Nature Stands by Stem Cell Paper

Following up on an anonymous accusation of faked images in a stem cell paper it published last year, the journal Nature released a statement today saying it has investigated the claims and hasn't found any problems with the paper in question.

"The image has been evaluated by professionals and we are satisfied they are original and not unduly manipulated," the journal said in a note e-mailed to reporters. "While we wouldn't encourage anonymous accusations, least of all those broadcast indiscriminately, there have been occasions where anonymous whistle-blowing has revealed fraudulent papers, so we will at least consider such accusations."
