Talk Nerdy with Cara Santa Maria

Cara is joined for the third time by her dear friend and colleague Dr. Jason Goldman. They talk about the relationship between ecology and cognitive science, including the massive influence human beings have on the planet's wildlife. They also discuss one of Jason's recent stories about a brilliant decoy that could one day defeat sea turtle poachers in Nicaragua.

Cara is joined in studio by UCLA Professor of Information Studies and Design Dr. Ramesh Srinivasan. They talk about themes from his new book, "Whose Global Village? Rethinking How Technology Shapes Our World," including online echo chambers, cultural empathy, and fake news.

On a particularly rainy Los Angeles day, Cara is joined in studio by Dr. Brian Wecht, a theoretical physicist-turned YouTuber and musician (Ninja Sex Party, Game Grumps). They talk about his work in string theory, the intersection of science and music, and the incredible work he does as a co-founder and producer of Story Collider.

Cara is joined in studio by physicist, oceanographer, and BBC television presenter Helen Czerski. They talk about the science of bubbles, the current science landscape in broadcast television, and Helen's wonderful new book, "Storm in a Teacup: The Physics of Everyday Life," in which she explores the foundational physics surrounding us in the simplest everyday objects and experiences.

Cara is joined in studio by Dagny Fleischman, a PhD candidate studying plasmonics and metamaterials at Caltech. They talk about what the field of materials science is and what exciting developments it has to offer (including her own studies of light, color, and specialized image sensors). They also discuss the important work Dagny is doing on campus to improve how student satisfaction metrics are measured and interpreted.

Cara is joined in studio by celebrity makeup artist Val Harvey, who she's also lucky enough to call her friend. What begins as an intriguing conversation about Val's upbringing as a Jehovah's Witness evolves into a frank and telling discussion of race relations in Trump's America.

This week, Cara chats with Michael Marshall of the Merseyside Skeptics Society. They discuss his incredible work both as the Project Director of the Good Thinking Society and the host of the Be Reasonable Podcast. But the primary focus of their conversation is the unholy alliance between journalists and PR companies, as Marsh exposes in his blog "Bad PR."

Cara is joined by Jo Ruxton, the co-founder and Director of Education of Plastic Oceans Foundation, a global network of charitable organizations focused on changing attitudes toward the use of plastics. They discuss the upcoming film, "A Plastic Ocean," which highlights the detrimental effect plastic refuse is having on our marine habitats, and because of that, on our own health and safety. They also talk about ways we can make a difference.

Everyone's favorite astronomer Dr. Phil Plait (Death From the Skies!) is back on #TalkNerdy! He and Cara talk "Bad Astronomy," the movie "Arrival," and what lovers-of-science may have to work against during the new Trump administration.

Cara speaks with the Director of polio eradication efforts for the Bill and Melinda Gates Foundation, Dr. Jay Wenger. They discuss the history of wild poliovirus, including its devastating medical effects, as well as the incredible success of the Global Polio Eradication Initiative. (Oral polio vaccination has reduced cases across the globe by 99.9% since 1988.) In addition, they focus on new cases in Nigeria, and why it is more important than ever to focus on final eradication efforts. To support the effort, visit www.endpolio.org.
