Russian scientists discovered a frozen woolly mammoth in an icy tomb off the coast of Siberia. Approximately 10,000 years old, the creature was so well-preserved that some of its blood and muscle tissue was intact. That means that just like in Steven Spielberg's blockbuster movie "Jurassic Park," scientists could theoretically bring the woolly mammoth back from extinction using live DNA found in the blood. Critics say just because we can clone a new woolly mammoth doesn't mean we should.

A rare glimpse into life under the sea was captured by a camera thought to be gone forever. A surfer had attached a tiny waterproof camera to his board, only to have a big wave knock it off. But two and a half months later, a fisherman hauled in the algae-covered camera, which was still in working order. While the camera was still recording, it bumped around a coral reef - even capturing a few fish - before coming to rest on the ocean floor. Unfortunately, there was no sign of the Little Mermaid.
