Flavor facts: Why food is so delicious
You might think flavor is what happens on your tongue – and it is. But it’s also so much more. Flavor is influenced by all the senses. How food looks, smells and feels can make a difference. Even the sounds you hear while eating can impact how you perceive taste. We’ll visit a tastebud beauty salon, talk with a chef researcher and do some experiments provided by our friends at America’s Test Kitchen Kids. Plus: a three-part Mystery Sound and a Moment of Um that answers the question: “What makes spicy food spicy?”Note: If you want to do the experiments along with us, congratulations, you can! You’ll need jellybeans, a blindfold and two pieces of dark chocolate. Listen, eat and yum!This episode is a collaboration with our friends at America’s Test Kitchen Kids! They’re sharing access to their “The Nose Knows” experiment with Brains On listeners!

What was the first life on earth?
What was the first lifeform like? What was the first fish or mammal? Is it even possible to know? In this episode, we look to the fossil record to help us trace our roots back to the Last Universal Common Ancestor. Paleontologist Neil Shubin joins us to talk about discovering a remarkably cool fossil that helped us understand how life evolved over billions of years. We also take a field trip to the Hall of Ancestors and examine a few branches on the tree of life. And we learn why figuring out how life began on earth could help us as we find life elsewhere in the universe.This episode is sponsored by Pillsbury Crescent Rolls, KiwiCo (kiwico.com/brains) and Quip (getquip.com/brainson).
