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 Both have been retracted.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or gastric bypass surgery,” published in 2012 in the American Journal of Physiology Endocrinology and Metabolism, was retracted in September.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

Bone researcher manipulated data in JAMA study, says investigation

Screen Shot 2015-10-27 at 10.53.53 AMA bone researcher manipulated data in a 2011 JAMA study about an inexpensive treatment for osteoporosis. That’s the conclusion of an investigation at the researcher’s former workplace, the Women’s College Hospital in Toronto, the Toronto Star reports.

The study — led and manipulated by Sophie Jamal — followed 243 women over two years, as they applied nitroglycerin ointment once a day. The ointment is currently used to prevent chest pain and treat anal fissure pain by relaxing blood vessels; Jamal’s study concluded it could help patients with osteoporosis, too:

Among postmenopausal women, nitroglycerin ointment modestly increased [bone mineral density] and decreased bone resorption.

But even the modest effect was too good to be true. Continue reading Bone researcher manipulated data in JAMA study, says 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:

Boldt’s retraction count upped to 94, co-author takes legal action to prevent 95th

Screen Shot 2015-09-16 at 12.12.13 AM

We’ve found two recent retractions and an expression of concern for Joachim Boldt, former prominent anesthesiologist and currently Retraction Watch leaderboard’s 2nd place titleholder. He now has 94 retractions.

One of the retracted articles contains falsified data, along with a researcher who didn’t agree to be a co-author, according to an investigation by the Justus Liebig University Giessen, where Boldt used to work. The expression of concern is regarding some questionable data. The other new retraction is actually one of 88 papers that a group of editors agreed to retract back in 2011, after they were “unable to verify” approval by the Institutional Review Board (IRB) for the studies.

One of those 88 papers, we’ve discovered, has still has not been retracted. According to an editor at the journal, they haven’t removed it because one of Boldt’s co-authors has threatened them with legal action. Continue reading Boldt’s retraction count upped to 94, co-author takes legal action to prevent 95th

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”

There’s “no evidence” research was conducted at all in retracted cancer paper

cov200h (1)To one reader of a paper on a nerve cancer, the researchers, based at a hospital in China, seemed to have found a very large number of cases of a rare cancer to study. That observation triggered an investigation into the paper that led to its retraction — and the concern that the authors in the paper never did the research at all.

The authors say they recruited 156 patients who had a particular kind of cancer that affects the tissue around nerves, known as malignant peripheral nerve sheath tumors. For context on how rare that is: Other researchers found a mere 1,182 new cases over a nearly four-decade period in the U.S. The study, according to the methods section of the paper, was supposedly done with patients who had a specific type of the disease, and who were

consecutively recruited from Wuhan Union Hospital, Huazhong University of Science and Technology in Wuhan (Hubei, China) between July 2000 and November 2012

According to the retraction note for “Common genetic variants in the microRNA biogenesis pathway are associated with malignant peripheral nerve sheath tumor risk in a Chinese population,” the hospital where the work was done never treated all of those patients:

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):

4th ORI-flagged paper by Oregon student is retracted

home_cover (2)The last of four papers containing data falsified by University of Oregon neuroscience student David Anderson has been retracted.

When the Office of Research Integrity report flagging the papers came out in July, Anderson told us he “made an error in judgment,” and took “full responsibility” for the misconduct.

The newly retracted paper, “A common discrete resource for visual working memory and visual search,” published in Psychological Science, has been cited 28 times, according to Thomson Scientific’s Web of Knowledge. According to the abstract, it demonstrates a possible link between working memory and the ability to “rapidly identify targets hidden among distractors.”

But according to the retraction note, Anderson produced “results that conformed to predictions” by “removing outlier values and replacing outliers with mean values”  in some of the data.

Here’s the retraction note in full:
