Cell Phones & Cancer//Narcotics Prolong Chronic Pain

Mybroadband Radiation Brain Cellphone - courtesy WikiCell Phones & Cancer  (Starts 1:00) A $25 million study reports cell phone radiation boosted brain cancer rates in rats . .. and rats exposed to cell phone radiation lived longer.  Frank Barnes, CU-Boulder Distinguished Professor of Electrical and Computer Engineering, explains these paradoxical findings and their implications for people.  (For related stories, check this 2011 science show about cell phone radiation and also this 2014 show about the book, An Electric Silent Spring)

Narcotics Prolong Chronic Pain (Starts 11:35)   CU-Boulder neuroscientist Peter Grace explains his team’s new findings that show how and why rats given morphine, to reduce an inflicted nerve pain, take longer to recover from the pain than rats who receive no morphine.   The treated rats received morphine for only 5 days; their nerve pain lasted nearly three months — twice as long as the nerve pain for rats that received no morphine.  This is one of the first studies to look at the potential long-term effects of giving opioid painkillers for treating chronic pain.  (For related stories, check out this KGNU call-in show on the opioid addiction epidemic)

Our Microbes, Ourselves: Soil Bacteria Treat Stress Disorders

Microbes and Stress Resilience (starts 5:13) If you’re worried that some dirt still clings to your skin under your fingernails after planting or weeding in the garden, fear not. In fact, the more you feel and even breathe its fumes, the better, research suggests. As part of our series called “Our Microbes, Ourselves,” we explore today a newly published study that adds to a growing body of research into the benefits of certain soil and gut microbes on our mental and physical health. Dr. Christopher Lowry, an associate professor of integrative physiology at the University of Colorado-Boulder, discusses with host Susan Moran the study, which he led. It shows that a common soil bacterium called M. vaccae can boost the immune system to help fight stress and inflammation. The research, published last week in the journal Proceedings of the National Academy of Sciences, was conducted on mice, but the health implications for humans are far-reaching.

Foundations for Leaders Organizing for Water and Sustainability // Quantified Self

CU Environmental Center Helps Bring Energy and Water Conservation to Affordable Housing Residents(Starting at 6:30) FLOWS bridges social justice and environmental issues. FLOWS provides leadership training opportunities, green job skills, and free energy and water upgrades while building partnerships between CU students and staff and community members.  They partner with and work primarily for low-income communities for water and energy conservation (the communities most in need of lower energy and water bills).  They joined us to talk about their new training program coming up this May.  Find out more about their program here .

(Starting at 20:14)Michael Skirpan is a PhD candidate at the University of Colorado Boulder in the Computer Science Department. He worked with a collaborative team to create a project called quantified self, an immersive data experience that debuted the last weekend in April.  Listen in to hear more about this half performance-half data experience and find out when it will be happening again here.
