Professor Tim Hunter - Co-Founder of the International Dark Sky Association

06/10/20 • 39 min

My guest today, professor Tim Hunter, owner of the Grasslands Observatory in Tucson Arizona and co-founder of the International Dark Sky Association
The Grasslands Observatory was started in 1985 when Tim Hunter purchased 20 acres of land at a remote location in Southeastern Arizona approximately an hour's drive from Tucson. The site has no horizon obstructions in any direction and sits on a large grassy plateau surrounded by distant mountains. It is at 5000 feet elevation, and there is only minor light pollution from distant Tucson, Sierra Vista, and Nogales, Arizona (and Sonora, Mexico).
Marnie Ogg is talking to some of the brightest minds in their field, about the topic of light pollution and ways to protect our night skies.

Feel Better, Sleep Better, Be Healthier - Your Circadian Rhythms with Professor Sean Cain

The circadian rhythm controls many aspects of our lives, hormone release, hunger, and sleep. Before the invention of the light globe, this important mechanism was set and reset it by the rise and fall of the sun.
My guest today, professor Sean Cain, Associate Professor of Psychology at Monash University, suggests humans may be even more sensitive to light than we already acknowledge.
His laboratory work focuses on individual sensitivities to light and how these insights may help us understand the influences of poor human health, including sleep disorders, metabolic diseases, and depression. He's the current president of the Australasian Chronobiology Society. So Sean, what is chronobiology and how does it fit in with your career right now?.
