You’ve been dupe’d: Results so nice, journals published them twice

With so many retraction notices pouring in, from time to time we compile a handful of straight-forward retractions. Once again, this list focuses on duplications — but unlike other duplications, these authors were not at fault. Rather, these retractions occurred because the publishers mistakenly published the same paper twice — the result of a transfer […]

Sixth retraction appears for bone researcher due to “extensive self-plagiarism”

A bone researcher in Japan has logged his sixth retraction, after acknowledging he duplicated substantial portions of a 2011 paper and added “honorary” co-authors. The retraction, in Parkinsonism & Related Disorders, follows five others for Yoshihiro Sato, including one from JAMA, some of which were pulled over concerns regarding authorship and data integrity. The latest retraction duplicated […]

“All co-authors are honorary:” Team earns fifth retraction

A team of researchers from Japan has earned a fifth retraction, after co-authors told the journal that they did not participate in much of the paper. Yoshihiro Sato, listed at Mitate Hospital, is the only author of the paper who was not “honorary,” the managing editor of the journal confirmed.

Journal retracts three bone papers for duplication by same author

A journal is retracting three papers after a biomaterials researcher duplicated his own work, sometimes using the same figures to describe different experiments. Two of the papers are on bone regeneration; one is about targeting tumors. In addition to issues with figures, two of the retraction notes explain that the papers contain “widespread plagiarism of text” from […]
