Tracking retractions as a window into the scientific process

Soon-to-be-ex-rector of top Belgium university blames coverage of misconduct case for ouster

with 3 comments

May was quite a month for Rik Torfs, the rector of a prominent university in Belgium. On May 9, Torfs lost his re-election campaign for rector of KU Leuven by a slim margin—out of more than 2100 votes, he lost by a mere 48. And just 20 days later, on May 29, Torfs wrote his final column for the Flemish daily newspaper De Standaard  — whom he believes was at least partly to blame for his election loss.

Specifically, it was the paper’s reporting on the university hospital’s (UZ Leuven) investigation into pediatric oncologist Stefaan Van Gool, which came just months before the election, that Torfs said he believes may have led to his ouster: Read the rest of this entry »

“Searching our souls”: Authors retract paper after researcher admits to fabricating data

without comments

Researchers at a prominent Japanese university have retracted a 2016 paper in a chemistry journal after the first author admitted to scientific misconduct.

According to the notice, Kyushu University investigated and verified that the first author had committed scientific misconduct.

We requested a copy of the misconduct report, which revealed that the researcher, Prasenjit Mahato, a postdoctoral fellow at Kyushu University who is no longer affiliated with the university, “admitted to falsifying research” in two papers on which he was first author: a highly cited 2015 paper in Nature Materials, which was retracted in 2016, as well as the 2016 paper in Journal of the American Chemical Society (JACS), retracted earlier this month. The university investigated and confirmed misconduct in both papers.

We covered the Nature Materials retraction last year, but at the time, the paper’s corresponding author, Nobuo Kimizuka, only told us that the “matter has been under investigation by the formal investigation panel of our University.”

According to the five-page misconduct report — which we translated from Japanese using One Hour Translation and is also available in Japanese on the university’s website — in July 2016, a member of the lab (“Faculty Member B”) began to suspect a problem after he reviewed the data with Mahato (“the defendant”): Read the rest of this entry »

Weekend reads: Death penalty for scientific fraud?; Why criticism is good; Cash for publishing

Can a tracking system for peer reviewers help stop fakes?

with 10 comments

Andrew Preston Credit: Victoria University of Wellington

The problem of fake peer reviews never seems to end — although the research community has known about it since 2014, publishers are still discovering new cases. In April, one journal alone retracted 107 papers after discovering the review process had been compromised. By tracking individual reviewers’ contributions, Publons — recently purchased by Clarivate Analytics — thinks that it can help curtail the problem of faked reviews. Co-founder and CEO Andrew Preston spoke to us about how it might work — and how the site has responded to recent criticism about accessibility to review data.

Instead of retracting a flawed study, a journal let authors re-do it. It got retracted anyway.

with 2 comments

When a journal discovers elementary design flaws in a paper, what should it do? Should it retract immediately, or are there times when it makes sense to give the researchers time to perform a “do-over?”

These are questions the editors at Scientific Reports recently faced with a somewhat controversial 2016 paper, which reported that microRNAs from broccoli could make their way into the nuclei of human cells — suggesting that the food we eat could affect our gene expression.

After the paper appeared, researcher Kenneth Witwer at Johns Hopkins — who was not a co-author — posted comments on PubMed Commons and the paper itself, noting that the authors hadn’t properly designed the experiment, making it impossible for them to detect broccoli microRNAs. 

But instead of retracting the paper, the journal decided to give the authors time to do the experiments again, this time with correctly designed molecular biology tools. When that failed, they retracted it — and as part of the notice, reported the exact opposite conclusion of the original.

Witwer said the authors did a “tremendous job” with the follow-up study, but he still thinks the journal should have retracted the paper immediately. Letting the authors redo it is “a dangerous precedent to set,” he told us:

Journal retracts two papers by authors who lifted others’ data

without comments

A journal has retracted two 2014 papers after the editors discovered the authors used data from other research groups without permission.

The papers, both published in the same issue of Cell Biochemistry and Biophysics and retracted in May, suffered from similar issues—the authors published data that was not theirs. The authors are all based at different institutions in China; as far as we can tell, the papers do not have any authors in common.

When we asked the publisher whether a third party, such as a paper mill, may have been involved, a spokesperson for Springer told us: Read the rest of this entry »

No new math: Journal pulls math paper with “already known” results

without comments

A mathematics journal has withdrawn a paper after discovering that the results were not new.

The paper, published online in March in Communications in Algebra, explored the properties of group rings, a discipline of algebra. According to editor-in-chief of the journal, Jason Bell, author Francis E. A. Johnson, a professor of mathematics at the University College London, devised a property associated with group rings, and defined it using the term “weakly finite.” But, at the time, Johnson was not aware that other experts had already defined the same property, using the term “stably finite.”

Bell, a professor of mathematics at the University of Waterloo in Ontario, and Lance Small, the journal’s other editor-in-chief, stressed that this issue was “definitely not a matter of plagiarism.” Bell and Small told us in a joint statement that “it was ultimately no one’s fault—it is just one of these things that can happen occasionally in mathematics research.” But given the overlap, the editors thought it best to withdraw the paper, they said: Read the rest of this entry »

12 years after researcher found guilty of misconduct, journal retracts paper

with 3 comments

In 2005, the U.S. Office of Research Integrity found an obesity researcher had engaged in scientific misconduct.

More specifically, the ORI report revealed that Eric Poehlman, then based at the University of Vermont, had “falsified and fabricated” data in 10 papers. The 2005 report asked that the journals issue retractions or corrections to the papers. By 2006, six of those papers were retracted (1, 2, 3, 4, 5, 6). In 2006, a judge sentenced Poehlman to one year and one day in prison for falsifying research data.

In 2015, we explored how long it takes a journal to retract a paper. We found that four of the 10 papers had still not been retracted — one appeared to be missing from Medline, another had received a correction (as the ORI report requested), and two had not been retracted or corrected (1, 2).

Until now. Read the rest of this entry »

Journal alerts readers to “technical criticism” of CRISPR study

with 6 comments

A Nature journal has posted a editor’s note to a recent letter on potential unintended consequences of CRISPR gene editing, after an executive at a company trying to commercialize the technology said the paper should be retracted.

The original article, published on May 30 as a correspondence in Nature Methods, suggested that using CRISPR in mice can lead to unexpected mutations. But last week, the journal added an “Editorial note” online. Nature Methods says the notice is not an expression of concern, which would be a stronger suggestion that the paper is problematic; it simply wants to alert readers to the fact that, as the note states:

German institute sanctions director after finding him guilty of misconduct

with 4 comments

The executive board of the Leibniz Association in Germany has reprimanded the director of its institute on aging for “grossly negligent scientific misconduct.”

Besides a written reprimand, the executive board has removed Karl Lenhard Rudolph’s “passive voting rights” in association committees, and excluded the institute under his leadership from receiving funds from a multi-million Euro internal funding competition, both for a period of three years.

The executive board identified problems in eight out of 11 reviewed papers, published between 2001 and 2016; it has asked Rudolph to retract one and issue errata for the others. The papers — some of which have been discussed on PubPeer — appear in journals such as Cell, Nature Cell Biology, and the EMBO Journal, and have been collectively cited 552 times, according to Clarivate Analytics’ Web of Science.

Rudolph is the director of one of the 91 independent research institutions that make up the Leibniz Association. He told us he is putting the position of Director of the Leibniz Institute on Aging – Fritz Lipmann Institute (FLI) in Jena “on hold” while he investigates the allegations:
