Fireflies create light through a chemical reaction that takes place in specialized cells called photocytes. The light is emitted through a part of the insect’s exoskeleton called the cuticle. Light travels through the cuticle more slowly than it travels through air, and the mismatch means a proportion of the light is reflected back into the lantern, dimming the glow. The unique surface geometry of some fireflies’ cuticles, however, can help minimize internal reflections, meaning more light escapes to reachthe eyes of potential firefly suitors.

The storage capacity of concentrating solar power (CSP) can add significant value to a utility company’s optimal mix of energy sources, a new report by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) suggests.
