On June 5, 2026, Lulu Miller launched a special crossover episode of Terrestrials on Radiolab, bringing her signature curiosity to the shores of Lake Michigan. In the bonus broadcast, Miller took to a pitch-black park under a full moon to conduct a hands-on experiment in night vision. "Okay. Test, test. It is a very full moon. Um, I'm sitting... You can maybe hear the waves of Lake Michigan. I'm sitting right near the lake in this dark park where there are no, no streetlights, and I'm gonna do the test," she whispered from the field.
The episode also dives deep into the animal kingdom's paternal habits, with Miller marveling at how some species defy traditional parenting roles. Discussing the intricate construction of fish nests, she pointed out how male creatures often handle the gentler duties of raising offspring. "It's clearly arranged with so much care, and I don't know, it just makes me think back to all your worries that started this thing, Michael, that dads don't do the nesting or the cozying or the softer parts," she observed.
While the episode showcases her playful field experiments, it also serves as a reminder of her anchoring role at the network. During the credits, listener Maya reminded everyone that Radiolab is hosted by Lulu Miller and Latif Nasser, cementing her position as one of the show's defining voices as she continues to push the boundaries of narrative science journalism.
