The World Health Organization has officially listed cells phones as a possible carcinogen. One expert who’s not surprised at the designation is University of Colorado, distinguished professor Frank Barnes. For decades, Barnes has cobbled together hard-to-find research dollars to study the biological effects of magnetic fields and radiation, including cell phone radiation. In 2008, he chaired a National Research Council report that called for more research into the health effects of all kinds of wireless technologies, including laptop computers, wireless phones, and cell phones. In today’s show, Frank Barnes talks with How on Earth’s Shelley Schlender about cell phone safety.

We talk with Sandi Copeland, Adjunct Professor of Anthropology at CU, about this story:
Two million years ago, two-legged apes roamed the African landscape. Many of these ancient hominins, lived in limestone caves in what is now South Africa. We know this through fossilized skull fragments and teeth from those caves.
But fossils only tell us where an individual died—not where it grew up, or where it traveled during its life. Or do they? New research from the University of Colorado that’s been published in the journal Nature, reveals that male hominins in South Africa grew up in the caves where they died, while the females who died there grew up elsewhere and migrated to the caves as adults.
The research not only sheds light on the behaviors of early human relatives; it makes use of a new technique, pioneered by the CU researchers, to quickly and cheaply analyze the birthplace of fossilized creatures.
This week co-host Susan Moran speaks with Dr. Doug Kenney, director of the Western Water Policy Program at the Natural Resources Law Center at the University of Colorado, Boulder’s law school. Kenney sheds light on the Colorado River Compact and how population growth, climate change, and water politics, are expected to further threaten our future water supply.
And Ted Burnham interviews skeptic and science writer Michael Shermer. His new book, “The Believing Brain,” presents a counter-intuitive explanation for how we form and reinforce our beliefs. Shermer draws on evidence from neuroscience, psychology and sociology to show that we often form beliefs first, and only then look for reasons to believe.

We present the second part of Joel Parker’s interview of Joshua Foer, author of the book “Moonwalking with Einstein: The Art and Science of Remembering Everything” (the full interview can be found here). To round out the “brain theme” of the show, we also include an excerpt of BBC’s Science in Action where Jon Stuart talks with paleontologist Timothy Rowe about how our brains evolved and how scientists can study brains from long dead, ancient mammals.

We learn about new research that indicates that the combination of exercise plus eating high cholesterol foods may help build lean body mass, even in older adults.
What’s more, eating high cholesterol foods such as cheese, beef fat and eggs, when combined with exercise, also seems more heart safe than most people think, according to new research published by Steve Riechman, in the Journal of Gerontology.
And we talk with Larry Gold, founder of the Gold Lab Symposium. The 2011 symposium features scientists, researchers and policy makers discussing how health and science can intersect with healthcare policy, and how to make each one better.
The 2011 GoldLab Symposium was held at CU-Boulder’s Muenzinger Auditorium May 13 – 14th. For audio recordings of the sessions, go here. For videos and powerpoint presentations from the sessions, go to GoldLabColorado.com
Tom McKinnon interviews, via phone, Peter Asmus of Pike Research about Virtual Power Plants. This emerging information technology may help to integrate more renewable power onto the gird. And even save money for customers who are willing to turn down their energy demand when the grid is stressed.
At the recent Conference on World Affairs, Susan Moran sat down with Peter Hildeband, the director of the Earth Sciences Directorate at the NASA Goddard Space Flight Center. He talked about how climate change will impact wildfires in the West.

Today we announce a contest to find new theme music for How On Earth! Our current theme has served us well for more than 20 years, but we feel it’s time to change our tune. We’re looking to local musicians for that new “How On Earth” sound. Check out our Contest Page for more information, and to listen to and comment on submitted music.
Joining us in the studio today is Tom Wasinger, the Grammy-winning producer of our long-standing theme. We talk with him about the history and creation of that theme, and about his hopes for this new theme music contest. We also hear from Anjali Bhatara, of the Laboratory of the Psychology of Perception in Paris. She studies the way music affects the brain, the mind, and the emotions (hear an extended version of this interview). And we’ll get some advice on selecting a memorable new theme from music expert Don Campbell, author of The Mozart Effectand founder of the Institute for Music, Health, and Education here in Boulder.
