The authors of a paper on brain genetics published online in June in the Proceedings of the National Academy of Sciences (PNAS) are retracting it for “a potential confound relating to statistical inference.”
Here’s the notice for “Identification of gene ontologies linked to prefrontal–hippocampal functional coupling in the human brain:” Continue reading Authors retract PNAS brain genetics paper for statistical issues
A brain imaging study in children with epilepsy has been retracted by the Journal of Magnetic Resonance Imaging due to a statistics error.
Here’s the notice for “Microstructural Brain Abnormalities of Children of Idiopathic Generalized Epilepsy With Generalized Tonic-Clonic Seizure: A Voxel-Based Diffusional Kurtosis Imaging Study”: Continue reading Tonic-clonic stats error sinks epilepsy paper
Want bogus data, million-dollar fraud allegations and a scientist on the lam? We give you Alain Malafosse.
The British Journal of Psychiatry has retracted a June 2013 paper by Malafosse and his colleagues on the genetics of bipolar disorder in children because Malafosse allegedly fabricated key data in the study.
The article, “Childhood maltreatment and methylation of the glucocorticoid receptor gene NR3C1 in bipolar disorder,” purported to find that people with bipolar disorder who had experienced more, and more severe, abuse early in life were more likely to show epigenetic changes. According to the abstract:

Proof that organic chemistry is hard for everyone, not just pre-meds: A paper in the Journal of the American Chemical Society was retracted after the structures of compounds being studied were “misassigned.”
Another study by author Doo Ok Jang, also in JACS, was retracted in 2013 for the same reason; you can read our coverage here. Jang and Sang Yoon Kim published that one in 2008; the paper we’re talking about today was published in 2010 by Jang and Sung Jun Kim.
Here’s the notice for “Indium-Mediated Catalytic Enantioselective Allylation of N-Benzoylhydrazones Using a Protonated Chiral Amine:” Continue reading Structure fumble sinks second of author’s JACS papers
The authors of a Journal of Experimental Medicine have retracted it, blaming the first author for data and figure manipulation.
The paper, “The requirements for natural Th17 cell development are distinct from those of conventional Th17 cells,” was initially published in September 2011 and has been cited 25 times, according to Thomson Scientific’s Web of Knowledge. First author Jiyeon Kim was an MD-PhD candidate at the University of Pennsylvania until this year, according to a LinkedIn profile.
Here’s the notice: Continue reading First author blamed for retraction in prestigious medical journal
Cory Toth is up to nine retractions.
The University of Calgary researcher who told us earlier this year that he “will not be publishing in the world of science in the future” has retracted two papers from Neuroscience.
Here’s the notice for “Local erythropoietin signaling enhances regeneration in peripheral axons:” Continue reading Diabetes researcher Cory Toth now up to nine retractions
Nasser Chegini, an ob-gyn formerly on the faculty at the University of Florida who has been the subject of an Office of Research Integrity (ORI) inquiry for several years, has a second retraction.
Chegini is suspected of having used bogus data in some of his work — research backed in part by some $4 million in federal funding.
The new retraction involves a 2008 paper in Reproductive Sciences on which Chegini was senior author. Here’s the notice: Continue reading Second retraction appears for former University of Florida ob-gyn subject to ORI probe
Always do a careful reading of your galleys, editors.
We imagine readers of Biomedical Chromatography’s special issue, “Reminiscences of Chang Kee Lim,” did some flipping back and forth when they found the same paper published twice.
Here’s the resulting notice for “Determination of 4-hydroxy-2-nonenal in serum by high-performance liquid chromatography with fluorescence detection after pre-column derivatization using 4-(N,N-dimethylaminosulfonyl)-7-hydrazino-2,1,3-benzoxadiazole”: Continue reading Déjà vu: Double pub in the same issue earns a retraction
An article purporting to find that black children are at substantially increased risk for autism after early exposure to the measles-mumps-rubella vaccine has been shelved.
Although we don’t know if the events are related, the move comes amid claims that a CDC whistleblower has accused health officials of suppressing information about the link.
Not surprisingly, the prospect that the CDC has been sitting on evidence of an autism-vaccine connection for more than a decade has inflamed the community of activists wrongly convinced that such a link exists.
The paper, “Measles-mumps-rubella vaccination timing and autism among young african american boys: a reanalysis of CDC data,” was written by Brian Hooker, an engineer-turned-biologist and an active member of that community. It was submitted in April, accepted on August 5, and published on August 8.
Translational Neurodegeneration, which published the article earlier this month, has now removed it and posted the following notice: Continue reading Journal takes down autism-vaccine paper pending investigation
The Indian Society of Periodontology has changed their editorial policy as the result of an author who had “neither taken adequate permission from nor given due acknowledgement to all authors concerned.”
Now, any authors will be required to sign a contract acknowledging accountability for the content of the submitted paper, as well as be able to state the specific work contributed by each author.
Here’s the notice from the Journal of the Indian Society of Periodontology: Continue reading This retraction has teeth: Journal changes publication policy after discovering misconduct
