Feud between physicists ends in defamation verdict

A prolonged feud between two physicists in Italy that has played out for years in journal letters and blog posts has resulted in a defamation award for one of the rivals.

Lorenzo Iorio and Ignazio Ciufolini have sparred for more than 20 years over claims of plagiarism, sock puppetry and defamation. After two criminal lawsuits against Iorio failed, Ciufolini took the spat to civil court where the Court of Rieti on April 15 ordered Iorio to pay Ciufolini €15,000 (roughly US$17,500) for defaming Ciufolini in blogs and online journals.

In her eight-page decision, Honorary Judge Francesca Tosi said the statements Iorio made about Ciufolini, which date back to 2011, were more than “mere criticism” justifying a difference of opinion.

Swiss court clears sleuth in defamation case, awards him legal costs

An appeals court in Switzerland has overturned a 2025 defamation conviction against a sleuth who had identified dozens of conference proceedings with signs of citation manipulation. The ruling orders the plaintiff to pay the sleuth’s legal expenses.

The judgment clears Solal Pirelli, a software engineer in Lausanne, in a lawsuit filed against him in 2023 by Shadi Aljawarneh, a computer scientist at the Jordan University of Science and Technology.

The case stemmed from a blog post Pirelli published in January 2023 summarizing problems with the proceedings of conferences organized under the auspices of the Association for Computing Machinery (ACM). Aljawarneh was the chair of most of the conferences, and the proceedings included signs of citation stuffing in Aljawarneh’s favor.

ORI announces 15-year debarment against former Rice University scientist

The U.S Office of Research Integrity has formally announced a 15-year funding debarment against a former Rice University scientist for research misconduct, resolving allegations that arose 17 years ago.

Chemist Ariel Fernández intentionally fabricated data in 12 grant-supported papers, four unpublished manuscripts, one presentation and three grant applications while a professor at Rice University in Houston, according to a notice posted May 1 on ORI’s website and to be published in the Federal Register on May 5. As part of the sanctions, Fernández is barred from receiving federal research funds for 15 years. The announcement is the third finding this year from ORI.

The notice follows a decision nearly a year ago by administrative law judge (ALJ) Margaret G. Brakebusch upholding ORI’s findings and recommended debarment, issued in 2022, after an appeal by Fernández. We reported on that ALJ decision after it was made public in February of this year. An exclusion record posted the same day our story ran shows Fernández’s debarment started on March 25. (We reached out to ORI about the case on March 5.)

Judge upholds 15-year debarment against scientist who once threatened to sue Retraction Watch

An appeals judge has recommended the U.S. Health and Human Services uphold a proposed 15-year debarment for a scientist accused of research misconduct more than a decade ago.

In a May 2025 decision, administrative law judge (ALJ) Margaret G. Brakebusch concluded that “undisputed facts” establish Ariel Fernández engaged in research misconduct by falsifying research results in published papers, grant applications and other materials while serving as a professor at Rice University in Houston. Brakebusch recommended HHS affirm the proposed sanctions made by the Office of Research Integrity in a 2022 charging letter — including a 15-year ban from federal funding for Fernández, an Argentine chemist.

The development is the latest in a lengthy saga involving skepticism over Fernández’s work dating back to 2009. Over the years, scientists have criticized his work, journals have investigated his papers, and Fernández has flip-flopped about the funding sources for some of his articles. Fernández also levied a legal threat against Retraction Watch in the past for reporting on an expression of concern in one of his papers.

Porn addiction recovery group sues publisher, UCLA researcher over critical paper

An online peer support group for people overcoming addiction to pornography has filed a lawsuit against the authors of a paper critical of the group, as well as the publisher Taylor & Francis, in an attempt to get the article retracted.

The 2023 study, published in Deviant Behavior, found the Reddit channel for the group NoFap had a higher rate of posts containing violent language compared with two similar subreddits.

Study coauthors Nicole Prause, a bioinformatics programmer with the University of California, Los Angeles, and clinical psychologist David Ley are named defendants in the lawsuit, filed December 30. NoFap and the group’s founder, Alexander Rhodes, are plaintiffs in the suit, which alleges the authors manipulated the data to make the subreddit seem uniquely violent.

Court challenge could chill reporting of research fraud, say whistleblower attorneys

The U.S. government recently announced a record $6.8 billion in False Claims Act settlements and judgments in 2025, the most in a single year since the law’s enactment 163 years ago. For those concerned with scientific integrity, another significant FCA record was also set in 2025: the number of suits brought under the FCA by private individuals against entities they believe defrauded the federal government.

