“The first author assumes all responsibility:” Malaria vaccine article retracted for image manipulation

InfectAndImmunAuthors of a 2012 article in Infection and Immunity investigating a malaria vaccine strategy are retracting it because it “contains several images that do not accurately reflect the experimental data.”

The paper, “Fine Specificity of Plasmodium vivax Duffy Binding Protein Binding Engagement of the Duffy Antigen on Human Erythrocytes,” has been cited 9 times, according to Thomson Scientific’s Web of Knowledge.

The retraction notice places the blame for the image shenanigans squarely on the first author, Asim Siddiqui, who is currently listed on LinkedIn as a faculty member at the College of Applied Medicine at King Saud University in Saudi Arabia.

Here’s the notice: Continue reading “The first author assumes all responsibility:” Malaria vaccine article retracted for image manipulation

Author retracts study of changing minds on same-sex marriage after colleague admits data were faked

science coverIn 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[3:45 p.m. Eastern, 5/28/15: Please see an update on this story; the study has been retracted.]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: Continue reading Author retracts study of changing minds on same-sex marriage after colleague admits data were faked

Highly cited paper on women and heart disease retracted for failure to replicate

ORI-sanctioned former UT-Southwestern cancer researchers up to 10 retractions

CLThere’s been a 10th retraction from two former postdocs at a UT-Southwestern cancer research center who were sanctioned by the Office of Research Integrity (ORI) last September, in part due to observations and comments from Retraction Watch readers.

It’s a 2008 Cancer Letters paper, “Methylation of apoptosis related genes in the pathogenesis and prognosis of prostate cancer,” retracted at the request of Makoto Suzuki, the first author who has claimed responsibility for falsifying data in this and five other papers.

Retraction-plagued management researcher hit with expression of concern

OrgBehav_ak13The editor-in-chief of Organizational Behavior and Human Decision Processes has issued an Expression of Concern about a 2011 paper that explores the link between ethical leadership and employee performance.

The paper, “Linking ethical leadership to employee performance: The roles of leader–member exchange, self-efficacy, and organizational identification,” is one of seven that were flagged in a report by Arizona State University (ASU) that investigated the corresponding author, Frederick Walumbwa, for possible research misconduct, as we noted in November.

“The fit statistics reported in the article contain many errors,” the notice says. It goes on to say that “it is difficult to understand the implications of these errors unless the raw data is made available” — but that the authors were not able to provide it. Here’s the full text of the expression of concern: Continue reading Retraction-plagued management researcher hit with expression of concern

Harvard biofilm paper in Cell breaks down after challenged findings can’t be repeated

CELL_161_4.inddResearchers at Harvard have retracted a Cell paper on biofilm disassembly after they repeated the experiment—following contradictory results from another team—and the new results “can no longer support” the original conclusions.

The 2012 paper, “A Self-Produced Trigger for Biofilm Disassembly that Targets Exopolysaccharide,” describes a factor called norspermidine, produced by the bacteria Bacillus subtilis, that appeared to break down biofilms. The researchers used it to prevent biofilm formation of B. subtilis, Escherichia coli, and Staphylococcus aureus. The paper was cited 72 times, according to Thomson Scientific’s Web of Knowledge.

Two years after it was published, a team from University of Texas Southwestern Medical Center in Dallas and the University of Dundee in the UK contradicted the findings in another Cell publication, “Norspermidine Is Not a Self-Produced Trigger for Biofilm Disassembly.” This time, the authors concluded that norspermidine is not present in B. subtilis biofilms, and actually promotes, rather than breaks down, biofilms. They wrote: Continue reading Harvard biofilm paper in Cell breaks down after challenged findings can’t be repeated

“[W]e can learn from these bad actors:” Trail of retractions follows former Vanderbilt researcher’s fraud

JPhysiol_ak15Authors have retracted three papers from the Journal of Physiology because they contained “falsified or fabricated data.”

The papers, which address calcium signaling in heart muscle cells, are among the six pegged for retraction after an Office of Research Integrity (ORI) investigation into one of the authors, Igor Dzhura, formerly of Vanderbilt University. The ORI found that Dzhura had committed an enormous amount of fraud, involving dozens of faked images and more.

Dzhura was fired from a job at Novartis in November after the company discovered that his application had included the fraudulent work.

The three retracted Journal of Physiology papers and their citation figures, courtesy of Thomson Scientific’s Web of Knowledge, are: Continue reading “[W]e can learn from these bad actors:” Trail of retractions follows former Vanderbilt researcher’s fraud

Déjà vu: JBC epigenetics paper is retracted, then largely re-published with fewer authors

JBCA group of authors have withdrawn a 2011 Journal of Biological Chemistry paper, but then appear to have re-published almost the same paper a month later, only this time with just five of the original nine authors.

The paper, “HDAC3-dependent reversible lysine acetylation of cardiac myosin heavy chain isoforms modulates their enzymatic and motor activity,” concerns a type of protein regulation important to cardiac stress. Written by researchers at the University of Chicago and the University of Pittsburgh, it has been cited 16 times, according to Thomson Scientific’s Web of Knowledge. It was rated “Exceptional” by a reviewer on the Faculty of 1000 website.

As we’ve come to expect from the JBC, here’s the full retraction notice, in all its inexplicit glory: Continue reading Déjà vu: JBC epigenetics paper is retracted, then largely re-published with fewer authors

Third retraction for GWU biologist as university seeks to dismiss his $8 million lawsuit

Cancer biologist Rakesh Kumar has chalked up another retraction, this time for “identical,” “duplicated,” and “replicated” figures and images.

It comes on the heels of a flurry of motions in Kumar’s $8 million lawsuit against his employer, George Washington University, for breach of contract and emotional distress because it removed him as department chair last year and placed his research on hold. Kumar remains employed by the university.

The retracted paper, published in Development in 2004, “Metastasis-associated protein 1 deregulation causes inappropriate mammary gland development and tumorigenesis,” analyzed the role of a protein, MTA1, in mammary gland development and cancer. It was published while Kumar was at M.D. Anderson in Houston, and has been cited 81 times, according to Thomson Scientific’s Web of Knowledge.

By our count, Kumar now has three retractions and five corrections. Numerous anonymous comments on Kumar’s papers have been posted on PubPeer, many of them critiquing images. Here’s the complete notice from Development: Continue reading Third retraction for GWU biologist as university seeks to dismiss his $8 million lawsuit

PNAS paper on dengue virus pulled due to contamination

PNAS_ak11smThe authors of a paper on dengue virus vaccine design published last year in PNAS are retracting it after discovering that their experimental dengue virus was contaminated.

Although they are confident that the strategy is sound, the authors write in their commendably detailed retraction notice that the “inadvertent error” rendered the results “uninterpretable.”

Here’s the retraction notice: Continue reading PNAS paper on dengue virus pulled due to contamination
