Underground Fukushima Microbes Survive in Biofilm Shields, Challenging Decommissioning

Researchers studying water beneath Fukushima’s reactors found bacteria thriving in radioactive conditions not thanks to classic radiation resistance but likely because protective biofilms form on metal surfaces; some microbes can cause metal corrosion, complicating cleanup efforts, and scientists speculate marine bacteria may have ridden in with the 2011 tsunami, revealing unexpected life in extreme environments.
