PNAS retraction weakens theory that fish travel with siblings

In 2016, researchers at Oregon State University published a paper in PNAS that surprised the research community. They showed that certain fish species travel with their siblings — even fighting against the currents of the Pacific Ocean to stay together.

Needless to say, the research community was skeptical, given how difficult a feat this would be. And their skepticism appears to have been warranted.

Recently, the authors — led by Su Sponaugle — retracted the paper, saying a re-analysis of their data using newly developed research tools has erased their confidence in the results. According to Sponaugle, the quick reversal was thanks to the new technology and open data sharing, which led their findings to be successfully challenged within months of publication. She said her team conducted the study with the “best available knowledge we had at the time,” including what they thought were the most advanced tools available to them:

Author wins judgment against Elsevier in lawsuit over retraction

The author of a 2009 commentary exploring “sexually specific infanticide” in bears has won a judgment against Elsevier for using “untruthful and unverified” language in a 2011 retraction notice.

The last author, Miguel Delibes, who filed the suit in 2014, explained that the judge ruled he should accept the journal’s decision to retract his paper, but “confirmed that my honorability had been damaged” by the false accusation in the original retraction notice. According to a new note on the paper from the publisher, the court required the journal to publish part of its ruling to correct the record.

Caught Our Notice: Oops — 10-fold error reverses heart warning for Ghanaians

Title: Ghanaians Might Be at Risk of Inadequate Dietary Intake of Potassium

What Caught Our Attention: Potassium-rich diets are thought to be “heart-healthy,” and after examining the average dietary habits of Ghanaian adults, researchers determined the average potassium (K) intake to be well below global standards.  However, the authors’ calculations of potassium intake per capita were too low by factor of 10, resulting in the incorrect conclusion that the average potassium intake was only 856 mg per day, an amount substantially lower than the World Health Organization (WHO) recommendation of 3510 mg/day.  The new calculations show an average K intake of 8,560 mg/day, well over the WHO guideline.  

We asked the corresponding author, David Oscar Yawson, about the source of the error, and he responded:

Title: Endotoxaemia during left ventricular assist device insertion: relationship between risk factors and outcome

What Caught Our Attention: Robert J. Frumento first caught our notice in 2013, as a coauthor on a paper retracted with a nonspecific reference to author misconduct.  Three years later, Frumento was clearly identified as having fabricated data and a master’s degree, and added three retractions to his name. Now he’s got a fifth retraction, this one citing missing data and a lack of proof that data blinding was performed correctly.   Continue reading Caught Our Notice: Columbia researcher up to five retractions

University requests 4th retraction for psychologist under fire

Jens Förster

The University of Amsterdam has requested another retraction for a prominent social psychologist, after reviewing the dissertations he supervised while at the university.

The university made the announcement this week after reviewing the theses supervised by Jens Förster, whose own work has been subject to considerable scrutiny.

The results of this investigation come more than two years after an initial probe into Förster’s work, which found several of his papers likely contained unreliable data; three of these papers have been retracted and four have received expressions of concern. Förster, who recently left his position at Ruhr-Universität Bochum in Germany to start a private psychology practice, has always maintained that he did not manipulate his data. In 2015, he turned down a professorship, citing the toll the investigation had taken. Continue reading University requests 4th retraction for psychologist under fire

“This is about saving kids’ lives:” Authors update pivotal car seat safety results

A BMJ journal has published an updated analysis of a 2007 paper that shaped current car seat safety recommendations, which reports less conclusive findings about the safest way to install the seat.

The updated analysis follows an expression of concern the journal Injury Prevention added to the paper in June 2017, after the authors and an outside expert could not replicate the results.

The 2007 paper made a big claim: Children ages one to two years old are five times more likely to sustain serious injuries in a crash when restrained in a forward-facing car seat than a rear-facing seat.

Benjamin Hoffman, a professor of pediatrics at Oregon Health & Science University in Portland who was not involved in the 2007 research, told us: Continue reading “This is about saving kids’ lives:” Authors update pivotal car seat safety results

Mathematician protests retraction, alleging “manhunt”

A math journal has retracted a 2015 paper after three outside experts informed the editors that “the paper contains errors which invalidate its main results.”

According to the retraction notice, published in the July 2017 issue of Manuscripta Mathematica, the author Ilya Karzhemanov “has not admitted to the alleged errors and disagrees with the retraction.”

It’s unclear when exactly the paper was retracted, but Karzhemanov, now associate professor at the Moscow Institute of Physics and Technology, posted the now-retracted paper on arXiv in June 2017 and explained his “strong disagreement” with the retraction: Continue reading Mathematician protests retraction, alleging “manhunt”

Caught Our Notice: A retraction that is “useful for investigators”

Title:  Yeast CAF-1 assembles histone (H3-H4) 2 tetramers prior to DNA deposition

What Caught Our Attention: Informative retraction notices can be infrequent, but rarer still are notices that fulfill an oft-ignored function: To be a source of learning for others in the field. Here, the authors offer a nearly 800-word “detailed description of the issues” with “some observations that may be useful for investigators conducting similar studies.” These authors embraced the retraction process, carefully explaining their findings or the lack thereof, for each figure from their now-retracted paper.     Continue reading Caught Our Notice: A retraction that is “useful for investigators”

Doctor with 9 retractions loses lawsuit over work as expert witness

Cory Toth

A Canadian doctor with nine retractions due to misconduct has lost a court case seeking payment for an expert medical exam he performed in August 2014. The exam took place several months after his university found he had allowed a breach of research integrity in his lab and a month before news of the investigation and his departure from the school made national news in Canada.

On Dec. 5, Cory Toth, a former professor at the University of Calgary (U of C), appeared in an Edmonton, Alberta courtroom as the plaintiff in a lawsuit filed in Provincial Civil Court. The story was first reported by the Edmonton Journal.

Court documents, which we’ve made available here, show that in April 2016 Toth sued Western Medical Assessments (WMA) — the company that hired him to perform the exam, which was used in another case — and Michele Reeves — the lawyer who hired WMA. Toth alleged that he never received payment for his work and sought Can$2,000 (US$1,552) plus interest. In his claim, he said that despite the U of C finding: Continue reading Doctor with 9 retractions loses lawsuit over work as expert witness

Caught Our Notice: How can a publication be a surprise to a corresponding author?

Title: Umbelliferone reverses depression-like behavior in chronic unpredictable mild stress-induced mice via RIP140/NF-κB pathway

What Caught Our Attention: One would think that the corresponding author would have to be aware that they are submitting an article for publication — but apparently not, as this retraction demonstrates. The 2016 paper listed two corresponding authors — along with both of their emails and mailing addresses — but according to the retraction notice, one of them did not give consent “in any form” to the publication. Often, we see authors unaware of the use of their name when their email has been faked, but here, it’s possible the journal simply relied on the other corresponding author for all correspondence.
