SciFri
Hosted by Ira Flatow
A long-running public radio show and podcast that makes complex science news accessible through interviews with leading researchers and journalists.
A pillar of American science journalism, SciFri is a weekly news magazine for the intellectually curious. Each episode packages multiple, distinct segments that translate complex topics—from oncology breakthroughs to the chemistry of swimming pools—into digestible conversations. Hosted alternately by Ira Flatow and Flora Lichtman, the show maintains a public radio sensibility, prioritizing clarity and the real-world implications of new research.
“Its public radio heritage gives it an authoritative yet accessible tone that stands apart from more conversational indie podcasts. The format of multiple, unrelated science news segments in a single episode, combined with its live call-in roots, creates a uniquely dynamic and broad-ranging listening experience.”

Notable episodes
- 01Promising new treatments for pancreatic cancer and ALS
A classic SciFri episode format, delivering hopeful news on two difficult diseases with the lead researchers involved, explaining the science and the patient impact.
- 02That chlorine smell at the pool? It’s pee
This segment exemplifies the show's ability to take a common experience, reveal the surprising science behind it, and provide practical health advice.
- 03Under proposed rule, science funding must pass political review
Demonstrates the show's role in covering the crucial, and often overlooked, intersection of science, policy, and politics, framing the stakes with historical context.
What you'll be asked on this show
The show features two primary hosts with distinct but complementary styles. Ira Flatow often opens with a detailed monologue to establish a topic's gravity, using historical analogies to frame its importance. His questions are direct and focus on impact and consequences, probing for timelines ('How soon might patients be able to get this?') and the bigger picture ('How big of a deal is this?'). Flora Lichtman employs a more conversational and sometimes humorous tone. She excels at clarifying technical concepts ('What is air stripping?'), confirming key takeaways for the listener ('So I'm not smelling chlorine, I'm smelling trichloramine?'), and connecting the science to everyday life, often closing with a personal question to the expert ('Do you swim? Has your own research ever given you pause?').
The show is typically structured into several distinct interview segments on unrelated topics. Hosts Ira Flatow and Flora Lichtman share a direct, clear questioning style that prioritizes listener understanding, often framing questions from a layperson's perspective (e.g., 'how soon can they get it?'). The program frequently invites listeners to call in with questions, a holdover from its live radio origins.
