Florida leadership researcher Walumbwa notches sixth retraction

jorgbehavIn February we reported on the case of Fred Walumbwa, a leadership scholar at Florida International University who was poised to lose five papers in the Leadership Quarterly for reasons not entirely clear but which appeared to involve problems with the data.

Now we see a sixth retraction for Walumbwa, this one in the Journal of Organizational Behavior. The article, titled (ironically enough), “Authentically leading groups: The mediating role of collective psychological capital and trust,” had appeared in September 2009. Per the abstract:

University of Maryland researchers notch second retraction

jbc 42514Two researchers at the University of Maryland who retracted a paper earlier this year for a duplicated figure have withdrawn another, this time for unknown reasons.

The Journal of Biological Chemistry (JBC) paper has been cited 16 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice, for “Hsp90 Interaction with INrf2(Keap1) Mediates Stress-induced Nrf2 Activation,” which is unfortunately a return to the JBC’s opacity: Continue reading University of Maryland researchers notch second retraction

Ethics training paper retracted because data couldn’t be shared

sci eng ethicsA group of authors at the University of Oklahoma have retracted a 2013 paper on ethics training after the university found that the data they used couldn’t be shared publicly.

Here’s the notice for “Improving Case-Based Ethics Training: How Modeling Behaviors and Forecasting Influence Effectiveness:” Continue reading Ethics training paper retracted because data couldn’t be shared

Former Mount Sinai postdoc faked gene therapy data: ORI

ori logoA former postdoc at the Mount Sinai School of Medicine in New York faked data in four published papers, one submitted manuscript, and four NIH grant applications, according to new findings by the Office of Research Integrity.

We reported on six retractions from Savio Woo’s Mount Sinai lab in 2010, from the Proceedings of the National Academy of Sciences (PNAS), the Journal of the National Cancer Institute, and two each from Human Gene Therapy and Molecular Therapy. The PNAS paper, as we noted then:

claimed to have discovered a possible cure for phenylketonuria, or PKU, in mice—a finding that was cited more than 30 times and trumpeted in the media.

At the time, Mount Sinai said that two of the lab’s postdocs had been dismissed for misconduct. Now, more than three and a half years later, the ORI reports that a former postdoc in that lab, Li Chen: Continue reading Former Mount Sinai postdoc faked gene therapy data: ORI

Retractions appear in case of former Kansas water scientist rebuked for misconduct

groundwaterBack in December, the University of Kansas issued a public censure of a former water researcher who, the school says, engaged in a pattern of plagiarism and other shoddy publishing practices.

Marios Sophocleous, who’d held the position of senior scientist at the Kansas Geological Survey:

Scientist found to have falsified data in thesis sues to keep her PhD

org lettersIn August 2012, the authors of “Novel Approach to the Lundurine Alkaloids: Synthesis of the Tetracyclic Core,” a paper in Organic Letters, retracted it:

The authors retract this Organic Letters communication on the basis that the RCM of 24 to give 25 (Scheme 6) is not reproducible; thus, the reduction of 25 to give 26 (Scheme 7) is also not reproducible.

The case was covered in some detail by The Heterocyclist blog, and also by Derek Lowe at In The Pipeline, who called it “an odd retraction.” Lowe recently picked up the story with an update: The first author, Suvi Orr, is suing the University of Texas-Austin, where she earned her PhD and did the work, to stop them from taking away her degree.

The Austin American-Statesman reported last month: Continue reading Scientist found to have falsified data in thesis sues to keep her PhD

Brutal honesty: Author takes to PubPeer to announce retraction — and tells us she’ll lose PhD, professorship

Over the past week, there have been a number of comments on PubPeer — a site of which we’re big fans — about a 2007 paper in Oncogene.

The comments suggested that the figures in the paper had problems. Some bands seemed to be duplicated, and one of the images looked very much like that of another paper.

Then, today, first author Eriko Suzuki left this comment: Continue reading Brutal honesty: Author takes to PubPeer to announce retraction — and tells us she’ll lose PhD, professorship

Authors retract study suggesting magnesium prevents Alzheimer’s in mice

NIH/Harvard team loses aging study to manipulated data

agecoverAge has retracted a 2012 article by a group of scientists from the National Institutes of Health and Brigham and Women’s Hospital in Boston after an NIH inquiry turned up evidence of data manipulation in the work.

The article, “Aging decreases rate of docosahexaenoic acid synthesis-secretion from circulating unesterified α-linolenic acid by rat liver,” came from the lab of Stanley Rapoport, chief of the brain physiology and metabolism section of the National Institute on Aging.

As the abstract explained: Continue reading NIH/Harvard team loses aging study to manipulated data

Fraud fells Alzheimer’s “made to order” neurons paper in Cell

cell414In 2011, a group of researchers at Columbia University reported in Cell that they had been able to convert skin cells from patients with Alzheimer’s disease into functioning neurons — a finding that raised the exciting prospect of “made to order” brain cells for patients with the degenerative disease. As one researcher not involved with the study, led by Asa Abeliovich, put it:

“[This is] simply a remarkable and complete piece of work which will now set a standard for stem cell work in neurological disease. The standard of the characterization of the neuronal cultures is very high,” John Hardy at University College London, U.K., wrote to [Alzforum]. He was not involved in the work but is taking a similar approach in his own lab.

According to the abstract of “Directed Conversion of Alzheimer’s Disease Patient Skin Fibroblasts into Functional Neurons:”
