A chemistry journal has retracted a 2020 review article by a nanotube researcher who fabricated and falsified data in dozens of studies.  

The latest retraction for Naohiro Kameta brings his total to 40, earning him a place on the Retraction Watch Leaderboard.

In a 2020 review article in Chemical Reviews, 24 of the 610 works Kameta and his coauthors cited had themselves been retracted following the publication of the paper, according to the retraction notice. Because these references were “important components” of the review article, “the narrative and claims presented can no longer be upheld,” the notice reads. The review has been cited 164 times, according to Clarivate’s Web of Science.

A microbiologist formerly of Osaka University has lost four papers, with at least one more retraction pending, after an institutional investigation found fabrication and falsification of data in his published research. 

The investigation found evidence of manipulated results in seven of the papers examined. The university published the notice of its completed inquiry, along with a full report in Japanese, on February 6. 

The report did not name the scientists or cite the articles investigated, but it did include a figure or table with altered data from each paper. Three papers retracted in February mentioned an investigation by Osaka University in the notices; Yukihiro Hiramatsu was the first author on all three. Comparing the figures in the report with ones in Hiramatsu’s publications, we identified the seven articles. (See the list here.)

A nanotube researcher in Japan has earned 13 retractions, with more to come, after an extensive investigation by the country’s National Institute of Advanced Industrial Science and Technology (AIST) revealed widespread misconduct in his work. 

AIST’s investigation found Naohiro Kameta, senior principal researcher at the Nanomaterials Research Institute located in AIST’s Ibaraki campus, fabricated and falsified dozens of studies. He was apparently dismissed from his role following the findings. 

The institute first learned of the problems in Kameta’s work in November 2022, according to a translated version of the investigation report. Initially, they looked into five papers, but eventually expanded their scrutiny to 61 articles on which Kameta was the lead or responsible author.

An official journal of the Japanese government has retracted a 2021 paper over concerns about misconduct in the work, which was performed in a national research center. 

Here’s the retraction notice for the paper, titled “Development and Evaluation of Fluorescence Immunochomatography for Rapid and Sensitive Detection of Thermophilic Campylobacter”: 

Food Safety decided to retract this article in which the primary author misconducted as reported from the primary author’s affiliation.

Far more details are available in materials published last December by Japan’s National Institute of Health Sciences, where the first author of the article, Hiroshi Asakura, is chief researcher. According to a press release dated Dec. 26, 2023:

The president of Aizu University in Japan has resigned after two investigations found he had self-plagiarized or double-submitted a dozen papers.

Toshiaki Miyazaki was also found to have “filed an application for a project subsidized by the national government without going through the university official procedures,” which “caused confusion,” according to Aizu. He resigned effective today [July 31].

The move comes more than a year after the first investigation, as we reported, which concluded in February 2022 and found that Miyazaki had self-plagiarized four papers. At that time, he had to forfeit 20% of one month’s salary. 

A month later, according to a report issued last week by the university, Miyazaki “self-reported that there were 12 papers suspected of self-plagiarism.” A preliminary investigation then began, with a full investigation starting in April and lasting until February of this year.

A university in Japan has revoked the doctoral degree of a former student found to have manipulated images and graphs in a dissertation and two published papers.

“Although our university has been working to raise awareness of research ethics in order to prevent research misconduct, it is extremely regrettable that such a situation has occurred,” Tohoku University President Hideo Ohno said in an announcement made on March 30 (translated from the Japanese using Google Translate).

The school did not name the former student, who was first author on both papers. But details mentioned in its investigation report (in Japanese) point to a researcher called Nan Li. Li was also named on a blog in Japan that covered the case (in Japanese).
