“We would now catch” this conflict of interest: Hindawi journal retracts two papers

A computer science journal has retracted two papers, after discovering “a conflict of interest between the handling editor and one of the authors.”

Matt Hodgkinson, head of research integrity at Hindawi Limited, which publishes the journal Scientific World Journal, told us that the conflict of interest stemmed from the fact that Zheng Xu, an author on both papers, and Xiangfeng Luo, the handling editor on the papers, were “frequent collaborators.”

Xu—who is based at The Third Research Institute of Ministry of Public Security in Shanghai—and Luo—a professor in the School of Computer Engineering and Science at Shanghai University—have co-authored dozens of papers together, including several that were cited in the now-retracted articles. Luo also told us that Xu was his former PhD student.

When Hindawi approached Xu about the conflict of interest, Xu told us he “fully agreed” to retract the articles but claimed there was another reason for the retraction involving a special issue in the journal. More on that in a moment. Continue reading “We would now catch” this conflict of interest: Hindawi journal retracts two papers

Authors retract Science paper after investigation reveals manipulated images

Researchers at a prominent Japanese university have retracted a 2015 paper in Science, after an investigation uncovered image falsification and fabrication.

Last September, the University of Tokyo began an investigation of seven papers from the lab of cell biologist Yoshinori Watanabe after receiving anonymous allegations. In May 2017, the university determined that five papers contained falsified or fabricated images, and announced the results of its investigation on August 1. Two of the papers were published in Science, two in Nature and one in EMBO Reports.

On July 1 2017, EMBO Reports issued an erratum to the 2011 paper flagged in the investigation, correcting issues in several figures. Here’s the retraction notice for “The inner centromere–shugoshin network prevents chromosomal instability,” the 2015 paper in Science and the first of the papers to be retracted: Continue reading Authors retract Science paper after investigation reveals manipulated images

Amid legal battle, psych journal issuing caution about torture paper

A psychology journal plans to issue an editor’s note about a controversial paper exploring what the author called “the biggest scandal to hit” the American Psychological Association (APA) in years.

The note cautions readers that the subject of the paper, published in the SAGE journal Teaching of Psychology, is part of a pending lawsuit, and that “teachers considering using the article in their classrooms” should watch for developments in the case.   Continue reading Amid legal battle, psych journal issuing caution about torture paper

Journal flags four papers by researcher in Spain over figure issues noted on PubPeer

A journal has issued expression of concerns (EOCs) for four papers after a concerned reader notified the editors of issues in several figures.

According to the EOCs, the Journal of Cell Science (JCS) discussed the concerns with the corresponding author, José Ignacio Rodriguez-Crespo, and subsequently notified his institution, Complutense University of Madrid. Last year, all four papers were questioned on PubPeer (1, 2, 3, 4).

The journal’s executive editor, Sharon Ahmad, told us: Continue reading Journal flags four papers by researcher in Spain over figure issues noted on PubPeer

“It was an honest mistake:” Author retracts and replaces chemistry paper 15 years later

In 2001, Chris Orvig was happy when his team had synthesized a molecule with potential therapeutic applications. He and his colleagues published their findings in a 2002 paper in Inorganic Chemistry.

Over a decade later, Orvig discovered a pivotal error in the paper: The authors had misidentified the compound.

Orvig, a professor of chemistry at the University of British Columbia in Vancouver, told us: Continue reading “It was an honest mistake:” Author retracts and replaces chemistry paper 15 years later

When is a citation not enough?

Last year, Boris Ratnikov was reading a paper and saw a familiar image.

He quickly realized: The image was from a 2012 paper he’d written, but wasn’t cited. The 2016 Cell Metabolism paper he was reading had copied a figure from his 2012 PLOS ONE paper without referencing it. 

In September 2016, Ratnikov, who is based at Sanford-Burnham-Prebys Medical Discovery Institute, in La Jolla, California, emailed an editor at Cell Metabolism to express his concern about the duplication and omitted citation.  

Although the journal told us it “carefully investigated Dr Ratnikov’s concerns,” the editors ultimately did not think the literature needs correcting.

Does failing to cite a paper constitute plagiarism? Continue reading When is a citation not enough?

Ketamine-depression paper retracted following investigation at Yale

A psychiatry journal has retracted a 2011 paper exploring the use of ketamine to treat patients with severe depression following an investigation at Yale University.

According to the retraction notice, Yale determined that the paper, published in the International Journal of Neuropsychopharmacology, did not accurately describe the research. But the study’s lead author, Gregory Larkin, says he believes the retraction “is wholly unnecessary, serving neither patients nor science.”

Case closed? Fired Pfizer researcher slated for seven retractions

Pfizer has discovered two additional papers that merit retraction from the lab of a former employee. One of the papers, published in Clinical Cancer Research, was retracted earlier this month.

Last year, Pfizer requested retractions of five papers from the lab of breast cancer researcher Min-Jean Yin, who was fired after an investigation revealed image duplication. The papers were first questioned on PubPeer. By April 2017, all five papers had been retracted.

After the initial probe, the pharmaceutical giant conducted a follow-up review of papers originating from Yin’s lab (which Leonid Schneider posted about on May 23). A spokesperson for the company told us that the review revealed two more articles that merited retraction “in light of data integrity issues relating to the figures therein.” The 2013 paper in Clinical Cancer Research was retracted earlier this month at Pfizer’s request. On May 1, 2017, Pfizer asked PLOS ONE to retract a 2013 paper. Continue reading Case closed? Fired Pfizer researcher slated for seven retractions

Former MD Anderson researcher objects to retraction of his paper

A cell biology journal has retracted a 2016 paper after an investigation revealed that the corresponding author failed to include two co-authors and acknowledge the funding source.

According to the retraction notice, the Journal of Cellular Physiology retracted the paper after the University of Texas, MD Anderson Cancer Center found that last author Jin Wang had omitted two researchers from the list of authors, and had also failed to acknowledge funding from the U.S. National Institutes of Health (NIH).

But Wang tells a different story. Continue reading Former MD Anderson researcher objects to retraction of his paper

“Data had been manipulated,” again: Swiss probe prompts two more retractions

A biologist at the University of Basel is retracting two papers, citing data manipulation uncovered during an institutional investigation. That investigation has already led to the retraction of a paper in Science Translational Medicine by some of the same authors earlier this year.

The two latest retractions, in the Journal of Biological Chemistry (JBC), share the same  corresponding author — Michael Sinnreich, based at University of Basel — and first author, Bilal Azakir, who is now an assistant professor at Beirut Arab University. The retraction notices cite an investigation at the University of Basel.

Here’s the retraction notice for “Proteasomal inhibition restores biological function of mis-sense mutated dysferlin in patient-derived muscle cells:” Continue reading “Data had been manipulated,” again: Swiss probe prompts two more retractions
