   Fifteen years after publishing an explosive but   
   long-criticized paper claiming to describe a   
   microbe that could substitute arsenic for   
   phosphate in its chemical makeup, Science is   
   retracting the article, citing “expanded”   
   criteria for retraction.   
      
   The authors stand by their findings and disagree   
   with the retraction, and contend the decision   
   doesn’t reflect best practices for publishers.   
      
   Many scientists, including David Sanders, a   
   biologist at Purdue University in Lafayette, Ind.   
   who has previously argued for the paper’s   
   retraction in posts for Retraction Watch, believe   
   the paper’s results were simply the result of   
   contamination of the authors’ materials. He told   
   us he was “glad” to see the retraction.   
      
   “The problem was not that later research   
   undermined the conclusions,” Sanders said. “The   
   problem was that the evidence presented in the   
   article was not supportive of the conclusions   
   from the start and that all the results were   
   based on the fact that the arsenate was   
   contaminated with phosphate.”   
      
   While the retraction notice does not explicitly   
   state the contamination concern as a reason for   
   the retraction, a blog post by the journal’s   
   editors does.
