Out Of The Mental Illness Box
When treating mental illness, you know the drill. Take your meds. Call me in the morning. Let's check in on how you feel in a few months. Repeat.
But maybe there’s something else you can add to that toolkit.
We talk with a psychiatrist who prescribes exercise as medicine, a woman who treats her anxiety with horror films, and the scientists examining how depression can be treated with psychedelics.
Need to talk? Contact the National Alliance for Mental Illness at 1-800-950-NAMI (6264).

Loving Bees
Bees stir each one of our senses — the zen-like hum, the sweet honey, the waxy smell of wildflowers mixed with hard work, the vibrant orange and black bodies attached to window-paned wings.
If they land on us, and we are calm, say beekeepers, it will be a gentle touch; they will sting only to save their lives.
Bees are endangered, but all over the world, people are stepping up to save them — in backyards, science labs, and the abandoned lots of urban Detroit. We explore the art to building a relationship with bees, and the science of how they thrive and what we might do to preserve them for future generations.

Mysteries of Migration
If you had to travel 500 miles across country, on foot, with no map, no GPS, without talking to anyone — to a destination you've never seen, could you do it? It sounds impossible, but millions of creatures spend their lives on the move, migrating from one part of the Earth to another with navigation skills we can only dream of. How do they do it — and what can we learn from them?

Jazz Migrations
Music crosses boundaries between traditional and modern, local and global, personal and political. Take jazz — a musical form born out of forced migration and enslavement. We typically think it originated in New Orleans and then spread around the world. But today, we examine an alternate history of jazz — one that starts in Africa, then crisscrosses the planet, following the movements of people and empires -- from colonial powers to grassroots revolutionaries to contemporary artists throughout the diaspora.
This history of jazz is like the music itself: fluid and improvisatory.
In this hour, produced in partnership with the Consortium of Humanities Centers and Institutes (CHCI) — a global consortium of 270 humanities centers and institutes — we hear how both African and African-American music have shaped the sound of the world today.

More Than Just a Game
We play them to pass the time at family functions, or to relax after a long day of work or school. But board games say so much more than we think — about our relationships, our politics, our histories. We learn the storied history of Mahjong, play a few classic games with some modern twists, and consider the mental brutality that is competitive chess.
