Defamation suit demanding Elsevier retract paper heads closer to trial

A trial date has been set in a $1 billion defamation case against Elsevier that alleges the company published what plaintiffs say was a manipulated study about an air purifying technology over objections from peer reviewers. The case has already cost Elsevier a $10,000 sanction from a judge.

Global Plasma Solutions (GPS), which makes air quality products, sued Elsevier in 2022 after the publisher declined to retract a 2021 paper in Building and Environment about GPS’ needlepoint bipolar ionization technology, which it heavily marketed during the COVID-19 pandemic as an air purifier. The complaint claims Elsevier is responsible for the authors’ alleged omission of data and misleading conclusions in the paper that fueled “massive” financial losses for the company, its lawyers claim. Elsevier knew the paper “failed peer review” under its “own standards,” but moved forward with the article despite this knowledge, according to GPS, which now goes by GPS Air.

The complaint has survived a bid by Elsevier to dismiss the case, and a trial has been set for Dec. 7. In allowing the case to proceed, U.S. Magistrate Judge David Keesler said in a May 2024 opinion that GPS has “plausibly alleged actual malice” by Elsevier defined as “knowledge of falsity or reckless disregard for the truth.” Chief Judge Martin Reidinger of the U.S. District Court for the Western District of North Carolina upheld Keesler’s recommendation in July 2025.

Ceramics journal pulls dozens of papers flagged for integrity concerns

A materials science journal has pulled 56 papers so far this year for transgressions including image overlap, concerns about data integrity and “suspicious” changes in authorship.

Ceramics International began retracting the papers in July. More than 50 of the retractions were requested by an “impartial field expert acting in the role of an independent Publishing Ethics advisor,” according to the notices.

Most of the retraction notices – 43 – reference PubPeer comments calling out issues with the work. In emails we have seen, scientific sleuth Mu Yang flagged 80 papers from Ceramics International to the journal’s publisher, Elsevier, on April 23, 2025.

Sage issues dozens of retractions from two journals it acquired

In recent weeks Sage has retracted batches of articles published in two journals it acquired from IOS Press in 2023. In each case, the retractions were for manipulation of, and concerns about, peer review.

The first tranche of papers was retracted July 15 from Journal of Intelligent and Fuzzy Systems (JIFS) and constituted 43 papers, some of which had been presented at a conference in Türkiye. According to the retraction notice, after an internal investigation, Sage “became aware that the submissions contain indicators of third-party involvement and attempts to manipulate the peer-review process” in the special issue.

The second batch of retractions applied to 34 papers in the International Journal of Knowledge-Based and Intelligent Engineering Systems from 2017 to 2025. The August 5 notice cites suspicion of third party involvement, peer review issues, citation manipulation and non-standard language, including tortured phrases, as reasons for retracting the articles. Tortured phrases can indicate plagiarism.

Princeton student says she did not conduct the experiments described in her now-retracted paper

A figure from the now-retracted paper in *Macromolecular Materials and Engineering* shows the “hypothesized effects” of the experiments described in the study.

Earlier this week, Retraction Watch reported on a Princeton student’s decision to retract her own paper from an engineering journal due to “significant methodological errors.” The student, Rishika Porandla, now tells us she never conducted the experiments described in the study.

“The beam experiment described in the paper was a proposed experimental workflow with associated calculated results,” she wrote in an email. “Public confusion led me to recognize and regret that this is not clear in the retracted publication, and I have included detailed clarification in an updated retraction statement to Wiley.”

Porandla’s original article, published in 2024 in Macromolecular Materials and Engineering based on work she did while in high school, claimed to show it was possible to enhance the biodegradation of polyvinyl chloride, or PVC, by mixing it with gold nanoparticles and blasting it with an electron beam.

A college student had to retract her paper. The move was ‘the starting point for a better study’

Rishika Porandla published a paper based on research she did in high school. As a sophomore at Princeton, she revisited the work — and found errors in the methodology, leading her to retract the study.

Note, August 14, 2026: See an update to this story: “Princeton student says she did not conduct the experiments described in her now-retracted paper.”

As a sophomore at Princeton University, Rishika Porandla took a course called “The Curious Scientist,” where students practice disciplinary research skills and act as a “PI” on a project of their choosing.

