A new journal record: Sage title retracts 678 more papers, tally over 1,500

The retraction of “a final batch” of 678 articles concludes Sage’s investigation into questionable peer review, citation manipulation, and other signs of paper mill activity at one of its journals, according to the publisher.

Sage has been investigating the Journal of Intelligent and Fuzzy Systems (JIFS) since early 2024 for “indicators that raised concerns about the authenticity of the research and the peer review process underlying these articles,” a Sage spokesperson told us. We reported in August on Sage’s retraction of 467 articles from the journal. The publisher retracted another 416 papers in January. With this latest batch, “our investigation into JIFS is now concluded,” the spokesperson said.

Sage acquired JIFS in November 2023 when it bought IOS Press. The indexing company Clarivate raised concerns about the quality of the articles in the journal shortly after and put the journal’s indexing on hold. Its entry on the Clarivate website still shows the “on hold” flag.

Biochemist with previous image duplication retractions loses another paper

A researcher who retracted two papers last year following a years-long investigation has lost another, this one two decades old.

The same journal also corrected two papers for image duplication within days of the retraction.

The moves followed comments about image similarities on PubPeer. The retraction marks the third for biochemist Dario Alessi, a professor at the University of Dundee in Scotland. Two of his papers were retracted in 2024, a process that took six years and included a four-year investigation by the university.

Chinese funding agency sanctions 26 researchers in latest misconduct report

The organization responsible for allocating basic research funding in China has issued misconduct findings against 26 researchers for violations ranging from breach of confidentiality to image manipulation, plagiarism, and buying and selling authorship.

The National Natural Science Foundation of China, or NSFC, released the results of 15 misconduct investigations on April 11. Several of the investigations involved teams of researchers and many included specific published papers, 53 in total. China has been taking steps to crack down on academic fraud, calling last year for a review of all retracted articles in English- and Chinese-language journals.

Penalties for the researchers ranged from bans on applying for funding or serving as a reviewer, to having research funding revoked — which includes having to return funds already dispersed. In most cases, the restrictions on applying for funding were for three to seven years.

Replication probe finds ‘statistically improbable data’ tied to institute in Bangladesh

A Bangladesh-based organization focused on development economics and its founder have been churning out papers filled with misstatements, inconsistencies, ethical lapses and “statistically improbable data,” according to researchers involved in an ongoing effort to replicate the work.

One journal has already retracted a paper for falsely claiming to describe a randomized, controlled trial and data collection that failed to adhere to the journal’s ethical guidelines. The study, published in the European Economic Review, was retracted following a March 11 report from the Institute for Replication, or I4R. The group is conducting a broader probe into the Global Development & Research Initiative (GDRI), the organization that implemented the intervention described in the paper.

GDRI’s founder and the study’s sole author is Asad Islam, a developmental economist at Monash University in Australia. Since 2022, Islam has received over $2 million in funding from the Bill & Melinda Gates Foundation, the World Bank, the Asian Development Bank, and other organizations, according to a copy of his resume. Islam did not respond to multiple requests for comment on the retraction or the broader concerns about the work. But in a statement posted to his now-deleted account on X, he wrote:

A ‘joke’: Paper with ‘completely irrelevant’ citations retracted

A paper that made the rounds last year for its blatantly “irrelevant” citations has now been retracted.

Elsevier’s International Journal of Hydrogen Energy published “Origin of the distinct site occupations of H atom in hcp Ti and Zr/Hf” in November 2024.

Paragraph seven of the introduction consists of a single sentence: “As strongly requested by the reviewers, here we cite some references [35-47] although they are completely irrelevant to the present work.” One of the authors told us they included the references as a “joke” after reviewers pressured them.

All 13 of the references include Sergei Trukhanov as an author, and all but one also includes Alex Trukhanov.

Indian university’s channel on publisher’s platform disappears

Screenshot of Saveetha University’s Cureus channel from February 6, 2025

The Saveetha Institute of Medical and Technical Sciences in India has been on our radar for a while. So when we got word the university’s channel on an open access journal platform disappeared, we were curious what might be going on.

Just this year, we reported Saveetha was among 14 universities with “questionable publication practices,” defined as unusually fast growth in research output, as measured by published journal articles.

Our 2023 investigation into Saveetha’s dental school uncovered an elaborate self-citation scheme: Undergraduates write manuscripts as part of their exams; student and faculty reviewers then insert scores of citations to papers by Saveetha faculty to inflate the university’s citation rankings.

Math journal editors resign to launch open-access title ‘free from pressure or influence’

The managing editors and entire editorial board of Mathematical Logic Quarterly, a Wiley title, have resigned, citing “unilateral decisions” by the publisher “that affected the editorial process.”

“We do not believe that Wiley is currently providing an environment that allows the editors to do their editorial work according to the standards of the academic community and free from the negative influence of commercial and profit-oriented interests,” the editors wrote in their resignation letter.

The editors have launched a new journal with a “diamond” open-access model, not charging fees to read or publish papers.

Former Italian university head faces retractions and criminal investigations

A prominent Italian pharmacologist under investigation for embezzlement and rigging university contracts has garnered a dozen and a half retractions in the last year for image alterations and duplications.

But Salvatore Cuzzocrea, the former rector of the University of Messina, told us he did not agree with the retractions because they were decided “without clear communication,” and that none of the papers had problems that he wasn’t able to reply to.

Cuzzocrea, a professor of pharmacology at Messina, is set to face an Italian court over rigging bids for university contracts and is under investigation for allegedly embezzling more than 2 million euros worth of reimbursements.
