An experiment deploying AI-generated messages on a Reddit subforum has drawn criticism for, among other critiques, a lack of informed consent from unknowing participants in the community.
The university overseeing the research is standing by its approval of the study, but has indicated the principal investigator has received a warning for the project.
The subreddit, r/ChangeMyView (CMV), invites people to post a viewpoint or opinion to invite conversation from different perspectives. Its extensive rules are intended to keep discussions civil.
The Canadian National Breast Screening Study conducted in the 1980s and led by researchers at the University of Toronto evaluated the efficacy of breast cancer screening in reducing mortality from breast cancer. Because the research was supposedly a “gold standard” randomized controlled trial, its results, published in academicjournals and reported in the media, have influenced public perceptions and informedpolicy on mammography screeningin several countries.
However, over the past decades, flaws in this study have come to light. My colleagues and I learned of failures in randomization, and we and otherresearchers have found other serious problems. We think these flaws strongly suggest the publications of CNBSS results should be retracted. Despite being informed of the flaws in this study in 2021, the University of Toronto has not adequately or appropriately addressed these issues.
The CNBSS was configured as two separate randomized clinical trials, one for women in their 40s at entry and the other for women in their 50s. In CNBSS1, 50,000 women ages 40-49 were supposedly randomly assigned to the intervention arm, in which they would receive up to five annual screens with two view film mammography plus clinical breast examination by a nurse, or to the control arm, where they received a single clinical examination at entry and usual care (essentially, no screening) afterwards. In CNBSS2 for 40,000 women, the randomization was between the intervention of mammography plus a clinical breast exam versus clinical exam only.
Two of the phrases in the paper identified as AI-generated
An expert in AI at Google has admitted he used the technology to help write a preprint manuscript that commenters on PubPeer found to contain a slew of AI-generated phrases like “squared blunder” and “info picture.”
In March 2025, sleuth Guillaume Cabanac, creator of the Problematic Paper Screener, pointed out in a PubPeer comment the paper included several tortured phrases. These phrases indicate AI use and occur when large language models try to find synonyms for common phrases. In Awasthi’s paper, “linear regression” became “straight relapse,” and “error rate” became “blunder rate,” among others.

Scientific Reports has retracted a controversial paper claiming to present evidence an ancient city in the Middle East was destroyed by an exploding celestial body – an event the authors suggested could have inspired the Biblical account of Sodom and Gomorrah.
The decision comes two years after Scientific Reports, a Springer Nature title, published an editor’s note informing readers the journal was looking into concerns about the data and conclusions in the work.
The then-pending retraction was the subject of an April 10 blog post by one of the paper’s authors, George Howard, who called the journal’s decision to remove the article “a profoundly disappointing and frankly disgusting turn of events.”
A lead researcher at UC Davis has lost three decades-old papers from the same journal for image duplication, and the journal says it is investigating more.
Allen Gao, director of research for the Department of Urologic Surgery at the institution is first last and corresponding author on the papers, published in The Prostate.
The journal retracted the articles – published in 2002, 2004 and 2009 – in February. The papers have been cited 42, 71, and 27 times respectively, according to Clarivate’s Web of Science.
A U.K.-based surgeon who was suspended last year for conducting colorectal surgeries that caused harm to hundreds of women has had nine of his research papers flagged and one withdrawn.
In July 2024, Tony Dixon, formerly of Southmead Hospital and Spire Hospital in Bristol, England, was suspended for six months by a tribunal at the Medical Practitioners Tribunal Service (MPTS) after an investigation found the surgeries caused harm in 259 of his patients who underwent a procedure to treat rectal prolapse.
The MPTS panel extended the suspension in January for another six months, during which time Dixon is unable to operate on patients, a spokesperson for the U.K.’s General Medical Council (GMC) told Retraction Watch.
The BMJ’s clinical practice guideline for chronic spine pain
Thirty-four medical professional societies have called for The BMJ to retract a recently published guideline recommending against the use of interventional procedures, such as steroid or anaesthetic injections, to treat chronic back pain.
The journal published the guideline in February as part of its Rapid Recommendations program alongside a meta-analysis and systematic review of published research on the procedures, which the guideline panel used to inform its recommendations. The publications received internationalnewscoverage and enough chatter on social media platforms such as X and Bluesky to placethem in the top 5 percent of all articles scored by Altmetric, a data company that tracks digital mentions of research.
The societies, led by the International Pain and Spine Intervention Society, represent clinicians who prescribe or perform the interventional spine procedures the guideline recommends against. The groups “have serious concerns about the methodology and conclusions drawn in these publications and their potential impact on patient care,” they wrote in a statement dated March 18, and summarized in a rapid response on the BMJ’s website. The statement has since been published in The Spine Journaland Interventional Pain Medicine.
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.
