For the first time, Russia will abandon its base at Vostok in Antarctica because of a lack of fuel and supplies for the coming winter.
Vostok, the most isolated manned research outpost on Earth, was established in 1957. The base sits atop a giant ice-covered lake first identified in the 1970s.
It is officially the coldest place on Earth, with a recorded low of minus 89.2 Celsius.
...and scientists suspect the lake itself, cut off from the biosphere for millennia, may contain unusual lifeforms.