Porandla didn’t have to think twice about what subject to dive into. In high school, she had studied the biodegradability of polyvinyl chloride and discovered a new process to break down the plastic. The finding led to one of her proudest high school achievements — a published journal article. She was eager to use the Princeton class to advance her discovery.

From the outset, Porandla’s project for the class seemed like “a slam dunk,” Andrea DiGiorgio, the course’s instructor, told Retraction Watch.

Clarivate removes hold on mega-journal Heliyon after internal audit, 650+ retractions

Clarivate has lifted its hold on Heliyon after the journal’s internal audit led to over 1,000 retractions, expressions of concern and corrections. As a result, the journal will receive an impact factor in the coming cycle, a Clarivate spokesperson said.

Clarivate decided in September 2024 new content from Heliyon would not be indexed in its Web of Science due to concerns about quality. The journal told us at the time it was “investigating,” and since then, it has retracted over 650 articles.

Clarivate lifted the hold on May 14, and Heliyon released a statement shortly after, noting all content published while the journal was on hold will now be indexed. The statement says the audit “revealed behaviors that did not align with our policies.” As we wrote in February, the journal has previously said the concerning practices included compromised peer review, authorship irregularities, tortured phrases and citation manipulation.

Decade-long fraud by market survey firm a ‘gut punch’ for researchers

In April 2025, David Victorson, a psychologist at Northwestern University in Chicago, was polishing several manuscripts for submission when a colleague sent him a link to a press release from the U.S. Department of Justice. “Eight Defendants Indicted in International Conspiracy to Bill $10 Million for Fraudulent Market Survey Data,” the headline read.

Victorson couldn’t believe it. Op4G, a market research company he first worked with more than a decade earlier, was being indicted for selling bogus data between 2014 and 2023. In fact, Victorson had just used them to run an online survey related to meditation as part of a U.S. National Institutes of Health project to create a standardized mindfulness metric. He didn’t yet know whether his own data were compromised, but he knew there was no way he’d be submitting his manuscripts with those data.

“Because they were within the period of the indictment, we scrapped them entirely,” Victorson said. “It took years off our lives.”

RFK Jr. questions another publisher on expression of concern for a vaccine paper

The U.S. Secretary for Health and Human Services is once again questioning a publisher on an editorial action regarding a paper on vaccination.

Published in Sage Open Medicine in 2020, the article looks at health outcomes in vaccinated versus unvaccinated children. Its authors are Brian Hooker and Neil Z. Miller, both longtime vaccine critics.

Sage Open Medicine put an expression of concern on the paper on May 18. “The following article is under investigation,” it reads. “This expression of concern will remain in place until the investigation concludes, and a final decision has been made.”

A composer published a paper on theoretical physics. His lack of credentials drew criticism.

Some people compose music or make YouTube videos for a hobby. That’s Brandon Yates’ job — so in his spare time, he tries his hand at theoretical physics. But his only published paper was questioned because of his lack of professional training in the field — despite the physicist who inspired his work saying the work looks legitimate.

Based in Las Vegas, Yates earns a living as a composer for the animated series called “Death Battle.” He also has had an “intuitive understanding of, and love for, General Relativity for as long as I can remember,” he told Retraction Watch. But he has no formal training in physics and is self-taught, he said.

After watching a video lecture series online by Canadian physicist Eric Poisson, in January, Yates built a computer algebra program to look into rules in general relativity used to fuse two spacetimes across a thin shell, Yates said. By March, he had come across a conditional result he believed to be novel.

High-profile anesthesiologists earning retractions for data, image problems

In July 2021, John Loadsman received a manuscript about a clinical trial that immediately roused his suspicion. Then the editor-in-chief of Anaesthesia and Intensive Care, Loadsman asked the authors for the raw data.

They weren’t pretty. “When I looked carefully at the spreadsheet, I could see entire blocks of data that were repeated,” recalled Loadsman, an anesthesiologist and scientific sleuth at the University of Sydney. “It was obvious that this was cooked.”

He rejected the manuscript, informing both the corresponding author, Reyhan Polat of the University of Health Sciences in Ankara and Etlik City Hospital, in Turkey, and her institution about his concerns. He also made a mental note to have a look at the researcher’s published work. Over the following years, that effort drew in another sleuth and eventually prompted inquiries into more than two dozen papers by a network of researchers in Turkey.
