The lake has been reached, the water tested, and some "micro-organisms" found.
very primitive, but nothing amazing.

While very entertaining, this article is just a lot of "Blavatski"..

The lake has been reached, the water tested, and some "micro-organisms" found. very primitive, but nothing amazing.

Perhaps you are confused by the liklihood that the lower portions of the coring consisted of ice that had once been lake water.
