Microbial communities are all around us: in our homes, gardens, oceans, even deep underground but their roles in the function of the biosphere are poorly understood. Today Beth spoke with Professor Noah Fierer, at the University of Colorado, in Boulder, who uses DNA to identify microbes in communities ranging from insect microbiomes to Antarctic soils. He has discovered lots of previously unknown bacteria, viruses, and other microscopic critters which are everywhere, eat everything, and perform surprising roles in ecosystems ranging from our guts to Antarctic soils. You can see more at the Fierer Lab website. And check out the New Yorker article on shower heads. With this episode we resume our series on Our Microbes, Ourselves.

Animal scientists have long considered domestic livestock to be too dumb to know how to eat right, but the lifetime research of animal behaviorist Fred Provenza and his colleagues has debunked this myth. Their work shows that when given a choice of natural foods, livestock have an astoundingly refined palate. Like these animals, humans too, have an innate ability to determine what nutrients they need, but we are losing the information from our foods that allow us to make this determination.

Never Home Alone (starts at 4:26) In this week’s How on Earth, Beth interviews Professor Rob Dunn. In his recent book, Never Home Alone, he gives a sneak peak into the natural history of the wilderness in our homes, from the microbes in our showers to the crickets in our basements. You can find out more about his book here, find out more about his lab and research at http://robdunnlab.com, and to contribute to their project visit the iNaturalist site.

Regenerative Medicine (start time: 7:30): We begin our series on regenerative medicine with a discussion of scientific advancements, promises, caveats, regulations, and challenges of regenerative medicine therapies for orthopedic applications, such as stem cell, prolo therapy and PRP (platlet-rich plasma) therapy. Together, these therapies aim to regenerate or replace injured, diseased, or defective cells, tissues, or organs with the goal of restoring or establishing function and structure. Hosts Susan Moran and Beth Bennett interview Jason Glowney, MD, founder of Boulder Biologics, which focuses on regenerative and integrative medicine.

Beth talks with author Ben Goldfarb about his new book, amusingly titled Eager: The Surprising, Secret Life of Beavers and Why They Matter. You’ll gain a better understanding of beavers’ myriad skills, and want to restore beaver populations in our local environments. Spoiler alert, we’ll have copies of his book available during the pledge drive show on Oct. 16.

The National Wildlife Federation just released its report, Safeguarding Summer: From Climate Threats to Iconic Summer Experiences. This report chronicles the latest scientific findings on these trends and shows how we can engage on these issues to save our summers now and for future generations. This week Beth interviews the lead author, Frank Szillosi, about the findings and predictions. You can find the entire report at the NWF website, https://www.nwf.org/Home/Latest-News/Press-Releases/2018/08-15-18-Safeguarding-Summer.

This week’s How on Earth guest, Dr Doug Seals, researches vascular aging. Several events occur as we age that conspire to damage blood vessels, culminating in what is popularly known as hardening of the arteries. But lifestyle modifications to exercise and diet can prevent and even reverse this trend. This week’s show gives background and mechanisms of this aging; next week’s episode will delve more deeply into solutions and interventions. To find out more about the Seals’ lab research visit their website: https://healthyagingproject.org/
