Have you guys ever heard about this bacteria?Deinococcus radiodurans is a bacteria that can live through blasts of radiation thousands of times greater than the level that would kill a human being. Radiation is measured in units called rads. A dose of 500 to 1,000 rads is enough to kill a person. D. radiodurans thrives even after being hit by up to 1,500,000 rads.The bacterium’s Latin name means "strange berry that withstands radiation." Still, scientists aren’t entirely clear exactly how and why D. radiodurans is so much more radiation-resistant than other microbes. After all, other microbes have many of the same tools, although not in as high numbers and variety as D. radiodurans does. And some other bacteria have more than one copy of their genes, although none have quite as many copies as D. radiodurans. Scientists are sifting through the genes of D. radiodurans, trying to figure out if the bacterium has any unique tools or genes that give it extra radiation protection. May be we can find a solution for the hole in Ozone.I think that this bacteria must have lived in the upper layers of earth and should have evolved to be radiation resistant.But the toughest question to be answered is how they resist all these radiations.Any ideas?
