There’s a record for the World’s toughest bacterium!

Introducing: D. Radiodurans better known as Connan the Bacterium. It withstands attacks from acid baths, extreme temperatures, and even radiation doses. It was found living on cow patties and elephant dung and came to scientists’ attention when it refused to die in food sterilization tests. 

Connan is looking to be our ticket into Mars; as it beats most of the survival constraints like vacuum, dormancy, oxidative damage, etc. It is also predicted to be used in creating more portable medicine for astronauts. 

The bacterium’s genetic code as the unique ability to repeat itself so many times that damage in one area can be recognized and quickly repaired. Needless to say, this seems like the Superman of microscopic organisms.
