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 learn super cool stuff. I'm Nate.
0:12.0	And I'm Callie. If you're dropping in for the first time
0:14.3	welcome to curiosity where we aim to blow your mind by helping you to grow your mind.
0:18.1	If you're a loyal listener, welcome back. Today you'll learn about lab-grown meat, a world hundreds of feet below a West Antarctic
0:25.4	Glacier, and a new discovery about the mysterious behavior of ants.
0:30.1	Without further ado, let's satisfy some curiosity.
0:33.6	It is officially barbecue season,

0:58.0	No.

1:20.4	Okay, but why? Well a few reasons. First of all, the world is getting pretty crowded.
1:27.0	By some estimates there will be almost 10 billion people on the planet by 2050 and they all need food and that means protein.
1:34.3	Okay so we need more protein I get that but why does it have to be grown in a lab?
