Hundreds of people died across Asia in recent weeks as the region sweltered under blistering temperatures. And a new study determined a leading factor in how it all happened. Last month, many areas in India saw temperatures well above triple digits. The country’s meteorological service says that heat waves are not uncommon between March and […]
When the first warm-blooded dinosaurs roamed Earth
DALLAS (AP) — Scientists once thought of dinosaurs as sluggish, cold-blooded creatures. Then research suggested that some could control their body temperature, but when and how that shift came about remained a mystery. Now, a new study estimates that the first warm-blooded dinosaurs may have roamed the Earth about 180 million years ago, about halfway […]

Black holes are mysterious, yet also deceptively simple − a new space mission may help physicists answer hairy questions about these astronomical objects
Physicists consider black holes one of the most mysterious objects that exist. Ironically, they’re also considered one of the simplest. For years, physicists like me have been looking to prove that black holes are more complex than they seem. And a newly approved European space mission called LISA will help us with this hunt. Research […]
Viruses are doing mysterious things everywhere – AI can help researchers understand what they’re up to in the oceans and in your gut
Viruses are a mysterious and poorly understood force in microbial ecosystems. Researchers know they can infect, kill and manipulate human and bacterial cells in nearly every environment, from the oceans to your gut. But scientists don’t yet have a full picture of how viruses affect their surrounding environments in large part because of their extraordinary […]

Big decision! Curiosity rover keeps following possible Mars river remnant
For the past month, NASA’s Curiosity rover has been shadowing Gediz Vallis, a channel that scientists think may be the fossil of an ancient Martian river. Last week, Curiosity reached the north side of Pinnacle Ridge, part of a rock wall that looms over Gediz Vallis. In fact, after Curiosity navigated bumpy ground to do […]
