Kgnu - How On Earth

Today, Dec. 8, we offer the following feature: Changing Climate, Changing Policy (start time: 7:06): As political leaders are still hammering out an accord at the UN Climate Summit, or COP21, in Paris, to rein in global warming, today we discuss the underlying scientific facts about climate change, and the policy promises and challenges for our future. Hosts Susan Moran and Daniel Glick interview two Colorado scientists at the intersection of science and policy. Dr. Waleed Abdalati is a geoscientist and director of the Cooperative Institute for Research in Environmental Sciences (CIRES), a partnership between the University of Colorado-Boulder and the National Oceanic and Atmospheric Administration. Dr. Lisa Dilling is an associate professor of environmental studies, also at CIRES, who brings expertise in science policy related to climate issues. She directs The Western Water Assessment, a NOAA program that provides information for policy makers throughout the Intermountain West about the region’s vuln

What is graduate school and how does it differ from the undergraduate experience?  What drives people to go through another 4...5...6...or more years of school? Today's show features some people who might be able to tell us about the grad school experience in the sciences.  We have three grad students from the University of Colorado at Boulder: * Joe Villanueva in the Molecular Cellular and Developmental Biology department. * Annie Miller, in the Integrative Physiology department. * Marcus Piquette, in the Astrophysical and Planetary Science department. Each of them works in a lab with an advisor and is doing projects that will eventually lead to a thesis and getting a PhD, and they talk about what they do and what grad school is like.

Today we had a terrific show with two local guests.  First, Sarah McQuate, Post-Doc at the University of Colorado joins us to talk about CUCafe, a student run group committed to creating dialogues and safe spaces for underrepresented student on campus.  We talk about their role in the most recent Inclusion and Diversity Summit on campus along with their on-going efforts and events. cucafeseminar.wordpress.com   Next, Julie Rehmeyer, a award-winning science tells us about her experience as a math graduate student at MIT and her investigative research into Chronic Fatigue Syndrome.  These two stories form interesting connections as we discuss the meaning of intuition; a skill that is acknowledge as powerful in the mathematics community but not necessarily cultivated or nourished.  Additionally, Julie finds resilient solutions using her analytical and intuitive skills when enduring a incapacitating experience with Chronic Fatigue Syndrome, treatment for which is scarce and poorly understood in the scientific

In today's show we offer the following feature: The Horse (starts at 6:25)  Next to our connection with dogs and cats, perhaps the deepest bond humans have developed over time is with horses.  In fact, hands down, the horse has done more for us than either of those furry pets. That is, horses lie at the very foundation of our human civilization. Modern humans evolved with the horse.  A new book explores the deep history of this deep bond, and the far deeper history of the horse itself and its evolutionary biology over millennia. Ever wonder why  horses have such big teeth—unlike other hoofed mammals?  The book, which spans the globe as well as the horse’s anatomy, is called The Horse: The Epic History of Our Noble Companion.   Its author, journalist Wendy Williams joins host Susan Moran to talk about these beautiful creatures. Williams will speak on Nov. 16 at the Denver Museum of Nature and Science. Hosts: Susan Moran, Kendra Krueger Producer: Joel Parker Engineer: Kendra Krueger Executive Producer: Beth Be

Mighty Microbes (start time: 5:45): Microbes – fungi and bacteria and probably viruses -- are essential to life on Earth. They’re found in soil and water and inside the human gut. There’s a lot happening these days in microbiology, as scientists try to better understand what role these invisible powerhouses play in our health and that of the planet. Amy Sheflin, a PhD candidate at Colorado State University in the department of Food Science and Human Nutrition, speaks with host Susan Moran about her and others' research into how microbial communities an enhance the health of our human gut, soils and crops.

Rock Arch Stability (Starts 5:24) How on Earth's Daniel Strain  talks to Jeffrey Moore, a geologist who studies the West’s iconic rock arches — and watches them for signs that they’re about to collapse.   Neonicotinoids and Silent Spring - (Starts 15:33) We share a story from H2O radio warning about a pesticide that’s linked to the collapse of honeybee colonies, and growing concerns that it’s dangerous for other forms of life, it's persistent in the environment and might bring about a new Silent Spring.  This information will be part of this week's Western Apicultural Society conference in Boulder.   Hosts: Shelley Schlender and Daniel Strain Producer: Shelley Schlender Engineer: Shelley Schlender Executive Producer: Susan Moran Listen to the show:

This week on How on Earth, we speak with Dr Paula Hoffman, a neuropharmacologist - she's scientist who studies what drugs do in the brain- who works on the genetics of alcohol and other drugs of abuse. Paula reviews the action of alcohol on different neurotransmitter systems of the brain then describes some of the genetic issues which predispose people to risk for becoming alcoholics. Finally she talks about research done in her lab which has resulted in preliminary understanding of genetic networks involved.

