Not every study contains accurate information — but over time, some of those incorrect findings can become canonized as “fact.” How does this happen? And how can we avoid its impact on the scientific research? Author of a study published on arXiv in September, Carl Bergstrom from the University of Washington in Seattle, explains how the fight over information is like a rugby match, with competing sides pushing the ball towards fact or falsehood — and how to help ensure the ball moves in the right direction.

A paper on chemical safety was accepted one day after submission. Was it peer reviewed?

Toxicology Reports

Some scientists raise their eyebrows when they see a paper was accepted only a day or two after being submitted — which is exactly what happened during an academic debate over a controversial topic: e-cigarettes.

In 2015, a group of Harvard researchers published a paper in Environmental Health Perspectives suggesting the flavoring added to e-cigarettes could be harmful; the next year, another group criticized the paper in the journal, noting the chemicals may not be as dangerous as the original paper claimed. The Harvard researchers then fired back, noting that the criticism cited two papers that were accepted within one and three days after submission, and therefore “appear not to have been peer reviewed.”

However, a little digging suggests otherwise. 

The editor of the journal that published both of the cited papers in question — Toxicology Reports — told us the papers were peer reviewed at Toxicology, but transferred to his journal as part of a process known as portable peer review.

Here are more details from Lawrence Lash, editor-in-chief of Toxicology Reports from Wayne State University School of Medicine in Detroit, Michigan: Continue reading A paper on chemical safety was accepted one day after submission. Was it peer reviewed?

Oh, well — “love hormone” doesn’t reduce psychiatric symptoms, say researchers in request to retract

psychiatry-research

It turns out, snorting the so-called “love hormone” may not help reduce psychiatric symptoms such as depression and anxiety.

At least, that’s the conclusion the authors of a 2015 meta-analysis, which initially found intranasal doses of oxytocin could reduce psychiatric symptoms, have now reached. After a pair of graduate students pointed out flaws in the paper, the authors realized they’d made some significant errors, and oxytocin shows no more benefit than placebo.

First author Stefan Hofmann from Boston University in Massachusetts explains further in a lengthy letter he sent to Psychiatry Research, which he passed on to us: Continue reading Oh, well — “love hormone” doesn’t reduce psychiatric symptoms, say researchers in request to retract

Oops — journal retracted the wrong article

journal-of-human-reproductive-sciences

Sometimes you have the right guy, but charge him with the wrong crime — like nabbing someone for not using a turn signal after he just ran through a red light.

A reproductive sciences journal has admitted to mistakenly retracting the wrong article last year — and is now pulling the previously issued retraction notice, along with retracting a different paper by the same author.

K. P. Suresh, author of both studies (the previously pulled one and the newly retracted one) from the National Institute of Veterinary Epidemiology and Disease Informatics in Bengaluru, Karnataka, India, appealed the journal’s 2015 decision to retract his previous paper. As we reported at the time, Suresh argued that his 2012 paper was “entirely different” from the study it is said to have plagiarized from. It turns out, he may have been right, because now the journal has pulled a different paper of his, published in 2011.

According to one of the notices, the Journal of Human Reproductive Sciences previously retracted the incorrect paper due to “technical errors.”

In both cases, the journal cited the reason for retraction as “duplicity of text.”

The journal has now issued another retraction notice for the previously published notice, which reads: Continue reading Oops — journal retracted the wrong article

Physics journal retracts paper without alerting author

annals-of-physics

An Elsevier journal has angered an author by removing his study without telling him.

After spending months asking the journal why it removed the paper — about a heavily debated theorem in physics — and getting no response, the author threatened to seek damages from the journal and publisher for “permanently stigmatizing” his work. Yesterday, an Elsevier representative told the author what happened: Experts told the journal the paper had a major mistake, so the journal decided to withdraw the study, but failed to tell the author due to an “internal error.”

