Papers continue to face retractions for failure to license pricy tool

Two journals have retracted papers this year for unauthorized use of a controversial scale whose creator has been known to license use of the questionnaire for six-figure sums – and to aggressively pursue those payments from researchers he claims have misused the instrument without prior approval.

The Morisky Medication Adherence Scale (MMAS) is named for its creator, Donald Morisky, now a professor emeritus in community health at UCLA. As the name implies, the measure allows researchers to assess patients’ adherence to drug regimens.

Morisky made a business out of licensing the scale and demanding steep fees for researchers who failed to obtain the proper permissions, as we reported in Science in 2017. Researchers who cannot afford the payments Morisky and his business associate demand have been forced to retract their work.

Embattled journal Cureus halts peer reviewer suggestions

The mega-journal Cureus is eliminating author suggestions for peer reviewers, a prompt that is standard practice at some journals when submitting a manuscript.

According to an email sent August 25 to current and past peer reviewers, the move is “due to the potential conflict of interest” that comes from authors suggesting reviewers who may be mentors and colleagues.

Reviewers recommended by authors are more likely to give positive feedback on papers. And such recommendations gave way to such practices as peer review rings and self-peer review, vulnerabilities that started to thrive more than a decade ago.

Top education researcher goes to court over plagiarism claims, university review

A prominent education researcher in Australia is demanding compensation from a critic whose claims of plagiarism triggered the university to look into his work. Although the resulting examination of work by John Hattie, director of an education research institute at the University of Melbourne, ended without a finding of misconduct, the critic, Stephen Vainker, insists Hattie’s publications are rife with data errors and insufficient attribution.

Vainker came across “strange” citations in a paper by Hattie while studying for his doctorate in education management seven years ago. At first, he found 12 sentences lifted word-for-word, he said, from the original source about workplace management without proper citation. Among them were seven instances in which words such as “people” or “individuals” were changed to education-related words, such as “students.”

Then Vainker looked through Hattie’s most popular and influential text, Visible Learning, and its sequel, as well as his doctoral thesis, finding what he claimed were hundreds of data errors and examples of plagiarism.

‘Tin Man Syndrome’ case plagiarized from hoax, sleuths say

*A comparison of the images and an overlay, provided by a sleuth.*

On April Fools’ Day 10 years ago, radiologist Matt Skalski took part in a website’s annual challenge to prank the radiology community by posting the case of a man with “ectopia cordis interna,” or “Tin Man Syndrome.” Unlike the fictitious metal character from the Wizard of Oz, Skalski’s satirical patient had a heart — in his abdomen.

Now a group of researchers say they encountered the disease in real life, in a 22-year-old patient they claim has “no significant medical history.”

The researchers based in Iraq published their “rare case report” in Medicine in July.

High school student who volunteered at NASA-sponsored lab gets retraction

An astronomical society journal has issued its first retraction in its 10-year history — for work done by a NASA researcher and a high school student. The duo set out to confirm an astrophysics law using calculations that assumed the law was true.

The journal, Research Notes of the AAS, is published by the American Astronomical Society. It is not peer-reviewed, nor is it indexed in Clarivate’s Web of Science. The retraction has prompted the journal to revise its policies on reviewing work before publication.

One of the two authors on the retracted 2024 article is Jadon Lam, who at the time was a student at Pleasant Grove High School in Elk Grove, California. Lam is now at the California Institute of Technology in Pasadena studying astrophysics, according to his LinkedIn profile.

Fighting coordinated publication fraud is like ‘emptying an overflowing bathtub with a spoon,’ study coauthor says

The observed and forecasted growth rate of paper mill papers outpaces corrective measures, a new study finds. *R. Richardson et al./PNAS 2025*

Systematic research fraud has outpaced corrective measures and will only keep accelerating, according to a study of problematic publishing practices and the networks that fuel them.

The study, published August 4 in Proceedings of the National Academy of Sciences, examined research fraud carried out by paper mills, brokers and predatory publishers. By producing low quality or fabricated research, selling authorship and publishing without adequate quality control and peer review, respectively, these three groups were well known to produce a large volume of fraudulent research.

“This is a great paper showing how much fraud there is in the scientific literature. The paper also looks at different methods on how to detect problematic papers, networks and editors,” Anna Abalkina, a researcher at Freie Universität Berlin and creator of the Retraction Watch Hijacked Journal Checker, said.

Microbiome company CEO who linked COVID vaccine to bacterial decline now has four retractions

A gastroenterologist and microbiome researcher who has promoted hydroxychloroquine and ivermectin as COVID treatments has lost a paper after a sleuth reported differences between the article and the registered protocol of the clinical trial it purported to describe.

The retracted article, on detecting SARS-CoV-2 in fecal samples, was published in Gut Pathogens in January 2021. It marks the fourth retraction for study coauthor Sabine Hazan.

Hazan is founder and CEO of ProgenaBiome, a laboratory in Ventura, Calif., advertising clinical trials exploring the role of the gut microbiome in conditions including autism and Alzheimer’s disease, as well as COVID. She is also CEO of Ventura Clinical Trials, which lists dozens of pharmaceutical and biotech companies among its clients.

Do men or women retract more often? A new study weighs in

When you look at retracted papers, you find more men than women among the authors. But more papers are authored by men than women overall. A recent study comparing retraction rates, not just absolute numbers, among first and corresponding authors confirms that men retract disproportionally more papers than women.

The paper, published May 20 in the Journal of Informetrics, is the first large-scale study using the ratio of men’s and women’s retraction rates, said study coauthor Er-Te Zheng, a data scientist at The University of Sheffield. The researchers also analyzed gender differences in retractions across scientific disciplines and countries.

Zheng and his colleagues examined papers from a database of over 25 million articles published from 2008 to 2023, about 22,000 of which were retracted. They collected the reasons for retraction from the Retraction Watch Database, and used several software tools to infer each author’s gender based on name and affiliated country.

Slovak science academy ‘strictly condemns’ government official’s paper on mRNA vaccines

Slovakia’s national science academy has issued a strong critique of a paper on mRNA vaccines coauthored by a member of the country’s parliament. The group called the work “insufficiently detailed” and “lacking controls,” with data that “may be misleading” and conclusions “not supported by sufficiently robust data.”

Peter Kotlár, the paper’s second author, is an orthopedist and represents the far-right Slovak National Party. He is also the commissioner for a review of resource management during the COVID-19 pandemic for the government of populist prime minister Robert Fico, himself known for questioning the science around COVID-19.

The paper appeared May 13 in the Journal of Angiology and Vascular Surgery, published by Herald Scholarly Open Access. “The journal in which the study of Peter Kotlár was published, is not evidenced in databases Web Of Science and Scopus,” a spokesperson for the Slovak Academy of Sciences, Monika Tináková, told us. The issues with the paper reflect “the fact that the journal in which it was published is classified as a so-called predatory journal,” the statement, issued last month, reads.

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.
