JBC cancer paper felled by duplication is one author’s second retraction this month

A 2002 paper in the Journal of Biological Chemistry on how lung cancer cells resist death has been retracted for duplicating figures from a 2001 paper. The retracted paper, “Fibroblast growth factor-2 induces translational regulation of Bcl-XL and Bcl-2 via a MEK-dependent pathway: correlation with resistance to etoposide-induced apoptosis,” shares the first and last authors … Continue reading JBC cancer paper felled by duplication is one author’s second retraction this month

Lost your data? Blame an earthquake

A natural disaster is to blame for a retraction about lethal brain tumors. At least, that’s where the authors say the problem started: with a 2010 earthquake that caused a loss of “substantial data.” The paper, “Superoxide-dependent uptake of vitamin C in human glioma cells,” looks at how the cells of lethal brain tumors interact … Continue reading Lost your data?

“Significant concerns” and formal investigation unwind Nature Nanotech sequencing paper

Following “significant concerns” raised by outside researchers and a formal university investigation, a group of authors in Taiwan has retracted a Nature Nanotechnology paper on DNA sequencing after they “could not reproduce the results of the work,” or even provide “a complete set of raw data for the original experiments.” The paper, “DNA sequencing using electrical conductance measurements … Continue reading “Significant concerns” and formal investigation unwind Nature Nanotech sequencing paper

Exosome pioneer’s paper retracted after investigation finds “multiple” faked figures

The Journal of Immunology is retracting a 2006 article about the role of exosomes in pregnancy at the behest of the University of Louisville in Kentucky, following a misconduct investigation that “determined multiple figures” in the paper were falsified. First author Douglas Taylor is a pioneer in exosome biology, having discovered the release of exosomes from tumor … Continue reading Exosome pioneer’s paper retracted after investigation finds “multiple” faked figures

Cell Press investigating possible image manipulation in influential yeast genetics paper

Cell Press is looking into anonymous allegations that a pair of influential papers on gene activation in yeast may contain more than two dozen instances of image manipulation, according to a spokesperson for the journal. The accusations first appeared in March on PubPeer, where they triggered a small avalanche of comments, including one asserting “unambiguous … Continue reading Cell Press investigating possible image manipulation in influential yeast genetics paper

Harvard biofilm paper in Cell breaks down after challenged findings can’t be repeated

Researchers at Harvard have retracted a Cell paper on biofilm disassembly after they repeated the experiment—following contradictory results from another team—and the new results “can no longer support” the original conclusions. The 2012 paper, “A Self-Produced Trigger for Biofilm Disassembly that Targets Exopolysaccharide,” describes a factor called norspermidine, produced by the bacteria Bacillus subtilis, that appeared to break … Continue reading Harvard biofilm paper in Cell breaks down after challenged findings can’t be repeated

Third retraction for GWU biologist as university seeks to dismiss his $8 million lawsuit

Cancer biologist Rakesh Kumar has chalked up another retraction, this time for “identical,” “duplicated,” and “replicated” figures and images. It comes on the heels of a flurry of motions in Kumar’s $8 million lawsuit against his employer, George Washington University, for breach of contract and emotional distress because it removed him as department chair last year and … Continue reading Third retraction for GWU biologist as university seeks to dismiss his $8 million lawsuit

Former postdoc suing lab head for publishing paper he says he wrote, without his name

A pharmaceutical researcher is suing his postdoctoral advisor and former business partner, accusing him of publishing a paper in PLoS Biology they wrote together, and removing him as an author. According to the complaint, Andrew Mallon and John Marshall co-founded a company, Ardane Therapeutic, to commercialize a potential therapy that Mallon discovered for Angelman Sydrome, a … Continue reading Former postdoc suing lab head for publishing paper he says he wrote, without his name

Gynecologic cancer researcher earns eighth retraction

Noriyuki Takai, a gynecologic cancer researcher in Japan, has notched one more retraction — bringing the total to eight — due to figures that were “processed inappropriately” and did “not accurately report the original data.” According to the notice, Takai alone put the figures together in the 2006 Oncology paper, which tested a histone deacetylase … Continue reading Gynecologic cancer researcher earns eighth retraction

Investigations into Voinnet’s work announced; critic publishes original peer review

The story about Olivier Voinnet, a high-profile plant biologist whose work has fallen under scrutiny, continues to build momentum. Late last week, Voinnet’s employer and one of his funders announced they were investigating his work, and one of the peer reviewers of a soon-to-be-retracted paper has made her original report public. Here’s the statement from … Continue reading Investigations into Voinnet’s work announced; critic publishes original peer review
