A dean at an Australian university sought to correct some of his papers. He received a retraction instead.
We wrote last year about Marcel Dinger, dean of science at the University of Sydney, who was a coauthor on five papers with multiple references that had been retracted. In May 2024, Alexander Magazinov, a scientific sleuth and software engineer based in Kazakhstan, had flagged the papers on PubPeer for “references of questionable reliability.” Magazinov credited the Problematic Paper Screener with helping him find them.
Dinger told us at the time he intended to work with editors to determine whether the five papers should be corrected or retracted.
In its second batch of misconduct findings this year, the organization responsible for allocating basic research funding in China has called out 25 researchers for paper mill activity and plagiarism.
The National Natural Science Foundation of China, or NSFC, gives more than 20,000 grants annually in disciplines ranging from agriculture to cancer research. The NSFC publishes the reports periodically “in accordance with relevant regulations,” the first report, released in April, states. The organization awarded 31.9 billion yuan, or about US$4.5 billion, in project funds in 2023.

A journal has retracted a 22-year-old-paper whose first author is the integrity officer for the Committee on Publication Ethics over concerns about image editing that “would not be acceptable by modern standards of figure presentation.”
Sleuth Sholto David, who goes by the name “Mycosphaerella arachidis” on PubPeer, raised concerns about the image in December 2023, pointing out a “[d]ark rectangle” that appeared to be “superimposed onto the image.”
A journal will not retract a paper linking use of talc-based baby powder to cancer, despite legal pressure from the pharmaceutical giant that made the product.
A lawyer representing a unit of Johnson & Johnson in May asked editors of the Journal of Occupational and Environmental Medicine to retract a paper on cases of mesothelioma associated with cosmetic talc, following the court-ordered release of the identities of the people described in the article.
The lawyer alleged many of the patients had other exposures to asbestos than cosmetic talc, rendering the article’s fundamental claims “false.”
Twenty journals lost their impact factors in this year’s Journal Citation Reports, released today, for excessive self-citation and citation stacking. Nearly half of the journals on the list are from well-known publishers MDPI, Sage, Springer, Taylor & Francis and Wiley.
Clarivate releases the annual Journal Citation Reports each June. For the first time, the company excluded citations to retracted papers when calculating this year’s impact factors. Amy Bourke-Waite, a communications director for Clarivate, told Retraction Watch this change affected 1% of journals, none of which lost impact factors in 2025.
Many institutions use the controversial metric as an indicator of journal quality. And suppressing a journal’s impact factor can have negative effects on the publication and the authors who publish papers in it.
One journal’s trash is another’s treasure – until a former peer reviewer stumbles across it and sounds an alarm.
In April, communications professor Jacqueline Ewart got a Google Scholar notification about a paper published in the World of Media she had reviewed, and recommended rejecting, for another journal several months earlier.
At the time, she recommended against publishing the article, “Monitoring the development of community radio: A comprehensive bibliometric analysis,” in the Journal of Radio and Audio Media, or JRAM, because she had concerns the article was written by AI. She also noticed several references, including one she supposedly wrote, were fake.
Driving those headlines was a December 2014 study in Science, by Michael J. LaCour, then a Ph.D. student at the University of California, Los Angeles, and Donald Green, a professor at Columbia University.
Researchers praised the “buzzy new study,” as Slate called it at the time, for its robust effects and impressive results. The key finding: A brief conversation with a gay door-to-door canvasser could change the mind of someone opposed to same-sex marriage.
By the time the study was published, David Broockman, then a graduate student at the University of California, Berkeley, had already seen LaCour’s results and was keen to pursue his own version of it. He and fellow graduate student Joshua Kalla had collaborated before and wanted to look more closely at the impact canvassing could have on elections. But as the pair deconstructed LaCour’s study to figure out how to replicate it, they hit several curious stumbling blocks. And when they got a hold of LaCour’s dataset, or replication package, they quickly realized the results weren’t adding up.
PLOS One has retracted a 2011 paper first flagged for image issues 11 years ago. The retraction marks the fourth for the paper’s lead author, Gabriella Marfè of the University of Campania “Luigi Vanvitelli,” in Caserta, Italy.
Elisabeth Bik flagged the article on PubPeer in 2014 for apparent image manipulation and duplication in six figures. In a 2019 email to PLOS staff, pseudonymous sleuth Claire Francis drew attention to Bik’s findings. The journal retracted the paper on May 6 of this year.
For years, sleuths – whose names our readers are likely familiar with – have been diligently flagging issues with the scientific literature. More than a dozen of these specialists have teamed up to create a set of guides to teach others their trade.
The Collection of Open Science Integrity Guides (COSIG) aims to make “post-publication peer review” more accessible, according to the preprint made available online today. The 25 guides so far range from general – “PubPeer commenting best practices” – to field-specific – like spotting issues with X-ray diffraction patterns.
Although 15 sleuths are named as contributors on the project, those we talked to emphasized the project should be largely credited to Reese Richardson, the author of the preprint.

President Trump recently issued an executive order calling for improvement in the reproducibility of scientific research and asking federal agencies to propose how they will make that happen. I imagine that the National Institutes of Health’s response will include replication studies, in which NIH would fund attempts to repeat published experiments from the ground up, to see if they generate consistent results.
Both Robert F. Kennedy Jr., the Secretary of Health and Human Services, and NIH director Jay Bhattacharya have already proposed such studies with the objective of determining which NIH-funded research findings are reliable. The goals are presumably to boost public trust in science, improve health-policy decision making, and prevent wasting additional funds on research that relies on unreliable findings.
As a former biomedical researcher, editor, and publisher, and a current consultant about image data integrity, I would argue that conducting systematic replication studies of pre-clinical research is neither an effective nor an efficient strategy to achieve the objective of identifying reliable research. Such studies would be an impractical use of NIH funds, especially in the face of extensive proposed budget cuts.
