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? Original Air Date: July 25, 2020 Guests:  Moses Augustino Kumburu — David Wilcove — Stan Temple — David Barrie — Sonia Shah Interviews In This Hour:  The Serengeti's Great Migration, Up Close — Why Do Animals Migrate? — Sandhill Cranes Make The Long Journey South — The Greatest Navigators on the Planet — The High Costs — And Potential Gains — Of Migration, Both Animal And Human

Mysteries of Migration

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.   Original Air Date: July 04, 2020 Guests:  Meklit Hadero — Valmont Layne — Gwen Ansell — Ron Radano Interviews In This Hour:  How Meklit Hadero Reimagined Ethiopian Jazz — So You Say You Want A Revolution — Reclaiming the Hidden History of South African Jazz — 'We Are All African When We Listen' Further Reading: CHCI Ideas from Africa Hub

Jazz Migrations

The women of Afghanistan are elected officials, school teachers, actors, TV contest winners, ancient rug weavers, and whisperers of forbidden poetry. The Taliban are starting to put down their thumb. But these women want you to know they are more than the timid victim under a burqa. Original Air Date: October 02, 2021 Guests:  Humaira Ghilzai — Eliza Griswold — Anna Badkhen — Rafia Zakaria Interviews In This Hour:  What's the future of culture in Afghanistan? — For Afghan weavers, the world is a carpet — Generations of Afghan women sharing the landay — How Afghanistan became America's 'first feminist war'

What Afghan Women Want You to Know

We’ve all been changed by the experience of living through a pandemic. We figured out how to sanitize groceries, mute ourselves on Zoom and keep from killing our roommates. But we’re also tackling bigger, existential questions — how can we, individually and collectively, find meaning in the experience of this pandemic? Original Air Date: May 23, 2020 Guests:  David Kessler — Tyrone Muhammad — Nikki Giovanni — John Kaag — Alice Kaplan Interviews In This Hour:  Grief Is A Natural Response To The Pandemic. Here’s Why You Should Let Yourself Feel It. — 'You Smell Death': Being A Mortician In A Community Ravaged By COVID-19 — Nikki Giovanni Reads a Poem of Remembrance — Does Philosophy Still Matter In The Age Of Coronavirus? — Why Camus' 'The Stranger' Is Still a Dangerous Novel

Finding Meaning in Desperate Times

Using a complex network of chemical signals, trees talk to each other and form alliances with fellow trees, even other species. In fact, whole forests exist as a kind of superorganism. And some trees are incredibly old. Did you know a single bristlecone pine can live up to 6,000 years? And the root mass of aspens might live 100,000 years? We explore the science and history of trees and talk with Richard Powers about his epic novel "The Overstory." Original Air Date: April 28, 2018 Guests:  Mark Hirsch — Richard Powers — Suzanne Simard — Amos Clifford — Daegan Miller Interviews In This Hour:  A Year In The Life Of A Tree — Listening to the Mother Trees — Richard Powers on Writing the Inner Life of Trees — Bathing in the Beauty of the Trees — General Sherman, Karl Marx, and Other Aliases of Earth's Largest Tree

The Secret Language of Trees

For all the commentary, the sorrow and rage, all the second-guessing about everything that followed, it’s still hard to fathom what happened on 9/11. Photographer James Nachtwey was in New York that day, and he took some of the iconic photos of the Twin Towers as they crumbled. "I’ve actually never gotten over it," he says. On the twentieth anniversary of 9/11, Nachtwey reflects on his life as a war photographer, and we consider the deep history of war itself. We also examine a very difficult question: Is war ever worth it? Original Air Date: September 11, 2021 Guests:  James Nachtwey — David Shields — Leymah Gbowee — Margaret MacMillan Interviews In This Hour:  Remembering 9/11 Through The Lens Of A Photojournalist — War is Beautiful? — Humans Have Gotten Nicer and Better at Making War — Is War Inevitable?

Is War Ever Worth It?

Before the time of commercial flights and road trips, we traveled to far off places without taking a single step. All you had to do was open a book. From Africa to England, to a kamikaze cockpit, and to realms of fantasy. Books aren’t just books. They’re passports to anywhere. Original Air Date: March 14, 2020 Guests: Philip Pullman — Ruth Ozeki — Robert Macfarlane — Petina Gappah Interviews In This Hour: Philip Pullman on 'The Pocket Atlas of the World' — 'His Dark Materials' Author Philip Pullman On The Consciousness Of All Things — A Diary Becomes A Time Capsule — Ruth Ozeki on 'Kamikaze Diaries' — Petina Gappah on 'Persuasion' — The Empire Writes Back: Author Discusses Explorer David Livingstone's Complicated Legacy — Robert Macfarlane on 'The Living Mountain'

