Radiolab is a radio program broadcast on public radio stations in the United States and through a podcast available internationally, both produced by WNYC. Hosted by Latif Nasser and Lulu Miller, each episode delves into scientific and philosophical topics through stories, interviews, and thought experiments.
Radiolab airs as a one-hour broadcast each week while its podcast releases new episodes of varying lengths usually biweekly. For a few years, the Radiolab podcast feed featured a full-hour episode every six weeks, announced by the hosts as Radiolab: The Podcast, interspersed with two shorter pieces known as "shorts." These shorter pieces were often combined into full episodes not found on the podcast feed but available on Radiolab's website. Recently, Radiolab has diversified its podcast format, combining these episodes and shorts into an airable compilation. The program is syndicated to over 450 NPR affiliates nationwide.[1]
Radiolab's first nine seasons (February 2002–April 2011) comprised five episodes each. Subsequent seasons contained between nine and ten episodes.[2][3]
