It sounds like something from the movies, but it's true: Researchers unearth an organism frozen inside a glacier, take it back to the lab and discover it's still alive. In this case it's a plant called a bryophyte, a moss that survives being frozen in a glacier in the dark for some 400 years. Wow.

An asteroid nine times the size of a cruise ship is dropping by Earth on Friday, and it's not coming alone. Asteroid 1998 QE2 will be about 3.6 million miles from our planet at its closest approach. And its proximity has already given scientists a surprise: It has its own moon, measured at about 2,000 feet wide.
