“Major errors” lead to retraction of Nature Photonics paper on quantum dots

Maybe it’s an occupational hazard of dealing with quantum physics — uncertainty and all that — but a group of Swiss researchers has retracted their paper on quantum dots after discovering “major errors” that undermined their conclusions.

The article, published in 2010 as a research letter in Nature Photonics, was titled “Polarization-entangled photons produced with high-symmetry site-controlled quantum dots,” by Eli Kapon and colleagues.

According to the retraction notice: Continue reading “Major errors” lead to retraction of Nature Photonics paper on quantum dots

High school whiz kid retracts PLoS ONE herd immunity paper

Georgette speaking at the Davidson Institute’s award ceremony, Library of Congress, 2008

It’s pretty impressive to publish two peer-reviewed papers on complicated vaccination models while you’re still in high school. So it’s not surprising that Nathan Georgette, who grew up outside of Jacksonville, Florida, earned a prestigious fellowship from the Davidson Institute for Talent Development.

But perhaps even more impressive is realizing you’ve made a fundamental error in one of those studies, and retracting it while you’re still a college senior at Harvard. Continue reading High school whiz kid retracts PLoS ONE herd immunity paper

Updates: Journal of Climate adds info about withdrawn hot temps paper, chemistry journal corrects retraction notice

We have a few updates on stories we’ve covered.

In June, we wrote about the withdrawal of a paper claiming that temperatures in the last 60 years were warmest in the last 1,000 years. At the time, we reported, following posts by others, that the authors had been made aware of errors in their work and were withdrawing it to correct their calculations.

For several months, the page housing the Journal of Climate study read:

The requested article is not currently available on this site.

It still does. But another page that should house the paper now reads, as commenter Skiphil notes: Continue reading Updates: Journal of Climate adds info about withdrawn hot temps paper, chemistry journal corrects retraction notice

Radioactive fish study retracted for “significant and extensive” corrections

The authors of a study estimating how much radioactive material from two sunken Russian submarines is taken up by fish in the Barents Sea have retracted it, citing the need for “significant and extensive” corrections.

Here’s the notice, from Environmental Pollution: Continue reading Radioactive fish study retracted for “significant and extensive” corrections

Did a McLuhan moment lead to retraction in Chemistry — A European Journal?

The authors of a chemistry paper are retracting it after a Columbia University chemistry researcher pointed out a fatal misinterpretation of his own work in it.

Here’s the notice in Chemistry — A European Journal: Continue reading Did a McLuhan moment lead to retraction in Chemistry — A European Journal?

Authors retract Digestion paper for “unacceptably high number of errors”

A group of South Korean researchers has decided to withdraw a paper they recently published in the journal Digestion because it was filled with mistakes.

The paper, “Endoscopy-Based Decision Is Sufficient for Predicting Completeness in Lateral Resection Margin in Colon Endoscopic Submucosal Dissection,” was published earlier this year (and online in late 2011) by a group in Seoul. But according to the retraction notice:

Retraction six arrives for Ulrich Lichtenthaler

Ulrich Lichtenthaler

Ulrich Lichtenthaler, who has already retracted five papers for statistical irregularities, has retracted a sixth, “The Impact of Accumulating and Reactivating Technological Experience on R&D Alliance Performance,” in the Journal of Management Studies. The notice, which was first reported by the Open Innovation Blog, reads: Continue reading Retraction six arrives for Ulrich Lichtenthaler

Closing loop, Science retracts Hill group oxo paper

Craig Hill

Last month, we broke the news that Emory chemist Craig Hill and colleagues were retracting two papers in the Journal of the American Chemical Society and one in Science. At the time, the Science move was pending, but now the journal has officially pulled the article, titled “A Late-Transition Metal Oxo Complex: K7Na9[O=PtIV(H2O)L2], L = [PW9O34]9–”.

The notice reads: Continue reading Closing loop, Science retracts Hill group oxo paper

Three papers by German management prof retracted for duplication, statistical issues

Ulrich Lichtenthaler, a management professor in Germany, has had three papers retracted by two different journals, after readers noticed statistical irregularities.

Lichtenthaler was at the WHU – Otto Beisheim School of Management when he published the papers in 2009 and 2010. He is now at the University of Mannheim. The retraction in Strategic Organization was first reported by the Strategy Profs blog. It reads: Continue reading Three papers by German management prof retracted for duplication, statistical issues

JPET corrects Janssen antidepressant paper after neuroscience blogger notes errors

Are drug company R&D departments reading blogs?

In a recent paper, “Translational evaluation of JNJ-18038683, a 5-HT7 receptor antagonist, on REM sleep and in major depressive disorder,” researchers with New Jersey-based Janssen Pharmaceuticals Inc. tested whether a potential drug code-named JNJ-18038683 that binds to a receptor linked to depression could actually help patients.

Turns out, the drug was a flop, but Continue reading JPET corrects Janssen antidepressant paper after neuroscience blogger notes errors
