Heat makes water evaporate. Now it appears light can, too
In the lab, shining light on water made it evaporate faster. This never-before-seen effect, if real, might be happening naturally all around us.
Come explore with us!

A new device exploits the contrast between bright spots and shade to produce a current that can power small electronics.
Scientists at the Georgia Institute of Technology built a 'smart' surface on which to play table tennis. It can track the location, speed and direction of the ball.
Researchers have mimicked the first stages of planet formation in the lab. All they needed were glass beads and a catapult.
The word quantum often gets misused. What does it mean? Think small. Really, really small.
A teen researcher from Georgia has developed a light that could replace reflectors on bike wheels. Flexing tires provide all the power it needs.
High-speed video shows how the combined motions of a shoe’s swinging and landing on the ground provoke shoelaces to come untied.
Three scientists probe how the natural world makes light, in hopes of using this information to design new and better products.
Two young scientists have developed ways to tap into wind power on a small scale.
Science and engineering careers explore all aspects of wind, from terrible tornadoes to aeronautics and clean energy.
