A first retraction for Einstein (no, not that one)

einsteinIn 1932, Einstein famously retracted his “cosmological constant.” Now, more than 80 years later, a Brazilian healthcare journal bearing his name has retracted its first paper.

The authors of the review, about the effects of neuromuscular electrical stimulation in hospitalized patients on ventilators, appear to made the genius move of trying to publish their paper in two different journals at once.

Here’s the top of an editorial announcing the retraction: Continue reading A first retraction for Einstein (no, not that one)

“Irreconcilable difference of opinion” divides math preprint

arxivA fight over a paper posted on preprint server arXiv.org has divided two mathematicians.

The authors initially posted the paper, which looks at the mathematical properties of spheres, in 2013. And that’s when the trouble started.

Apparently, after submitting the paper to a journal and receiving reviewer feedback, co-authors Fabio Tal at the University of São Paulo and Ferry Kwakkel, who got a PhD at the University of Warwick, began to fight over the content of the paper, causing Kwakkel to post his own version, and Tal to withdraw the previous one. “I believe we are severely at odds now,” Tal told Retraction Watch.

In February 2015, Kwakkel, posted a second paper on arXiv.org that he said is his “version” of the 2013 paper, with which it has “substantial text overlap.” Tal requested that the first paper be withdrawn; the note that now appears on “Homogeneous transformation groups of the sphere” cites an “irreconcilable difference of opinion”:

So-kalled research: French sociology journal retracts hoax article

societeThe world, it seems, cannot get enough of Sokal-type hoaxes.

A French journal, Sociétés, has retracted an article allegedly penned by one Jean-Marc Tremblay but actually written by two sociologists, Manuel Quinon and Arnaud Saint-Martin, who spoofed the work of the journal’s editor, Michel Maffesoli.

As the Crooked Timber blog explains, the article, “Automobilités postmodernes: quand l’Autolib’ fait sensation à Paris,” published in the Continue reading So-kalled research: French sociology journal retracts hoax article

Second cell bio retraction from UPitt investigation of tweaked images

Journal of Cellular Physiology: Volume 229, Number 10, October 2Two researchers, Tong Wu and Chang Han, have lost a second paper as the result of a University of Pittsburgh investigation into image manipulations.

The first retraction, in Journal of Cellular Biochemistry, went live in February. The researchers, currently based at Tulane University, were originally tapped by pseudonymous tipster Juuichi Jigen, who created a website in 2012 to chronicle the allegations.

The blog lists six papers by the pair with supposedly questionable figures. According to Jigen, this latest retraction, in the Journal of Cellular Physiology, contains a figure (2A) that appears to reuse data from another paper, and another figure (3) where the data appear to be manipulated.

Bielawski and Wiggins up retraction count to five with three in JACS

Journal of the American Chemical SocietyThe Journal of the American Chemical Society (JACS) has retracted three articles that had earned expressions of concern by chemistry researchers who were under investigation at the University of Texas, Austin.

Kelly Wiggins and Christopher Bielawski have already received two other retractions and several EoCs.

The newly retracted articles have each been cited more than 50 times, according to Thomson Scientific’s Web of Knowledge.

The three papers are: Continue reading Bielawski and Wiggins up retraction count to five with three in JACS

Opaque retraction notice for imaging paper

cmmmSometimes we run across retraction notices that are vague, and others that are contorted, but we’ve just found one that gets highest marks for being completely inscrutable.

The article, “Bayes Clustering and Structural Support Vector Machines for Segmentation of Carotid Artery Plaques in Multicontrast MRI,” was written by a group from China and Cambridge University in England — so, we’re thinking language ought not to have been much of a barrier to clear English. It appeared in November 2012 in Computational and Mathematical Methods in Medicine, and describes a way to analyze carotid artery plaque levels in MRI images.

But according to the notice, the technique did not work as planned (or so we think):

Biofuels paper burned by “improper citation methods” – ie, plagiarism

crestCritical Reviews in Environmental Science and Technology (CREST) has retracted a paper on biofuels for “improper citation methods.”

Given the journal’s track record, we’re guessing this is just another euphemism for plagiarism. (Also because the retraction notice flags a “breach of warranties made by the authors with respect to originality.”) In 2013, CREST retracted two papers for failing to use “proper citation,” which earned it top billing in our Lab Times column about publishers’ seemingly allergic reactions to the P-word.

Here’s some of the notice for “Promising Unconventional Pretreatments for Lignocellulosic Biomass”, which described new ways to process plant biomaterials into fuel: Continue reading Biofuels paper burned by “improper citation methods” – ie, plagiarism

Misconduct dissolves paper on possible clot-busters

amclct_v006i002.inddDrug researchers in India have lost their 2013 paper in ACS Medicinal Chemistry Letters because the first author fabricated findings.

The article, by a group from the Maharaja Sayajirao University of Baroda, Vadodara, in Gujarat, was attempting to synthesize and screen novel clot-busting drugs; one compound exhibited the same activity as aspirin or warfarin, but without increasing bleeding time.

Sadly, it appears as if this potential medical advance was not to be. Here’s the retraction notice for “Novel 2-Aminobenzamides as Potential Orally Active Antithrombotic Agents”: Continue reading Misconduct dissolves paper on possible clot-busters

Chinese heavy metal contamination paper purged for data theft

Environmental_Monitoring_and_AssessmentAn environmental journal has retracted a paper about pollution in China after it discovered the authors lifted the dataset from another group.

The authors of the study — which chronicled the degree of heavy metal pollution on the banks of the Pearl River Delta — didn’t have permission to use the data. Environmental Monitoring and Assessment‘s notice doesn’t suggest the data are inaccurate.

The heavy metals in the soil come from the many manufacturing plants in the area, including those that provide the West with blue jeans, phones, and other electronics. The pollutants’ effects are wide-reaching: According to the South China Morning Post, industrial outfits discharge huge volumes of toxic chemicals into the Pearl River, including arsenic, copper, cadmium, and mercury.

Researcher loses second bid to quash Diabetes expressions of concern

It hasn’t been a good week for scientists going to court to silence criticism of their work.

Yesterday, PubPeer won a near-complete victory in a case seeking the identities of their commenters. And also yesterday, a Massachusetts judge struck down — for the second time — a request by Mario Saad to remove expressions of concern about four of his papers in Diabetes.

In his ruling, Judge Timothy Hillman wrote: Continue reading Researcher loses second bid to quash Diabetes expressions of concern
