Denver Permaculture Guild (starts 3:30) staff and board members explain the goal of permaculture and guild’s annual workshops program taking place this weekend.

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.

Tackling Lead Contamination: Flint and Beyond (start time: 6:27) When you pour yourself a glass of water from the tap, do wonder whether it’s truly clean and safe? How would you know for sure? Flint, Mich., is a haunting example of how a breakdown in water-supply infrastructure, and political integrity, can result in lead contamination of a city’s tap water. Last year, thanks to the dogged investigation of an environmental engineer from Virginia, all of us nationwide were rattled by the disclosure that Flint residents were drinking poisoned tap water and that their city and federal officials were doing little to disclose the problem, much less tackle it. Since then, lead-poisoning outbreaks have emerged in Portland, Ore., Cleveland, Ohio, and elsewhere. Dr. Marc Edwards is the Virginia Tech professor who led the investigation in Flint, and previous water-contamination probes, most notably in Washington, D.C. He talks with How On Earth host Susan Moran about the public health, political and racial-justice facets of the Flint water crisis, and how many more similar crises around the country can be prevented in the future.

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.”)
