Conan the Bacterium

An anonymous reader writes "The world's toughest organism, able to withstand thousands of time more radiation than a human, is reported by the Weizmann Institute to have its secret to survival as a tightly packed DNA ring. Their Science article indicates that radiation-induced breakages are held tightly packed rather than floating off into the intracellular fluid. The bacteria,Deinococcus radiodurans, was discovered decades ago in canned food that was sterilized using radiation. Red patches appeared in the cans - colonies of the bacterium - setting off questions as to how it could have survived."

Out of curiosity, I checked with the OED Online and here's what it has to say:

b. Pl. viruses. An infectious organism that is usu. submicroscopic, can multiply only inside certain living host cells (in many cases causing disease) and is now understood to be a non-cellular structure lacking any intrinsic metabolism and usually comprising a DNA or RNA core inside a protein coat

So, I guess it's "viruses" after all.
