Readers of ThingsAreGood know that bacteria can make dangerous heavy metals a lot less dangerous. Now scientists have found out how the bacteria can eat away at uranium with no harm done to it.

“Assembling a battery of evidence, scientists have for the first time placed the bacterial enzymes responsible for converting uranium to uraninite at the scene of the slime, or “extracellular polymeric substance” (EPS), according to a study led by the DOE’s Pacific Northwest National Laboratory in today’s advance online edition of PLoS Biology.”
Even after reading the article I’m still confused about how this actually works.
