After “considerable intellectual agony,” journal retracts Wansink paper

Eduardo Franco

Ever since critics began raising concerns about high-profile food scientist Brian Wansink’s work, he’s had to issue a series of high-profile retractions — and now has his seventh (including one paper that was retracted twice, after the journal removed a revised version, along with 14 corrections). The latest notice — first reported by BuzzFeed —  is for a paper that was originally corrected by the journal Preventive Medicine earlier this month — and the correction notice was longer (1636 words) than the original, highly cited paper (1401 words). Following criticism by James Heathers about the highly cited study back in March 2017, the authors issued a series of changes, including explaining the children studied were preschoolers (3-5 years old), not preteens (8-11), as originally claimed. (They made that mistake once before, in another retracted paper.) But critics remained concerned. Yesterday, the journal retracted the paper. We spoke with editor Eduardo Franco of McGill University — who provided us with an advanced copy of an accompanying editorial, soon to be published — about the editorial processes behind the two notices, including the moment the journal knew the correction wouldn’t suffice.

Retraction Watch: You write that the initial decision to correct the paper came with “considerable intellectual agony.” Can you say why?

Florida investigation can’t ID culprit who falsified data in retracted PNAS paper

When the Proceedings of the National Academy of Sciences retracted a gene therapy paper in December, it declared that some of the data had been falsified and mentioned a research misconduct investigation. But the notice said nothing about who was responsible.

Via a public records request, Retraction Watch has obtained investigation documents from the University of Florida, which show the focus had been narrowed down to two of the paper’s three co-first authors. But the investigation committee didn’t assign blame to either one. According to their final report, dated Oct. 24, 2016:

there was not enough direct evidence to either implicate or exonerate either of these individuals.

Over the course of the formal investigation, which lasted from early August to late October 2016,  the committee was able to determine that data in the PNAS paper had been falsified. However, it said: Continue reading Florida investigation can’t ID culprit who falsified data in retracted PNAS paper

Chemistry journal retracts highly criticized paper

A chemistry journal has retracted a nanoparticle paper following heavy outcry from readers, who alleged the paper contained signs of obvious manipulation.

After the paper appeared in 2017, one critic lamented it contained “obviously fabricated” images, and asked the journal to retract it. Another suggested the presence of one image merited “an instant lifetime ban.”

The first comment about the paper appeared on PubPeer three months ago; earlier this month, the journal ACS Biomaterials Science & Engineering retracted the paper.

Here’s the notice:

Stanford prof plans to drop $10m suit against PNAS and critic

Mark Jacobson

A professor who is suing a journal publisher and critic for defamation has announced he plans to drop the case.

Yesterday, Stanford University professor Mark Jacobson announced on Twitter that he plans to “voluntarily dismiss the lawsuit” he filed last year in the District of Columbia, in which he alleged he was defamed when the Proceedings of the National Academy of Sciences published a paper critical of his research on the future of renewable energy.

Author: Journal’s unapproved edits distorted my ideas

Researcher Floribert Patrick Endong had been looking forward to seeing his paper in print. Several months after he submitted it to Gender Studies, the journal told him in March that it was online. But when he read it, Endong was disappointed to see some changes he had not approved, which he believed “deformed much of the initial text.”

It turns out, the journal “did not allow me to vet the changes before publication,” he explained. Continue reading Author: Journal’s unapproved edits distorted my ideas

“Major advance” in solar power retracted for reproducibility issues

The authors of a highly cited 2016 research letter on a way to improve the efficiency of solar panels have retracted their work following “concerns about the reproducibility.”

Given the potential importance of the data, it would be nice to know what exactly went wrong, and why. However, the retraction notice doesn’t provide many details, and doesn’t even specify if the authors did indeed fail to reproduce the data.

The letter, titled “Graded bandgap perovskite solar cells,” was published in Nature Materials by a group out of the University of California at Berkeley and the affiliated Lawrence Berkeley National Laboratory. The 2016 article has been cited 16 times, according to Clarivate Analytics’ Web of Science, earning it the ranking of “highly cited.”

Berkeley heralded the findings in a press release as a “major advance” in the field of solar energy:

Should a journal retract a paper the authors didn’t know contained bad data?

A medical journal has retracted a 2016 paper over a series of errors, prompting it to lose faith in the paper overall. The authors have objected to the decision, arguing the errors weren’t their fault and could be revised with a correction — rather than retracting what they consider “an important contribution” to an ongoing debate in medicine.

The paper explored the so-called weekend effect—that patients admitted to the emergency department on the weekend are more likely to die than those admitted on a weekday. Whether the weekend effect is real is not clear. Some studies have supported the phenomenon in certain areas of medicine, but others (including the now-retracted paper) have failed to find an effect.

First author Mohammed A. Mohammed, based at the University of Bradford in the UK, told Retraction Watch that the errors were introduced by one of the hospitals that provided them the data:

“The sampling had been compromised:” MD Anderson researchers retract cancer study

Erich Sturgis

Researchers from the University of Texas, MD Anderson Cancer Center have retracted a 2015 paper after they discovered their samples had been compromised.

Exactly how the samples were compromised, and how and when the researchers found out, remains unclear.

Originally published March 30, 2015, in Cancer, “Genome-wide association study identifies common genetic variants associated with salivary gland carcinoma and its subtypes” reported that at least three protein-coding gene variants were associated with rare salivary gland cancers. In the paper, the authors — all but one of whom are affiliated with MD Anderson — cautioned that they still needed to confirm the findings and figure out the mechanism by which the genes might increase the risk of cancer.

On Oct. 23, 2017, the researchers asked the journal to either correct or withdraw the paper. According to the retraction notice issued Jan. 9, the researchers had discovered: Continue reading “The sampling had been compromised:” MD Anderson researchers retract cancer study

Most board members of journal resign to protest new editor, layoffs

Detlev Ganten

Nearly all of the editorial board members of a 150-year-old journal about the molecular underpinnings of medicine and disease have resigned their posts, protesting changes by publisher SpringerNature that they say “jeopardized the future and scholarly legacy of the Journal.”

In a December 1 letter, led by the three former editors in chief of the Journal of Molecular MedicineDetlev Ganten, Gregg Semenza and Thomas Sommer — more than 70 then-editorial board members raised two objections: closing a small editorial office and laying off staff, and unilaterally appointing a new editor.

Regarding the decision to close the office at the Max Delbrück Center for Molecular Medicine (MDC) Berlin Buch, where it has been since 1995,  the editors and board members wrote: Continue reading Most board members of journal resign to protest new editor, layoffs

Caught Our Notice: Brian Wansink issues correction that’s longer than original paper

Title: Attractive names sustain increased vegetable intake in schools

What Caught Our Attention: One thing can be said for the corrections for Brian Wansink‘s papers — they aren’t short.  After James Heathers outlined some of his concerns about the highly cited study back in March, 2017, the journal has issued a correction, and it’s longer (1636 words) than the original, highly cited paper (1401 words). Some of the changes include explaining the children studied were preschoolers (3-5 years old), not preteens (8-11), as originally claimed. (It may be hard to imagine how the authors could make such a mistake, but they did it once before, in another retracted paper.) Even with all those words explaining the correction — we’re only including an excerpt of the entire notice below — some concerns still remain: Continue reading Caught Our Notice: Brian Wansink issues correction that’s longer than original paper
