Rapid response: Authors retract a PNAS paper within six weeks after Nobel Prize winner spots an error
In the case of a recent paper in the Proceedings of the National Academy of Sciences, the retraction happened within six weeks. Here’s the notice for “Voltage sensor ring in a native structure of a membrane-embedded potassium channel,” by Liang Shi, Hongjin Zheng, Hui Zheng, Brian A. Borkowski, Dan Shi, Tamir Gonen, and Qiu-Xing Jiang, which first appeared online on February 11: Read the rest of this entry »
Musical figures: PNAS paper corrected with version of “intentionally contrived and falsified” Nature figure
One of the two corrections recommended by a McGill committee for work by Maya Saleh and colleagues has appeared, in the Proceedings of the National Academy of Sciences (PNAS).
As we reported last month, the committee found that
two figures in [a] Nature paper had been “intentionally contrived and falsified.” One of those figures was duplicated in a PNAS paper, which also contained an image that had incorrectly labeled some proteins.
The committee recommended that both of the papers be corrected, and the PNAS correction for “Confinement of caspase-12 proteolytic activity to autoprocessing” reads as follows: Read the rest of this entry »
A group of cardiology researchers formerly of the University of Cologne has retracted two papers, after investigations into allegations of misconduct led to an admission of guilt by one of the lab’s junior members.
Here’s the first retraction, for “Connexin 43 acts as a cytoprotective mediator of signal transduction by stimulating mitochondrial KATP channels in mouse cardiomyocytes,” published last week in the Journal of Clinical Investigation: Read the rest of this entry »
ORI sanctions former University of Kentucky nutrition researcher for faking dozens of images in 10 papers
The U.S. Office of Research Integrity has come down hard on a Eric J. Smart, an NIH-funded former University of Kentucky nutrition researcher who faked data in ten published papers and seven grant applications over the past decade.
As two retraction notices in the September 15 issue of the Journal of Immunology note:
On October 19, 1995, the Office of Research Integrity at the National Institutes of Health found that Weishu Y. Weiser, Ph.D., formerly of the Harvard Medical School at Brigham and Women’s Hospital, committed scientific misconduct by falsifying data in biomedical research supported by two Public Health Service grants. As a result, she agreed to submit a letter to The Journal of Immunology to retract this article. The offices of The Journal of Immunology have no record of receiving such a letter and hence the article is now being retracted.
The retractions, for “Recombinant Migration Inhibitory Factor Induces Nitric Oxide Synthase in Murine Macrophages” and “Human Recombinant Migration Inhibitory Factor Activates Human Macrophages to Kill Leishmania donovani,” both say the same thing.
“Recombinant Migration Inhibitory Factor Induces Nitric Oxide Synthase in Murine Macrophages” has been cited 66 times, according to Thomson Scientific’s Web of Knowledge — 40 of those times since the ORI’s report was released. The numbers for the Leishmania paper are almost identical: Read the rest of this entry »
A paper about an alleged cheetah fossil from the Pliocene epoch, dogged by questions since its publication in 2008, has been retracted after one of the authors acknowledged it wasn’t what they thought it was.
Here’s the notice for the paper, “A primitive Late Pliocene cheetah, and evolution of the cheetah lineage:” Read the rest of this entry »
Retraction number four appears in PNAS for work of Alirio Melendez, who has resigned post at U Liverpool
