Techniques for monitoring rainfall with signals from mobile phone networks are making their way to small-scale farmers in rural Africa

Ignition First in a Fusion Reaction

Device Acts as Both Solar Cell and Battery. A new photoelectric device can convert light into charge that it can then store indefinitely.

A new theory proposes a wearable, reversible fabric that would emit close to zero radiation from one side while emitting a large amount from the other, potentially keeping a person warm when worn one way and cool when flipped inside out.
