Touch system provides 'an iPad on every wall'

A new touch-activated system projects onto walls and other surfaces and can recognize hand posture and gestures to identify individual users.

New system warns of impending solar flares

Researchers believe they've found a way of predicting solar flares more than a day before they occur, possibly helping to protect satellites, power grids and astronauts from dangerous radiation.

Another vote for sorghum for biofuel

It's hard to know whether sorghum is getting increasing attention as a possible biofuel source because it makes sense as a solution to our energy and environment challenges, or mostly because it could boost Midwest farm economies.

API glitch may explain fast-draining phone batteries

Almost a quarter of apps that contain Android's explicit power control APIs, or wakelocks, may have major battery-draining bugs.
