Cell is looking into whether the authors of a widely hailed study published last week claiming to have turned human skin cells into embryonic stem cells manipulated images inappropriately, Retraction Watch has learned.
The potential image problems came to light on PubPeer, a site designed to allow for post-publication peer review. A commenter, identified as Peer1, identified “several examples of image reuse which might be of interest to PubPeer members and readers:” Read the rest of this entry »
Nanotech researcher SK Sahoo, whom as we reported in February lost four papers from Acta Biomaterialia for what the journal called “highly unethical practices,” has actually retracted five papers from that journal.

The Journal of Multivariate Analysis has retracted a paper it was never meant to publish — a problem, it seems, of multivariate analyses.
The article, titled “Regression estimation with locally stationary long-memory errors,” came from a pair of statisticians in Chile, Wildredo Palma and Guillermo Ferreira.
The retracted paper, “Permeability Estimation of a Reservoir Based on Neural Networks Coupled with Genetic Algorithms,” appeared online in August 2011 in Petroleum Science and Technology, a Taylor & Francis journal. According to the liner notes, the paper had been received on January 15, 2010 and accepted a few weeks later. It has been cited once since, according to Thomson Scientific’s Web of Knowledge, by its authors, in a paper published in the same journal.
Meanwhile, in August 2011 the authors (minus one name) also published “Evolving neural network using real coded genetic algorithm for permeability estimation of the reservoir,” in Expert Systems With Applications, an Elsevier title.
Two cancer papers retracted because authors “are unable to guarantee the accuracy of some of the figures”
Denise Egan, of the Institute of Technology Tallaght in Dublin, and colleagues published “In vitro anti-tumour and cyto-selective effects of coumarin-3-carboxylic acid and three of its hydroxylated derivatives, along with their silver-based complexes, using human epithelial carcinoma cell lines” and “A study of the role of apoptotic cell death and cell cycle events mediating the mechanism of action of 6-hydroxycoumarin-3-carboxylatosilver in human malignant hepatic cells” in 2007.
