Monkeys outfitted with neural implants have learned to control temporarily paralyzed muscles in their arms. So instead of controlling a robot arm with its mind, the monkey controls its own muscles that have become "disconnected" from its brain. The research, conducted by the University of Washington and the Washington National Primate Research Center, is a step forward in the development of technology that routes around a damaged spine, enabling a patient to once again manipulate paralyzed body parts. From IEEE Spectrum:
In exchange for a reward of applesauce, the monkeys had been conditioned to create just the right amount of torque in their wrists to move a cursor on a display so that it hit a target. To conduct the experiments, the researchers used anesthesia to block signals in a nerve just below the shoulder of a monkey’s arm, temporarily paralyzing the rest of the limb. The brain cells that control wrist movement were still firing in response to the monkey’s desire to hit the target and get the payoff, but with the neural connection shut down, the wrist remained limp. The scientists implanted electrodes into the monkey’s motor cortex and fed the electrical signals they received from the monkey’s brain into a computer. The computer then translated the signals into a stimulating current that was fed to electrodes implanted below the nerve block in the monkey’s wrist. The monkeys were able to learn to manipulate their own brains to get their wrists moving.
Neglected public payphones in New York City are being turned into “GuyFi” stations: a place where one can rub one out for the sake of “stress relief.” Annalee Newitz reports on the wank booths from a company named “Hot Octopus”… The company reported that at least 100 men used the booth on its opening day […]
You’d be forgiven for thinking the videocassette format long-dead, but it turns out that Betamax is still around. Sony is finally going to withdraw tapes from sale, bringing a 40-year story to an end. The last recorders were sold in 2002. ベータビデオカセットおよびマイクロMVカセットテープ出荷終了のお知らせ [Sony; via The Verge]
A leaked Comcast memo discloses that the company’s consumer data caps have nothing to do with network congestion, contrary to its public claims. The internet service provider has often complained (such as when lobbying against net neutrality) that it must impose limits on service to prevent network congestion. The argument suggests that these measures are […]
Remember back to the time when people thought java was just a hip way to talk about coffee? Or you vaguely remembered from geography class that it’s an island in the South Pacific? We’ve come a long way since then and now that we’ve rocket blasted into the tech future, you’re going to need to […]
Plastic is so 2013. You don’t want to buy something only to throw it away or lose it and barely care. You like nice things and want to hang onto them. The Plazmatic lighter here is a high quality, high tech alternative to the typical cheap, plastic lighter you get at the old gas station. […]
Real engineers build things. Super cool engineers build things with their hands and fingers, like our engineering forefathers did. No idea where to even begin to do that? This step by step Arduino course is now 92% off and is going to get you up and running, from zero to hero, in no time. So […]
