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

Researcher loses battle with Cell over wording of retraction notice

For months, a researcher has wrestled with a journal over the wording of an upcoming retraction notice. It appears that she has lost.

Earlier this week, Cell retracted the paper, despite the protests of first author Shalon Babbitt Ledbetter. When Ledbetter learned the journal was planning to retract the biochemistry paper over image manipulations, but wouldn’t name the culprit in the notice, she shared her concerns on PubPeer. Although a 2015 letter sent to Cell from Saint Louis University identified last author Dorota Skowyra as responsible for multiple manipulations, the journal wasn’t planning to say Skowyra was responsible in the retraction notice. Which would leave all other authors — particularly Ledbetter — under a cloud of suspicion.

Now, Cell Press has finally retracted the paper, along with another paper in Molecular Cell that lists Skowyra as corresponding author. Both notices describe image manipulations that were investigated by Saint Louis University (SLU). Neither identifies who is responsible.

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

That study reporting worrisome levels of zinc in tuna? It’s being retracted

Recently, a rash of news outlets posted concerns that canned tuna and other products may contain potentially dangerous levels of zinc. They were all wrong.

News outlets such as The Daily Mail and The Sun reported findings from a recent study, which showed that canned foods such as tuna may contain 100 times the daily limit of zinc — raising concerns about how such huge doses of the mineral could be causing digestion problems. The last author of the study told Retraction Watch the paper is going to be retracted, because the authors made a fundamental error calculating the amount of zinc present in canned foods.

Last week, the UK’s biggest health website NHS Choices posted a critique of the paper, in which they recalculated the levels of zinc present in canned foods:

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:

“Youth Guru” loses turkey-neck paper that overlapped with book chapter

Ronald Moy

A prominent cosmetic surgeon and his daughter have lost a 2017 paper on treating men with excessive neck flab — otherwise known as “turkey neck” — because much of the work appears to have duplicated a book chapter he co-authored about the topic.

The first author of the retracted article is Ronald L. Moy, a plastic surgeon to the stars in Beverly Hills, Calif., and a past president of both the American Academy of Dermatology and the American Society of Dermatology. In a 2012 article about area plastic surgeons, LA Confidential Magazine dubbed Moy the “youth guru” and a local leader in the use of “new research and a comprehensive approach to restore a youthful complexion—no cutting required.”

His co-author was his daughter, Lauren Moy, who appears to be working with him in his Rodeo Drive dermatology practice.

Don’t like a paper, but don’t want to retract it? Just issue an “editorial statement”

Last April, the American Journal of Epidemiology and the American Journal of Public Health published a rare joint editorial statement. It concerned a pair of papers on the topic of mortality and obesity. Several complaints had prompted the journals to investigate. Their assessment: These papers contained inaccurate results.

The statement was not a retraction—it was a compromise the editors came up with that would set the academic record straight, while not tainting the authors’ publication record, given that they had (in the editors’ opinion) made honest mistakes. It was an unusual solution to a not-uncommon problem (criticisms of a paper), in which the editors tried to balance their duty to the scientific record against its potential impact on the authors. And it left few people happy — including researchers in the field, who are left unsure about the validity of the results.

Roland Sturm, an economist at Pardee RAND Graduate School who was not a co-author on the papers, told Retraction Watch:

Caught Our Notice: Forged email for corresponding author dooms diabetes paper

Title: Naringin Alleviates Diabetic Kidney Disease through Inhibiting Oxidative Stress and Inflammatory Reaction

What Caught Our Attention: PLOS ONE had a few reasons for retracting a 2015 paper about a treatment for kidney disease due to diabetes: For one, despite what the paper claims, the authors did not obtain ethical approval to conduct the reported animal experiments. In addition, the corresponding author had no idea the paper had been submitted and published. How could a corresponding author be kept in the dark? It turns out, the journal was given an incorrect email address for him, so he didn’t receive any communications around the paper. (One author apparently used a third party editing company.)

Whoops: Authors didn’t mean to include new data in article about transgender identity

Here’s something we don’t see that often — authors retracting one of their articles because it included new data.

But that is the case with a 2017 review exploring the potential genetic and hormonal underpinnings of gender identity.  The authors Rosa Fernández García and Eduardo Pásaro Mendez told Retraction Watch that they asked bioethics journal Cuadernos de Bioética to withdraw their review after realizing it “indirectly” mentioned some of their unpublished work. According to García, the authors had hoped to publish the new data in a scientific paper before the review came out, but the review ended up being published first.  

Here’s the retraction notice for “Is Sexual Identity Optional? A Study of The Genetics of Transsexuality:”
