Parents are supposed to provide the best life possible for their kids, right? But what does that mean when genetic testing for the baby enters the picture? And how far should they go?

The Sound Barrier #4: Listen to the universe
When Wanda Diáz-Merced lost her sight as a college student, she thought her dreams of becoming an astronomer were over — until she learned to listen to space instead.
Wanda is one of several pioneering scientists listening to space. For this episode, we also spoke to Robert Wilson, who used sound to help him discover the first direct evidence of the Big Bang, and Kim Arcand, who plays us what the center of the Milky Way sounds like.

The Sound Barrier #3: What does silence sound like?
