Springer Nature journal could lose registry standing for clearing author of duplication

A Springer Nature journal’s failure to find duplication in two papers by the same author could cost its official recognition as a scholarly publication in Norway.

The national register in Norway that decides which journals count toward academics’ publication records has concluded there is “no doubt” of duplication between two papers, which appear to use the same student survey. The ruling comes more than a year after Springer Nature, publisher of one of the journals, Innovative Higher Education, investigated the same issue and cleared the author.

Both papers were written by Artur Strzelecki of the University of Economics in Katowice, Poland, who denies there was any wrongdoing. Springer Nature told Retraction Watch it would consider the assessment from Norway, which it said was not available when the journal’s editors investigated.

Another Sydney investigation of astrophysicist leads to retractions

A 2014 paper has been retracted following an investigation that concluded several of the figures, including those shown here, were “likely fabricated.”

The University of Sydney has once again investigated the work of a former research fellow in its physics department, this time resulting in the retraction of two papers over concerns that data in several figures were likely fabricated.

In September, the Journal of Geophysical Research: Space Physics retracted two articles by Joachim Schmidt, who was at the University of Sydney from 2010 to 2021.

As Retraction Watch reported in 2023, the university previously investigated work from Schmidt and his supervising professor, Iver Cairns. Researchers at the University of Michigan had raised concerns about a figure in a draft manuscript supposedly created using a simulation model developed by the Michigan team. Sydney’s investigation found Schmidt had used Adobe Photoshop to create or alter the images, which could not be reproduced by digital forensic experts or by Schimdt himself.

Misconduct case dropped against AI expert after claims of AI use in recent book

Sweden’s national committee on research misconduct has dismissed a case against an expert in the social ramifications of artificial intelligence following allegations her recent book contained hallucinated references and other signs of AI use.

The author, Virginia Dignum, a professor in responsible AI at Umeå University, denied references in her book The AI Paradox were fabricated and said she made “ordinary editing mistakes.”

Frank Drewes, head of the computing science department at Umeå University, told Retraction Watch the institution received a report containing the allegations from an anonymous individual on July 6 and referred the case to the National Board for Assessment of Research Misconduct (NPOF) in Uppsala, in accordance with Swedish regulation.

PeerJ retracts study that secretly observed tourists’ reactions to snakes

For a study published in PeerJ, a researcher placed plastic snakes (left panel) and viper carcasses on hiking paths (right) to gauge people’s reactions. The journal retracted the paper in August for ethics approval concerns.
*A.V. Dyugmedzhiev/PeerJ 2026*

The journal PeerJ has retracted a study that attempted to capture tourists’ “authentic responses” to venomous snakes by putting plastic models and dead vipers around popular hiking destinations and secretly watching how people reacted to the encounters.

Study author Angel Valentinov Dyugmedzhiev of the Bulgarian Academy of Sciences assessed their reactions from a few meters away and never interacted with any of the participants so as to avoid “direct interference in the experimental setup,” he wrote in the paper, published June 23.

When tourists discussed the snakes among themselves, he recorded whether they correctly identified the species and whether they realized the viper was either dead or a model. The study found most tourists didn’t spot the vipers, and only a small number of them showed strong fear toward them.

Researchers appeal misconduct finding over studies of trans youth

Five researchers at Norway’s national gender incongruence clinic are appealing a university committee’s finding they committed “gross negligence” and scientific misconduct after the group published several studies using the medical records of more than 1,000 minors without patient consent.

Two of the articles set out to count how many minors were referred to the clinic, characterize the mental health burden of trans patients and document their treatment trajectories and detransition rates. In June, a joint committee of the University of Oslo and Oslo University Hospital (OUS) ruled five of the coauthors committed scientific misconduct for using the patients’ medical records without ethics approval or patient consent. The researchers maintain the work was for quality assurance, which in Norway doesn’t require consent. The committee ruled the work was research.

Two other articles violated research ethics standards in a “reprehensible” way, the committee found, but did not constitute misconduct. Those papers describe the outcomes of chest wall contouring and genital surgery.

