Plant biologist’s paper pulled for falsification, three more questioned on PubPeer

PMBP Cover ImagePhysiology and Molecular Biology of Plants has retracted a paper about using Darjeeling tea clones against abiotic stress for problems with one of the figures.

The specific problem: “falsification/fabrication” of data underlying the figure, which the corresponding author — Sauren Das from the Indian Statistical Institute in Calcutta, West Bengal — couldn’t resolve. Das told us he denies the allegations made by the journal.

Meanwhile, three other papers by Das have been questioned on PubPeer. 

Let’s take a look at the retraction note: Continue reading Plant biologist’s paper pulled for falsification, three more questioned on PubPeer

Confusion reigns: Are these four retractions for compromised peer review, or not?

Open Automation Journal CoverThe Open Automation and Control Systems Journal has published five items this calendar year — and all of those are retraction notices.

That’s what we’re sure about. Now to what we’re not clear on in this story, which is one of a growing number of cases we’ve seen in which so-called “predatory” publishers are starting to retract papers, perhaps because they hope the practice suggests they are rigorous. Four of the papers have been pulled for “compromised” peer review, some of which are due to the actions of an “external agent,” according to the journal. A co-author of one of these manuscripts, however, claims the paper has been pulled for using material from another researcher’s paper without acknowledgement but the journal has retracted it for issues with peer review.

The remaining paper has been pulled for plagiarizing from another published paper.

Let’s take a look at the retraction notice for the four papers felled by rigged peer review, which are all similar. They read: Continue reading Confusion reigns: Are these four retractions for compromised peer review, or not?

Neuroscience journal retracts expression of concern 15 years after investigation

Here’s something we don’t get to write about often: A journal has retracted an expression of concern (EOC) more than 15 years after issuing it.

What took so long? Apparently, the European Journal of Neuroscience (EJN) just recently learned about a review carried out by the author’s previous institution, which concluded that she had not committed misconduct.

Let’s take a look at the retraction note of the expression of concern, which was published last month: Continue reading Neuroscience journal retracts expression of concern 15 years after investigation

Paper linking fecal transplants to obesity in rats retracted for faked data

Diabetes Cover

A paper linking the fecal microbiome to obesity has been retracted after it became clear that one of the co-authors faked some of the data.

The 2014 paper in Diabetes — which found that rats given fecal transplants from obese mice were more likely to become obese themselves if given a particular diet — was pulled after after an institutional investigation found a co-author guilty of falsifying data underlying one figure and fabricating the data of two others.

Co-author Yassine Sakar — formerly based at the French National Institute of Agronomic Research (INRA) in Paris, France — was found responsible for the misconduct. But an official from the institution said that some responsibility must also be shared by the corresponding author Mihai Covosa, who has since resigned from the institution.

Here’s the retraction notice: Continue reading Paper linking fecal transplants to obesity in rats retracted for faked data

Biologist critiques own paper, journal retracts it — against her wishes

Evolution Cover ImageThe journal Evolution has retracted a 2007 paper about the roles of the different sexes in searching for mates, after the same author critiqued the work in a later paper. 

The case raises important questions about when retractions are appropriate, and whether they can have a chilling effect on scientific discourse. Although Hanna Kokko of the University of Zurich, Switzerland — who co-authored both papers — agreed that the academic literature needed to be corrected, she didn’t want to retract the earlier paper; the journal imposed that course of action, said Kokko.

Does posting on PubPeer count as prior publication? Journal says yes, rejects letter rebutting campus sexual assault data

Jim Hopper

Journals typically shy away from publishing data and text readers have seen before — but amidst the newly established norms of open science and data sharing, what counts as a prior publication?

We’re asking ourselves that question after learning that JAMA Pediatrics has rejected a letter rebutting a recent study in the journal about sexual assault on college campuses after deciding that posting the letter on PubPeer is a prior publication.

The submitted letter (which you can read here) was co-authored by independent consultant, therapist and researcher Jim Hopper, who is also a Teaching Associate in Psychology at Harvard Medical School. It concerned a 2015 paper published in JAMA Pediatrics, which suggested that the long-held belief that most rapists on college campuses are repeat offenders may be false. The findings can have major implications for university efforts to stop assaults, as institutions weigh whether to divert resources towards punishment (if serial offenders are largely responsible) or prevention (if most men only commit assaults once). Continue reading Does posting on PubPeer count as prior publication? Journal says yes, rejects letter rebutting campus sexual assault data

Authors correct highly cited biology paper due to “genuine mistake”

Journal of Cell ScienceAuthors of a highly cited biology paper in the Journal of Cell Science (JCS) have corrected the data underlying one of the figures.

The 2003 paper, “The transcription factor Slug represses E-cadherin expression and induces epithelial to mesenchymal transitions: a comparison with Snail and E47 repressors,” has been cited 566 times, according to Thomson Reuters Web of Science. One of the authors is the last author on a recent high profile retraction from Nature Genetics, which cost the first author a grant from the European Molecular Biology Organisation.

Engineer: Paper plagiarized my thesis — badly

GeoScience EngineeringAn engineering journal has published a statement by a researcher alleging that a 2015 paper in the same journal plagiarized his thesis — and was so poorly done it “should not have been published.”

In the “counterstatement” to the 2015 paper, Christian Seip of the Rostock University in Germany said the paper — about the development of a Marine Spatial Data Infrastructure (MSDI) in Croatia — took content from his dissertation thesis, about MSDI geoportals in Germany.

In addition, Seip argued that the original paper, “A Framework for Evaluation of Marine Spatial Data Geoportals Using Case Studies,” in GeoScience Engineering (GSE) — shows “major weaknesses” and therefore “should have not been published even [if] it was not plagiarized.”

Seip told us: Continue reading Engineer: Paper plagiarized my thesis — badly

NEJM quickly corrects disclosure statement, errors in diabetes paper

NEJM LogoAfter publishing a paper about neuropathy in diabetic patients last week, The New England Journal of Medicine (NEJM) immediately corrected it after editors learned of errors and some missing disclosures within the article.

The notice explains that the sole author of the paper, “Diabetic Sensory and Motor Neuropathy,” reported incorrect doses for several medications, and received royalties for the tool to measure quality of life used in the paper. The author told us all the declarations were “discussed in detail” between him and the journal, and both parties agreed to the final decision. 

Let’s take a look at the lengthy correction notice — what some of our readers might call a “mega-correction:” Continue reading NEJM quickly corrects disclosure statement, errors in diabetes paper

Two more retractions bring total to 9 for neuroscience duo

Journal of Neuroscience CoverAfter the first author admitted to fraud, his colleagues have retracted a 2013 paper in the Journal of Neuroscience, as well as a 2015 book chapter about working memory.

The retractions come as part of a backstory of pulled papers authored by psychologist Edward Awh and his former graduate student David Anderson when he was based at the University of Oregon in Eugene. The pair retracted four papers last year after Anderson admitted to misconduct during an investigation by the U.S. Office of Research Integrity (and spoke to us about it last July). This led Awh — now based at the University of Chicago in Illinois — to take a second look at the other publications he’d co-authored with Anderson; earlier this year, Awh retracted two others, and informed us more would be coming, including the two most recent publications. 

First, let’s take a look at the retraction note for the Journal of Neuroscience paper, about remembered items and task performance: Continue reading Two more retractions bring total to 9 for neuroscience duo
