SciShow Tangents is the lightly competitive knowledge showcase from the geniuses behind the YouTube series SciShow. Every other Tuesday, join Hank Green, Ceri Riley, and Sam Schultz as they try to one-up and amaze each other with weird and funny scientific research... while not getting distracted. There will be tangents about video games, music, weird smells, surprisingly deep insights about life, and of course, poop, but it always comes back to the science.

episode 23: Pregnancy
Pregnancy is, biologically speaking, extremely weird! A pregnant animal’s body goes through so many hormonal and physical changes to make sure a zygote has everything it needs to grow. This week, we’re talking about a few of those things, like why pregnant people get nauseated and other animals might not. So is pseudopregnancy a real thing, or are pandas just tricking zookeepers to get extra treats? Why is there a patent for a birthing machine that looks like a horrible carnival ride? And what the heck is a stone baby?
