Three authors have been banned from journals published by IGM Publication, including the Journal of Medical Science and Clinical Research. The ban — a relatively infrequent occurrence in publishing — comes after the publisher removed a 2014 article that seems to have merely changed the title and authors of a 2013 article from another journal. When … Continue reading Publisher bans authors for apparent plagiarism
Clinical studies that eventually get retracted are originally published with significantly more errors than non-retracted trials from the same journal, according to a new study in BMJ. The authors actually called the errors “discrepancies” — for example, mathematical mistakes such as incorrect percentages of patients in a subgroup, contradictory results, or statistical errors. The study doesn’t predict … Continue reading Can you spot the signs of retraction? Just count the errors, says a new study
The Indian Journal of Dermatology has retracted a paper on the potential genetic markers of psoriasis that had already been retracted once for redundant publication. The journal is chalking it up to an “administrative error” that caused it to publish a paper that had already appeared in two other outlets. According to one of the … Continue reading Skin study retracted twice in triple publication rub
Thanks to some eagle-eyed readers, we’ve been alerted to some corrections for high profile stem cell scientist Jacob Hanna that we had missed, bringing our count to one retraction and 13 errata on 10 papers. The problems in the work range from duplications of images, to inadvertent deletions in figures, to failures by his co-authors to disclose … Continue reading Stem cell researcher Jacob Hanna’s correction count updated to 10
A nearly ten-year-long series of investigations into a pair of plant physiologists who received millions in funding from the U.S. National Science Foundation has resulted in debarments of less than two years for each of the researchers. The NSF Office of Inspector General recently posted its close-out report on its decision and a review of … Continue reading NSF investigation of high-profile plant retractions ends in two debarments
A correction to a correction is the latest problem for highly cited researcher Jacob Hanna. The stem cell scientist — whose high-profile work has received scrutiny over the past year — has amended an earlier correction notice after a reader spotted an inadvertent “mistake.” We reported on the original correction, to the 2009 Cell Stem Cell paper “Metastable Pluripotent States in NOD-Mouse-Derived ESCs,” in July. The … Continue reading A correction to a correction for stem cell researcher Jacob Hanna
An investigation into the work of Olivier Voinnet by The EMBO Journal has led to another two retractions and three more corrections for the high-profile plant scientist, now suspended from the CNRS for two years. According to the authors, Voinnet was responsible for some of the errors; all papers have been questioned on PubPeer. The EMBO J, … Continue reading EMBO investigation yields two more retractions and three corrections for Voinnet
A group of researchers conducted a clinical trial on hundreds of hypertensive patients. Then, they published the results…six times. The “nearly identical” papers came to our attention via a retraction in Inflammation. Editor in chief Bruce Cronstein explained how he learned of the mass duplication: The editors were contacted en masse by somebody doing a Cochrane Review … Continue reading “Exactly the same clinical study” published six times
A pair of papers about the risks of titanium dioxide nanoparticles that share many of the same authors has been retracted from a toxicology journal following an investigation at Soochow University in China. Particle and Fibre Toxicology is retracting the papers for problems with the statistical methods and missing data, as well as for sharing figures. … Continue reading Trouble with data proves toxic for a pair of toxicology papers
Biotechnology Letters has retracted a paper on a new gene delivery technique due to “the deliberate and fraudulent use of data in the paper that had previously appeared in other papers of these two authors.” The journal’s Editor in Chief Colin Ratledge told us that someone tipped him off that one of the authors, University of Kalyani microbiologist Keka Sarkar, … Continue reading Gold nanoparticle paper crushed by “deliberate and fraudulent use of data”
