Jim likes to think big - about big ideas, big challenges, and bigger solutions! In this episode, Jim Green and Alan Alda talk about planetary exploration and how life itself survives and thrives in the strangest of places. Support the show: https://www.patreon.com/clearandvivid

Unconscious bias is a widely used term and, too often, not well understood. It can be devastating for those it impacts. And coming to grips with unconscious bias in our own thinking can be unsettling. Like many others, Alan Alda found it hard to believe that the unconscious bias test he took accurately reflected his own thinking. So, to find out more, Alan sat down with Dr. Kuheli Dutt, who is meticulous in her research into the hidden biases we all have. Dr. Dutt is the Diversity Officer at the Lamont-Doherty Earth Observatory at Columbia University and has written about how these unconscious biases can distort judgments about who can be a scientist – to the detriment of science itself.

How do you interview an octopus for a podcast? We're pretty sure that Alan Alda's interview with Ruddy, a giant pacific octopus, who lives at the New England Aquarium is a first for a podcast.

Sy is the author of the New York Times bestseller, "The Soul of Octopus." She's an expert on creatures great and small and what we can learn about communication, observation, and humility from the other animals in the kingdom.
