Tune into PNAS Science Sessions for a direct line to the people shaping modern science. Produced by PNAS, this podcast offers more than just summaries of published research; it’s where you hear the candid, often personal stories behind the headlines. Each episode features concise conversations with the researchers themselves-from emerging voices to established Academy members-alongside the policymakers whose decisions are informed by this work. You’ll get a genuine sense of the questions that drive these experts, the unexpected hurdles they face in their labs and field studies, and why their findings matter right now. The scope is deliberately wide, reflecting the interdisciplinary nature of science itself, covering discoveries that range from microscopic processes to planetary-scale phenomena. This isn't about dry lectures, but about capturing the human endeavor of investigation. For anyone curious about how science actually unfolds and wants to understand the context of breakthroughs as they happen, this podcast serves as an essential, engaging resource. It connects the dots between a published paper in a prestigious journal and the real-world implications that ripple out from it.
