0:00.0	Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.
0:08.5	Time flies when you learn in super cool stuff.
0:10.5	I'm Nate.
0:11.5	And I'm Callie. If you're dropping in for the first time, welcome to curiosity where we aim to blow your mind by helping you to grow your mind. If you're a loyal listener, welcome back.
0:20.0	Today you'll learn about a breakthrough in embryo modeling, a breathing ball that could take the edge off of anxiety, and the fall of a dynasty.
0:29.0	Without further ado, let's satisfy some curiosity.
0:32.0	Researchers from the Wiseman Institute of Science in Israel have created the first ever 14 day old human embryo.
0:39.0	But literally every single person who ever lived on the planet was a 14 day old embryo at one point.
0:47.0	Did I mention that this embryo didn't come from a mother and a father?
0:50.0	It was grown from stem cells.
0:52.0	Ah ha, you didn't mention that.
0:55.0	We've talked about this on the show before.
0:57.0	Scientists are using stem cells to grow organs and limbs and treat diseases and do all kinds of things.
1:03.0	Yes, but did I mention that this isn't actually an embryo?
1:07.0	It's a lab-grown model of an embryo.
1:10.0	Okay, well, you know you didn't mention that.
1:12.0	Come on.
1:14.0	All right, wait a second. So this is starting to get weird. Let me get a straight.
1:17.0	Scientists in Israel used stem cells to grow a model of a human embryo.
1:23.7	Exactly.
1:24.7	It turns out it's actually a major breakthrough because despite the billions and billions of people
1:29.3	who have been born, we actually don't know all that much about this period of pregnancy.
