Humans are hardwired to see faces — even in inanimate objects. We have a lima bean-shaped part of our brains dedicated to facial recognition. But this process isn't always straightforward. Science journalist Sadie Dingfelder is one of 10 million Americans who are face blind, or struggle to recognize the faces of people they know. In her new book, Do I Know You? she dives into this, as well as the science of memory and imagination. Want more episodes on the wonder of the human brain?

This summer, scientists have their eyes and telescopes trained on the small constellation system T Coronae Borealis. They think it will explode as part of a periodic nova — a once-in-a-lifetime event according to NASA scientists. And so, with the help of astrophysicist Sarafina El-Badry Nance, we continue our journey farther and deeper into spacetime with a look at the stars: How they're born and how they die. Sarafina has always been drawn to one particular star: Betelgeuse, a red supergiant in the shoulder of the constellation Orion that is nearing the end of its life. What stages of life did Betelgeuse — or any star — go through before it reached this moment? This episode is part of our series Space Camp — all abut the weird, wonderful phenomena in our universe.

About ten years ago, science writer Ferris Jabr started contemplating Earth as a living planet rather than a planet with life on it. It began when he learned that the Amazon rainforest doesn't simply receive the rain that defines it; rather, it helps generate that rain. The Amazon does that by launching bits of biological confetti into the atmosphere that, in turn, seed clouds. After learning this, he began looking for other ways life changes its environment. That led to his new book Becoming Earth: How Our Planet Came to Life. He talks to host Regina G. Barber about examples of life transforming the planet — from changing the color of the sky to altering the weather. Have a story about the environment you'd like us to cover?
