Exterior scientists concluded that it’s an arsenic-tolerant extremophile, however not a profoundly totally different life type.
Retraction
However now, in 2025, it’s as soon as once more spurring controversy; on Thursday, Science introduced that it’s retracting the research.
Some critics, corresponding to Redfield, cheered the transfer. Others questioned the timing, noting that 15 years had handed, however just a few months had passed by since The New York Occasions printed a profile of Wolfe-Simon, who’s now returning to science after being perceived as a pariah.

Particularly, Vinson and Thorp referenced the criticism that the bacterium’s genetic materials was not correctly purified of background arsenic earlier than it was analyzed. Whereas emphasizing that there was no suggestion of fraud or misconduct on the a part of the authors, they wrote that “Science believes that the important thing conclusion of the paper relies on flawed knowledge,” and it ought to due to this fact be retracted.
Jonathan Eisen, an evolutionary biologist on the College of California, Davis, criticized the transfer. Talking with Science’s information staff, which is impartial from the journal’s research-publishing arm, Eisen stated that regardless of being a critic of the 2010 paper, he thought the dialogue of controversial research ought to play out within the scientific literature and never depend on subjective selections by editors.
In an eLetter hooked up to the retraction discover, the authors dispute the retraction, too, saying, “Whereas our work might have been written and mentioned extra rigorously, we stand by the info as reported. These knowledge had been peer-reviewed, overtly debated within the literature, and stimulated productive analysis.”

If that had been the case, “you’d must retract half the literature.”
