A chemistry paper on nanorods that became a lightning rod for criticism on chemistry blogs this week has been retracted.
Here’s the notice for “Chopstick Nanorods: Tuning the Angle between Pairs with High Yield,” originally published in June in Nano Letters by Rajasekhar Anumolu and Leonard F. Pease of the University of Utah: Continue reading Nano Letters retracts chopstick nanorod paper questioned this week on chemistry blogs
An assistant professor of neuroscience at Tufts has withdrawn a paper published last year after one round of corrections wasn’t enough to fix all of the study’s problems.
The study, “Sirtuin 2 (SIRT2) enhances 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced nigrostriatal damage via deacetylating forkhead box O3a (Foxo3a) and activating Bim protein,” by Gizem Donmez and colleagues, had already been subject to an extensive correction in May: Continue reading Authors withdraw already-corrected JBC paper questioned on PubPeer
An Australian university has put a hold on trials of an experimental drug for skin cancer whose main developer has been dogged by charges of research misconduct for several years.
The Australian Broadcasting Corporation is reporting that the University of New South Wales has suspended trials of the drug, DZ13, while it investigates the work of Levon Khachigian, who is leading the studies.
According to the news organization, Khachigian and his group were cleared by the school in two prior inquiries. However, additional accusations of misconduct — specifically involving image manipulation and misuse — prompted a third investigation.
We’ve found four retractions of Khachigian’s studies, from the Journal of Biological Chemistry and Biochemical and Biophysical Research Communications, between 2009 and 2010 (before the launch of Retraction Watch).
Since last May, we’ve been reporting on a case at the University of Utah involving two retractions and two corrections. When the story first broke, the lab blamed a former worker for inappropriately removing data from the premises, and the university has been investigating. Last month, we reported that Ivana De Domenico, the junior faculty member who was first author on those papers, had left the university, and that senior author Jerry Kaplan had retired.
But the problems went beyond the four papers we reported on, as the Salt Lake Tribune reported on Friday. In a 9-page report provided to the Tribune, the panel overseeing the investigation details its examination of 11 papers. This is the first of six findings: Continue reading University of Utah finds former faculty member guilty of misconduct because of “reckless disregard”
Alirio Melendez, who has already had 12 papers retracted from various journals and been found guilty of scientific misconduct by a former employer, has had a Science paper retracted.
Here’s the notice (which is behind a paywall): Continue reading Melendez Science paper retracted, making 13
The University of Tokyo panel investigating the work of a former professor there, Shigeaki Kato, has recommended the retraction of 43 of his group’s articles, according to a report in the Asahi Shimbun newspaper.
If the papers are indeed retracted, Kato, who already has at least five articles subject to an expression of concern and five retractions, would be fifth on the list of most retractions for a single author, by our unofficial tally. His fellow countryman, Yoshitaka Fujii, continues to hold the lead at what appears to be 183, followed by Joachim Boldt (~89), John Darsee (~83), and Diederik Stapel, at 53. [See note at end.]
The Asahi report quotes Kato — who has received some $20 million in government funding for his work — as acknowledging problems with the data in his studies: Continue reading Tokyo panel calls for retraction of 43 Kato papers
A lab run by a Canada Research Chair at the Ottawa Research Institute has retracted a paper — in a journal the chair edits — for what sounds a lot like inappropriate image manipulation.
Here’s the notice from Skeletal Muscle: Continue reading Paper by Canada Research Chair retracted from journal he edits for blots “from unrelated samples”
So how long do researchers have to keep records of experiments?
We had that question while reading the retraction notice for a 2007 paper in the Journal of Clinical Investigation: Continue reading JCI paper retracted for duplicated panels after authors can’t provide original data
The Journal of Neuroscience has retracted a 2009 article by a group from Mount Sinai (now the Icahn School of Medicine at Mount Sinai) for suspicious Western blots.
The paper, “Requirement for Protein Synthesis at Developing Synapses,” came from the lab of Deanna Benson, a Parkinson’s expert. According to the abstract, which is still available on the journal’s website:
Two studies by Adam Savine, the former Washington University neuroscience graduate student found by the Office of Research Integrity to have falsified data, have been retracted.
Here’s the notice for one: Continue reading Retractions arrive for former Wash U neuroscience grad student found to have committed misconduct
