University of Maryland researchers notch second retraction

jbc 42514Two researchers at the University of Maryland who retracted a paper earlier this year for a duplicated figure have withdrawn another, this time for unknown reasons.

The Journal of Biological Chemistry (JBC) paper has been cited 16 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice, for “Hsp90 Interaction with INrf2(Keap1) Mediates Stress-induced Nrf2 Activation,” which is unfortunately a return to the JBC’s opacity: Continue reading University of Maryland researchers notch second retraction

Wrong cell line leads to retraction of kidney cancer study

plosoneA group of authors in China has retracted their December 2013 paper in PLoS ONE after realizing that they’d been studying the wrong cells.

Over the past week, there have been a number of comments on PubPeer — a site of which we’re big fans — about a 2007 paper in Oncogene.

The comments suggested that the figures in the paper had problems. Some bands seemed to be duplicated, and one of the images looked very much like that of another paper.

Then, today, first author Eriko Suzuki left this comment: Continue reading Brutal honesty: Author takes to PubPeer to announce retraction — and tells us she’ll lose PhD, professorship

Heart study retracted because it was submitted without permission of most of the authors

clincardcoverA group of authors in South Korea has lost their 2012 paper in Clinical Cardiology because, well, they weren’t a group after all.

The paper, “Correlation of Electrocardiographic Changes and Myocardial Fibrosis in Patients With Hypertrophic Cardiomyopathy Detected by Cardiac Magnetic Resonance Imaging,” came from corresponding author of Konkuk University School of Medicine in Seoul, and a half-dozen colleagues. At least, that’s what the manuscript said.

But according to the retraction notice, Yang had nothing to do with the paper — nor did five other co-authors. Continue reading Heart study retracted because it was submitted without permission of most of the authors

Harvard and the Brigham investigating leading heart group for “compromised” data

circulationcoverCirculation has retracted a 2012 study by a group of Harvard heart specialists over concerns of corrupt data, and the university is investigating. The group was led by Piero Anversa, a leading cardiologist, and Joseph Loscalzo — who will be familiar to readers of Circulation as the editor in chief of that journal. (Anversa’s also on the editorial board).

Co-author of retracted conspiracy ideation-climate skepticism paper addresses apparent contradictions

Lewandowsky
Lewandowsky

We — and others — have been scratching our heads about the real reasons for the formal retraction on March 21 of a Frontiers in Psychology paper since the journal issued a statement on the subject on Friday that seemed to contradict the retraction notice and that certainly differed from accounts on some blogs. Today, we learned a few more details about what happened in the year between when the paper was provisionally removed and then formally retracted from a post by Stephan Lewandowsky, one of the co-authors of the paper.

The March 21 statement, writes Lewandowsky, Continue reading Co-author of retracted conspiracy ideation-climate skepticism paper addresses apparent contradictions

Do you see what I see? Heart imaging journal yanks cardiac study for plagiarism
