Rock Arch Stability (Starts 5:24) How on Earth’s Daniel Strain  talks to Jeffrey Moore, a geologist who studies the West’s iconic rock arches — and watches them for signs that they’re about to collapse.  

Neonicotinoids and Silent Spring – (Starts 15:33) We share a story from H2O radio warning about a pesticide that’s linked to the collapse of honeybee colonies, and growing concerns that it’s dangerous for other forms of life, it’s persistent in the environment and might bring about a new Silent Spring.  This information will be part of this week’s Western Apicultural Society conference in Boulder.  

Hosts: Shelley Schlender and Daniel Strain
