Cars That Think (Episode #1502)

KQED World: Thu, Dec 27, 2012 -- 9:30 AM

The fully automatic car may be down the road a ways, but cars that do your thinking for you are just around the corner - they watch out for hazards, they listen to you, they read your lips, they even know when you're distracted.

Surgical Slimmers (Episode #1501)

KQED World: Thu, Dec 27, 2012 -- 9:00 AM

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.

Hot Times In Alaska (Episode #1404)

KQED World: Thu, Dec 20, 2012 -- 6:00 AM

Alaska is warming up. It's now a few degrees warmer than it was a century and a half ago, and the trend seems to be accelerating. Already the landscape is changing dramatically - permafrost is thawing, glaciers are melting, forests are succumbing to drought and insect attack. Alan Alda meets Alaskan scientists who are working to find out if these are the first signs of global warming and what the future may hold.

Coming to America (Episode #1406)

KQED World: Thu, Dec 13, 2012 -- 6:00 AM

Who were the first Americans, and when did they arrive? Did they get here by land or sea? Did a single group populate the continent, or did many? Experts used to agree that the first Americans walked across the Bering land bridge from Asia about 12,000 years ago, then found their way south, eventually colonizing all of North and South America. But exciting recent finds at sites on both continents have triggered new theories. Alan Alda tries to find out who's saying what, and why.

The Dark Side of the Universe (Episode #1405)

KQED World: Thu, Dec 6, 2012 -- 6:00 AM

Alan Alda joins some of the world's leading astronomers as they wrestle with the startling implications of their latest discoveries: that everything we can see, from the world around us to the most distant galaxies, is only a tiny fraction of the entire cosmos. Most of what's out there is dark - either dark matter or dark energy. And our universe is perhaps only one in an infinity of universes.