Quantum Biology: Life on the Edge What do Enzymes and photosynthesis have in common?  Both are biological process that happen to rely on quantum mechanisims.  That's right, particles tunnling through walls, shifting between particle and wave states: The weirdness of the quantum world isn't as isolated as we once thought. This past summer Life on The Edge, a book about the frontiers of quantum biology was released to US audiences. How on Earth corespondent Kendra Krueger caught up with one of the authors Johnjoe Mcfadden to talk more about the book and the weird science of quantum biology.   Science and Art with Monica Aiello Monica Aiello is a visual artist who has worked with numerous scientific agencies to re-incorporate art into science.  She and her husband work closely with earth scientists and NASA mission scientists, including scientists involved in NASA’s Voyager, Galileo, Messenger and Magellan missions. Their collaboration with scientists doesn’t just inform their art work, but is also part of t

Habitat Exchanges (starts at 3:00):  The greater sage grouse is ruffling feathers all the way to Washington.  September 30th is the deadline for the US Fish & Wildlife Service to determine whether to list the grouse under the Endangered Species Act. More than a third of the sage grouse’s shrinking range is on private land. Which is why many ranchers, oil and gas developers and other landowners have been scrambling to keep the grouse from getting listed. Listing would mean tighter restrictions on land use. The Environmental Defense Fund (EDF) is one of several environmental organizations that are trying to help come up with ways to preserve the sage grouse and its habitat without cramping the livelihood of ranchers and other land owners. One of the newest voluntary tools is what is called a habitat exchange, a marketplace with buyers and sellers of conservation credits.  How On Earth's Susan Moran talks with Eric Holst, associate vice president of EDF’s working lands program, about these exchanges.

Fingerprint Hand Gun.  (starts at 5:45) How on Earth's Shelley Schlender talks with Boulder teen scientist Kai Kloepfer, who is creating a “Smart Gun” that won him first prize in engineering at the INTEL international science fair and a $50,000 grant from the Smart Tech Challenges Foundation.  Kloepfer's goal is to prevent accidental shootings of children.  His gun fires only when the user's fingerprint is authorized. High Altitude Observatory.  (starts at 11:35) Director Scott McIntosh talks with How on Earth's Joel Parker about the observatory and its 75th year celebrations.       Hosts: Joel Parker, Kendra Krueger Producer: Shelley Schlender Engineer: Shelley Schlender Headline Contributors: Shelley Schlender Executive Producer: Susan Moran Listen to the show:

Science and Politics of Mining (start time: 6:49)  On August 5 an inactive mine named Gold King, which had been leaking toxins for years, spewed more than 3 million gallons of toxic sludge into a creek that feeds into the Animus River in southwest Colorado. Its neon orange path of wastewater was shocking. But also shocking is the long history of acid mine drainage pollution and the lax regulations that allow mining companies to basically walk away from their disasters. Dr. Mark Williams, a professor of geography at CU Boulder, and an expert in mountain hydrology and hydrochemistry., has worked on remediation of several mines in the state. He speaks with How On Earth host Susan Moran about the anatomy of mines, how this disaster happened, what it suggests about the many other precarious mines in the state, and what should be done to prevent such disasters from happening.

When it comes to reducing greenhouses gases, every little bit helps, and that includes managing the greenhouse gases produced by how we grow our food.  Raising livestock and growing crops both generate greenhouse gases, and to gauge their impact, a new study takes the long range view.  The results were published in a paper: "Measuring and mitigating agricultural greenhouse gas production in the U.S. Great Plains, 1870-2000" in the Proceedings of the National Academy of Sciences.  It analyzes 100 years of agricultural production, and it takes this look at farming close to home - it focuses on the bread basket of the United States - the Great Plains, which includes eastern Colorado.  Here to tell us more are scientists Myron Guttman (University of Colorado) and Bill Parton (Colorado State University) Hosts: Shelley Schlender, Kendra Krueger Producer and Engineer: Joel Parker Executive Producer: Susan Moran Headline contributions: Beth Bennett, Kendra Krueger, Joel Parker Listen to the show:

Real Food (start time 4:20): What we eat , and how we eat, is inextricably connected to our own health as well as the health of the planet.  Every decision we make—whether to bake a chocolate cake or buy it from Safeway or at a Farmer’s Market—is full of nuances and even contradictions. Megan Kimble is a writer who became obsessed with wondering how she could make a difference in the world by examining her eating habits. Her just-published book, called Unprocessed: My City-Dwelling Year of Reclaiming Real Food, is her personal journey into the scientific, public health, environmental and political issues related to food. Kimble will  speak tonight at the Boulder Book Store, at 7:30, and tomorrow night, July 30, at Tattered Cover in Denver, at 7:00 p.m. The Buzz About Bees (start time 13:49): Across the United States, buzzing pollinators are key to the growth of countless flowering plants. But many bee species are also disappearing nationwide, due to pesticide use, habitat loss, and other threats.  Dr. Sam
