Lake Vostok disappointed scientists


In the mysterious body of water-ice in Antarctica have not found life. The famous Lake Vostok in Antarctica, unfortunately, disappointed scientists. As Sergey Bulat, a member of the St. Petersburg Institute of Nuclear Physics and head of the study group of extracted samples of ice from the lake, they could not find traces of life.

Preliminary test results reported Oct. 18 in the journal Nature, citing Bulat. According to him, the upper layers of the lake, seems to be "lifeless". The scientist added that it is still "very preliminary results," in addition, there is hope to find microorganisms in the deeper layers. Bulat was very cautious in estimates, mainly because he and his colleagues have studied the ice on the frozen drilling equipment. It is, so to speak, only the "plunged" into a mysterious lake. Full of water samples from the East until could be obtained.

"Were found four kinds of bacteria which are contaminants (contaminant microorganisms). These bacteria were also found in the drilling fluid and drill with lake water was obmyta this dirty drilling fluid, two further samples of bacterial species have been found in humans. That is nothing interesting. general conclusion is: the top (in snow) cells not in the lake ice is also no cell populations — there lifeless. water may contain something "- quoted by Bulat" Izvestia ". Bulat added that he was now looking forward to new models have to be paid to him in the lab in May next year — if all goes well.

Recall Lake Vostok was discovered in 1996 on the basis of the forecast, which was well-known geographer Andrei Kapitsa in the late fifties. Attempts to reach the lake have been many times, but for different reasons postponed. Only in February of this year the Russian expedition managed to reach the surface. In 2013, plans to produce new models of water from the lake, and in the 2013-2014 season. should begin full-scale study of the lake devices.

In the world of science Lake Vostok is an increasing interest because it has for millions of years has been isolated from the outside layer of ice. As a result, it could be preserved organisms, not like the other forms of life on Earth. Conditions in Lake Vostok, also resemble those that exist outside of our planet, for example, the satellites of Jupiter. Therefore, the study of the lake can be useful also for space biology.
