| 0:00.0 | Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Curiosity.com. |
| 0:05.8 | I'm Cody Goff. And I'm Ashley Hamer. |
| 0:07.8 | Today you learn about why lightning strikes were vital to the origin of life on Earth, |
| 0:11.8 | how we know a cuddle fish have the power of self-control, |
| 0:15.0 | and why your roommate doesn't know how you're feeling. |
