KGNU - How On Earth

human gut microbes Our Microbes, Ourselves, Dec. 31, 2015: Roughly one hundred trillion bacteria are living, and gorging, in our gut–all the more so during the indulgent holidays. Microbes influence our health and well-being, by affecting our gut directly, as well as the crops we eat and the soils in which we grow crops. These microbial communities  – called the gut microbiome — have been linked to many disorders, including obesity, inflammatory bowel disease, diabetes, cancer, immune disorders, and even mental illness. We are just at the dawn of a new era of microbial treatments for many illnesses. After a recent How On Earth show generated so much interest, we decided to bring our guest, Amy Sheflin, back for an hour-long call-in show on A Public Affair on KGNU. Amy is a doctoral student at Colorado State University in food science and human nutrition. She studies how the food we eat alters the microbial communities in our gut, and how those microbes in our bodies influence our overall health. For more info on the gut microbiome, check out Amy’s favorite books on the topic: The Good Gut, by Justin and Erica Sonnenburg; and The Inside Tract, by Gerard Mullins. Also check out the American Gut Project. Host: Susan Moran Engineer: Maeve Conran Click here to listen to the show:

Hunter Lovins – Natural Capitalism Solutions Hunter Lovins – Regenerative Economics (Starts 2:42) One of the world’s leading voices for the environment is urging the world to work for even more than a sustainable economy.  She says it’s time for a regenerative economy.  That’s the message from Boulder County resident, Hunter Lovins.  Lovins heads up Natural Capitalism Solutions, and she’s a sought after speaker around the world, as well as here in Colorado.  To give you an idea about what the vision of Lovins for a regenerative economy, here is an excerpt from a recent talk about the Future of Humanity.  This talk was recorded in Boulder as part of the Colorado Chautauqua Events series, in conjunction with the Boulder City Club. For the extended version of this talk, go here. Host: Kendra Krueger Producer: Shelley Schlender Engineer: Kendra Krueger Executive Producer: Beth Bennett Listen to the show:

Climate Change and Cities (starts at 5:05)  Sea level rise, severe storms, heat waves – these are just a few of the challenges cities might be facing as the climate changes in the next few decades.  So how should they adapt to cope with such events? And with urban developments being one of the largest contributors to greenhouse gas emissions, what can they do to mitigate their impact? These are questions that the Urban Climate Change Research Network has set out to address in its Second Assessment Report on Climate Change and Cities.  The report gives the expected climate projections for 100 cities along with guidance on increasing resilience and reducing impact.  The Network released its summary for city leaders at the Paris talks only three weeks ago, and Boulder’s Paty Romero Lankao was there to promote the report — she was a co-editor of the report and coordinating lead author of the chapter on governance. Dr. Lankao is a research scientist at the National Center for Atmospheric Research who investigates the interactions between urban development and global environmental change, and in our show she talks with us about the outlook for cities and the report.

Today, Dec. 8, we offer the following feature: Waleed Abdalati, photo credit David Oonk/CIRES 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. Lisa Dilling, photo credit Casey A. Cass/University of Colorado 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 vulnerabilities to climate change impacts. Contributing host Daniel Glick was an editor of the 2014 National Climate Assessment, and his team has produced videos on the immediate and human impacts of climate change.

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 community. HERE is here latest article on the research of CFS Hosts: Susan Moran, Kendra Krueger Producer: Kendra KRueger Engineer: Kendra Krueger Executive Producer: Beth Bennett Additional Contributions: Joel Parker Listen Here:

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.

Amy Sheflin Photo credit: Carolyn Hoagland 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.

The teenaged brain is wired differently than the adult. Brains (starts at 4:35) This week on How on Earth we interview Professor Marie Banich, from the University of Colorado here in Boulder. Dr Banich uses cutting edge methodologies, particularly structural and functional MRI, to examine the role of the prefrontal cortex, as well as other brain regions, in executive function. Today she tells us about work that was recently funded by NIH to characterize how these systems change over the course of development.
