Arms Use Real Nerves, Electrodes
The Rehabilitation Institute of Chicago introduced Claudia Mitchell, whose new bionic arm allows her to control her arm movements through thought processes alone, without any visible delays.
She was joined by Jesse Sullivan, the world’s first “bionic man,” who received his arm more than a year ago. Mitchell’s arm gives her more natural movement and a greater range of motion than Sullivan’s. Mitchell, 26, lost her arm in a motorcycle accident after she left the Marines in 2004. “Learning to operate this arm has been really exciting,” Mitchell said. “My other arm, previously, it just didn’t work well enough to bother with wearing it. So now it’s exciting to learn how to do things over again.” To provide thought-controlled movement in the bionic arm, nerves located in the amputee’s shoulder, which once went into the amputated arm, are rerouted and connected to healthy muscle in the chest.
Although work that created Sullivan’s arm preceded the research by DARPA, he said he’s proud to test a type of bionic arm that soldiers could someday use.
“We’re excited about collaborating with the military,” said the developer of Sullivan’s arm, Dr. Todd Kuiken, director of neuroengineering at the Center for Artificial Limbs at the Rehabilitation Institute of Chicago, one of 35 partners now in a DARPA project to develop a state-of-the-art arm.
Jesse Sullivan has two prosthetic arms, but he can climb a ladder at his house and roll on a fresh coat of paint. He’s also good with a weed-whacker, bending his elbow and rotating his forearm to guide the machine. He’s even mastered a more sensitive maneuver _ hugging his grandchildren. The motions are coordinated and smooth because his left arm is a bionic device controlled by his brain. He thinks, “Close hand,” and electrical signals sent through surgically re-routed nerves make it happen.
A new breed of oversized rat is popping up in Britain as a result of less-frequent waste collection.
Waste collectors pick up trash just once every two weeks, under a new scheduled intended to help meet government-imposed recycling targets, the Daily Mail reported. The result, scientists say, is an explosion in the rat population. The rats are also getting bigger — up to one foot long — due to a diet rich in processed foods.
“Rats are becoming harder to control,” said Martina Flynn, who has been commissioned by the British Pest Control Association to find new ways of controlling the rats, “because they know food is easy to find and will eat that rather than poisoned bait. They are acquiring a behavioral resistance which means they won’t eat what’s in the bait box.” Flynn said citizens need to be concerned, as the problem could develop into a 21st century plague.
“We need to find ways of dealing with this new breed, because conventional methods seem to be no longer effective,” she said.
The long sought after and much hyped Citago gas station video from 9/11 has finally been released.
Remember that there are another 84 tapes that the FBI is withholding. The gas station had several security cameras aimed in the direction of the pentagon. Flight 77 flew directly over the gas station at an altitude of roughly 50 feet, less than 3 seconds from impact. If this is all the footage from the gas station then why was it retained under national security laws for five years?
