“An example for all authors to uphold:” Researcher logs 5 corrections

A scientist in Ireland has corrected five of his papers in a single journal dating back more than a decade, after image-related problems were brought to his attention.

Four of the newly corrected papers have a common last and corresponding author: Luke O’Neill of Trinity College Dublin in the Republic of Ireland. O’Neill is also a co-author of the remaining paper that was fixed. O’Neill told us the mistakes were a “bit sloppy,” noting that he takes responsibility for the errors in the four papers on which he is last author.

O’Neill forwarded Retraction Watch a comment he received from Kaoru Sakabe — data integrity manager at the American Society for Biochemistry and Molecular Biology (which publishes The Journal of Biological Chemistry (JBC)) — that reads:

Dear Peer Reviewer: Could you also replicate the experiments? Thanks

via the University of St Andrews

As if peer reviewers weren’t overburdened enough, imagine if journals asked them to also independently replicate the experiments they were reviewing? True, replication is a big problem — and always has been. At the November 2016 SpotOn conference in London, UK historian Noah Moxham of the University of St Andrews in Scotland mentioned that, in the past, some peer reviewers did replicate experiments. We asked him to expand on the phenomenon here.

Retraction Watch: During what periods in history did peer reviewers repeat experiments? And how common was the practice? Continue reading Dear Peer Reviewer: Could you also replicate the experiments? Thanks

Japan group earns 4th retraction following investigation

Researchers in Japan have issued their fourth retraction, noting that the same figures were used to depict different experimental conditions.

The group lost two papers in 2015 for the same reason, following a misconduct investigation at Oita University in Japan. Last year, the same group notched another retraction, and pegged the responsibility for the problematic figures on first author Satoshi Hagiwara.

Now, the group has published a fourth retraction in the European Journal of Pharmacology; the latest notice doesn’t identify a culprit. All four retracted papers list Hagiwara as first author.

Here’s the latest retraction notice: Continue reading Japan group earns 4th retraction following investigation

Plant journal flags fungus paper amid investigation

A journal has issued an expression of concern (EOC) for a recently published study after a probe identified “problems with the figure presentation.”

According to the EOC notice in New Phytologist, two figures in the paper contained “some anomalies,” and the corresponding author has acknowledged that there are problems with the images.

Here’s the EOC notice: Continue reading Plant journal flags fungus paper amid investigation

Authors use same images in two studies — one is retracted, the other flagged by journal

After researchers in China included the same images in two papers published online one month apart, one paper has been retracted, and the other flagged with an expression of concern. 

According to the retraction notice in the International Journal of Molecular Medicine (IJMM), the authors intended that the two different papers offered “different research perspectives.”

Meanwhile, the Chinese Medical Journal — which published the same images one month later — has issued an expression of concern (EOC), noting it “should not be considered as a statement regarding the validity of the work.” Both papers describe how cells regulate blood flow to the retina.

Normally, journals choose to retract the most recent paper containing duplicated images, but in this case, the IJMM paper was published online in February 2016, and the Chinese Medical Journal in March.

Here’s the retraction notice: Continue reading Authors use same images in two studies — one is retracted, the other flagged by journal

Researcher loses 4th paper flagged by misconduct probe

A researcher in Germany has logged her fourth retraction following an investigation by her former employer that found evidence of scientific misconduct.

The latest retraction for Tina Wenz in the Journal of Applied Physiology mentions the probe at the University of Cologne in Germany, which recommended retracting six of her papers. One had already been retracted by the time the report was released; last month, we reported that two others had been pulled. Now, we’ve come across a fourth.

Here’s the latest retraction notice: Continue reading Researcher loses 4th paper flagged by misconduct probe

EMBO journals retract figures in two papers missing source data

Journals published by the European Molecular Biology Organization (EMBO) have retracted a handful of figures in two papers with the same last and first authors.

After some figures in the 2005 and 2007 papers were flagged on PubPeer and the authors couldn’t provide the original data, the journals decided to retract parts of the papers, since other data supported the remaining conclusions, according to the Head of Scientific Publications at EMBO.

The partial retractions are labeled as corrigenda by the journals. Earlier this year, the U.S. National Library of Medicine (NLM) announced it would be classifying partial retractions as errata, noting they had been used so rarely by journals.

Both lengthy corrigenda (also reported by Leonid Schneider) contain statements from the authors and the editors. The statements from the authors provide detailed explanations about the problems with the figures in question; here’s an excerpt from the editor’s statement in The EMBO Journal corrigendum: Continue reading EMBO journals retract figures in two papers missing source data

U.S. gov’t physicist sentenced to 18 months in prison for fraud

A physicist formerly based at the Lawrence Livermore National Laboratory (LLNL) in California has been sentenced to 18 months in prison for faking data. 

According to the United States Attorney’s Office in the Northern District of California, after receiving millions in government funding between 2008 and 2012, Sean Darin Kinion submitted faked data and reports to make it seem like he’d performed quantum computing work. Kinion pled guilty in June, 2016 to “a scheme to defraud the government out of money intended to fund research.” He has also been ordered to pay back $3,317,893 to the government.

As readers may know, scientists who commit misconduct are rarely sentenced to prison, although there are some exceptions — most notably, Dong-Pyou Han, who last year was sentenced to nearly five years in prison (and pay back $7 million) after spiking rabbit blood samples to make a HIV vaccine look more effective.

Lynda Seaver, director of public affairs at the LLNL, told us Kinion was dismissed in February 2013, following an investigation that found “some discrepancies in his work.”

Researcher logs three retractions for image duplications — two of which with familiar co-authors

A researcher in Brazil is taking responsibility for accidentally mixing up images in three papers in the Journal of Biological Chemistry. 

The corresponding author on the three papers told us the mistake happened because the studies were conducted simultaneously, and relied on one computer.

There’s a side note to these retractions: The co-author list on two papers includes names that should be fairly well-known to our readers — Mario Saad, the researcher who unsuccessfully sued the American Diabetes Association to stop retractions of his papers, and Rui Curi, a researcher whose legal threats assisted in the shutdown of Science-Fraud.org. This makes Saad’s ninth retraction.

According to the retraction notices, Lício Velloso  — who, like his co-authors, is based at the University of Campinas in São Paulo, Brazil — assembled all the figures. He told Retraction Watch that the authors initially wanted to correct the papers, adding: Continue reading Researcher logs three retractions for image duplications — two of which with familiar co-authors

Journal cleans the house by retracting 6 cancer papers for plagiarism

Following an investigation, a genetics journal has pulled six cancer papers published this year for plagiarizing from other sources.

According to an excerpt from the retraction notice in Genetics and Molecular Research, the journal has “strong reason to believe that the peer review process was [a] failure,” and has alerted the authors’ institutions.

The notice announcing the retraction of all six papers begins: Continue reading Journal cleans the house by retracting 6 cancer papers for plagiarism
