Shigeaki Kato, an endocrinology researcher who resigned last year from the University of Tokyo and has retracted five papers, now has five more papers subject to an expression of concern. Here’s the notice in Molecular and Cellular Biology:

Nanotech researcher SK Sahoo notches fifth retraction

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. According to a notice for “Enhanced cellular uptake and in vivo pharmacokinetics of rapamycin loaded cubic phase nanoparticles for cancer therapy” that appears … Continue reading Nanotech researcher SK Sahoo notches fifth retraction

Diabetes paper retracted for “misgrouping errors” that remain under investigation

A group of researchers at the University of Minnesota have retracted a paper in Diabetes for image problems, but exactly what happened is still under investigation. Here’s the notice:

Authors retract already-corrected Nature malaria paper

Nature is retracting a 2010 paper by a team from Princeton and Drexel on the workings of Plasmodium falciparum, which causes malaria in people. How that came about seems to have been a winding road. The article — a research letter — titled “Branched tricarboxylic acid metabolism in Plasmodium falciparum,” came from the Princeton lab … Continue reading Authors retract already-corrected Nature malaria paper

“Conflicts among the authors” force retraction of Talanta paper

Talanta, a journal serving the analytical chemistry community — we’d love to know how the name came to be — has retracted a 2013 article by a group of Indian researchers over an authorship dispute. The paper, “Non-enzymatic electrochemical glucose sensor based on silver/silver oxide nano-rods reinforced with multiwall carbon nanotubes,” appeared in January, with … Continue reading “Conflicts among the authors” force retraction of Talanta paper

Influential Reinhart-Rogoff economics paper suffers spreadsheet error

April showers bring … database errors? The other day, we wrote about two retractions in the Journal of the American College of Cardiology, and another in the American Heart Journal, stemming from database errors. Seems to be catching. The Economist (among other outlets) this week is reporting about a similar nother database glitch — not, … Continue reading Influential Reinhart-Rogoff economics paper suffers spreadsheet error

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

“Highly unethical practices” force four retractions for nanotech researcher

Sanjeeb K. Sahoo, of the Institute of Life Sciences in Bhubaneswar, India, has had four papers retracted from Acta Biomaterialia for what the journal is calling “highly unethical practices.” All four notices say the same thing:

“Way out there” paper claiming to merge physics and biology retracted

A German professor who claims to have developed “a self-consistent field theory which is used to derive at all known interactions of the potential vortex” will have at least two papers retracted, thanks to the scrutiny of a concerned economist. The first retraction has already appeared, in DNA and Cell Biology, for a paper by … Continue reading “Way out there” paper claiming to merge physics and biology retracted

Plague paper partially retracted

Partial retractions — as opposed corrections or the full monty —  are unusual events in scientific publishing. But they appear to come in twos. The journal Infection and Immunity, the work of whose editor, Ferric Fang, is much admired by this blog, has a fascinating example of the breed in its February issue. The article … Continue reading Plague paper partially retracted
