National University of Singapore official who co-authored Melendez papers won’t be part of investigation

The Alirio Melendez case is likely to become quite complicated, as the National University of Singapore (NUS) looks into about 70 papers by the researcher whose work has already been the subject of a retraction and Expression of Concern. One such wrinkle seemed to have already surfaced when a blog called the Gigamole Diaries pointed out last week … Continue reading National University of Singapore official who co-authored Melendez papers won’t be part of investigation

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

Does a new retraction suggest a glimmer of hope for transparency at the Journal of Neuroscience?

Believe it or not, we look for policies to praise here at Retraction Watch HQ, especially if they mark a change from approaches that we and others have criticized. So we were heartened to read this retraction notice in The Journal of Neuroscience for “Lmx1b-Controlled Isthmic Organizer Is Essential for Development of Midbrain Dopaminergic Neurons:” … Continue reading Does a new retraction suggest a glimmer of hope for transparency at the Journal of Neuroscience?

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

Authors retract chemistry paper after failing to get company’s permission to publish

Two chemists who published a paper earlier this year in Bioconjugate Chemistry have withdrawn it, after their company, Life Technologies, let them know they didn’t have permission to submit the work. The retraction notice reads: Facile Synthesis of Symmetric, Monofunctional Cyanine Dyes for Imaging Applications, by Lai-Qiang Ying and Bruce P. Branchaud, Bioconjugate Chem., 2011, 22 (5), pp 865–869, … Continue reading Authors retract chemistry paper after failing to get company’s permission to publish

Lack of ethical approval leads to JCO retraction

The Retraction Watch category for “lack of IRB approval” as a reason for retraction — a subject we covered in our most recent Lab Times column — is growing. First there were the 90-odd retractions by Joachim Boldt, then three by Australian researchers studying Aussie-rules football players. Now, we learn that the Journal of Clinical … Continue reading Lack of ethical approval leads to JCO retraction

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

Duke sued over Potti case

From the “not terribly surprising” department: Eight patients — or their estates — who enrolled in clinical trials at Duke overseen by Anil Potti and colleagues have sued the university. The 90-page lawsuit, which names Duke, Potti, Potti’s boss Joseph Nevins, CancerGuide Diagnostics (in which Potti and Nevins had an interest), among others, does a thorough job of documenting … Continue reading Duke sued over Potti case

Anil Potti failed to disclose corporate ties in yet-to-be-retracted JAMA papers

Anil Potti, the former cancer researcher whose work has become the subject of intense scrutiny that has already led to the retraction of five papers, didn’t tell the Journal of the American Medical Association (JAMA) about two very relevant corporate relationships he had when he published papers there, Retraction Watch has learned. JAMA has published two papers by … Continue reading Anil Potti failed to disclose corporate ties in yet-to-be-retracted JAMA papers

Montreal Heart Institute researcher dismissed following two retractions for image manipulation

A Montreal Heart Institute researcher who retracted two papers less than a month ago has been fired from his post. Zhiguo Wang, who had been funded by the Canadian Institute of Health Research and the Canadian Diabetes Association, studied the genes linked to heart rhythm abnormalities, among other subjects. Wang also has an appointment at the University … Continue reading Montreal Heart Institute researcher dismissed following two retractions for image manipulation
