The buzz about radioactive wasps at a Cold War-era nuclear site in South Carolina just won’t die. Investigators found “hot” nests inside a nuclear weapons facility in South Carolina, with scientists warning it could be evidence of either a leak or contamination that wasn’t previously detected.

Workers at a site in South Carolina that once made key parts for nuclear bombs in the United States have found a radioactive wasp nest but officials said there is no danger to anyone.

The Department of Energy said radiation contamination levels on the wasps' nest were over 10 times the regulated maximum.
