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.
The Journal of the American Chemical Society (JACS) has retracted three articles that had earned expressions of concern by chemistry researchers who were under investigation at the University of Texas, Austin.
The newly retracted articles have each been cited more than 50 times, according to Thomson Scientific’s Web of Knowledge.
The three papers are: Read the rest of this entry »
The American Heart Association’s journal Circulation has issued an expression of concern for a paper about the molecular underpinnings of arrhythmias that was co-authored by a biomedical engineer who committed fraud on a massive scale.
According to an investigation by the Office of Research Integrity (ORI), former Vanderbilt engineer Igor Dzhura faked nearly 70 images and drastically over-estimated the number of experiments he conducted. He was banned from receiving federal funding for three years.
The fraud has resulted in six retracted papers, Dzhura has agreed to retract six papers, which have been cited more than 500 times. [Ed. note: at this time, only one paper has actually been retracted]
Two more retractions have popped up for Nasser Chegini, the former University of Florida professor currently under investigation by the Office of Research Integrity (ORI).
Both retractions appear in the Journal of Clinical Endocrinology & Metabolism. The notices indicate that an investigation report from the University of Florida “found substantial data misrepresentation” in two JCEM articles about Smads, signaling molecules that carry messages from TGF-beta receptors to the nucleus.
Here’s the notice for “The Expression of Smads in Human Endometrium and Regulation and Induction in Endometrial Epithelial and Stromal Cells by Transforming Growth Factor-Beta” ( ):
The authors of a 2011 Science paper that proposed a new way to direct chemical bonds have withdrawn the paper after concerns about the data prompted an investigation and Editorial Expression of Concern last year from the journal. The retraction is the second for the group, which has also had seven other expressions of concern.
After a reader emailed the editors to raise suspicions about the data, corresponding author Christopher W. Bielawski, then based at the University of Texas at Austin, led an investigation of all the figures. It found substantial problems: “In over 50% of the figure parts, the authors deemed the data unreliable due to uncertainty regarding the origin of data or the manner in which the data were processed,” according to the retraction notice.
UT Austin concluded that there had been misconduct, but did not elaborate.
A new paper in the MDPI journal Publications reports that the only controlled study on the effect of giving COPD patients Omega-3 has been cited 52 times since being retracted. Of those, only two mentioned the retraction.
In 2005, Chest published an article that found that COPD patients who took omega-3 supplements for 2 years experienced improvements in their condition, such as better walking tests and a decrease in sputum cytokines. But when an institutional investigation found the lead author had falsified the data, the journal retracted the paper in 2008.
That’s news to many researchers in the field. Among the 50 papers that cited the research after 2008 without stating it had been retracted, 20 included “specific data” from the paper, while the other 30 “cited the reference in passing.” Articles citing the retracted study have themselves been cited 947 times total, pointing to the ripple effect this kind of unwitting mention can have throughout the literature.
A former dental researcher at the University of Maryland, Baltimore, has lost a 2009 paper in the journal Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontology for fabricating his data on an NIH-funded study.
The researcher, Mark A. Scheper, is not identified in the retraction notice as the person implicated in the university investigation. However, one of his co-authors confirmed his involvement. Scheper died in January 2014 at age 45 of natural causes, according to the Maryland State Medical Examiner.
The article was titled “The oncogenic effects of constitutive Stat3 signaling in salivary gland cancer cells are mediated by survivin and modulated by the NSAID sulindac.” It appeared online in March 2009, and has been cited six times, according to Thomson Scientific’s Web of Knowledge.

The paper tells Retraction Watch that the undergraduate, Rico Johnson, has been removed from the staff of the paper.
It took five months, but in December a second retraction popped up for disgraced accounting professor James H. Hunton.
Hunton resigned his teaching post at Bentley University in December of 2012. An extensive investigation by Bentley showed that not only was the data in two papers falsified. Hunton also lied about non-existent confidentiality agreements and tried to destroy evidence of his lies by unsuccessfully wiping his laptop and changing metadata on files.
The first paper Hunton was accused of faking, ironically about accounting fraud, was retracted in 2012.
