Cell runs a lengthy correction, rather than retraction, for image problems

The journal Cell has an interesting — and somewhat puzzling — correction this month that we’ll add to our “mega-correction” file. At issue is a paper, published in October, from the lab of Harvard’s Stephen Elledge, a noted genetics researcher, whose first author is a post-doc there named Michael Emanuele. According to the notice, Emanuele (singled … Continue reading Cell runs a lengthy correction, rather than retraction, for image problems

A mega-correction, but no retraction, in the Journal of Cell Science

In our 2011 year-end post, we promised to keep …an eye on what may be an emerging trend: The mega-correction. We’ve seen errata notices that correct so many different errors, it’s hard to believe the paper shouldn’t have been retracted. It’s unclear what this means yet, but watch this space for coverage of more examples. … Continue reading A mega-correction, but no retraction, in the Journal of Cell Science

Cell retraction for bogus images in genetics paper reveals another, in Journal of Molecular Biology

Call it bad luck, but the journal Cell has been victimized again by image manipulation. For the second time this month, the publication has retracted a paper whose authors acknowledged that one of them had played around with the figures. Published in August 2009, the paper, “Population-Level Transcription Cycles Derive from Stochastic Timing of Single-Cell … Continue reading Cell retraction for bogus images in genetics paper reveals another, in Journal of Molecular Biology
