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The article, titled “Dextran Sulfate Sodium Inhibits Alanine Synthesis in Caco-2 Cells,” appeared in 2011 and was retracted in February 2012, although it just came to our attention.
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.
A frequent co-author of Ulrich Lichtenthaler — the management professor who has retracted at least eight papers — has now withdrawn one of his own from Research Policy.
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.
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 Therefore, we have withdrawn these 4 isolates from GenBank and subsequently retract this letter.
A rising star at MIT has retracted a paper after an investigation found that her former postdoc had “falsified or fabricated figures.”
Alice Ting, winner of an NIH Directors Pioneer Award and named one of Technology Review’s “Innovators Under 35,” published the paper, “Imaging Activity-Dependent Regulation of Neurexin-Neuroligin Interactions Using trans-Synaptic Enzymatic Biotinylation,” in Cell in 2010 along with Amar Thyagarajan.
Today brings two journal editorials about misconduct and retractions. They take, if we may, a bit of an optimistic and perhaps even blindered approach.
