Kgnu - How On Earth

  Today's special edition of How on Earth, brought to you in conjunction with this week's Conference on World Affairs is a conversation on Biomimicy as a new lens to view science and technology with Margo Farnsworth.  Margo has coached two Top Twelve graduate teams for the International Student Biomimicry Challenge and currently serves as a Biomimicry Institute education fellow. She is also on the board of both the Missouri Prairie Foundation and South Carolina’s Experience Green. She has worked as a park ranger, science teacher, and mammalogist. With degrees in science education and parks administration, her professional accomplishments include research in environmental education, qualitative mammal studies, and involvement in numerous local and state environmental boards and committees. Farnsworth has written pieces for the Center for Humans and Nature as well as Treehugger, and has two biomimicry book projects pending.  She joins us live for an in-depth talk about how Biomimicry has the potential for chan

Island on Fire (04:45): In 1783, a crack opened up in the Earth, began to spew out lava and ash and poisonous gases, and didn’t stop for eight months. The volcano was Laki, one of many volcanoes in Iceland, and the effects of the eruption went global. Laki’s story is one of geology, chemistry, atmospheric science, and biology. Co-host Beth Bartel talks with long-time science writers and co-authors Alexandra Witze and Jeff Kanipe about what we’ve learned from Laki and how we can apply the lessons of Laki today. For more on the book, check out the Island on Fire website.

Climate Scientists (starts at 1:00): Climate scientists (scientists in general)  tend to steer clear of speaking out as activists about concerns that are politically volatile.  But that’s changing. Many climate scientists are stepping out of their research comfort zone to offer personal stories of why they care and what we all can do about the crisis.  A group of scientists launched a video campaign last week. It’s called More Than Scientists.  We speak with Dr. Josh Lawler (University of Washington), who one of the founders of the campaign. Polar Bears (starts at 6:30):  It is well known that, right now, life for polar bears looks bleak.  Warming temperatures mean the season for sea ice cover in the Arctic has become shorter and shorter. As sea ice provides a home and hunting ground for polar bears, both the number of bears and their health has suffered.  There is even talk of them becoming extinct.  But is this something that we should worry about in Colorado and other non-arctic regions around the world?

Nematode worms for studying Alzheimer's (start time 4:57). Beth Bennett interviews Dr Chris Link from CU Boulder on his research into the genetic basis of Alzheimer's Disease, ALS, and other neurodegenerative disorders.

On today's spring pledge-drive show we offer segments of two feature interviews. See extended versions also below. Both books are available to those who pledge at least $60 to KGNU. Call 303.449.4885 today. Rust: The Longest War (start time: 4:25) It is arguably the most destructive natural disaster in the modern world. And it's the topic of local journalist Jonathan Waldman's debut book, which has just been published. It’s called Rust: The Longest War. Jonathan talks with How On Earth host Susan Moran about the book, which included fascinating tales of the "smart pig" that inspects the Alaska pipeline, as well as Ball Corp’s Can School in Golden, Colo. Catch Jonathan tonight  7:30 at the Boulder Book Store. The Moral Arc (start time: 13:21) Author and renowned skeptic Michael Shermer talks with How On Earth contributor Shelley Schlender about his The Moral Arc: How Science and Reason Lead Humanity toward Truth, Justice, and Freedom. The book addresses a wide range of modern issues, including just how scien

ATLAS Institute Today we are joined in the studio with Mark Gross of the Alliance for Technology, Learning and Society institute at CU and Alicia Gibb Director of The Blow Things Up Lab, one of the spaces part of the ATLAS department. ATLAS was formed in 1997 as a university wide initiative to integrate information technology into social endeavour. ATLAS events: http://atlas.colorado.edu/wordpress/?page_id=99 BTU Lab: http://www.btulab.com/about Firefighters and Climate Change Snowy frigid weather here in February may put wildfires way on the back burner for many of us here in Colorado. But as fire managers have been telling us, wildfire season has become a year-round phenomenon. In the last decade or so wildfires have been getting more intense, and more dangerous, and more frequent.  No one knows this better than the firefighters themselves. Climate change—making the region hotter and drier—has a lot to do with it. But so does fire management—namely, fire suppression over recent decades. And humans living

We speak with Eugene Harris, Professor in the Department of Biological Sciences and Geology at Queensborough Community College - part of  the City University of New York - about his new book,  Ancestors in Our Genome. In this feature, we discussed the methods used by molecular anthropologists to determine human evolution from our primate ancestors and several fascinating examples of the application of these techniques, including a discussion of the rise of lactose digestion in northern Europeans.

