Brain Trust (starts at 4:23) When you are trying to make a decision about something important or having a disagreement with someone, don’t you sometimes wish you had a scientist with you – a world expert on the topic at hand – to help you out? In fact, it would be great to have dozens of experts in many fields available, sort of your own personal Brain Trust. Well, luckily Garth Sundem can help you out with his book called: “Brain Trust,” where he has interviewed 93 of the top scientists in fields like physics, genetics, cognitive science, economics, nutrition, mathematics, and talked to them about very important topics in their fields. And not the easy topics like Higgs Bosons, Fermat’s Last Theorem, and inflationary cosmology, but rather the much more difficult – and immediately useful – topics like: the best design for a paper airplane, how to survive Armageddon, how to create giant man-eating plants, successful dating techniques (and we don’t mean carbon dating), and how to tell when someone is lying. Host Joel Parker talks with Garth about his book.
Drought (starts at 15:10) Given all the rain and snow on the Front Range and beyond lately, you’d think that Colorado is emerging from the persistent drought, right? But last year was one of the hottest and driest on record in the state and some regions have yet to recover. Among those who have suffered the most from the persistent drought are farmers and ranchers. In fact, some have sold off cattle and even shuttered their businesses. That said, high prices have boosted profits for some wheat farmers, for instance. To find out just how badly many farmers and ranchers have been hit by the drought, researchers at Colorado State University have been surveying them annually for a while. Host Susan Moran talks with Christopher Goemans, a resource economist in the Department of Agricultural and Resource Economics at Colorado State University, and Ron Nelson, a graduate student also at CSU, about a recent survey of drought conditions and the broader environment.

Today on How On Earth, KGNU’s award-winning science show, we continue our discussion with Boulder’s Dr. David Wineland about the human side of winning the Nobel Prize. The National Institute of Standards and Technology scientist shared the 2012 physics award with France’s Serge Haroche. They’ve developed experimental methods for trapping and holding particles so that weird quantum behaviors can be studied. The research is critical to developing extreme quantum computers that may someday break today’s best encryption algorithms…and make truly unbreakable ones.

Mapping Pain in the Brain (starts at 7:30 )
If you hit your thumb with a hammer, you feel physical pain. Terrible sunburn? Pain. A muscle cramp? Pain. In each case, you know it’s pain. But how a body senses this pain has been elusive. Surgeons have tried to cut out what they think of as the brain’s pain center. This often doesn’t work, and it has side effects. Painkilling drugs? Sometimes they help, sometimes they cause addiction. Understanding the brain’s pain circuits might help scientists find better ways to deal with pain. Last week, CU-Boulder researchers took a step in that direction by publishing a magnetic resonance imaging map that they believe shows the signature of physical pain response within the brain. The lead researcher on this project is Tor Wager. Wager is the director of the Cognitive and Affective Neuroscience laboratory at the University of Colorado, Boulder.

Welcome to a special episode of How On Earth with Dr. Seth Shostak, the Senior Astronomer at the Search for Extraterrestrial Intelligence Institute. We’ve been listening for their tell-tale signal for 50 years with no luck, but Seth says that he’ll bet a cup of coffee we’ll hear from them in the next few decades. We explore what might happen if we find these brainy aliens or if we don’t find them at all. It’s part of the Conference on World Affairs.

The Universe Within (starts at 4:40) Within each and every one of us is the history of life on this planet, the planet itself and the entire universe. This is the theme of a new book “The Universe Within.” The author, Neil Shubin, is a professor of Paleontology and Evolutionary Biology at the University of Chicago. Starting with what physically constitutes a human being and what makes a human life possible, Shubin surveys many domains of science to find out what we can learn about what’s out there from what’s inside of us. It’s a fantastically broad scope, bringing together the common history of Rocks, Planets and People. As professor Shubin explains to How On Earth’s Chip Grandits, it is the very concept of this common history that binds all of these topics, which are normally found scattered throughout disparate domains of science and academia.
De-Extinction (starts at 14:15) You may think that when a species dies, it’s gone forever. But with enough motivation, scientists might be able to return some species to life. Popular science writer Carl Zimmer has written about “de-extinction” in the cover story of April’s issue of National Geographic magazine. So, is the movie Jurassic Park a good primer on de-extinction?

Tom’s River (starts at 5:03) Susan Moran interviews Dan Fagin, author of the new book Toms River: A Story of Science and Salvation. You’ve likely heard of the chemical contamination of Love Canal at Niagara Falls, in the mid-1970s. And the leukemia cluster linked to water pollution in Woburn, Massachusetts,in the mid-80s — made famous by the book Civil Action. But you may not have heard of another cancer cluster –- also linked to industrial chemicals – this one in the small town of Toms River, N.J. Fagin’s book about Tom’s River is far more than a gripping investigation of one town’s struggle; it is a cautionary and illuminating tale about the complexities of finding a causal, not just associative, link between pollution and cancer. And it is a story for anyone concerned about whether the air they breathe, and the water they drink is in jeopardy.
2013-03-26 Making Fire on KGNU’s How on Earth Science Show from Shelley Schlender on Vimeo.
Making Primitive Fire (starts at 15:40) Roger Wendell interviews Michael and Lorritta Slayton, who are longtime practitioners of primitive fire making and survival skills. Teaching at rendezvous, schools, and outdoors shows Michael and Lorritta have delighted thousands with their “Backup to the Bic” demonstrations – how to create a lifesaving fire during an emergency when matches and high-tech lighters won’t do the trick. Primitive fire making focuses on very old, but tried and true ways of making fire. Today, Michael “Big Smoke” and Lorritta “Flint Woman” Slayton will teach us about Bow Drill Fire Sticks and the flint-and-steel methods for creating fire – assuring us that what we learn from the past will make us wiser for the future.

Facing the Wave (starts at 04:50) Yesterday marked the two-year anniversary of the devastating earthquake and tsunami that rocked and partially devoured the northeastern coast of Japan. Although prone to earthquakes, the Tōhoku event hit a magnitude of 9.0, tying it for fourth largest earthquake on record according to the United States Geological Survey—a magnitude greater than scientists thought possible for this region.
Last month, co-host Beth Bartel spoke with author Gretel Ehrlich about her recently published book “Facing the Wave: A Journey in the Wake of the Tsunami.” When asked about her motivation to write this book, Ehrlich, a long-time traveler to Japan, said simply that she went to see the effects of the wave because she had to. (Go to our extended interview for more about how the disaster spurred activism in Japan.)
Pandora’s Lunchbox (starts at 14:38) Did you ever think how long that energy bar you ate while skiing recently would last in tact beyond the expiration date? Or that bag of Oreo cookies you devoured last night? Melanie Warner, a local journalist and former staff writer at the New York Times, started thinking about it so much that she began experimenting with leaving some processed foods out way beyond their expiration date. What she found was shocking, and led her to explore deeply into the “processed food industrial complex.” The result is a new book called “Pandora’s Lunchbox: How Processed Food Took Over the American Meal.” Co-host Susan Moran interviews Warner about the creators and health impacts of many iconic foods in the American diet.
