Earlier this months, a research misconduct scandal in molecular cell biology broke out in the big news. Yoshinori Watanabe, Japanese researcher of cell division and how cells separate their replicated DNA during mitosis and meiosis, was found guilty of scientific misconduct by his University of Tokyo (read the news here and here). This followed an investigation initiated in the fall of 2016, after anonymous whistleblowers submitted to the university a report accusing 6 Tokyo research groups of data manipulation, first and foremost, Watanabe (I managed to obtain this dossier, and publish it below).
As the outcome of the University of Tokyo investigations, which concluded on May 31st 2017, misconduct was determined in 5 publications from Watanabe’s lab, which appeared between 2008 and 2015 in the elite journals like Science, Nature and Nature Cell Biology. However, the whistleblower dossier lists 7 papers, one of them a paper in Cell from 2015 with duplicated gel images, and a 2011 EMBO Reports paper which contains a western blot which was obviously digitally retouched to remove unwanted bands. Watanabe’s assistant professor Yuji Tanno was also found guilty of misconduct, and indeed his 2015 Science paper with Watanabe looks like a total train wreck of data manipulations. Yet it seems there is a tendency to present Watanabe’s deeds as mere mistakes (though grossly inappropriate ones) by a great genius scientist, who was confused by the complexity of rules on data acquisition and incidentally broke some while producing outstanding and absolutely reliable top-level research. Some of his peers seem to be calling for leniency or at least some understanding for Watanabe. The selected evidence from the whistleblower dossier which I post below suggests that Watanabe knew perfectly well what he was doing, and he did so in order to produce desirable results which his lab experiments failed to deliver, and which he needed in order to impress the choosy elite journals.
