A former employee in the public health division of the Oregon Health Authority committed misconduct in 56 case reports about Clostridium difficile infections in Klamath County, Oregon, as well as in a manuscript submitted to JAMA Internal Medicine and a published report in the Morbidity and Mortality Weekly Report in March, 2012.
Ryan Asherin, previously a Surveillance Officer and Principal Investigator at the OHA, was a busy man. According to the details from a report by the U.S. Office of Research Integrity, Asherin:
Following revelations of data issues and other problems (which crashed our server last week), Science is retracting a paper claiming that short conversations could change people’s minds on same-sex marriage.
In what can only be described as a remarkable and swift series of events, one of the authors of a much-ballyhooed Science paper claiming that short conversations could change people’s minds on same-sex marriage is retracting it following revelations that the data were faked by his co-author.
[3:45 p.m. Eastern, 5/28/15: Please see an update on this story; the study has been retracted.]
Donald Green, of Columbia, and Michael LaCour, a graduate student at UCLA, published the paper, “When contact changes minds: An experiment on transmission of support for gay equality,” in December 2014. The study received widespread media attention, including from This American Life, The New York Times, The Wall Street Journal, The Washington Post, The Los Angeles Times, Science Friday, Vox, and HuffingtonPost, as LaCour’s site notes.
David Broockman and Joshua Kalla, graduate students at University of California, Berkeley, were two of the people impressed with the work, so they planned an extension of it, as they explain in a timeline posted online yesterday: Read the rest of this entry »
The suit, originally filed in February in the U.S. District Court of Southern Ohio by Mitch Potterf, owner of a Columbus, Ohio CrossFit, alleges that a 2013 paper by OSU’s Steven Devor and colleagues falsely reported that nine subjects had dropped out of the study because of “overuse or injury.” The study, we should note, concluded that CrossFit is a useful form of exercise. It has been cited twice, according to Thomson Scientific’s Web of Knowledge.

The authors of a study on the effects of the hormone leptin on the liver have retracted it from Cell Metabolism, almost four months after the Office of Research Integrity (ORI) determined it contained faked data, courtesy of its first author.
However, the authors say that the paper’s conclusions remain valid, and are supported by new experiments and additional research by outside groups.
A group of chemists whose work was investigated by the University of Texas-Austin has had another paper retracted, this one of a Chemical Science study previously subjected to an Expression of Concern.
That makes six retractions for Christopher Bielawski and Kelly Wiggins.
Both retractions appeared in Biochemical and Biophysical Research Communications, one in October 2014 and one in January 2015. His story began two decades ago in 1994, when he published a paper in Nature that couldn’t be reproduced, and was eventually retracted in 2013.
The best part of the story, of course, is that when his university was attempting to recreate his experiments, Bezouška broke into a lab fridge to tamper with the experiments. Unbeknownst to him, he was caught on hidden camera. Read the rest of this entry »
A 2002 paper has been retracted by Cancer after some of the authors notified the journal that they hadn’t agreed to submit it — and an investigation found that a number of the patients described had been made up.
Here’s the notice for “Radioimmunotherapy of small-volume disease of metastatic colorectal cancer: results of a phase II trial with the iodine-131–labeled humanized anti–carcinoembryonic antigen antibody hMN-14:” Read the rest of this entry »
The paper tries to explain how Epstein-Barr virus blocks the immune system’s attempts to destroy it. According to the notice, the three “nonexperimentalist authors” – identified in the paper as two P.I.’s from University of Texas at Austin and one from the University of California, San Francisco – didn’t know the figures “were not reflective of original Northern blot and immunoblot data.”
That leaves UT Austin PhD student Jennifer Cox under the bus. Her LinkedIn says she pursued a PhD from 2010-2015, though it’s unclear if she’s received a degree. Cox’s name is at the top of P.I. Christopher Sullivan’s list of past lab members, and she’s the only one on the page whose name doesn’t hyperlink to additional information, such as a contact.
The world, it seems, cannot get enough of Sokal-type hoaxes.
A French journal, Sociétés, has retracted an article allegedly penned by one Jean-Marc Tremblay but actually written by two sociologists, Manuel Quinon and Arnaud Saint-Martin, who spoofed the work of the journal’s editor, Michel Maffesoli.
