Lancet flags long-scrutinized report of infant poisoned by opioids in breast milk

The Hospital for Sick Children in Toronto

The Lancet has put an expression of concern on a 2006 case report of a baby’s death purportedly from morphine poisoning through breast milk. The decision comes just days after the New Yorker published a year-long investigation into the death and the controversies that have surrounded it.

The case report described the 2005 death of a baby boy whose mother had been prescribed Tylenol 3, which contains codeine. Gideon Koren, founder of the now-defunct Motherisk Drug Testing Laboratory at the University of Toronto’s Hospital for Sick Children, used the case for years to claim codeine – which gets metabolized to morphine in the body – can pose a lethal risk to breastfeeding infants.

“It feels like an element of vindication,” David Juurlink, professor of medicine and pediatrics at the University of Toronto, told Retraction Watch of the expression of concern. Juurlink, a pharmacologist and toxicologist who has been pursuing this case for over a decade, requested The Lancet retract the article in 2020, when he and a colleague published a review article calling into question key elements of the case report. The paper, he said, “really does serve as the foundation of an entire branch of pediatric pharmacology that shouldn’t exist.”

Spanish court rules researcher plagiarized colleague, orders withdrawal of works

The Supreme Court of Spain has ordered a literary scholar to pursue retractions of nine works it determined were plagiarized.

The Tribunal Supremo upheld a lower court’s ruling that narrative theory researcher Franciscó Álamo Felices, a professor at the University of Almería in Spain, plagiarized a colleague’s work in two books and seven articles. José R. Valles Calatrava, a literary theory professor at the same university, sued Felices in 2019 for infringement of his intellectual property rights.

That lower court found Felices responsible for “a huge amount of plagiarism at different times and in different articles, revealing a systematic and conscientious parasitic attitude and a desire for appropriation,” according to a translation of the ruling by DeepL Translate. In an October 2025 decision, the Tribunal Supremo dismissed an appeal by Felices against the ruling, finding he failed to demonstrate any fundamental errors of law.

Lawsuit fails to block retraction of paper claiming to link heart-related deaths to COVID-19 vaccines

A Taylor & Francis journal has retracted a widely-read paper linking cardiac-related mortality to COVID-19 vaccines after an unsuccessful legal attempt by the lead author to block the withdrawal. That author says he is considering further legal action against the publisher.

The article, “Risk of all-cause and cardiac-related mortality after vaccination against COVID-19: A meta-analysis of self-controlled case series studies,” drew swift criticism when it was published in Human Vaccines & Immunotherapeutics in August 2023. At the time, critics and sleuths were quick to challenge the data and methods used in the paper, which now has more than 143,000 views on the Taylor & Francis website and has been cited 15 times, including by two letters to the editor of the journal and a response from the authors, according to Clarivate’s Web of Science.

The retraction notice, posted online January 16, states the retraction resulted from concerns that arose about the methodology of the study and the integrity and availability of the data. The authors provided a full response to the queries; however, the publisher determined the validity of the findings remained in question, the notice states. It continues:

Fed up, author issues her own retraction after journal ghosts her

At wit’s end after a publisher ignored her repeated requests for a correction, Ursula Bellut-Staeck took the extreme step of issuing her own retraction. But is that even a thing?

Bellut-Staeck, an independent researcher from Berlin, Germany, submitted a paper to SCIREA Journal of Clinical Medicine last spring after receiving an invitation from the journal. The article, about mechanotransduction and the impact of infrasound and vibrations, was published June 16.

But when Bellut-Staeck realized her affiliation as listed on the article needed changing, she contacted the journal to request a correction. The problem, she said, was linguistic. Because she didn’t realize “affiliation” has a different meaning in German than English, she had mistakenly listed herself as being at an institution she has since left.

Corrections, biases, and humility in science: Q&A with Tuan V. Nguyen

In a new memoir, Kangaroo Dreams, Tuan V. Nguyen, D.Sc., Ph.D., provides a unique perspective on medical research. Nguyen escaped Vietnam in 1981 as part of the mass “boat people” exodus of refugees, taking to dangerous waters just a few months after his older brother attempted the same and disappeared. Making his way to Australia through grit and luck in 1982, Nguyen started his new life as a dishwasher before steadily building a career in science, ultimately specializing in bone research.

Nguyen is now distinguished professor of predictive medicine and director of the Center for Health Technologies at the University of Technology Sydney and adjunct professor of epidemiology at the University of New South Wales. He’s also a Leadership Fellow of the Australian National Health and Medical Research Council and a member of the Order of Australia. Dedicated to the memory of his lost brother, Kangaroo Dreams weaves Nguyen’s personal journey with a thoughtful examination of contemporary medical research. We interviewed him in writing to learn more. (Responses have been lightly edited for length and clarity.)

