Microbes and Stress Resilience (starts 5:13) If you’re worried that some dirt still clings to your skin under your fingernails after planting or weeding in the garden, fear not. In fact, the more you feel and even breathe its fumes, the better, research suggests. As part of our series called “Our Microbes, Ourselves,” we explore today a newly published study that adds to a growing body of research into the benefits of certain soil and gut microbes on our mental and physical health. Dr. Christopher Lowry, an associate professor of integrative physiology at the University of Colorado-Boulder, discusses with host Susan Moran the study, which he led. It shows that a common soil bacterium called M. vaccae can boost the immune system to help fight stress and inflammation. The research, published last week in the journal Proceedings of the National Academy of Sciences, was conducted on mice, but the health implications for humans are far-reaching.

The Science of Mind Over Body

Cure-US-coverMind+Body Science (start time: 4:52): If you’ve ever struggled  to decide whether to see a Western conventional doctor or an  “alternative” medical practitioner for ailments ranging from a compromised immune system to irritable bowel syndrome, you are aware of a deep divide between the two camps. Dr. Jo Marchant, a British geneticist and science writer, has delved into the science and politics of mind-body connections in her new book. It’s called Cure: A Journey into the Science of Mind Over Body. She discusses this journey with host Susan Moran. (We played snippets from the interview during the recent  pledge-drive show. Thanks to you, listener-members, for your support! And thanks, Crown Publishers, for allowing KGNU to give copies of Cure to those who pledged during the show.

Headlines (0:56 – 4:30) 1) Analyzing the molecular signature from our body’s microbial communities might be used in the future to link suspects to crimes definitively. 2) New research explores whether molecules behave like predatory animals when it comes to foraging for food.

Today’s show offers two features:
High School STEM Stars (start time: 5:00): Developing polymers to reduce waste from biodiesel production. Using 3D printing to design ocean textures, such as fish gills and waves, that blind students can use in textbooks to better understand nature. These are the kind of vexing challenges of seasoned scientists. Well, a select group of high school students here on the Front Range are also diving into this research, through the University of Colorado’s Photo-Origami Research Project. It’s part of the Research Experience and Mentoring (REM) program. Our guests–Lindsey Welch, a sophomore at Centaurus High; and Tyco Mera Evans, a senior at Northglenn High– will give poster presentations at the Emerging Researchers National Conference in STEM, in Washington, D.C.  this week. Joining them in the studio is Kathryn Penzkover, who directs high school programs through CU Science Discovery.

book cover-Sex (this)Sex & Evolution Beneath the Waves (start time: 14:45) Ever wonder about the sex lives of gender-bending fish, desperately virgin elephant seals, and other creatures of the sea? Marine ecologist Marah Hardt has made a career out of it. She speaks with host Susan Moran about her newly published book, Sex in the Sea: Our Intimate Connections with Sex-changing Fish, Romantic Lobsters, Kinky Squid, and Other Salty Erotica of the Deep. Dr. Hardt, who works with the nonprofit Future of Fish, illuminates how sex in the sea is at the heart of healthy and sustainable oceans. The oceans, along with their inhabitants, are under many threats, including overfishing and climate change. She will speak tonight about her book at the Boulder Book Store. For more information on ocean conservation issues, and to get involved here in land-locked Colorado, check out the nonprofit Colorado Ocean Coalition. And listen to previous related interviews, in our series “The Ocean Is Us.”

Pollinators and Insecticides (starts at 10:06).  Although they may be hidden in the chill of winter, crickets, bees and thousands of other insects play a critical role year-round in how we grow the food we eat. Dr. Jonathan Lundgren, a South Dakota-based entomologist, talks with host Susan Moran about how predator insects serve as biological pest controls. Dr. Lundgren’s research on adverse effects of a controversial class of insecticides, called neonicotinoids, on pollinators such as honeybees and monarch butterflies,  has made him the target of political pressure from his employer, the U.S. Department of Agriculture. A watchdog group has filed a whistleblower complaint on Lundgren’s behalf against the USDA. Dr. Lundgren recently started a research and education farm, called Blue Dasher Farm, which promotes regenerative agriculture.

Hubble Space Telescope

Unknown

Today’s show of How on Earth starts with headlines about dark matter, genetic mysteries, jealous monkeys, and polar bears.  We then present a short feature of BBC’s Science in Action about the Hubble Space Telescope.

This is shorter than our usual How on Earth show due to technical difficulties with the phone system for our feature interview with entomologist Jonathan Lundgren; that feature will appear in a future show.

Our Microbes, Ourselves — Special Call-in Show

human gut microbes

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.

CUCafe // Math, Science, Intuition and CFS

pictureToday 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.

pic-julieNext, 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

Evolution of the Human-Horse Bond

9780374224400In 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.
