Ancient germs

From New Scientist:

WITH a hibernation period of up to 100 million years, bacteria discovered on the Arctic sea floor may have longest life cycle of any known organism.

Casey Hubert from the Geosciences Group at Newcastle University, UK, and colleagues came across the bacteria while studying biological activity in sediment samples from the sea floor off the Norwegian island of Svalbard.

There might be another explanation for what he found, but I like this one.
