PNAS retracts two papers on osmolytes after researchers discover crucial measurement errors

A good carpenter never blames his tools. But for scientists, sometimes machines do go bad–with disastrous results. Consider the following:

The Proceedings of the National Academy of Sciences has retracted two papers by researchers in the United Kingdom and the United States after the scientists learned that their results were based largely on a problem with their highly sensitive instruments.

Heart study pulled after production glitch leads to duplicate publication

On reflection, that headline pretty much says it all. But for those readers who took the time to click on the link, here’s the rest of it.

The journal Heart, a title of the BMJ group, has retracted a paper that it published twice: Continue reading Heart study pulled after production glitch leads to duplicate publication

Neigh: Journal retracts brief endangered horse paper for mysterious reasons

Przewalski's Horse, by Jeff Kubina via Wikimedia http://bit.ly/uVr8Ng

Is retracting a paper like shutting the barn door after the horses have bolted?

Sadly, that’s a more apt metaphor than we’d like for a retraction in Equine Veterinary Journal of a short paper about efforts to save Przewalski’s horses, an endangered species closely related to domestic horses. Here’s the notice: Continue reading Neigh: Journal retracts brief endangered horse paper for mysterious reasons

Corrections in PLoS One, Nature Medicine for Zhiguo Wang, and details about Montreal Heart Institute investigation

PLoS One and Nature Medicine have issued corrections for papers by Zhiguo Wang, the former Montreal Heart Institute researcher who resigned in September following an investigation into image manipulation in his lab. 

In September, PLoS One told us that they were investigating the paper. Here’s the text of the correction for “Transcriptional and Post-Transcriptional Mechanisms for Oncogenic Overexpression of Ether À Go-Go K+ Channel:” Continue reading Corrections in PLoS One, Nature Medicine for Zhiguo Wang, and details about Montreal Heart Institute investigation

Why editors should stop ignoring anonymous whistleblowers: Our latest LabTimes column

A retraction notice appeared a few months ago in the Biophysical Journal:

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).

This article has been retracted at the request of Edward Egelman, Editor-in-Chief.

The editors have noted that there is a substantial overlap of figures and text between this Biophysical Journal article and D. Rutkauskas, V. Novoderezkhin, R.J. Cogdell and R. van Grondelle. Fluorescence spectral fluctuations of single LH2 complexes from Rhodopseudomonas acidophila strain 10050. Biochemistry, 43 (2004) 4431–4438, doi:10.1021/bi0497648. The submission of this paper was inconsistent with the Biophysical Journal policy which states: “Manuscripts submitted to Biophysical Journal (BJ) must be original; papers that have already been published or are concurrently submitted elsewhere for publication are not acceptable for submission. This includes manuscripts previously submitted to BJ, as well as material that has been submitted to other journals while BJ is considering the manuscript. If some part of the work has appeared or will appear elsewhere, the authors must give the specific details of such appearances in the cover letter accompanying the BJ submission. If previously published illustrative material, such as figures or tables, must be included, the authors are responsible for obtaining the appropriate permissions from the publisher(s) before the material may be published in BJ”. We are therefore retracting the publication of the Biophysical Journal article.

Ordinarily, such duplications go to the bottom of our list of retractions to cover, despite how common they are. There’s usually less of a story behind them than there is behind a completely opaque notice, or behind one that sports a whiff of fraud. But they’re still important, as Bruce Chabner, the editor of The Oncologist, pointed out in a recent issue of his journal in which a duplication retraction appeared: Continue reading Why editors should stop ignoring anonymous whistleblowers: Our latest LabTimes column

Lab squabble leads to retracted correction over authorship in British Journal of Haematology

Here’s a he said-he said that left one author with a publication, then nothing, and us scratching our heads.

In March 2010, the British Journal of Haematology issued a rather straightforward correction regarding a 2007 article by a group of researchers from Kansas Kansas City, Missouri.

The glitch? The manuscript evidently left out an author:

In Iyamu et al (2007), the list of authors was incorrectly published and should have read:

Efemwonkiekie W. Iyamu, Syed Jamal, Chiazotam Ekekezie and Gerald M. Woods

Or maybe not. The journal is now retracting the correction: Continue reading Lab squabble leads to retracted correction over authorship in British Journal of Haematology

New retraction sheds light on Medical College of Georgia vascular biology case

In late January, we wrote a post about a retraction in the journal Molecular Endocrinology involving work from the lab of Stephen M. Black, of the Vascular Biology Center at at the Medical College of Georgia.

At the time, we didn’t know much. The notice was pretty thin sauce, although it hinted at “significant concerns with the data,” and we were led to believe that the first author of the article, Neetu Sud, a post-doc in Black’s lab, might have been implicated in those concerns. Because Black’s lab was working with substantial amounts of NIH funding, the prospect of an investigation by the Office of Research Integrity seemed likely.

Now we have a little more to go on. The American Journal of Physiology: Lung Cellular and Molecular Physiology has retracted another article by Sud and Black. The paper, titled “Protein kinase Cδ regulates endothelial nitric oxide synthase expression via Akt activation and nitric oxide generation,” appeared in 2008 and included a third author, Stephen Wedgwood, of Northwestern University. It has been cited 10 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice: Continue reading New retraction sheds light on Medical College of Georgia vascular biology case

Two murky retractions in Chemosphere for authorship issues

The journal Chemosphere has retracted two papers over authorship concerns. The problem is, we don’t really know what those concerns are.

Here’s one notice: Continue reading Two murky retractions in Chemosphere for authorship issues

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:” Continue reading Second retraction arrives in Alirio Melendez case

A model retraction notice in Retrovirology

A retraction appeared earlier this month in Retrovirology that we think could be a model for other scientists and journals facing similar situations. The paper by Canadian and Chinese authors, “The cellular source for APOBEC3G’s incorporation into HIV-1,” was originally published in January 2011 and cited just once, according to Thomson Scientific’s Web of Knowledge. Here’s the notice: Continue reading A model retraction notice in Retrovirology
