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 His recent letter to Toxicology Reports — which includes reference blunders with an 80-year-old paper and outdated COPE guidelines — criticizes the retraction of a paper tying infant deaths to vaccines.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 Of the 1,181 retracted citations identified, just over half were added to Wikipedia before the paper was retracted; a fifth were added after retraction but without any reader warning; and just over a quarter explicitly noted the retraction.     

They also measured how long it took the Wikipedia community to correct citations added before the paper was retracted.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.

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 authorsThomas 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.

New system for flagging retracted papers finds scores of them in Cochrane reviews

Cochrane has implemented a new system for checking whether any of its thousands of published reviews include retracted studies in their analyses, the organization announced today. The effort already has turned up dozens of reviews that do and will now get closer scrutiny to ensure their results and recommendations hold up.

Cochrane publishes systematic reviews on health-related topics that evaluate the strength of evidence on particular treatments and interventions. Professional organizations and policymakers use the more than 9,500 reviews when developing recommendations. Recently a study of anesthesia clinical trials found a high rate of the studies with faked or flawed data, and another revealed that retracted studies included in systematic reviews — 17% of which were Cochrane reviews — had a large impact on clinical guidelines derived from them. 

Last year, Cochrane rolled out a feature in its database of reports of clinical trials, called CENTRAL, to flag retracted studies. The publisher pulls data on retracted papers from the Retraction Watch Database, via CrossRef. Now, they have extended the process to routinely identify systematic reviews that rely on retracted papers.

Court dismisses biochemist’s lawsuit against MD Anderson

A Texas court has dismissed a lawsuit by a biochemist accused of research misconduct who claimed her former institution violated her due process rights during its investigation. 

Sonia Melo sued The University of Texas MD Anderson Cancer Center in Houston in 2025, alleging the institution failed to follow its policies during a misconduct investigation into her work. MD Anderson found in May 2024 Melo had engaged in research misconduct while a postdoctoral fellow between 2012 and 2014, according to court documents.

Attorneys for MD Anderson requested a judge dismiss the suit in February, arguing the institution is a governmental entity entitled to sovereign immunity that protects it from lawsuits seeking money. Under Texas law, public hospitals are shielded from most suits by immunity rules. Some loopholes for medical negligence exist, such as when medical equipment harms patients.

Journal retracts paper criticizing parental alienation theory after group threatens to sue

A humanities journal has retracted an article about the controversial theory of parental alienation after receiving legal threats from a group that supports the concept. 

On May 19, the Integrated Journal for Research in Arts and Humanities (IJRAH) removed a review article by Robert Keith Head suggesting the theory of parental alienation is unsupported by research and fails “to meet basic validity requirements for psychological constructs.” 

The move came after the Parental Alienation Study Group (PASG) — which describes itself as an international, nonprofit membership organization dedicated to the study and understanding of parental alienation — accused the journal of publishing “scientific fraud” and demanded the journal retract the paper or face legal action. The journal said the removal was not dictated by “external demands or threats” but followed a “comprehensive secondary evaluation” by its editorial board and independent psychometric experts who identified “critical methodological and structural flaws that undermined the paper’s scientific validity.”

In what EIC calls an ‘honest mistake,’ journal approves paper without peer reviewing it

For most researchers, having an article accepted comes with constructive feedback from editors and reviewers. But when a sociology researcher learned his article was accepted at a Taylor & Francis journal, he was surprised to find the journal had skipped the peer review process altogether. 

Martino C. submitted his article on the effects of economic instability on political ideology in Slovakia to the journal Democracy and Security on October 15. (We’ve withheld the author’s last name at his request for digital privacy reasons.) He told Retraction Watch he was hoping peer reviews would help him improve his argument. 

But on January 13, the paper was marked “Accepted” in the journal’s submission portal without feedback.

Elsevier retracts study tying sudden infant death syndrome to vaccinations

Elsevier has retracted a 2021 study claiming sudden infant death syndrome is linked to vaccines over concerns the paper might influence patient care.  

The single-author study, by longtime vaccine critic Neil Z. Miller and published in Toxicology Reports, found 75 percent of SIDS cases reported occurred within seven days of vaccination, suggesting the fatalities are tied to immunizations. In an April 9 notice, Elsevier said it initiated an investigation into the paper after concerns arose from readers about potential research errors and methodological flaws.

According to the removal notice, editor-in-chief Lawrence H. Lash determined the author’s response did not “satisfactorily address” the concerns, particularly, the “serious methodological flaws” in using the Vaccine Adverse Event Reporting System (VAERS) to infer a correlation between vaccination and SIDS.

Critics of birdsong study fight to be named in Nature’s retraction

Researchers who flagged methodological issues in a paper on birdsong a year and a half before Nature retracted it say they should be credited in the editorial notice. But the editors have refused, with one telling the critics the paper was retracted for unrelated reasons.

The March 2024 study at the center of the dispute looked at how sexual selection may drive song patterns in male zebra finches. Nature retracted the paper last month because two of the synthetic song pairs used in the study were found to be unreliable, according to the notice. All three authors agreed to the retraction. 

Todd Roberts, the paper’s corresponding author, told Retraction Watch the critics now asking for credit “prompted us to check the synthetic song pairs used in our paper.” He said his team did not do the reliability analysis of the pairs until after publication.
