First author blamed for retraction in prestigious medical journal

jemcoverThe 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.

Authors ask Science to retract Hayabusa asteroid paper

jaxa_logoThe 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

pubpeerAs 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

neuroscienceCory 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.

Chegini, via University of Florida

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

Déjà vu: Double pub in the same issue earns a retraction

biomedchromAlways 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

Journal takes down autism-vaccine paper pending investigation

translational neurodegenerationAn 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

This retraction has teeth: Journal changes publication policy after discovering misconduct

Screen Shot 2014-08-26 at 10.43.29 AMThe 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

Language of a liar named Stapel: Can word choice be used to identify scientific fraud?

stapel_npcA pair of Cornell researchers have analyzed the works of fraudster Diederik Stapel and found linguistic tics that stand out in his fabricated articles.

David Markowitz and Jeffrey Hancock looked at 49 of the Dutch social psychologist’s papers — 24 of which included falsified data. (Stapel has lost 54 papers so far.)

According to the abstract for the article, “Linguistic Traces of a Scientific Fraud: The Case of Diederik Stapel,” which appeared in PLoS ONE: Continue reading Language of a liar named Stapel: Can word choice be used to identify scientific fraud?
