Diabetes association VP resigns over response to editorial boycott following protest at annual meeting

The top publishing executive at the American Diabetes Association has resigned over how the organization has handled an editorial boycott at one of its journals following a protest at its annual meeting earlier this year.

Christian Kohler, vice president for professional publications, submitted his resignation on Nov. 6, “after considerable reflection and with profound disappointment in ADA’s handling of the events of June 5 in New Orleans, its subsequent responses to and justifications for those events, and its continued failure to articulate a credible path toward resolving the resulting crisis of confidence within the diabetes research community.”

Kohler has been with ADA for more than 20 years, according to his LinkedIn profile, and in his current role since 2022.

U.S. university asks journal to remove professor’s name from paper with coauthor in China

A physics journal has removed a professor’s name from an article at his university’s request, because a coauthor works at a university in China that has been flagged for national security concerns.

“The decision of the journal has been of course to consult the author,” Carlo Rovelli, the editor of Foundations of Physics, a Springer Nature title, told Retraction Watch. “As for the author, it was a problem to challenge his own university.“

The professor, Emanuele Zappala, an applied mathematician at Idaho State University, was the senior author on a paper, “Operational Protocols Cannot Certify Classicality,” that had been accepted for publication. His name is still listed on a preprint posted online last year.

A year later, Springer Nature journal hasn’t updated article with fake reference to our cofounder

Some people might happily take credit for an article in Nature they did not write. That’s not the case when the credited author is a cofounder of Retraction Watch and the attribution comes in a citation to an article that doesn’t exist.

The reference appeared in a November 2025 paper, published in DARU Journal of Pharmaceutical Sciences, which criticized post-publication peer review platforms, specifically PubPeer, as vulnerable to “misuse” and “hyper-skepticism.”

Shortly after it was published, the article began to draw attention from users on — where else — PubPeer, where commenters flagged repetitive language, “essentially identical” paragraph structure, and five references that do not appear to exist, three with incorrect DOIs or links, and one with common authors that was retracted last year.

Bioengineered retracts 119 more papers as investigation continues

Bioengineered retracted 119 papers in October amid investigations into suspected paper mill activity and other integrity-related concerns at the Taylor & Francis journal.

Clarivate delisted Bioengineered from its Web of Science platform in May 2025, after placing it on hold a year earlier. In July 2025, the publisher suspended new submissions to the journal, which publishes bioengineering and biotechnology research, to focus on the investigations.

Concerns about paper mill activity date back to 2021, when the journal began investigating a spike in submissions and requests to change authorship after submission.

In the 2025 announcement, the publisher said it put an “under investigation” notice on over 1,000 articles.

Computing journal retracts 13 papers, including four from past EIC

An Elsevier journal on computer applications in biomedicine has retracted 13 papers — including four by a former editor-in-chief — for suspicious authorship changes and erroneous citations.

The articles were published in Computers in Biology and Medicine from 2019 to 2023. The October 15 retraction notices list suspicious changes in authorship, irrelevant citations to the work of authors and peer reviewers and self-plagiarism as reasons for retraction.

In 10 cases, the notice states, an “impartial field expert acting in the role of an independent Publishing Ethics advisor” requested the retraction.

Scientific Reports on hold in PubMed while NLM reevaluates journal

The National Library of Medicine has stopped indexing articles from Scientific Reports in MEDLINE because the journal’s inclusion in the world’s largest biomedical library is under review, Retraction Watch has learned.

“Following its significant growth in recent years, Scientific Reports is currently being reviewed by the US National Library of Medicine (NLM),” the journal’s chief editor Rafal Marszalek wrote in an Oct. 20 email we have seen. “We have been informed that during this period, indexing of newly published content in MEDLINE and archiving in PubMed Central (PMC) are paused, and will not appear in PubMed.”

Marszalek did not say why NLM is reviewing Scientific Reports, which is the largest journal in PubMed in terms of articles indexed. But according to MEDLINE’s policies page, NLM re-evaluates journals if “there are significant changes to a journal,” noting the library monitors journals “for changes in publication practices, such as annual publication volume or primary article content types.”

Springer Nature journal could lose registry standing for clearing author of duplication

A Springer Nature journal’s failure to find duplication in two papers by the same author could cost its official recognition as a scholarly publication in Norway.

The national register in Norway that decides which journals count toward academics’ publication records has concluded there is “no doubt” of duplication between two papers, which appear to use the same student survey. The ruling comes more than a year after Springer Nature, publisher of one of the journals, Innovative Higher Education, investigated the same issue and cleared the author.

Both papers were written by Artur Strzelecki of the University of Economics in Katowice, Poland, who denies there was any wrongdoing. Springer Nature told Retraction Watch it would consider the assessment from Norway, which it said was not available when the journal’s editors investigated.

Federal U.S. judge tosses $1 billion defamation lawsuit against Elsevier

A district judge has ended a $1 billion defamation case against Elsevier over a study about air purification technology after concluding the plaintiff’s evidence was too weak to take to trial.

Global Plasma Solutions, which makes air quality products, sued Elsevier in 2022 after the publisher declined to retract a paper in Building and Environment about the company’s needlepoint bipolar ionization technology. GPS claimed Elsevier was responsible for the authors’ alleged omission of data and misleading conclusions in the paper that led to “massive” financial losses for the company, according to its complaint. GPS, which now goes by GPS Air, claimed Elsevier knew the paper “failed peer review” but still published the paper.

On Oct. 22, the U.S. District Court for the Western District of North Carolina tossed out the suit. Judge Kenneth Bell wrote in his order there was “insufficient evidence” for a jury to conclude Elsevier acted with malice. “Actual malice” requires a plaintiff to prove the alleged defamatory statement was made with “knowledge that it was false or with reckless disregard,” which GPS could not support, according to Bell.
