Group retracts microRNA paper after realizing reagent was skewing results

A retraction from a high-profile group uncovered a technical limitation involving a widely used reagent.

Some quick background: the sequence hypothesis central hypothesis dogma of biology states that DNA gets transcribed to RNA that gets translated into proteins. Some RNAs, however, don’t code for proteins, but instead help to regulate gene expression. These microRNAs are tiny in size, but can regulate gene expression across animal and plant kingdoms.

In September 2011, the Molecular Cell published an entire issue with regulatory RNA as its theme. V. Narry Kim, associate professor at Seoul National University and high-profile microRNA researcher contributed a study that her group has now retracted just months later on June 29.

The problem? A reagent used to purify miRNAs favors some miRNAs and fails to isolate those rich low in guanine and cytosine — two of the four building blocks of RNA — or those with few secondary folding structures.

University of Michigan psychologist resigns following concerns by statistical sleuth Simonsohn: Nature

A second psychology researcher has resigned after statistical scrutiny of his papers by another psychologist revealed data that was too good to be true.

Ed Yong, writing in Nature, reports that Lawrence Sanna, most recently of the University of Michigan, left his post at the end of May. That was several months after Uri Simonsohn, a University of Pennsylvania psychology researcher, presented Sanna, his co-authors, and Sanna’s former institution, the University of North Carolina, Chapel Hill, with evidence of “odd statistical patterns.”

Simonsohn is the researcher who also forced an investigation into the work of Dirk Smeesters, who resigned last month. Last week, Yong reported that Simonsohn had uncovered another case that hadn’t been made official yet.

According to today’s story, Sanna has asked the editor of the Journal of Experimental Social Psychology — which is also retracting one of Smeesters’ papers — to retract three papers published from 2009 to 2011. These are the three he seems to have published there during that time: Continue reading University of Michigan psychologist resigns following concerns by statistical sleuth Simonsohn: Nature

Plagiarism leads to retraction of liver cancer paper

The journal Digestion has a retraction notice that’s, well, an amusing morsel.

At issue was a 2011 paper on a biomarker for liver cancer by a group of Turkish authors who plagiarized from the work of others.

Here’s the notice for the article, titled “Diagnostic and Prognostic Validity of Golgi Protein 73 in Hepatocellular Carcinoma“: Continue reading Plagiarism leads to retraction of liver cancer paper

Elsevier parasitology journal retracts paper after finding author made up peer reviewer email addresses

Note to authors: If a journal asks you to suggest reviewers for your submitted manuscript, don’t thank them by faking the reviewer’s emails.

You might just get caught.

That’s what happened recently at Experimental Parasitology, according to the retraction notice for “Entamoeba histolytica: Cloning, expression and evaluation of the efficacy of a recombinant amebiasis cysteine proteinase gene (ACP1) antigen in minipig:” Continue reading Elsevier parasitology journal retracts paper after finding author made up peer reviewer email addresses

When is it acceptable to use some of the same data in separate papers?

Duplication — sometimes referred to “self-plagiarism,” with a lack of precision — is a frequent cause of retractions. Usually, it’s of text that authors have used elsewhere. But what about data? In our new LabTimes column, we describe a hypothetical situation: Continue reading When is it acceptable to use some of the same data in separate papers?

Pulp fiction: doubtful “veracity” leads to retraction of endodontics paper

This one’s like taking candy from a baby.

The Journal of Endodontics — or JOE — has retracted a 2011 article (its online date) on the prospects of tissue engineering for the mouth by a group of Chinese authors who appear to have tried to pass bogus data into print.

The paper was titled “Mineralized Tissue Formation by Bone Morphogenetic Protein-7–transfected Pulp Stem Cells“. According to the notice: Continue reading Pulp fiction: doubtful “veracity” leads to retraction of endodontics paper

Another opaque notice from the JBC, for paper author says is correct and valid

The Journal of Biological Chemistry has posted another of its inscrutable and opaque retraction notices, this one for a study first published in September 2011. The retraction reads in full: Continue reading Another opaque notice from the JBC, for paper author says is correct and valid

Science has “not asked for a correction or retraction” of arsenic life paper, and why situation is unlike XMRV-CFS

The science world has been abuzz with news that a 2010 Science paper on an arsenic-based strain of bacteria had been refuted by two new studies published Sunday night. Yesterday on Retraction Watch, David Sanders argued the paper should still be retracted. So we were curious whether the editors of the journal had ever asked Felisa Wolfe-Simon and her colleagues to retract the paper. Science tells Retraction Watch: Continue reading Science has “not asked for a correction or retraction” of arsenic life paper, and why situation is unlike XMRV-CFS

Noteworthy: Journal posts all the corrections it wanted in a climate change paper after authors refuse most

In a case of refreshing transparency, a journal has published a detailed list of corrections it requested from authors of a paper on the costs of climate change, even though the authors declined to make most of them.

Earlier this year, the journal Ecological Economics published a paper that cast some doubt on the FUND model, which, as the article explains:

The FUND model of climate economics, developed by Richard Tol and David Anthoff, is widely used, both in research and in the development of policy proposals. It was one of three models used by the U.S. government’s Interagency Working Group on the Social Cost of Carbon in 2009 (Interagency Working Group on Social Cost of Carbon, 2010). The Working Group’s “central estimate” 1 of the social cost of carbon (SCC), i.e. the monetary value of the incremental damages from greenhouse gas emissions, was $21 per ton of CO2.

The paper concluded: Continue reading Noteworthy: Journal posts all the corrections it wanted in a climate change paper after authors refuse most

Despite refutation, Science arsenic life paper deserves retraction, scientist argues

David Sanders

Yesterday, Science published two papers which undercut an earlier paper in the journal claiming to show evidence for an arsenic-based strain of bacteria. Guest poster David Sanders, a structural biologist at Purdue University who was involved in a Retraction Watch story in May, argues that the journal could have avoided publishing the rebuttals—a swift retraction of the original was (and still is) the better move.

Allow me to apologize from the start. This narrative is not a typical Retraction Watch post, because it contains a number of personal elements. However, it would be hard to separate my perspective from my experience.

I will begin by asserting that, despite Rosie Redfield’s many valuable contributions to refuting the Wolfe-Simon paper that have culminated with the publication of data she and other investigators have obtained, there was no need for Science to publish additional articles. The Wolfe-Simon paper never should have been published. The only responsible action on the part of Science would be to retract the original article.
