A correction for Luk van Parijs and colleagues for a “clerical error”

Luk van Parijs, a former associate professor of biology at the Massachusetts Institute of Technology (MIT) who was fired in 2005 after confessing to data fabrication and sentenced last year to six months of house arrest, can add another correction to his list of several retractions and errata.

Here’s the notice for “Interferon γ is required for activation-induced death of T lymphocytes,” from the Journal of Experimental Medicine (JEM): Continue reading A correction for Luk van Parijs and colleagues for a “clerical error”

Pair of graphene papers retracted

Graphene has been hot for several years. Here’s what the Royal Swedish Academy of Sciences had to say about it in 2010 when awarding two researchers the Nobel Prize in Physics for their work:

Graphene is a form of carbon. As a material it is completely new – not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.

But one researcher may have allowed his enthusiasm for graphene to get ahead of him. He and his unwitting co-authors have now lost two papers thanks to that enthusiasm. Continue reading Pair of graphene papers retracted

Assay come, assay go: Corporate takeover leads to retraction of device analysis

A group of hematology researchers in Canada lost a publication to the merger of two medical device makers, after the acquiring company apparently decided not to pursue marketing the product in question.

An April 23 retraction notice in the International Journal of Laboratory Hematology about the article, “Enhanced flagging and improved clinical sensitivity on the new DxH 300TM Coulter® cellular analysis system,” originally published in February, tells the tale: Continue reading Assay come, assay go: Corporate takeover leads to retraction of device analysis

JACS temporarily pulls “space dinosaurs” paper for alleged duplication

Duplication has, as we noted on Twitter the other day, been tripping up more and more scientists. And now self-plagiarism has snared a prominent Columbia University chemist in a paper that left many people scratching their heads to begin with.

As reported by the Chembark blog and Nature, the Journal of the American Chemical Society (JACS) has pulled a paper by Ronald Breslow for alleged duplication. The page for “On Evidence for the Likely Origin of Homochirality in Amino Acids, Sugars, and Nucleosides on Prebiotic Earth,” originally published on March 25, now includes this: Continue reading JACS temporarily pulls “space dinosaurs” paper for alleged duplication

Journal retracts two Stapel papers, on salesmen and on women who change their names when they marry

The journal Basic and Applied Social Psychology has retracted two articles by Diederik Stapel, the Dutch researcher who has admitted falsifying his data. Stapel was suspended from his post at Tilburg University in September.

Here are the notices, which appear together: Continue reading Journal retracts two Stapel papers, on salesmen and on women who change their names when they marry

Authors’ public dispute over retraction notice in Cytokine ends in a draw, bruises journal

Cytokine had an interesting retraction notice this year that points up the pitfalls — perhaps necessary, perhaps not — that journals can step in when they give authors the benefit of the doubt.

Here’s the story: A doctoral student named Varun Kesherwani was working in the lab of Ajit Sodhi, a U.S.-trained and well-published cell biologist at Banaras Hindu University. Kesherwani’s Linkedin page lists him as a postdoc at the University of Nebraska.

The two were co-authors on a 2007 paper in Cytokine, “Quantitative role of p42/44 and p38 in the production and regulation of cytokines TNF-α, IL-1β and IL-12 by murine peritoneal macrophages in vitro by Concanavalin A.” (That paper has been cited nine times, according to Thomson Scientific’s Web of Knowledge, including by the retraction notice.)

But it seems Kesherwani, who was listed as the paper’s corresponding author despite his junior status, did not have his mentor’s blessing when he submitted the manuscript. Continue reading Authors’ public dispute over retraction notice in Cytokine ends in a draw, bruises journal

Patient database errors lead to three rheumatology retractions

The authors of three papers in Rheumatology International about systemic sclerosis, also known as scleroderma, are retracting them after patients were misidentified in databases. According to the three notices:

This article has been retracted at the request of the authors. The authors made a serious statistical error which unfortunately invalidates their results.

Corresponding author Metin Isik tells Retraction Watch that the error was adding a patient with systemic sclerosis database twice, and adding another patient with polymyositis, not systemic sclerosis, to the sclerosis database. (Why the journal didn’t spell that out in the notice is anyone’s guess, but we’ve asked the editor for comment and will update with anything we hear back.)

It’s easy to see how three patients would affect the results of “Systemic sclerosis and malignancies after cyclophosphamide therapy: a single center experience,” Continue reading Patient database errors lead to three rheumatology retractions

Surgery journal retracts cancer paper for duplication after “naive” response from authors

The Annals of the Royal College of Surgeons of England has an informative retraction notice about a recent paper it published that was marred by self-plagiarism. The article, “Current concepts of surveillance and its significance in head and neck cancer,” from a group of researchers at Grant Medical College, in Mumbai (which is known to this blog) and Royal Marsden Hospital in London, appeared last November. It soon was found to be awfully similar to a 2009 article by the same group of authors (sort of) in a different journal.

Here’s what the Annals had to say: Continue reading Surgery journal retracts cancer paper for duplication after “naive” response from authors

The HeLa problem: What a retraction says about whether cancer researchers can trust their cell lines

Retraction Watch readers who’ve read Rebecca Skloot’s bestseller The Immortal Life of Henrietta Lacks may remember that decades ago, scientists began realizing that Lacks’s cells, now known as the HeLa cell line and used in labs around the world, were so good at proliferating that they had taken over many other cell lines researchers use to study human disease.

Such readers would have been nodding their heads at a front-page Wall Street Journal on Saturday. As Amy Dockser Marcus (no relation to Adam) reports: Continue reading The HeLa problem: What a retraction says about whether cancer researchers can trust their cell lines

A retracted periodontitis-heart disease paper that didn’t make it into the new AHA review

On Wednesday, the American Heart Association announced something that those of us who’d been reading the medical literature carefully had known for a while: Bad gums do not cause heart disease.

Periodontitis is linked to bad heart disease, you see, as studies have shown, and periodontists have sure been using this as an excuse to tell us to floss. But there’s never been a convincing study showing that one causes the other.

In fact, it’s not even clear how you’d do that study. “Let’s see, for a control group, we should have 100 people convince themselves they’re flossing for a year, but not actually floss….oh, what else can we get funding for?”

That “news” prompted an email from Retraction Watch friend Marc Abrahams, Continue reading A retracted periodontitis-heart disease paper that didn’t make it into the new AHA review
