Brookhaven Lab scientists create promising gold-indium oxide nanoparticles through room-temperature oxidation
It’s common wisdom that one rotten apple in a barrel spoils all the other apples, and that an apple ripens a green banana if they are put together in a paper bag. Ways to ripen, or spoil, fruit have been known for thousands of years—as the Bible can attest—but now the genes underlying these phenomena of nature have been revealed.
University of Washington researchers have demonstrated that when humans use brain-computer interfaces, the brain behaves much like it does when completing simple motor skills such as kicking a ball, typing or waving a hand. Learning to control a robotic arm or a prosthetic limb could become second nature for people who are paralyzed.
