In this week’s show, Beth interviews Dr. Ivan Liachko, CEO and Co-Founder of Phase Genomics, a startup biotech company recently funded, in part, by the Bill and Melinda Gates Foundation. The company is using a new technology that allows researchers to pair plasmids, which are small non-chromosomal pieces of DNA, with the bacterial species carrying them. This is key to identiying the species in the microbiome that carry antibiotic resistacne genes. In the following interview, which starts at about 6:00 Dr Liachko describes the method and its implications. You can see more about the technology at their website.

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
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.

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.
