For the first time, monkeys have successfully fed themselves with a robotic arm jacked directly into their brains. Neuro-control of robots isn't new, but apparently performing tasks as complicated as eating is a huge challenge. Conducted at the University of Pittsburgh, the demo was captured on video that's now on YouTube. Of course, the research itself may not sit well with people who are against all animal testing. From New Scientist:
Most people who become paralysed or lose limbs retain the mental dexterity to perform physical actions. And by tapping into a region of the brain responsible for movement – the motor cortex – researchers can decode a person's intentions and translate them into action with a prosthetic.
This had been done mostly with monkeys and in virtual worlds or with simple movements, such as reaching out a hand. But two years ago, an American team hacked into the brain of a patient with no control over his arms to direct a computer cursor and a simple robotic arm.
Schwarz's team extracted even more complicated information from the brains of two rhesus macaques by reading the electrical pulses of about 100 brain cells. Normally, millions of neurons fire when we lift an arm or grab a snack, but the signals from a handful of cells are enough to capture the basics, (neurological engineer Andrew) Schwarz says.

Alex Wood is an addict but won’t give up his smartphone. But he has five strategies for limiting its control over him: “I used to wake up tired. My body would ache and my head felt sore, like waking up with a hangover. Finally, I took control, like attending an AA class for addicts, I […]
We just got the Sport model of the EPIKGO hoverboard at my office. Besides being terribly chic, it’s apparently bulletproof.
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
