What Caught Our Attention: In the span of 48 hours, PLOS ONE retracted two papers this month that were co-authored by Bo Yu, based at Key Laboratories of Education Ministry for Myocardial Ischemia Mechanism and Treatment and The Second Affiliated Hospital of Harbin Medical University in China. Both notices cite multiple duplications and errors, and conclude:

Question: Do you value Retraction Watch? If so, would you consider a tax-deductible donation of $25, or a recurring donation of an amount of your choosing, to support us?
When researchers submitted a paper about a type of microparticle to PNAS, they wanted to give credit where it was due, and cite an unpublished manuscript that helped guide their work. But the journal’s policy forbid citing unpublished work, and the reference was removed before publication. Now, concerns from the authors of that unpublished work have prompted the journal to have a change of heart.
Continue reading PNAS wouldn’t let authors cite unpublished manuscript. Now, it admits it was wrong.
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.
Title: AMPA receptor-mediated regulation of a Gi-protein in cortical neurons
What Caught Our Attention: Usually, when journals publish corrections to articles, they also correct the original article, except when the original is unavailable online. When Nature noticed that some figure panels in a 20-year-old paper were duplicated, it flagged the issue for readers — but didn’t correct the online version of the original paper. According to the notice, the duplications don’t disturb the conclusion illustrated by the figure, the original data couldn’t be found, and the last two authors had retired. We contacted a spokesperson at Nature, who told us “the information at the start of the paper clearly links to the corrigendum.” Continue reading Caught Our Notice: Yes, a 20-year-old article is wrong — but it won’t be corrected online
A surgery journal retracted a 2014 paper last month after discovering that the study has “no scientific validity.”
Mario Schietroma and his coauthors, based at the University of L’Aquila in Italy, reported that giving patients high concentrations of oxygen during and after colorectal surgery significantly reduced their risk of infections. Although the authors reported significant p-values, the retraction notice states that, “upon recalculation, no p-values were close to significant.” The University of L’Aquila told Retraction Watch it is investigating, but did not provide details. Continue reading Paper used to support WHO guidelines on preventing infections “has no scientific validity”
A BMJ journal has retracted a 2017 paper that made a false claim about the clinical trial in question.
The Acupuncture in Medicine paper reported the results of a clinical trial about the impact of acupuncture and Chinese herbal medicine on stroke, gathered from one center. However, in November, the editors of the journal discovered that the authors had completed the trial at three centers, and had already published the data in Scientific Reports in 2016. The authors say the duplication and misrepresentation of the data stemmed from “confusion and misunderstanding.” Continue reading Authors claim clinical trial data came from one center. It came from three.
A researcher has retracted two 2014 papers, after discovering they had not gone through the proper approval process before being submitted.
The papers were part of a collaboration funded by the U.S. National Institutes of Health, which focused on solving protein structures. Adam Godzik, the senior author, told Retraction Watch that all papers had to be approved by a special committee before being submitted to a journal. Given the scale of the collaboration, the committee for the Joint Center for Structural Genomics (JCSG) would assess whether researchers who had made a previous contribution to the work should be added as authors.
Proteins: Structure, Function, and Bioinformatics retracted both papers after Godzik informed the editor in August 2014 that neither article had undergone the required review before being submitted to the journal. Although Wiley agreed to the retractions in an email to Godzik in September 2014, the papers were only pulled in January—more than three years later. Continue reading Author: “The retractions were about bureaucracy, not science”

What Caught Our Attention: Here’s a cut-and-paste issue that gave us pause. The authors of an 18-year-old paper in PNAS corrected it after realizing some bands in a figure were duplicated (an issue raised on PubPeer one year ago). It turns out, the first author had cut the paper into pieces and reassembled them to present the blots in the “desired order,” and some had become duplicated by mistake. The overall results were unaffected, so the journal swapped the image with a corrected version. Continue reading Caught Our Notice: “The first author cut the thermoprinter paper printout into pieces and reassembled them”
Over the objections of the authors, PLOS ONE has retracted a paper linking a diet designed to restore healthy gut bacteria to weight loss and other benefits.
The study, published in June 2017, claimed to show that a “Microbiome restoration diet improves digestion, cognition and physical and emotional wellbeing.” The diet was one championed by The Gut Makeover, whose author, Jeannette Hyde, is also a co-author on the paper (which the paper clearly disclosed). The diet is “designed to improve the health and diversity of the microbiome,” the microbiota that live within us.
The paper apparently prompted some criticisms, and even led one academic editor at PLOS ONE to resign. The journal now says “the conclusions of this study are not supported by the data presented,” and have retracted it. But the case may reveal more about the limitations of peer review at the journal than it does about any weaknesses of the study. Continue reading Journal retracts study linking “gut makeover” to weight loss, improved health
How much role did a potentially problematic paper play in the demise of a once-promising compound?
Researchers are questioning the validity of a high-profile article, published by Nature in 2006. Although the letter is 12 years old, the concerns have current implications: It was among the early evidence used to develop a cancer compound that recently failed a number of clinical trials.
It’s unclear whether the problems with the paper — if validated — could have contributed to the compound’s demise. But an outside expert has some thoughts — and so do image experts and multiple external reports, including one released this month, which agree the concerns about the figures have merit. (The first author’s ex-husband isn’t too happy with the article, either.)
