Scientists built an AI co-pilot for prosthetic bionic hands

Managing each finger separately can, with the right sensors, ease control issues. Modern bionic hand prostheses nearly match their natural counterparts when it comes to dexterity, degrees of freedom, and capability. And many amputees who tried advanced bionic hands apparently didn’t like them. “Up to 50 percent of people…

No sterile neutrinos after all, say MicroBooNE physicists

There’s a less than 5 percent chance that earlier anomalies can be explained by fourth neutrino “flavor.” Since the 1990s, physicists have pondered the tantalizing possibility of an exotic fourth type of neutrino, dubbed the “sterile” neutrino, that doesn’t interact with regular matter at all, apart from its fellow…

This is the oldest evidence of people starting fires

We didn’t start the fire. (Neanderthals did, at least 400,000 years ago.) Heat-reddened clay, fire-cracked stone, and fragments of pyrite mark where Neanderthals gathered around a campfire 400,000 years ago in what’s now Suffolk, England. Based on chemical analysis of the sediment at the site, along with the telltale…