War of the Whales: A True Story (starts at 3:35): In the early hours of March 15th, of the year 2000, a Cuvier beaked whale washed ashore a mere 100 feet from Ken Balcomb’s house on the island of Abaco in the Bahamas. It was, for the whale, a fortuitous coincidence: Balcomb was a marine mammal researcher who was uniquely placed to rescue the creature. But that day 17 more whales of various species washed up on nearby islands and some of them weren’t quite so fortunate. The event was the largest mass stranding in recent history but what might have caused it was a total mystery. To Balcomb, it was a mystery that cried out for a solution. So begins the book “War of the Whales: A true story.” It’s a book that has been described by critics as a tense, page turning eco-thriller, even though it is a work of non-fiction. How On Earth's Jane Palmer talks with author Joshua Horwitz about what happened after Ken Balcomb’s discovery, and the attempts to solve the mystery. Hosts: Beth Bartel, Jane Palmer Producer: Beth

Arctic Dispatch (starts at 2:18): There is no question that the Arctic is thawing faster than anywhere on the planet, except the western Antarctic Peninsula. But there are still so many unknowns regarding how things are actually changing in different places, and to what effect. How On Earth's Susan Moran recently attended the Arctic Frontiers conference in Tromso, Norway. Among the scientists who discussed research on how the receding and thinning ice in the Arctic will likely affect different species was  George Hunt, a research professor of biology at the University of Washington. Aili Keskitalo, an indigenous Sami from Finnmark, Norway and president of the Sami Parliament, discussed how energy projects, including windmill parks, are negatively affecting reindeer and Sami culture. Hunt and Keskitalo discussed these issues with Moran. Wind forecasting (starts at 10:40): The wind industry in the U.S. faces several hurdles, including a technical one: discovering how the wind is going to blow near the mounta

We talk with astronomer Travis Metcalfe about finding the oldest known planetary system in the Galaxy, and what it means about the formation of planets, the possibilities of extraterrestrial life, and how does one actually find planets around other stars? Headlines include switches in the man-made biological organisms that could possibly be used for bioterrorism, and the finding that chronic malaria infection in migrant great reed warblers  damages telomeres, shortening life in both the adult bird and its offspring.

The Science of Moonshine  (starts 3:55) We talk with a Boulder scientist who has a home still for making high-proof brandy from backyard apples.  It's illegal to make your own liquor, even if you only sip it with friends and never sell it.  So our moonshiner remains anonymous.     Parkinson's Network Exercise Class (starts 7:35) Gary Sobel leads an exercise class for people with Parkinson's Disease.  He talks about his own experience with exercise, and movement disorder specialist Heather Ene, MD, PMR/Neurology, shares the reasons physicians have moved from asking Parkinson's patients to avoid exercise, to encouraging exercise. Hosts: Kendra Krueger, Beth Bennett Producer, Engineer: Shelley Schlender Executive Producer: Kendra Krueger Listen to the show:

The rightful place of science (starts at 6:22): In 2014, the world certainly saw more than a few costly weather disasters.  Flooding in India and Pakistan in September killed more than 600 people and resulted in economic losses of more than $18 billion.  Super Typhoon Rammasum, which hit the Philippines, China and Vietnam in July caused more than 200 deaths and losses of $6.5 billion. And, closer to home, in August, rainfall and flooding in Detroit, Baltimore and Long Island damaged homes and cities leading to economic losses of about $2 billion. At the same time, the United Nations Weather Agency states that 2014 was the warmest year on record. So, the question is: Are these natural disasters related to the warming climate?  And are natural disasters becoming more costly because of climate change? These are questions that Roger Pielke Jr., an environmental sciences professor at the University of Colorado, addresses in his new book “The Rightful Place of Science: Disasters and Climate Change.”  He talks with

