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.

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.

Springer Nature book on machine learning is full of made-up citations

Would you pay $169 for an introductory ebook on machine learning with citations that appear to be made up?

If not, you might want to pass on purchasing Mastering Machine Learning: From Basics to Advanced, published by Springer Nature in April. 

Based on a tip from a reader, we checked 18 of the 46 citations in the book. Two-thirds of them either did not exist or had substantial errors. And three researchers cited in the book confirmed the works they supposedly authored were fake or the citation contained substantial errors.

A journal has retracted a 22-year-old-paper whose first author is the integrity officer for the Committee on Publication Ethics over concerns about image editing that “would not be acceptable by modern standards of figure presentation.”

The 2003 paper, “A recombinant H1 histone based system for efficient delivery of nucleic acids,” was published in Elsevier’s Journal of Biotechnology and has been cited 41 times, according to Clarivate’s Web of Science. 

Sleuth Sholto David, who goes by the name “Mycosphaerella arachidis” on PubPeer, raised concerns about the image in December 2023, pointing out a “[d]ark rectangle” that appeared to be “superimposed onto the image.”

Editors won’t retract talc and cancer article J&J says is false in court

A journal will not retract a paper linking use of talc-based baby powder to cancer, despite legal pressure from the pharmaceutical giant that made the product. 

A lawyer representing a unit of Johnson & Johnson in May asked editors of the Journal of Occupational and Environmental Medicine to retract a paper on cases of mesothelioma associated with cosmetic talc, following the court-ordered release of the identities of the people described in the article. 

The lawyer alleged many of the patients had other exposures to asbestos than cosmetic talc, rendering the article’s fundamental claims “false.”

Journal corrects nearly 100 papers after authors fail to disclose they are on the editorial board

Wiley has issued a mass correction at one of its journals after finding nearly 100 papers with undisclosed conflicts of interest related to submissions by board members and relationships between authors and journal editors.

An investigation found conflict of interest issues in 98 papers published from 2020 to 2025 in Geological Journal, although the issues may have gone on before then, sleuths suggest. Nearly a third of the papers shared a single co-author — an associate editor at the journal.

That editor’s contract was not renewed, we have learned.

According to the correction notice, issued in early May, the journal had not taken “measures to manage potential conflicts of interest between authors and editors” for 98 articles.

Springer Nature psycholinguistics journal retracts over a dozen articles for authorship, peer review issues

A journal has retracted 16 papers after a whistleblower flagged it for “irregularities” in peer review, among other concerns. 

The Journal of Psycholinguistic Research, a Springer Nature title, published the papers between 2021 and 2024. The articles covered research ranging from studies of the work of Haruki Murakami and Kazakh literature to English reading fluency and the teaching competence of parents of children with cochlear implants.

Thirteen of the 16 articles have been cited one to five times, according to Clarivate’s Web of Science; one article has been cited 19 times, the highest of the bunch.

When PubMed got it right, Elsevier got it wrong, and Retraction Watch helped clear it up

More than 20 years after publishing a letter saying a set of papers should be retracted — and PubMed marking them as such — the journal has finally retracted the articles, following a Retraction Watch inquiry.

Let’s back up.

In 1998, the journal Contraception published a supplement with six articles on Implanon, a subdermal contraceptive implant. The papers examined the implant’s pharmacodynamics and side effects. The next year, the journal published two clinical studies of the implant, one on its effectiveness as a contraceptive and the other on its effect on lipid metabolism

Those two studies took place at centers in Jakarta, Indonesia. Some of the study data published in the supplement also included patients at those centers.

Journal tells author it’s retracting three papers for concept that ‘violates’ law of thermodynamics

A physics journal has informed an embattled rocket scientist that it will retract three of his papers, citing concerns raised by the retraction of another of his papers last year. 

All three articles appear in Physics of Fluids, published by AIP Publishing, and describe a phenomenon called “Sanal flow choking.” As we reported last year, some scientists have denounced the concept as “absolute nonsense.” The researcher who coined the phrase is the lead author on all papers, V.R. Sanal Kumar, a professor of aerospace engineering at Amity University in New Delhi. 

The papers are:

Paper on “wokeness” and mental health retracted for political reasons, authors say

The authors of an article linking scores on a “wokeness” scale and mental health issues are  blaming political bias for the retraction of their paper in March following post-publication peer review. 

The article, “Do Conservatives Really Have an Advantage in Mental Health? An Examination of Measurement Invariance,” appeared in the Scandinavian Journal of Psychology last August. It has been cited twice, according to Clarivate’s Web of Science, one being the retraction notice. 

“Following publication of this article, concerns were raised by third parties about the conclusions drawn by the authors based on the data provided,” according to the March 26 notice. After investigating, the publisher and the journal “concluded that the article contains major errors involving methods, theory, and normatively biased language,” which “bring into doubt the conclusions drawn by the authors,” the notice stated. The authors disagreed with the decision.

In a blog post, one author, Emil Kirkegaard, called the journal’s action “my first politically motivated retraction.” Kirkegaard’s studies and writings are provocative, on topics including race and IQ.
