The troubles continue for a bone researcher, who’s lost multiple papers in recent months due to problems ranging from data issues to including authors without their consent.
Now, journals have retracted two more papers by Yoshihiro Sato. And in a sign of the downstream effects that fraud can have, another journal has retracted two meta-analyses by other authors that cited his work.
Earlier this month, the journal Current Medical Research and Opinion retracted the two meta-analyses because they were based on recently retracted papers by Sato, affiliated with Mitate Hospital. The two new retractions of Sato’s papers are a review and a randomized controlled trial.
Sato was not an author on the meta-analyses published in 2008 and 2011; he was, however, first and lead author on all the retracted papers referenced in the notices. The notices state that the trio of authors on the meta-analyses:
As third retraction for prominent physicist appears, university still won’t acknowledge investigation
Despite a university’s attempts to avoid discussing a misconduct investigation involving one of its former (and prominent) researchers, we keep reading more about it.
In the third retraction this year for physicist Dmitri Lapotko, the journal mentions a misconduct investigation at Rice University, which concluded the data had been falsified. Trouble is, whenever we’ve tried to talk to Rice about that investigation, they won’t even confirm it took place.
Here’s the retraction notice for “Transient Photothermal Spectra of Plasmonic Nanobubbles,” published by Langmuir:
A journal has retracted another paper by a graduate student formerly based at Albert Einstein College of Medicine in New York, after she spontaneously confessed to fabricating data.
As we reported in April 2016, principal investigator Florence Marlow alerted the institution’s Office of Research Integrity and two journals about Meredyth Forbes’s admission, prompting an investigation into the extent of the data manipulation.
Three papers were affected: In January 2016, Development flagged one paper with an expression of concern, alerting readers to the potential issues with the data while the authors and Research Integrity Office investigated the scope of the problem. In April 2016, another paper was retracted by Cell Reports; the third, also published in Development, received a correction.
After being accused of falsifying three figures in a submitted manuscript, Mauvais-Jarvis sued his accusers and officials at his former employer — Northwestern University — for defamation and conspiracy in 2011.
In 2014, a judge dismissed the suit. We wish we could tell you more details about it—such as what the university’s misconduct investigation found, or how the lawsuit was concluded—but they remain shrouded in mystery. What we know is based on court records from the lawsuit, which we recently obtained through an unrelated public records request. Even without all the details, it’s a long, sordid tale, involving a lot of finger-pointing and allegations of misconduct.
In 2008, a former research technician in the lab of Mauvais-Jarvis, then an associate professor of medicine at Northwestern University, raised concerns of fabrication in two figures in a paper on the regulation of insulin synthesis that had been submitted the Journal of Biological Chemistry. An inquiry committee at the university unanimously concluded that research misconduct charges against Mauvais-Jarvis were not credible.
But then a third figure in the manuscript was found to be “inaccurate,” and the university initiated a second inquiry. That’s when Mauvais-Jarvis — whose papers have been cited more than 2,000 times, according to Clarivate Analytics’ Web of Science, formerly part of Thomson Reuters — initiated a lawsuit.

Jae Hyo Park, who is pursuing his PhD, and Seung Ki Joo, a professor in the department of material science and engineering at Seoul National University in South Korea, appear on all five papers as first and last author, respectively.
According to an official at IOP Publishing, the retractions began when a third party contacted them last March about “potential misconduct” in a paper published earlier that year in one of its journals—Journal of Physics D: Applied Physics. The IOP official Simon Davies explained: Read the rest of this entry »
Neuroscientist Stanley Rapoport hasn’t had much luck with his co-authors.
Recently, we’ve reported on multiple retractions of papers co-authored by Rapoport after three different first authors were found to have committed misconduct. Now, the fallout from one of those cases had led to four more retractions, bringing Rapoport’s total to 12.
The latest batch of retractions stem from the actions of Jagadeesh Rao.
Here’s the first notice, issued by Psychopharmacology:
According to the notice, a “knowledgeable informant” told the journal about the overlap and “fraudulent” aspects of the paper, which the editors were able to confirm. The journal retracted the paper last month.
Dmitri Lapotko, a Belarusian researcher with a background in laser weaponry, made a name for himself at Rice University in Houston, where he studied the use of nanotechnology to diagnose and treat human diseases. That work earned him significant press coverage, including stories in the New York Times and Science.
But that nanobubble may be bursting. The journal Theranostics has retracted a 2011 paper on which Lapotko is the last and corresponding author, citing questions over data falsification. What’s more, another journal has warned readers there may be a problem with a figure in a 2012 paper on which Lapotko is listed as last author.
Lapotko has since left Rice for Masimo Corp., a developer of monitoring devices for patients in the operating room.
According to the Theranostics notice:
Two blog posts are shining additional light on a recent retraction that included some unanswered questions — namely, the identity of the researcher who admitted to manipulating the results.
To recap: Psychological Science recently announced it was retracting a paper about the relationship between the words you use and your mood after a graduate student tampered with the results. But the sole author — William Hart, an assistant professor at the University of Alabama — was not responsible.
The post raised some questions — for instance, who was the graduate student, and if his or her work was so influential to a paper, why was he/she not listed as an author? Hart declined to identify the student, but two new blogs — including one by one of Hart’s collaborators at the University of Alabama — are providing more details.
Attention Joachim Boldt: The 1990s are calling, and they want their papers back.
The Annals of Thoracic Surgery has retracted two papers from the early 1990s on which Boldt was the first author – bringing the retraction tally for the disgraced German anesthesiologist to 96, by our count. Both articles were found to contain manipulated data.
The first paper, from 1990, was titled “Acute Preoperative Plasmapheresis and Established Blood Conservation Techniques,” and was written when Boldt was on the faculty at Justus-Liebig University, in Giessen.
