Fire Resistant Homes

In this fire prone season, we talk with experts about an ancient building technique that might reduce the chance that a building’s going to burn. Unfired, compressed earth blocks are a building material that involves clay, sand and lime.  Our guests are architect-engineer Lisa Morey and one of her clients, Matteo Rabescini, who had such a home built in Superior, Colorado after the 2021 Marshall fire.  You can read more at Colorado Earth/Nova Terra, Heart of A Building, and Lisa Morey’s substack.

Ibogaine for Traumatic Brain Injury – The Science journal Nature has published a small case study about Special Forces veterans who suffer from traumatic brain injury . . . they report good results from one single dose of the illegal psychedelic Ibogaine . . . with careful supervision.

Andrew Linares – Boulder Therapist

IbogaineHuberman Lab discussion with Nolan Williams (Starts 3:45)  Stanford scientists discuss therapeutic use of Ibogaine.

Ibogaine Boulder Therapist Andrew Linares  (Starts 7:00) shares his experiences working with special forces veterans who are taking Ibogaine at a clinic in Mexico, where it is a legal drug.

Lynx – from Endangered Species.org

Lynx Habitat battle this Wednesday (starts 1:00) Denver’s US 10th District Court of Appeals will hear a case about U.S. Forest Service plans for environmental rollbacks in southern Colorado’s Rio Grande National Forest.  They plan to log beetle-killed trees -which may disrupt old growth forest that the endangered lynx needs.  Environmentalists are pushing for more study about the impact of these plans.

The Little Book of Aliens

The Little Book of AliensIn this Halloween episode, we talk with Dr. Adam Frank, an astrophysicst/astrobiologist at the University of Rochester, about his recent book: The Little Book of Aliens. We hear some of the stories and learn about the science of life “out there” – astrobiology – and the past, present, and future search for extraterrestrial intelligence.

Grass-Fed Beef for a Post-Pandemic World

How on Earth’s Beth Bennett talks with authors Ridge Shinn and Lynne Pledger about how regenerative grazing can replace corn-based feedlots, which are responsible for significant climate emissions, nitrogen pollution, and animal suffering. Their book, Grass-Fed Beef for a Post-Pandemic World, outlines a hopeful path out of our broken food system via regional networks of regeneratively produced meat. They talk about how this ancient method of animal husbandry can restore degraded farmland, increase biodiversity, combat climate change by reducing emissions and sequestering carbon and produce nutrient-dense, healthy meat for consumers.  More information at Big Picture Beef.

Also, Shelley Schlender talks with Sarah Johnson, a professor of food, science and human nutrition at Colorado State University, about a recent study indicating that in mice prone to artery disease, those that ate belgian endive reduced the instability of artery plaques. That may be important, because in people, unstable plaques can trigger heart attacks.

Recycling Lithium-ion Batteries

Our lives have been changed by lithium-ion (Li-ion) batteries which are everywhere: in our cell phones, cars, toys, power tools and grid energy storage. Indeed, the 2019 Nobel Prize in Chemistry was awarded to the three scientists who invented and developed them.  As the world manufactures more and more Li-ion batteries, what are the challenges and opportunities for recycling them?  How can we prevent the batteries from ending up in landfills where the toxic metals inside can leak out?   In this episode, we talk with Dr. Zheng Chen, a professor of nanoengineering at the University of California, San Diego, and co-author on the paper “Efficient Direct Recycling of Lithium-Ion Battery Cathodes by Targeted Healing” published a few weeks ago in the journal Joule
