Battery life wouldn't be an issue for drones if they could just recharge on power lines as needed. That's exactly what an experimental new quadcopter can now do, allowing it to stay aloft pretty much indefinitely.

Danish scientists have developed an origami snake robot that could one day search for survivors at disaster sites, or even explore other planets. The device moves via rectilinear locomotion, just like real snakes often do.

Scientists have developed a fluorescent material they claim can more reliably detect explosives in the vicinity, by being a bit more selective about when it changes color.
