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.

Springer Nature un-retracts Planck papers, citing “human error”

Today the Retraction Watch list of Nobelists who have retracted papers bids Verabschiedung to Max Planck.

After days of scrutiny, Springer Nature has restored two papers by Planck, who won the Nobel for Physics in 1918, reversing a 2011 decision to retract the articles for “copyright violations.”

Both articles are back, and now carry the following statement:

Former acting director of national research lab in India adds another retraction

A cancer journal has retracted a paper by a former acting director of an institute in India, bringing her retraction total to nine.

Chitra Mandal, a former senior researcher at the Centre for Scientific and Industrial Research’s Indian Institute of Chemical Biology (CSIR-IIC) at Kolkata, served as acting director in 2014-15. She also headed the CSIR’s Innovation complex between 2010 and 2015. She received multiple awards, and was also appointed a Science and Engineering Research Board Distinguished Fellow in 2018.

Mandal has now lost nine articles to retraction and more than two dozen of her papers have been flagged on PubPeer, most for image irregularities or data issues in graphs. In March, Wiley’s Molecular Biology International retracted a 2011 article Mandal coauthored, also for image issues. We previously wrote about an expression of concern on a 2016 paper in which Mandal was a co-author.

The latest retraction involves a 2011 paper in Leukemia Research about the movement of lymphoblasts from the bone marrow to peripheral blood in childhood leukemia. The journal retracted the paper on May 30, citing concerns that some of the data in figures appear to have been manipulated.

Ethics journal retracts paper by high school student for AI, peer review manipulation

The Journal of Medical Ethics has retracted a paper on the use of AI in the pharmaceutical industry for containing references that don’t exist. The article’s sole author: a high school student.

The paper, which argues biased algorithms can exacerbate inequities in health care, was published in September. The author, Irfan Biswas, listed his affiliation as Shrewsbury Public Schools in Massachusetts.

According to the May 28 retraction notice, an investigation by the journal found Biswas used generative AI to “identify and understand referenced sources” and did not verify the references prior to submission.

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.”

Editors of Courant math journal to leave Wiley, establish new roots with independent publisher

Editors of a journal run by a prestigious math institute will close up shop and form a new journal with an independent publisher, with one editor citing Wiley’s increased oversight as the reason behind the move.

Communications on Pure and Applied Mathematics is the journal for the Courant Institute of Mathematics at New York University. The journal has been published in partnership with Wiley for over 75 years, and all the editors of the journal are affiliated with Courant.

In emails Retraction Watch has seen, the editorial board notified Wiley in January that the institute would not be renewing its contract with the publisher once it expired at the end of 2026.

Sex pay ban paper earns a retraction after a long and winding road for an unhappy author

In March 2024, Riccardo Ciacci, an economist at the Universidad Pontificia Comillas in Spain, published a paper claiming Sweden’s ban on buying sex had increased reported rapes by as much as 62%. The finding gained attention on social media, and quickly drew criticism from others in the field.

In particular, a group of three economists took their concerns to social media and to the journal editors, and eventually published a critique of Ciacci’s work. They claimed his analysis reports a statistical relationship not relevant to the finding described in the paper. They concluded there was no large or statistically significant finding.

What followed was a year-long effort to fix the paper, and then ultimately, a decision to retract it. Ciacci, who was not accused of misconduct, said the retraction, which he disagrees with, has cost him a promotion and funding for future research. He also alleges he experienced an onslaught of harassment on social media. In the end, Ciacci maintains the retraction was unjustified, and critics say it came far too late.

Physicist in Iraq fired over publishing scam claims fake Columbia affiliation in new paper

Five months after he was fired by ministerial order, an Iraqi professor of physics at the center of a massive publishing scam submitted a manuscript to a Wiley chemistry journal claiming affiliation with Columbia University in New York City.

The paper also stated the physicist, Oday A. Al-Owaedi, was affiliated with the University of Babylon in Hilla, Iraq, although he was permanently dismissed from his position last year.

As we reported at the time, Al-Owaedi defrauded “researchers by collecting money from them under the pretext of publishing their papers in reputable international journals as promised, while in fact falsifying and forging publication in fake websites,” according to a ministerial order we obtained.
