Fat and Happy? (Episode #1110)
KQED World: Thu, Nov 29, 2012 -- 6:00 AM
This episode discusses America's latest epidemic, obesity. While 20% of adults are clinically obese, now 25% of children are too, and the proportion is steadily increasing. What shape will Americans be in within a decade or so? The program looks at research on fad diets; on the real relationships between activity and weight; on how well-meaning mothers teach their kids to overeat; on how obese research subjects bend the truth about what they eat; and on the movement of Native Americans, suffering from widespread obesity-related diabetes, to get back to traditional wild food diets.

Future Car (Episode #1403)
KQED World: Thu, Nov 22, 2012 -- 6:00 AM
Alan Alda visits the research labs and testing tracks of the Big Three auto makers to find out what people will be driving 10-20 years from now. Fuel efficiency and alternative fuels are the future, and Alda test-drives a gasoline-electric hybrid that's already on the road, as well as several hydrogen-fueled cars still in development. The search for a quiet, fast, safe, exciting and non-polluting fuel- cell car takes Alda from Germany to California to Iceland, which is attempting to become the first nation to entirely replace imported petroleum with domestically produced hydrogen.

Don't Forget (Episode #1402)
KQED World: Thu, Nov 15, 2012 -- 6:00 AM
Alan Alda investigates how people create memories - and how as they age, memories become slippery and elusive, sometimes vanishing forever. He visits two men who live entirely in the present or the distant past, unable to recall events that happened even a few minutes ago. Viewers peer inside Alda's own brain and find out what's at work as he memorizes names and faces. Alda discovers how ice water can boost memory (no, not drinking it) and how easy it is to have a false memory implanted. He also meets a volunteer in an experimental treatment for Alzheimer's disease, gets the latest on the search for an Alzheimer's vaccine and joins a group of baby boomers who are learning how to keep their brains young and their memories intact.

Losing It (Episode #1401)
KQED World: Thu, Nov 8, 2012 -- 6:00 AM
This sequel to a popular Frontiers episode, "Fat and Happy?," tackles the basic problem that confronts those who are overweight - how to lose weight and keep it off over the long term. In a Frontiers-sponsored experiment, the cameras follow a dozen subjects for several months as they adopt different strategies for weight loss, ranging from online diet systems to gastric bypass surgery. The program also looks at research that attempts to get to the bottom of the body's complex weight-regulation system, and to explain, among other things, why dieting is so difficult.
