5th retraction for Voinnet follows correction, EoC to PLOS Genetics paper

PLOS GeneticsAfter correcting a paper due to problematic figure panels, researchers led by high-profile biologist Olivier Voinnet have now retracted it, after “further analysis of the paper revealed flaws in the interpretation of” another figure.

PLOS Genetics published the retraction notice September 3 for the 2013 paper on the molecular details of embryonic stem cells in mice. First author Constance Ciaudo and Voinnet assume “full responsibility for the mistakes on this paper,” according to the note.

Stem cell researcher Jacob Hanna’s correction count updated to 10

Thanks to some eagle-eyed readers, we’ve been alerted to some corrections for high profile stem cell scientist Jacob Hanna that we had missed, bringing our count to one retraction and 13 errata on 10 papers.

The problems in the work range from duplications of images, to inadvertent deletions in figures, to failures by his co-authors to disclose funding sources or conflicts of interest. Hanna is the first or last author on 4 of the papers, and one of several on the rest.

First up, a correction to a Cell paper on which Hanna is the first author:

A mess: PLOS mistakenly publishes rejected ADHD-herbicide paper, retracts it

logoPLOS One has retracted a paper that links the most commonly used herbicide to ADHD, after it was “published in error.”

According to the note, the paper was “editorially rejected following peer review and consultation with the Editorial Board,” but ended up going through the production process anyway.

When we contacted the authors, they filled us in with more details.

Following criticism, PLOS removes blog defending scrutiny of science

plos_logoCommunity blog PLOS Biologue has pulled a post by journalists Charles Seife and Paul Thacker that argued in favor of public scrutiny of scientists’ behavior (including emails), following heavy criticism, including from a group and scientist mentioned in the post.

Their reasoning: The post was “not consistent with at least the spirit and intent of our community guidelines.”

The original post, published August 13, is no longer available online, but you can read it here. In the piece, Seife and Thacker lament what they call a recent backlash against transparency in science: Continue reading Following criticism, PLOS removes blog defending scrutiny of science

Investigation triggers retraction for biochem paper

PLOS BiologyA paper has been retracted from PLOS Biology for duplicating lanes and incorporating others that “came from an unrelated experiment that had already been published.”

According to the retraction notice, first author Laura Cerchia says that the mistakes came “as a consequence of incorrect incorporation of representative blots.” Cerchia — along with her supervisor, study author Vittorio de Franciscis — “apologizes for this.” None of the other authors were “involved in the preparation of these figures, and there is no concern about the results that they contributed.”

Cerchia maintains that the paper’s conclusions are still valid, but the remaining authors write that the issues undermines their confidence in the results. According to the notice, the retraction is a result of “an institutional inquiry” at the Consiglio Nazionale delle Ricerche (CNR) in Rome, where Cerchia and de Franciscis are both based.

The notice tells the rest of the story:

Author’s ties to NFL lead to correction for review that cast doubt on brain risk from sports

PLOS ONE

A review paper that suggested the degenerative brain disease that’s striking former football players may not be tied to contact sports has been corrected to reveal the first author spent decades working for the National Football League.

The correction appears in a review in PLOS ONE about chronic traumatic encephalopathy – the degenerative brain disease that was the basis of a $765 million settlement for former NFL players, along with a number of similar lawsuits. It fixes incorrect statements and adds conflicts of interest, including those with with first author Joseph Maroon, who spent more than 30 years working with the NFL and seven for the wrestling group the WWE.

It appears as if all the original paper declared was that Maroon was an “unpaid consultant” to the Pittsburgh Steelers. But apparently there was a lot more to it, according to the notice:

Corrections (and one EoC) propagate for distinguished plant biologist, Olivier Voinnet

There may be some deeply rooted issues in the work of high-profile plant biologist Olivier Voinnet, biology department research director at ETH in Zurich. Corrections have continued to pile up months after his work was hit with a barrage of criticism on PubPeer. We’ve tracked a total of seven corrections over the past five months (not including the April retraction of a 2004 paper in The Plant Cell). One of the corrected papers also received an Expression of Concern this week.

Collectively, the corrected papers have accumulated more than 1200 citations.

In January, Voinnet said he planned to correct multiple papers, after receiving “an anonymous email.”

One of the recent corrections we found is for a 2003 article in The Plant Journal, “An enhanced transient expression system in plants based on suppression of gene silencing by the p19 protein of tomato bushy stunt virus,” which details using proteins from a tomato virus to help alter gene expression. The study has been cited 862 times, according to Thomson Scientific’s Web of Knowledge. Here’s the correction notice, posted June 8:

It’s a man’s world — for one peer reviewer, at least

We’ve written quite a lot about the perks and pitfalls of the peer review system, but one thing we never really touched on was the risk that a reviewer might be … well, not to put too fine a point on it: a dope.

But Fiona Ingleby can speak to that. Ingleby, a postdoc in evolutionary genetics at the University of Sussex in the United Kingdom, co-wrote an article on gender differences in the transition from PhD-dom to postdoc land and submitted it to a journal for consideration. What she heard back was lamentably ironic — and grossly sexist. Continue reading It’s a man’s world — for one peer reviewer, at least

Former postdoc suing lab head for publishing paper he says he wrote, without his name

plos biologyA pharmaceutical researcher is suing his postdoctoral advisor and former business partner, accusing him of publishing a paper in PLoS Biology they wrote together, and removing him as an author.

According to the complaint, Andrew Mallon and John Marshall co-founded a company, Ardane Therapeutic, to commercialize a potential therapy that Mallon discovered for Angelman Sydrome, a developmental disorder characterized by cognitive impairment and autism.

In 2011, the two, along with several other members of Marshall’s lab at Brown University, wrote and submitted a paper to Neuron (listing Mallon as the first author), which was not accepted. Shortly after submission, “Mallon and Marshall had a falling out,” the complaint says — specifically, they “disagreed about how Ardane should be operated and about the required standards of legal and ethical conduct.” Mallon left the lab and founded his own company, Calista Therapeutics.

In 2013, Marshall and his team published a paper in PLoS Biology, “Impairment of TrkB-PSD-95 Signaling in Angelman Syndrome,” that had some passages taken almost verbatim from the Neuron submission, the complaint says, but Mallon was not included as an author. According to the lawsuit:

PLoS ONE mega-correction, but no retraction, for researcher who sued diabetes journal

PLoS ONE has just issued a 12-figure correction on a paper by Mario A. Saad, who sued the American Diabetes Association unsuccessfully in an attempt to prevent it from retracting four papers in its flagship journal Diabetes.

The corrections include taking out Western blots copied from another Saad paper, as well as several figures where the bands were “misplaced.”

PubPeer commenters suggest this may not be enough, calling seven additional figures into question. Continue reading PLoS ONE mega-correction, but no retraction, for researcher who sued diabetes journal
