Lisa Menna uses the wonder provoked by her magic tricks to trigger real magic: the kinds of thoughts that can make the world a better place. Having performed in over 40 countries, Lisa and her organization (Cause to Wonder) are working to show people around the world that good things come to those who respect and protect women and girls.

I caught up with Oscar-nominated director Josh Fox in New Orleans (Gasland, How to Let Go of the World and Love All The Things Climate Can't Change), where he's doing his Josh Fox things: writing, organizing political protests against a fracked gas power plant, playing music, creating art (paintings), and eating a lot of crawfish. His cat Sandy joins us to rub her face on the microphones.

Like millions of people, I first became aware of Jeff Leach when I read about his attempt to transfer a hunter/gatherer's fecal matter to his own colon as a way to study the human microbiome. Little did I know I'd find myself sitting at the table with him in rural Texas a few years later or that he'd agree to share his insights with me on a podcast. Jeff's published in Science, Nature and everywhere else a groundbreaking researcher could dream of, but he's too busy with new projects to reflect much on past success.

Cassie and I met John Duarte at a highway rest stop in Dateland, AZ. He was riding his bike from El Paso to San Diego, which is a short "training run" for him. Join us for this spontaneous conversation in the van. #vanthropology2018

Mike has been my best-buddy since I was 15 years old. The Mr. Spock to my Captain Kirk, he's kept me marginally out of trouble for 40 years now. Mike's a talented musician, speaks several languages fluently, and comes out of a confluence of culture and history. There's nobody quite like him.

Bruce Damer is a Canadian-American multi-disciplinary scientist, designer, and author. He collaborates with colleagues developing and testing a new model for the origin of life on Earth and in the design of spacecraft architectures to provide a viable path for expansion of human civilization beyond the Earth.

He has spent 25 years chronicling the history of computing in his DigiBarn Computer Museum and curates archives of counterculture figures such as Dr. Timothy Leary, Terence McKenna and others.
