Ultrasound reads monkey brains, opening new way to control machines with thought
The most advanced mind-controlled devices being tested in humans rely on tiny wires inserted into the brain. Now researchers have paved the way for a less invasive option. They’ve used ultrasound imaging to predict a monkey’s intended eye or hand movements—information that could generate commands for a robotic arm or […]
This microscopic hitchhiker is a friend to both plants and humans
Soil bacteria called Streptomyces are the guardian angels of the microbial world: They produce antibiotics that humans depend on and protect plants from harmful microbes. But because neither the bacteria nor their spores can move themselves around, researchers have long puzzled over how they find the plants they protect.

Ancient Native Americans were among the world’s first coppersmiths
About 8500 years ago, hunter-gatherers living beside Eagle Lake in Wisconsin hammered out a conical, 10-centimeter-long projectile point made of pure copper. The finely crafted point, used to hunt big game, highlights a New World technological triumph—and a puzzle. A new study of that artifact and other traces of prehistoric […]
Former Senator Bill Nelson nominated to lead NASA
President Joe Biden has nominated his longtime colleague, former Senator Bill Nelson (D–FL), to lead NASA, the administration announced today. If confirmed, Nelson will be tasked with leading the country back to the Moon, while also developing an ambitious project to recover the rock samples drilled by the Perseverance rover […]
Some dead stars may harbor enough uranium to set off a thermonuclear bomb
A thermonuclear bomb might be ticking deep in the cores of some dead stars. A new theoretical study traces out how certain stellar corpses known as white dwarfs could accumulate a critical mass of uranium that would trigger a massive supernova explosion.
