Creatures of Light

In my work translating Santiago Ramón y Cajal’s Café Chats, I came across the following quote: “Like creatures of the deep sea, great geniuses go forth illuminated by their own light.” Cajal is referring to bioluminescence, the ability of certain creatures to produce light without the sun’s energy. Currently, at the American Museum of Natural History in New York City, there is a special exhibition called CREATURES OF LIGHT: NATURE’S BIOLUMINESCENCE, which highlights these amazing organisms. With scaled-up models of fireflies (not flies at all, but rather beetles, you will learn) and iPad videos of a dolphin swimming through sparkling dinoflagellates (some genera of the marine protist become blue-green when jostled), the exhibition provides you with that classic museum experience, one of magic and wonder. At the same time, the science that explains and attempts to explain this complicated trait, which evolved distinctly many times in life on earth, will humble and bewilder.
