Recently, I posted about how Tamagotchis are making a comeback, and today I have another blast-from-the-past story for you. Any day now, the cicadas are coming! The North American genus of this insect, Magicicada, emerges from the ground only once every 17 years, and this year Radiolab is tracking the U.S. East Coast invasion of this bug with Cicada Tracker, a website that teaches you how to help them predict the emergence of the brood, report when you start seeing bugs, and learn more about cicadas and their life cycle.
