Why did conventional thinking in aerodynamics fail to explain how insects fly? What can robots teach us about how insects do it? How do insect brains direct their incredible aerial feats and get around in the world? Michael Dickinson is a biologist at Caltech who uses robots to study how insects fly. More recently, he has focused on insect neurobiology and behavior. On this episode, Art and Marty talk with Michael about the mysteries of tiny insect flight, and how the presumably simple brains of such animals enable them to navigate sometimes vast distances.

How does a tiny insect migrate thousands of miles from Canada to Mexico each year? What does the decline of monarch butterflies tell us about the ecological health of our continent? How are scientists using gene editing to understand how insects have evolved to tolerate poisonous plants? Anurag Agrawal is a biologist at Cornell University who studies plant-insect interactions, including monarch butterflies. He is the author of a new book called "Monarchs and Milkweed: A Migrating Butterfly, a Poisonous Plant, and Their Remarkable Story of Coevolution.” On this episode, Art and Marty talk with Anurag about the incredible migration of the monarch butterfly, the recent decline in population and a fascinating study where scientists edited the genomes of fruit flies to make them resistant to a poisonous plant that monarchs eat.

What does neuroscience have to say about morality, politics, and cross-cultural communication? How are neurobiology and philosophy connected? Pat Churchland is a neurobiologist and philosopher at UC San Diego, where she has spent years studying connections between mind and brain. Tune into this episode to hear Marty and Art discuss these questions as well as Pat's new book "Conscience: The Origins of Moral Intuition."

Why hasn’t natural selection eliminated human diseases? Are bad feelings like anxiety and depression adaptive? Can we use evolutionary biology to improve medicine? Randy Nesse is a doctor and a scientist at Arizona State University who uses evolutionary biology to inform the practice of medicine. In his latest book, “Good Reasons for Bad Feelings,” he discusses how natural and sexual selection may have shaped our psychological and emotional lives. On this episode Art and Marty talk to Randy about evolutionary psychiatry.

Why are animals loud and conspicuous when that increases their risk from predators? How does noise pollution affect mating behaviors? How can robots help biologists study complex topics such as sexual selection and mate choice?

Gail Patricelli is a behavioral ecologist at UC Davis, where she studies how individual variation in animal signaling and communication affects mate choice and reproductive success. Gail uses robots to investigate the process of sexual selection in sage-grouse and other species with elaborate mating displays.

Is intelligence similar in humans and dolphins? Do dolphins and whales have their own culture and language? How do they perceive the world around them? Janet Mann is a biologist at Georgetown University, where she studies how dolphins form social groups, use tools, and communicate with one another. Tune into this episode to hear Marty and Art talk to Janet about these topics and Janet’s book, Deep Thinkers: Inside the minds of whales, dolphins, and porpoises.

Why do some rove beetles look like ants? Why do living things evolve similar solutions to common problems? Is there predictability within the evolutionary process? On this episode, Art and Marty talk with Joe Parker, an entomologist at Caltech. Joe has been collecting beetles since the age of 16, when he first became amazed by their incredible diversity. He now focuses on rove beetles and studies their evolutionary relationship with ants to understand how different species converge upon similar traits.

How does our indoor, modern lifestyle affect our microbiome? How does this novel microbiome affect our health? On this episode, Marty and Art talk with Rob Dunn, an applied ecologist at North Carolina State University. Rob studies the organisms that we come into contact with every day, from the microbes in our bodies to the insects in our homes. Tune into this episode to hear Marty and Art talk to Rob about the crazy diversity of microbes on our skin and its importance in our health and our food. Many of the ideas we discuss are from Rob’s most recent book, Never Home Alone.
