Heart repair study retraction marks second for Mercer University researcher

Authors of a study on cardiac repair after heart attack are retracting it from Basic Research in Cardiology because they used “the same samples… to represent two distinct groups on two occasions.” We find the language of the retraction somewhat confusing, but to the best of our understanding it means that they compared apples to … Continue reading Heart repair study retraction marks second for Mercer University researcher

“The first author assumes all responsibility:” Malaria vaccine article retracted for image manipulation

Authors of a 2012 article in Infection and Immunity investigating a malaria vaccine strategy are retracting it because it “contains several images that do not accurately reflect the experimental data.” The paper, “Fine Specificity of Plasmodium vivax Duffy Binding Protein Binding Engagement of the Duffy Antigen on Human Erythrocytes,” has been cited 9 times, according to Thomson … Continue reading “The first author assumes all responsibility:” Malaria vaccine article retracted for image manipulation

Biology team with two retractions now correcting references to nixed papers

A team of biologists that retracted two papers after being “unable to replicate some of the results obtained by the first author of the paper” has now issued a correction to fix references to the two sunk publications. The corrected paper is a review in the Journal of Virology — known there as a Gem — … Continue reading Biology team with two retractions now correcting references to nixed papers

Cancer team loses two papers for image manipulation

A team spread across multiple institutions in China and McGill University in Canada has retracted two cancer papers over “inaccurate and inappropriately processed Western Blots.” Some of the figures were also reused between the two articles, both in Biochimica et Biophysica Acta General Subjects. The articles both tested the cancer-fighting properties of a derivative of … Continue reading Cancer team loses two papers for image manipulation

Teflon toxicity paper fails to stick

An advanced online paper on prenatal toxicity of perfluorooctanoic acid (PFOA), an industrial chemical used to make waterproof coatings and Teflon, is being retracted due to “some minor errors.” High blood levels of PFOA have been tied to kidney disease in humans, as well as several cancers in animal models. The majority of the U.S. … Continue reading Teflon toxicity paper fails to stick

Former Columbia postdoc faked Alzheimer’s research in Cell and Nature

Ryousuke Fujita, a former Columbia University postdoc who admitted to having faked the findings of a 2011 Cell paper in a retraction notice last year, also faked the results of a 2013 Nature paper, according to a new report from the Office of Research Integrity (ORI). Fujita’s work, in conjunction with Asa Abeliovich, was widely hailed … Continue reading Former Columbia postdoc faked Alzheimer’s research in Cell and Nature

Cancer Cell issues big correction over “incorrectly cropped” figures, other issues

A 2014 Cancer Cell paper became the subject of an erratum in January 2015, shortly after PubPeer members began criticizing the data. However, many issues brought up by commenters weren’t addressed in the correction notice, including a figure that might be two experiments spliced together to look like one. The paper, led by Guido Franzoso at Imperial College … Continue reading Cancer Cell issues big correction over “incorrectly cropped” figures, other issues

Cell biologists in South Korea retract two papers

A group of researchers at two universities in South Korea have retracted two cell biology papers featuring retinoic acid. The most recent retraction appears in the Journal of Biological Chemistry. Although, in typical JBC fashion, the reason for it is anyone’s guess. Here’s the unhelpful notice for “ASXL1 represses retinoic acid receptor-mediated transcription through associating … Continue reading Cell biologists in South Korea retract two papers

PLoS ONE mega-correction, but no retraction, for researcher who sued diabetes journal

PLoS ONE has just issued a 12-figure correction on a paper by Mario A. Saad, who sued the American Diabetes Association unsuccessfully in an attempt to prevent it from retracting four papers in its flagship journal Diabetes. The corrections include taking out Western blots copied from another Saad paper, as well as several figures where the bands … Continue reading PLoS ONE mega-correction, but no retraction, for researcher who sued diabetes journal
