Another stem cell paper has been retracted from Nature, this one a highly cited 2008 study that had already been the subject of what the journal’s news section called a “furore” in 2010.
According to that 2010 news story:
The researchers behind the original work1, led by Thomas Skutella of the University of Tübingen, reported using cells from adult human testes to create pluripotent stem cells with similar properties to embryonic stem cells.
But a 2010 Brief Communication Arising called those findings into question. And now, the authors have retracted the paper. Here’s the notice for “Generation of pluripotent stem cells from adult human testis:” Read the rest of this entry »
A former postdoc at MD Anderson Cancer Center faked the results of a mouse study of a Novartis compound designed to fight brain tumors, according to the Office of Research Integrity (ORI).
Jun Fu “admitted to knowingly and intentionally falsifying Figure 8a” in “Novel HSP90 Inhibitor NVP-HSP990 Targets Cell-Cycle Regulators to Ablate Olig2-Positive Glioma Tumor–Initiating Cells,” a paper published in Cancer Research on May 15, 2013: Read the rest of this entry »
A stumble in data preparation earned a retraction for a paper on delirium tremens, a life-threatening side effect of alcohol withdrawal that spans a wide range of symptoms, including hallucinations and seizures.
Though the initial retraction notice was extremely unhelpful, the author stepped in to give us a better picture of the errors that led to the paper’s demise.
Here’s the notice from Alcohol and Alcoholism about “Biochemical Predictors of Delirium Tremens in Patients in Alcohol Withdrawal”:
A group of researchers at Stanford and elsewhere is retracting a 2013 paper that another scientist told Nature was “one of the biggest things to happen in the narcolepsy field for some time.”
Fred Walumbwa, the leadership researcher at Florida International University who has retracted six papers for what appear to be problematic data, now has an impressive mega-correction in the form of an “addendum.”
The paper, “Relationships between Authentic Leadership, Moral Courage, and Ethical and Pro-Social Behaviors,” was published in Business Ethics Quarterly in October 2011, by Walumbwa and two colleagues, Sean Hannah and Bruce Avolio.
Here’s the abstract for the paper, which has been cited 18 times, according to Thomson Scientific’s Web of Knowledge:
