In a surprising discovery, scientists have found evidence of a tundra landscape in Greenland that's millions of years old.

How did it happen? How'd the zebra get its stripes?
In Rudyard Kipling's version, a gray, horsey-looking beast went into "a great forest 'sclusively full of trees and bushes and stripy, speckly, patchy-batchy shadows," stayed there awhile, and after a "long time"... got stripy.
In the early 1990s, a young brain researcher named Ivan Soltesz heard a story that would shape his career.
His adviser told him about a school for children whose epileptic seizures were so severe and frequent that they had to wear helmets to prevent head injuries. The only exception to the helmet rule was for students who received an award.

Whatever hobby you have, keep at it. A little study published this week suggests that having a creative outlet outside the office might help people perform better at work.
Psychologists from San Francisco State University found that the more people engaged in their hobbies, the more likely they were to come up with creative solutions to problems on the job. And no matter what the hobby was, these people were also more likely to go out of their way to help co-workers.
