Why Do a Butterfly's Wings Match? 🦋
Luna and Elodie both noticed that the pattern on one side of a butterfly looks copied onto the other.

Along the way, we'll meet two genes that scientists found by switching them off, and see why the match isn't always perfect. Have a question of your own? We'd love for you to send it to us.

Do Crows Really Hold a Grudge? 🐦⬛
Did you know a crow can remember your face? If it decides you're trouble, it can recognize you years later, and it might tell its friends. Even ones that never met you. Tonight's question comes from Anthony in Okemos, Michigan, who'd heard that crows hold grudges passed down through generations. We find out what a group of scientists in Seattle discovered when they tested it with rubber masks, and why "grudge" turns out not to be quite the right word. Have a question of your own?
