Here’s a tale of a paper retracted because other articles published years later seemed to plagiarize it – and its unhappy authors, whose behavior the journal says hints at paper mill activity.

On January 16 of this year, Maria Zalm, a senior editor at PLOS ONE and team manager for publication ethics, asked the authors of a 2015 paper to respond to concerns about their work – which had been flagged on PubPeer the previous November – by February 6, according to an email seen by Retraction Watch. After some apparent back and forth, Zalm wrote to the authors on March 6 to say the journal had decided to retract the article.

In October 2021, a Reddit user on the r/badscience subforum posted a long critique of an article published in PLOS ONE earlier that year that had analyzed the “anti-vaccination infodemic” on Twitter and concluded that former U.S. president Donald Trump was “the main driver of vaccine misinformation” on the platform before his account was suspended.

The critique, titled “Terrible PlosOne Paper Dissected,” listed concerns about the sample size (50 pro-vaccine and 50 anti-vaccine accounts), method of selecting the sample and control groups, and data analysis. The Redditor also looked at the reviews of the article which PLOS ONE made available, and concluded that “clearly neither reviewer actually read it in any detail.” 

The day after the comment was posted, an account for PLOS Communications responded, thanking the user “for your post publication peer review” and saying that PLOS ONE was looking into the article.

An article from 2019 that caught some media buzz – including from the New York Times – for its analysis of political speeches now bears an expression of concern that’s almost as long as the original paper. 

In “Liberals lecture, conservatives communicate: Analyzing complexity and ideology in 381,609 political speeches,” published in PLOS ONE, the authors concluded that “speakers from culturally liberal parties use more complex language than speakers from culturally conservative parties,” as they stated in their abstract. 

But after reading the article, linguist Joe McVeigh, a university teacher at the University of Jyväskylä in Finland, wrote an online comment on the article detailing “several fundamental and critical flaws in its methodology.” A key issue: applying the Flesh-Kincaid test, which was developed for assessing the readability of a written text, to political speeches. As McVeigh told us:

A gastroenterology research group led by a vice dean at a medical school has requested that a journal correct a paper with an image duplicated from an earlier study by the same group, Retraction Watch has learned. The journal has not yet determined what kind of notice to place on the article.

The group’s leader informed us of the correction request in emails asking us to remove a comment on a post from June pointing out the duplicated image. He also told us that he requested the correction before his employer received an allegation of research misconduct and started an inquiry, which found he and his group had not committed research misconduct. 

Uma Sundaram, vice dean of research and graduate education at the Joan C. Edwards School of Medicine of Marshall University in Huntington, W. Va. and chair of the department of clinical and translational science, is corresponding author on both of the papers that share an image. Sundaram also has a dual appointment at a VA medical center in Huntington.

In March, an editor at PLOS ONE noticed something odd among a stack of agriculture manuscripts he was handling. One author had submitted at least 40 manuscripts over a 10-month period, much more than expected from any one person. 

The editor told the ethics team at the journal about the anomaly, and they started an investigation. Looking at the author lists and academic editors who managed peer review for the papers, the team found that some names kept popping up repeatedly. 

Within a month, the initial list of 50 papers under investigation expanded to more than 300 submissions received since 2020 – about 100 of them already published – with concerns about improper authorship and conflicts of interest that compromised peer review.

A group of nutrition researchers in Canada led by the prominent diabetes scientist Emile Levy has lost three papers in PLOS ONE over concerns about the integrity of the data. 

The concerns were raised nearly eight years ago by Elisabeth Bik, early in her career as a data sleuth.  

In May 2014, Bik told us, she contacted the journal to point out problems with images in the articles, as well as a fourth paper that has received an expression of concern:

A researcher at the center of questions about a biotech’s controversial experimental treatment for Alzheimer’s disease has lost five papers in PLOS One. 

The journal says it is retracting the articles, by Hoau-Yan Wang and colleagues, over concerns about the integrity of the data and the images in the papers. Wang does not agree with any of the retractions.

As we’ve reported, Wang, of the CIty University of New York, helped conduct the studies that formed the backbone of the regulatory filing for the drug simufilam, which Cassava Sciences — formerly Pain Therapeutics — has been trying to bring to market. Cassava, according to a citizen’s petition to the FDA, has funded Wang’s lab for more than 15 years, and two of the now-retracted papers feature Lindsay Burns, a Cassava employee, as a co-author. (The citizen’s petition, which called on the FDA to halt Cassava’s trials, was filed by a law firm representing Cassava short sellers but eventually denied by the FDA because it was not an appropriate venue.)

After an author requested a slew of changes to a published paper, journal editors reviewed the study and spotted “additional concerns” that led to its retraction.

The study, titled “Pressure regulated basis for gene transcription by delta-cell micro-compliance modeled in silico: Biphenyl, bisphenol and small molecule ligand models of cell contraction-expansion,” was published in PLOS ONE on Oct. 6th, 2020. Its sole author was Hemant Sarin, a “freelance investigator in translational science and medicine” from Charleston, W.Va.

The study was pulled on March 25th with the following notice:

A group of researchers in Canada has retracted their 2018 paper on the gene sequence of the Arctic charr — a particularly hearty member of the Salmonidae family that includes salmon and trout — after discovering that the sample they’d used for their analysis was from a different kind of fish.

The paper, “The Arctic charr (Salvelinus alpinus) genome and transcriptome assembly,” appeared in PLOS ONE, and has been cited 29 times, according to Clarivate Analytics’ Web of Science. Per the abstract:
