Today’s show offers two features:
Oil & Gas Impacts (start time: 1:05) Proposition 112, which would require oil and gas wells to be at least 2,500 feet from homes, schools, parks and other buildings, has highlighted mounting public concerns about the health, social and other impacts of extensive drilling along Colorado’s Front Range.  Weld County is  center stage for the latest oil and gas boom; nearly half of Colorado’s 55,000 active wells are located there. Jason Plautz, a Denver-based journalist, discussed with host Susan Moran the science and politics surrounding drilling activities, and whether explosions such as the one in Windsor last December could happen in many other locations. Plautz and Daniel Glick wrote a feature article that has just been published in High Country News.

healthy_planet-imageHealthy Planet+Healthy Humans? (start time: 14:46) Matthew Burgess has been immersed in thinking about and studying how we humans, and the planet we inhabit, can both remain intact—in fact, can both thrive–well into the future. What’s he smok’in, you might ask? In fact, he is a serious environmental scientist at the University of Colorado Boulder. Dr. Burgess and nearly two dozen colleagues authored a recently published scientific paper that applies models to show how we can meet demands of increased populations and economic growth in 2050, while simultaneously achieving bold and effective conservation and climate goals set forth by the United Nations. Dr. Burgess is an assistant professor in Environmental Studies, with an additional appointment in Economics. And he works at the Cooperative Institute for Research in Environmental Science (CIRES), the collaboration between the National Oceanic and Atmospheric Administration (NOAA) and the University of Colorado. He discusses the paper and its implications with hosts Susan Moran and Joel Parker.

Boulder researchers have discovered a key mechanism by which skin begins to develop in embryos, shedding light on the genetic roots of birth defects like cleft palate and paving the way for development of more functional skin grafts for burn victims.  We bring you an interview with lead researchers, Associate Professor Rui Yi of CU Department of Molecular, Cellular and Development Biology, who explains some of the secrets he has been uncovering about “How Skin Begins” [3:27]

Doctor Dan

How do you reconcile a flair for competition and performance with a penchant for science and learning.  We’ll hear from Doctor Daniel Rudnicki, who’s first career was as a competitive and professional figure skater, then after getting an undergraduate degree in Biochemistry and PhD in Organic Chemistry from CU he then founded a biotech company.  But still needing an outlet for his urge to perform he has created the persona of Doctor Dan to bring enthralling and flashy science presentations to local schools.

Cricket Chorus // Foliage Science

This week’s How On Earth features the following two segments:

Late-summer Cricket Chorus (start time: 1:02) One of the most poetic sounds of the end of summer is …. no, not your kids kicking and screaming because summer is over. It’s the sound of crickets, katydids and other melodic insects “chirping” at night. Our focus here is Snowy Tree Crickets in Colorado. They are called “temperature” crickets because you can calculate what the temperature is outside based on how many times these crickets “chirp” in a certain time period. How On Earth’s Shelley Schlender took a stroll recently with two Boulder naturalists — Steve Jones and Scott Severs — to learn more about how, and why, crickets in general make their chirping sound, and why we hear so many of them in the evenings this time of year. Some resources about crickets and their brethren: 1)  http://songsofinsects.com/  2) biology and recordings of nearly all singing Orthopterans (crickets, grasshoppers, katydids), at  Singing Insects of North America (SINA)  http://entnemdept.ufl.edu/Walker/buzz/.

The Science of Aspen (and other) Foliage (starts: 9:40) One of the most iconic images of Colorado is aspen groves quaking in early fall in their brilliant yellow, orange and even red hues. This year, the aspen, and many other plants, are changing colors earlier than normal. Due largely to the extended warm and dry conditions, many aspen leaves are fading and shriveling without turning bright colors. Dr. Jeff Mitton, an evolutionary biologist and a professor emeritus at the University of Colorado Boulder, talks with host Susan Moran about what dictates the timing and intensity of foliage. Dr. Mitton also writes a bimonthly column, called Natural Selections, in the Daily Camera. Here’s one (of many) on crickets.

