Researcher who called plagiarism “the worst type of fraud” retracts paper for…plagiarism

with 32 comments

arq brasAs a reporter on the police beat many years ago, one of us (Adam) used to hang out with a press officer whose desk at the station had the following sign: “Uma boca fechado não recolhe nenhum pé.”

At least, that’s what it would have been had we been in Rio. In Palmer Park, Maryland, the sign read: “A Closed Mouth Gathers No Foot.”

Journal withdraws diabetes paper written by apparently bogus authors

with 26 comments

BBRCTalk about a Trojan Horse.

Biochemical and Biophysical Research Communications has withdrawn a paper it published earlier this year on metabolic proteins linked to diabetes, not because the article was bogus but because the authors appear to have been. The work itself is accurate — indeed, it likely belongs to a Harvard scientist, Bruce Spiegelman, who’d presented his data on the subject several times recently and was in the process of preparing his results for publication. We’ve written about researchers trying to punk journals with faked articles, and about a researcher who apparently made up a co-author, but here’s something new!

Nature has the story. According to Nature, in July Spiegelman: Read the rest of this entry »

Here’s the retraction notice:
