Taste researcher falsified data in two papers: ORI

ori-logoA federal report has found that a former University of Maryland postdoc “falsified and/or fabricated” data in two papers about taste receptors.

The Office of Research Integrity report found that Maria C.P. Geraedts manipulated bar graphs in the papers to “produce the desired result.” Both have been retracted. Geraedts left academia in 2014, and is now a science writer.

We reported on one retraction in July, “Gustatory stimuli representing different perceptual qualities elicit distinct patterns of neuropeptide secretion from taste buds,” published in The Journal of Neuroscience.

The other, “Transformation of postingestive glucose responses after deletion of sweet taste receptor subunits or gastric bypass surgery,” published in 2012 in the American Journal of Physiology Endocrinology and Metabolism, was retracted in September. Here’s the note, which cites the university’s investigation: Continue reading Taste researcher falsified data in two papers: ORI

Author with three retractions objects to mega-correction following investigation

DevelopmentWe’ve uncovered a “mega-correction“ for a 2010 paper in Development, posted as the result of an investigation into the first author which has already led to three retractions.

Last year, the Utrecht University investigation into Pankaj Dhonukshe found “manipulation in some form” in four papers, and concluded that he committed a “violation of academic integrity.” The investigation also led to the retraction of a 2012 Cell paper and two papers in Nature that were co-authored by Dhonukshe. 

Development began investigating the corrected paper after being contacted by one of the authors and alerted to the results of the university’s investigation. The notice includes a statement from Dhonukshe objecting to the correction. Continue reading Author with three retractions objects to mega-correction following investigation

Diederik Stapel retraction count updated to 57

stapel_npcWe’ve learned about two more retractions we missed for Diederick Stapel, the Dutch social psychology researcher who has now racked up a total of 57 retractions by our count.

Both retractions were issued after a committee released a report which established fraud in dozens of papers co-authored by Stapel.

Stapel is still #4 on our leaderboard.

Prostate cancer paper flagged by ORI is retracted following PETA prompt

cover_issue_129_en_USA federal investigation into a paper on prostate cancer has now led to a retraction. In an unusual twist, it happened following a request from the animal rights group People for the Ethical Treatment of Animals (PETA).

In January, the Office of Research Integrity reported that corresponding author Dong Xiao “intentionally fabricated data” in an Oncotarget study of how a steroid inhibits the growth of prostate cancer. Xiao, a former cancer researcher at the University of Pittsburgh, claimed that he had tumor data from more mice than he did, and falsified several figures.

In July, after no sign of the retraction, a researcher at PETA followed up with the journal, Oncotarget, on behalf of the organization “and our more than 3 million members and supporters to request the immediate retraction.”

Last month, they received a reply from the publisher, which they forwarded to us:

A retired obstetrics and gynecology professor under federal investigation for misconduct has notched his ninth retraction.

The latest retraction stems from an investigation by the University of Florida, where Nasser Chegini worked until 2012, which found fabricated data in three figures in a paper on the muscle cells that line the uterus.

The paper, “Differential expression of microRNAs in myometrium and leiomyomas and regulation by ovarian steroids,” was published in The Journal of Cellular and Molecular Medicine. It’s been cited 74 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the note:

Authors pull Science paper on molecular wires for “inappropriate data handling”

pic.mag.current-issueThis week’s issue of Science includes a retraction of a highly cited paper about manipulating the current in a string of molecules with a magnet, after an investigation by the co-authors revealed “inappropriate data handling” by the first author.

According to the note, the co-authors’ suspicions arose when they tried to follow-up on the data. Following a “thorough investigation,” they concluded that first author Rabindra N. Mahato had handled the data in such a way that they could no longer trust the conclusions. In the end, Mahato agreed to the retraction.

Here’s more from the note: Continue reading Authors pull Science paper on molecular wires for “inappropriate data handling”

So you want to be a whistleblower? Part III

This is the third and final article in a series by John R. Thomas, Jr., a lawyer at Gentry Locke [Editor’s note, 3/26/19: He has since moved to Haley, Hafemann, Magee and Thomas] who represents whistleblowers in a variety of False Claims Act cases.  His first article discussed the background of the False Claims Act (“FCA”) and how it might apply to scientific misconduct, and his second article provided advice on how to know if you have a viable FCA case. In this installment, he writes about the procedure for bringing an FCA case and how the damages and whistleblower’s share are calculated.

Suppose you are a potential whistleblower. You believe that your PI is manipulating data in publications. You suspect that a fellow lab technician is tampering with experiments. You are a PI who knows that your colleague is “double dipping” on Federal grants. What should you do? Continue reading So you want to be a whistleblower? Part III

Dutch investigation of researcher violated rules of “fair play”: Ombudsman

The National Ombudsman of The Netherlands has criticized some aspects of an investigation by Utrecht University that found a researcher had committed “a violation of academic integrity.”

Specifically, the Ombudsman found the investigation — which we covered last year — did not adequately involve the affected researcher, Pankaj Dhonukshe, and therefore violated rules of “fair play.” Dhonukshe expressed relief in a statement he emailed to us about the ruling: Continue reading Dutch investigation of researcher violated rules of “fair play”: Ombudsman

“Rigging of the peer-review process” kills parasite paper

s13369083k

A paper on nematode parasites appears to have been infected with a nasty strain of a publishing problem known as fake peer review. By our count, the phenomenon has felled approximately 250 papers in total.

The affected review, “The important role of matrix metalloproteinases in nematode parasites,” explores a type of enzyme secreted by the parasite. Published in Helminthologia, it’s been cited once, according to Thomson Scientific’s Web of Knowledge.

Unfortunately, the retraction note doesn’t give us too many details about how the peer review process was manipulated:

Danish neuroscientist sentenced by court for lying about faked experiments

court caseIn a rare development, neuroscientist Milena Penkowa has been sentenced by a Danish court for faking data.

The ruling, from the Copenhagen City Court, resulted from Penkowa’s publication of her 2003 thesis describing experiments that she never carried out. The court “placed weight” on the fact that she didn’t just commit fraud, but “systematically supplied false information” to avoid being caught, according to the court’s notice.

The sentence is nine months of “conditional imprisonment,” according to our translation; The University Post, a newspaper affiliated with the University of Copenhagen, calls it a “nine month suspended sentence with a two years probation.”

Here’s the full summary of the new ruling, from the Copenhagen City Court (translated from Danish by One Hour Translation):
