KGNU - How On Earth

This week we’ll feature CU Medical School Immunologist John Cohen, who has just received the American Association for the Advancement of Science top award for promoting public understanding of Science.  In addition to teaching at the Medical School, Cohen is the founder of Mini Med and the lead “disorganizer” of the Denver Cafe Sci.  We’ll also talk with Emory University researcher Zixu Mao about a new link between Parkinson’s disease and the health of the mitochondria within a cell, and we’ll hear from BBC Science in Action about some top choices in Europe for new Astronomy pursuits. Hosts: Joel Parker, Susan Moran Producer: Shelley Schlender Listen to the show:

Our two features for this week’s show:  Susan Moran interviewed Joel Smith, principal at Stratus Consulting in Boulder, who has been helping the city adapt to climate change—in particular, by smartly managing its water supply; and Tom Yulsman interviewed John Troeltzsch, the Kepler mission program manager for Boulder-based Ball Aerospace, which built one of the key instruments for the mission, as well as the spacecraft itself.

Our guest this week is Todd Neff, who was a science reporter for Boulder’s Daily Camera newspaper and is author of a new book, From Jars to the Stars: How Ball Came to Build a Comet-Hunting Machine, about the history of Ball Aerospace. Neff joins us to speak about that history and the challenges Ball faced when designing and building the Deep Impact spacecraft that intentionally collided with a comet in 2005. We also hear from Jon Stewart of the BBC’s Science in Action about how climate change is actually driving plants downhill. Hosts: Joel Parker, Ted Burnham Producer: Joel Parker Listen to the show:

Government corruption may have lead to poor building practices in Haiti prior to the Jan. 2010 earthquake. Image courtesy of AIDG. This week on How On Earth, University of Colorado earth scientist Roger Bilham joins us in the studio to talk about his latest study, which shows a correlation between the prevalence of corruption in a country and the likelihood of civilian deaths during an earthquake. And Shelley Schlender talks to HOE contributor and astrophysicist Joel Parker about how the science of astronomy can have an impact on the pseudoscientific world of astrology. Hosts: Tom Yulsman, Ted Burnham Producer: Tom Yulsman Listen to the show:

On this week’s How On Earth, we’re joined by the University of Colorado’s Bruce Jakosky, principle investigator on the MAVEN satellite mission that will investigate Mars’ upper atmosphere. NASA granted final approval to MAVEN last fall, and the spacecraft is scheduled to launch in 2013. Also, Ted Burnham speaks with Carol Finn, incoming president of the American Geophysical Union, about the need for scientists to communicate better with the public.
