A group of dentistry researchers in Japan, whose work on stem cells has been the subject of an institutional investigation, have now lost two papers in PLOS ONE for image problems. The authors, from Aichi Gakuin University in Nagoya, were led by Makio Mogi, a medicinal biochemist at the school. Mogi asked for at least … Continue reading Stem cell researchers have papers retracted for image manipulation
A researcher in India is up to five retractions, by our count, for problematic data and image issues. The latest retractions involve articles published in 2008 and 2013 in the journal Life Sciences. The last author on the papers is Yogeshwer Shukla, of the Council of Scientific and Industrial Research, about whom we have previously … Continue reading Cancer researcher up to five retractions

Yes, you read that headline right. In a new preprint posted to bioRxiv, image sleuths scanned hundreds of papers published over a seven-year period in Molecular and Cellular Biology (MCB), published by the American Society for Microbiology (ASM). The researchers — Arturo Casadevall of Johns Hopkins University, Elisabeth Bik of uBiome, Ferric Fang of the … Continue reading 35,000 papers may need to be retracted for image doctoring, says new paper
Title: Effects of microRNA-223 on morphine analgesic tolerance by targeting NLRP3 in a rat model of neuropathic pain What Caught Our Attention: Usually, an Expression of Concern (EOC) offers general language about “concerns regarding the validity of the data” or “concerns regarding the integrity of the study.” Here the language is anything but, saying that … Continue reading Caught Our Notice: 54 problems in three scientific images equals one expression of concern
Titles: 1) Angiopoietin-Like 4 Confers Resistance to Hypoxia/Serum Deprivation-Induced Apoptosis through PI3K/Akt and ERK1/2 Signaling Pathways in Mesenchymal Stem Cells 2) Novel Mechanism of Inhibition of Dendritic Cells Maturation by Mesenchymal Stem Cells via Interleukin-10 and the JAK1/STAT3 Signaling Pathway What Caught Our Attention: In the span of 48 hours, PLOS ONE retracted two papers … Continue reading Caught Our Notice: Duplicates, errors prompt two retractions for same author
Title: A mitochondrial ferredoxin is essential for biogenesis of cellular iron-sulfur proteins What Caught Our Attention: Here’s a cut-and-paste issue that gave us pause. The authors of an 18-year-old paper in PNAS corrected it after realizing some bands in a figure were duplicated (an issue raised on PubPeer one year ago). It turns out, the … Continue reading Caught Our Notice: “The first author cut the thermoprinter paper printout into pieces and reassembled them”
Researchers at a prominent Japanese university have retracted a 2015 paper in Science, after an investigation uncovered image falsification and fabrication. Last September, the University of Tokyo began an investigation of seven papers from the lab of cell biologist Yoshinori Watanabe after receiving anonymous allegations. In May 2017, the university determined that five papers contained falsified … Continue reading Authors retract Science paper after investigation reveals manipulated images
Science Signaling has issued an expression of concern for a 2016 paper, citing an institutional investigation into image manipulation. According to a spokesperson for the journal, the corresponding author, Tanya Kalin, became concerned that two images in the paper had been manipulated. Kalin then notified the research integrity officer at Cincinnati Children’s Hospital Medical Center, … Continue reading Science journal flags cancer paper under investigation for image manipulation
A diabetes researcher who sued a publisher to protect several papers from being retracted recently received his 13th, in a prestigious gastroenterology journal. Mario Saad, based at the University of Campinas in São Paulo, Brazil, has had a string of retractions over the past few years, including four in Diabetes after he lost a legal … Continue reading Diabetes researcher who sued to prevent retractions now has 13