Traveling By Book

Not everyone has a nice, big yard to stretch out in while sheltering in place from COVID-19. But maybe you don't need one. People are using virtual spaces to live out the real experiences they miss — like coffee shops, road trips, even building your own house on a deserted island, or Walden Pond. In a world where we're mostly confined to our homes and Zoom screens, does the line between virtual and real-life space mean much anymore? Original Air Date: May 16, 2020 Guests: Mark Riechers — Tracy Fullerton — Simon Parkin — Jane McGonigal — Donald D. Hoffman — Suzanne O’Sullivan Interviews In This Hour: There's No Pandemic In Animal Crossing — I Went To The Woods To Level Up Deliberately — The Most Boring Video Game Ever Made — Want to be Happier? Turn Everyday Tasks Into a Game — How We Fool Ourselves With The Concept of 'Reality' Further Reading: NYAS: Reality Is Not As It Seems

Our Virtual Reality

Over the past decade, plant scientists have quietly transformed the way we think of trees, forests and plants. They discovered that trees communicate through vast underground networks, that plants learn and remember. If plants are intelligent beings, how should we relate to them? Do they have a place in our moral universe? Should they have rights? Human identity cannot be separated from our nonhuman kin. From forest ecology to the human microbiome, emerging research suggests that being human is a complicated journey made possible only by the good graces of our many companions. In partnership with the Center for Humans and Nature and with support from the Kalliopeia Foundation, To The Best Of Our Knowledge is exploring this theme of "kinship" in a special radio series. Original Air Date: December 19, 2020 Guests: Robin Wall Kimmerer — Matt Hall — Monica Gagliano — Brooke Hecht Interviews In This Hour: We've Forgotten How To Listen To Plants — We Share This World With Plants. What Do We Owe Them? — Guided by Plant Voices — The Botanical Medicine Cabinet

Plants As Persons

One of the toughest things about trying to understand climate change – arguably the most important story of our time - is wrapping our minds around it. To even imagine something so enormous, so life-changing, we need a story. Some characters, a metaphor, and even some lessons learned. For that, we turn to the novelists and journalists telling the story of climate change – as we – and our children – live it. Original Air Date: August 14, 2021 Guests: Alice Bell — Lydia Millet — Lidia Yuknavitch — John Lanchester Interviews In This Hour: The Climate Change Stories We Need To Hear — The Climate Crisis Gets Biblical — Lidia Yuknavitch’s Dream World: How Dreams Shaped Her Dazzling Speculative Novel — A Climate Dystopia Of Cold, Concrete, Wind and a Wall

Writing the Climate Change Story

We all miss touching things — groceries, door knobs, hands, faces. And most of all, skin. The living tissue that simultaneously protects us from the world, and lets us feel it. In this episode, the politics, biology, and inner life of your skin. Original Air Date: April 18, 2020 Guests: Angelo Bautista — Tiffany Field — Alissa Waters — Nina Jablonski Interviews In This Hour: My Problem With Skincare — Even During Quarantine, You Need A 'Daily Dose Of Touch' — Reclaiming Scars As Works Of Art — The Science Of Skin Color

Living In Skin

What does it take to win Olympic gold? To become "the world's fastest human"? This hour, Olympic fame, the politics of sports, and the science of running.

Sprinting for the Finish Line

If you look at a mountain, you might see a skiing destination, a climbing challenge, or even a source of timber to be logged or ore to be mined. But there was a time when mountains were sacred. In some places, they still are. What changes when you think of a mountain not as a giant accumulation of natural resources, but as a living being? Today’s show is part of our project on kinship with the more-than-human world — produced in collaboration with the Center for Humans and Nature, and with support from the Kalliopeia Foundation. You’ll find more information about the project at ttbook.org/kinship and humansandnature.org.

When Mountains Are Gods

Africans are moving into cities in unprecedented numbers. Lagos, Nigeria, is growing by 77 people an hour — it's on track to become a city of 100 million. In 30 years, the continent is projected to have 14 mega-cities of more than 10 million people. It's perhaps the largest urban migration in history. These cities are not like Dubai, or Singapore, or Los Angeles. They’re uniquely African cities, and they’re forcing all of us to reconsider what makes a city modern. And how and why cities thrive. To find out what's going on, we go to Addis Ababa, Ethiopia, to talk with entrepreneurs, writers, scholars and artists. 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 learn how the continent where the human species was born is building the cities of the future. Original Air Date: December 14, 2019 Guests: Dagmawi Woubshet — Julie Mehretu — Emily Callaci — James Ogude — Ato Qyayson — Teju Cole — Meskerem Assegued Interviews In This Hour: Rediscovering the Indigenous City of Addis Ababa — 'People As Infrastructure' — A Tour Of The Networked City — 'I Am Because We Are': The African Philosophy of Ubuntu — How Pan-African Dreams Turned Dystopic — Decoding Global Capitalism on One African Street — Life in the Diaspora: How Teju Cole Pivots Between Cultures — Can Artists Create the City of the Future?

How Africans Are Building The Cities Of The Future

Why don’t we all just take moment to acknowledge that we are collectively exhausted? The pandemic, the protests, the President’s Twitter feed — everything is exhausting.
