A university in Japan dismissed a researcher earlier this month after a probe uncovered evidence of image falsification in several of his papers.
The immunology researcher, Masashi Emoto, denied any wrongdoing. He has said that the experiments in question were performed by another researcher and “he was not responsible” for the falsification.
In 2013, Emoto filed a suit against Gunma University, in which he claimed another researcher possessed the raw data for the experiments in question. Emoto requested those documents be returned to him. However, the court determined that Emoto possessed the raw data.
According to the report — released by Gunma University on October 11 — without the raw data, the university could not prove Emoto committed the misconduct. However, the university determined that, as the corresponding author on the four papers, Emoto was responsible for the work.
When Retraction Watch began in 2010, our co-founders Ivan Oransky and Adam Marcus quickly realized they couldn’t keep up with the hundreds of retractions that appeared each year. And the problem has only gotten worse — although we’ve added staff, the number of retractions issued each year has increased dramatically. According to our growing database, more than 1300 retractions were issued last year (and that doesn’t include expressions of concern and errata). So to get new notices in front of readers more quickly, we’ve started a new feature called “Caught our Notice,” where we highlight a recent notice that stood out from the others. If you have any information about what happened, feel free to contact us at firstname.lastname@example.org.
The Japanese Society of Anesthesiologists (JSA) has requested the retraction of nine additional papers by a co-author of fraudster Yoshitaka Fujii, after investigating allegations of fraud in dozens of papers.
According to the report, a committee investigated approximately 40 publications by Yuhji Saitoh of Yachiyo Medical Center and Tokyo Women’s Medical University and “identified ten publications with clear ethics violations, one of which has already been retracted.”
The author of one of those blogs, Hart’s colleague Alexa Tullett, told us in March that she was retracting another paper she wrote with Hart and the unnamed graduate student. Recently, she confirmed this latest retraction is that paper.
Looking at the author list of the newest retraction, by process of elimination, we now have a lead on the identity of the graduate student who allegedly took responsibility for the misconduct.
Researchers have retracted a 2015 paper in Cell after an investigation revealed the first author committed misconduct.
According to the retraction notice, which first author Ozgur Tataroglu declined to sign, the researchers realized there was an issue with the 2015 paper when they were unable to replicate the findings. Corresponding author Patrick Emery and his team at the University of Massachusetts Medical School in Worcester reviewed the data and found “clear evidence” that Tataroglu — who had been a postdoc in Emery’s lab — “had repeatedly misrepresented and altered primary data,” the notice states.
UMass subsequently conducted an investigation in which it “concluded that the first author committed scientific misconduct.”
The investigation report by UC Denver, which we obtained earlier this year via a public records request, had recommended one of the two newest retractions, which appears in the journal Hepatology. The other retraction, in the Journal of Immunology, was not flagged by the report — which found, among other conclusions, that Almut Grenz had altered multiple values in research that had already been submitted for peer review.
Here’s the notice for the Journal of Immunology paper:
Earlier this year, the University of California, San Francisco and the San Francisco Veterans Administration Medical Center teamed up to write a letter.
Addressed to the editorial office at the American Association of Cancer Research (AACR), the letter, parts of which have been published in a retraction notice, contained information concerning two papers on genetic risk factors for a type of kidney cancer and a type of uterine cancer, respectively, published in different AACR journals over a decade ago by researchers affiliated with the institutions.
The papers had been at the center of research misconduct investigations at both UCSF and the VA and the investigations came to the conclusion that both papers contained:
fabrication or falsification of data that constitutes Research Misconduct.
