Nature tags glacier paper with note of concern due to data mix-up

Nature has tagged a recent paper on the importance of glacial melt to water supply in Asia with an expression of concern (EoC), after receiving a tip that the author had misused some data.

The EoC for “Asia’s glaciers are a regionally important buffer against drought,” published by Hamish Pritchard, a glaciologist at the British Antarctic Survey, came out today. The May 11, 2017 article — which has been cited three times, according to Clarivate Analytics’ Web of Science — considers the contribution of glaciers to water supply in Central Asia and the potential for glacier loss to exacerbate water stress in the region. The paper received limited news coverage when it came out from science sites, including Phys.org.

Pritchard appears to have improperly used a particular data set — an error that was reported to the journal by two outside experts within weeks after the paper was published.  Continue reading Nature tags glacier paper with note of concern due to data mix-up

“It was an honest mistake:” Author retracts and replaces chemistry paper 15 years later

In 2001, Chris Orvig was happy when his team had synthesized a molecule with potential therapeutic applications. He and his colleagues published their findings in a 2002 paper in Inorganic Chemistry.

Over a decade later, Orvig discovered a pivotal error in the paper: The authors had misidentified the compound.

Orvig, a professor of chemistry at the University of British Columbia in Vancouver, told us: Continue reading “It was an honest mistake:” Author retracts and replaces chemistry paper 15 years later

Toronto wife-husband research team lose bid to re-open labs

A pair of Canadian scientists may be running out of options to save their laboratories, which have been permanently closed based on findings of research misconduct.

Sylvia Asa, once the head of the largest hospital diagnostic laboratory in Canada, and her husband and collaborator Shereen Ezzat, have spent almost five years fighting allegations of research misconduct involving data falsification and fabrication in more than a dozen published papers. The couple’s work has been scrutinized by their employer, University Health Network (UHN), a healthcare system affiliated with the University of Toronto, in two investigations. The investigations did not find evidence that Asa or Ezzat were directly involved in image falsification or fabrication; however, they concluded that, as supervisors, they failed to conform to accepted standards and practices as they related to scientific rigor and accountability.

After the first investigation, UHN decided to temporarily close both Asa and Ezzat’s labs. After the second, the UHN decided to make that closure permanent. The couple have had three papers retracted and at least one correction.

Recently, the pair faced yet another setback. After they asked an Ontario court to review two of UHN’s decisions, on July 13, a judge found no fault with either one. Justice Ian Nordheimer, one of three judges who considered Asa and Ezzat’s request, said in his written opinion:  Continue reading Toronto wife-husband research team lose bid to re-open labs

Lancet retracts (and replaces) paper a year after authors report error that changes “all numbers”

In March 2016, researchers in Switzerland and Canada published a meta-analysis in The Lancet, exploring the optimal painkiller and dose for treating pain in knee and hip osteoarthritis. Soon after, the authors were informed of an error that would change “all numbers” in a paper that may influence clinical practice.

The authors contacted The Lancet immediately, in July 2016, to inform them of the issue. Sven Trelle, the paper’s corresponding author, also told us: Continue reading Lancet retracts (and replaces) paper a year after authors report error that changes “all numbers”

Instead of retracting a flawed study, a journal let authors re-do it. It got retracted anyway.

When a journal discovers elementary design flaws in a paper, what should it do? Should it retract immediately, or are there times when it makes sense to give the researchers time to perform a “do-over?”

These are questions the editors at Scientific Reports recently faced with a somewhat controversial 2016 paper, which reported that microRNAs from broccoli could make their way into the nuclei of human cells — suggesting that the food we eat could affect our gene expression.

After the paper appeared, researcher Kenneth Witwer at Johns Hopkins — who was not a co-author — posted comments on PubMed Commons and the paper itself, noting that the authors hadn’t properly designed the experiment, making it impossible for them to detect broccoli microRNAs. 

But instead of retracting the paper, the journal decided to give the authors time to do the experiments again, this time with correctly designed molecular biology tools. When that failed, they retracted it — and as part of the notice, reported the exact opposite conclusion of the original.

Witwer said the authors did a “tremendous job” with the follow-up study, but he still thinks the journal should have retracted the paper immediately. Letting the authors redo it is “a dangerous precedent to set,” he told us:

NEJM issues unusual warning for readers about 1980 letter on opioid addiction

This week, the New England Journal of Medicine issued a type of editor’s note we’ve never seen before, on a highly influential letter published nearly 40 years ago.

Above the one-paragraph letter, which reports data suggesting pain medications are not likely to cause addiction, the journal has added a note warning readers that the letter has been “heavily and uncritically cited” by sources using it to suggest opioids are not addictive.

In essence, the journal isn’t commenting on the merits of the letter — the problem is how it’s been used by others.

The same issue of the journal includes a letter by researchers based in Canada who analyzed how the 1980 letter had been cited, noting:

Journal: Here’s why we didn’t retract this duplicated paper

Here’s something we don’t see every day: A journal explains in an erratum notice why it chose not to retract a paper that contains data published elsewhere.

According to the Journal of Business and Psychology, the authors violated the journal’s transparency policy by failing to disclose that they’d used the same data in their 2014 in three others. However, the editors ultimately concluded the current paper was different enough from the other three to save it from being retracted.

Here’s the erratum: Continue reading Journal: Here’s why we didn’t retract this duplicated paper

When most faculty publish in predatory journals, does the school become “complicit?”

Derek Pyne

Predatory journals – which charge high fees and often offer little-to-no vetting of research quality – are a problem, and lately an easy target for authors eager to spoof the problems of the publishing system. Although many researchers try to steer clear, not all do – a recent paper showed that some top economists publish papers in potentially predatory journals. Now, a new paper in the Journal of Scholarly Publishing reports the problem may be even more widespread. Derek Pyne found that most of his colleagues at the School of Business and Economics at Thompson Rivers University in British Columbia, Canada have at least one paper in a predatory journal. We talked to Pyne about how his colleagues and administrators reacted to his findings – and how he believes they should address them.

Busted: Researcher used fake contact info for co-authors

In February, Lusine Abrahamyan, an assistant professor at the University of Toronto, was contacted by ResearchGate. Her name was listed on a 2016 paper in a heart journal, the site told her — was Abrahamyan indeed a co-author?

Um, no, she was not. In fact, before that moment, she didn’t know such a paper existed.

It turns out, Abrahamyan had supervised the thesis of the first author — who, she soon learned, had also published an identical paper in another heart journal. Both have since been retracted.

How did this happen?

International Cardiovascular Forum Journal editor Andrew Coats told us more about the actions of first author Joshua Chadwick Jayaraj: Continue reading Busted: Researcher used fake contact info for co-authors

“A Course In Deception:” Scientist’s novel takes on research misconduct

Jana Rieger

Jana Rieger is a researcher in Edmonton, Alberta. And now, she’s also a novelist. Her new book, “A Course in Deception,” draws on her experiences in science, and weaves a tale of how greed and pressures to publish can lead to even worse outcomes than the sort we write about at Retraction Watch. We interviewed Rieger about the novel.

Retraction Watch (RW): You tell the book from the point of a view of a fictional first-person narrator, a sleep researcher in Edmonton, Alberta, Canada. You, too, are a researcher in Edmonton. Is there any Jana Rieger in Mackenzie Smith? Continue reading “A Course In Deception:” Scientist’s novel takes on research misconduct
