Residents of Birmingham, Alabama woke last Friday to skies that looked more like an ocean, with a series of huge "wave" shaped crests rolling slowly across the sky. Experts have now explained the phenomenon as perfect examples of "Kelvin-Helmholtz" waves, when a fast layer moves over a slower layer and drags the top along creating a curled shape.
Future X-Factor and American Idol stars can rest easy in the knowledge scientists have been working tirelessly to take out the guesswork in what makes a hit song. They've developed a software program that can predict chart positions with about 60% accuracy.
If you've ever been hospitalized and sent home to recover, you know it can be overwhelming. Now imagine it from a child's point of view.

If they reach their destinations in Japan and Australia, they could set the world record for the longest distance traveled by an unmanned vehicle.
