A paper in the journal Genomics that was retracted last March has now been "un-retracted," reports Retraction Watch. As Adam Marcus recounts in his post, the article submitted to Genomics listed Nicola Solomon as its first author. But when the study's PI Sally Camper was making the changes reviewers had asked for, she noticed problems with some experiments done by Solomon, who had by then left the lab. The experiments were re-done, and since the paper was returned without Solomon's contributions, she was moved to the acknowledgements section. That authorship change resulted in the original retraction.
Solomon has since been the subject of an Office of Research Integrity investigation, which found she did not do some of the DNA sequencing that she'd claimed to have done.
Marcus reports that the journal will be issuing a notice saying that the concern over the authorship changes "appears to have been non-problematic," and that the retraction has been rescinded.