That explanation didn’t satisfy study author Joy Christian, scientific director of the Einstein Centre for Local-Realistic Physics in Oxford, UK, who has demanded the journal either republish the article or remove it and return the copyright to him, or he will pursue legal action.

Here’s the cryptic publisher’s note for “Local causality in a Friedmann–Robertson–Walker spacetime:” Continue reading Physics journal retracts paper without alerting author

Ecology journal flags carnivore paper under investigation

journal-of-applied-ecologyAn ecology journal has issued an expression of concern (EOC) for a recently published study, citing an institutional investigation about the data and conclusions.

According to the notice — issued by the Journal of Applied Ecology — the author’s institution in South Africa has received a report from an independent examiner. The editors are reviewing the paper — about reducing the impact of lethal carnivores such as black-backed jackals — “in light of this information.”

An official from the journal told us the investigation has to do with “relevant background information” that was not included in the study, published online in December.

Here’s the EOC, published earlier this month: Continue reading Ecology journal flags carnivore paper under investigation

1st retraction for researcher who lost whistleblower lawsuit

microvascular-research

A researcher who was dismissed from Wayne State University — then lost a whistleblower lawsuit against it — has logged his first retraction.

In 2012, after Christian Kreipke was dismissed from Wayne State, he filed a lawsuit, alleging that the institution had defrauded the U.S. government of $169 million in research funding. A judge dismissed the case in 2014, noting Kreipke cited “no specific facts,” and as a public university, Wayne State had immunity as an “arm of the state.”

The university’s president has said Kreipke was fired due to misconduct — not his whistleblowing, according to Courthouse News Service. 

Now, a retraction has appeared for Kreipke in Microvascular Research, citing discrepancies between the original data and what was reported in the paper. 

Here’s the retraction notice: Continue reading 1st retraction for researcher who lost whistleblower lawsuit

Cell Press won’t retract papers despite one author confessing to fraud

Screen Shot 2016-08-03 at 18.54.35Cell Press journals will not be retracting two papers that were flagged with expressions of concern (EOCs) in April after one author claimed to have manipulated some experiments.

In a strange turn of events, as we previously reported, the study’s corresponding author refuted the claims of the author who confessed to fraud, citing concerns about his “motives and credibility.” Since then, two independent labs repeated the authors’ experiments, and “largely confirm” the central conclusions of a Cell paper, but were inconclusive regarding a paper in Molecular Cell. Regardless, in both cases, the journals have decided to take no further action. 

Both expressions of concern (and their associated editorial notes) will remain online, as part of the “permanent record,” a Cell Press spokesperson told us.

The spokesperson added more about the investigation process: Continue reading Cell Press won’t retract papers despite one author confessing to fraud

Data were “fraudulently obtained” in epilepsy paper, probe finds

brain-research-bulletinA brain research journal has retracted a 2016 study about epilepsy after an institutional investigation determined that some of the data were taken from another published paper.

The retraction notice for the study — which appeared in Brain Research Bulletin — cites an investigation by the scientific integrity committee at Tongji University in Shanghai, China, which concluded the authors had engaged in “unethical publishing behavior.”

Here’s the retraction notice for “Clc-2 knockout attenuated experimental temporal lobe epilepsy in mice by tonic inhibition mediated by GABAA receptors:” Continue reading Data were “fraudulently obtained” in epilepsy paper, probe finds

Error in one line of code sinks cancer study

journl-of-clinical-oncologyAuthors of a 2016 cancer paper have retracted it after finding an error in one line of code in the program used to calculate some of the results.

Sarah Darby, last author of the now-retracted paper from the University of Oxford, UK, told Retraction Watch that the mistake was made by a doctoral student. When the error was realized, Darby said, she contacted the Journal of Clinical Oncology (JCO), explained the issue, and asked whether they would prefer a retraction or a correction. JCO wanted a retraction, and she complied.

The journal allowed the authors to publish a correspondence article outlining their new results.

Here’s the lengthy retraction notice, published online last month: Continue reading Error in one line of code sinks cancer study
