Paper with “missing or placed wrongly” controls retracted because there’s “no editorial mechanism to review the errors”

Two researchers from Singapore are retracting a paper that included errors in three figures because there’s apparently no way to fix the mistakes and have the new work reviewed. Here’s the notice for “Host-dependent effects of the 3′ untranslated region of turnip crinkle virus RNA on accumulation in Hibiscus and Arabidopsis,” by Weimin Li and … Continue reading Paper with “missing or placed wrongly” controls retracted because there’s “no editorial mechanism to review the errors”

And then there were eight: Three more retractions for Alirio Melendez, all in the Journal of Immunology

Alirio Melendez, who has already retracted five papers and was found by one of his former universities to have committed misconduct on more than 20, has three more retractions. Here’s the notice for “Antisense Knockdown of Sphingosine Kinase 1 in Human Macrophages Inhibits C5a Receptor-Dependent Signal Transduction, Ca2+ Signals, Enzyme Release, Cytokine Production, and Chemotaxis,” … Continue reading And then there were eight: Three more retractions for Alirio Melendez, all in the Journal of Immunology

Magnets paper fails to stick as plagiarism leads to retraction

A group engineers from Iran and Singapore have been forced to retract a paper in the Journal of Magnetism and Magnetic Materials after the article was found to contain incidents of plagiarism. The article, “Magnetic properties of iron-based soft magnetic composites with MgO coating obtained by sol–gel method,” appeared in April 2010. Sometime later (we’re … Continue reading Magnets paper fails to stick as plagiarism leads to retraction

NUS: Melendez committed “serious scientific misconduct,” but don’t expect to get any details

Science issues Expression of Concern over already-corrected Melendez-Puneet paper

Two weeks ago, we posted on a Nature Immunology retraction by a group that had earlier published a correction to figures in a Science paper. At the time, many readers suggested there was more to this story — and we had the same hunch. Turns out those hunches were right. Today, Science issued an “Expression … Continue reading Science issues Expression of Concern over already-corrected Melendez-Puneet paper
