Deep sea worm fights 'poison with poison' to survive high arsenic and sulfide levels

A deep sea worm that inhabits hydrothermal vents survives the high levels of toxic arsenic and sulfide in its environment by combining them in its cells to form a less hazardous mineral. Chaolun Li of the Institute of Oceanology, CAS, China, and colleagues report these findings in a study published in the open-access journal PLOS Biology.
