As part of research on how to make better prosthetic legs, Vanderbilt University engineers put people on a treadmill and made them stumble. Over and over. By better understanding peoples’ stumble reflex, they hope to improve the computer-controlled stumble response in prosthetics. But to learn how people catch themselves, they had to trip them first. […]
When it comes to large computer systems, not one of them is fully secure. Even with constant updates to the platforms that keep vital networks humming, there’s always a back door. And companies are willing to pay handsomely to effective bouncers that can keep an eye on them. Call them ethical hackers or white hat […]
