After typing up 96 citations, researchers from the National Institute for Digestive Diseases, I.R.C.C.S. “S. de Bellis,” in Bari, Italy, apparently ran out of steam for the last five, earning themselves a retraction for plagiarism in a literature review of the effects of probiotics on intestinal cancer.
Guangwen Tang, a rice researcher at Tufts University, landed in hot water in 2012 after her team was accused of feeding Chinese children genetically modified Golden Rice without having obtained informed consent from the parents.
Now, she’s suing both Tufts and the American Journal of Clinical Nutrition, which reportedly is retracting a paper, “ß-carotene in Golden Rice is as good as p-carotene in oil at providing vitamin A to children,” based on the federally funded research, claiming that the retraction would constitute defamation. (That retraction hasn’t happened yet.)
This isn’t the first time we’ve heard the retraction = defamation line. Readers might remember Ariel Fernandez, who threatened to sue us for writing about an expression of concern. Maybe a course on the Streisand Effect should be mandatory for PhD students?

Researchers at Qingdao University have fully retracted a paper originally published in Molecular Medicine Reports with a clear, detailed outline of what went wrong and how they discovered the error.
Here’s the notice for “Generation of induced pluripotent stem cells using skin fibroblasts from patients with myocardial infarction under feeder-free conditions:”
A Boston doctor indicted on charges of Medicare fraud in 2007 has had a paper relating to the case retracted this month.
Abdul Razzaque Ahmed was considered something of a miracle worker by his patients, treating two rare and disfiguring skin conditions called pemphigoid and pemphigus vulgaris. He used more powerful medicines than the typical course of treatment, including a drug normally used to treat cancer.
The initial indictment stated that Ahmed mixed blood samples to falsely show a “dual diagnosis” of both diseases, and prove to Medicare that they required the more rigorous (and expensive) treatment. It also alleged that he profited massively from the government pay-outs. He was convicted of obstruction in 2007; the other charges were dropped when he agreed to forfeit assets worth $2.9 million.
Now, a 2001 paper by Ahmed, which claimed fifteen patients had a dual diagnosis, has been retracted because the samples were all mixed. Here is the retraction notice from Clinical Immunology: Read the rest of this entry »
