Authors retract two plant biology papers over duplicated images

Plant scientists have issued two retractions after noticing several images had been duplicated within and across the papers.

The papers both appeared in March 2002 in The Plant Cell and The Plant Journal.

The last author on both papers — Jonathan Jones, a professor and group leader at The Sainsbury Laboratory in Norwich, UK — took responsibility for the duplications. He told us:

As last author I was responsible for checking the papers but did not notice the similarities between figures in the different papers.  I regret this and took action as soon as I realized there was an issue. Both papers went through peer review and the issue was not picked up at that point either.

Susana Rivas, the first author on both papers, has collaborated with beleaguered plant scientist Oliver Voinnet — and was a second author on one of his eight retractions (which we covered here).

The editor-in-chief of TPJ Christoph Benning said that, after the authors contacted them, the journals looked into the issue, confirmed the duplications and then retracted the papers: Continue reading Authors retract two plant biology papers over duplicated images

“Clumsy but genuine errors” prompt PNAS correction

Some accidental mistakes have led researchers to issue a long correction to a 2016 PNAS paper.

According to the notice, when the cell biology paper’s corresponding authors became aware of duplications in two images, they immediately notified the journal and the University of Nottingham. After examining the original data archives, the university found that the authors generated the correct images, but the person who prepared the figures selected the wrong images from the data archive.

According to John Atherton, faculty pro-vice-chancellor for the Faculty of Medicine and Health Sciences at the University of Nottingham in the UK, who oversaw the investigation: Continue reading “Clumsy but genuine errors” prompt PNAS correction

Drug researcher up to ten retractions

A pharmaceutical researcher has received his tenth retraction. The reason, once again: duplicating his previous work.

Giuseppe Derosa, based at the University of Pavia in Italy, lost a 2011 paper this month after journal editors identified “substantial duplication of an earlier published paper.” According to the notice, the authors failed to cite the previous work and to disclose that the manuscript had been published or was under consideration elsewhere.

Derosa has a habit of reusing clinical trial data in multiple papers. He received his first four retractions in 2015 for publishing the same clinical trial results six times—two of those papers were retracted over the summer and two more several months later. By 2016, a fifth from the bunch was retracted (one of the six still stands). Derosa received another retraction, citing duplication (which we covered here and which was not related to the six clinical trials).

Paper with duplicated image “sequentially builds” on neuroscience work, authors argue

A neurochemistry journal has retracted a paper from a group in China over a duplicated image.

According to the notice, the authors used the same image in the two papers to represent different experimental conditions. The only distinguishing feature between the images: “apparent brightness changes.”

The authors defended their actions, explaining that the research published in Journal of Neurochemistry “sequentially builds” on their previous study in Journal of Neuroinflammation, which they mention in the 2015 paper’s discussion. In the notice, the authors were quoted saying:  Continue reading Paper with duplicated image “sequentially builds” on neuroscience work, authors argue

Journal retracts nine papers in one day by author under investigation at the Weizmann Institute

On April 27, the Journal of Biological Chemistry (JBC) retracted nine papers by a researcher based in Israel, including some dating back to 2000.

The reason: Image manipulation.

Michal Neeman, vice president of The Weizmann Institute of Science, told us that the researcher, Rony Seger, is under investigation following an allegation of misconduct affecting papers in multiple journals.

So far, we’ve found 11 retractions for papers by Seger, a molecular biologist. In the notices, the authors state they have “full confidence” in the findings, and in many instances have replicated the work.

According to Neeman:

Journal flags two more papers by diabetes researcher who sued to stop retractions (and now has 12)

A diabetes journal has issued two notices of concern for papers co-authored by a researcher who took another publisher to court after it did the same thing — but ultimately lost.

The notices are for two papers co-authored by Mario Saad — who, after losing his legal battle with the American Diabetes Association, has since accumulated 12 retractions. Both notices — from the journal Diabetologia, published by Springer and the the European Association for the Study of Diabetes (EASD) — say they have alerted Saad to their concerns about some of the images in the papers, and the university where he is based was asked to investigate more than one year ago. Since the journal has not yet received any information from the University of Campinas in Brazil, however, it decided to issue expressions of concern for the two papers.

Here’s the text of the first notice:

First author objects to retraction (his fourth) in chemistry journal

The first author of a 2013 chemistry paper is objecting to his co-authors’ decision to retract the paper, which contains duplicated figures.

We recently encountered a similar scenario with papers by first author Khalid Mahmood. In late 2015, Mahmood lost three papers in the journal ACS Applied Materials & Interfaces over duplicated images. One of the notices also indicated that the figures had “been published elsewhere and identified with different samples” — the same language used in the notice of the most recent retraction, in Journal of Materials Chemistry C.

Mahmood performed the work on the papers at Korea Advanced Institute of Science and Technology (KAIST), along with his two co-authors, Seung Bin Park and Hyung Jin Sung (also co-authors on two of the retracted papers in ACS Applied Materials & Interfaces).

Seung Bin Park, who is dean of the College of Engineering at KAIST, told us: Continue reading First author objects to retraction (his fourth) in chemistry journal

Journal: Here’s why we didn’t retract this duplicated paper

Here’s something we don’t see every day: A journal explains in an erratum notice why it chose not to retract a paper that contains data published elsewhere.

According to the Journal of Business and Psychology, the authors violated the journal’s transparency policy by failing to disclose that they’d used the same data in their 2014 in three others. However, the editors ultimately concluded the current paper was different enough from the other three to save it from being retracted.

Here’s the erratum: Continue reading Journal: Here’s why we didn’t retract this duplicated paper

Controversial researcher loses 12th paper that’s “literally copied;” authors object

A physics journal has retracted a 2011 paper by a group of scientists based in Italy, noting it’s “literally copied” from a paper by the same authors.

This is the 12th retraction for the paper’s first author Alberto Carpinteri, who is known in the engineering community for championing some controversial ideas, such as that the Shroud of Turin is as old as Jesus (contradicting carbon dating). In 2015, a journal he used to edit — Meccanica — retracted 11 of his papers, noting that “the editorial process had been compromised.”

In the latest notice, the Journal of Statistical Mechanics: Theory and Experiment (JSTAT) says its investigation found a substantial portion of the paper—including the main analysis and conclusion—had been lifted from a paper published in another journal several months before.

Last author of the latest paper to be retracted, Amedeo Manuello Bertetto from Polytechnic University of Turin, told us the authors strongly opposed the journal’s decision:  Continue reading Controversial researcher loses 12th paper that’s “literally copied;” authors object

Top physicist loses another paper; tally now up to 7

A physics journal has retracted a paper from a leading physicist in India over duplication.

The paper’s first and corresponding Naba K. Sahoo has had six papers retracted for the same reason — four earlier this year and two last year.

The new retraction brings Sahoo’s total to seven, by our count.

The duplication allegations began several years ago, after Sahoo’s colleagues at Bhabha Atomic Research Centre (BARC), part of Indian government’s Department of Atomic Energy, accused him of plagiarizing his own work.

Thomas Lippert, editor-in chief of Applied Physics A: Material Science & Processing, told us: Continue reading Top physicist loses another paper; tally now up to 7
