I Contain Multitudes–Our Microbes, Ourselves

Multitudes of Microbes (start time: 3:38): You may find it unsettling to learn that our human cells make up only half of our bodies. The other half is a bunch of microbes (in the neighborhood of 40 trillion), all living and reproducing in, and on, our bodies. What’s more, these invisible machines could have a powerful influence on your brain, and on your overall health. Ed Yong, a staff writer for The Atlantic, found it disconcerting at first to learn this when he researched his book called “I Contain Multitudes: The Microbes Within Us and a Grander View of Life.” The book, published earlier this year, explores the mysterious partnerships between humans, and many other species, and the mighty microbes with which we have co-evolved. Today we air the full phone interview that How On Earth host Susan Moran recently had with Yong. We played short clips of the conversation during our fall pledge-drive show last Tuesday. Thanks to you listeners who pledged! And thanks to Yong’s publisher, Ecco, an imprint of HarperCollins, for donating to KGNU several copies, which some generous members are now reading. This interview continues our series called “Our Microbes, Ourselves.”

Our Microbes, Ourselves: Soil Bacteria Treat Stress Disorders

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.

Our Microbes, Ourselves — Special Call-in Show

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.

Holiday Sci & Tech Gifts // Eating Your Heart Out?

 

We 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. Major research projects have noted how some peoples in the world have lived healthy lives past the 100-year mark in communities, such as the Inuit living above the Arctic circle, and the traditional villages of the island, Crete, in the Mediterranean, where cardiac events are completely unknown. ”

2016 Retrospective

2016-resetFor this end-of-the-year How on Earth show, we look back to 2016 with clips from some of our features from the past year: selections from the Our Microbes, Ourselves series, research about Zika, gravitational waves, and carbon farming.  Those are just a few of the topics we covered in 2016, which also included: electric cars, electric airplanes, renewable energy, climate change, using the microbiome as indicator of length of time after death, star gazing, pesticides, life on other planets, planets around other stars, stars in other galaxies, eggs, plant diversity, marine animal sex, wildfires, recent science graduates describing their thesis work, PTSD, light pollution, pollinators, lead in water supplies, Alzheimer’s research, the Rosetta mission, the New Horizons mission, missions to Mars – past, present, and future, sleep, cell phones, and more!
