More notices appear for embattled Cornell food researcher

Journals have posted two corrections alongside papers by Brian Wansink, a food researcher whose work has lately come under fire.

One of the corrected papers was among the initial batch that raised eyebrows last year; after Wansink praised the productivity of one of his researchers, critics suggested four papers contained critical flaws. The questions about his work soon extended to other papers, one of which was retracted in April. That month, an internal review by Cornell University announced that Wansink made numerous mistakes, but did not commit misconduct. Wansink has pledged to reanalyze multiple papers.

One paper that was among those initially criticized has received a formal correction notice from the Journal of Product & Brand Management. The notice, which appears behind a paywall, has drawn fire from a regular critic of Wansink’s work, Jordan Anaya, who argues “this correction actually needs a correction, actually several.”

Here’s the notice for “Peak-end pizza: prices delay evaluations of quality:”

“The correct values are impossible to establish:” Embattled nutrition researcher adds long fix to 2005 paper

A Cornell food researcher who has pledged to re-analyze his papers following heavy criticism of his work has issued a major correction to a 2005 paper.

The correction tweaks two tables, a figure, and the description of the methodology — and notes in two instances the correct findings are unknown, since the original data are unavailable. Andrew Gelman, a statistician at Columbia University and critic of Brian Wansink’s work, has dubbed the notice the “best correction ever.”

The paper, about whether changing the name of food influences its taste, was not among the batch of papers initially flagged by critics last year. Since then, researchers have raised additional questions about Wansink’s work; one of his papers was retracted in April. That same month, an internal review by Cornell University concluded that Wansink made numerous mistakes, but did not commit misconduct.

When we contacted Wansink about the correction, we received this statement from the Cornell Food and Brand Lab, which Wansink directs:

Journal flags paper about GMO foods over concerns about figures

A journal has flagged a paper by a researcher who has questioned the safety of genetically modified organisms, after receiving concerns that there were issues with some images.

In the 2006 paper, researchers led by Federico Infascelli, an animal nutrition researcher at the University of Naples, tested the blood of rabbits fed genetically modified soybeans. Starting in November 2015, however, the journal animal fielded concerns that gels appeared manipulated, and a figure legend differed from that in a thesis associated with the research.

This isn’t the first notice issued for Infascelli’s controversial work, which has been under scrutiny in recent years, including by Italian senator and biologist Elena Cattaneo. Last year, he was formally reprimanded by the University of Naples for including manipulated data in three papers.

Although the University of Naples concluded the image manipulations were “not a breach of scientific integrity,” the journal has issued a lengthy expression of concern about the paper:

Idea theft: Two food chemistry papers retracted for using someone’s ideas

A researcher has retracted two papers after her former supervisor complained she had used his ideas and methodology.

In addition, some of the work was apparently covered by a copyright agreement.

Both papers were co-authored by the same three people. The idea theft came to light after one of the co-authors received a complaint from her former supervisor, prompting her to contact the publisher to resolve the issue.

Wendy Hurp, executive publisher of Food Science at Elsevier, which publishes the two journals, provided some additional background on what happened: Continue reading Idea theft: Two food chemistry papers retracted for using someone’s ideas

Nightmare scenario: Text stolen from manuscript during review

A food science journal has retracted a paper over “a breach of reviewer confidentiality,” after editors learned it contained text from an unpublished manuscript — which one of the authors appears to have reviewed for another journal.

The publisher and editors-in-chief of the Journal of Food Process Engineering became aware of the breach when the author of the unpublished manuscript lodged a complaint that his paper, under review at another journal, had been plagiarized by the now retracted paper.

We’re hazy on a few details in this case. Although the journal editor told us the “main author” of the retracted paper reviewed the original manuscript for another journal, the corresponding author of the retracted paper said he was not to blame. (More on that below.)

When looking into the matter, the publisher found that one of the co-authors of the published paper had acted as a reviewer of the unpublished manuscript. Alexandra Cury, an associate editor at Wiley, explained: Continue reading Nightmare scenario: Text stolen from manuscript during review

Tomato study didn’t get co-author okays, includes unreliable data

scientia-horticulturaeA journal has retracted a paper examining the traits of drought-resistant tomatoes after an investigation at the first author’s institution in Italy found a number of problems.

For starters, the first author — Maria Riccardi of the National Research Council of Italy-Institute for Agricultural and Forest Systems in the Mediterranean (CNR-ISAFOM) in Ercolano, Naples, Italy — apparently submitted the paper without consulting the study’s four other listed co-authors. What’s more, according to the retraction notice in Scientia Horticulturae, the paper’s description of the experiment “does not reflect the real conditions under which the data was collected,” rendering the findings invalid.  

Riccardo d’Andria, CNR-ISAFOM’s former director who conducted an investigation into the case, said Continue reading Tomato study didn’t get co-author okays, includes unreliable data

Retraction notice for GMO paper updated to include fraud

fns2015012717103119Earlier this year, a nutrition journal retracted an article about the potential dangers of eating food containing genetically modified organisms (GMOs), noting the paper contained a duplicated image.

At the time, news outlets in Italy were reporting accusations that the last author, Federico Infascelli, an animal nutrition researcher at the University of Naples, had falsified some of his research.

Food and Nutrition Sciences has now updated its initial notice, saying the paper was pulled for data fabrication. In addition, Infascelli is no longer listed on its editorial board – he is included on an archived link to the editorial board from March 2016, but not on the current list of members.

Here is the updated version of the retraction notice for “Gamma-Glutamyl Transferase Activity in Kids Born from Goats Fed Genetically Modified Soybean:” Continue reading Retraction notice for GMO paper updated to include fraud

USDA finds “evidence of manipulation” in vaccine study

VaccineA journal is retracting a paper by scientists at the U.S. Department of Agriculture about a vaccine to protect fish from a deadly bacterial infection, after an investigation found evidence of data manipulation. 

The retraction notice — which appears in the journal Vaccine — cites an investigation by the USDA. It also notes that the authors — who are no longer with the USDA — have not agreed to the retraction.

Here’s the retraction notice, issued on August 20: Continue reading USDA finds “evidence of manipulation” in vaccine study

You’ve been dupe’d: Nice data — let’s see them again

As we’ve said before, with hundreds of retractions per year, there are simply too many for us to cover individually.

So from time to time we’ll compile a list of retractions that appeared relatively straightforward, just for record-keeping purposes.

Often, these seemingly straightforward retractions involve duplications, in which authors — accidentally or on purpose — republish their own work elsewhere.

Sometimes journals and authors blame this event on “poor communication,” our first example notes:

Did an author retract a paper at company’s behest? Retraction notice says yes, author now says no

Screen Shot 2016-06-24 at 15.59.31

The author of a paper whose retraction notice says it was pulled at the behest of a company now says that wasn’t the case.

It’s a bit difficult to get this story straight: Although the retraction notice says a company complained the 2006 paper was “giving business inputs to their competitors,” the corresponding author told us no one asked him to retract the paper. Instead, he said, he was concerned about the inclusion of plant materials that belong to a previous employer, and did a “poor job” of explaining the reason for retraction. But since the results of the paper remain valid, Santosh Rajput — now a plant breeder at Dryland Genetics LLC in Ames, Iowa — told us he regrets asking to retract it:
