Giving Thanks on Skid Row, the Science of Addiction, and Dick Cavett

We start by talking to the managing director of the Midnight Mission on Skid Row, where celebrities and regular citizens alike will be serving up Thanksgiving meals to the homeless tomorrow. Then, a look at some new science on how addiction works, including a recent study on alcoholism from the Centers for Disease Control. Next up, the EPA is proposing new, tighter rules on ozone emissions: What does it mean for Southern California? We hear from legendary talk show host Dick Cavett about his new memoir, and, finally, in our weekly web roundup we discuss how the situation in Ferguson, Mo., is playing out in social media.
