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?

Business management journal holds researcher’s paper hostage

A “scholarly business and management publication” is holding a researcher’s paper for ransom, requesting the author pay to withdraw the article.

The researcher submitted a manuscript in August to the Academy of Strategic Management Journal in August, thinking he had sent it to the Academy of Management Journal. He asked to remain anonymous for fear of seeming careless “rather than recognizing the real predatory nature” of the journal.

The journal’s homepage notes it is indexed in Scopus, but it was delisted in 2021, nor is it indexed in Clarivate’s Web of Science. Its most recent volume contains five single-author articles from nonexistent universities. None of the articles has a DOI or provides an email for the author.

Technobabble papers by professor and editor under scrutiny

After we reached out to Eren Öğüt, his profiles at Google Scholar, ORCID and Frontiers’ Loop all vanished.

The reviewer, a neuroscientist in Germany, was confused. The manuscript on her screen, describing efforts to model a thin layer of gray matter in the brain called the indusium griseum, seemed oddly devoid of gist. The figures in the single-authored article made little sense, the MATLAB functions provided were irrelevant, the discussion failed to engage with the results and felt more like a review of the literature.

And, the reviewer wondered, was the resolution of the publicly available MRI data the manuscript purported to analyze sufficient to visualize the delicate anatomical structure in the first place? She turned to a colleague who sat in the same office. An expert in analyzing brain images, he confirmed her suspicion: The resolution was too low. (Both researchers spoke to us on condition of anonymity.)

The reviewer suggested rejecting the manuscript, which had been submitted to Springer Nature’s Brain Topography. But in November, just a few weeks later, the colleague she had consulted received an invitation to review the same paper, this time for Scientific Reports. He accepted out of curiosity. A figure supposed to depict the indusium griseum but showing a simple sine wave baffled him. “You look at that and think, well, this is not looking like an anatomical structure,” he told us.

Nature retracts paper for data manipulation by Ph.D. student

Nature has retracted a paper after an investigation at a U.K. institution found the first author — then a doctoral student — manipulated data.

The paper, which looked at the sensitivity of lung cancers to immunotherapy, appeared in April 2023 and has been cited 192 times, according to Clarivate’s Web of Science.

The retraction notice published today states first author Kevin Ng was responsible for the manipulation in the paper, including manipulated data in several figures. At the time of the experiments, Ng was a Ph.D. student at the Francis Crick Institute in London under the supervision of co-corresponding author George Kassiotis.

Northwestern to pay $2.3 million for falsified research in NIH grants

Northwestern University Feinberg School of Medicine

A researcher accused of falsifying research in work funded by the National Institutes of Health has cost Northwestern University $2.3 million.

The university, based in Evanston, Ill., violated the Civil Monetary Penalties Law when a former researcher at the school falsified work funded by an NIH award, according to a November press release from the U.S. Department of Health & Human Services’ Office of Inspector General. The researcher and other investigators then referenced the falsified research in grant applications, reports and other submissions to NIH for two other awards, according to OIG. Together, the three grants totaled about $5 million, with $3.5 million tied to Northwestern.

The Civil Monetary Penalties law allows OIG to impose penalties against individuals and entities that engage in fraud and other improper conduct related to government grants. OIG learned of the researcher’s manipulation when Northwestern self-disclosed the conduct, the release said.

Sage journal retracts more than 40 papers over concerns with peer review, author contributions

Sage has retracted 45 papers from one of its journals for questionable authorship and peer review.

The publisher began an investigation into Clinical Hemorheology and Microcirculation last year to address citation concerns, a Sage spokesperson told Retraction Watch. The journal was one of 20 titles that lost their impact factors in Clarivate’s 2025 Journal Citation Reports for excessive self-citation and citation stacking.

Sage retracted the articles due to “concerns around the peer review process underlying these articles and author contributions to these articles, as well as the integrity of the research process,” according to the retraction notice, published November 23. The publisher detected “one or more” issues in each of the papers, including patterns of citation manipulation, indicators of third-party involvement and problems with peer review.

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.

Finance professor in Ireland loses 12 papers in journals he edited

Elsevier has pulled a dozen papers by a finance professor in Ireland who oversaw the review of the articles and made “the final decision” to publish them in three journals he edited, according to the retraction notices.

The professor, Brian M. Lucey of Trinity College Dublin, and his coauthors disagreed with the retractions, which came a few days before Christmas.

“I’m not disputing the fact that I made the final decision” to publish the articles, some of which have garnered hundreds of citations, Lucey told us in an interview. ”What I’m disputing is that that is not prima facie grounds” for retracting them.
