No Microbes In First Sample From Lake Vostok 60

The very uppermost layer of Lake Vostock appears to be 'lifeless' so far, says Bulat, but that doesn't mean the rest of it is. 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."

    They're expecting to get more microbes from the sediment at the bottom of the lake. Sediments are comparatively stuffed with nutrients, and the lack of light and cold aren't much of a problem (there is probably stuff growing [jamstec.go.jp] at the bottom of the Mariana Trench, just very slowly).

There are never any bugs you haven't found yet.
