Episode 157 - Bioluminescence and Biofluorescence

Glowing organisms might seem like something out of science fiction, but not only do they exist here on Earth, they are incredibly common. Some species glow when exposed to certain kinds of light, and others produce their very own light in the darkest habitats on the planet. This episode, we explore glowing life: how they do it, what they use it for, and what we can tell about how this remarkable ability came to be.
In the news: painted turtles, dinosaur herbivores, human brains, and insect ears.