Retraction Watch: You were co-author on a 1994 Nature paper subsequently corrected in 1997 which reported individuals with a particular vitamin D receptor gene benefitted from relatively high bone mineral density. When the research team made this finding, you write, “A nagging unease, however, bothered me. The results, while undeniably impressive, seemed almost too good to be true.” The team published the findings only to discover – after a Nature reader challenged the results – that a lab member who was ill likely contaminated samples, skewing the results. Did you regret not having pushed harder on your initial doubts? What held you back?

Professor suspended after Japanese university finds fishy results in sushi paper

A university in Japan has suspended a fishery science professor for a month after its investigation found fabrication in a retracted paper on fish freezing.

According to the investigatory report, Iwate University scrutinized a retracted paper coauthored by six researchers at the school, including Chunhong Yuan, a professor of fishery systems science. Following the researchers’ inability to provide the investigating committee with appropriate records of the reported experiment, the inquiry found Yuan and two unnamed coauthors – a graduate student and an individual now retired – fabricated claims about the experimental conditions.

Yuan has been suspended for one month starting December 25, according to a press release. The university plans to administer additional training on research integrity for laboratory leaders, according to the report.

Dogged by retractions, Iraqi researcher and publisher uses a different name

Researchers change the name they publish under for many reasons, most of which aren’t fodder for a Retraction Watch story. Trying to skirt a publishing ban is one that is. And another case that recently caught our attention may be in a similar category.

Researcher Abduladheem Turki Jalil is currently affiliated with the University of Thi-Qar in Nasiriyah, Iraq. His first published paper appears to be a survey on breast cancer from 2019. Jalil’s publications then took off, rising exponentially to more than 100 in 2022. According to Elsevier’s Scopus database, Jalil has an h-index of 44, and on his Instagram profile, he claims to be among the world’s top 2% scientists (he no longer is).

Jalil’s massive output has not failed to attract attention. In 2022, then-sleuth Nick Wise began flagging the researcher’s papers on PubPeer, providing screenshots of Facebook ads selling authorship of articles that matched several of Jalil’s publications. Wise also wrote a blog post about authorship-for-sale networks that mentioned Jalil and his extraordinary productivity.

Exclusive: In reversal, former vice chancellor in Pakistan who was let off hook for plagiarism faces sanctions

Three years after he was let off the hook by a government commission, a former university vice chancellor in Pakistan is facing sanctions for plagiarizing a student thesis in a paper from 2020, Retraction Watch has learned.

Muhammad Suleman Tahir, previously of Khwaja Fareed University of Engineering and Information Technology, is now professor and chair of the department of chemical engineering at the University of Gujrat. According to a report issued on November 20 by the Higher Education Commission (HEC) in Islamabad, Tahir and his coauthors have been barred from supervising graduate students for three years and also have received a warning for their offense.

Meanwhile, the University of Gujrat removed Tahir from his position as director of the institution’s Advanced Study & Research Board on December 3, according to a notification we obtained.

One of Kazakhstan’s top nuclear physicists also leads his nation in retractions

The head of a nuclear physics institute in Kazakhstan now has 21 retractions to his name — most of them logged in the past year — following dozens of his papers being flagged on PubPeer for data reuse and images showing suspiciously similar patterns of background noise, suggesting manipulation.

Maxim Zdorovets, director of the Institute of Nuclear Physics in Astana, has written or coauthored 480 papers indexed on Scopus, and one analysis puts him as the third most cited researcher in Kazakhstan. His prolific publication record has been linked to Russian paper mills, though those claims are unverified. Zdorovets has defended his work in a series of online posts, arguing the imaging similarities come from technical issues and that his own analyses prove image manipulation did not occur. He did not respond to Retraction Watch’s request for comment.

The latest retraction for Zdorovets came last month when Crystallography Reports retracted a study containing electron microscope images “highly similar” to those published a year earlier in a now-retracted paper in the Russian Journal of Electrochemistry by a similar group of authors. Both papers also included images that closely resemble ones Zdorovets and his colleagues presented at a nanomaterials conference in Ukraine in 2017. In each instance, the images were meant to be showing different materials.

Authors retract Nature paper projecting high costs of climate change

The authors of a highly publicized study predicting climate change would cost $38 trillion a year by 2049 have retracted their paper following criticism of the data and methodology, including that the estimate is inflated.

“The economic commitment of climate change,” which appeared April 17, 2024, in Nature, looked at how changes in temperature and precipitation could affect economic growth. Forbes, the San Diego Union-Tribune and other outlets covered the paper, which has been accessed over 300,000 times. It has been cited 168 times, according to Clarivate’s Web of Science.

But after two commentaries published this August raised questions about the study’s data and methodology, the researchers revisited their findings. “The authors acknowledge that these changes are too substantial for a correction,” the retraction notice, published today, states.
