Water in the Arid West
Today on How on Earth, Beth replays a timely interview with Boulder author Bob Crifasi, a long time water resource manager. His book, on the history and consequences of Front Range water use, is especially relevant now during our longterm drought.Bob works in water management and planning and is an environmental scientist with over 25 yr experience. He was the Water Resources Administrator for the city of Boulder’s Open Space and Mountain Parks Dept. He has served on board of directors of 11 ditch companies and as the president of several, supervising all aspects of ditch operation. We talked about his book, A Land Made from Water.

What’s Your Genetic Risk?
In this week’s show, Beth talks with epidemiologist Genevieve Wojcik. We spoke about her work standardizing what is called the Polygenic Risk Score. This is a composite risk factor, extracted from information on many individual genes that can contribute to a disorder or genetic character. To find out more about her research visit her website.

A Tour of Mycotopia
On this week’s show, Beth talks with author Doug Bierend about his new book, In Search of Mycotopia. He introduces us to an incredible, essential, and often denigrated kingdom of life: the fungi. A growing community of mushroom-mad citizen scientists and devotees are expanding the uses and availability of myriad fungi. From decontaminating landscapes and waterways to achieving food security and novel drugs, you’ll hear about it all.

Burn- A New Look at Our Metabolism
BURNOn today’s show, Beth talks to Herman Pontzer about his new book, Burn, a deep dive into how the human body evolved, and how our species’ deep past shapes our health and physiology. His writing includes fascinating glimpses into both field projects in small-scale societies, including hunter-gatherers and subsistence farmers, in Africa and South America, as well as lab research on energetics and metabolism.(Note: due to the tragic mass murder in Boulder last week, last week’s show was delayed.)
