0:00.0	Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Curiosity.com.
0:06.0	I'm Cody Gough.
0:07.0	And I'm Ashley Hamer.
0:08.0	Today you learn about new research into how social anxiety works in the brain,
0:12.0	how scientists develop the first synthetic self-replicating genome, and the
0:16.7	adorable sounds penguins make underwater.
0:20.0	They're super cute.
0:21.4	What's that us satisfy some curiosity.
0:23.0	According to a new study, people with social anxiety have a harder time remembering social interactions
0:30.4	that ended well.
0:32.0	And that tells us more about how social anxiety works in the brain.
0:36.0	And that could help us come up with better ways to deal with it.
0:40.0	When someone with social anxiety is about to enter a high-stakes social situation,
0:45.0	like meeting the in-laws or doing a big work presentation,
0:48.0	they're often flooded with memories of situations that ended badly in the past. This can feel pretty discouraging and a little
0:57.0	like self-sabbatage. But new research from the University of Waterloo suggests that people with social anxiety
1:04.0	actually have a harder time remembering positive social interactions.
1:08.0	It's a memory bias.
1:10.0	The good happy social memories are harder to retrieve.
1:14.0	For this study, researchers asked 197 participants to imagine themselves in a few fictional social scenarios,
1:21.0	like going on a blind date or attending a house party and
1:25.0	some fictional non-social scenarios like making dinner alone or getting a bill in the mail.
