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

with one comment

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: Read the rest of this entry »

Duplication in physics journal questions key tenet of quantum mechanics

with 2 comments

cmpHere’s a physics question: How is it possible to be in two places at the same time?

Answer: Submit the same manuscript twice and hope the editors forget to feed Schrodinger’s cat.

The journal Condensed Matter Physics is retracting a 2013 paper by a Ukrainian scientist who’d published essentially the same paper seven years earlier.The article was titled “On the origin of power-law distributions in systems with constrained phase space,” and was written by an E.V. Vakarin, of the Institute for Condensed Matter Physics, in Lviv UMR 7575 LECA ENSCP-UPMC-CNRS.

Doing the right thing: Authors retract lubricant paper whose findings they can’t reproduce

leave a comment »

wearcoverThe journal Wear — an Elsevier title, not a Condé Nast fashion magazine — has retracted a paper by a pair of Chinese physicists after the researchers were unable to replicate their findings.

The 2009 article, “Microstructure and tribological characterizations of Ni based self-lubricating coating,” was written by authors from the MOE Key Laboratory for Nonequilibrium Synthesis and Modulation of Condensed Matter and the MOE Key Laboratory for Strength and Vibration at Jiaotong University, in Xi’an. It purported to find that: Read the rest of this entry »

Seeing triple: Optics paper proves to be one of three, retracted

with 12 comments

joptA team of physicists has lost their 2013 paper in the Journal of Optics after the publisher learned that the article had already appeared in print twice before.

The article, “Inscription of narrow bandwidth Bragg gratings in polymer optical fibers,” came from researchers at the Instituto de Telecomunicacoes, in Portugal, and the Aston Institute of Photonic Technologies, in Birmingham, England. Per the abstract: Read the rest of this entry »

“Complete copies” earn physicists in Malaysia a pair of retractions

with 4 comments

pramanaThe physics journal Pramana — a publication of the Indian Academy of Sciences — has retracted two studies by a group of researchers in Malaysia who appear to have cobbled together their papers from other sources.

The 2007 articles came from A.R.M. Yusoff, M.N. Syahrul and K. Henkel, of the University Science Malaysia, in Penang. One was titled “High resolution transmission electron microscope studies of a-Si:H solar cells,” and the other, “Hydrogenated nanocrystalline silicon germanium thin films.” The retraction notices are identical, and read: Read the rest of this entry »

“Stupid, it should not be done that way”: Researcher explains how duplications led to a retraction

with 25 comments

Rienk van Grondelle, via VU

More than two years ago, we wrote about a retraction for duplication in Biophysical Journal prompted by an email from pseudonymous whistleblower Clare Francis. That post generated a robust discussion, including one comment from someone calling himself or herself “Double Dutch.”

This past weekend, the last author of that paper, Rienk van Grondelle, left a lengthy response to that comment in which he explained how the duplication happened. We’ve confirmed that it was van Grondelle who left the comment, which we reproduce here in full (we’ve added paragraph breaks for readability): Read the rest of this entry »

Holes in ASS as journal pulls two papers

with 6 comments

asscoverThe journal Applied Surface Science (okay, so maybe it’s not called ASS at the home office) is retracting a pair of articles in its December issue.

The first, “Structure and mechanical properties of Ni–P electrodeposited coatings,” appeared in 2009 and was written by a group of researchers in Beijing. It has been cited nine times, according to Thomson Scientific’s Web of Knowledge. Its problem: Plagiarism. According to the retraction noticeRead the rest of this entry »

Plagiarism leads to retraction of conduction paper

with 8 comments

physica bPhysica B: Condensed Matter has retracted a 2013 paper by a group from Morocco and France for, well, inappropriate condensation of printed matter.

The article, “Granular and intergranular conduction in La1.32Sr1.68Mn2O7 layered manganite system,” came mostly from a team of physicists at  University Ibn Zohr, and appeared in June.

That’ll do it: Physics paper retracted for a “pattern that is unphysical”

with 8 comments

j phys dLast December, we brought you the story of a math paper that was retracted because it made “no sense mathematically.” Today, we have that retraction’s cousin: A physics paper retracted because some of the data are “unphysical.”

Here’s the notice for “Room temperature ferromagnetism in pure and Co- and Fe-doped CeO2 dilute magnetic oxide: effect of oxygen vacancies and cation valence,” which was published in April 2011 in the Journal of Physics D: Applied Physics: Read the rest of this entry »

Author of “way out there” paper merging physics and biology has second paper retracted

with one comment

jcellsigIn February, we brought you the story of Konstantin Meyl, a

professor who claims to have developed “a self-consistent field theory which is used to derive at all known interactions of the potential vortex”

At the time, one of Meyl’s papers — which a reviewer had called “way out there” — had just been retracted, for duplication. Now a second paper — among the works from which the first retracted paper had drawn — has been retracted.

Here’s the notice from the Journal of Cell Communication and Signaling (which is buried in a footnote at the bottom of the paper): Read the rest of this entry »
