writes "Using BrainGate, the world's most advanced brain-computer interface, a woman with quadriplegia has used a mind-controlled robot arm to serve herself coffee — an act she hasn't been able to perform for 15 years. BrainGate, which is being developed by a team of American neuroscientists from Brown and Stanford universities, and is currently undergoing clinical trial, requires a computer chip to be implanted in the motor cortex of the patient, which it then transmits to a computer for processing. Like all brain-computer interfaces, the user must train the software — but once this is done, you simply think of a movement, and the software moves the robot accordingly. Moving forward, the researchers would like to miniaturize the system and make it wireless — at the moment, BrainGate users have a box attached to their head, and they're tethered to a computer — which is OK for robot arm use at home, but obviously doesn't grant much mobility. The work was partly funded by DARPA, with the hope of creating more advanced prosthetics for wounded war veterans."

An anonymous reader writes "In the midst of Congressional races around the country, one stands out to techies. Thomas Massie, an MIT whiz kid who pioneered touch-based interfaces and founded SensAble Technologies in the 1990s, is the favorite to win the Republican nomination in his Kentucky district next week. SensAble was recently sold on the cheap, but in a new exclusive, Massie explains why he left the haptics firm years ago to lead a simpler life of farming, family, and guns — lots of guns. Along the way he built a solar-powered, off-the-grid house and became a local hero of the Tea Party. Now Massie is leading the charge to get more engineers into politics, and if he wins, he could be a force to be reckoned with in Washington, DC."Read Replies (0)

parallel_prankster writes "Older adults who drank coffee — caffeinated or decaffeinated — had a lower risk of death [full paper is paywalled, at the New England Journal of Medicine] overall than others who did not drink coffee, according to a study by researchers from the National Cancer Institute (NCI), part of the National Institutes of Health, and AARP. Coffee drinkers were less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections, although the association was not seen for cancer. These results from a large study of older adults were observed after adjustment for the effects of other risk factors on mortality, such as smoking and alcohol consumption. They also found that the association between coffee and reduction in risk of death increased with the amount of coffee consumed. Relative to men and women who did not drink coffee, those who consumed three or more cups of coffee per day had approximately a 10 percent lower risk of death. Researchers caution, however, that they can't be sure whether these associations mean that drinking coffee actually makes people live longer."Read Replies (0)
