The University of Tokyo panel investigating the work of a former professor there, Shigeaki Kato, has recommended the retraction of 43 of his group’s articles, according to a report in the Asahi Shimbun newspaper.
If the papers are indeed retracted, Kato, who already has at least five articles subject to an expression of concern and five retractions, would be fifth on the list of most retractions for a single author, by our unofficial tally.

According to the reports, the university has been investigating Shigeaki Kato and his group, affiliated with the Institute of Molecular and Cellular Biosciences, for scientific misconduct. The investigation was prompted by an outside whistleblower’s allegations in January about 24 of Kato’s papers. The whistleblower claimed that the papers manipulated and reused data improperly, and created a YouTube video to spread the word, as ScienceInsider reported earlier this year.
One of the 24 papers, Read the rest of this entry »
