“Truly extraordinary,” “simply not credible,” “suspiciously sharp:” A STAP stem cell peer review report revealed
Retraction Watch readers are of course familiar with the STAP stem cell saga, which was punctuated by tragedy last month when one of the authors of the two now-retracted papers in Nature committed suicide.
In June, Science‘s news section reported:
Sources in the scientific community confirm that early versions of the STAP work were rejected by Science, Cell, and Nature.
Parts of those reviews reviews have surfaced, notably in a RIKEN report. Science‘s news section reported:
For the Cell submission, there were concerns about methodology and the lack of supporting evidence for the extraordinary claims, says [stem cell scientist Hans] Schöler, who reviewed the paper and, as is standard practice at Cell, saw the comments of other reviewers for the journal. At Science, according to the 8 May RIKEN investigative committee’s report, one reviewer spotted the problem with lanes being improperly spliced into gel images. “This figure has been reconstructed,” the RIKEN report quotes from the feedback provided by a Science reviewer. The committee writes that the “lane 3” mentioned by the Science reviewer is probably the lane 3 shown in Figure 1i in the Nature article. The investigative committee report says [co-author Haruko] Obokata told the committee that she did not carefully consider the comments of the Science reviewer.
The entire reports, however, have not been made available. Retraction Watch has obtained the full text of the editor’s cover letter and reviews of the rejected Science paper. The reviews are full of significant questions and doubts about the work, as would be expected in a rejection. We present them here, to fill in some of the gaps and help readers consider how the research eventually made it through peer review: Read the rest of this entry »
The Japan Aerospace Exploration Agency (JAXA) has requested that Science retract a 2006 paper about the makeup of asteroid Itokawa as observed from the spacecraft Hayabusa, the news section of Science reports.
Instead of calibrating their equipment on Earth, the scientists assumed they’d see both magnesium and silicon in the x-ray spectra, and used that assumption to assess the rest of the chemical composition of the asteroid.
We imagine readers of Biomedical Chromatography’s special issue, “Reminiscences of Chang Kee Lim,” did some flipping back and forth when they found the same paper published twice.
Here’s the resulting notice for “Determination of 4-hydroxy-2-nonenal in serum by high-performance liquid chromatography with fluorescence detection after pre-column derivatization using 4-(N,N-dimethylaminosulfonyl)-7-hydrazino-2,1,3-benzoxadiazole”: Read the rest of this entry »
The Japanese endocrinology researcher Shigeaki Kato, with at least 25 retractions to his name, is alleged to have been the ringleader of a scheme to cover up other research misconduct at the University of Tokyo, his former employer, which investigated the activity.
In a stunning and tragic development, a co-author of the now-retracted Nature papers claiming to have found an easy way to create stem cells has committed suicide, according to news reports in Japan.
