Kgnu - How On Earth

This is an extended version of the interview with researchers at Harvard and the University of Massachusetts, which indicates that out in the real world, people who use nicotine replacement therapy in the hopes of an easier “quit” don’t fare any better than people who use will power and community support.  Some people who use nicotine replacements are actually MORE likely to relapse.  Here, Shelley Schlender talks with Lois Biener, a Senior Research Fellow at the Center for Survey Research at the University of Massachusetts Boston.  Her research was published in the journal Tobacco Control.  

  We hear about a book called Logicomix, featuring Christos Papidimitriou, who is one of the world’s leaders on computational complexity theory, and what happens when he consents to be interviewed by two 10-year olds.  And in the headlines, we delve into a new report published in the January issue of Archives of Pediatrics & Adolescent Medicine that indicates exercise helps kids do better in school.  We fly to the moon with two GRAIL spacecraft, which stands for "Gravity Recovery and Interior Laboratory."  And we invite you to sign up for the free, “Mini Med-The Clinical Years,” being offered at the CU Medical Center.

Mining retention pond in Colorado. Image courtesy of the EPA. Clean Water Struggles. Co-host Susan Moran interviews journalist Judith Lewis Mernit about how small rural communities in the West are struggling to afford complying with federal water-quality standards as they relate to water pollutants. Mernit wrote an article on the topic in High Country News' Dec. 12 issue. She explores the unintended consequences of complex federal  standards, which place a disproportionately heavy burden on small communities.  A big bone of contention, and a source of a flood of lawsuits, is a provision in the Clean Water Act that forces states to assess their impaired waterways and set maximum limits, or loads, for nitrates and other pollutants in them. 2011's Big Sci-Enviro-Tech Stories. In the second feature co-hosts Susan Moran and Tom Yulsman are joined by How On Earth's Tom McKinnon and Shelley Schlender, as well as photojournalist Michael Kodas (author of a forthcoming book on megafires) to reflect on 2011's major

  We take a look at favorite holiday sci-tech gifts, including the SparkFun Inventor’s Kit, Logicomix, Manga Guide to Electricity, Lego Mindstorms,  a fun new novelty for anyone on your list - giant microbes.  After the show, we also voted to add yet one more item to your last-minute gifts - a mesh bag of any size, for . . . what else?  Catching neutrinos. Also on the show this week,  How on Earth's Roger Wendell describes a new way to clean irrigation ditches, called, a "Self Cleaning Trash Screen for Irrigation Water (Watch on You Tube)." Local author and scientist Dick Williams talks with How on Earth's Chip Grandits about Dick's new book:  Eating Your Heart Out?  Williams, with coauthors Binx Selby and Linda Fong.  In his book, Dick writes, "For over a half-century, careful scientific researchers have known what a good balanced diet really means, yet most of us have largely ignored this important information. We have preferred to continue in our culturally determined ruts, eating ourselves to death

In last month’s election, Boulder voters gave the go-ahead for the city to move forward on municipalizing the electrical utility.  The chief motivation for that decision was to put more renewable energy on the grid.  There are a large number of policy options to incentivize renewable energy – so many that it’s hard to keep them all straight.  John Farrell, a Senior Researcher at the Institute for Local Self-Reliance, joined us by phone to explain the situation.  (interview begins at 6:25) Mountainous areas like the Rockies are hotspots for plant and animal biodiversity but as the climate warms many of these species – including Colorado’s iconic pica -- are under threat.  Much research has focused on the effects of temperature change, but less has focused on the interactions of temperature and precipitation in a changing climate.  University of Colorado biologist Christy McCain is closely examining those inter-relationships.  She’s been studying patterns of diversity for plants and critters on mountains around

Jim Motavalli joins us by phone from his home in Fairfield, Connecticut.  Jim is the author of a new book titled "High Voltage: The Fast Track to Plug In the Auto Industry" and helped us sort out some of the issues around EVs.  Mr. Motavalli is an auto journalist who writes for the New York Times, Car Talk, the Mother Nature Network and PlugInCars.com.  Jim has been covering the emerging electric vehicle industry for the last decade.   He reported that if he finds some extra money in his sofa cushions he'll be buying a Tesla Roadster.   Rodale Press has donated some copies of "High Voltage" as premiums for new and renewing members.  Give us a call at 303-449-4885 and you'll be reading Jim's book faster than you can charge up your Nissan Leaf. (Motavalli interview starts at 4:39). Shelley Schlender visited with Colorado State University Scientist and Paleolithic Lifestyle expert Loren Cordain to talk about acne prevention.    Cordain asserts that the best “prescription” for preventing acne is to eat the foods

One often hears people state "I'm not good at math" or that they don’t like math because it they don’t think it has any relevance to their day-to-day life (other than, maybe, to balance a checkbook). However, both of those myths are addressed head-on in a new book titled "Math for Life: Crucial Ideas You Didn’t Learn in School." The author of that book is Dr. Jeffrey Bennett, an astrophysicist and educator. He has written several text books and books for the general public including the popular series of children’s books ("Max goes to the Moon" and other places around the solar system) and now another new children’s book called "The Wizard Who Saved the World." We are happy to have Jeff back on our show in this episode to talk about the importance of math to how we make decisions in our personal lives, in our community, and in Congress...and about being a Wizard.

In celebration of Thanksgiving, Beth Bartel interviews Stan Baker of the National Wild Turkey Federation about wild turkeys in Colorado. You may be surprised at the story of the wild turkey in North America and just how different the wild turkey is from the domestic turkeys we're used to. There's a reason Benjamin Franklin wanted the turkey, not the bald eagle, to be our national bird. Can light pollution at night lead to air pollution during the day? Jim Pullen talks with researcher Harald Stark of the Cooperative Institute for Research in the Environmental Sciences (CIRES) to find out. Stark's work has taken him over Los Angeles to measure the chemistry of the night sky. What he is learning increases our understanding of ground-level ozone, which is a major pollutant of our urban air.

Susan Moran has a telephone interview with Cynthia Barnett.   Cynthia is a journalist and author of Blue Revolution: Unmaking America’s Water Crisis.” She calls the U.S. one of the most “water-wasting places on the planet.” But in her book she also draws from positive examples of water conservation in the country to propose a new “water ethic.”  (start - 4:20). . . Jeff Branson of the SparkFun Electronics Department of Education joins Tom McKinnon in the Boulder studio to discuss the so-called Maker Movement.  In particular, he describes how it is revolutionizing K-12 education.

Feature #1 (time mark 5:30)  When people think of Colorado, they usually don’t think about “oceans”.  After all, Colorado doesn’t have much of a coastline these days, though it was definitely had oceanfront property a few hundred million years ago.   However, being in a landlocked state doesn’t mean that there isn’t any thing we can do to impact the health and ecology of the ocean and marine biology.  Co-host Joel Parker talks with  Vicki Goldstein, founder and president of the Colorado Ocean Coalition about the "Making Waves in Colorado" symposium and what all of us around the world (leaving near or far from oceans) do that impact and can help oceans. Feature #2 (time mark 14:10)  Nitrogen - we can't live without it, but you can have too much of a good thing. In its gaseous form nitrogen is harmless and makes up nearly 80 percent of the atmosphere. The worldwide population never would have reached 7 billion people without nitrogen, in the form of chemical fertilizer. But excess nitrogen –from fertilizer run

Today, November 1, we offer two features. Feature #1: Co-host Susan Moran interviews Jonathan Jarvis, director of the National Park Service, who discusses NPS' quest to lure more people to urban parks, not just the iconic national parks such as Yellowstone and the Grand Canyon. These "threshold" experiences can lead people to appreciate, and help preserve, nature, including national parks. He also speaks of the NPS' efforts to save the most threatened national parks, especially the Everglades. Listen to the extended version of the interview here. Feature #2: A python’s remarkable ability to quickly enlarge its heart and other organs during digestion is leading scientists at the University of Colorado in Boulder to uncover potential new therapies for heart disease. Their research was recently published in the journal Science. The new study also offers clues to how a special combination of fats found in normal foods just might end up as a powerful drug someday for helping a failing heart. How on Earth's S

Tom McKinnon and Peter Asmus of Pike Research discuss electrical utility municipalization from a national perspective.  Peter adds an interesting statistic -- the photovoltaic industry already has created more jobs than coal mining even though at present it produces much less power. Shelley Schlender interviews Bill Hoch of Montana State University about why leaves turn colors in the fall.  Bill punches some holes in the conventional wisdom on the topic and notes that the color change is a critical step in the trees retaining important nutrients.

On today's pledge drive show we played excerpts from an interview with evolutionary biologist and author Richard Dawkins about his new book, The Magic of Reality: How We Know What's Really True. The book was also featured as a promotional gift for listeners who chose to support KGNU, the independent community radio station that makes shows like How On Earth possible. We now bring you an extended version of that interview. The Magic of Reality is something of a departure for Dawkins. It's a science book, of course, but aimed at an adolescent readership—though certainly adults will enjoy it too. Essentially, the book is about how human beings understand the world, and what we do and do not know. While examining a dozen seemingly simple questions (What is a rainbow? Why are there so many different kinds of animals?) Dawkins explores both human cultural history—how various cultures have used religious stories and mythmaking to explain the world—and the scientific method—how observation and experimentation can s

Nature means something different to everyone. It’s a towering old-growth redwood forest to some.  Deep silent canyons to others. And urban community gardens to others. Defining what is “pristine nature” is even more dicey. Just ask conservation biologists trying to figure out the best ways to preserve ecosystems and their flora and fauna. Co-host Susan Moran interviews Emma Marris, whose new book called “Rambunctious Garden: Saving Nature in a Post-wild World” sheds light on how notions of wilderness preservation are evolving to accommodate the ever-changing natural world, and our own role in it. Tom McKinnon interviews Jeff Bisberg of Albeo Technologies about the new lighting revolution in solid-state LEDs.

  October is Wildfire Awareness Month, so on today's show we look back at the Fourmile Canyon wildfire and hear from local researchers about some of the scientific opportunities that the fire afforded over the last year. Jim Roberts, an atmospheric chemist at the National Oceanic and Atmospheric Administration, tells us about some of the unexpected compounds that have recently been found in the smoke of wildfires. And Deborah Martin, a hydrologist with the U.S. Geological Survey, describes how post-fire runoff from rainstorms affects the forest landscape.

We explore the world microbes, and how they’re everywhere, and how the University of Colorado at Boulder has scientists such as Noah Fierer who are trying to track all those microbes down and figure out which ones help us and which ones don’t, and how they interact.  These scientists have studied the microbes on a human hand, the microbes in the air from dog feces, and they're lastest project is known as Miasma.  That stands for Mapping and Integrated Analysis of Microbes in the Atmosphere.

Feature #1: If you live on the Front Range, or just about anywhere else in Colorado, you don’t have to go far to notice huge swaths of rusty brown that have replaced green conifer forests. By now, many people are familiar at least with the devastating effects of the mountain pine beetle. But far fewer may understand just how these voracious insects actually make their living, or that this epidemic -- and its causes and triggers -- are far more nuanced, and controversial, than meets the eye.  How On Earth co-host Susan Moran talks with Canadian journalist Andrew Nikiforuk about the beetles that have been gorging with impunity on lodgepole pine, spruce and other forests from British Columbia down nearly to Mexico. His new book is called The Empire of the Beetle: How Human Folly and a Tiny Bug Are Killing North America’s Great Forests.Previously, he wrote a best-selling book called Tar Sands. Feature #2:  Sharks have a special place in the human psyche.  Perhaps it is a combination of the mystery of the depth
