While Tuesday's earthquake in Chile was large by any measure, seismologists remain concerned it could have been a foreshock to a much larger quake in this region – a section of plate boundary that hasn't seen a major rupture in 137 years.
The new IPCC report documents changes already apparent due to climate change – reduced crop yields, less water in some regions, changes to natural systems. But it also cites humanity's steps to manage the rising risks.
Eight people died in the Washington mudslide, and the toll is expected to rise. No detailed hazard map exists for the country as a whole, and no national database exists of past slides and the conditions that caused them.
A research team found that over four decades, global warming has added 35 days to the wildflower season in the southern Colorado Rockies. But the team's data reveal nuances that other studies have missed.
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.
