Cells containing DNA have been found deep beneath Antarctica’s ice. But the most important question still needs to be answered…are they still alive? Here’s more from Crux Guest Blogger at Discover:
The search continues for life in subglacial Lake Whillans, 2,600 feet below the surface of the West Antarctic Ice Sheet—but a thrilling preliminary result has detected signs of life. At 6:20am on January 28, four people in sterile white Tyvek suits tended to a winch winding cable onto the drill platform. One person knocked frost off the cable as it emerged from the ice borehole a few feet below. The object of their attention finally rose into sight: a gray plastic vessel, as long as a baseball bat, filled with water from Lake Whillans, half a mile below.
The bottle was hurried into a 40-foot cargo container outfitted as a laboratory on skis. Some of the lake water was squirted into bottles of media in order to grow whatever microbes might inhabit the lake. Those cultures could require weeks to produce results. But one test has already produced an interesting preliminary finding. When lake water was viewed under a microscope, cells were seen: their tiny bodies glowed green in response to DNA-sensitive dye. It was the first evidence of life in an Antarctic subglacial lake…
