Otto Bock's mind-controlled bionic arms
let Austria's Christian Kandlbauer work, play and even drive, but it seems the latter passion may have lead to the 22-year-old's untimely demise. Two days after a road accident where the young man's specially-modified Subaru crashed into a tree, Kandlbauer was pronounced brain-dead and taken off life support late last week. It's not known whether the prosthetic arms themselves had anything to do with the crash -- one was found ripped from his body at the scene -- but both he and his vehicle were cleared to drive by local authorities after passing a number of tests. Honestly, it's a tragedy for science and humanity either way.
