UPDATED: Elsevier retracts a paper on solar cells that appears to plagiarize a Nature journal. But the reason is…odd.

The similarities between recent papers in two different journals about energy were striking — so striking that a number of people have taken to Twitter and Facebook to let the world know about them.

[1415 UTC, August 29, 2018: See update at the end of this post.]

One paper, “Systematic investigation of the impact of operation conditions on the degradation behaviour of perovskite solar cells,” was authored by a group of researchers in Lausanne, Switzerland and appeared on January 1, 2018 in Nature Energy. Its abstract reads: Continue reading UPDATED: Elsevier retracts a paper on solar cells that appears to plagiarize a Nature journal. But the reason is…odd.

How much cancer stems from diabetes, obesity? Lancet journal swaps high-profile paper

Six months ago, the media was ablaze with the findings of a new paper, showing that nearly six percent of cancer cases are caused, at least in part, by obesity and diabetes. But this week, the journal retracted that paper — and replaced it with a revised version.

The new paper doesn’t change the main findings much — the share of all cancers attributable to diabetes and obesity changed from 5.6% to 5.7%, which wouldn’t change any headlines about the original paper. But soon after the paper was published, a group of researchers noticed the authors’ mistake — which was significant enough to prompt the journal to retract the paper entirely, and swap it with a new one.

According to first author Jonathan Pearson-Stuttard at Imperial College London:

Caught Our Notice: A team from Harvard, Cornell, Cambridge, HHMI, and UCSF can’t reproduce a paper’s findings

What Caught Our Attention: Any time there’s an issue with a paper co-authored by researchers from such high-profile institutions as Harvard, Cornell, and the University of Cambridge, we take notice. In this case, the group — which included Laurie Glimcher, then-dean at Cornell, now president of the Dana-Farber Cancer Institute — chose to retract a 2013 paper from a Cell journal after learning they couldn’t reproduce some of the experiments.

Chemists duke it out over who was first to discover a 30-year-old technique

Decades ago, unbeknownst to each other, two chemists were independently working on a screening approach to identify new potential drugs. Both published papers about the technique around the same time. So now, when scientists write papers that cite the technique, who should get credit for discovering it?

Decades later, that question still hasn’t been answered — and the researchers continue to argue, this time over one’s decision not to cite the other’s work.  

More than 30 years ago, Árpád Furka—now retired from Eötvös Loránd University in Budapest—developed an approach he says has had “outstanding importance” in drug development. The technique, called split-mix synthesis, made it possible to synthesize and screen millions of peptides at once, instead of one by one. Furka patented the method in 1982, presented an abstract in 1988, and published a paper in 1991. Continue reading Chemists duke it out over who was first to discover a 30-year-old technique

Author under fire has eight papers retracted, including seven from one journal

A researcher whose work on the use of nanomaterials has been heavily scrutinized on PubPeer — with one critic alleging a paper contained “obviously fabricated” images — has lost eight papers. [Editor’s note: See update below.]

The eight articles — seven from Biosensors and Bioelectronics and one from Analytica Chimica Acta, both published by Elsevier — all cite issues related to duplications, and conclude with some version of the following:

Flawed climate science paper “exposed potential weaknesses” in the peer review process

Before we present this new post, a question: Do you enjoy reading Retraction Watch? If so, we could really use your help. Would you consider a tax-deductible donation to support our work? Thanks in advance.

How did a deeply flawed paper, which contradicts mainstream science on climate change, pass peer review?

That is what three editorial board members tried to figure out after the journal, Global and Planetary Change, faced heavy criticism for publishing the controversial paper last year. The board members published their findings earlier this month in a commentary.

Martin Grosjean, the corresponding author on the editorial, told Retraction Watch that the editors and publisher, Elsevier, share the same interest: Continue reading Flawed climate science paper “exposed potential weaknesses” in the peer review process

Nutrition paper claims intervention cuts child obesity. Experts disagree.

Does incorporating gardens and their harvest into school-based nutrition programs help children get healthier? A 2017 paper claims it does, but a group of outside experts disagrees — strongly.

The 2017 paper reported that adding gardens to schools and teaching kids how to cook the harvest, among other elements, helped kids learn about nutrition — and even improved their body mass index, a measure of body weight.

However, soon after the paper appeared, a group of outside experts told the journal the data reported by the paper didn’t support its conclusions — namely, the authors hadn’t shown that the intervention had any effect. The authors performed an inappropriate analysis of the data, the critics claimed, and the paper needed to be either corrected or retracted outright.

But the Journal of Nutrition Education and Behavior has not amended the paper in any way. Instead, last month, it published the outside experts’ criticism of the paper, including their explicit calls to either correct or retract it, along with the authors’ response to the critics.

David Allison, the last author on the critical letter and the dean of the school of public health at Indiana University Bloomington, said he was surprised to see the journal chose to publish his critical letter, but not alter the paper itself:

Caught Our Notice: Researcher who sued PubPeer commenter up to 21 retractions

Titles: 1) Notch-1 induces Epithelial-mesenchymal transition consistent with cancer stem cell phenotype in pancreatic cancer cells

2) Sensitization of squamous cell carcinoma to cisplatin induced killing by natural agents

What Caught Our Attention: Regular readers will be familiar with the saga involving Fazlul Sarkar and PubPeer: In 2014, Sarkar sued anonymous commenters on the site, claiming defamation (and that damaging comments may have cost him a new job). Although Sarkar won an initial ruling, it was overturned by an appeals court. In the midst of that, the ACLU (which represented PubPeer in the case) released a copy of a misconduct investigation report compiled by Sarkar’s institution, Wayne State University, which concluded that he had committed enough misconduct to warrant retracting 40 papers. The two latest notices, both of which cite Wayne State’s investigation, bring Sarkar’s total to 21.   Continue reading Caught Our Notice: Researcher who sued PubPeer commenter up to 21 retractions

Can soil science research dig itself out from a citation stacking scandal?

Jan Willem van Groenigen

Last year, the soil science community was rocked by reports that an editor, Artemi Cerdà, was accused of citation stacking — asking authors to cite particular papers — boosting his profile, and that of journals where he worked. (Cerdà has denied the allegations.) The case had some major fallout: Cerdà resigned from two journals and the editorial board of Geoderma, additional editors resigned from their posts, and a university launched an investigation. In the midst of the mess, a group of early career scientists in the field released an open letter, urging the leaders of the community “to establish a clear road map as to how this crisis will be handled and which actions will be taken to avoid future misconducts.” Today, Jan Willem van Groenigen, Chair of the Editors in Chief of Geoderma, along with other editors at the journal, published a response to those letter-writers — including a list of the 13 papers that added 83 citations the journal has deemed “unwarranted.” The editorial includes a list of “actions we have taken to prevent citation stacking from recurring and to further strengthen the transparency of the review process” — including monitoring editors and showing authors how to report suspicious conduct.

Retraction Watch: It’s been nine months since the young researchers released their open letter — why respond now?

“Absolutely mortified” after unintentionally plagiarizing, author offers to step down from new post

A few months ago, Dirk Werling discovered he had made a horrible mistake: He had inadvertently plagiarized in his recent review.

On January 20, Werling said he came across a 2016 paper while working on a grant and realized he had published some of the text in his 2018 review in Research in Veterinary Science. Werling — based at Royal Veterinary College at the University of London — told Retraction Watch:

I knew I needed to retract my paper.
