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.
Carlo Croce, a cancer researcher who has faced numerous research misconduct allegations, recently accused a former lab member of misconduct. Although an institutional probe did not support that allegation, Croce’s efforts have led to a retraction.
In November 2015, Croce and another cancer researcher at Ohio State University (OSU), Ramiro Garzon, contacted PLOS ONE, alleging that the paper’s corresponding author, Stefan Costinean, published data without their knowledge or permission and without “accurately acknowledging their contributions to the research.” Although the PLOS ONE paper mentioned Croce’s and Garzon’s contributions in the acknowledgements section, the two were not included as co-authors. We have obtained a copy of the report describing OSU’s preliminary probe; it did not find evidence of misconduct, but recommended the paper be retracted for using data without permission. Although Costinean disagreed, the journal has since retracted the paper.
Croce has been on the other side of this process: Seven of his papers have been retracted for issues including manipulation and duplication. After a New York Times article, published in March, explored misconduct allegations against Croce, OSU said the university is “instituting an independent external review.” Croce is currently suing the New York Times, alleging that the newspaper defamed him in the story.
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.
Last year, the fallout from a misconduct investigation at Nanyang Technological University (NTU) in Singapore resulted in the university revoking the PhD of a Harvard research fellow, and a senior researcher losing his job. In July 2016, NTU told us another researcher who could not be named at the time had also come forward and confessed to making up data.
An ethical review board in Sweden is asking journals to retract six papers co-authored by former star surgeon Paolo Macchiarini, after concluding that he and his co-authors committed misconduct.
One of the papers is the seminal 2011 article in The Lancet, which described the first case of a transplant using an artificial trachea seeded with the patient’s own stem cells, and now bears an expression of concern from The Lancet editors. Over time, multiple authors have asked to be removed from the paper.
The Expert Group on Scientific Misconduct at the Central Ethical Review Board has determined that concerns over that paper — and five others co-authored by Macchiarini, once based at the Karolinska Institutet (KI) — were justified. In a press release, it says:
A journal has retracted a 2014 paper after a university investigation found that the first author only reported certain data points that supported the paper’s conclusion.
Based on a whistleblower’s tip, the University of Florida investigated work by Huabei Jiang, a professor of biomedical engineering, and Lei Yao, a former postdoc and scientist in Jiang’s lab, for research misconduct. According to documents obtained by Retraction Watch through a public records request, in 2015 Yao confessed to selectively choosing data in an email to the whistleblower.

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, just shy of 1,000 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 [email protected].
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.
