MaryBethP writes "Scientists in Italy announced Wednesday that Pierpaolo Petruzziello, a 26-year-old Italian who had lost his left forearm in a car accident, was successfully linked to an artificial limb that was controlled by electrodes implanted in his arm and connected to the median and ulnar nerves. He has learned to control the artificial limb with his mind. According to CNet, Petruzziello says he could feel sensations in it, as if the lost arm had grown back again. The BBC has a brief video showing the arm in operation."
