Apparently being zapped by a zillion DNA-mutating, radioactive particles from a nuclear power source isn't all bad. National Geographic reports that two major nuclear accident areas โ€” the bomb-testing area around the Bikini Atoll and the regions around the Chernobyl meltdown โ€” are starting to bounce back. The biosphere can survive nuclear radiation, apparently. According to Environmental Graffiti, "Edward Calabrese, a professor at the University of Massachusetts at Amherst, claims that radiation may fall into a concept called hormesis: poisons that are lethal at high doses, are beneficial in low ones." Or, as another scientist put it, the life forms that don't die from radiation just grow stronger. [Environmental Graffiti]
