On Wednesday, we reported on a Nature retraction of a paper whose corresponding author had also had a Cell paper retracted, and had been found to have committed a “violation of academic integrity” by Utrecht University. Today, we present the back story of how those retractions came to be, from another co-author of both papers, Ben Scheres, of Wageningen University: Continue reading “I am deeply saddened and disturbed:” Co-author of retracted Nature paper reveals how problems came to light
There have been a number of developments in the unraveling of two Nature studies out of the RIKEN Institute in Japan and Harvard purporting to show an easy way to create stem cells. There was an interim report of RIKEN’s investigation last Friday, and more details emerged this week.
And today, the Japan Times reported that last week, a correction of a 2011 paper by many of the same authors appeared in Tissue Engineering Part A. Here’s the correction notice, dated March 13: Continue reading Authors of controversial STAP stem cell study author correct 2011 paper
A 2013 paper in Nature that was among those whose first or last author had committed a “violation of academic integrity,” according to Utrecht University, has been retracted.
Here’s the notice: for “CLASP-mediated cortical microtubule organization guides PIN polarization axis,” whose corresponding author was Pankaj Dhonukshe: Continue reading Nature paper by researcher found to have violated academic integrity retracted
A co-author of two papers claiming to have shown how to create stem cells simply and easily has requested their retraction, the Wall Street Journal is reporting: Continue reading Co-author of controversial acid STAP stem cell papers in Nature requests retraction: report
An international team of researchers from the NIH, Harvard, the University of Michigan, and two Chinese universities — Fourth Military Medical University and China Medical University — has retracted their 2012 paper in Nature after they — and a number of other groups — were unable to reproduce the key results.
The original abstract for “The NAD-dependent deacetylase SIRT2 is required for programmed necrosis” said that the findings
implicate SIRT2 as an important regulator of programmed necrosis and indicate that inhibitors of this deacetylase may constitute a novel approach to protect against necrotic injuries, including ischaemic stroke and myocardial infarction.
But here’s the notice, by corresponding author Toren Finkel and colleagues: Continue reading Nature paper retracted following multiple failures to reproduce results
We have an update on the case of Pankaj Dhonukshe, a scientist about whom we reported in November. Utrecht University has found that Dhonukshe, a former researcher at the Dutch university, committed “a violation of academic integrity” in work that led to a number of papers, including one published in Nature and once since retracted from Cell.
Here’s the university’s statement: Continue reading Utrecht University finds “violation of academic integrity” by former researcher
A 2013 article in Antonie van Leeuwenhoek Journal of Microbiology has been retracted for a few reasons.
Here’s the notice for “The effects of each beta-glucosidase gene deletion on cellulase gene regulation in Neurospora crassa:” Continue reading “Inconsistent errors” and unknowing authors force retraction of microbiology paper
A pair of researchers at the University of Maryland have retracted a paper in Cell Death & Differentiation after it became clear that one of the figures had been duplicated from an earlier paper.
Here’s the notice, dated December 13, 2013, for “INrf2 (Keap1) targets Bcl-2 degradation and controls cellular apoptosis,” by Suryakant Niture and Anil Jaiswal: Continue reading Figure duplication kills cell death paper
Blood has retracted two 2013 illustrations of red cells by researchers from South Africa and the United States because, somewhat confusingly, they didn’t conform to the journal’s criteria for publishing such material.
Here’s the notice for one of the images, “Red blood cell and platelet interactions in healthy females during early and late pregnancy, as well as postpartum”: Continue reading Blood retracts two red cell illustrations that “could have misled” readers
Shigeaki Kato has two more retractions, both in the Proceedings of the National Academy of Sciences (PNAS).
Here’s one of the notices: Continue reading Shigeaki Kato notches retractions 16 and 17, in PNAS
