By light of luciferin and luciferase

Though this post strays far afield from my Walker-centric focus, it merits mention because fireflies, to me, are the very symbol of fleeting summer. Their bioluminescence results from the reaction of two chemicals, luciferin and luciferase. Let this be a challenge to you to venture outdoors in the evening to spot these insects that are homely by day and hypnotic by night.
