The steady drip-drip-dripping sound you hear from the cancer literature these days comes from the stream of retractions involving studies by Naoki Mori, the now jobless scientist whose work on cancer viruses appears to be evaporating before our eyes. Cancer Science, which used to be called the Japanese Journal of Cancer Research, has retracted three … Continue reading And that’s 14: More (and more) Mori retractions, as Japanese cancer journal pulls three papers
We’ve had two questions since learning of the fraud case involving Naoki Mori: Who discovered the manipulations? And how? We now have answers. We recently received an e-mail from a researcher who specializes in Mori’s field — cancer viruses — and who claims to have been a reviewer of a paper he submitted early last year … Continue reading Cracking the Mori case: A reviewer describes how manipulated images came to light
We’ve been honored by all the attention Retraction Watch has been getting for breaking the story of Naoki Mori—the Japanese virologist who recently received a 10-year publishing ban from the American Society of Microbiology over concerns that he manipulated his images. Mori’s retraction count is now up to 11, we’ve been able to report with … Continue reading Mori, now up to 11 retractions, was dismissed in August over fraud matter
A Nobel prize-winning genetics researcher has retracted two more papers, bringing his total to 13. Gregg Semenza, a professor of genetic medicine and director of the vascular program at Johns Hopkins’ Institute for Cell Engineering in Baltimore, shared the 2019 Nobel prize in physiology or medicine for “discoveries of how cells sense and adapt to … Continue reading Nobel prize-winner tallies two more retractions, bringing total to 13
It’s Nobel Prize week, and the work behind mRNA COVID-19 vaccines has just earned the physiology or medicine prize. But this is Retraction Watch, so that’s not what this post is about. A Nobel prize-winning researcher whose publications have come under scrutiny has retracted his 10th paper for issues with the data and images. Gregg … Continue reading Nobel Prize winner Gregg Semenza tallies tenth retraction
A Johns Hopkins researcher who shared the 2019 Nobel Prize in Medicine or Physiology has retracted four papers from the Proceedings of the National Academy of Sciences (PNAS) for concerns about images in the articles. Gregg Semenza is “one of today’s preeminent researchers on the molecular mechanisms of oxygen regulation,” the work for which he … Continue reading Nobel Prize winner Gregg Semenza retracts four papers
Ever since we broke the news about the issues with the now-retracted Science paper about changing people’s minds on gay marriage, we’ve been the subject of a lot of press coverage, which has in turn led a number of people to ask us: Who has the most retractions? Well, we’ve tried to answer that in … Continue reading Who has the most retractions? Introducing the Retraction Watch leaderboard

Here’s our unofficial list (see notes on methodology), which we’ll update as more information comes to light: Joachim Boldt (220) See also: Editors-in-chief statement, our coverage Yoshitaka Fujii (172) See also: Final report of investigating committee, our reporting, additional coverage Yoshihiro Sato (124) See also: our coverage Hironobu Ueshima (124) … Continue reading The Retraction Watch Leaderboard
A pair of engineering researchers has analyzed the work of a handful of prolific scientific fraudsters, and has concluded that science needs a “shame list” to deter future misconduct. The paper, “Analysis and Implications of Retraction Period and Coauthorship of Fraudulent Publications,” by Jong Yong Abdiel Foo and Xin Ji Alan Tan, of Ngee Ann … Continue reading Does science need a retraction “shame list?”
Carcinogenesis has the publishing world’s version of a twin problem: two dysfunctional articles yet one gets retracted while the other merely suffers a correction. Is it nature — or nurture? Here are the details. One article, “Chemopreventive effect of dietary glutamine on colitis-associated colon tumorigenesis in mice,” came from a group in China. Published earlier … Continue reading Journal takes different tacks on two cancer papers with image problems
