Life in Lake Vostok? Nyet
Russan explorers drilled through kilometers of ice to a huge lake of liquid water beneath Antarctica, known as Lake Vostok. They hit the lake's surface in February, though pressure under the ice caused a 40m column of water - which, of course, immediately froze - in the borehole. So they augured out the ice and brought it to the surface. Evidence of ancient microscopic life? Disappointingly, the word so far is no. There are plans to sample other areas and greater depths.
