Dreamland

Feb 4, 2013

Humans spend nearly a third of their lives sleeping. Most of us love sleep, and yet we have little idea how it affects us. Indeed, sleep is largely a mystery. Even scientists don’t know why, exactly, we need to sleep. The reporter David Randall tours the Land of Nod in a new book, exploring the odd, sometimes disturbing and often fascinating things that happen when we’re in dreamland. That’s actually the name of the book—Dreamland—and Randall joins Doug on Monday to talk about it. (Rebroadcast)

Anesthesia is often cited as one of the greatest advances in modern medicine. However, every once in a while, something goes wrong and a person wakes up in the middle of a procedure. The results can be deeply traumatic. The truth is, we don’t know how some anesthetic medicines work. But if we could find out, not only would patients remain safely comatose, the journalist Joshua Lang says we’d also close in on some deep questions about what it means to be conscious. Lang’s written an article about anesthesia and consciousness and he joins us Tuesday to discuss it.

Hallucinations

Jan 14, 2013

In his latest book, the neuroscientist Oliver Sacks writes about his own history using psychoactive drugs. He’s said that apart from being both pleasurable and dangerous, those experiences gave him empathy for his patients suffering from hallucinations. Sacks says hallucinations are far more common than we realize, and his book is filled with bizarre encounters with the unreal brought on by disease, syndromes and disorders. Doug talks to Oliver Sacks about the many and fascinating ways we perceive things that aren’t there. (Rebroadcast)

A few years ago, the writer Steve Hendricks felt overweight, and he resolved to shed 20 pounds. His weight loss method might strike some as reckless: he fasted for over three weeks. Vanity, he writes, wasn't his only concern. He was informally testing theories which suggest that fasting can alleviate numerous maladies and symptoms and improve general health, much like exercise. Hendricks wrote about the benefits of an empty stomach for Harper's. Doug talked with him about it in March, and we're rebroadcasting that conversation on Friday. (Rebroadcast)

Spillover

Dec 27, 2012

Thursday, Doug’s joined by the science writer David Quammen. Twelve years ago, Quammen began researching the concept of “spillover,” the sudden transfer of disease from one species to another. He traveled around the world, investigating the science, history and human impact of diseases like AIDS, SARS and Ebola. In his newest book, Spillover, Quammen says that what he’s learned makes clear “the old Darwinian truth that humanity is a kind of animal, inextricably linked with other animals: in origin and in descent, in sickness and in health.” (Rebroadcast)

David Strayer has known for a long time that there's a restorative power in nature. The University of Utah psychologist is an avid hiker, but his latest research quantifies the benefits of turning off your technology and getting outdoors. After 4 days in the wilderness with no cell phones, laptops or gadgets, people were 50% better at creative problem-solving. On Monday, Doug talks to Strayer and Stanford's Clifford Nass about how technology may be rewiring our brains and what we can do about it.

Doubting Bigfoot

Dec 10, 2012

When we spoke last year with anthropologist Jeffrey Meldrum about his research on Bigfoot, not all of our listeners were impressed. Among them was science writer Brian Switek who says that focusing on fantastic tales comes at a cost: it blurs the line between belief and scientific method and it distracts us from the astonishing species that do exist. Well, Sasquatch is in the news again and Tuesday, Switek joins us to explain why rumors of Bigfoot DNA don't impress him either.

When photographer James Balog first headed to the Arctic for National Geographic in 2005, he says he was a skeptic about climate change. What he saw there though put his career on a new course. Balog is the founder of the Extreme Ice Survey – a project that captures visually dramatic manifestations of climate change. Thursday, Balog and filmmaker Jeff Orlowski join us to talk about the stunning documentary "Chasing Ice," which follows James Balog as he risks his life to document the impact of warming temperatures on the world's glaciers.

Who hasn’t watched a bird soaring on high, swooping through the sky, and wondered what it would feel like to fly on feathered wings? In his book Bird Sense, the behavioral ecologist Tim Birkhead takes an inside look at the life of birds. He details the extraordinary senses, emotions and abilities of robins, finches, ducks, chickens and other avian friends. Birkhead joins Doug on Thursday to examine what it’s like to be a bird and what it's like to share a planet with such utterly different and yet recognizably similar creatures.