On today's show we offer three feature interviews, including a short opening interview. Alcohol and weight gain (starts at 3:34): Science journalist Jill Adams shares the latest science on the connection between alcohol and weight gain. The science is murky, as she states in her recent column in the Washington Post.   Climate Clues in Coral (starts at 9:02): Despite certain appearances and rumors to the contrary, global warming has not been on holiday for the past decade. But increases in temperature at the Earth’s surface have slowed down, prompting scientists to work hard to figure out why. It seems that a lot of heat that has been building up in our planet’s climate system due to greenhouse gas emissions has winded up deep in the Pacific Ocean. Why? Diane Thompson, a post-doctoral scientist at NCAR and lead author on a new study, discusses with HOE's Tom Yulsman how a sample of coral from a remote atoll in the tropical Pacific revealed some important answers. Tropic forests love CO2 (starts at 16

"Sugar" in Red Meat - Cancer in Mice? (starts at 6:10) We talk with Ajit Varki, a researcher at the University of California in San Diego whose latest mouse studies  reveal a potential inflammatory compound in red meat -- a "sugar" called sialic acid.  (For more, listen to our extended version of this interview)     Paleo Diet - Avoid Grains and Beans (starts at 9:10) We talk with Colorado State University scientist Loren Cordain, founder of the Paleo Diet movement. He and his colleagues have study humans and the influence of diet. For health and athletic performance, Loren recommends avoiding modern foods that are high in grains, sugar, salt, legumes and additives.  Instead, he says, eat like our paleo ancestors - fruits and vegetables and fats and meat.    (For a fee, you can subscribe to Loren’s latest podcasts at his website.  Fro free, you can listen to older podcasts.  Find out more at thepaleodiet.com. Today's show also includes a look back at some of our favorite science stories from 2014. Host

I’m Shelley Schlender for How on Earth.  Up next is an extended interview with University of California in San Diego scientist Ajit Varki  about his team’s new mouse study that indicates that a “sugar” in red meat, called sialic acid, can trigger inflammation when fed to mice.  This sugar is intriguing because it’s a molecule that two million years ago, our human bodies made on their own.  It differs from the current sialic acid made in our bodies by just one atom of oxygen.  Yet the mouse studies indicate that might be enough to cause an immune system reaction in the lab mice.  More research and human studies will be needed, to determine whether or not a similar reaction occurs in susceptible humans.  Now here’s Ajit Varki.  

Himalayan Glacial Lakes (starts at 5:20) Some scientists conduct their experiments in a laboratory — think clean white walls, artificial lighting, A.C. and a convenient coffee pot not far away. Not so for Ulyana Horodyskyj, a graduate student at the University of Colorado. For the last few years she’s been looking at glaciers and the lakes on top of them in Nepal. Last year she spent a year looking at how pollution affects glaciers high in the Himalayan Mountains. She hoped to set up the ultimate high-altitude laboratory on the oxygen-thin slopes of Mount Everest, but a fatal accident intervened. On this edition of How on Earth, she talks about her latest research, Himalayan glaciers and what it is like to do science at the top of the world.

Weather drones (start time 5:10) Brian Argrow, former professor and Associate Dean of engineering at CU Boulder, joins us in the studio to talk about the recent formation Unmanned Aircraft Systems and Sever Storm Research Group.  The group is a collaboration between the CU Boulder and the University of Nebraska-LIncoln who have been working together since 2006.  The group now consists of a large number of members including local national labs and university groups.  The purpose of their research is to learn more about storm formation in order to improve emergency response time. Dr. Theo Colborn (start time 15:22) Dr. Theo Colborn passed away on Sunday December 15th at the age of 87.  She was a scientists, activist and founder of The Endocrine Disruption Exchange (TEDX).  The exchange served to collect and disseminate scientific evidence on the effects of exposure to low-levels of industrial chemicals.  During this pre-recoreded interview from our colleagues at KVNF Paonia Public Radio, she talks about the

The Yasuni National Park in Ecuador is one of the most biodiverse places on earth, but it is currently at risk from oil development. Some of the park's inhabitants, however, are trying to forge a more sustainable, and less destructive path out of poverty.  These indigenous Kichwa people, who have already been caretakers of the rainforest for hundreds of years, have developed ecotourism in the region, providing all the jobs, schools and healthcare that they need. How did the community find the commitment and tenacity required for such a project? By thinking like Leafcutter ants. To find out about the award winning model of conservation and sustainability H20 Radio’s Frani Halperin and Jamie Sudler visited the region earlier this year and produced the podcast   Want to save the Amazon? Think like an Ant. We play this feature [4:15] on this week's show and afterward [18:30] talk with Frani and Jamie about the project and what Coloradoan's can learn from the Kichwa community's efforts.
