Hackers, take notice: Ultrasecure quantum video chats are now possible across the globe. In a demonstration of the world’s first intercontinental quantum link, scientists held a long-distance videoconference on September 29 between Austria and China. To secure the communication, a Chinese satellite distributed a quantum key, a secret string of numbers used to encrypt the […]
When it comes to some operations, surgical robots may not be worth the extra time or money. Researchers compared patients who underwent traditional laparoscopy to have a kidney removed — surgery involving several small incisions rather than one large cut — with patients who received robot-assisted laparoscopies. Although the two groups had similar complication rates […]
The wind is helping to awaken one of Antarctica’s sleeping giants. Warm ocean waters, driven inland by winds, are undercutting an ice shelf that holds back a vast glacier from sliding into the ocean, researchers report November 1 in Science Advances. Totten Glacier is East Antarctica’s largest glacier, with a drainage basin encompassing about 550,000 […]
The asteroid collision that may have doomed the dinosaurs 66 million years ago really stank. A new analysis of gases released from vaporized rocks at the impact site in modern-day Mexico suggests that the smashup released up to three times more smelly, climate-cooling sulfur than previously believed. The Chicxulub impact spewed about 325 billion tons […]
It may have walked like a duck and swum like a penguin, but a flipper-limbed creature discovered in what is now Mongolia was no bird. The strange new species is the first known nonavian dinosaur that could both run and swim, researchers say. To compensate for a long swanlike neck, probably used for dipping underwater […]
One of the top stories of 2016 quietly exited much of the public’s consciousness in 2017. But it’s still a hot topic among scientists and for good reasons. After Zika emerged in the Western Hemisphere, it shook the Americas, as reports of infections and devastating birth defects swept through Brazil and Colombia, eventually reaching the […]
NEW ORLEANS — National flood maps are underestimating the risk for tens of millions of people in the United States. That’s the conclusion of researchers presenting a new study December 11 at the American Geophysical Union’s fall meeting. The U.S. Federal Emergency Management Agency estimates that about 13 million people live in a “1-in-100-year” floodplain […]
Living near a fracking site appears to be detrimental to infant health, a study eyeing the gas production practice in Pennsylvania suggests. Babies of moms living within one kilometer of a hydraulic fracturing, or fracking, site in the state had a 25 percent greater chance of being born underweight than did babies whose moms lived […]
An astonishing number of things that scientists know about brains and behavior are based on small groups of highly educated, mostly white people between the ages of 18 and 21. In other words, those conclusions are based on college students. College students make a convenient study population when you’re a researcher at a university. It […]
It doesn’t matter if it’s a burly rattler or a tiny garter snake. A deadly fungal disease that’s infecting snakes in the eastern and midwestern United States doesn’t appear to discriminate by species, size or habitat, researchers report online December 20 in Science Advances. The infection, caused by the fungal pathogen Ophidiomyces ophiodiicola, can cover […]
