Former Columbia postdoc faked Alzheimer’s research in Cell and Nature

with 7 comments

cover_natureRyousuke Fujita, a former Columbia University postdoc who admitted to having faked the findings of a 2011 Cell paper in a retraction notice last year, also faked the results of a 2013 Nature paper, according to a new report from the Office of Research Integrity (ORI).

But the story began falling apart when the Cell retraction said that he “acknowledged inappropriately manipulating image panels and data points, as well as misrepresenting the number of repeats performed.”
