Melissa and Jam delve into the fascinating chemistry behind fireflies' bioluminescence. They explore how fireflies produce light through a complex series of chemical reactions involving specific molecules like luciferin and enzymes like luciferase. The discussion extends to how these mechanisms find applications in scientific research, such as identifying tumors in mice. The episode is interspersed with nostalgic summer stories, making it a blend of chemistry education and personal anecdotes.
