Neurons and Deinococcus Radiodurans

Very speculative science from LiveScience: what can be done with greater understanding of a regenerating microbe that shares some attributes in common with your cells? "This is the first case, I think, of a living cell that clinically dies - its DNA is chopped into little pieces and it has no metabolism - when desiccated, and yet, as long as it can reconstitute its genome, it reconstitutes its own life ... Radman believes his team's findings open up the possibility of resurrecting dead cells in our own bodies, specifically those in our brains. ... It allows us now, legitimately, to dream of bringing back to life dead or close to dead neurons. ... Like Deinococcus, neurons carry two - albeit slightly different - copies of their genomes: one from Mom and the other from Dad. In fact, all the cells in our bodies except sperm and egg contain two genome copies. Therefore, it's possible that one day scientists could resurrect dead neurons using repair mechanisms similar to those employed by Deinococcus, Radman said."
