So much for that theory. Welcome to the world’s first plague cemetery The Angara River flows from the depths of Lake Baikal. The people who lived along it thousands of years ago survived by hunting, foraging, and fishing. They would have lived in relatively small groups, but they seem to have stayed connected across hundreds ..

Last week, we looked at a new study of the origin of complex cells, one that showed that our ancestors’ genomes were pieced together from bits and pieces of multiple species. It put a spotlight on a phenomenon called horizontal gene transfer, in which a gene from one species is incorporated into the genome of ..
Early in the 11th century, a young Benedictine monk named Eilmer jumped from the 150-foot tower of his abbey in the small English town of Malmesbury, wearing a pair of crude wings he’d fashioned from willow wood and cloth. Eilmer managed to glide a good 600 feet, passing over the city wall before crash-landing in ..
The study only covers living arbuscular mycorrhizal fungal networks, Stewart said, and doesn’t include dead fungal networks, which also help to store carbon and add to the total biomass and influence of the networks on ecosystems. Research into dead fungal networks is still being explored. The study also found where these networks are most threatened. ..
That doesn’t mean the error-corrected qubit was fully stable. Eventually, one of the errors that inevitably occurred couldn’t be recovered from because too many of its individual atoms changed state at once. But performing normal error correction could keep some of these logical qubits stable for up to 90 rounds. Again, that’s not good enough ..
At the same time, the plants unable to detect the molecular signature of the caterpillar’s drool were largely ignored by the wasps. They weren’t completely defenseless, though. “There are other papers that show if you knock out all immune signaling, the caterpillars grow twice as big—they get enormous,” Steinbrenner says. This, he suggests, indicates the ..
When the team returned to the sites, they determined which decorations had been selected from the slush pile and moved to a bower, and whether it came from an urban or rural source. After recording the data, all the original decorations were returned to their bowers. Green glass and red wire A male great bowerbird ..
One way archaeologists learn how ancient people, including Neanderthals, did things is to attempt to do those things themselves, a process called experimental archaeology. Normally, that involves making stone tools, butchering deer, or distilling birch tar. But in a new study, it meant doing very destructive things to teeth from one of the world’s most ..
By early March, a government program director was telling UCAR that he needed to “get this done quickly” and that documentation of the supercomputing center needed to be handed over “yesterday.” Even now, months after the deadline for public feedback on the decision, the government admits it hasn’t fully evaluated the comments it received. “The ..
They also conducted experiments that tracked people’s eye movements and recorded their brain activity as they viewed sets of images—both in the lab and in a gallery. There was more stable integrative brain processing when people looked at real art versus pseudo-art, and the eye movements mapped neatly onto the previously identified topological features, suggesting ..
