"MATERIALS: Rocket propels prosthetic arm"

Developers at Vanderbilt University are perfecting a rocket-powered prosthetic arm that promises to give amputees a fast, powerful, responsive substitute for a missing limb by 2009. The experimental arm and hand, complete with articulated fingers and opposable thumb, uses an adapted liquid rocket fuel and could provide the best option yet for limb replacement, according to its creators. The bionic arm is one of three projects under way to create a good-as-original prosthetic limbs under the Defense Advanced Research Projects Agency's Revolutionizing Prosthetics program.
