For decades, renowned environmental writer Elizabeth Kolbert has taken readers to remote corners of the planet to understand how all life is connected—and how our planet is changing. She’s covered everything from the collapse of insect populations to the success of one town’s effort to go carbon neutral.

Host Flora Lichtman speaks with Kolbert about the undeniable heaviness of our current climate moment, how the splendor of the Great Barrier Reef “tilted” her worldview, and the messy business of trying to solve environmental problems.

In March and April, the Science Friday Book Club is reading Kolbert’s latest book, “Life on a Little-Known Planet.” It’s a collection of essays she’s written over the years. Check out the Book Club to read along.

Guest:

Elizabeth Kolbert is a staff writer at The New Yorker and the author of several books, including “Life on a Little-Known Planet: Dispatches from a Changing World.”

There’s an idea bubbling up in medicine called the “digital twin.” The concept is to take personal health data like genetics, blood test results, tissue samples, MRI scans, and family history, and create a digital model of a patient that can be used to predict how a treatment might work for them. Think personalized medicine supercharged by AI.

For example, cancer researchers are working on models that would create radiation and chemotherapy treatment plans based on the specifics of a patient’s tumor. But these models aren’t ready for the clinic yet, and with so much patient data involved, privacy concerns abound.

Host Flora Lichtman talks with Caroline Chung, a radiation oncologist at the forefront of digital twin research.

Guest:

Dr. Caroline Chung is a radiation oncologist and the co-director of the Institute for Data Science Oncology at UT MD Anderson Cancer Center.

Farmers’ Almanacs have been around for hundreds of years, offering detailed advice about things like the best time to plant certain crops, and when to wean your calves. But do farmers actually use them? Host Flora Lichtman discusses their place in modern life with astronomer and Farmers’ Almanac contributor Dean Regas, and Missouri farmer Liz Graznak.

Plus, zebra finches build their nests with a keen eye for color. But is their style easily swayed by feathered peer pressure? Zebra finch expert Lauren Guillette fills us in.

Guests:

Dean Regas is an astronomer and former Farmers’ Almanac contributor based in Cincinnati.

Liz Graznak is an organic farmer and owner of Happy Hollow Farm based in Columbia, Missouri.

Lauren Guillette is an Associate Professor of Cognitive Ecology at the University of Alberta.

In February, conservationists released 158 young tortoises onto Floreana Island in the Galapagos. The Floreana tortoise subspecies had long been thought extinct, but the discovery of close relatives on another island made a captive breeding effort possible.

SciFri turtle correspondent Charles Bergquist talks with conservationist Penny Becker about the science behind the reintroduction, and what it was like to return the species to an island that had not seen them since the 1850s. Plus, the latest on sea turtle nesting season, and an ancient sea turtle stampede.

Guest:
Dr. Penny Becker is CEO of the nonprofit Island Conservation.

The military use of AI is capturing headlines this month. After a dustup with the Pentagon, the AI company Anthropic is out, and OpenAI is in. Meanwhile, in the US war with Iran, AI is being deployed in ways we’ve never seen.

To make sense of it all, Host Flora Lichtman talks with journalist Karen Hao, who covers AI and is the author of the book Empire of AI: Dreams and Nightmares in Sam Altman's OpenAI.

Guest:
Karen Hao is a tech journalist and author of the book Empire of AI: Dreams and Nightmares in Sam Altman's OpenAI.

On social media, the vagus nerve often gets billed as the gateway to nervous system nirvana: It’s your ticket to better rest, relaxation, and health if you “stimulate” it correctly. Where did this idea come from, and what does the research say?

Host Flora Lichtman talks with neurosurgeon Kevin Tracey, a pioneer of a field called bioelectronic medicine, which uses techniques to stimulate the nervous system with electricity. Back in the 1990s, he was the first to discover that the vagus nerve regulates the immune system and inflammation.

Guest:

Dr. Kevin Tracey is a neurosurgeon, and president and CEO of the Feinstein Institutes for Medical Research at Northwell Health. He is the author of The Great Nerve.

In recent months, AI music has moved from novelty act into the realm of listenable music. For the first time, AI-generated songs from AI-generated artists are on the Billboard top 100 charts, and more musicians are coming out saying they use AI in their songwriting process.

Is this just another tech upgrade to the music-making process or does it signal something bigger in the industry? To investigate, SciFri producer and musician Dee Peterschmidt talks to journalist Kristin Robinson, who covers AI in the music industry, and Laurie Spiegel, an electronic and algorithmic music pioneer.

Guests:
Kristin Robinson is a senior writer for Billboard, based in Los Angeles, CA.
Laurie Spiegel is a composer and programmer based in New York, NY

March Madness is almost upon us, which means basketball arenas across the country will be filled with the thunderous roar of fans and the surprisingly loud squeaks of basketball shoes. At his first NBA game, physicist Adel Djellouli was surprised by the constant noise from the court and wondered, why do basketball shoes squeak? Turns out, the physics of a squeak involves lightning bolts and earthquakes.

Host Flora Lichtman talks with Djellouli about his research and the joy of investigating seemingly simple questions.

Guest:
Dr. Adel Djellouli is an experimental physicist at Harvard University.
