The weirdest headline popped up in my feeds today: Russian scientist says he is stronger and healthier after injecting himself with 'eternal life' bacteria. That got my attention.\n\nAnatoli Brouchkov, head of the Geocryology Department at Moscow State University, found a bacteria in the permafrost that is 3.5 million years old. They call it Bacillus F. How it is dated to that age is not mentioned in the paper. They suggest that the bacteria themselves are 3.5 million years old, but it appears they are extremophiles that live in permafrost that dates to 3.5 million years. As always in the paper, important details are lacking.
