Mol bio paper pulled by PLOS following investigation into figures

with 6 comments

Screen Shot 2015-11-17 at 11.58.47 AMPLOS Biology has retracted a paper about the molecular details of β-catenin expression following an investigation by the first author’s institution in Italy.

The investigation, by the Istituto Nazionale per la Ricerca sul Cancro, found that there were multiple “figure anomalies.” According to the note:

An explanation of inadvertent error was given for some of the issues identified, while for two issues, a satisfactory explanation could not be provided.

First author Roberto Gherzi says none of his co-authors helped prepare the figures. The authors maintain that the conclusions are unaffected, but that assurance wasn’t enough for the journal. Here’s more from the lengthy retraction note, which provides some backstory on the “serious concerns” regarding the data:

Danish neuroscientist sentenced by court for lying about faked experiments

with 8 comments

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 Posta 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):

Authors’ pharma ties cause Cochrane to withdraw two diabetes reviews

with 5 comments

Cochrane_LogoThe Cochrane Library has withdrawn two reviews evaluating the effectiveness of diabetes treatments because some of the papers’ authors work with pharmaceutical companies.

Bianca Hemmingsen, first author on both reviews, told us the Cochrane Library asked the authors to remove the researchers with ties to pharma, but after one “refused to withdraw,” both papers were pulled entirely.

However, Hemmingsen insists that their employment had no impact on either paper.

This breaks the typical mold for Cochrane withdrawals, which are usually only pulled to indicate updates and show that older reviews no longer represent the best evidence.

“Goodbye…”?: Editor pulls farewell editorial after deeming it “inappropriate”

without comments

3We’ve unearthed a retraction of an editorial titled “Goodbye…”, pulled from Cognition, Technology & Work by its retiring editor after he decided it was “inappropriate.”

The original text is not online. The note in its place reads, in full:

This article has been retracted due to unintended publication.

The author of the editorial is psychologist Erik Hollnagel, based at the University of Southern Denmark, who left the journal after a decade. Interestingly, his own research includes studies of “When Things Go Wrong” (per the title of one of his book chapters), ranging from financial crises to the Fukushima disaster.

The error that led to this reaction seems tiny, in comparison. Hollnagel explains:

Yup, this happened: “Mystery” writer impersonated cardiovascular pathologist, penned published letter

with 6 comments

A 2014 letter in the Journal of the American College of Cardiology has been retracted because editors aren’t sure who wrote it.

“Can Grayscale IVUS Detect Necrotic Core-Rich Plaque?”, a letter on the potential of intravascular ultrasound, was submitted under the name of a researcher at the University of Copenhagen, Erling Falk. The paper was sent with a Gmail account (a technique used by some academics to conduct fake peer reviews), and editors communicated with the author through the acceptance process.

Shortly after the letter was published, Erling Falk of Aarhus University contacted the journal and asked who wrote the letter. They discovered that nobody by that name worked at the University of Copenhagen and emails to the author’s Gmail address went unanswered. So the journal issued a retraction.

Here’s the complete notice:

Danish high court clears Pedersen in misconduct case

with 17 comments


Klarlund Pedersen

Lawyers one, scientists nil.

Danish judges have overruled scientists in that nation, concluding that a panel of experts erred in finding that physiologist Bente Klarlund Pedersen, of the University of Copenhagen, was guilty of misconduct.

Last September, Pedersen announced that she would fight the ruling of the Danish Committees on Scientific Dishonesty (DCSD, Danish acronym UVVU), which had said she had committed misconduct in four of 12 articles it had examined.

As we reported then, Pedersen’s case is tied to that of another Copenhagen scientist, Milena Penkowa, with whom she had collaborated and who also has been found guilty of scientific misdeeds. (The new ruling does not address Penkowa.) Read the rest of this entry »

He shoots, he…misses! Soccer injury paper gets red card for data errors

without comments

jsmsThe authors of a 2014 paper on soccer injuries have forfeited their publication after revealing that the foundation of the work was based on faulty data. (Look, we could have written about letting air out of balls, yadda yadda, but the Super Bowl has come and gone.)

The article, which appeared in the Journal of Science and Medicine in Sport, was written by a group in Denmark and Qatar led by Cristiano Eirale, a sports medicine researcher at the Aspetar-Qatar Orthopedic and Sports Medicine Hospital, in Doha. It showed goalies had a lower rate of injuries during training than field players.

Trouble was, someone called a foul.

Danish committee rejects much of Klarlund Pedersen’s appeal of misconduct findings

without comments

Klarlund Pedersen

The Danish Committees on Scientific Dishonesty (DCSD, Danish acronym UVVU) has partially reversed a December 2013 finding of misconduct against a scientist in Denmark, but has upheld most of its ruling.

Bente Klarlund Pedersen, whose case was tied up with that of Milena Penkowa, another scientist in Denmark found guilty of misconduct, committed misconduct in four of 12 articles examined, not six, the DCSD said in a statement last week.

Here’s the English summary (the DCSD does not name scientists under investigation publicly, but Pedersen has confirmed this is about her): Read the rest of this entry »

Authors retract paper “confirming” that narcolepsy is an autoimmune disease

with 6 comments

stmA group of researchers at Stanford and elsewhere is retracting a 2013 paper that another scientist told Nature was “one of the biggest things to happen in the narcolepsy field for some time.”

The Science Translational Medicine paper caused a buzz because it claimed to show that narcolepsy was an autoimmune disease. Here’s the notice: Read the rest of this entry »

Penkowa-Pedersen paper retracted nearly three years after being subjected to Notice of Concern

with one comment

faseb journalWe have an update on the complicated story of Milena Penkowa and Bente Klarlund Pedersen.

Two papers coauthored by the pair — who have both been found guilty of scientific dishonesty by the Danish Committees on Scientific Dishonesty — have been retracted by the FASEB Journal.

Here’s one notice (both are unfortunately behind a paywall): Read the rest of this entry »
