The Economist takes a look at the Anil Potti misconduct case at Duke University — Potti, Joseph Nevins, and colleagues published reports saying that they could predict lung cancer progression based on gene expression levels determined using microarrays. Questions began to arise about the science as well as about some claims Potti made on various documents. This led to a number of papers being retracted, clinical trials being halted, and investigations being started. Potti resigned from his position at Duke.
