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. Pine Bark Beetles (start at 19:22). The tree-kill

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

Underwater Volcanoes // Sleep
24/01/2012 Duración: 23minUnderwater Volcanoes (start time 5:45). Most of our planet's volcanoes are out of sight, and largely out of mind. Hidden under sometimes thousands of feet of water, volcanoes on the sea floor bubble and boil away without our knowledge and largely without our understanding. We talk with Oregon State University volcanologist Bill Chadwick about some of his research on these buried giants. More information (with photos and videos) are available at NOAA's VENTS Program. Sleep (start time 15:50). As any mother knows, when children get cranky, one of the best solutions is to “go take a nap.” What is less understood is whether or not those naps can be now and then, or whether it’s important to keep them regular. We speak with an expert who has just published a study that looks at the question of napping among preschool children. Her name is Monique LeBourgeois and she’s a professor of Integrative Physiology at the University of Colorado's Sleep and Development Lab. Co-hosts: Joel Parker and Shelley Schlender Cont

Nicotine Patches // Restoring the Desert
10/01/2012 Duración: 24minDo nicotine patches really help you stop smoking? Shelley Schlender interviews a scientist who says they don't. Lois Biener and her colleagues at the University of Massachusetts and Harvard University have done a study that 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. (Extended interview version here). Great plumes of dust rising from the desert forms an iconic image of the West, but much of that dust is a result of humans altering the desert soil structure. Several Boulder scientists are investigating a new technology that may allow us to restore the desert, and sequester large amounts of carbon at the same time. Tom McKinnon interviews Jim Sears, president of A2BE Carbon Capture and Bharath Prithiviraj, a Postdoctoral Research Associate in Chemistry and Biochemistry at the Uni

Nicotine Patches Don’t Work [extended version]
10/01/2012 Duración: 07minThis 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.

Clean Water Struggles // 2011’s Big Sci-Enviro-Tech Stories
27/12/2011 Duración: 23minMining 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

Holiday Sci & Tech Gifts // Eating Your Heart Out?
20/12/2011 Duración: 23minWe 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
