Tom’s River (starts at 5:03) Susan Moran interviews Dan Fagin, author of the new book Toms River: A Story of Science and Salvation.  You’ve likely heard of the chemical contamination of Love Canal at Niagara Falls, in the mid-1970s. And the leukemia cluster linked to water pollution in Woburn, Massachusetts,in the mid-80s — made famous by the book Civil Action. But you may not have heard of another cancer cluster –- also linked to industrial chemicals – this one in the small town of Toms River, N.J. Fagin’s book about Tom’s River is far more than a gripping investigation of one town’s struggle; it is a cautionary and illuminating tale about the complexities of finding a causal, not just associative, link between pollution and cancer. And it is a story for anyone concerned about whether the air they breathe, and the water they drink is in jeopardy.

 

2013-03-26 Making Fire on KGNU’s How on Earth Science Show from Shelley Schlender on Vimeo.

Making Primitive Fire (starts at 15:40) Roger Wendell interviews Michael and Lorritta Slayton, who are longtime practitioners of primitive fire making and survival skills. Teaching at rendezvous, schools, and outdoors shows Michael and Lorritta have delighted thousands with their “Backup to the Bic”  demonstrations – how to create a lifesaving fire during an emergency when matches and high-tech lighters won’t do the trick.  Primitive fire making focuses on very old, but tried and true ways of making fire. Today, Michael “Big Smoke” and Lorritta “Flint Woman” Slayton will teach us about Bow Drill Fire Sticks and the flint-and-steel methods for creating fire – assuring us that what we learn from the past will make us wiser for the future.

Headlines:

1. Ice Core Studies
2. How Flu Multiplies
3. Wednesday’s Mini-STEM school features Diana Tomback.  Her topic will be: Evolution and the Origin of Life.

Features:

(5:20 into the show) Shelley Schlender visits the Visindi Circus to learn why some scientists by day become circus performers at night, and how science adds a whole new dimension to circus performances.

(13:00 into the show) Chip Grandits talks with Brian Hynek, for the CU Center for Astrobiology and makes this request:  there are ~17 Billion Earth like planets in the Milky Way according to late-breaking estimates; so in this 10 minute segment, we can just go through the list – Mark will have about 35 ns for each planet to go over the prospects of finding life there.

HEADLINES:

1. Diabetes Drug Metformin – University of Pennsylvania Researcher Morris Birnbaum reports in Nature that Metformin blocks a hormone that tells the liver to melt muscle to make more blood sugar. (Go here for an extended interview with Morris Birnbaum)
2. Climate Change – Research shows that timely political action has a bigger impact than waiting.
3. Boulder Cafe Scientifique – Tonight’s Cafe Sci features CU Boulder researcher Monique LeBourgeois (who we interviewed in detail in previous broadcast) on the topic of kids and sleep.

MAIN FEATURES:

We talk with scientists who are part of two new University of Colorado – Denver studies about alcohol and marijuana – 1) Ben Crost presents a study of marijuana use versus alcohol use which concludes that the minimum drinking age of 21 increases marijuana use among teens (until age 21, alcohol use is lower and marijuana use is higher.  After age 21, alcohol use goes up and marijuana use goes down).  Daniel Rees and Mark Anderson are among the authors on a study of Medical Marijuana and Traffic Fatalities that view the question of who uses what from the other side.  Their study looks at an exception to the rule – the 16 states and District of Columbia with some years now, have had medical marijuana laws.  In these Medical Marijuana states, teen use of marijuana appears to rise at age 18 (that’s the age at which teens no longer need to have their parent’s permission to get a Medical Marijuana card. )  But even more interestingly, in these Medical Marijuana states, traffic fatalities go down.  These authors look at why. (Go here for extended interviews with Crost and Anderson)

We also discuss the new study from the Centers for Disease Control and Prevention that analyzed the link between Body Mass Index (BMI) and death.  BMI is calculated as weight in kilograms divided by height in meters squared study.  The study concluded that while very obese people were likely to die sooner than others, people who were moderately overweight, or even slightly obese, were less likely to die than were people of normal weight, or people who are thin.  Medical doctor and researcher on aging, Ron Rosedale, puts this study in historical perspective, pointing out that the British Medical Journal the Lancet published a similar study in 2006 that concluded that BMI is not a very useful measure of health, and other measures, such as waist to hip ratio and certain hormone levels, might be better at predicting health and longevity.
