University dean’s attempt to correct a paper turns into a retraction

A dean at an Australian university sought to correct some of his papers. He received a retraction instead.

We wrote last year about Marcel Dinger, dean of science at the University of Sydney, who was a coauthor on five papers with multiple references that had been retracted. In May 2024, Alexander Magazinov, a scientific sleuth and software engineer based in Kazakhstan, had flagged the papers on PubPeer for “references of questionable reliability.” Magazinov credited the Problematic Paper Screener with helping him find them.

Dinger told us at the time he intended to work with editors to determine whether the five papers should be corrected or retracted.

Retraction for ‘unsound’ analysis was ‘disproportionate and discouraging,’ author says

Our list of retracted or withdrawn COVID-19 papers is up past 500.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.

Retraction for ‘unsound’ analysis was ‘disproportionate and discouraging,’ author says

The editors of Scientific Reports have retracted an article on burnout because the statistical analysis of its main finding was “unsound.” But the authors dispute the editors’ take on the statistics and claim a mistake in the paper triggered an unfair review.

For the paper, published in November, the authors measured concentrations of cortisol in hair samples from nearly 500 healthcare workers in Buenos Aires to study the effect of the COVID-19 pandemic on chronic stress and burnout. The analysis hinged on a statistical method called mediation analysis.

“Mediation analysis is a method to understand how one thing causes another by looking at what happens in between,” said lead author Federico Fortuna, of the Institute of Physiopathology and Clinical Biochemistry at the University of Buenos Aires. “In our study, we examined whether depersonalisation mediates the relationship between hair cortisol — a biological stress marker — and emotional exhaustion, a key psychological symptom of burnout.”

Do you need informed consent to study public posts on social media?

The retraction of a paper looking at posts in a Reddit subforum about mental illness has once again raised questions about informed consent in research using public data.

To study the experience of receiving a diagnosis of schizophrenia, a U.K.-based team of researchers collected posts from the Reddit subforum r/schizophrenia, which is dedicated to discussing the disorder. They analyzed and anonymized the data, and published their findings in June 2024 in Current Psychology, a Springer Nature journal.

The paper prompted backlash on X in the subsequent months, and in the Reddit community used for the study. People on the subreddit were concerned about the lack of consent, potential lack of anonymity, and the hypocrisy of discussing ethics in the paper while not seeking consent, a moderator of that subreddit who goes by the handle Empty_Insight told Retraction Watch.

When it comes to conflicts of interest, affiliations are apparently no smoking gun

Seven papers on various aspects of vaping and cigarettes published in Toxicology Reports listed each authors’ affiliation – the tobacco company Philip Morris International – when they originally appeared in the journal between 2019 and 2023. And all but one article disclosed the funding for the research originated from the company.

That apparently wasn’t enough for the journal.

Toxicology Reports has issued a correction to add those affiliations as a conflict of interest. The statements were “missing or incorrect” in the original papers, according to the correction notice, published in the June 2025 issue of Toxicology Reports. In addition to reiterating that the authors work for PMI, the correction also adds to the conflict of interest statements that the authors were funded by the company and used its products in the research.

Harvard researcher’s work faces scrutiny after private equity deal

Just as a Harvard lab brought in tens of millions of dollars in private equity funding to pursue new treatments for obesity, past research from its lead investigator has come under fresh scrutiny.

Last month, the lab of Gökhan Hotamışlıgil, a professor of genetics and metabolism at Harvard’s T.H. Chan School of Public Health, secured a $39 million dollar investment from İş Private Equity, an Istanbul-based firm. The partnership centers on FABP4, a protein associated with obesity and other metabolic conditions.

But over the past decades, two of Hotamışlıgil’s papers have been corrected for image duplications, and since the announcement, renewed scrutiny of Hotamışlıgil’s work appeared on PubPeer, including for issues with statistical analyses.

Viral paper on black plastic kitchen utensils earns second correction

The authors of a paper that went viral with attention-grabbing headlines urging people to throw out their black plastic kitchen tools have corrected the work for a second time.

But a letter accompanying the correction suggests the latest update still fails “to completely correct the math and methodological errors present in the study,” according to Mark Jones, an industrial chemist and consultant who has been following the case. “The errors are sufficient to warrant a restating of the abstract, sections of the paper and conclusions, if not a retraction.”

The paper, “From e-waste to living space: Flame retardants contaminating household items add to concern about plastic recycling,” originally appeared in Chemosphere in September. The study authors, from the advocacy group Toxic-Free Future and the Amsterdam Institute for Life and Environment at Vrije Universiteit Amsterdam, looked for the presence of flame retardants in certain household plastic items, including toys, food service trays and kitchen utensils.

Remembering Mario Biagioli, who articulated how scholarly metrics lead to fraud

Mario Biagioli, a distinguished professor of law and communication at the University of California, Los Angeles — and a pioneering thinker about how academic reward systems incentivize misconduct — passed away in May after a long illness. He was 69.

Among other intellectual interests, Biagioli wrote frequently about the (presumably) unintended consequences of using metrics such as citations to measure the quality and impact of published papers, and thereby the prestige of their authors and institutions.

“It is no longer enough for scientists to publish their work. The work must be seen to have an influential shelf life,” Biagioli wrote in Nature in 2016. “This drive for impact places the academic paper at the centre of a web of metrics — typically, where it is published and how many times it is cited — and a good score on these metrics becomes a goal that scientists and publishers are willing to cheat for.”

Chinese funding agency penalizes 25 researchers for misconduct

In its second batch of misconduct findings this year, the organization responsible for allocating basic research funding in China has called out 25 researchers for paper mill activity and plagiarism.

The National Natural Science Foundation of China, or NSFC, gives more than 20,000 grants annually in disciplines ranging from agriculture to cancer research. The NSFC publishes the reports periodically “in accordance with relevant regulations,” the first report, released in April, states. The organization awarded 31.9 billion yuan, or about US$4.5 billion, in project funds in 2023.

The NSFC published the results of its investigations on June 13. The reports listed 11 specific papers and 26 grant applications and approvals.
