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.

Where are our petabyte drives? Brian Hayes takes us through the reasons storage is “stuck” in the low terabytes. The tl;dr is that we got such exceptional capacity growth in the late 90s and early 00s we don’t need much more right now, so the focus since then has been on SSDs, networking, interfaces, etc, […]

White hat hackers get paid to find holes in their own employers’ online systems, and plug those holes before they become serious security risks. It’s a job that pays handsomely…mostly because few job candidates, even experienced IT professionals, have the skills to scamper over firewalls and infiltrate the deepest recesses of a battle-tested network. But […]
Why buy one of those expensive and confusing universal remotes, clogged with enough buttons to launch a space shuttle, when you could accomplish the same electronic control right on your favorite mobile device? The Blumoo Universal Remote, now just $52.99 in the Boing Boing Store, harnesses the audio power of all your household equipment right […]
You may not love Microsoft Word, but you’ve definitely used it. Other than being one of the most ubiquitous programs on the planet, it’s been the go-to word processing system for more than a quarter-century because it’s as basic as it gets. But occasionally, you’ve got assignments that beg for a lot more options than simple […]
