Author cops to “randomly” choosing data for figures in paper, colleagues say

On April 17th, Mathieu Bollen, a researcher at KU Leuven in Belgium, received a notice from PubPeer: A paper he had published in 2013 appeared to have data duplications.

The article, “Maternal Embryonic Leucine Zipper Kinase (MELK) Reduces Replication Stress in Glioblastoma Cells,” published in the Journal of Biological Chemistry, offered an explanation for why elevated levels of the MELK protein are associated with growth of a particular kind of brain tumor, glioblastoma. Several clinical trials are investigating MELK inhibitors as cancer treatments.

Bollen, the paper’s corresponding author, told Retraction Watch that one instance of image duplication, the inclusion of a gel-band from an unrelated experiment to represent a control, was “worrisome” but easily explainable:

“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

Engineering journal removes article co-authored by former president of Iran

Does failing to disclose that you were once a leader in the “Axis of Evil” deserve retraction?

An engineering journal has pulled a 2017 paper whose authors included Mahmoud Ahmadinejad, former president of the Islamic Republic of Iran.

Ahmadinejad, the notorious anti-Semitic and anti-West president of Iran from 2005 to 2013, was a civil engineer before entering politics — and remained active in the field while serving in government. But his failure to note his old day job appears to have cost him a paper in the electronic edition of the Institute of Transportation Engineers (ITE) Journal.

Carlo Croce, OSU cancer researcher under investigation, retracts paper

Carlo Croce

A researcher whose work has come under repeated scrutiny has retracted a 2008 paper for “errors that occurred in the construction” of various figures.

Carlo Croce, the corresponding author of the newly retracted paper, has been dogged by misconduct accusations for years — as recently described in the New York Times. His employer, The Ohio State University, has recently re-opened an investigation into his work. Seven of his papers have now been retracted, and fourteen have been corrected for image and text issues such as manipulation, duplication, and errors, as well as two others earning expressions of concern.

Here’s the retraction notice for “Fhit Interaction with Ferredoxin Reductase Triggers Generation of Reactive Oxygen Species and Apoptosis of Cancer Cells,” in the Journal of Biological Chemistry: Continue reading Carlo Croce, OSU cancer researcher under investigation, retracts paper

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.

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

Weekend reads: An NIH grant scam; are calls for retraction useful?; how to end honorary authorship

The week at Retraction Watch featured the revocation of a PhD, a questionable way to boost university rankings, and a look at what editors should do when a researcher known to have committed misconduct submits a new manuscript. Here’s what was happening elsewhere: Continue reading Weekend reads: An NIH grant scam; are calls for retraction useful?; how to end honorary authorship

Publisher flags paper on same-sex parenting after neo-Nazi group cites it

A publisher has issued an expression of concern (EoC) about a study that claimed children with same-sex parents were at greater risk of depression and abuse, after posters using statistics from the paper to support a homophobic message appeared in Australia and the US.

On Aug. 21, several news websites reported that these posters were appearing in Melbourne, Australia, citing claims from a 2016 paper published in Depression Research and Treatment, which said that children with same-sex parents are more at risk for depression, abuse, and obesity than children with opposite-sex parents. The poster had also appeared previously in Minneapolis and has been traced to a neo-Nazi group, as reported by HuffPost Australia. Australia is preparing for a national, non-binding, mail-in vote on whether to provide marriage equality for same-sex couples.

The EoC mechanism, which was chosen by the journal’s publisher, Hindawi, is an unusual choice here. The paper’s author, D. Paul Sullins, a sociology professor at The Catholic University of America and the paper’s author, told Retraction Watch that Hindawi contacted him Aug. 21 about the decision. Initially, he told us he didn’t have any “particular objection to it,” but later told us he changed his mind after he read more about COPE’s guidelines for EoCs: Continue reading Publisher flags paper on same-sex parenting after neo-Nazi group cites it

Updated: Ohio State revokes PhD of co-author of now-retracted paper on shooter video games

Jodi Whitaker, via University of Arizona

[This post, which at 1200 UTC 8/25/17 originally reported on the then-upcoming vote, has been updated at 1800 UTC 8/25/17 to include the results of the vote.]

A researcher who co-authored a paper about video games that was retracted earlier this year has had her PhD from The Ohio State University revoked.

As WOSU reported this afternoon, the vote today of the university’s Board of Trustees was unanimous. The scheduled vote on whether to revoke Jodi Whitaker’s degree was first reported yesterday by The Columbus Dispatch.

While a graduate student at Ohio State, Whitaker was co-author of a paper that claimed to find that first-person shooter video games improved marksmanship. As we’ve reported, the paper, published online in 2012, was retracted earlier this year, two years after a university committee was alerted to irregularities in the data by two outside researchers.

The controversy over the paper became heated at times. Continue reading Updated: Ohio State revokes PhD of co-author of now-retracted paper on shooter video games
