“Rigging of the peer-review process” kills parasite paper

s13369083k

A paper on nematode parasites appears to have been infected with a nasty strain of a publishing problem known as fake peer review. By our count, the phenomenon has felled approximately 250 papers in total.

The affected review, “The important role of matrix metalloproteinases in nematode parasites,” explores a type of enzyme secreted by the parasite. Published in Helminthologia, it’s been cited once, according to Thomson Scientific’s Web of Knowledge.

Unfortunately, the retraction note doesn’t give us too many details about how the peer review process was manipulated:

Danish neuroscientist sentenced by court for lying about faked experiments

court caseIn a rare development, neuroscientist Milena Penkowa has been sentenced by a Danish court for faking data.

The ruling, from the Copenhagen City Court, resulted from Penkowa’s publication of her 2003 thesis describing experiments that she never carried out. The court “placed weight” on the fact that she didn’t just commit fraud, but “systematically supplied false information” to avoid being caught, according to the court’s notice.

The sentence is nine months of “conditional imprisonment,” according to our translation; The University Post, a newspaper affiliated with the University of Copenhagen, calls it a “nine month suspended sentence with a two years probation.”

Here’s the full summary of the new ruling, from the Copenhagen City Court (translated from Danish by One Hour Translation):

Investigation finds “careless data workup” in alcoholism drug paper

S00142999

An investigation at Karolinska Institute has led to the retraction of a paper about drug treatments for alcoholics, after concluding the article contains a “very careless data workup.”

The paper, “Memantine enhances the inhibitory effects of naltrexone on ethanol consumption,” found that the drug memantine (normally used to treat Alzheimer’s) enhances the effects of naltrexone in rats, which blocks the high of alcohol.  It was published in the European Journal of Pharmacology and has been cited 10 times, according to Thomson Scientific’s Web of Knowledge.

However, its conclusion is now “unreliable,” according to the retraction note:

German dep’t head reprimanded for not catching mistakes of co-author Lichtenthaler

Holger Ernst
Holger Ernst

The head of a department at WHU — Otto Beisheim School of Management has been charged with “severe scientific misconduct” for not spotting many of the data irregularities of his co-author Ulrich Lichtenthaler, which have ultimately led to 16 retractions.

According to a news release describing a WHU investigation (which we had translated using One Hour Translation), Holger Ernst did not neglect his supervisory duties, but, as a co-author on many of the retracted papers, he should have been more aware of the data issues in Lichtenthaler’s work: Continue reading German dep’t head reprimanded for not catching mistakes of co-author Lichtenthaler

1+1 “identical” math papers = retraction

homeHeaderTitleImage_en_USA paper on an equation useful in finance has been retracted after editors discovered an “identical” version had been published in another journal.

The paper, “On the Parametric Interest of the Black-Scholes Equation,” was published in the Thai Journal of Mathematics. According to the introduction, that equation has a practical use:

In financial mathematics, the famous equation named the Black-Scholes equation plays an important role in solving the option price of stocks

(According to The Guardian, it was “The mathematical equation that caused the banks to crash.”)

4th ORI-flagged paper by Oregon student is retracted

home_cover (2)The last of four papers containing data falsified by University of Oregon neuroscience student David Anderson has been retracted.

When the Office of Research Integrity report flagging the papers came out in July, Anderson told us he “made an error in judgment,” and took “full responsibility” for the misconduct.

The newly retracted paper, “A common discrete resource for visual working memory and visual search,” published in Psychological Science, has been cited 28 times, according to Thomson Scientific’s Web of Knowledge. According to the abstract, it demonstrates a possible link between working memory and the ability to “rapidly identify targets hidden among distractors.”

But according to the retraction note, Anderson produced “results that conformed to predictions” by “removing outlier values and replacing outliers with mean values”  in some of the data.

Here’s the retraction note in full:

50 years later, is it time to retract a retraction by a Nobel prize-winning author?

Georg Wittig
Georg Wittig

It’s not often that an article is retracted only to be later proven correct. But that may have happened this past summer in the chemistry literature.

In July, a group of researchers recapitulated an experiment largely similar to one that Nobelist Georg Wittig had performed – and subsequently retracted — decades earlier. Their findings suggest Wittig may actually have gotten it right the first time.

On July 27, Peter Chen of ETH Zurich and colleagues published an article online in the journal Angewandte Chemie International Edition that describes a new method for appending a carbon atom to an unsaturated hydrocarbon to create a three-membered ring – a useful chemical transformation known as cyclopropanation. Yet, it was not the first time researchers had reported such a process. As Chen and his colleagues note in the Israel Journal of Chemistry, Georg Wittig of the Ruprecht-Karls-Universität Heidelberg (who would go on to win the chemistry Nobel Prize in 1979) and Volker Franzen reported a similar reaction in 1960 in Angewandte Chemie, a German-language publication.

Mirror image in plant study flagged on PubPeer grows into retraction

djs_mpmi_28_9_cover-online.inddA 2010 paper on plant fungus has been retracted after a comment on PubPeer revealed that a study image had been flipped over and reused to represent two different treatments.

In May, a commenter pointed out the plants in Figure 2a of the paper in the journal Molecular Plant-Microbe Interactions “look remarkably similar.” A commenter writing under the name of corresponding author, Yukio Tosa at Kobe University in Japan, posted a response two days later agreeing with the assessment and stating that the paper should be retracted.

The notice reads: Continue reading Mirror image in plant study flagged on PubPeer grows into retraction

Biologist banned by second publisher

TF

Plant researcher Jaime A. Teixeira da Silva has been banned from submitting papers to any journals published by Taylor & Francis. The reason: “continuing challenges” to their procedures and the use of “inflammatory language.”

This is the second time Teixeira da Silva has been banned by a publisher —  last year Elsevier journal Scientia Horticulturae told him that they refused to review his papers following “personal attacks and threats.”

Apparently, Taylor & Francis has too become frustrated with Teixeira da Silva’s communication strategy. Anthony Trioli, from Taylor & Francis, told Teixeira da Silva in an email (to which Teixeira da Silva copied us on his reply) that they would no longer accept his papers:

PLOS Genetics updates flagged paper with expression of concern

Screen Shot 2015-09-15 at 2.15.29 PM

PLOS Genetics has upgraded a notice on a paper to an expression of concern, raising the count for author chemist Ariel Fernandez to one retracted paper, and three expressions of concern.

The journal published “Protein Under-Wrapping Causes Dosage Sensitivity and Decreases Gene Duplicability” in 2008. In 2013, Fernandez corrected it, claiming that the work was not actually funded by the U.S. National Institutes of Health, as the original paper had said. The paper has been cited 33 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the expression of concern in full, which was published on September 14:
