Our guest, Barbara O’Brien, explains why we don’t know much about conviction error outside of murder cases, making error rates for the vast majority of crimes: misdemeanors, sexual assaults, armed robbery, etc. a “dark ocean”.

Steve and Corey talk to Jason about a fundamental question of neuroscience: Do humans grow new neurons as adults? The dogma that humans do not, gave way to the dogma that they do, which is now being questioned. Adult neurogenesis has been associated with learning, better cognitive function and resistance to depression. Jason suggests that a simple error of treating young mice as models for adult h...

Steve and Corey talk to Tim Searchinger about the unintended consequences of biofuels policies. Searchinger argues that these policies do not consider the opportunity costs of using plants for fuel rather than food.
