    Antarctic test of novel ice drill poised to begin

    Any day now, a team of 40 scientists and support personnel expects to begin using a warm, high pressure jet of water to bore a 30 centimeter hole through 83 meters of ice. Once it breaks through to the sea below, they’ll have a few days to quickly sample life from water before the hole begins freezing up again. It's just a test. But if all goes well, in a few weeks the team will move 700 miles and bore an even deeper hole to sample for freshwater life that may have been living for eons outside even indirect contact with Earth’s atmosphere.
