Carrion, my wayward son: Vulture paper from Spanish researcher suspected of misconduct retracted

Back in March, we wrote about the doubts that had emerged in Spain about the work of a prominent local veterinary scientist, Jesús Ángel Lemus, suspected of being a data fabricator and inventor of co-authors (one in particular). We hadn’t heard anything since about Lemus — who specialized in the effects of environmental toxins on … Continue reading Carrion, my wayward son: Vulture paper from Spanish researcher suspected of misconduct retracted

20 more retractions for scientist who made up email addresses so he could review his own papers

Hyung-In Moon, the South Korean plant compound researcher who came up with fake email addresses so that he could do his own peer review, has retracted twenty more papers, all in Immunopharmacology and Immunotoxicology, an Informa Healthcare title. Here are the papers:

Authors retract prostate cancer-grape seed compound paper for figure presentation error

University of Alabama researchers have retracted a paper claiming that a grape skin seed compound might have anti-prostate cancer effects. Here’s the notice for “Proanthocyanidins from grape seeds inhibit expression of matrix metalloproteinases in human prostate carcinoma cells, which is associated with the inhibition of activation of MAPK and NFκB”:

ORI finds Parkinson’s-pesticides researcher guilty of faking data; two papers to be retracted

The U.S. Office of Research Integrity (ORI) has found that a neuroscientist who studied the effects of pesticides on a mouse model of Parkinson’s disease made up data. As The Scientist reported on Friday, the ORI found that Mona Thiruchelvam faked cell counts in two grant applications and a number of papers that claimed to … Continue reading ORI finds Parkinson’s-pesticides researcher guilty of faking data; two papers to be retracted

Reverse tissue engineering: data reuse causes retractions of three papers from German organ researchers

The body count has reached three for a group of German tissue engineers who appear to have cloned their data in many of their publications. Tissue Engineering Part A has retracted one of the papers from the investigators, titled “Clinically established hemostatic scaffold (tissue fleece) as biomatrix in tissue- and organ-engineering research,” which was published … Continue reading Reverse tissue engineering: data reuse causes retractions of three papers from German organ researchers

Resveratrol researcher Das in video: Yes, I manipulated images, but only because the journals asked me to

Dipak Das, who until earlier this year ran a high-profile cardiovascular research center at the University of Connecticut, has recorded a slick looking video defense against allegations that he cooked data and manipulated images in scores of published studies, 12 of which have been retracted to date. Das, who was hit with a 60,000 pages … Continue reading Resveratrol researcher Das in video: Yes, I manipulated images, but only because the journals asked me to

Biologists delete paper from literature after realizing they’d deleted too many genes

Researchers deleted more genes than they bargained for in a Drosophila strain, a mistake that resulted in a retraction of a paper from 2007. Ron Wides, a biologist specializing in pattern development at Bar-Ilan University, Israel, and colleagues have retracted a paper published in Mechanisms of Development after his lab found that their technique to delete the … Continue reading Biologists delete paper from literature after realizing they’d deleted too many genes

FASEB J retracts 15-year-old study after author comes forward, but universities decline to investigate

The FASEB Journal — FASEB stands for the Federation of American Societies for Experimental Biology — is retracting a 15-year-old paper without the consent of all of the authors, despite what seem like valiant attempts to figure out exactly what went wrong. Here’s the notice for the University of Bern-University of Urbino paper:

Why retraction notices matter: Group’s repeated misuse of figures gets different play from five journals

For some journals, thorough retraction notices are the rule — and, when misconduct is involved, the price authors pay for abusing the trust of the editors and the readers. Others seem to take a more casual approach. Guess which we think is best. Consider the case of a group of researchers in China led by … Continue reading Why retraction notices matter: Group’s repeated misuse of figures gets different play from five journals

Assay come, assay go: Corporate takeover leads to retraction of device analysis

A group of hematology researchers in Canada lost a publication to the merger of two medical device makers, after the acquiring company apparently decided not to pursue marketing the product in question. An April 23 retraction notice in the International Journal of Laboratory Hematology about the article, “Enhanced flagging and improved clinical sensitivity on the new … Continue reading Assay come, assay go: Corporate takeover leads to retraction of device analysis
