No Microbes In First Sample From Lake Vostok

So what exactly do they suspect these bacteria have been eating down there in the deep dark cold?

Cthulhu has been feeding them bits of the Snickers bar he was given as campaign contribution... Or perhaps he's been feeding them bits of the campaign contributors themselves.

But seriously, a background of 10 critters / cc isn't all that 'clean' and

Bulat and his colleagues counted the microbes present in the ice sample and checked their genetic makeup to figure out the phylotypes. They counted fewer than 10 microbes/ml ? about the same magnitude they would expect to find in the background in their clean room. And three of the four phylotypes they identified matched contaminants from the drilling oil, with the fourth unknown but also most likely from the lubricant.

points to one of the bigger concerns about this experiment - you are going to contaminate the lake at this point as the drilling technology is pretty primitive - basically pouring hot water into a hole.
