Journal retracts breast cancer paper 10 years after sleuth flagged issues

A biomedical journal has retracted a paper by a cancer researcher who sued her former institution over misconduct allegations. The action comes a decade after a sleuth first raised concerns about the article.

Former Ohio State researcher Flavia Pichiorri criticized how the publication, the Journal of Experimental Medicine, handled the dispute and said the journal suddenly pivoted away from its plan to republish the study with repeated experiments, a claim supported by correspondence seen by Retraction Watch.

In 2020, Ohio State University found Pichiorri, who worked in the lab of Carlo Croce, culpable for manipulating and reusing images in four publications, spanning from her time in Croce’s lab through establishing her own lab at Ohio State. Croce was cleared of direct misconduct, but OSU found serious management and oversight failures in his laboratory. Once a high-profile cancer researcher at Ohio State, Croce now has 18 retractions. He has filed several defamation lawsuits unsuccessfully, and reportedly owes his attorneys more than $1 million.

Publisher investigating peer reviewer for alleged bribery scheme

Earlier this year, Tushar Sen, an independent researcher based in New Delhi, submitted a manuscript to Security and Privacy about the modeling of polymorphic malware. On May 15, a purported reviewer for the journal wrote Sen indicating he received the article, but that it was not ready for publication.

“i may revise it with you but you should follow paid review for my efforts,” the email read. “i may finalise it in one week and i will recommend acceptance as a final decision.”

Sen, a cybersecurity researcher, believed the writer was attempting to extort money from him in exchange for recommending acceptance of his submission. He did not respond, but continued to receive more emails from the individual about the proposal. In a May 20 email, the person wrote they were “still awaiting” Sen’s response before “i submit rejection to the journal.” On May 23, the purported reviewer wrote, “I recommended the rejection decision” and “Gud (sic) luck.”

ORI sanction and news coverage prompts sleuthing, retraction

Four months after the Office of Research Integrity sanctioned a former postdoc for falsifying images in grant reports, a Science journal is retracting a paper by the researcher for image duplication.

After reading our story about the ORI’s findings, sleuth Paul S. Brookes took a look at the researcher’s ORCID profile and ran his papers through an AI tool that spots duplicate images.

Brookes’ analysis showed a 2019 paper in Science Signaling contained an image identical to an earlier study in Scientific Reports with the same first author — Chen-Yeh Ke, the former postdoctoral fellow at the Icahn School of Medicine at Mount Sinai in New York who was sanctioned by ORI in March for falsifying images in an unpublished manuscript supported by federal funds and reporting the fabricated results in two research performance progress reports.

Judge dismisses Splenda lawsuit, says courts wrong place for research debate

A North Carolina judge has scrapped a defamation suit by the maker of Splenda against a scientist, ruling the research dispute doesn’t belong in court.

TC Heartland LLC, which manufactures the artificial sweetener, sued researcher Susan Schiffman in 2023 alleging she made defamatory remarks to the public about the product following a study she authored about sucralose. The paper, published that same year in the Journal of Toxicology and Environmental Health, Part B, found “sucralose to be genotoxic” and called for a review of its regulation. A spokesperson for Taylor & Francis, which publishes the title, told Retraction Watch the article is under investigation.

The paper does not mention “Splenda,” but TC Heartland claimed Schiffman “relentlessly” disparaged the sweetener during media interviews to “promote” the paper and warned the public it was dangerous to consume, according to the company’s lawsuit. Schiffman, a professor in the department of electrical and computer engineering at North Carolina State University in Raleigh, countersued TC Heartland for defamation after the company created a webpage that challenged her research and “essentially accused her of being a publicity hound,” according to court documents.

Computer science society creates new research integrity role to address case backlog

Over the last five years, the Association for Computing Machinery has been dealing with a rapid rise in allegations of research misconduct that have created a backlog of cases to investigate.

The publisher has a committee to analyze claims, but with only a small group of volunteers, cases can take a year or more to resolve, said Scott Delman, ACM’s director of publications. To address allegations faster and with a sharper focus, the association is hiring a director of research integrity, a new role for the publisher.

“Certainly, we’ve been investing more financial resources in research integrity over the last five years, but we need an expert,” Delman told us. “We’re long past due in having a dedicated director of research integrity who will be the central resource for ACM on all things relating to integrity.”

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.

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.

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.”

Vietnam researchers face bans and funding cuts for violating integrity rules

Researchers in Vietnam who fabricate data or plagiarize papers may be permanently barred from future scientific work, according to new guidance from the country’s Ministry of Science and Technology.

The new framework, announced May 25, requires science and technology organizations to implement rules against research misconduct, and it outlines a process for investigating and sanctioning violations. The recommended penalties include written warnings, correction or retraction requests, public apologies, role suspensions, returning research funding, and bans from scientific projects. Violations of scientific integrity must also be recorded in the National Digital Platform for Science, Technology, and Innovation Management, according to the framework.

Researchers who use artificial intelligence inappropriately may also be subject to stiff sanctions. The framework warns researchers should not use AI to create fake data, images, or references nor unverified AI-generated material used as a reference.
