A group of nutrition researchers at the University of California, Davis has retracted their paper in the International Journal of Molecular Sciences for what they describe as a botched experiment involving mixed-up cultures.
The article, titled “Dextran Sulfate Sodium Inhibits Alanine Synthesis in Caco-2 Cells,” appeared in 2011 and was retracted in February 2012, although it just came to our attention.
According to the abstract:

Hiroaki Matsubara, a leading Japanese cardiology researcher who has had three papers retracted and another five subject to expressions of concern, has resigned from Kyoto Prefectural University, according to local media.
Mainichi Shimbun reports — according to our roughest of (Google) translations — that Kyoto Prefectural University accepted Matsubara’s resignation following an investigation. That investigation — which the university had told us about last year — revealed serious problems with 27 studies.
As we noted last March: Continue reading After three retractions, five expressions of concern, cardiologist Matsubara resigns post
Sanjeeb K. Sahoo, of the Institute of Life Sciences in Bhubaneswar, India, has had four papers retracted from Acta Biomaterialia for what the journal is calling “highly unethical practices.”
All four notices say the same thing: Continue reading “Highly unethical practices” force four retractions for nanotech researcher
Retraction Watch readers may recall the case of William Hamman, the United Airlines pilot who claimed to be a cardiologist until the Associated Press uncovered him in late 2010. Hamman had published at least six papers, and since the revelations has had one retraction and one erratum, by our count.
Now comes another retraction, in the Journal of Patient Safety. Here’s the (paywalled) notice, signed by journal editor Charles Denham: Continue reading Paper by fake cardiologist retracted
As a first-year medical student at the University of California, San Diego, Jessica Tang already has an impressive CV. Her name has appeared on ten papers in the medical literature, including three in the Journal of Neurosurgery: Spine. On one of these she was the sole author.
Except that one doesn’t exist anymore. But the reason for the retraction does not appear to involve shoddy work by the researcher. Rather, Tang failed to appreciate the politics of the lab in which she worked — and it cost her.

Plagiarism and duplication might involve the same act — the misuse of text and/or data — but they are different species. Take it from Eldon Smith, who as editor of the Canadian Journal of Cardiology defined the two acts of misconduct for his readers:
Plagiarism is the appropriation of another person’s ideas, processes, results or words without giving appropriate credit (1). One usually thinks of plagiarism in science as publishing phrases, sentences or passages (without attribution) that were previously published by someone else. …
If an author publishes the same article twice, he or she is guilty not only of the misconduct of duplicate publication, but also of plagiarism; this time, the author has plagiarized himself or herself. Unfortunately, such blatant misconduct is not rare. … It is difficult to understand how this can be interpreted as an honest error.
Perhaps the editors of the International Journal of Cardiology might want to take a look at Smith’s editorial. Continue reading Retraction Watch, Noah Webster style, cardiology edition
In late December, we reported on the retraction of a 2010 research letter in Emerging Infectious Diseases looking at the genetics of swine flu.
The notice in the journal, a CDC publication, indicated that the conclusions were in error, although it didn’t really say much more:
To the Editor: We would like to retract the letter entitled “Triple Reassortant Swine Influenza A (H3N2) Virus in Waterfowl,” which was published the April 2010 issue of Emerging Infectious Diseases (1). The nucleoprotein gene sequences from the viruses reported in that letter are very closely related to those from the earliest detected triple reassortant swine influenza viruses [CY095676 A/sw/Texas/4199–2/1998(H3N2)]. Although these viruses could have acquired a swine-origin segment, the branch lengths are quite short for 9 years of evolution. Therefore, we have withdrawn these 4 isolates from GenBank and subsequently retract this letter.
As it happens, there was more to the story.
The authors of a study published last year looking at the effects of cell phone exposure on mice in utero have corrected a figure after it was questioned. New experiments, they write, confirm the original conclusions they drew from the figure.
Here’s the corrected figure from the paper in Scientific Reports, published by Nature Publishing Group: Continue reading Paper linking cell phones during pregnancy to behavior problems in mice corrected
The journal Cyberpsychology, Behavior, and Social Networking is retracting a paper about Facebook.
“Bridging the Gap on Facebook: Assessing Intergroup Contact and Its Effects for Intergroup Relations,” is by Sandy Schumann of the Free University of Brussels. The notice says only:
This article has been officially retracted from the Journal.
We asked journal editor Brenda K. Wiederhold for more information about the retraction, and she responded: Continue reading Facebook study retracted after authors request substantial changes
Today brings two journal editorials about misconduct and retractions. They take, if we may, a bit of an optimistic and perhaps even blindered approach.
In an editorial titled “Scientific misconduct occurs, but is rare,” Boston University’s Richard Primack, editor of Biological Conservation, highlights a Corrigendum of a paper by Jesus Angel Lemus, the veterinary researcher who has retracted seven papers: Continue reading Not in my journal: Two editors take stock of misconduct in their fields — and don’t find much
