Scientists Melt Million-year-old Ice In Search Of Ancient Microbes

From Sciencedaily.com

Researchers from the University of Delaware and the University of California at Riverside have thawed ice estimated to be at least a million years old from above Lake Vostok, an ancient lake that lies hidden more than two miles beneath the frozen surface of Antarctica. The scientists will now examine the eons-old water for microorganisms, and try to figure out how they survived the ages in total darkness, in freezing cold and without food and energy from the sun. segments of ice were cut from an 11,866-foot ice core, 656 feet above the surface of Lake Vostok. This ice was once water in lake Vostok itself and froze to the bottom of the existing Antarctic ice sheet. No samples have been taken directly from lake Vostok as of yet due to fears of contaminating the area. Since the lake has not had direct contact with the surface world for at least 15 million years, this would be a contamination of one of the most pristine environments on Earth.
