This week on How on Earth we speak with 2 notables. NY Times columnist Carl Zimmer describes his exploration of his genome sequence, yes all 3 billion bases! See the series he has produced detailing this journey at https://www.statnews.com/feature/game-of-genomes/season-one/. Then, local cell biologist Gia Voeltz studies how the endoplasmic reticulum (ER) is formed. It is a large continuous structure in the cell, with many different functions and an elaborate shape. The ER was long thought to be the site of synthesis of proteins and other large biologically important molecules. Work in the Voeltz lab has expanded its role considerably. Visit her website to see beautiful moving pictures of ER in action: http://www.voeltzlab.org/#!research-projects/c10g1 Host: Beth Bennett Producer: Beth Bennett Engineer: Maeve Conran Executive Producer: Susan Moran Listen to the show:

Sustainable Agriculture (starts 3:06): We couldn’t feed the planet without nitrogen, a vital nutrient for crops. But most soils don’t produce enough of it to feed anywhere near our 7 billion-plus humans on the planet. So, for nearly a century we’ve been applying synthetic fertilizer—mainly nitrogen and phosphorus -- to grow crops for animals and people. But we have overindulged, creating vast amounts of waste, in the form of nitrogen pollution of waterways and the atmosphere. State and federal regulations have pressured growers to dramatically reduce fertilizer runoff from their fields. But it's not been enough. Another approach – call it the carrot versus the stick – is also taking hold. Major food retailers, wholesalers, and producers, such as Walmart, United Suppliers and Unilever are transforming their whole supply chains, making food production less carbon- and nitrogen-intensive. Suzy Friedman, a sustainable agriculture expert with the Environmental Defense Fund, discusses with host Susan Moran how prog

Quantum Dot Antibiotics (starts 1:00) This programmable antibiotic might keep pace with quickly evolving superbugs.  Unlike most drugs - it's not derived from biological sources.  It's a tiny version of the semiconductors in everything from TVs to iphones to solar panels.  This "antibiotic" is made of nanoparticles, known as quantum dots.  CU Biofrontiers scientists Prashant Nagpal and Anushree Chatterjee explain their new invention. Shrinking Ozone Hole - (starts 15:24) The ozone hole is finally growing smaller - we’ll find out why and how long it will take to completely "heal" the ozone hole from Birgit Hassler, a researcher with the Cooperative Institute for Research in Environmental Sciences (CIRES), a partnership between the University of Colorado Boulder and the National Oceanic and Atmospheric Administration (NOAA).

Pollinators Matter (starts at 4:43): Now that backyard gardens are in full bloom it's a good time to think about pollinators. Honeybees, butterflies, beetles and other pollinators depend on many flowering plants for nectar. And we depend on these pollinators for many foods we love in our diet, from almonds to apples to blueberries. Some of these pollinators, especially honeybees and monarch butterflies, are facing severe threats, here in Colorado as well as globally. Among the culprits are habitat destruction and insecticides called neonicotinoids.  The Butterfly Pavilion in Westminster is not only a popular destination for kids and adults who want to walk among butterflies, and tough tarantulas. It is also conducting research on pollinators and their habitat. Mary Ann Colley, vice president of science and conservation at the Pavilion, discusses with host Susan Moran some pollinator-focused research and educational campaigns.

David Sumpter’s new book is Soccermatics--Mathematical Adventures in the Beautiful Game.  It’s about how the mathematical patterns of how to win at soccer — and much much more — like how a math algorithm of how a slime mold seeks out food can help engineers design an efficient subway system.  The math that helps a soccer team win can also help a business team succeed.  . . . and in this special summer pledge drive show, it's also a chance to hear about KGNU Community Radio and how you can make a difference by making it happen.

The Carbon Farming Solution - (Starts 2:13) Carbon Sequestration is the act of removing carbon from the air and putting it . . . somewhere else.  Kendra Krueger talks with author Eric Tunesmeier about his book, The Carbon Farming Solution, with surprising information such as how driving to a remote organic farm stand can cause more carbon pollution than getting groceries at a close-to-home supermarket.  However, done correctly, including thinking through how to get food to people who need it, Tunesmeier says carbon farming could sequester hundreds of billions of metric tons of carbon from the atmosphere . . .  with plants. Light Pollution -  (Starts 17:36) Over one third of all the people on earth live with such extensive light pollution, they can't even see the Milky Way at night.  That's according to an updated world "light pollution" atlas.  Shelley Schlender talks with NOAA scientist Chris Elveidge about NOAA's "Earth at Night" maps and "The new world atlas of artificial night sky brightness and the ar

Beth interviews Dr Sarah Spaulding, of the Institute for Arctic and Alpine Research here in Boulder. Sarah studies microscopic single celled algae, creatures that photosynthesize but aren’t plants. She discusses their ecological roles in numerous ecosystems as well as challenges in identifying them and her long term goals in studying these elusive but ubiquitous creatures.

Cell Phones & Cancer  (Starts 1:00) A $25 million study reports cell phone radiation boosted brain cancer in rats . . . and rats exposed to radiation lived longer.  Frank Barnes, CU-Boulder Distinguished Professor of Electrical and Computer Engineering, explains these paradoxical findings and implications for people.  (Related stories -- 2011 Cell Phone Radiation and 2014 An Electric Silent Spring) Narcotics Prolong Chronic Pain (Starts 11:35)   CU-Boulder neuroscientist Peter Grace explains his team's new findings about how and why morphine can prolong chronic pain.   Rats with induced nerve pain received morphine for 5 days; their pain lasted nearly three months -- twice as long as the nerve pain for rats that got no morphine.  This is one of the first studies to test long-term effects of treating chronic pain with opioid painkillers.  (Related story: KGNU call-in show on the opioid addiction epidemic) Host/Producer/Executive Producer: Shelley Schlender Listen to the show:

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.
