ST. PETERSBURG, Russia, Jan. 28 (UPI) -- Russian scientists drilling into the Antarctic's Lake Vostok, 13,000 feet beneath the continent's ice sheet, say they are in a race against the weather.
With the Antarctic summer almost over, temperatures will soon drop and the scientists will have to depart by Feb. 6 while conditions are still mild enough for a plane to land at the remote Vostok base, the BBC reported Friday.
