After 15 years of debate, a study that announced the alleged discovery of an arsenic-eating microbe has been retracted by the journal Science due to contaminated and flawed data. However, the original study authors disagree with the move.
The microbe strain, labeled GFAJ-1, was recovered from the salty water of arsenic-rich Mono Lake in California by a research team led by Felisa Wolfe-Simon of NASA's Astrobiology Institute.
