When researchers submitted a paper about a type of microparticle to PNAS, they wanted to give credit where it was due, and cite an unpublished manuscript that helped guide their work. But the journal’s policy forbid citing unpublished work, and the reference was removed before publication. Now, concerns from the authors of that unpublished work have prompted the journal to have a change of heart.
What Caught Our Attention: In a letter to the editor, researchers led by Mark Bolland recently outlined the many reasons why a study by Yoshihiro Sato and colleagues in The American Journal of Medicine was “unreliable,” including evidence that the patient numbers were not achievable as described, and inconsistencies and errors in the study data. And let’s not forget a 2016 analysis (co-authored by Bolland) which cast doubt on Sato’s body of work, suggesting that more than 30 of his papers could be problematic.

An investigation by Kyoto University in Japan has found a researcher guilty of falsifying all but one of the figures in a 2017 stem cell paper.
Yesterday, Kyoto University announced that the paper’s first author, Kohei Yamamizu, had fabricated and falsified data in the Stem Cell Reports paper. According to the investigation report, none of the other authors were involved in the data manipulation.
A spokesperson for the journal told us that the authors disclosed the problems last week and Stem Cell Reports will be retracting the paper, published last February.
In the university’s official statement, Yamanaka said: Continue reading Researcher at Japan stem cell institute falsified nearly all images in 2017 paper
A university in Japan has found a former professor guilty of falsifying and altering images in four published papers, including a 2014 paper about stem cells.
According to the report, which we translated, Miura resigned as associate professor at Tottori University a month before the investigation concluded in October of this year. Miura had already stopped receiving grant and research funding in May, one month into the six-month investigation. Continue reading University in Japan finds cancer researcher guilty of misconduct
A professor at a Japanese teachers college has admitted to plagiarism, according to a university report, and was suspended for one month.
On Nov. 24, Hyogo University of Teacher Education announced the results of a misconduct investigation; according to the report, the professor confessed to plagiarizing in a paper.
We translated the notice and were able to learn a little bit about the investigation. Notably missing: both the professor’s and paper’s names.
Here’s how the investigation happened, according to the report: Continue reading University in Japan suspends professor one month for plagiarism
As a bone researcher continues to accrue retractions, an investigation at his former university has found misconduct in more than a dozen papers.
On Nov. 15, Japan’s Hirosaki University announced it had identified fabrication and authorship issues in 13 papers by Yoshihiro Sato, and plagiarism in another.
Sato, a professor at Hirosaki University Medical School from 2000 to 2003, died in January. He was last affiliated with Mitate Hospital. Multiple retractions in recent months have pushed Sato higher up our leaderboard; by our count, he now has 23 retractions and the university said there are likely more to come. Continue reading University investigation finds misconduct by bone researcher with 23 retractions
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.
According to our English version of the report, which we translated from Japanese using One Hour Translation, the committee concluded: Continue reading Researcher dismissed from university for suspected misconduct denies responsibility
In 2016, three researchers published data they had collected on a series of devastating earthquakes that hit Japan earlier that year.
But, in late September 2017, one of the authors—Hiroyuki Goto—revealed that the Kumamoto Earthquake data contained “wide reaching errors”—and an outside expert had warned him the data might be problematic nine months earlier.
Goto, an associate professor in the Disaster Prevention Research Institute at Kyoto University, issued two statements in which he acknowledged the errors, but did not indicate how they occurred. According to The Japan Times, Japan’s Ministry of Education, Culture, Sports, Science and Technology is investigating whether the data “was falsified or fabricated due to inconsistencies with other readings taken nearby.” A report in another Japanese paper, The Mainichi, notes that Osaka University—where one of the authors, Yoshiya Hata, works—is looking into the matter as well.
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.”
Saitoh has collaborated on many papers with Fujii, an anesthesia researcher with more than 180 retractions. As we reported, Saitoh resigned from the JSA when the investigation began, and the society permanently banned him. Continue reading Society recommends 9 retractions for co-author of researcher with record number of retractions
According to the journal, Regenerative Medicine, the ethical issue is that the authors failed to report the case to the Ministry of Health, Labor and Welfare of Japan, which violates the country’s guidelines for conducting stem cell research. Unfortunately, we don’t know much more than that about what happened.
Laura Dormer, editorial director of Future Science Group, which publishes Regenerative Medicine, explained that the paper’s first author, Masato Kantake, requested the retraction because: Continue reading Case report of stem cell therapy in child didn’t meet “ethical standards,” says journal
