Osaka misconduct investigation leads to four retractions, with more likely

Research Institute for Microbial Diseases, Osaka University

A microbiologist formerly of Osaka University has lost four papers, with at least one more retraction pending, after an institutional investigation found fabrication and falsification of data in his published research. 

The investigation found evidence of manipulated results in seven of the papers examined. The university published the notice of its completed inquiry, along with a full report in Japanese, on February 6. 

The report did not name the scientists or cite the articles investigated, but it did include a figure or table with altered data from each paper. Three papers retracted in February mentioned an investigation by Osaka University in the notices; Yukihiro Hiramatsu was the first author on all three. Comparing the figures in the report with ones in Hiramatsu’s publications, we identified the seven articles. (See the list here.)

Guest post: Should Zimbardo’s Stanford Prison Experiment be retracted?

A prisoner and guard in the Stanford Prison Experiment. | PrisonExp.org

Philip G. Zimbardo passed away in October 2024 at age 91. He enjoyed an illustrious career at Stanford University, where he taught for 50 years. He accrued a long list of accolades, but his singular and enduring contribution to scholarship was the Stanford Prison Experiment, a simulation carried out in the university’s psychology department in August 1971. The research project became the best-known psychological analysis of institutionalization at the time. 

The study has always been treated with skepticism by penologists and psychologists, and recent scholarship by social scientist Thibault Le Texier has raised fundamental questions about the scientific validity of the investigation, the originality of the research design, the unethical treatment of the subjects, and the credibility of the reported results. 

Many consider Zimbardo’s SPE to be one of the classic studies of experimental psychology in the post-war period. It continues to be reported as a landmark achievement in many psychological textbooks today, despite drawing decades of criticism both in and out of the scientific literature. But considering Le Texier’s findings, should Zimbardo’s work be retracted?

Don’t tread on me: Snake paper retracted for ‘soft-stepping’ technique

Agitating snakes isn’t something most of us would do on purpose, but for a group of researchers, it was central to their research. The authors of a May 2024 paper in Scientific Reports achieved that by “softly” stepping on the head, tail and mid-body of newborn, juvenile and adult pit vipers to see how often they would bite. 

But the technique wasn’t quite what the authors’ ethics committee had in mind when approving the study. The journal retracted the paper last month, noting the ethics approval the authors received “did not include newborn snakes or the use of the ‘soft stepping’ method.” 

Lead author João Miguel Alves-Nunes blamed the retraction on a “communication error” by the ethics committee. The researchers believed they had approval both to step on snakes and to include newborn snakes, Alves-Nunes, a former researcher at the Butantan Institute in São Paulo, Brazil, said in an email to Retraction Watch.

His manuscript was rejected. Then he saw it published by other authors

A chemist at a university in Pakistan found a surprise when he opened an alert from ResearchGate on a newly published paper on a topic related to his own work. 

When Muhammad Kashif, a chemist at Abdul Wali Khan University Mardan, looked at the paper, he noticed “substantial overlap” with an unpublished review article he had submitted to other journals. On closer inspection, he found it was indeed his paper — published by other authors. 

“I was shocked and deeply concerned,” Kashif told Retraction Watch. “My unpublished work was replicated without attribution, undermining months of effort.”

Seven years after ‘noncompliance’ finding, whistleblowers push for retractions

VA San Diego

Seven years after investigations uncovered “serious noncompliance” in the collection of biological samples at a California VA hospital, the original whistleblowers say several papers related to the work use these problematic samples and should be retracted. But the principal investigator of the work says there’s no reason to question the findings.

The VA San Diego Health Care System was one of 12 institutions involved in the InTeam Consortium, a research initiative between 2013 and 2019 focused on alcohol-related liver inflammation. In 2016, two whistleblowers — Mario Chojkier and Martina Buck — alleged staff at the VA hadn’t obtained proper consent to perform biopsies on critically ill patients and use the samples for research related to the project. 

Subsequent investigations — including one by VA San Diego’s institutional review board — have confirmed violations of policies, primarily related to a lack of informed consent. Ramon Bataller, the principal investigator of the InTeam Consortium, told local media outlet inewsource in 2019 the samples collected at the VA would be “banished” from any academic papers.

Was nonsense ‘vegetative electron microscopy’ phrase a Farsi typo?

A gibberish phrase that caught the attention of science sleuths after it slipped into several journals might trace its origin to a typo in Farsi rather than questionable use of AI, as we reported earlier this month.

Nearly two dozen scientific papers, including some in journals from major publishers, mysteriously refer to “vegetative electron microscopy” or “vegetative electron microscope.” As we wrote in our previous story, sleuth Alexander Magazinov speculated on PubPeer “the phrase could have originated through faulty digital processing of a two-column article from 1959 in which the word ‘vegetative’ appeared in the left column directly opposite ‘electron microscopy’ in the right.”

Most of the articles containing the strange wording included authors from Iran. Magazinov told us perhaps an AI model had picked up the phrase from the 1959 article and spit it back into machine-generated text that was later plagiarized in other papers by the same Iranian network of fraudsters.

ICYMI: Dean under investigation for plagiarism following Retraction Watch story: report 

A university dean is being investigated for plagiarism following our coverage of accusations against him, a Bulgarian newspaper reported last month.

The Academic Ethics Commission in Bulgaria has launched an investigation into Milen Zamfirov, dean of the faculty of educational sciences at Sofia University, Dnevnik reported February 25. 

The accusations concern a 2021 paper he wrote with his colleague Margarita Bakracheva, “In Search of Integrativity of Sciences: the Principle of Supplementarity in the Story of Pauli and Jung.” As we reported in December 2024, the paper “seems to have significant overlap” with other sources.

Five studies from “Bust Size and Hitchhiking” author retracted 

A journal has retracted five papers about the appearance, sexual behavior and attractiveness of women. 

Nicolas Guéguen, a professor of marketing at the Université de Bretagne-Sud in France, was an author on each of the papers, published in the Sage journal Perceptual and Motor Skills (PMS) at least 15 years ago. All of the articles garnered expressions of concern in 2023, but Guéguen’s history of misconduct long precedes the PMS papers. 

Sleuths have been flagging Guéguen’s work for years for seemingly impossible results. In 2019, he was cleared of wrongdoing by his university, but since then has racked up at least four retractions, according to the Retraction Watch database.
