Two papers on “novel techniques” have been retracted with what is unfortunately a very non-novel technique: an odd notice and silence when we asked for comment.
Here’s the explanation for retraction of “A novel approach to treat residual peridevice leakage after left-atrial appendage closure,” by Wunderlich N, Wilson N, and Sievert H: Continue reading Author squabble sinks cardiology papers

Retractions have arrived in the case of Peter Nijkamp, a leading Dutch economist accused of duplication and plagiarism. The Review of Economic Analysis has removed two of Nijkamp’s articles for self-plagiarism.
According to the NRC Handelsblad website (courtesy of Google translate):
The affair university economics professor Peter Nijkamp and his PhD student Karima Kourtit has escalated. The editors of the journal Review of Economic Analysis (RoEA) appears to have withdrawn because of self-plagiarism two scientific articles (reuse your own work earlier without acknowledgment), NRC Handelsblad discovered last week at the RoEA website.
The website reports that “significant parts” of the reclusive articles have appeared in other publications Nijkamp and Nijkamp / Kourtit, “without reference orderly” earlier. It involves work Nijkamp alone and work of VU economist Frank Bruinsma with Nijkamp and Kourtit.

A significant chapter of the nearly six-month saga of the STAP stem cell controversy has come to an end, with Nature running retraction notices for the two papers involved. The journal has also published an editorial about the case that’s worth a read.
The retractions for “Bidirectional developmental potential in reprogrammed cells with acquired pluripotency” and “Stimulus-triggered fate conversion of somatic cells into pluripotency” both read: Continue reading STAP stem cell papers officially retracted as Nature argues peer review couldn’t have detected fatal problems

Neil Perkins, in whose lab Barré was a postdoc, and Olivier Coqueret, in whose lab he did his PhD, tell Retraction Watch: Continue reading Geneticist retracting four papers for “significant problems”
Retraction Watch readers may have noticed that we often cover retractions long before they appear in PubMed, the gold standard database for the life sciences literature. (In fact, we’ve taken to leaving comments on papers in PubMed Commons about retractions that haven’t been linked to their original abstracts yet.)
This can be an issue, because so many scientists use PubMed to find relevant literature. It may even contribute to the well-documented phenomenon of researchers citing retracted papers as if they hadn’t been retracted.
Until now, no one had quantified the time lag. In a new study, Evelynne Decullier, Laure Huot, and Hervé Maisonneuve — who have published on retractions before — looked at 237 retractions published in 2008. Their findings? Continue reading Some retractions take three years to show up on PubMed: Study