Successful qui tam suits brought under the FCA can come with incentivizing monetary rewards – sometimes substantial – for the whistleblowers. Whistleblowers filed a record 1,297 of these so-called qui tam lawsuits in 2025, up from 979 suits in 2024.

Despite the FCA’s banner year, legal experts say a pending challenge may weaken the law’s whistleblower power and impact. A Florida district court recently struck down the FCA’s qui tam provisions as unconstitutional because these suits involve individuals suing on behalf of the government. If an appeals court upholds the decision, some whistleblowers in that court’s jurisdiction may no longer get paid for exposing wrongdoing, a change that could allow more fraud to slip under the radar, legal analysts say.

Lawsuit fails to block retraction of paper claiming to link heart-related deaths to COVID-19 vaccines

*Greg J. Marchand in a photo from his research institute’s website.*

A Taylor & Francis journal has retracted a widely-read paper linking cardiac-related mortality to COVID-19 vaccines after an unsuccessful legal attempt by the lead author to block the withdrawal. That author says he is considering further legal action against the publisher.

The article, “Risk of all-cause and cardiac-related mortality after vaccination against COVID-19: A meta-analysis of self-controlled case series studies,” drew swift criticism when it was published in Human Vaccines & Immunotherapeutics in August 2023. At the time, critics and sleuths were quick to challenge the data and methods used in the paper, which now has more than 143,000 views on the Taylor & Francis website and has been cited 15 times, including by two letters to the editor of the journal and a response from the authors, according to Clarivate’s Web of Science.

The retraction notice, posted online January 16, states the retraction resulted from concerns that arose about the methodology of the study and the integrity and availability of the data. The authors provided a full response to the queries; however, the publisher determined the validity of the findings remained in question, the notice states. It continues:

Court: University disclosure of researcher’s misconduct did not violate due process

An appellate court has dismissed a legal challenge by a cancer researcher against her former institution, ruling the university’s misconduct investigation and disclosure process did not violate her right to due process.

In 2020, The Ohio State University determined that Flavia Pichiorri, a former postdoc in the lab of Carlo Croce, was responsible for manipulating and reusing images in four publications, spanning from her time in Croce’s lab through establishing her own lab at Ohio State. Pichiorri sued the Ohio State Board of Trustees in April 2023 alleging the release of its misconduct findings to “prestigious journals” and her new employer violated her due process rights, defamed her, and inflicted emotional distress, among other claims.

But in a December 19 ruling, the U.S. Court of Appeals for the Sixth Circuit concluded Pichiorri’s complaint never identified an adequate “liberty interest” worthy of procedural protections under the Due Process Clause of the 14th Amendment. The appeals court affirmed a lower court’s decision tossing the complaint for failure to state a constitutional claim.

Court tosses out researcher’s bid to overturn funding ban

A federal court has terminated a former researcher’s lawsuit against the U.S. government agency that barred her from receiving federal funds following an agency investigation that lasted 10 years.

Ivana Frech — formerly Ivana De Domenico — sued the U.S. Office of Research Integrity (ORI) in 2023 after the agency concluded she engaged in research misconduct while at the University of Utah, by “intentionally, knowingly, or recklessly falsifying and/or fabricating” images in work funded by the National Institutes of Health. In her legal complaint filed shortly after ORI’s debarment, Frech alleged the agency’s misconduct findings and debarment decision were “arbitrary, capricious, an abuse of discretion, unsupported by substantial evidence, and contrary to law and regulation.”

On December 12, the U.S. District Court for the District of Columbia threw out Frech’s suit, ruling in favor of the government’s motion for summary judgement. Summary motions are granted when a court finds no genuine dispute over material facts and a lack of conflicting evidence for a jury to weigh. The decision allows ORI’s three-year debarment – which runs through August 2026 – and misconduct conclusions against Frech to stand.

Computing society pulls works for ‘citation falsification’ months after sleuth is convicted of defamation

An international computing society has begun retracting conference papers for “citation falsification” only months after the sleuth who flagged the suspect articles was convicted for defamation in a lawsuit filed by one of the offending authors.

So far, the Association for Computing Machinery (ACM) has pulled at least 27 of the papers, but dozens more remain, according to Solal Pirelli, a software engineer in Lausanne, Switzerland, who raised concerns about the articles more than two years ago. Some of the proceedings allegedly include plagiarized works, while others are plagued by citation stuffing.
