Doing the right thing: Physicists retract paper after becoming aware of “a fundamental error”

prl-bannerThe authors of a paper in Physical Review Letters have retracted it, after another researcher pointed out a mistake.

F. Sattin and D.F. Escande write in the notice for “Alfvénic Propagation: A Key to Nonlocal Effects in Magnetized Plasmas” (which is behind a paywall) that after the paper was published, they “we became aware of a fundamental error in the normalization of our equations.” Excerpt: Continue reading Doing the right thing: Physicists retract paper after becoming aware of “a fundamental error”

Stem cell researcher in Korea up to half a dozen retractions

stem cellsAlmost two years ago, we brought you — with the help of Trevor Stokes — the story of a stem cell researcher in Korea whose publication record, and career, unraveled after evidence of image manipulation surfaced in her work.

We’ve reported on four retractions, all in Antioxidants & Redox Signaling, by Soo-Kyung Kang, formerly of Seoul National University resulting from the efforts of a whistleblower. There has been another in Human Gene Therapy: Continue reading Stem cell researcher in Korea up to half a dozen retractions

Heart study retracted because it was submitted without permission of most of the authors

clincardcoverA group of authors in South Korea has lost their 2012 paper in Clinical Cardiology because, well, they weren’t a group after all.

The paper, “Correlation of Electrocardiographic Changes and Myocardial Fibrosis in Patients With Hypertrophic Cardiomyopathy Detected by Cardiac Magnetic Resonance Imaging,” came from corresponding author of Konkuk University School of Medicine in Seoul, and a half-dozen colleagues. At least, that’s what the manuscript said.

But according to the retraction notice, Yang had nothing to do with the paper — nor did five other co-authors. Continue reading Heart study retracted because it was submitted without permission of most of the authors

Data highjinx forces retraction of tumor paper in JBC

jbccover414The Journal of Biological Chemistry has an illuminating retraction notice — we’re happy to be able to say — about a 2001 article from a group of researchers at the National University of Singapore.

The paper, “Intracellular acidification triggered by mitochondrial-derived hydrogen peroxide is an effector mechanism for drug-induced apoptosis in tumor cells,” was written by Jayshree L. Hirpara, Marie-Véronique Clément and Shazib Pervaiz.

It has has been cited 110 times, according to Thomson Scientific’s Web of Knowledge. According to the retraction notice: Continue reading Data highjinx forces retraction of tumor paper in JBC

Expression of Concern tarnishes copper oxide paper

jmcacoverArticles, like lawn furniture, aren’t supposed to rust after just two months. But the Journal of Materials Chemistry A has issued an Expression of Concern for a February 2014 paper by a group of chemists from India over possible problems with several figures in the article.

The paper, “Hierarchically macro/mesostructured porous copper oxide: Facile synthesis, Characterization, Catalytic performance and Electrochemical study of mesoporous copper oxide monoliths,” was written by Gowhar Ahmad Naikoo, of the department of chemistry at Dr. Hari Singh Gour Central University, in Sagar, and two colleagues. It purported to find that:

A group of pharmacologists in Japan has retracted their 2012 article in the International Journal of Pharmaceutics for plagiarism. But not, they note, for any other reason.

The article, “Suppression of efflux transporters in the intestines of endotoxin-treated rats,” came from researchers in the Department of Drug Absorption and Pharmacokinetics in the School of Pharmacy at Tokyo University of Pharmacy and Life Sciences. It has been cited once, according to Thomson Scientific’s Web of Knowledge.

Multiple data errors force retraction of paper about preemies

adcfnA group of neonatal researchers in Caen has lost their 2013 review article in Archives of Disease in Childhood Fetal & Neonatal Edition for a variety of problems with their analysis of the data.

The article was titled “NIDCAP in preterm infants and the neurodevelopmental effect in the first 2 years,” and its first author was Laura Fazilleau of University Hospital Côte de Nacre.

According to the abstract: Continue reading Multiple data errors force retraction of paper about preemies

NIH/Harvard team loses aging study to manipulated data

agecoverAge has retracted a 2012 article by a group of scientists from the National Institutes of Health and Brigham and Women’s Hospital in Boston after an NIH inquiry turned up evidence of data manipulation in the work.

The article, “Aging decreases rate of docosahexaenoic acid synthesis-secretion from circulating unesterified α-linolenic acid by rat liver,” came from the lab of Stanley Rapoport, chief of the brain physiology and metabolism section of the National Institute on Aging.

As the abstract explained: Continue reading NIH/Harvard team loses aging study to manipulated data

How common is scientific misconduct in Nigeria?

nigeriaWe’ve only covered one retraction from Nigeria. But as we’ve often noted, retraction rates don’t necessarily correlate with rates of problematic research, so the low number doesn’t really answer the question in this post’s title.

Lucky for us, a group of authors have started publishing surveys of Nigerian scientists on the subject. In a new such survey published in BMC Medical Ethics, Patrick I. Okonta and Theresa Rossouw asked 150 researchers to fill out a questionnaire during a scientific conference in 2010. Most of them — 133 — complied. Their findings?
