This week, Kathleen tells us all about misconduct and fraud within science. What is scientific misconduct? Why would a scientist be motivated to commit fraud? And how is this type of crime caught and punished in academia? Then Natalie tells us a tragic story of a prominent researcher who just wouldn't listen to evidence against his theory on sudden infant death syndrome, and Erin tells us the scandalous tale about a stem cell scientist who was involved with the black market, money laundering, government ties, and some very questionable research practices.
