When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper

The journal Colloids and Surfaces B: Biointerfaces has retracted a 2011 paper by a group of researchers in India who misappropriated — and then manhandled — a pair of images from a previously published article by other scientists. The paper, “Synthesis and characterization of chitosan and grape polyphenols stabilized palladium nanoparticles and their antibacterial activity,” … Continue reading When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper

Figure error forces retraction of transgenic chickpea paper

The humble chickpea has become one of the world’s most promising cash crops, so it’s no surprise that efforts are underway to make it even more humble, er, profitable, through genetic manipulation. But one group of scientists made hummus out of their approach when they botched what evidently was a key element of a figure … Continue reading Figure error forces retraction of transgenic chickpea paper

That face rings a bell, but where have I published it before?

Irony alert: If you’re going to write a paper about face recognition technology, well, do we really need to go on? A group of researchers in Wuhan, China, evidently didn’t quite realize they were walking into a ridicule trap when they agreed to have their paper, “Face Recognition with Learning-based Descriptor,” published in IERI Procedia. … Continue reading That face rings a bell, but where have I published it before?

University of Utah finds former faculty member guilty of misconduct because of “reckless disregard”

Since last May, we’ve been reporting on a case at the University of Utah involving two retractions and two corrections. When the story first broke, the lab blamed a former worker for inappropriately removing data from the premises, and the university has been investigating. Last month, we reported that Ivana De Domenico, the junior faculty … Continue reading University of Utah finds former faculty member guilty of misconduct because of “reckless disregard”

Leading immunologist retracts paper that duplicated 2004 PNAS study

University of Glasgow professor Foo Yew “Eddy” Liew, a Fellow of the Royal Society, has retracted a paper in Cellular Immunology because it duplicated one of his earlier papers in the Proceedings of the National Academy of Sciences (PNAS). Here’s the notice for “Expression and function of Toll-like receptor on T cells:”

Ants in the past: Journal pulls insect-global warming paper after questions arise over results

A group of ecologists in Germany who published a paper on the potential impact of global warming on ants in the Harz Mountains — northern Germany’s highest range — have retracted the paper after becoming, well, a bit antsy about the validity of their findings. The article, “Diversity of ants across an altitudinal gradient in … Continue reading Ants in the past: Journal pulls insect-global warming paper after questions arise over results

Retraction of 19-year-old Nature paper reveals hidden cameras, lab break-in, evidence tampering

We’ve often found that when some authors refuse to sign retraction notices, there’s a much bigger story than terse notices let on. And a retraction in this week’s Nature of a 19-year-old paper is a shining example of that. Here’s the brief notice for “Oligosaccharide ligands for NKR-P1 protein activate NK cells and cytotoxicity,” a … Continue reading Retraction of 19-year-old Nature paper reveals hidden cameras, lab break-in, evidence tampering

Paper on vulvar tumor retracted. Why? Journal won’t say

Cancer of the vulva may well be a topic most people do not want to discuss. But we wish the Journal of Lower Genital Tract Disease (the official journal of several societies, including the American Society for Colposcopy and Cervical Pathology, the Australian Society for Colposcopy and Cervical Pathology and the Society of Canadian Colposcopists) had … Continue reading Paper on vulvar tumor retracted. Why? Journal won’t say

Five Kato papers subject to an expression of concern, plus, a statute of limitations on correcting the literature?

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
