DVICE: Water jetpack may be man's greatest invention to date
Video of a jetpack powered by water. On the downside, you're tethered to the ground by the hose providing the water. On the positive side, when the jets cut out, you just fall right back into the water. Looks like a fun way to fly!
A wirelessly-controlled micro-gripper has been videotaped grasping living cells as a demonstration of what it is capable of. Only now working in a laboratory situation, they hope to eventually have a device available for use in minimally-invasive surgery. The developers caution that a great deal of work still needs to be done so practical implementation is years down the road.
