Despite new retractions, suspect organ transplant papers remain in the literature

Six years after researchers called for the retraction of more than 400 papers about organ transplantation amid suspicion the organs used in the studies came from executed Chinese prisoners, journals are still working to clear the record.

Although more than 40 papers were retracted or otherwise flagged shortly after the 2019 study was published, by our count, only 44 of the 445 papers have been retracted to date. At least 17 of the articles marked with expressions of concern in 2019-2020 remain as such.

The analysis, published in BMJ Open, found more than 400 studies of organ transplants in China that didn’t report whether the sources gave their consent for donation, nor assurances the organs involved did not come from executed prisoners. As reported by The Guardian in 2019, the study exposed “a mass failure of English language medical journals to comply with international ethical standards in place to ensure organ donors provide consent for transplantation.” Thirteen retractions this year directly cite the Rogers paper.

Controversial Paxil “Study 329” earns expression of concern after critic sues publisher

After more than 20 years of criticism and calls for retraction, a journal has placed an expression of concern on a study of the antidepressant Paxil in teens that critics say has led to unwarranted and potentially harmful prescribing of the drug to youth.

The 2001 paper, published in the Journal of the American Academy of Child & Adolescent Psychiatry (JAACAP), reported findings from a randomized trial known as “Study 329,” which concluded the antidepressant Paxil was safe and effective in kids ages 12 to 18.

In 2012, Paxil maker GlaxoSmithKline agreed to pay $3 billion to settle civil and criminal charges that included “unlawful promotion” of the drug for adolescents, for whom the product was never approved, and allegations the company “participated in preparing, publishing and distributing a misleading medical journal article” — the JAACAP paper. A reanalysis in 2015 found the drug was “ineffective and unsafe” for the age group studied.

Authors defend retracted paper on vitamin D and COVID-19 called ‘deeply bizarre’ by critic

PLOS One has retracted a paper linking vitamin D levels and COVID-19 morbidity three years after a critic flagged the data in the study as “deeply bizarre.” The authors objected to the retraction, with one calling it “outrageous” and pointing to flaws in the published notice.

The article, which appeared in February 2022, claimed people with low levels of vitamin D were at increased risk for severe COVID-19 and were more likely to die of the disease than other patients. It has been cited 65 times, according to Clarivate’s Web of Science.

The paper had a “huge, immediate impact,” said Gideon Meyerowitz-Katz, a senior research fellow from the University of Wollongong in Australia, citing the fact that the paper had been viewed over 1 million times within six weeks of being published. The article joins others, many also flagged by Meyerowitz-Katz, purporting to find links between vitamin D intake and COVID-19 severity that have been retracted or removed.

Math has publication fraud, too

Scholarly publishing in mathematics is unlike many other fields, marked by fewer papers, fewer coauthors per paper and fewer citations. But that doesn’t mean the field is immune to fraud and cheating.

A pair of papers posted to the arXiv addresses the issue of fraudulent publishing in math, particularly metrics gaming, and offers a list of recommendations to help detect and deal with that problem and other fraudulent activities. (The former was also published in the October AMS Notices; the latter will appear in the November issue.) “Fraudulent publishing undermines trust in science and scientific results and therefore fuels antiscience movements,” mathematician Ilka Agricola, lead author of both papers, told Retraction Watch.

A professor of mathematics at Marburg University in Germany, Agricola was president of the German Mathematical Society in 2021-2022 and is chair of the Committee on Publishing of the International Mathematical Union. The new articles are the products of a working group of the IMU and the International Council of Industrial and Applied Mathematics.

Study on apple cider vinegar for weight loss retracted after many raise concerns

Easy fixes for complex health problems can be tempting — but they rarely pan out. That seems to be the case for the investigators on one clinical trial who claimed consuming apple cider vinegar caused obese teens and young adults to lose weight.

Their article appeared in March 2024 in BMJ Nutrition, Prevention & Health. The journal is retracting the paper “because the authors’ analyses could not be replicated and multiple errors were identified,” according to the retraction notice.

The retraction, dated September 23, comes more than a year after sleuths pointed out some of these errors and other problems with the analysis.

University email addresses no longer effective bulwark against fake peer review

To guard against identity theft, academic publishers have been using institutional email addresses to verify authors and reviewers are who they say they are. Now, however, findings appearing in a preprint last month on arXiv.org suggest bad actors have found a way to breach this defense – and are routinely doing so.

From a pool of thousands of reviewer profiles set up as part of AI conferences in 2024 and 2025, staff at the nonprofit OpenReview, a platform connecting authors with reviewers, found 94 profiles involving fake identities. In all but two cases, the impostors had used “round-trip-verified” email addresses belonging to the domains of “reputed” universities, the authors write. (The remaining two used “.edu” domains of defunct institutions.)

Impersonating someone else using an institutional email address “adds another layer of challenge in the detection” of bad actors, said first author Nihar B. Shah of Carnegie Mellon University in Pittsburgh, who also sits on OpenReview’s board.

Exclusive: Publisher investigating DNA contamination paper that authors say CDC vaccine committee will consider

The publisher Taylor & Francis is investigating concerns raised on PubPeer about a paper claiming to find DNA contamination in COVID-19 vaccines beyond regulators’ recommended amounts.

The move comes as the U.S. body tasked with making recommendations for vaccine use is scheduled to consider the safety of COVID-19 shots, and two of the study’s authors say their findings will be discussed.

The paper at issue was published September 6 in the journal Autoimmunity, a Taylor & Francis title. Scientific sleuth Kevin Patrick soon posted concerns on PubPeer, which he forwarded to the ethics department of the publisher.

University vice chancellor’s work crawling with ‘tortured phrases’

The chief executive of a university in Eastern India whose research is full of tortured phrases – possible signs of plagiarism – had two papers pulled in December after investigations found evidence of “compromised” peer review and other red flags in the publications.

A third article by the executive, Amiya Kumar Rath, has also come under scrutiny, a publisher told us.

Rath became vice chancellor of Biju Patnaik University of Technology in Rourkela in 2023. A computer scientist with more than 100 publications, he is listed as the second author of one of the now-withdrawn works, a 2020 review article on inspecting and grading fruits using machine learning.

‘Article broker’ in China trying to hook journal editors with fishy publishing deals

Earlier this year, China’s supreme court said companies selling fake or low-quality research papers should be punished. But shady middlemen there continue to offer questionable deals to journal editors across the globe in a bid to secure publications for their customers, emails obtained by Retraction Watch suggest.

In the emails, sent between May and August and using the same boilerplate language, the Nanjing-based agency A-Techo said it would pay an “expedited processing fee” of $500 to $1,000 US “per accepted manuscript to support the review process.”

According to its website, the company provides various types of publication support. Signatures in the correspondence we obtained listed different names of purported assistant editors, who said they were “writing on behalf of an academic institution that supports Ph.D. researchers and faculty in publishing high-quality research.”

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.
