Two more retractions appear for prominent MIT cancer researcher Robert Weinberg

genes and developmentTwo identical retraction notices have popped up for MIT professor Robert Weinberg, a highly-cited cancer researcher who had a retraction and a correction in 2013, both in Cancer Cell. 

These two new retractions, in Genes and Development, stem directly from another paper by Weinberg and colleagues in Cell that will apparently be retracted, as the “same analytical methodology was used,” according to the notices [see bottom of the post for an update].

Weinberg is highly regarded, and at least 20 of his papers have been cited over a thousand times.

First author Scott Valastyan was a promising postdoc at the time of the paper’s publication. He was a 2011 Runyon Fellow at Harvard, a three-year, $156,000 award for outstanding cancer postdocs. He doesn’t seem to have published anything since 2012, though he is listed as a joint inventor with Weinberg on patents filed in 2009 and 2014.

Here are the notices for “Concomitant suppression of three target genes can explain the impact of a microRNA on metastasis” (cited 73 times, according to Thomson Scientific’s Web of Knowledge) and “Activation of miR-31 function in already-established metastases elicits metastatic regression” (cited 54 times), both paywalled: Continue reading Two more retractions appear for prominent MIT cancer researcher Robert Weinberg

Troubled article ranking business schools earns expression of concern

jpimAn article that ranked University of Missouri-Kansas City number one in an area of business school training is set to receive an expression of concern. The move follows months of questions over the ranking’s legitimacy, following revelations such as a relationship between the authors and both the school and its top ranked researcher in the field.

In 2011, the business world got a bit of a surprise: In the field of innovation management, the study of how entrepreneurs convert good ideas into profit, the number one school – according to an article in the Journal of Product Innovation Management — was UMKC. Not Harvard, not Stanford, not any other institution that normally tops these types of rankings. UMKC’s Henry W. Bloch School of Management was also home to the number one researcher in that field, Michael Song.

The school, of course, was elated, immediately issuing a press release titled “UMKC Ranked No. 1 in the World.”

But after publication, a UMKC professor raised concerns about the paper’s methodology. An investigation by the Kansas City Star uncovered some issues:

Sticky situation: Paper using honey for healing pulled over data issues

A paper on dressing wounds with honey has been retracted after the journal realized that an outlier patient was throwing off the data analysis.

Honey has been used for millennia as an antimicrobial wound dressing. Doctors can even buy sterile preparations of the sweetener. But the evidence that honey is better than other wound dressings is still inconclusive.

According to the retracted paper, published in International Wound Journal in 2008, Manuka honey has an acidic pH which helps reduce the alkaline environment of chronic woulds. Indeed, the authors found that Manuka honey dressings lowered wound pH and reduced wound size.

Sadly, the paper was pulled in 2014, after someone realized one patient had a particularly large wound that was throwing off statistics. The injury was 61 cm^2 at the beginning of the study, while the others ranged from .9 to 22 cm^2. After removing that patient from the analysis, the results no longer held up.

Castle made of sand: Self-plagiarism washes away paper on dune particles

sedgeolA group of geologists in China have lost their paper on the aerodynamics of sand particles because the article was mashed together from previous publications.

The article, “The influence of sand diameter and wind velocity on sand particle lift-off and incident angles in the windblown sand flux,” appeared in the May 2013 issue of Sedimentary Geology. It was written by a team from the Key Laboratory of Mechanics on Western Disaster and Environment at Lanzhou University.

Here’s the notice: Continue reading Castle made of sand: Self-plagiarism washes away paper on dune particles

Cell biologists in South Korea retract two papers

jbcA group of researchers at two universities in South Korea have retracted two cell biology papers featuring retinoic acid.

The most recent retraction appears in the Journal of Biological Chemistry. Although, in typical JBC fashion, the reason for it is anyone’s guess.

Here’s the unhelpful notice for “ASXL1 represses retinoic acid receptor-mediated transcription through associating with HP1 and LSD1:” Continue reading Cell biologists in South Korea retract two papers

Warning: plagiarism may be hazardous to your safety paper

12 Process Safety and Environmental Protection (once)A paper on making emergency evacuations more efficient at facilities that handle hazardous materials has been retracted for plagiarism.

According to the Process Safety and Environmental Protection retraction notice, the 2013 paper, by a group at Tsinghua University in Beijing, plagiarized part of a 2007 article by Greek researchers called “Modeling emergency evacuation for major hazard industrial sites.” (The 2007 article has been cited 46 times, according to Google Scholar.)

Here’s the notice for “Emergency Response Plans Optimization for Unexpected Environmental Pollution Incidents using an Open Space Emergency Evacuation Model” (paywalled): Continue reading Warning: plagiarism may be hazardous to your safety paper

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.
