Retraction Watch

How do retractions impact researchers’ career paths and collaborations?

About 46% of authors leave their publishing careers around the time of a retraction, a new study has found.
*SA Memon et al/Nat Hum Behav 2025*

Several studies have tackled the issue of what effect a retracted paper has on a scientist’s reputation and publication record. The answer is, by and large, it depends: The contribution the researcher made on the paper, their career stage, the field of study and the reason for the retraction all play a role.

Three researchers from New York University’s campus in Abu Dhabi wanted to better understand how a retraction affects a scientist’s career trajectory and future collaborations. Using the Retraction Watch Database, they looked at papers retracted between 1990 and 2015, and merged that data with Microsoft Academic Graph to generate information on researchers’ pre- and post-retraction publication patterns, as well as their collaboration networks. They also looked at Altmetric scores of retractions to factor in the attention a retraction got.

From that data, they extrapolated if and when researchers with retracted papers left scientific publishing, and looked for trends in researchers’ collaboration networks before and after the retraction.

Journal investigating placebo effect study following Retraction Watch inquiry

An Elsevier journal is investigating a paper by a controversial author after a Retraction Watch inquiry about the article. The article concluded that “placebo effects have a significant impact on observed outcomes” in both placebo and treatment groups in clinical trials.

The senior author of the paper is Harald Walach, whose name may be familiar. In one paper, now retracted, Walach and his coauthors claimed COVID-19 vaccines killed two people for every three deaths they prevented. In a different paper, also retracted, Walach and his colleagues claimed children’s masks trap carbon dioxide; they later republished the article in a different journal. He lost two papers and a university affiliation in 2021.

One of his latest papers, “Treatment effects in pharmacological clinical randomized controlled trials are mainly due to placebo,” appeared online December 27 in the Journal of Clinical Epidemiology.

Web of Science delists bioengineering journal in wake of paper mill cleanup

Bioengineered has lost its spot in Clarivate’s Web of Science index, as of its April update. The journal has been working to overcome a flood of paper mill activity, but sleuths have questioned why hundreds of papers with potentially manipulated images have still not been retracted.

A spokesperson for Taylor & Francis, which publishes the journal, said it has taken action against the paper mill; the journal has retracted 86 papers since January 2022. They are “disappointed” at the delisting decision, the spokesperson said. The journal now faces up to a two-year embargo before it can rejoin the citation index.

Bioengineered publishes bioengineering and biotechnology research. In 2021, journal editors launched an investigation when submissions spiked and several authors of submitted and accepted articles asked for authorship changes – both hallmarks of paper mill activity.

Journal collected $400,000 from papers it later retracted

A Sage journal that holds the distinction of highest number of retracted articles in the Retraction Watch Database likely made in excess of $400,000 in revenue from those papers, by our calculations.

We reported in April that the Journal of Intelligent and Fuzzy Systems (JIFS) had retracted 1,561 articles as part of a cleanup operation on likely paper mill activity. The journal, which Sage acquired in November 2023 when it bought IOS Press, had previously retracted a batch of 49 articles in October 2021. That brings its retraction total up to 1,610.

Commenters on the April article pointed out the journal charges a fee for all accepted papers; separate fees apply for open access. We followed up on that with a few questions for Sage.

‘Now is not the time to fade’: Retraction Watch awarded Council of Science Editors’ highest honor

Retraction Watch cofounders Adam Marcus and Ivan Oransky accept the award.

Retraction Watch has been honored with the Council of Science Editors’ highest honor: The 2025 Award for Meritorious Achievement.

CSE gives the award each year to an organization or individual who has made “significant contributions” toward the goal of CSE, “namely, the improvement of scientific communication through the pursuit of high standards in all activities connected with editing.”

We were honored to be at the CSE Annual Meeting in Minneapolis today to accept the award. Below is a lightly edited version of our acceptance speech.

A ‘stupid mistake’: EPA researcher added their underage child as an author on manuscript

A researcher at the Environmental Protection Agency added their underage child as a coauthor on a paper after the manuscript cleared the agency’s internal review, an investigation found.

The revelation, which calls into question the EPA’s process for reviewing papers, was among several highlighted by the agency’s Office of Inspector General in an April 8 report, which is redacted for names and identifying details.

The report cites specific concerns regarding the researcher, including that their child listed the paper among their accomplishments on college applications. These and other authorship practices revealed deeper issues with the review system at the EPA’s Office of Research and Development (ORD), which the report found “lacks oversight.” The OIG recommended the office take steps to address shortcomings, as the collaborations “remained unchecked” for “several years.”

Former cancer researcher who sued university for discrimination hits 35 retractions

A cancer researcher who was once the subject of a misconduct investigation at an Illinois university more than 10 years ago has made his debut on the Retraction Watch Leaderboard with 35 retractions.

Last month Oncogene, a Springer Nature title, retracted 15 articles by Jasti Rao, formerly of the University of Illinois College of Medicine at Peoria. A 2014 university investigation into his lab’s publications found manipulation and rotation of images that “‘show a disturbing pattern’ indicative that Rao acted intentionally or recklessly,” we previously reported. Rao sued the university for wrongful termination but lost.

More than 100 of Rao’s papers have comments on PubPeer, most originating from a user called Lotus azoricus. We now know that pseudonym belongs to sleuth Elisabeth Bik.

A Ph.D. in paper mills?

A university and a publisher are teaming up to combat paper mills in a unique way: By enlisting a Ph.D. candidate.

In April, the Centre for Science and Technology Studies (CWTS) at Leiden University in the Netherlands announced it would be collaborating with Wiley to establish a four-year research position focused on paper mills.

“Of course one Ph.D. will not fix the problem,” said Cyril Labbé of Grenoble Alpes University in France, whose lab hosted a Ph.D. student in 2014 to detect computer-generated manuscripts. “But going this way is far more constructive than resorting to empty rhetoric and wooden language, as some publishers tend to do.”
