‘I asked him to stop’: Father adds daughter’s name to over 100 preprints without her permission

An author in China with nearly 500 preprints has continued to add his daughter’s name to papers – despite her insistence she was not involved.

Shifa Liu, whose papers list affiliations with Peking University in China, has posted 499 works (and counting) on topics in physics and mathematics. His daughter, an undergraduate at an American university, is listed as a coauthor on over 100 of those preprints. In some cases, she was even named as the corresponding author. (Retraction Watch is not naming the daughter to respect her privacy and will not be accepting comments that name her.)

The daughter told Retraction Watch she “did not participate in the research, writing, or submission of any of these papers,” adding her father included her name “without my knowledge or consent.”

Major pharmacology journals flag another 15 papers by scientist facing criminal probe

A leading pharmacologist in Italy accused of embezzling research funds is now the subject of coordinated editorial action by one of the field’s professional societies.

The American Society for Pharmacology and Experimental Therapeutics announced expressions of concern for 12 papers, corrections for two and a retraction in an editorial published April 3 in The Journal of Pharmacology and Experimental Therapeutics and Molecular Pharmacology. Salvatore Cuzzocrea, a pharmacology professor at the University of Messina, was a coauthor or corresponding author on all the papers. As we reported previously, Cuzzocrea is being investigated in Italy for allegedly embezzling more than 2 million euros in research reimbursements and allegedly rigging university contracts.

Since our reporting on Cuzzocrea a year ago, journals have retracted five more of his papers. One, from BMC Neuroscience, was retracted 10 days after our reporting for containing data that appeared in an earlier publication. A different paper was retracted last year from Biology for containing overlapping images, another from Biomedicine & Pharmacotherapy for image overlaps, and the International Journal of Molecular Science retracted two more this year for containing duplications and “inappropriate editing” of micrographs.

10 years ago, Elisabeth Bik published a preprint heard around the world

If you are at all familiar with scientific sleuthing, you’re familiar with Elisabeth Bik. She is quoted so often in the mainstream media it is probably difficult to imagine a time before her supersense for spotting similarities in images wasn’t making headlines.

But it was 10 years ago, on April 19, 2016, when she made her debut, when we covered her work screening more than 20,000 biomedical research papers containing western blots. She and coauthors Ferric Fang – a member of the board of directors of our parent nonprofit organization, The Center for Scientific Integrity, and a professor at the University of Washington in Seattle – and Arturo Casadevall, of the Johns Hopkins School of Medicine in Baltimore, posted the work as a preprint on bioRxiv.org and it appeared two months later in mBio.

The preprint was a shot across the bow for journals and publishers, and in the decade since, Bik has advised and mentored others doing similar work. In 2024, she won the Einstein Foundation Award for “identifying misconduct and potential fraud in scientific publications, highlighting science’s problems policing itself.” She donated the proceeds to The Center for Scientific Integrity to create a fund to help other sleuths do their work.

Bik spoke with us earlier this month about the paper, sleuthing and more. The conversation has been edited for clarity and brevity.

45 editors resign from math journal, former EIC calls Elsevier publisher a ‘mini-dictator’

Forty-five of 48 members of the editorial board of the Journal of Approximation Theory resigned earlier this month for what they called Elsevier’s “concerning and potentially detrimental” decisions regarding the publication.

Paul Nevai, formerly a professor at The Ohio State University, was appointed editor-in-chief of JAT in 1990 and held the position for 35 years until December. That’s when he reached the end of his term and Elsevier informed him they’d be filling the position with someone else.

The mass resignation came after what Nevai said were several years of bad blood between the editors of the journal (including him) and the publisher, Giampiero Accardo. A representative for Elsevier told us designated publishers like Accardo are Elsevier employees who “oversee a portfolio of academic journals within a subject area, working closely with editors, authors, and research communities to support their development and long-term success.”

Retraction Watch testifies in Congressional hearing on scientific publishing

Retraction Watch managing editor Kate Travis (center) testified April 15 in a hearing before the Investigations and Oversight Subcommittee of the House Science, Space and Technology Committee. Other witnesses were Carl Maxwell (left) of the Association of American Publishers and Jason Owen-Smith (right) of the University of Michigan.

A hearing on Capitol Hill today explored issues in scientific publishing — and Retraction Watch had a seat at the table.

The Investigations and Oversight Subcommittee of the U.S. House Committee on Science, Space and Technology called the hearing to talk about open access, reproducibility, predatory journals, paper mills and the incentive structure in science. The wide remit meant the committee and witnesses touched on quite a few topics in 90 minutes.

Our testimony, delivered by managing editor Kate Travis, focused on the pitfalls of “publish or perish” and how an overreliance on metrics has incentivized shortcuts in research and publishing. “‘Publish or perish’ is what has allowed businesses like paper mills and predatory journals to flourish, and more recently is leading to an explosion of AI-generated papers flooding journals,” Travis told the subcommittee.

“Game-changer” breast cancer study retracted as Indiana researcher out of his post

A group of cancer researchers whose work has been questioned by sleuths has been hit with their third retraction in less than a year.

Today, Science Translational Medicine (STM) withdrew a 2021 breast cancer study by former Indiana University researcher Yujing Li and 12 other authors for image falsification. The immunotherapy study had been described by senior author Xiongbin Lu as a “game-changer” for triple negative breast cancer in a 2021 IU press release.

The paper’s April 15 retraction notice states that a joint research misconduct investigation involving Indiana University, The Ohio State University, and the University of Maryland, College Park determined “falsification occurred during creation of figure S9C.” The institutions alerted the American Association for the Advancement of Science of the misconduct late last year and requested the paper’s retraction, according to Meagan Phelan, a spokesperson for AAAS, which publishes STM.

BMJ retracts most of a special issue for ‘compromised’ peer review and ‘improbable device use’

BMJ’s Journal of Medical Genetics has retracted the bulk of a seven-year-old special issue for an “irreparably compromised” review process and “improbable device use.”

Of the eight papers in the 2019 special issue, seven were retracted, including an editorial that “almost exclusively” referred to the other now-retracted papers, according to a statement from the journal.

According to the retraction notice published today, the journal’s investigation found the guest editor for the issue selected the peer reviewers, the majority of whom were affiliated with Nanjing University in China. The guest editor is not named in the issue. The publisher’s investigation also found evidence of compromised peer review in almost all articles, the notice states.

Scientist who alleged COVID cover-up circulated a faked NIH email, agency says

A scientist charged with research misconduct used a fake email communication with an NIH researcher’s address to support his claims of governmental retaliation, Retraction Watch has learned.

Last month, we reported on the upholding of a proposed 15-year debarment by a U.S. Department of Health and Human Services appeals judge against Argentine chemist Ariel Fernández for falsifying research while a professor at Rice University in Houston. Administrative law judge Margaret G. Brakebusch based that May 2025 decision on findings by Rice sent to the Office of Research Integrity in 2010 and conclusions from ORI’s independent review completed in 2022.

Fernández denied the misconduct allegations and told us the findings were retaliation by the government for a 2021 paper he wrote supporting a lab origin of SARS-CoV-2. As evidence of the contention, Fernández showed us an email purportedly from National Institutes of Health researcher Joshua Cherry dated June 2021. The email, which appeared to be from Cherry’s NIH address, threatened to resurrect Fernández’s ORI case if he didn’t remove the paper. We could not independently verify the email’s authenticity at the time.
