Exploring the Deeper End of Ideas
Science and Technology
Richard Powers’ “The Overstory” is overturning a lot of conventional thinking. It’s been called “visionary” and “monumental” — and it earned him the 2019 Pulitzer Prize in fiction. Though human characters shape the plot of this 500-page epic, the real heroes are trees.More
Suzanne Simard is a forest ecologist who's revolutionizing our understanding of trees. She has discovered that trees use underground networks to communicate and cooperate with each other. It turns out that whole forests can exist as a superorganism.More
Do you know what an earthquake sounds like? Geophysicist Ben Holtzman collects recordings from around the world — from the Fukushima disaster to the manmade earthquakes caused by fracking. We hear examples of these seismic rumbles.More
Robert Macfarlane spent a decade exploring caves, mines, catacombs and sewers, on a quest to discover the deep underground. He found a subterranean world of wonder and horror.More
Jill Heinerth nearly died when she was trapped by ocean currents inside an Antarctic iceberg. She's one of the world's most accomplished underwater cave divers, often exploring caves no one's ever been in, which show her "the veins of the Earth."More
Steve asked a panel of experts— social psychologist Michelle Shiota, writer Caspar Henderson, and astrophysicist Alex Filippenko — to unpack the emerging science behind the emotions of awe and wonder, including their role in our ongoing quest for understanding and knowledge.More
Could being digitized be a way for all of us to become immortal? Maybe, but not in a way we would particularly enjoy, as this story from listener Mark Pantoja illustrates.More
How A Novel About 'Monster Dogs' Can Help Us Rethink Our Relationship with Our Own Canine Companions
Kirsten Bakis first wrote her story of biomechanically-enhanced, hyper-intelligent dogs 20 years ago, and it’s been a cult favorite ever since. So why create a post-modern Frankenstein story with dogs at the heart of the tale?More
Social scientists are finding that generating happiness in your life may have less to do with an arbitrary number — like your bank account or how many Instagram followers you have — and more to do with how well you connect with the people around you.More
Psychologist Laurie Santos created a college course to teach students how to use what scientific research has discovered about what makes us happy and why. It became the most popular class in the 300 year history of Yale.More
Gavin Francis is fascinated by the complexity and beauty of the human body, which is so finely engineered that it can seem almost miraculous.More
Missy Makinia donated her kidney to whoever might need it. Her transplant surgeon — Josh Mezrich — invited Shannon into his operating room to see firsthand what it takes to remove and transport a human kidney.More
Novelist Siri Hustvedt knows how the creative process feels. Neuroscientist Heather Berlin knows what it looks like in the brain. Together with Steve, they explore the emerging science of creativity.More
Before John Muir and Charles Darwin, there was Alexander von Humboldt, the German scientist who shaped our understanding of nature. Now, he’s largely forgotten, but biographer Andrea Wulf says he was once the world's most famous scientist. More
Botanist Robin Wall Kimmerer says there is a reason so many around the world consider corn to be sacred. We give it life, and in return, it gives us life. She says the industrial-scale farming of America has lost control of that balance.More
There is an unusual, giant corn in southern Mexico that gets its own nitrogen from the air — no manufacturing required.More
Most of us get our food from the grocery store, not the fields where it grows. But if you really want to understand where our food comes from — and the potential threats to the food supply — you have to think about seeds.More
