Now, back to the world's most extreme life forms...
I'm Bob Karson with "The Discovery Files" -- new advances in science and engineering from the National Science Foundation.
Extremophiles. Not a new reality show, but they are real, and they are extreme. They're organisms able to survive in very hostile environments. In barren, desolate places previously thought to be devoid of life, like the recently discovered microbes found living in a solid rock glacier.
Thirty miles outside of Boulder, Colorado, high in the Rockies, researchers have discovered evidence of life where it's not supposed to be. Microbes -- thriving deep within the frozen rock layers -- metabolizing nitrogen to live.
Similar life forms have been uncovered in Antarctica, in the boiling water of undersea vents, and even in the bricks of ancient Peruvian pyramids.
By unlocking the secrets of life in extreme places on earth, we can better understand the possibilities of life on less hospitable worlds in space.
