A prolific evolutionary biologist caught faking data decades ago notches a new retraction

A study claiming a tenfold decrease in bugs splattered on evolutionary biologist Anders Møller’s windshield over two decades has been retracted.

Anders Møller, an influential evolutionary biologist from Denmark, somehow survived the blow to his reputation after a high-profile retraction and a finding of scientific misconduct more than 20 years ago.

But a new retraction is once again raising the question of whether that fraud was just a blip in his impressive publication record or further proof, as some claim, that much of Møller’s work rests on a shaky foundation.

The latest paper to fall: Møller’s 2019 study in the journal Ecology and Evolution that reported a tenfold decline in the bugs splattered on his car windshield over two decades. The journal’s editors wrote in their retraction notice that the dataset contained “duplications” and “inconsistencies” that invalidate its conclusions.

Springer Nature to start issuing expressions of concern for books

Springer Nature will start issuing expressions of concern notices for books after investigating hundreds of its books for integrity-related problems in recent years.

The publishing giant has seen an uptick in the number of investigations for books. In 2022, Springer Nature carried out 124 such investigations. In 2023, that number grew to 207 in 2023 and 217 in 2024, Svetlana Kleiner, a research integrity adviser with the publisher, told attendees of the World Conference on Research Integrity in Vancouver, Canada, last month.

Springer Nature carried out 210 book-related probes last year, she added, and 81 in 2026 as of mid-April.

RFK Jr. has various stances on retractions. Critics say he’s ‘politicizing’ them

Robert F. Kennedy Jr.’s letter demanding answers from a journal that recently retracted an article about vaccines has drawn significant attention. But the inquiry isn’t the first time Kennedy has used his platform to try to influence retraction decisions, with one critic calling out a pattern by Kennedy of “politicizing” the process.

Scholars say Kennedy, the secretary of the U.S. Department of Health and Human Services, has shown an inconsistent ideological approach to retractions. Last year, he called for the retraction of a study that failed to find vaccines cause harm. His recent letter to Toxicology Reports — which includes reference blunders with an 80-year-old paper and outdated COPE guidelines — criticizes the retraction of a paper tying infant deaths to vaccines. While critics call his motives political, one researcher says a key component of Kennedy’s letter – a call for more publisher transparency – aligns with improving the retraction process.

In the June 11 letter to Lawrence H. Lash, editor-in-chief of Toxicology Reports, Kennedy demanded “a full explanation” from editors for removing a 2021 study linking sudden infant death syndrome to vaccines. We reported the retraction on May 26.

Some Wikipedia citations to retracted papers persist for years, study finds

Retracted scientific papers cited on Wikipedia tend to linger on the popular website for years, according to a study examining nearly 1,200 citations.

The study’s authors, led by Ph.D. candidate Haohan Shi from the Media, Technology, and Society Program at Northwestern University, used the Retraction Watch Database to compile a list of retracted papers and cross-referenced that list with Wikipedia citations. Of the 1,181 retracted citations identified, just over half were added to Wikipedia before the paper was retracted; a fifth were added after retraction but without any reader warning; and just over a quarter explicitly noted the retraction.

They also measured how long it took the Wikipedia community to correct citations added before the paper was retracted. The team found that while many corrections occurred swiftly, the median time for a correction was 3.68 years.

Journal investigating paper on cognitive impact of generative AI

A paper about the effects of generative AI use on confidence in work tasks is under investigation after critics raised questions about the study design, data analysis and ethics approval for the research.

The study, published in April in Technology, Mind, and Behavior, included 1,923 adults recruited online from the United States and Canada to perform a battery of work-like tasks assisted by AI. It garnered a press release from the American Psychological Association, which publishes the journal, and coverage in Time and Futurism.

Sandra Grinschgl of the University of Bern in Switzerland, who studies technology-driven cognitive offloading, got an alert about the study shortly after it came out. She told Retraction Watch she was initially puzzled by the vague descriptions of data collection from online participants in the study. When she looked closer at one of the bar charts, she noticed the lengths of the bars didn’t match the actual value of the labels.

Economist outs another Indian university’s rankings-boosting scheme when they refuse to pay him

On May 9, a university administrator in Afghanistan threatened in a LinkedIn post to expose what he called a publishing scam by private universities in India.

“These institutions contact academicians globally, promising payment for publishing research papers that will boost their national and international rankings,” Mohd Asif Shah, dean of the faculty of economics at Kardan University in Kabul, alleged.

The following day, Shah elaborated in a new post: “Four years ago, Woxsen University asked me to publish papers and file patents under their affiliation. I agreed, delivered, and they proudly displayed those publications on their website. Now, after four years, they are denying payment for that work.” He also complained his “patent incentives were being unilaterally reduced” from 40,000 Indian rupees (US$420) to 17,500 rupees (US$184) per patent — “a reduction of over 56%.”

Publisher investigating two more papers on glyphosate safety over ghostwriting claims

Tayor & Francis is investigating two papers about the weed killer Roundup following claims the articles were ghostwritten by the company that developed the herbicide.

The review comes after an Elsevier journal last year retracted a paper about Roundup linked to court documents that revealed company employees wrote the article but were not named as coauthors. Authors of the two latest papers under scrutiny stand by their work and deny any ghostwriting occurred.

Glyphosate, the active ingredient in Roundup, is highly contentious, with critics arguing the substance is carcinogenic and supporters contending the chemical is safe. The U.S. Supreme Court is currently weighing whether states can hold companies liable for failing to include cancer warnings on products containing the substance.

Science flags paper that found AI chatbots help debunk conspiracy theories

Science has issued an expression of concern for a highly publicized study looking into whether conversations with AI chatbots could convince conspiracy theorists to abandon their beliefs. The move came after the authors of the paper found inconsistencies in their dataset, but a reanalysis shows the findings still stand, they say.

The September 2024 article found conversing with an AI chatbot called DebunkBot reduced people’s belief in a particular conspiracy theory by an average of 20%. The research was featured in news stories in The New York Times, Washington Post and The Atlantic.

This February, the authors — Thomas Costello of Carnegie Mellon University in Pittsburgh, psychologist Gordon Pennycook of Cornell University in New York and cognitive scientist David Rand at the Massachusetts Institute of Technology — won the Newcomb Cleveland Prize from the American Association for the Advancement of Science, which publishes Science, for the work. It has been cited 192 times, according to Clarivate’s Web of Science.
