Ron Rosedale, MD, Explains Autophagy (starts 17:50)   The Nobel Peace Prize in Medicine has just been awarded to Japanese Scientist Yoshinori Ohsumi  for his discoveries about a process inside our cells known as autophagy.  Autophagy explains how a cell “cleans house” by recycling unessential components, either for food or for building blocks.   Mutations in autophagy genes can cause cells to keep fixing themselves up and living too long.  Think cancer cells.  Conversely, problems that get in the way of autophagy can lead cells to die too soon, such as in the neurologic diseases of Parkinson’s and Alzheimer’s.  The winner of this year’s Nobel Prize in Medicine was not available to discuss autophagy with us.  However, Shelley Schlender did speak with Ron Rosedale, a medical doctor who has been giving presentations about autophagy at science and health conferences for well over a decade.

Alzheimer’s Reversal (starts 2:20) The Alzheimer’s Association calls Alzheimer’s “the only disease among the top 10 causes of death in America that cannot be prevented, cured or even slowed.”  This gloomy outlook means many people avoid screening tests for dementia.  Now Dale Bredesen, a leading scientist from California’s Buck Institute for Research on Aging has documented reversal of early Alzheimer’s in a small case study, largely through lifestyle interventions and a protocol Bredesen describes at MPI cognition.  Activists with ApoE4.info, who have a high genetic risk for Alzheimer’s say the study and Bredesen’s protocol, bolster their efforts to speak openly about ways to foster healthy brains.  For an extended version of the interview with Dr. Bredesen, go to our website.

The Keeling Curve (starts 5:00) Friday, August 12th the Boulder Shambala Center hosts:  Living Beyond Hope And Fear:  Social Confidence And Climate Change.  One leader of the event is the daughter of scientist who created the Keeling Curve for tracking CO2.  Emily Takahashi talks about how the memory of her father’s work inspired her to do the symposium.

Electric Airplanes (starts 8:12) The constant drone of airplanes has many nature lovers wishing planes could be quieter.  It’s starting to happen, thanks to tinkerers and scientists who are building reliable electric powered airplanes, such as Randall Fishman of ElectraFlyer.

Moth Parties (starts 15:03)   It’s that time of year when butterflies, dragonflies and other colorful insects fill the air.  A more humble flying creature is the lowly moth.  Boulder Audubon Society‘s, Pam Piombino .says moths are gaining enough of a following, some people now hold Moth Parties about . . . moths.  (Moth music is “Moths Around the Candle Flame.”)

Quantum Dot Antibiotics (c Shelley Schlender)

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).

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.

Front Cover of The Carbon Farming Solution

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.

Artificial Light at Night

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 artificial Sky.”

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)

chronic pain – courtesy wiki

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)
