The Famous lake Vostok in Antarctica has disappointed scientists

 

In the mysterious subglacial water in Antarctica have not yet found life. The famous lake Vostok in Antarctica, alas, disappointed scientists. As reported Sergey Bulat, a researcher of St. Petersburg Institute of nuclear physics and head of the research group extracted from samples of lake ice, they could not find traces of life.

Preliminary test results reported on 18 October, the journal Nature citing Bulat. According to him, the upper layers of the lake, apparently, «lifeless». The scientist added that it is «very preliminary results», in addition, there is a hope to detect microorganisms in the deeper layers.

Bulat was very careful in the estimates, mainly because he and his colleagues studied ice, frozen on drilling equipment. It is, figuratively speaking, only «plunged» in the mysterious lake. Full samples of water from the East so far failed to obtain.

«Were found four types of bacteria that belong to contaminants (contaminant microorganisms). The same bacteria were found in the drilling fluid and lake water with borax was washed this dirty drilling fluid, two species of bacteria of the samples were found on the man. That is nothing interesting.

The General conclusion is: at the top (in snow) cells not in the lake ice also no cell populations — there lifelessly. Water can contain», — quote Bulat «news». Bulat added that he now counts on new models, which have come to him in the lab in may next year — if all goes well.

We will remind, the lake Vostok was discovered in 1996 on the basis of the forecast, which was known to the geographer Andrey Kapitsa in the late fifties. Attempts to reach the lake were numerous, but for various reasons was delayed.

Only in February of this year the Russian expedition managed to reach the surface. In 2013 it is planned to produce new samples of water from the lake, and in the season 2013-2014 is to start a full-scale study of the lake devices.

In the world of science lake Vostok is keen interest because it for millions of years was isolated from the outside world the ice. As a result it could be micro-organisms, unlike other forms of life on Earth. Conditions in lake Vostok, in addition, reminiscent of those that exist beyond our planet, e.g. Jupiter’s satellites. Therefore, the study lakes can be useful also for space biology.
