Entertaining conversations about science, technology and other stuff that’ll blow your mind and help you make sense of our weird, fascinating world. From supermassive black holes to superbugs, Science Friday brings you the latest in science news and connects you with leading experts to dig deeper. The show is hosted by Ira Flatow and Flora Lichtman, and is distributed by WNYC Studios to over 500 public radio stations across the country.
MIT astrophysicist Dr. Sarah Seager discusses the scientific rationale for primitive life existing in Venus's sulfuric acid clouds, where temperatures are surprisingly habitable, and details the Morning Star Missions designed to detect complex organic molecules and eventually return samples to Earth.
Robotics PhD Daniel H. Wilson discusses his sci-fi thriller "Hole in the Sky," exploring humanity's confrontation with incomprehensible cosmic entities through military, scientific, and Cherokee worldviews, while reflecting on his pivot from engineer to author.
Geneticist Mary-Claire King traces her journey from childhood math puzzles to groundbreaking discoveries, revealing how mentorship helped her persevere through PhD failures, how she proved humans and chimps share 99% of protein-coding DNA, and how the 1973 Chile coup redirected her toward cancer genetics.
Nobel laureate Dr. Francis Arnold revolutionized chemistry by developing directed evolution, a method to breed enzymes like livestock for specific industrial tasks from laundry detergents to pollution cleanup. She predicts that within 5-10 years, AI integration will enable scientists to 'vibe code' enzymes capable of performing virtually any chemical transformation on demand.
Author Daisy Hernández discusses her investigation into Chagas disease—a parasitic illness more prevalent in the U.S. than Zika yet virtually unknown to Americans—revealing how systemic "epidemiological divides" actively determine who receives care and who is left to suffer from treatable diseases based on wealth, geography, and immigration status.
Physicist Sean Carroll discusses his book 'The Biggest Ideas in the Universe,' which bridges the gap between metaphor-heavy popular science and intimidating textbooks by teaching actual physics equations to readers with only high school algebra, proving that authentic mathematical understanding of concepts like general relativity is accessible without professional training.
Physicist Sean Carroll argues that engaging directly with mathematical equations—not just metaphors—is essential to grasp modern physics, from the relativistic nature of time and unresolved quantum paradoxes to the mysterious dark matter and energy that comprise 95% of the cosmos.
Nobel laureate Venki Ramakrishnan argues that while molecular biology has revealed specific mechanisms driving aging, extending maximum human lifespan remains uncertain and raises profound ethical concerns about inequality; the priority should be extending healthspan rather than pursuing radical longevity.
