Second expression of concern appears for chemistry group under institutional review
The journal Chemical Science has issued an expression of concern over a 2012 article by a pair of Texas researchers whose “unclick reaction” work has been under scrutiny by their institution.
The article, “Homonuclear bond activation using a stable N,N-diamidocarbene,” was written by Kelly M. Wiggins and Christopher W. Bielawski, of UT Austin. It’s the second EoC that we know of for a paper by Wiggins and Bielawski. We covered a previous one, from Science, that appeared in June.

Shigeaki Kato up to 33 retractions, with five papers cited a total of 450 times

Former University of Tokyo researcher Shigeaki Kato continues to put big numbers on the board.
Last month, we reported on his 26th, 27th, and 28th retractions, all in Nature Cell Biology and cited close to 700 times. Yesterday, EMBO Journal and EMBO Reports published a total of five more retractions for the endocrinology researcher, who resigned from the university in 2012 following investigations found he had faked images.
Here’s the notice for “A cell cycle-dependent co-repressor mediates photoreceptor cell-specific nuclear receptor function:” Continue reading Shigeaki Kato up to 33 retractions, with five papers cited a total of 450 times

Nature issues Expression of Concern for paper by author who threatened to sue Retraction Watch

Nature has issued an Expression of Concern for a paper co-authored by a scientist who threatened to sue us last year for writing about another Expression of Concern for one of his other papers.

Weekend reads: Former vice chancellor sent to jail for plagiarism; peer reviewers getting tired
This week, we published a feature in Nature on how some researchers are gaming peer review systems to review their own papers. Here’s what was happening elsewhere:
Plagiarism charge bites authors of oral pain paper
The Journal of International Oral Health has retracted a 2014 paper on dental pain by a group from India. Although the ostensible reason was plagiarism, we wonder if the offending authors might gone a bit further.
The article, “Sniffing out pain: An in vivo intranasal study of analgesic efficacy,” purported to be a study of 20 patients receiving different therapies for emergency oral pain. It has yet to be cited, according to Thomson Scientific’s Web of Knowledge. Here’s the abstract: Continue reading Plagiarism charge bites authors of oral pain paper
