Wild Turkeys / Light Pollution (KGNU: How On Earth)

How On Earth, the KGNU science showI’m running the sound board for this Turkey Day episode of How On Earth, the KGNU science show. We start with a live phone interview about the North American wild turkey—not the kind you’ll likely be eating. And we have a pre-recorded interview with Harold Stark of the Cooperative Institute for Research in the Environmental Sciences, who says the light from cities at night can actually change the chemistry of the atmosphere, exacerbating daytime air pollution.

National Perspective on Municipalization / Science of Fall Colors (KGNU: How On Earth)

How On Earth, the KGNU science showThis week I’m pulling double duty as both co-host and sound engineer for How On Earth, the KGNU science show. Energy industry analyst Peter Asmus gives us a national perspective on the municipalization of electrical utilities, as Boulder prepares to decide whether the city government should take over management of the electric grid. And we hear about why leaves change color in the fall, and why it matters.
