Bionic Arm Provides Hope for Iraq War Amputees

Researchers are collaborating — and the U.S. government is funding — an initiative to bring bionic arms to soldiers who return from the Middle East missing their limbs. Already, a Tennessee man is fitted with the experimental arm which is controlled by his thoughts. He thinks, ‘close hand,’ and electrical signals are sent through surgically re-routed nerves to make it happen. The arm is holding up well under real-world testing, but repairs were needed after the man pulled too hard on a lawn mower. (AP at CNN)
