Lake Vostok disappointed scientists

In a mysterious ice pond in Antarctica has not yet been found of life. The famous Lake Vostok in Antarctica, alas, disappointed scientists. According to Sergei Bulat, an employee of St. Petersburg Institute of Nuclear Physics and Team Leader from the lake of ice samples, they could not detect traces of life. Photos from open sources About preliminary analysis results reported on October 18 by Nature magazine, citing Bulat. By his According to him, the upper layers of the lake are apparently “lifeless.” Scientist added that these are “very preliminary results” so far, except in addition, there is hope to detect microorganisms in deeper layers. Damask steel was very cautious in evaluations mainly because he and his colleagues studied ice frozen on drilling equipment. It, figuratively speaking, only “plunged” into the mysterious lake. So far, it has not been possible to obtain full-fledged water samples from the East. “Four types of bacteria have been found which are related to contaminants (contaminating microorganisms). Same bacteria were found in drilling fluid, and lake water from the drill was washed this dirty drilling fluid, two more kinds of bacteria from the samples were found on a person. That is nothing interesting. General the conclusion is: there are no cells at the top (in the snow cover), in the lake ice also has no cell populations – it is lifeless there. Water can contain something, “Izvestia quoted Bulat as saying. Bulat added that now he is counting on new designs to be delivered to to his laboratory in May next year – if everything goes well well. Recall that Lake Vostok was discovered in 1996 on the basis of forecast made by famous geographer Andrei Kapitsa back in late fifties. Attempts to get to the lake undertaken repeatedly, but for various reasons postponed. Only in February of this year, the Russian expedition managed to reach its surface. In 2013, it is planned to extract new water samples from lakes, and in the season 2013-2014. should start already full blown exploration of the lake itself with instruments. In the world of science, Lake Vostok arouses increased interest because it is for millions years was isolated from the outside world by a thickness of ice. As a result in microorganisms not similar to other forms could have survived life on earth. The conditions in Lake Vostok, in addition, resemble those that exist outside of our planet, for example, on moons of Jupiter. Therefore, exploring the lake may also be useful. and for space biology.
