Artificial muscles lift 80 times their weight
 

Other than a few models from Boston Dynamics, most robots don't exactly leave us quaking in fear. That might be off the table soon, though, thanks to a breakthrough from researchers at the National University of Singapore (NUS). They've developed polymer-derived artificial muscles that can stretch out up to five times in length, enabling them to lift 80 times their weight. That could one day result in life-like robots with "superhuman strength and ability," which could also run on very little power, according to the team. They expect to have a robotic limb that could smack down any human in arm-wrestling within five years -- putting a possible cyborg version of Over The Top alarmingly within reach.
