species is likely to pose problems for the US as it eats its way through many organisms at the bottom of the food chain.
No one has come out with a hypothesis that can explain the dark streaks without water, says the lead author of a new paper assessing images and observations from Mars. But no direct evidence of water has been found.
A comprehensive look at 87 marine-protected areas, set up to protect fish populations, finds that more than half the time the ocean havens make no difference. But researchers identify five factors that seem key to improvement.
A team of scientists in Britain made the find while mapping a highland region under the West Antarctic Ice Sheet to better understand where the sheet originated and how far, under a warming climate, it might retreat.
Human-triggered climate change is real, scientists agree, but only about half of the public concurs. Part of the reason, a study says, is how people process information when confronted with complex issues.
