Could that concept improve the efficiency of light-emitting diodes (LEDs), which are used in electronic devices? To find out, scientists coated LEDs with a corrugated surface similar to that of the firefly’s lantern. The result? The LEDs emitted up to 55 percent more light! Physicist Annick Bay says: “The most important aspect of this work is that it shows how much we can learn by carefully observing nature.”
What do you think? Did the lantern of those Photuris fireflies come about by evolution? Or was it designed?
