Point of Discovery
About This Show
Point of Discovery takes you on a behind-the-scenes journey to the front lines of science where you'll meet the brilliant, quirky scientists who do it. Our stories are driven by curiosity. How much of our DNA do we share with yeast? How do our brains block out noise at a party so that we can focus on just one person speaking? How do you study a terrible disease-causing bacteria that acts like a saint when you grow it in a petri dish? Come discover the answers with us.

Can Sound Save a Fish?
Gulf Corvina look pretty ordinary—they’re a couple of feet long and silvery. Yet the sounds they make—when millions get together to spawn—are a kind of wonder of the natural world. It’s also why they are in danger. Gulf Corvina live in only one place in the world—the Gulf of California. A decade ago, the Mexican government asked marine biologist Brad Erisman and his colleagues to study the Corvina. They were worried that heavy fishing might cause the population to collapse. When Erisman put a microphone in the water for the first time, he was blown away by the sounds he heard.
