NEJM retracts case study for AI-manipulated imagery

An “Images in Clinical Medicine” item in the New England Journal of Medicine has been retracted after the authors acknowledged using AI to alter the photo. Y. Wang, X. Mu/© The New England Journal of Medicine (2026).

The New England Journal of Medicine has retracted a clinical image with a picture the authors admit was manipulated with artificial intelligence.

The short piece, published April 18, reported the case of an 87-year-old man with lung damage after being exposed to a forest fire. The report included a startling image of black “casts” taken from the man’s airways, the size of which can be gauged by a tape measure at the top of the picture. 

The dramatic visual drew attention in the media (and one news outlet has already noted the retraction at the time of this writing). But the authors, Yuling Wang and Xiangdong Mu, of Daxing Teaching Hospital and Beijing Tsinghua Changgung Hospital, respectively, acknowledged having used AI to superimpose the tape ruler in the figure.

Are AI chatbots infiltrating online survey data? Not yet, says new study

Despite concerns some have raised about potentially compromised data, AI chatbots aren’t yet completing online research surveys widely, according to a new preprint. 

The authors of the study, posted earlier this month on PsyArXiv, found that fewer than 1% of around 4,800 survey responses collected by 12 different companies contained text that was likely not written by a human. Among 400 responses from a 13th company, however, around 16% were flagged for possibly being completed by a chatbot. 

The study used a novel detection tool created by the survey research company Prolific, which funded the project.

Researcher claims his case report was stolen by someone else at his hospital

A researcher claims a case report he coauthored was plagiarized by doctors at the same institution three years later — a paper he was alerted to when a journal sent it to him for review. 

Moayad Alqurashi, an infectious diseases specialist at King Fahad Armed Forces Hospital in Saudi Arabia, was the lead author on a 2021 case report published in Cureus about a patient who came to the emergency room with rapid vision loss. Doctors eventually diagnosed the patient with neurosyphilis, with non-arteritic anterior ischemic optic neuropathy, or NAION, as the presenting symptom. At the time, Alqurashi was a trainee at Prince Sultan Military Medical City in Riyadh.

Alqurashi told Retraction Watch that in 2023, while a reviewer for Skin Health and Disease, a Wiley title, he was invited to assess a report similar to the case he had written about. He said he notified the journal of similarities between the two cases, and the journal never published the report. The authors of that article had seen the same patient as part of a different department.

Black marks on published papers don’t change citation rates, new study finds

Among the data analyzed were mean monthly citations per article for 151 papers that were retracted or issued some other editorial notice, and for a set of control articles. The solid vertical lines are median time to the peak citation month, and the dashed line is median time to the editorial notice.
H. Studd et al/medRxiv 2026

Neither retractions, expressions of concern, nor other editorial notices seem to keep authors from continuing to cite problematic papers, according to a look at what happened to more than 170 articles by one author.

“After the public notification of integrity concerns about an article, it would be expected that other authors would no longer cite the article because it is unreliable,” write the authors of a new preprint. But that’s not what they found in a limited comparative study. Whether the study is generalizable has yet to be seen, says one other expert.

Four sleuths – the University of Aberdeen’s Hugo Studd and Alison Avenell and the University of Auckland’s Andrew Grey and Mark J. Bolland – charted citation data for 172 papers on clinical trials from Zatollah Asemi, a nutrition researcher at Kashan University of Medical Sciences in Iran, whose work has come under scrutiny.

Buying a first author slot can cost you anywhere from $56 to $5,600

The market for fake authorship on a research paper has prices to match every budget, according to a new dataset compiled from thousands of advertisements on social media platforms and paper mill websites. 

The dataset, called BuyTheBy, is the first systematic attempt to understand the market for paper mill products, according to its creators. It compiles more than 18,000 text-based advertisements from seven paper mills operating across India, Iraq, Uzbekistan, Latvia, Ukraine, Russia and Kazakhstan, collected at various points between March 2020 to April 2026. The researchers found prices vary widely depending on geography, ranging from $56 to $5,631 for a first author slot, according to a preprint submitted to arXiv. 

Several of the advertisements appear to correspond with published papers subsequently published in the targeted journals, with identical titles to those advertised. But cracking down on the industry with datasets such as these will be difficult, some experts say, especially as the business model evolves rapidly with AI.

Journal goes dark after impersonating Eric Topol and others

Within hours of researchers from prestigious institutions discovering they were listed as authors on a fabricated paper, the website for the journal and publisher has been taken down. 

Cardiologist Eric Topol, the executive vice president of Scripps Research, posted on X yesterday that his name appeared on a “fraudulent” paper published in the so-called Journal of Digital Health Implementation. He suspected the article, dated March 29 and titled “Implementation Science for AI Integration in Digital Health Systems,” was AI-generated. 

“If there ever was an AI-generated paper, this one would qualify as a high probability of being so,” Topol, who is also founder and director of the Scripps Research Translational Institute, told Retraction Watch.

Another retraction and two investigations for chemist

Maximilian Lackner

A chemist in Austria who earned a retraction earlier this year is under investigation by his former university, a national research integrity agency and the publisher Elsevier, Retraction Watch has learned, while scrutiny of his publication record has broadened to include more papers flagged on PubPeer. 

Maximilian Lackner, a technical chemist and process engineer at FH Technikum Wien in Austria until October last year, according to his ORCID profile, was the senior and corresponding author on a paper in npj Science of Food retracted in January after publishers discovered the five of the cited references weren’t relevant to the claims they were meant to be supporting. The 2024 article has been cited 90 times, according to Clarivate’s Web of Science.

Editors also pointed out the information in a flow diagram for selecting studies didn’t appear anywhere else in the article. One of the authors, Fatemeh Ahmadi of the University of Western Australia, told the journal she and Lackner disagreed with the retraction. When we asked why, Ahmadi said the authors were “not interested” in our request for further information.

A response to: Should universities investigate questionable papers students and faculty wrote elsewhere?

Editor’s note: We recently published a guest post on universities’ responsibility for investigating misconduct allegations related to work by staff and students conducted and/or published while they were at other institutions. The article prompted a vigorous discussion in the comment thread. Below is a letter to the editor from Itamar Ashkenazi and Howard Browman, both members of the Committee on Publication Ethics (COPE) Council.

Simon Kolstoe questions whether it is a university’s responsibility to act when concerns are raised about possible publication misconduct by their staff or students in situations where the misconduct relates to work conducted at other organizations.

We contend that it is their responsibility, regardless of where the work was conducted. That is because research and scholarly activity, while supported by universities, is conducted by people. It is the people who engaged in the misconduct who must be held accountable. That cannot happen without the participation of the institutions with which they had (and have) a formal relationship (as students, employees, contractors, etc.).

‘I asked him to stop’: Father adds daughter’s name to over 100 preprints without her permission

Anja/Pixabay

An author in China with nearly 500 preprints has continued to add his daughter’s name to papers – despite her insistence she was not involved. 

Shifa Liu, whose papers list affiliations with Peking University in China, has posted 499 works (and counting) on topics in physics and mathematics. His daughter, an undergraduate at an American university, is listed as a coauthor on over 100 of those preprints. In some cases, she was even named as the corresponding author. (Retraction Watch is not naming the daughter to respect her privacy and will not be accepting comments that name her.) 

The daughter told Retraction Watch she “did not participate in the research, writing, or submission of any of these papers,” adding her father included her name “without my knowledge or consent.”
