In this How on Earth episode, we learn about the latest research on psychedelic mushrooms (psilocybin) and their potential for treating depression. Jill Sjong speaks with Alex Kwan, a neuroscientist and Associate Professor in Psychiatry at Yale University’s School of Medicine, who studies dendritic plasticity in mice using advanced optical methods. Dr. Kwan explains how psilocybin changes the brain, how these changes last long after the psychedelic effects have worn off, and how these results may lead to future treatments for depression.
This week we review the hit movie “My Octopus Teacher,” the story about a man who goes diving in a kelp forest off the Western Cape of South Africa, and becomes acquainted with an octopus. We review the movie with Roger Hanlon, a diving biologist, cephalopod expert and senior scientist at the Marine Biological Laboratory in Woods Hole, MA. We discuss the octopus’ elaborate camouflage and complex behavior. We’ll get some answers to our octopus questions: Do they dream? Do they play? Use tools? Are octopuses a second form of intelligent life on earth?
This week on How on Earth, we look at the shale industry, which has transformed this country in ways we could not have imagined a decade ago. How did this happen? Where do experts think the fracking industry might be going? In this two-part series, we consider why Wall Street and environmentalists are becoming strange new allies.
We interview Paula Noonan from Colorado Watch, the platform for tracking Colorado Legislature. We also listen to excerpts from Bethany McLean, author of Saudi America: the Truth about Fracking and how it’s Changing the World.
