Clear+Vivid with Alan Alda

Most creatures play– even octopuses, pigs, crows and bees. But play is much more than fun and games. Play teaches life skills and empathy – even morality. And it may help shape evolution. Want to play?

An astrophysicist brings the universe down to earth. In brief captivating videos she tells the stories of how everything our world is made of – including ourselves – was created in cataclysmic explosions and collisions far out in space.

When we experience things that seem beyond explanation, are they evidence of the supernatural? Or instead, a quirk of our brains? A skeptical but open-minded psychologist has some entertaining answers. 

Sharing her experiences of three space missions – including 159 days as the only woman on the 6-person crew of the International Space Station – Cady Coleman also shares lessons about getting along:valuable insights for the rest of us down here on earth.

Alan and the author of a new book called Supercommunicators share their thoughts on what makes a great conversation.  The result? A great conversation!

The world of the very small is very different from the one we are familiar with. (Gold for instance turns red.) Chad Mirkin and Robert Langer’s skills in crafting this bizarre micro-world into medical breakthroughs earned them the 2024 Kavli Prize in nanotechnology.

He is searching space for planets that are something like ours. She is searching brains to discover how we recognize things. They are both 2024 Kavli laureates – Charbonneau awarded the prize for astrophysics, Tsao for neuroscience.

That was the question two determined astronomers set out to answer. A frustrating five-year search revealed that Pluto, long thought to be a small, lonely planet on the outer fringes of the solar system, is in fact part of a huge ring of debris left over from the solar system’s birth.

Between them these two neuroscientists changed the way we think of our brains. Their insights are now opening new ways to tackle the problems our brains face as they age, including neurodegenerative diseases such as Alzheimer’s. 

Once sworn enemies in TV appearances and on social media, Fred Guttenberg and Joe Walsh got together privately and realized there is much that unites them. They are now on a tour of college campuses hoping to share their success in bridge-building with others divided by hate.