Japan institute defends Nobel Prize winner amid allegations of image duplication

The Center for iPS Cell Research and Application (CiRA) at Kyoto University in Japan is defending Nobel Prize winner Shinya Yamanaka against claims of image manipulation in multiple studies on which he was an author. The institute says questioning Yamanaka’s integrity without sufficient evidence is “completely unacceptable.”

Yamanaka shared the Nobel Prize in Physiology or Medicine in 2012 and works at CiRA.

On August 7, Gotham City Research LLC, a short-selling firm based in the United States, released a report alleging image manipulation in several papers by Yamanaka appearing between 2000 and 2020.

A New Zealand journal deleted a paper for potential harm to Māori months after publishing it

When Arna Mitchell submitted her article critiquing a proposal for different standards of practice for Māori and non-Māori clients in clinical psychology, she thought it would be too controversial to publish because it challenged views becoming influential among professional and academic circles.

But the Journal of the New Zealand College of Clinical Psychologists (JNZCCP) had the paper peer-reviewed and published it in August 2025. And then, 10 months later, they deleted the article, after deciding the work could perpetuate harm to Māori, the indigenous people of New Zealand, and that it conflicted with the college’s values.

The college defended the deletion by arguing the journal is not an independent, indexed academic journal. But the decision has caused members to quit the college and has drawn criticism from the field, including from a former editor of the journal.

High-profile anesthesiologists earning retractions for data, image problems

In July 2021, John Loadsman received a manuscript about a clinical trial that immediately roused his suspicion. Then the editor-in-chief of Anaesthesia and Intensive Care, Loadsman asked the authors for the raw data.

They weren’t pretty. “When I looked carefully at the spreadsheet, I could see entire blocks of data that were repeated,” recalled Loadsman, an anesthesiologist and scientific sleuth at the University of Sydney. “It was obvious that this was cooked.”

He rejected the manuscript, informing both the corresponding author, Reyhan Polat of the University of Health Sciences in Ankara and Etlik City Hospital, in Turkey, and her institution about his concerns. He also made a mental note to have a look at the researcher’s published work. Over the following years, that effort drew in another sleuth and eventually prompted inquiries into more than two dozen papers by a network of researchers in Turkey.

Retraction Watch story exposing research factory fuels investigations, preprint withdrawals, termination

Raghabendra Kumar Mahato

A preprint server has withdrawn three papers by an author at the center of a Retraction Watch story revealing a prolific research factory operated through the WhatsApp messaging system.

Last week, we reported on Raghabendra Kumar Mahato, a second-year medical student in Nepal, who runs an international research network that churns out conference abstracts and journal papers at a rapid-fire pace. Mahato’s network includes nearly 1,000 members connected through WhatsApp and produces suspected fast-churn science, while recruiting authorship for the works. Papers by the network have been accepted by major journals and presented at conferences by leading medical societies.

On July 24, Research Square, a preprint server owned by Springer Nature, withdrew three manuscripts by Mahato due to concerns “regarding integrity arising from the submitting author’s involvement in a paper mill network,” according to notices placed on the work. The notices include a link to Retraction Watch’s investigation.

Kaggle removes problematic stroke dataset for copyright infringement

Images from the now-deleted dataset on Kaggle purportedly showed people who had a stroke, but the folder included stock images and photos of politicians and celebrities, as seen in this screenshot.

The online data repository Kaggle has removed a problematic dataset for violating intellectual property rights months after it was flagged by sleuths for containing celebrity photos and lacking information on data provenance or confirmed medical diagnoses.

Researchers had used the images to train machine learning algorithms to detect stroke, but the dataset instead contained images of people with Bell’s palsy — as well as pictures of celebrities from movies and on the red carpet, as we reported in May. Adrian Barnett, a medical statistician at Queensland University of Technology in Australia, flagged the dataset after discovering two others he and his colleagues investigated in a February preprint that showed signs of being fabricated.

Using a reverse image search, Barnett matched four of the photos in the dataset, called “Facial droop and facial paralysis image,” to a paper published years earlier in the Journal of the Canadian Dental Association (JCDA). Only after prompting the journal to complain to Kaggle did the company take down the dataset.
