Your Baby’s Microbiome

Your Baby's Microbiome book coverYour Baby’s Microbiome (start time 6:13): This week on How on Earth Beth Bennett interviews Toni Harmon, author of Your Baby’s Microbiome, a look into the role the maternal micro biome plays before and after birth. For a newborn, the biological defenses to diseases and the environment come from the mother. Harmon talks about how the birth process and interactions between the newborn and the mother help build up the immunities that a young child requires.

American Gut Project

american-gut-project-stepsamerican-gut-project-steps-151029The American Gut project is the largest crowd-sourced project ever: to date, over 80.000 participants have contributed fecal, skin, or oral samples. The ambitious goal is to characterize the microbiota of as many individuals as possible to identify the diverse species living in and on us. Beth interviews Dr Embrietta Hyde, Project Manager of the Gut project about results and progess.

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.”

Pledge Drive//Interview with Ed Yong

I Contain MultitudesThis week’s pledge- drive show features a teaser introduction to Ed Yong’s new book I Contain Multitudes: The Microbes Within Us and a Grander View of Life. We play segments from the interview that host Susan Moran recently had with Yong, a science writer for The Atlantic. There still may be a copy left, so call now to have your own, with a pledge of at least $60 to KGNU. Call 303.449.4885.
The book explores the role that invisible yet mighty microbes play in our lives, as well as the lives of so many species with whom they have co-evolved. Yong highlights the research of many scientists in this emerging field who are studying how our gut microbiome influences our brain chemistry, and our overall mental and physical health. The book deepens our understanding of the ecosystems within our bodies as well as the ecosystems in the natural world.
Next Tuesday, Nov. 4, we will broadcast the complete interview with Ed Yong.

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.

Using the Microbiome to Determine Time of Death

MicrobiomeUsing the Microbiome to Determine Time of Death (starts at 5:40): This week on How on Earth, we speak with Jessica Metcalf, an evolutionary biologist, who studies bacteria, specifically the microbiome. One of her research interests is using molecular biology to address basic hypotheses about the role of microbes in corpse decomposition. The time since death, or postmortem interval, also known as (PMI), is important for criminal investigations because it can lead to the identification of the deceased and validate alibis. PMI is critical to both forensic science and pop culture (e.g. TV shows Bones, CSI). Recently she co-authored a paper published in Science, describing how various species of the microbiome can be used to accurately and repeatedly determine the post-mortem interval.

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.

Mighty Microbes in Our Gut & Soils

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.
