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 Gough. And I'm Ashley Hamer.
0:07.8	Today you learn about why Beauty Sleep has real benefits for your skin,
0:11.4	how plants learn the chemical language of pests to use for
0:14.2	self-defense, and a new algorithm that's fighting deep fakes by looking at heart rate.
0:19.1	Would satisfy some curiosity.
0:20.9	Scientists just discovered why beauty sleep is a thing.
0:25.0	New research suggests that while you sleep your body refreshes its supply of
0:29.3	collagen.
0:30.3	So like beauty sleep is real.
0:31.3	Beauty sleep is real. Beauty sleep is real.
0:33.3	Tell the world!
0:35.2	So this contradicts the scientific consensus around collagen.

0:41.1	For a long time, scientists believe that our supplies of the protein
0:44.4	were fixed. We developed all the collagen we'd ever have by age 17 and then it
0:48.8	slowly deteriorated as we aged. This made sense on the surface. Our skin does get less supple as we get older.
0:56.0	However, collagen isn't just the key to youthful skin.
1:00.0	It actually makes up about a third of the average human's body weight and it plays a million different roles in our bodies.
1:06.0	This protein cushions our joints and gives structure to our bones, including our teeth.
1:11.0	It's also woven into our tendons and our tendons can bounce back
1:15.0	after hard workouts. That swift recovery doesn't fit with the whole theory of
