Another busy week at Retraction Watch. Here’s what was happening elsewhere: Continue reading Weekend reads: Nature’s torrent of retractions, peer review’s Golden Rule
Authors retract PNAS brain genetics paper for statistical issues
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
White House takes notice of reproducibility in science, and wants your opinion
The White House’s Office of Science and Technology Policy (OSTP) is taking a look at innovation and scientific research, and issues of reproducibility have made it onto its radar.
Here’s the description of the project from the Federal Register: Continue reading White House takes notice of reproducibility in science, and wants your opinion
Tonic-clonic stats error sinks epilepsy paper
A brain imaging study in children with epilepsy has been retracted by the Journal of Magnetic Resonance Imaging due to a statistics error.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
Retraction appears for psychiatrist sought for arrest in alleged fraud scheme
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:

Structure fumble sinks second of author’s JACS papers
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that organic chemistry is hard for everyone, not just pre-meds: A paper in the Journal of the American Chemical Society was retracted after the structures of compounds being studied were “misassigned.”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.

First author blamed for retraction in prestigious medical journal
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
Authors ask Science to retract Hayabusa asteroid paper
The Japan Aerospace Exploration Agency (JAXA) has requested that Science retract a 2006 paper about the makeup of asteroid Itokawa as observed from the spacecraft Hayabusa, the news section of Science reports.
Instead of calibrating their equipment on Earth, the scientists assumed they’d see both magnesium and silicon in the x-ray spectra, and used that assumption to assess the rest of the chemical composition of the asteroid.
The paper may be based on faulty assumptions, but the conclusions have been backed up by other published papers, according to the Science magazine report: Continue reading Authors ask Science to retract Hayabusa asteroid paper
PubPeer Selections: Boosting memory in Science, extending lifespan in Nature, quantum anesthesia in PNAS
As Retraction Watch readers probably know, we’re big fans of PubPeer, the post-publication peer review site that allows comments on papers. Discussions there have led to a number of corrections and retractions, and even more importantly, authors are starting to respond to clarify results, acknowledge errors, or otherwise advance knowledge. After all, as we often note, there’s a long way between raising questions about a study and retracting it.
With all of that in mind, we’re pleased to launch a new weekly post that will be called “PubPeer Selections” in which we’ll highlight featured discussions on PubPeer. Here’s the first installment: Continue reading PubPeer Selections: Boosting memory in Science, extending lifespan in Nature, quantum anesthesia in PNAS
Diabetes researcher Cory Toth now up to nine retractions
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
