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.

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.

We discover the "you" inside your head - the part of your mind, sitting right behind your forehead that decides what you do every waking second of the day. We reconstruct a 150-year-old accident that caused a railroad worker named Phineas Gage to lose his sense of self; see children's reasoning powers gradually come on line; and scan Alan Alda's brain as he struggles to make decisions while feeling cheated.

When a veteran Washington D.C. police detective (Wesley Snipes) is called in to investigate the murder of a woman at the White House, he uncovers a complex and deadly web of corruption and deceit. With the help of a reluctant Secret Service agent (Diane Lane), he struggles to stop the killer from carrying out a plot that will affect the entire country. Starring action superstar Snipes (the "Blade" movies, "The Art of War"), Oscar-nominee Diane Lane ("The Perfect Storm," "My Dog Skip"), five-time Emmy-winner Alan Alda ("Mad City," TV's "M*A*S*H"), two-time Emmy-winner Dennis Miller (TV's "Dennis Miller Live," "Bordello of Blood"), Ronny Cox ("American Outlaws," TV's "The Agency"), Tate Donovan ("Swordfish," "Hercules") and Daniel Benzali (TV's "The Agency," TV's "Murder One"). Produced by Academy Award-winner Arnold Kopelson ("Se7en," "The Fugitive").

In spite of the risks, people are lining up to solve their weight problems in the operating room. And if the latest device -- an implantable stomach "pacer" -- works out, millions more will be taking the surgical way out. We follow two patients as they go through the life-transforming experience of gastric bypass surgery, causing dramatic weight loss. Both patients achieve major life goals, from the simple act of shopping in a regular - not plus-size - clothing store, to the substantial reduction of health risks like heart attack and diabetes. Alan Alda observes Amy's surgery at a Boston hospital, and visits Rodney as he recovers the day after his operation. Gastric bypass, in which a small, one-ounce, stomach "pouch" is created to replace the natural stomach, is the most common stomach surgery in the US, with 100,000 procedures performed a year - ten times the rate ten years ago. Nationally, 75% of those patients will achieve substantial permanent weight loss, although some will be able to "behaviorally"
