Fifth Alirio Melendez retraction offers clues about University of Glasgow misconduct findings

A new retraction — his fifth — in the Journal of Immunology for Alirio Melendez, formerly of the National University of Singapore, the University of Glasgow, and the University of Liverpool, sheds some light on the results of an investigation by one of the universities. Last month, a Glasgow spokesperson told Nature that the university’s … Continue reading Fifth Alirio Melendez retraction offers clues about University of Glasgow misconduct findings

Retraction number four appears in PNAS for work of Alirio Melendez, who has resigned post at U Liverpool

Alirio Melendez, who has had three of his papers retracted amidst suspicions about 70, has had another one retracted, this one in the Proceedings of the National Academy of Sciences (PNAS). And he has also resigned from his post at the University of Liverpool, we have just learned. Here’s the notice:

Third retraction arrives for Alirio Melendez, this one in the Journal of Cellular Physiology

Alirio Melendez, the former National University of Singapore researcher who has already retracted two papers in the midst of an investigation into about 70 of his publications, has had a third retracted a third. Here’s the notice from the Journal of Cellular Physiology:

Second retraction arrives in Alirio Melendez case

Alirio Melendez, whose former employer, the National University of Singapore, is investigating about 70 of his papers, has retracted a second study. Here’s the notice for the 2010 Journal of Molecular Cell Biology paper, “Sphingosine-1-phosphate mediates proliferation maintaining the multipotency of human Adult Bone Marrow and Adipose Tissue-derived Stem Cells:”

70 papers by Alirio Melendez under investigation: report

The National University of Singapore (NUS) is reviewing about 70 papers by Alirio Melendez, a once-promising researcher whom, as we’ve reported, has been forced to retract a paper in Nature Immunology and has another paper in Science subject to an Expression of Concern. The Straits Times, which reported the NUS investigation this weekend, says Melendez’ former team is cooperating: In … Continue reading 70 papers by Alirio Melendez under investigation: report

Science issues Expression of Concern over already-corrected Melendez-Puneet paper

Two weeks ago, we posted on a Nature Immunology retraction by a group that had earlier published a correction to figures in a Science paper. At the time, many readers suggested there was more to this story — and we had the same hunch. Turns out those hunches were right. Today, Science issued an “Expression … Continue reading Science issues Expression of Concern over already-corrected Melendez-Puneet paper

Group retracts Nature Immunology paper for figure irregularities after posting a correction to Science

We’re following the case of a group that recently retracted a Nature Immunology paper for figure irregularities, soon after being forced to correct images in a Science paper for similar reasons. The Nature Immunology paper, “The helminth product ES-62 protects against septic shock via Toll-like receptor 4–dependent autophagosomal degradation of the adaptor MyD88,” has been … Continue reading Group retracts Nature Immunology paper for figure irregularities after posting a correction to Science

Obfuscation watch: Self-plagiarism (we think) leads to retraction of nanorod paper in Applied Physics Letters

C. P. Snow famously bemoaned the gulf between science and the humanities. The following retraction might be the sort of thing that would have given the physicist-cum-author fits for its estrangement from the English language. Writing in the latest issue of Applied Physics Letters, a team from China Singapore and MIT appear to be confessing … Continue reading Obfuscation watch: Self-plagiarism (we think) leads to retraction of nanorod paper in Applied Physics Letters

Leading cancer scientist retracts two papers, one 14 years old, but journal won’t say why

One of the world’s leading cancer researchers, Axel Ullrich of Germany, has retracted two papers published in the Journal of Biological Chemistry. Ullrich, director of microbiology at the Max Planck Institute of Biochemistry, has been a central figure in many groundbreaking discoveries, from the development of genetically engineered insulin to the identification of the breast … Continue reading Leading cancer scientist retracts two papers, one 14 years old, but journal won’t say why
