Plant scientist Voinnet’s correction count grows to 22

nature structure molecular biologyWe have found another correction for high-profile plant scientist Olivier Voinnet, bringing his total count to 22. Voinnet, who works at ETH Zurich, also has seven retractions, a funding ban, and a revoked award.

Voinnet’s most recent corrections involve problems with figures; the same issue is cited in this latest correction notice, for “Competition for XPO5 binding between Dicer mRNA, pre-miRNA and viral RNA regulates human Dicer levels.”

The correction notice in Nature Structural & Molecular Biology, issued earlier this year, explains:

Philosophy journal spoofed, retracts hoax article

A philosophy journal that focuses on the teachings of philosopher Alain Badiou has apparently fallen victim to yet another Sokal hoax, and has retracted a fake article submitted by authors trying to expose the publication’s weaknesses.

The paper, “Ontology, Neutrality and the Strive for (non-)Being-Queer,” attributed to Benedetta Tripodi of the Universitatea Alexandru Ioan Cuza in Romania, is apparently the work of two academics, who submitted the absurd article to Badiou Studies to expose its lack of rigor in accepting papers.

Just a quick look at some of the text of the fake paper exposes its peculiarities. Here are the first few lines of the abstract: Continue reading Philosophy journal spoofed, retracts hoax article

Does this scientific image look familiar? It’s from a catalog

cover (4)There’s something strange about a 2008 paper on the role of nicotine receptors in promoting lung cancer: One of the western blot analyses looks like a version of an image from a commercial catalog.

A commenter on PubPeer pointed out the similarities between an image in “Role of α7-nicotinic acetylcholine receptor in human non-small cell lung cancer proliferation,” which was published in Cell Proliferation, and one used to promote an enzyme sold by Cell Signaling Technology.

Unfortunately, if the images are indeed the same, we can’t tell for certain who copied from whom. But a representative of the company told us it generates its own images, and this one was likely created before the paper was published. The last author — for whom we’ve found three other retractions — denied that the paper copied the image.

Here’s the panel from the paper, which was published in 2008: Continue reading Does this scientific image look familiar? It’s from a catalog

Seralini paper released by predatory publisher is plagiarized by predatory journal

ijtra-logoA 2012 paper co-authored by Gilles Seralini, who has published controversial research showing the dangers of genetically modified foods, has been plagiarized by another researcher.

The 2016 paper, published in the International Journal of Technical Research and Applications, has not been retracted, but the text comparison is fairly obvious.

It’s a case of intra-predatory crime: the International Journal of Technical Research and Applications is on the list of predatory journals compiled by Jeffrey Beall, and the Seralini paper appeared in the Journal of Environmental Protection, which is published by Scientific Research Publishing, which Beall considers to be a predatory publisher.

Here’s the abstract from Seralini’s 2012 paper, “Glyphosate Exposure in a Farmer’s Family:” Continue reading Seralini paper released by predatory publisher is plagiarized by predatory journal

EMBO takes back Voinnet’s award, investigates other awardee who just lost a Nature Genetics paper

Screen Shot 2016-01-28 at 11.41.20 AMEMBO has taken back an award given to beleaguered plant biologist Olivier Voinnet in 2009, and is investigating a recent grantee who had a paper retracted from Nature Genetics yesterday.

The European Molecular Biology Organization (EMBO) “promotes excellence in the life sciences” in Europe, in part by awarding prizes to promising young scientists. Voinnet and Sonia Melo earned their awards by exhibiting potential as young scientists studying genetics — of plants and cancer, respectively — but now EMBO is skeptical of the papers that formed the basis of their applications.

Melo’s Installation Grant from EMBO was announced just last month, and consists of 50,000 Euros annually for three to five years. She is currently based at the University of Porto, in Portugal.

Voinnet’s problems are well-documented on this blog — 21 corrections, seven retractions, and two investigations. Earlier this week, we reported that the Swiss National Science Foundation had cut off Voinnet’s funding, and banned him for three years.

Swiss funding agency cuts off Voinnet, bans him for 3 years

The Swiss National Science Foundation has stopped funding prominent plant scientist Olivier Voinnet, following months of questions about his work that have culminated in multiple retractions and corrections.

The agency confirmed to us that it has also banned Voinnet from seeking funding from the SNSF for three years.

We asked the SNSF the amount of funding Voinnet was receiving from SNSF at the time of this decision. They told us it was 1.25 million Swiss francs, equivalent to roughly the same in U.S. dollars.

By our count, Continue reading Swiss funding agency cuts off Voinnet, bans him for 3 years

Science publishes Voinnet’s 19th, 20th, and 21st corrections

351-6271-coverProminent plant biologist Olivier Voinnet has issued three more corrections in this week’s issue of Science.

Collectively, the papers have earned more than 1400 citations, according to Thomson Scientific’s Web of Knowledge.

By our count, he’s now at 21 corrections and seven retractions, following months of questions about his work. He’s been the subject of an investigation that found he “breached his duty of care,” and another which found evidence of scientific misconduct.

One correction goes against the recommendation of the ETH Commission to retract the paper for “well documented intentional manipulations.” According to the correction note, the incorrect figures did not “alter the data in any material way that could be construed to benefit the results and their conclusions.” That correction is the only one of the three for which Voinnet takes full responsibility.

The other two corrections place the responsibility on  Continue reading Science publishes Voinnet’s 19th, 20th, and 21st corrections

Voinnet’s notice count grows, as he notches his 18th correction

home_coverOlivier Voinnet, a high-profile plant scientist at ETH Zurich, has earned a mega-correction. It wrapped up a rough year for the biologist, which included his seventh retraction, and a CNRS investigation that found evidence of misconduct.

This latest correction, to a paper on the mechanisms behind RNA silencing in Arabidopsis, was published in RNA. The 2007 paper has been cited 101 times, according to Thomson Scientific’s Web of Knowledge. The corrigendum modifies three figures in total.

The notice is long, so we’re not going to post the whole thing here. The first error in “Transitivity in Arabidopsis can be primed, requires the redundant action of the antiviral Dicer-like 4 and Dicer-like 2, and is compromised by viral-encoded suppressor proteins” is a clarification to a legend:

Authors retract chemistry letter after new data reveal problems in reaction, structure

title

The authors of a letter describing the synthesis of ketonitrones have retracted it, after new data showed that they incorrectly reported the product structures and the reaction mechanism.

We’re not sure what exactly went wrong with the original data in the letter, “Transition-Metal-Catalyzed Ring Expansion of Diazocarbonylated Cyclic N-Hydroxylamines: A New Approach to Cyclic Ketonitrones,” published in Organic Letters. 

Here’s the reaction that the paper reported, from the abstract:

Voinnet retracts highly cited paper, bringing his total to 7

coverOlivier Voinnet, a well-known plant scientist at the ETH in Zurich, has notched his 7th retraction for a highly cited paper. The 2003 paper was pulled when “additional image manipulations” came to light after The Plant Journal issued a correction earlier this year.

The retraction follows an investigation into — and then retraction of — several other papers co-authored by Voinnet. The authors originally corrected the paper after they learned one image had been duplicated, and repeating the experiment found the “same interpretation and conclusions” held true. But when the corresponding author learned of additional “data manipulation,” they decided to retract the paper altogether.

Here’s the retraction notice for “An enhanced transient expression system in plants based on suppression of gene silencing by the p19 protein of tomato bushy stunt virus:”
