In this deep dive, we uncover the chemical handshake that lets clownfish live safely among venomous sea anemones. We explain how their mucus masks the anemone's sting by keeping levels of the key sugar NU5A (5-N-acetylneuraminic acid) low, how this protective coat is acquired during metamorphosis, and why environmental change threatens this fragile partnership. Along the way we connect the biology to themes of information flow and system resilience — and why tiny molecules can decide big ecol...

Pac-Man: The Yellow Circle That Redefined Gaming and Culture
A deep dive into Pac-Man's 1980 birth, Toru Iwatani's cheerful, nonviolent concept, and the simple yet deep maze-chase that electrified arcades. We unpack the distinctive ghost AI, the Energizer power-up, and how a tiny yellow circle became the first true video-game mascot, sparking a merchandising boom and leaving a lasting cultural footprint—from pop culture to finance with the Pac-Man defense and a place in MoMA. Note: This podcast was AI-generated, and sometimes AI can make mistakes. Plea...