Email Anxiety // Food Waste

Bedtime laptop workThis week’s How On Earth offers two features:
Work-Email Anxiety (start time: 7:58) If you’re wondering why you often feel anxious on Monday mornings, despite having spent time with your family and friends over the weekend, you might recall the amount of time you spent glued to your smart phone or laptop, checking email because you worried that your boss would be expecting you to be virtually on hand. You’re hardly alone. Samantha Conroy, an assistant professor of business management at Colorado State University, discusses with How On Earth host Susan Moran a new survey-based study (under review) that she co-authored. It found that not only employees but their partners at home suffer from high anxiety when the employee feels pressured to be virtually available via email after hours.

WWF-Food rpt coverFixing Food Waste  (start time: 17:59)  We’re all guilty of it: waste. Tossing out peaches, broccoli and other food that has gone bad in the fridge. Or leaving pasta on our plate untouched at an Italian bistro. More than one-third of all food that is produced in the United States is wasted – in the field, at restaurants, in our own kitchens. The conservation organization World Wildlife Fund recently published a report on the huge environmental and health impacts of food waste, and on what can be done to reduce waste, and ultimately preserve grasslands and other natural habitat. Monica McBride, manager of Food Loss & Waste  at World Wildlife Fund, co-wrote the report, called “No Food Left Behind.” She shares the findings and recommendations with Susan Moran. Check out these resources at WWF on what you can do: A Food Waste Quiz and tips on reducing waste.

Low Carb & Lifespan//Down syndrome & Inflammation

Low Carb Diets and Lifespan (starts 3:00) Dr. Ron Rosedale, MD, gives a “second opinion” about a widely publicized report in the prominent medical journal The Lancet.  The Lancet report contends that low carb diets (40% carbs or less) shorten lifespan, and moderate carb diets (roughly 55% carbs) promote longer lifespans. The study is being hailed as proof for why people should “eat carbs in moderation.” But what if the Lancet study didn’t go low enough on carbs to reveal potential benefits of a VERY low carb diet?  Dr. Rosedale advocates a very low carb, adequate protein, high fat diet, meaning roughly 15% of calories from carbohydrates, 15% from protein and 70% from fat.  (GO HERE for extended version)

Espinosa Lab VisualDown syndrome and Inflammation (starts 15:25) Joaquin Espinosa,  executive director of the Crnic Institute for Down syndrome, discusses the inner workings of cells in people with the genetic mutation known as Down syndrome.  His findings may explain some common characteristics of Down syndrome, such as shorter stature, cognitive challenges, protection from some cancers, and increased risk of pneumonia and Alzheimer’s.   Espinosa’s lab used Boulder’s Somalogic protein analysis tool to inspect thousands of the different proteins our bodies make.  The lab discovered a few hundred proteins that are noticeably different for people with Down syndrome.  These proteins do not specifically influence height or how to take a test.  Instead, they reveal an out-of-balance immune system.

Aerogel as Clear as Glass//New Science Standards for Colorado Schools

Aerogel as Clear As Glass:  (Starts 4:00)   Most aerogels “windows” are kind of foggy looking.  A CU-Boulder science team has created something better.  It’s a liquid made from recycled plant material, a liquid that hardens into a  gel that’s almost as light as air, almost as clear as glass, yet it can insulate against temperature changes.  This “gel” is flexible enough, you can wear it like a glove. And they’ve made it from a rather environmentally friendly source — it’s cellulose, created by microbes “digesting” the beer mash that gets left over after  making beer. 

erin_furtak-webNew Science Standards for Colorado Public Schools (Starts 13:30):  CU Boulder Education Research expert Erin Furtak explains new, more hands-on and interactive way to learn science.  These will soon be part of Colorado Public Schools.  The new science standards will be the first update of Colorado Science Education Standards in well over a decade.  In addition to teachers using these standards, parents can, too.
