Journal investigating paper on heart device with registration number for wrong trial

The publisher of a European Heart Rhythm Association journal is investigating a paper that lists the incorrect registration number for a clinical study of a widely used but controversial heart implant.

The paper, published in EP Europace in May, described a prospective study of the Watchman FLX, from Boston Scientific, for a procedure called left atrial appendage occlusion (LAAO) in 400 people with abnormal heart rhythms. The authors concluded the device was “feasible, safe, and resource efficient, achieving high procedural success and low complication rates.”

Cardiologists have warned of caveats with the device and the LAAO procedure itself, mainly that early studies found LAAO caused a “significantly higher rate of a primary composite endpoint that included stroke, systemic embolism, cardiovascular/unexplained death, and major bleeding.” A study earlier this year found LAAO with a Watchman device increased rates of stroke and other complications when compared to oral medications.

Above and beyond: An editor wanted authors to know they’d been falsely cited

Like many college professors today, Sarah S. Richardson has seen AI-hallucinated citations in work submitted by her students. But she was surprised when an editor recently contacted her about a hallucinated citation involving her own work.

A March 31 email from the editor in chief of Disability Studies Quarterly explained Richardson was one of six scholars falsely cited in a journal article. The editor apologized for the error and alerted Richardson of the paper’s retraction.

“The editor took the extra step of informing all scholars who could have been harmed by the hallucinated citation[s] and did so in an exceptionally thoughtful and caring manner,” said Richardson, the Aramont Professor of the History of Science and Professor of Studies of Women, Gender, and Sexuality at Harvard University. “I suspect that most hallucinated citations are never discovered, let alone redressed by a retraction and outreach to those affected.”

Tennessee researcher heads to court amid claims of theft, forgery and revenge

In May 2025, Tennessee authorities were preparing to arrest a university math professor for allegedly soliciting university donations from his students and pocketing the money.

Investigative records paint the picture of a professor who took financial and personal advantage of his students for years – from manipulating them into paying him rent to making them clean up after his dog – and grew vengeful when they spoke out about his alleged crimes.

As state investigators closed in, the professor, Don Hong, tried to get revenge against a student who reported him by accusing her of research misconduct and telling a journal to retract a study she recently authored, according to an investigative report from the Tennessee Comptroller of the Treasury. When a grand jury indicted Hong on May 5, 2025, for theft and forgery, it tacked on a retaliation charge for his actions against the student.

Wiley investigating book chapter on biodiversity for fake references

While reading a chapter from a 2024 book on restoring biodiversity in post-industrial land earlier this month, an ecologist came across a reference to a study on rewilding she wanted to look up.

But the ecologist, who has asked to remain anonymous for fear of retaliation from the chapter authors, couldn’t find a record of the 2020 paper, purportedly published in Ambio by “Knijn et al.” She decided to check the other references. She told Retraction Watch she found at least eight that didn’t exist.

The ecologist flagged the issue to the book’s publisher, Wiley, on September 7 but told us she never heard back, aside from an automated response.

Elsevier journal retracts 100+ papers for authorship issues, editor conflicts of interest

Science of the Total Environment (STOTEN) has retracted 165 papers this year, most for “suspicious” changes in authorship or editorial conflicts of interest.

The retractions have come after STOTEN was delisted from Clarivate’s Web of Science in November after the index put it on hold due to concerns about article quality. The journal published over 10,000 articles in 2024; so far this year it has published fewer than 1,000.

The retractions, most of which were issued in August, applied to articles published from 2018 to 2025. At least 50 of the papers were handled by associate editors who had “an ongoing collaboration on a co-publication” or “an extensive record of collaboration” with the authors of the articles, according to the notices.

Misconduct case dropped against AI expert after claims of AI use in recent book

Sweden’s national committee on research misconduct has dismissed a case against an expert in the social ramifications of artificial intelligence following allegations her recent book contained hallucinated references and other signs of AI use.

The author, Virginia Dignum, a professor in responsible AI at Umeå University, denied references in her book The AI Paradox were fabricated and said she made “ordinary editing mistakes.”

Frank Drewes, head of the computing science department at Umeå University, told Retraction Watch the institution received a report containing the allegations from an anonymous individual on July 6 and referred the case to the National Board for Assessment of Research Misconduct (NPOF) in Uppsala, in accordance with Swedish regulation.

Here’s what was happening elsewhere (some of these items may be paywalled, metered access, or require free registration to read):

Paper mill studies get cited by clinical guidelines, policy docs and more, analysis finds

Studies produced by a suspected paper mill are frequently cited in patents, clinical guidelines and policy documents, according to a new analysis.

The work, posted on arXiv on August 31, examined the fate of nearly 2,000 academic papers with one common factor: At least one coauthor lists the Pharmakon Neuroscience Network (PNN) as an institutional affiliation.

But there’s one problem: the PNN is not a real network of scientists. Instead, it’s an authorship-for-sale scheme, as Retraction Watch reported in 2022.

Lancet union declares first-ever strike over staff wages

Union members at The Lancet and its affiliated journals will go on strike Sept. 22 for one day with further action planned for the following week, after pay negotiations with parent publisher Elsevier fell apart, The Lancet’s union announced today.

The strike is the first in The Lancet’s 200-year history. Elsevier was ordered to recognize the union, a chapter of the National Union of Journalists (NUJ), in September 2025, and their collective bargaining agreement was finalized in February. As part of the action the union, which represents 110 employees in various roles across several of The Lancet’s 30 journals, is also calling on members to refuse to work hours outside their contracted amount.

Negotiations on pay and support for workers began in March when the union asked for a 7.5% pay raise in the first year. According to an open letter from the union, workers’ pay had failed to keep up with inflation, leaving them “substantially worse off than they were five years ago despite their growing expertise and responsibilities.”
