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.

Another retraction and two investigations for chemist

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.

Embattled journal brand mistakenly invites out-of-scope researchers to join board

Springer Nature has launched a new agriculture journal under the troubled Cureus brand. As part of its launch, the publisher invited at least one researcher with irrelevant specialities to join its editorial board, Retraction Watch has learned.

The new journal comes after Clarivate’s Web of Science delisting the original and long-embattled Cureus Journal of Medical Science in October for concerns about article quality.

The flagship Cureus was founded in 2009 by John Adler Jr., a Stanford University neurosurgeon, as an open-access journal for clinicians who didn’t have grants. Springer Nature acquired the journal in December 2022. In 2024, the publisher launched Cureus Journals — open-access journals on engineering, computer science and business — using the brand name.

Librarian finds ‘preposterous number’ of fake references in paper from Springer Nature journal

As a hospital librarian, Jessica Waite is typically successful at tracking down elusive articles for clinicians at Royal Hallamshire Hospital in England. So when a colleague couldn’t locate two references in a paper and asked for help, the librarian grew suspicious.

“These were recent references, which usually we have no problem finding,” Waite told us. “I looked at the issues of the journals where the article should have been, and there were completely different articles, so I immediately thought that the articles we had been asked to find were not real.”

The references were from an article exploring mental health integration after bowel diversion surgery published in Digestive Diseases and Sciences (DDS), a Springer Nature title.

Medical journal publishes a letter on AI with a fake reference to itself

We’ve seen all kinds of articles that got published despite having references that don’t exist. But this was a new one: a paper with a made-up reference to the journal in which it appears.

While nonexistent references can indicate the use of a large language model in generating text, the authors maintain they used AI according to the journal’s guidelines.

The letter to the editor, published in December 2024 in Intensive Care Medicine, explored ways AI could help clinicians monitor blood circulation in patients in intensive care units. The 750-word letter included 15 references.

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.

Nature paper retracted after one investigation finds data errors, another finds no misconduct

Nature has retracted a paper on melanoma after an investigation by the journal found issues with data that rendered certain results statistically insignificant. A separate institutional investigation concluded misconduct wasn’t involved, the lead author says.

The research behind the article, published in April 2016, was conducted in the lab of Ashani Weeraratna, then at the Wistar Institute in Philadelphia. The paper has been cited 332 times, according to Clarivate’s Web of Science. The study investigated how the tumor microenvironment affected the spread of young versus aged cells.

An editorial investigation found some results in a figure were “no longer statistically significant, which affects the conclusions about therapy resistance,” according to the October 29 retraction notice. The inquiry also found “several errors in image and source data consistency,” as well as errors with the sample numbers given in the original study.

The case of the fake references in an ethics journal

Many would-be whistleblowers write to us about papers with nonexistent references, possibly hallucinated by artificial intelligence. One reader recently alerted us to fake references in … an ethics journal. In an article about whistleblowing.

The paper, published in April in the Journal of Academic Ethics, explored “the whistleblowing experiences of individuals with disabilities in Ethiopian public educational institutions.”

Erja Moore, an independent researcher based in Finland, came across the article while looking into a whistleblowing case in that country. “I started reading this article and found some interesting references that I decided to read as well,” Moore told Retraction Watch. “To my surprise, those articles didn’t exist.”

Springer Nature flags paper with fabricated reference to article (not) written by our cofounder

Update, Nov. 24, 2025, 5:48 p.m. UTC: This story was updated to add comment from Mohammad Abdollahi, the editor-in-chief of the journal and last author of the paper.

Tips we get about papers and books citing fake references have skyrocketed this year, tracking closely with the rise of ChatGPT and other generative large language models. One in particular hit close to home: A paper containing a reference to an article by our cofounder Ivan Oransky that he did not write.

The paper with the nonexistent reference, published November 13 in DARU Journal of Pharmaceutical Sciences, criticizes platforms for post-publication peer review — and PubPeer specifically — as being vulnerable to “misuse” and “hyper-skepticism.” Five of the paper’s 17 references do not appear to exist, three others have incorrect DOIs or links, and one has been retracted.

One of the fabricated references credits our cofounder Ivan Oransky with a nonexistent article, “A new kind of watchdog is shaking up research,” purportedly published in Nature in 2019.
