This is episode five of Swimming with Shadows: A Radiolab Week of Sharks.

Today, the strange, squirmy magic behind how sharks make more sharks. Drills. Drama. Death. Even a coliseum of baby sharks duking it out inside mom’s womb. And a man on a small island in the Mediterranean trying, against all odds, to give baby sharks a chance in a little plastic aquarium in his living room. Can a human raise a shark? And if so, what good is that for sharks? And for us? Doo doo doo doo doo doo.

This is episode four of Swimming with Shadows: A Radiolab Week of Sharks.

Alison Kock was working at a car wash in Cape Town when she made a discovery that completely changed the course of her life. Inside a customer’s trunk, she found photographs of white sharks flying so high above the water they looked like airplanes. She followed those photographs to False Bay, “the Great White Capital of the World.” These sharks, in this place, are the apex of apex predators. Or they were. Until they mysteriously began to disappear.

Special thanks to Kathryn Ayres.

Jilted lovers and disrupted duck hunts provide a very odd look into the soul of the US Constitution.

What does a betrayed lover’s revenge have to do with an international chemical weapons treaty? More than you’d think. From poison and duck hunts to our feuding fathers, we step into a very odd tug of war between local and federal law.

When Carol Anne Bond found out her husband had impregnated her best friend, she took revenge. Carol's particular flavor of revenge led to a US Supreme Court case that puts into question a part of the US treaty power.

Producer Kelsey Padgett drags Jad and Robert into Carol's poisonous web, which starts them on a journey from the birth of the US Constitution, to a duck hunt in 1918, and back to the present day. It’s all about an ongoing argument that might actually be the very heart and soul of our system of government.
