The head of a nuclear physics institute in Kazakhstan now has 21 retractions to his name — most of them logged in the past year — following dozens of his papers being flagged on PubPeer for data reuse and images showing suspiciously similar patterns of background noise, suggesting manipulation.

Maxim Zdorovets, director of the Institute of Nuclear Physics in Astana, has written or coauthored 480 papers indexed on Scopus, and one analysis puts him as the third most cited researcher in Kazakhstan. His prolific publication record has been linked to Russian paper mills, though those claims are unverified. Zdorovets has defended his work in a series of online posts, arguing the imaging similarities come from technical issues and that his own analyses prove image manipulation did not occur. He did not respond to Retraction Watch’s request for comment. 

The latest retraction for Zdorovets came last month when Crystallography Reports retracted a study containing electron microscope images “highly similar” to those published a year earlier in a now-retracted paper in the Russian Journal of Electrochemistry by a similar group of authors. Both papers also included images that closely resemble ones Zdorovets and his colleagues presented at a nanomaterials conference in Ukraine in 2017. In each instance, the images were meant to be showing different materials.

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.

A review article concluding the weed killer Roundup “does not pose a health risk to humans” has been retracted eight years after documents released in a court case revealed employees of Monsanto, the company that developed the herbicide, wrote the article but were not named as coauthors. 

The safety of glyphosate, the active ingredient in Roundup, is hotly debated and currently under review at the U.S. Environmental Protection Agency. The International Agency for Research on Cancer, part of the World Health Organization, in 2015 declared glyphosate “possibly carcinogenic.” 

The now-retracted article appeared in Regulatory Toxicology and Pharmacology, an Elsevier title, in 2000. Gary Williams, then a pathologist at New York Medical College in Valhalla, Robert Kroes, a toxicologist at the University of Utrecht in the Netherlands, and Ian C. Munro, a toxicologist at Cantox Health Sciences International in Ontario, Canada, were listed as the authors. The paper has been cited 614 times, according to Clarivate’s Web of Science.

Authors retract Nature paper projecting high costs of climate change

The authors of a highly publicized study predicting climate change would cost $38 trillion a year by 2049 have retracted their paper following criticism of the data and methodology, including that the estimate is inflated. 

The economic commitment of climate change,” which appeared April 17, 2024, in Nature, looked at how changes in temperature and precipitation could affect economic growth. Forbes, the San Diego Union-Tribune and other outlets covered the paper, which has been accessed over 300,000 times. It has been cited 168 times, according to Clarivate’s Web of Science.

But after two commentaries published this August raised questions about the study’s data and methodology, the researchers revisited their findings. “The authors acknowledge that these changes are too substantial for a correction,” the retraction notice, published today, states.

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.”

Iraqi journal suspected of coercion, two others dropped from major citation databases

The influential citation database Scopus has delisted three journals from Iraq in a blow to recent government efforts to boost the standing of the country’s scholarly publications. One of the titles, which was included in Clarivate’s Web of Science, was dropped from that index as well.

Last month we reported on allegations that one of the delisted journals, the Medical Journal of Babylon, a publication of the University of Babylon in Hilla, was coercing authors to cite its articles. Citation manipulation is widespread in Iraq and elsewhere, but is considered a form of scientific misconduct.

“The Medical Journal of Babylon was flagged for re-evaluation at the end of September when we received concerns, and because we observed outlier publication performance,” said a spokesperson from Elsevier, which owns Scopus. The publisher marked the journal as delisted in its October update of indexed and delisted titles.

Meet the researcher aiming to halt use of ‘fundamentally flawed’ database linking IQ and nationality

Rebecca Sear

Rebecca Sear is on a mission to convince publishers to retract articles that use a database that purports to rank countries based on intelligence.

To maintain the integrity of scientific literature, the professor of psychology at Brunel University of London and her colleagues are writing to journals that are publishing papers that rely on the so-called National IQ database, which aims to rank countries based on intelligence. It has drawn criticism for the way the data were collected. Sear’s efforts have so far led to two retractions.

“There is absolutely no scientific merit whatsoever in the National IQ database,” Sear told Retraction Watch. “That means that any conclusions drawn from the database will be faulty and worthless.”

Exclusive: Reviewer recommended against publishing paper on DNA in COVID vaccines

Rolf Marschalek was on vacation when he saw a new paper had been published in the journal Autoimmunity. Marschalek, a biochemist at Goethe University Frankfurt in Germany, was “very upset,” he told Retraction Watch – because he’d peer-reviewed the manuscript and had recommended against publication. 

The authors of the paper claimed to find DNA in mRNA-based COVID-19 vaccines above regulators’ suggested amounts. The article appeared online September 6, and within weeks the publisher began an investigation into concerns about its content, as we reported previously.

In Marschalek’s initial review, which he provided to us, he detailed how Qubit fluorometry, one of the methods the authors used to measure the amount of DNA in the vaccine vials, was “not suited” for use when samples contain much higher amounts of RNA than DNA, as is the case with mRNA-based COVID-19 vaccines. He cited a paper he and colleagues had written about methods of quantifying amounts of RNA and DNA in mRNA vaccine vials, including Qubit.

COVID-19 paper by scientists at Harvard, Duke gets expression of concern for ‘unreliable’ data

A Science journal has issued an expression of concern over questions about the data in a paper reporting the discovery of an antibody that neutralized all COVID-19 variants in mice.

The article appeared in Science Immunology in August 2022 and has been cited 36 times, according to Clarivate’s Web of Science. The study lists 30 coauthors from Boston Children’s Hospital and Duke University. An article by Boston Children’s published at the time said the findings could “contribute to new vaccine strategies.” 

According to the expression of concern, published November 21, the authors informed the journal of “potential data reliability concerns” with two of the figures. The journal is in the process of determining an “appropriate course of action,” the notice continues.

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.
