Controversial researcher loses 12th paper that’s “literally copied;” authors object

A physics journal has retracted a 2011 paper by a group of scientists based in Italy, noting it’s “literally copied” from a paper by the same authors.

This is the 12th retraction for the paper’s first author Alberto Carpinteri, who is known in the engineering community for championing some controversial ideas, such as that the Shroud of Turin is as old as Jesus (contradicting carbon dating). In 2015, a journal he used to edit — Meccanica — retracted 11 of his papers, noting that “the editorial process had been compromised.”

In the latest notice, the Journal of Statistical Mechanics: Theory and Experiment (JSTAT) says its investigation found a substantial portion of the paper—including the main analysis and conclusion—had been lifted from a paper published in another journal several months before.

Last author of the latest paper to be retracted, Amedeo Manuello Bertetto from Polytechnic University of Turin, told us the authors strongly opposed the journal’s decision:  Continue reading Controversial researcher loses 12th paper that’s “literally copied;” authors object

Publisher responds to public health journal editorial board’s “grave concerns”

A representative of Taylor & Francis has responded to concerns raised by former and current editorial board members of an occupational health journal, after the publisher took some significant actions without consulting the board.

The board’s main concerns: That the publisher hired a new editor with industry ties, and withdrew a paper by the former editor that was critical of corporate-sponsored research.

In a letter to the editorial board of the International Journal of Occupational and Environmental Health dated last week, managing director Ian Bannerman writes:

Top physicist loses another paper; tally now up to 7

A physics journal has retracted a paper from a leading physicist in India over duplication.

The paper’s first and corresponding Naba K. Sahoo has had six papers retracted for the same reason — four earlier this year and two last year.

The new retraction brings Sahoo’s total to seven, by our count.

The duplication allegations began several years ago, after Sahoo’s colleagues at Bhabha Atomic Research Centre (BARC), part of Indian government’s Department of Atomic Energy, accused him of plagiarizing his own work.

Thomas Lippert, editor-in chief of Applied Physics A: Material Science & Processing, told us: Continue reading Top physicist loses another paper; tally now up to 7

“Dramatic impact:” Authors misread breast cancer treatment database, retract paper

A journal has retracted a 2016 study on the use of radiation by breast cancer patients after the authors misinterpreted what was reported in a national cancer database.

Correcting for the error, according to the retraction notice, had a “dramatic impact on the original article data and conclusions.”

Quyen Chu, a surgeon at Louisiana State University Health Shreveport, told us that the problem appears to stem from a misunderstanding about the US National Cancer Database (NCDB). After the paper was published, the NCDB pointed out to Chu that a key data point had not been reliably or consistently collected during the timeframe relevant to the study. The database’s user’s manual says essentially the same thing; Chu said he and his authors read it, but misunderstood it.

The original Journal of the American College of Surgeons study looked at whether a 2004 National Comprehensive Cancer Network treatment guideline — which suggested some patients could avoid radiation on top of surgery and hormone therapy — led to an actual decrease in radiation therapy. But the error forced the authors to drop tens of thousands of patients treated before 2004, which had a severe impact on their ability to draw conclusions.

Chu told us:

Paper by Harvard cancer biologist flagged over “credible concerns”

A cancer biologist at Harvard who’s issued multiple editorial notices in recent years has received an expression of concern about a 2011 paper, citing “credible concerns” with the data and conclusions.

The publisher does not detail the nature of the issues in the notice.

In the past few years, last author Sam W. Lee lost a Molecular Cell paper in 2013 due to figure duplication and a Journal of Biological Chemistry paper in 2015, citing “manipulated” data in a figure.

Lee also issued two mega-corrections in 2011 in Nature and Current Biology, which also cited figure duplication. Interestingly, both papers were corrected for a second time — the 2006 Current Biology paper in 2016, over figure-related errors, and the 2011 Nature paper in 2015, over concerns the animals used may have experienced excess suffering (prompting an editorial from the journal).

The latest notice, issued by the Journal of Biological Chemistry, doesn’t provide much information for the basis of its expression of concern over Lee’s 2011 paper: Continue reading Paper by Harvard cancer biologist flagged over “credible concerns”

Despite author’s protest, journal removes paper on emergency department prices

A journal has temporarily removed a paper showing the dramatic differences in the cost of providing emergency care that caught national attention (and some criticism from emergency care providers), despite the first author’s claims that the results are valid.

The paper, published online in February by the Annals of Emergency Medicine, showed that it can cost significantly more for patients to be treated at emergency departments than at urgent care centers, even for the same conditions. Soon after the paper was published, first author Vivian Ho at Rice University was told by the American College of Emergency Physicians, which publishes the journal, that there were some errors in the appendix, and they wanted to reanalyze the entire paper.

Ho told us:

Former UCLA vice-chancellor loses cancer paper for image manipulation

The former vice chancellor for research at the University of California, Los Angeles, has retracted a 2012 paper after an internal investigation found evidence of image manipulation.

The journal Molecular Cancer Therapeutics received a letter about the problems with the paper from the UCLA Research Integrity Officer, and a retraction request from last author James Economou, also the chief of surgical oncology.

According to the notice, the paper duplicated images from a 2011 paper also by first author Ali Jazirehi, based at UCLA. This is Jazirehi’s second retraction.

Here’s more from the notice:

Can we do math unconsciously? Replicators of a prominent 2012 study have some doubts

In 2012, news media were abuzz with a new finding from PNAS: Authors based in Israel had found evidence that our brains can unconsciously process more than we thought — including basic math and reading.  In other words, the authors claimed people could read and do math without even knowing what they were doing.

With such a major development in the field of consciousness research, other groups quickly got to work trying to replicate the findings. Those efforts have taken some twists and turns — including a recent retraction of a replication paper that was, itself, not reproducible (which is not something we see every day). But overall, five years after the initial, remarkable result, the replication efforts are calling it into question.

According to Pieter Moors at KU Leuven, a researcher in this field:

After researcher is convicted of sexual assault, journal retracts her co-author’s paper

A disability journal has retracted a paper supposedly penned by a man with severe disabilities, citing duplication.

Although the reason for the retraction may sound run-of-the-mill, this situation is far from ordinary.

The author, known as DMan Johnson — or simply “D.J.” — has cerebral palsy, and was communicating using a controversial technique called “facilitated communication” with Anna Stubblefield, the former chairwoman of philosophy at Rutgers University. In October 2015, Stubblefield was convicted of sexually assaulting D.J., who has been diagnosed with spastic quadriplegia and severe mental retardation. The following month, she was sentenced to 12 years in prison.

In October 2015, Disability Studies Quarterly issued a statement that it was taking a second look at papers by Stubblefield, but did not specify which ones.

Updated: Science fish-microplastics paper retracted

Despite continuing to vigorously defend their work, the authors of a controversial paper about the effects of human pollution asked Science to retract the paper last week.

According to a release from Uppsala University issued today, authors Peter Eklöv and Oona Lönnstedt submitted their request to Science last week, noting they wanted to withdraw the paper “as long as a suspicion of misconduct remains.”

The release — which echoes a statement that was also provided to Nature — notes:
