Climate engineering // Jamie Williams
01/05/2012 Duración: 25minJamie Williams (start time 5:40). Today on How On Earth we speak with Jamie Williams about land conservation. It’s safe to say that Williams should take credit for large swaths of land in the West that have been preserved as wilderness. He has served as The Nature Conservancy’s director of landscape conservation for North America as part of a 20-year career at the organization. During that time he helped forge unlikely partnerships between ranchers, other landowners and environmentalists. And he led major efforts to garner funding in Congress for conservation, including the largest conservation purchase of private land ever – of 500 square miles of forest in northwest Montana. Williams helped develop the large landscape focus within the Obama administration’s America’s Great Outdoors Initiative, which aims to connect especially young kids to the outdoors. Today, Williams takes the helm of another major conservation organization, the Wilderness Society. Climate engineering (start time 18:12). Geoengineeri

Ron Krauss: Saturated Fat and Red Meat? It Depends
24/04/2012 Duración: 24minWe look at the health effects of saturated fat and red meat with one of the world's leading scientists in the field - Ron Krauss. His recent studies show that replacing saturated fat with carbohydrates INCREASES heart disease risk. But combining high saturated fat with moderate carbs and then adding red meat -- think cheeseburger on a bun -- is yet another story. For the extended version, go here.

Communicating with dolphins
18/04/2012 Duración: 25minDolphins are intelligent and communicative creatures within their own species and with the other animals native to their waters. Still, a hundred million years of evolutionary history and pressures imposed by radically different environments separate dolphins and humans. Can that enormous chasm be crossed? Can we have a conversation with an alien, a different and intelligent species? Twenty-seven years ago, Dr. Denise Herzing first slipped into the warm and clear Bahaman waters in a quest to answer those questions. And every spring since then, she has gathered the crew, the equipment, the money, the courage and the patience to return to work cooperatively with them, unfettered in the wild. Dr. Herzing believes that first we have to understand dolphin society and give them the freedom to choose to communicate with us. This week on How On Earth, Jim Pullen talks with Dr. Herzing about how she communicates with Atlantic Spotted dolphins (start at 6:48). Hosts: Breanna Draxler and Beth Bartel Producer: Jim Pulle

Kinetic Sculptures Refocus the Human Perspective
10/04/2012 Duración: 23minJeff Lieberman is a jack of all science trades, and many non-science trades too, actually. He is a mechanical engineer, a design consultant, a photographer, composer and kinetic sculptor. He hosts the Discovery Channel’s “Time Warp” TV show, has performed at Carnegie Hall, and gave a TedX talk at Cambridge. But the common thread that runs through Lieberman’s various endeavors is his use of technology to elicit a sense of wonder. His science/art combination challenges and shifts human perspectives on the universe (start time 6:05).

Bees and Pesticides // Radiometers and Weather
03/04/2012 Duración: 24minBees and Pesticides (start at 6:40). Two studies published last week in the journal Science (here and here) make a strong case for beekeepers who worry that a new class of pesticides called “neonicotinoids” hurts honeybees and bumblebees. In recent years, honeybee populations have rapidly declined, in part due to a phenomenon known as Colony Collapse Disorder. Bumblebee populations have been suffering as well. Researchers have proposed many causes for these declines, including pesticides, but it’s been unclear exactly how pesticides cause damage. Both of the new studies looked at the effects of neonicotinoid insecticides, which were introduced in the early 1990s and have now become one of the most widely used crop pesticides in the world. One study, from the United Kingdom, shows that the pesticides reduce a bee's ability to store enough food and to produce new queens. In a second study, French researchers tied tiny radios to honeybees then exposed them to low levels of the pesticides; a high number of the

Pesticides, Bees and Niwot Honey Farm’s Tom Theobald [extended version]
30/03/2012 Duración: 31minThis is an extended interview with Niwot Beekeeper Tom Theobald about three new studies that have recently been published regarding the ways that neonicotinoids harm bees. The studies include one from Purdue, and two from Europe, and all three indicate that these new pesticides are causing more harm to bees than previously thought.

The Science of Habit Formation
28/03/2012 Duración: 25minThe Power of Habit: If you’re like most of us you’ve tried over and over again to break a bad habit -- be it procrastinating, gorging on chocolate chip cookies every night, or watching TV rather than exercising. And you know how hard it is to “kick” bad habits. This week on How On Earth we offer one full-length feature (start at 7:57). Co-host Susan Moran interviews New York Times reporter Charles Duhigg, author of a new book titled The Power of Habit: Why We Do What We Do In Life and Business. Duhigg sheds light on why our brains form habits, how they serve (or don't) individuals, as well as companies and societies, and how we can turn bad habits into positive ones once we understand what scientists call the habit "loop." You can also hear an extended version of that interview by clicking here.

The Accelerating Expansion of The Universe // Pine Bark Beetles
20/03/2012 Duración: 24minThe Accelerating Expansion of The Universe (start at 5:11). Have you ever had the feeling that things are moving faster and faster these days? Well, maybe it's not your imagination. Proof that the universe is not just expanding but is accelerating garnered a Nobel Prize last year. To help explain what's going on, we talk to Dr. Adam Riess, a professor of physics and astronomy at the Johns Hopkins University and is a scientist at the Space Telescope Science Institute in Baltimore. When he was a research fellow at the University of California, Berkeley, from 1996 to 1999, Dr. Riess and his colleagues conducted the research that was to win him a share of the 2011 Nobel Prize in physics. The citation for the prize stated it was: “for the discovery of the accelerating expansion of the Universe through observations of distant supernovae.” In today's show, Dr. Riess translates what that means and the implications about the ultimate fate of the universe.

Fukushima Anniversary: global impacts one year later
14/03/2012 Duración: 25minFukushima's impacts a year later: In today's show we offer a full-length feature (start at 4:57) to mark the one-year anniversary of the Fukushima Dai-ichi nuclear power plant disaster -- the worse nuclear meltdown since Chernobyl in 1986. We explore the longer-term impacts on public health, the environment, and the nuclear power industry, both in Japan and in the U.S., Europe and elsewhere. Co-host Susan Moran interviews two nuclear experts: Jeff King, the interim director of the Nuclear Science and Engineering Program at the Colorado School of Mines; and Len Ackland, co-director of the Center for Environmental Journalism at the University of Colorado, Boulder. He is also author of “Making a Real Killing: Rocky Flats and the Nuclear West.” (King and Ackland also joined us on March 22, last year.)

The Wandering Gene and the Indian Princess
06/03/2012 Duración: 26minFor our annual Spring Pledge Drive, we feature a book about race, religion and DNA. The book is The Wandering Gene and the Indian Princess, by Jeff Wheelwright. It's a story about a beautiful young, Hispano woman in the San Luis Valley of Colorado who one day finds a pea-sized lump in her breast. Her name is Shonnie Medina. She is both Spanish and Native American - and the Spanish side of her family has been in the San Luis Valley for many centuries, farming, ranching, for the most part devout Catholics, often proud of their Catholic Spanish heritage. We learn that Shonnie is a carrier of a potentially deadly condition, because her DNA includes “the breast cancer gene" that increases the risk of breast cancer, in some cases, by 80%, while also increasing the risk of other cancers, including some in men. It’s a mutation that is over a thousand years old, and surprisingly, the version of this mutation that Shonnie carries is sometimes known as a "Jewish" cancer. For more, here’s Shelley talking with The

Fukushima Cleanup // Space Debris
29/02/2012 Duración: 23minToday, Feb. 28, we feature two interviews. Fukashima Cleanup (start at 7:23). A daunting and ongoing cleanup task is that of removing radioactively contaminated material from Japan's Fukushima Daiichi nuclear power plant. The plant suffered a meltdown in the wake of a massive earthquake and subsequent tsunami on March 11, 2011. The tsunami swallowed whole towns and killed more than 20,000 people. How On Earth Executive Producer Shelley Schlender interviews Steve Rima, vice president of Radiological Services and Engineering at AMEC, in Grand Junction, Colorado. AMEC is assisting with radiation cleanup in the 500-square-mile Fukushima evacuation area. (Scroll down to previous post to hear extended version of the interview.) Space Debris (start at 14:10). You thought cleaning your room was a chore. Imagine the problem if your room was the size of, say, the space around Earth where real, full-sized rockets and satellites are in orbit. Who is going to clean all that up? Or is it even a problem? How On E

Fukushima Cleanup [extended version]
28/02/2012 Duración: 20minThis is an extended version of an interview the KGNU Science show, How on Earth broadcast on February 28th, 2012 about radiation clean-up efforts for Japan's Fukushima Nuclear Power plant. This interview features Steve Rima. He’s Vice President of Radiological Services and Engineering at AMEC, in Grand Junction, Colorado. He’s been working in Japan on offsite cleanup of 500 square miles near Fukushima that were evacuated and must be cleaned up before residents can move back. Rima’s company is assisting with that cleanup. He says that he has been there several times in the last few months. In this interview, Rima speaks with How on Earth's Shelley Schlender, via Skype.

Leaky Natural Gas Wells // Measuring Glaciers and Ice Caps
21/02/2012 Duración: 23minLeaky Natural Gas Wells (start time 6:22). We speak with Greg Frost, a scientist from the University of Colorado at Boulder and the National Oceanic and Atmospheric Administration (NOAA), about a new study, which is being published by the Journal of Geophysical Research. The study indicates that natural gas drilling creates higher amounts of methane leakage into the atmosphere than previous estimates had indicated. Methane is a potent greenhouse gas, and unless this problem of leakage is solved, there is concern that drilling for natural gas might cause higher levels of greenhouse gases in the atmosphere than burning coal. We also offer an extended version of this interview. Recent Contributions of Glaciers and Ice Caps to Sea Level Rise (start time 14:25). Scientists at CU's Institute of Arctic and Alpine Research now have used eight years worth of satellite data to a clearer picture of how climate change is impacting the cryosphere, or ice-covered parts of the planet. (See animations here.) Knowin

Leaky Natural Gas Wells [extended version]
21/02/2012 Duración: 27minThis is an extended version of the KGNU Science Show, How on Earth. It features Greg Frost, a scientist with the University of Colorado at Boulder and with NOAA, the National Oceanic and Atmospheric Administration. He's on the team led by Gabrielle Petron which has been studying leaks from natural gas production. In this extended interview, Greg tells us about natural gas wells in Colorado that are leaking twice as much methane and benzene into the atmosphere as official estimates have indicated. Methane is a potent greenhouse gas. Benzene is a carcinogen. Let’s listen in now, as Greg Frost tells How on Earth's Shelley Schlender what their study of leaking methane from gas wells found.

Boulder Robotics // Compassion
14/02/2012 Duración: 23minBoulder is for Robotics (start time 4:00). "It starts really with the fact that a lot of robotics materials, sensors and manufacturing are here in Colorado." Boulder as a hub for robotics? You bet. KGNU's Tom McKinnon reports from the first Boulder is for Robotics meetup, which drew over 100 participants. Learn about some local projects, from robots for agriculture to robots for kids. The Neurology of Compassion (start time 12:50). "Someone on the street asks you for money. Do you give or not? What drives that decision?" Researchers Jessica Andrews-Hanna and Yoni Ashar from University of Colorado's Cognitive and Affective Neuroscience Lab talk to us about the causes and effects of compassion. The first of their studies on compassion looks at charitable giving. What determines whether a person will decide to donate part of their earnings? They also talk to us about their current study, which involves using brain scans to evaluate the effect of compassion meditation. Hosts: Tom McKinnon & Beth Bartel P

Snowshoe Hare // Cubelets Robotics
07/02/2012 Duración: 24minSnowshoe Hare Faces Uncertain Future (start time 6:35). They don’t get much cuter than bunnies. One of the cutest of them all is the snowshoe hare. It’s elusive, and well camouflaged, so you may well never have seen one. To survive, these hares change their coats with the seasons – white in the snowy winter and rusty brown in the summer. So now, some hares’ fur turns white before the snow covers the ground. Think what it’d be like to be naked in public, an easy meal for eagles and other predators. Whether these fragile hares can evolve and adapt to their changing homes fast enough is a question some biologists are studying hard. Hillary Rosner, a local science journalist and author, wrote about the plight of the snowshoe hare in the current issue of High Country News and now talks with How on Earth's Susan Moran. Cubelets Robotics (start time 15:00) is an award-winning modular robotics kit created and made in Boulder. The concept is simple: you take these magnetic blocks and snap them together to make

Algae oil omega-3 // Little Ice Age
01/02/2012 Duración: 23minAlgae Oil Omega-3 (start time 5:28). Omega-3 dietary supplements are all the rage. Many studies claim that this family of fatty acids benefits your brain, heart and vision, among other things. A non-fish source that already is infused in milk and other foods we consume is oil derived from marine algae. Cohost Susan Moran interviews Dr. Bill Barclay, a microbial ecologist who manages the Boulder division of Martek Biosciences (now DSM). He talks about how he discovered how to produce DHA omega-3 oils from microalgae, and how they can boost our health in an environmentally sustainable way (or at least free of concern about overfishing). Little Ice Age (start time 15:25). Shortly after the Middle Ages, something strange happened. Suddenly, the entire world got a little cooler. And then it hung on. The cooling lasted over 500 years, all the way to the 1800s. Those five cool centuries are known as the Little Ice Age. How it happened has been a mystery that modern climate scientists have worked hard to figu
