Our list of retracted or withdrawn COVID-19 papers is up past 500. There are more than 60,000 retractions in The Retraction Watch Database — which is now part of Crossref. The Retraction Watch Hijacked Journal Checker now contains more than 300 titles. And have you seen our leaderboard of authors with the most retractions lately — or our list of top 10 most highly cited retracted papers? What about The Retraction Watch Mass Resignations List?

Taylor & Francis threatens legal action against anonymous group’s ‘highly defamatory’ claims

Taylor & Francis has threatened legal action against an online group that has made allegations, based largely on vague insinuations rather than evidence, about the publisher and a member of its research integrity team.

The group, ScienceGuardians, is an anonymous organization whose website serves as what they call an online “journal club.” On X, it has been posting so-called “investigations” of several sleuths, publishers and organizations, what it calls “perpetrators of the PubPeer Network Mob.” Its targets have included sleuths Kevin Patrick and Reese Richardson, and others such as Science editor-in-chief Holden Thorp, and its posts are often amplified by those whose work has been questioned on PubPeer or retracted.

On September 7, the group published a string of claims on X about Nick Wise, a sleuth who joined Taylor & Francis in January as a research integrity manager. The ScienceGuardians post characterized the move as Wise “infiltrated” the publisher’s research integrity office. The post states he is responsible for 1,300 posts on PubPeer (which we have noted he does under his real name), and, ScienceGuardians claims, more than 100 others under the name “Simnia avena.”

Authors defend retracted paper on vitamin D and COVID-19 called ‘deeply bizarre’ by critic

PLOS One has retracted a paper linking vitamin D levels and COVID-19 morbidity three years after a critic flagged the data in the study as “deeply bizarre.” The authors objected to the retraction, with one calling it “outrageous” and pointing to flaws in the published notice.

The article, which appeared in February 2022, claimed people with low levels of vitamin D were at increased risk for severe COVID-19 and were more likely to die of the disease than other patients. It has been cited 65 times, according to Clarivate’s Web of Science.

The paper had a “huge, immediate impact,” said Gideon Meyerowitz-Katz, a senior research fellow from the University of Wollongong in Australia, citing the fact that the paper had been viewed over 1 million times within six weeks of being published. The article joins others, many also flagged by Meyerowitz-Katz, purporting to find links between vitamin D intake and COVID-19 severity that have been retracted or removed.

Math has publication fraud, too

Scholarly publishing in mathematics is unlike many other fields, marked by fewer papers, fewer coauthors per paper and fewer citations. But that doesn’t mean the field is immune to fraud and cheating.

A pair of papers posted to the arXiv addresses the issue of fraudulent publishing in math, particularly metrics gaming, and offers a list of recommendations to help detect and deal with that problem and other fraudulent activities. (The former was also published in the October AMS Notices; the latter will appear in the November issue.) “Fraudulent publishing undermines trust in science and scientific results and therefore fuels antiscience movements,” mathematician Ilka Agricola, lead author of both papers, told Retraction Watch.

A professor of mathematics at Marburg University in Germany, Agricola was president of the German Mathematical Society in 2021-2022 and is chair of the Committee on Publishing of the International Mathematical Union. The new articles are the products of a working group of the IMU and the International Council of Industrial and Applied Mathematics.

Study on apple cider vinegar for weight loss retracted after many raise concerns

Easy fixes for complex health problems can be tempting — but they rarely pan out. That seems to be the case for the investigators on one clinical trial who claimed consuming apple cider vinegar caused obese teens and young adults to lose weight.

Their article appeared in March 2024 in BMJ Nutrition, Prevention & Health. The journal is retracting the paper “because the authors’ analyses could not be replicated and multiple errors were identified,” according to the retraction notice.

The retraction, dated September 23, comes more than a year after sleuths pointed out some of these errors and other problems with the analysis.

Second study using ‘Tin Man Syndrome’ X-ray under scrutiny following Retraction Watch inquiry

An altered image posted as an April Fool’s joke (left) was used as a figure (right) in a 2021 paper in *Scientific Programming*.

Just as The Wonderful Wizard of Oz was the first of 14 books in a series, our recent coverage of a paper on “Tin Man syndrome” seems to have sequels. After we wrote about a case study describing a man with his heart in his abdomen retracted for plagiarizing images from an April Fools’ joke, a reader flagged yet another paper using the same image.

As we previously reported, the authors of a “rare case report” appearing in Medicine claimed they had encountered a case of a man with asymptomatic “ectopia cordis interna,” in which his heart was in his abdomen. After the article was retracted, the corresponding author admitted the photos had been taken from a 2015 April Fools’ paper in Radiopaedia describing the same (fictitious) condition.

Following that coverage, a reader did a reverse image search of the X-ray in both papers and found a 2021 article from Scientific Programming, published by Wiley. The study recommends a non-conventional ventilation option for treating neonatal respiratory distress syndrome. The paper has been cited twice, according to Clarivate’s Web of Science.

University email addresses no longer effective bulwark against fake peer review

To guard against identity theft, academic publishers have been using institutional email addresses to verify authors and reviewers are who they say they are. Now, however, findings appearing in a preprint last month on arXiv.org suggest bad actors have found a way to breach this defense – and are routinely doing so.

From a pool of thousands of reviewer profiles set up as part of AI conferences in 2024 and 2025, staff at the nonprofit OpenReview, a platform connecting authors with reviewers, found 94 profiles involving fake identities. In all but two cases, the impostors had used “round-trip-verified” email addresses belonging to the domains of “reputed” universities, the authors write. (The remaining two used “.edu” domains of defunct institutions.)

Impersonating someone else using an institutional email address “adds another layer of challenge in the detection” of bad actors, said first author Nihar B. Shah of Carnegie Mellon University in Pittsburgh, who also sits on OpenReview’s board.

Exclusive: Iraqi physicist fired by ministry over massive publishing scam

A professor of physics in Iraq was permanently dismissed last week after a government investigation found he orchestrated a massive fraudulent publishing scheme involving hundreds of thousands of dollars paid into his bank account by unwitting researchers, documents obtained by Retraction Watch show.

The scam included a deal between a prominent association of Iraqi academics and a predatory publisher, as well as the creation of a fake journal website and bogus acceptance letters purporting to be from reputed journals.

According to a ministerial order dated September 9 and obtained by Retraction Watch, the physicist, Oday A. Al-Owaedi, who also goes by several other names, defrauded “researchers by collecting money from them under the pretext of publishing their papers in reputable international journals as promised, while in fact falsifying and forging publication in fake websites.”

Exclusive: Publisher investigating DNA contamination paper that authors say CDC vaccine committee will consider

The publisher Taylor & Francis is investigating concerns raised on PubPeer about a paper claiming to find DNA contamination in COVID-19 vaccines beyond regulators’ recommended amounts.

The move comes as the U.S. body tasked with making recommendations for vaccine use is scheduled to consider the safety of COVID-19 shots, and two of the study’s authors say their findings will be discussed.

The paper at issue was published September 6 in the journal Autoimmunity, a Taylor & Francis title. Scientific sleuth Kevin Patrick soon posted concerns on PubPeer, which he forwarded to the ethics department of the publisher.
