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:

Editors-in-chief of math journal resign over controversial paper

Both editors of a math journal have resigned over the decision to publish a controversial paper, which was apparently made without consulting the editorial board.

Last week, the editorial board of EMS Surveys in Mathematical Sciences issued a statement about the paper, saying its acceptance was “a serious mistake.” According to the statement, the two editors-in-chief of the journalNicola Bellomo, a professor at Polytechnic University of Turin in Italy, and Simon Salamon, a professor at King’s College Londonhave “assumed responsibility for these mistakes” and resigned from their position.

However, a spokesperson for the journal told us the paper is not likely to be retracted.

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

“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

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”

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.

Title: Industrial antifoam agents impair ethanol fermentation and induce stress responses in yeast cells

What Caught Our Attention: When authors decide they want to make their articles freely available after they’ve already been published, how should publishers indicate the change, if at all? Recently, Ross Mounce (@rmounce) thought it was odd a Springer journal issued a formal correction notice when the authors wanted to make their paper freely available, and we can’t say we disagree.  As he posted on Twitter:

”Definitely embarrassing:” Nobel Laureate retracts non-reproducible paper in Nature journal

A Nobel Laureate has retracted a 2016 paper in Nature Chemistry that explored the origins of life on earth, after discovering the main conclusions were not correct.  

Some researchers who study the origins of life on Earth have hypothesized that RNA evolved before DNA or proteins.  If true, RNA would have needed a way to replicate without enzymes. The Nature Chemistry paper found that a certain type of peptide — which may have existed in our early history — made it possible for RNA to copy itself.

Jack W. Szostaka professor of chemistry and chemical biology at Harvard University in Cambridge, Mass., who shared the 2009 Nobel Prize in Physiology or Medicine with Elizabeth Blackburn and Carol Greider for their pioneering research on aging—told us he was “incredibly excited” when he “thought we had at least a partial solution to this problem,” which researchers have been working on for over 50 years.  

But in subsequent experiments, Tivoli Olsen — a member of Szostak’s lab — could not reproduce the 2016 findings. When she reviewed the experiments from the Nature Chemistry paper, she found that the team had misinterpreted the initial data: The peptide in question did not appear to provide an environment that fostered RNA replication.

The errors were “definitely embarrassing,” Szostak told us: Continue reading ”Definitely embarrassing:” Nobel Laureate retracts non-reproducible paper in Nature journal

When publishers mess up, why do authors pay the price?

Springer has retracted two papers, which appeared online earlier this year in different journals, after discovering both were published by mistake.

A spokesperson at Springer explained that the retractions are “due to a human error.”

According to one of the retraction notices, published in Archive for Mathematical Logic, the paper had not yet undergone peer review and the author plans to resubmit his paper to the journal. The other retraction notice, published in Arabian Journal of Geosciences, simply states that an “error in the submission system” is to blame. Unfortunately, in both cases the authors now have a retraction on their record, seemingly through no fault of their own.

Neither notice indicates what publisher glitches led to the premature publications. We asked the spokesperson for clarity, but she did not elaborate. When asked whether Springer has made changes to prevent these errors from happening again, the spokesperson said:

Title: Exploration of inhibitory mechanisms of curcumin in lung cancer metastasis using a miRNA- transcription factor-target gene network

What Caught Our Attention: The researchers were studying how curcumin, a component of the spice turmeric, can inhibit lung cancer metastases. But upon learning that the primary material had been expired at the time of testing (and realizing they were unable to repeat their experiments), the researchers pulled their paper. Expiration dates do have safety factors built in, but attention to such details is imperative in research.  Continue reading Caught Our Notice: What if you find out a paper relied on expired herbal supplement?
