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 pap er 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:

Meet our new staff writer, Andrew P. Han

Please welcome Andrew P. Han, the newest addition to the Retraction Watch team.

Andy comes to Retraction Watch and the Center for Scientific Integrity from GenomeWeb, where he covered the explosion of CRISPR/Cas9 into the research and biotech scene over the last several years. He has also freelanced for Wired.com, Popular Mechanics.com, Newsweek, and Food & Wine.

Andy’s beat at Retraction Watch will of course be retractions, but he’ll also be helping us broaden our coverage of the intersection between scientific misconduct at the law — so if you have court documents or stories, send them along.

When most faculty publish in predatory journals, does the school become “complicit?”

Predatory journals – which charge high fees and often offer little-to-no vetting of research quality – are a problem, and lately an easy target for authors eager to spoof the problems of the publishing system. Although many researchers try to steer clear, not all do – a recent paper showed that some top economists publish papers in potentially predatory journals. Now, a new paper in the Journal of Scholarly Publishing reports the problem may be even more widespread. Derek Pyne found that most of his colleagues at the School of Business and Economics at Thompson Rivers University in British Columbia, Canada have at least one paper in a predatory journal. We talked to Pyne about how his colleagues and administrators reacted to his findings – and how he believes they should address them.

Retraction Watch: Why did you decide to look at how many of your colleagues in the business school have published in predatory journals?

Updated: Vaccine-autism study retracted — again

For the second time, a journal has quickly retracted a study that suggested vaccines raise the risk of autism and other neurodevelopmental disorders.

The study first raised a furor last year, prompting a Frontiers journal to quickly retract it. After it was republished in the Journal of Translational Science this month, that journal has also retracted it.

Although the titles of the two papers changed, the abstracts were nearly identical. Both studies surveyed the parents of 666 home-schooled children, 39% of whom where not vaccinated, and concluded that vaccination increased the risk of neurodevelopmental problems, particularly if children were born prematurely.

A representative of the Journal of Translational Science told us “Pilot comparative study on the health of vaccinated and unvaccinated 6- to 12-year-old U.S. children” has been retracted, and it will update us with an explanation.

Here’s more from the (now-retracted) abstract:

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:
