0:00.0	Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.
0:09.0	Time flies when you're learning super cool stuff. I'm Nate, and I'm Callie. If you're dropping in for the first time
0:14.4	welcome to Curiosity where we aim to blow your mind by helping you to grow your mind.
0:18.3	If you're a loyal listener, welcome back. Today you'll learn about how rockets are
0:22.4	preventing the ozone layer from healing properly,
0:25.0	how researchers are figuring out the smells of the ancient world,
0:29.0	and how Mother Orca whales take care of their sons to ensure the survival of their species.
0:34.3	Without further ado, let's satisfy some curiosity.
0:37.3	Good news everyone!
