Enlightenment Now // Pledge Drive Teaser

Book coverToday’s pledge-drive show features parts of our recent interview with Steven Pinker.
Enlightenment Now: If you think the world, including the U.S., is falling apart, that the ideal of progress is as quaint as riding to work on a horse and carriage, you’re hardly alone. But you’re wrong, argues  Harvard University cognitive scientist Steven Pinker in his new book. It’s called Enlightenment Now: A Case for Reason, Science, Humanism, and Progress. As he shows in many copious charts and graphs from studies and national statistics, most people are living longer, healthier, safer, freer, and happier lives. And while our problems are formidable, the solutions, Pinker claims, lie in the Enlightenment ideal of using reason and science. Provocative? Yes. Pollyannaish? No, says Pinker. Today’s show features two sections of a recent interview that How On Earth host Susan Moran and KGNU host Joel Edelstein conducted with Pinker.

We will play the full interview on our March 20th science show. Meanwhile, Pinker will discuss and sign his book at two events on the Front Range on Saturday, March 17. He will be at Tattered Cover Book Store in Denver (2526 Colfax Ave.) at 4:00 p.m. Then he’ll speak at 7:00 p.m. at Unity of Boulder Church (2855 Folsom St.) Check with Boulder Book Store about tickets.

Urban Air Pollution: A new culprit

It’s the endless stream of tailpipes on the L.A. freeway which  causes that unsightly smog, nagging cough and chronic respitory problems, right?  Perhaps not any more, a new scientific study helps build the case that the major culprit may now be purchases made at the corner drug store or hardware store.  Chip Grandits speaks with Dr. Brian McDonald of NOAA about perhaps changing tactics for the next stage in the human race’s campaign to keep the air clean and healthy in both the indoor and outdoor environments of the urban areas many of us call home.

A couple headlines focus on related aspects of the changing climate in our Alpine environment and what it really means.  Does it seem like spring comes earlier every year, or is that just your imagination?  Well, the science says probably not, especially if you live in the Northern latitudes.  Science journalist Tom Yulsman, who writes about climate change and beyond in his blog ImaGeo for Discover magazine,  offers a headline  the declining snowpack in the Rockies.

The Starmus Festival

news-placeholder-Starmus-e1517313691450Woodstock.  Lallapalooza. Lilith Fair.  Coachella.  Burning Man.  All famous music and art festivals.  What about…science festivals?  Perhaps a festival with all the “rock stars” of science and space exploration, and while you’re at it, throw in a few music rock stars as well?  Well, that describes the Starmus Festival.  Starmus is the brain child of Dr. Garik Israelian, an astrophysicist who led the team that found the first observational evidence that supernova explosions are responsible for the formation of stellar mass black holes. We talk with Dr. Israelian about the past, present, and future of Starmus.

Spaceport Earth

Spaceport Earth by Joe Pappalargo

Spaceport Earth. This week on How on Earth, we speak with Joe Pappalardo about his book “Spaceport Earth”. With the successes of Space-X and Blue Origin, private and commercial spaceflight is a fast growing business. Pappalardo talks with us about this new space industry and the advances and setbacks that have been faced. In particular, Pappalardo shares his knowledge about the spaceports, new and old, that are part of the new space endeavours. We also talk about how these new launch opportunities provide new ways to support the scientific exploration of both Earth and space.

Plastic Pollution in Ocean

In today’s show we offer two related features:
Plastic Pollution in the Arctic, Green Chemistry  (start time: 7:48) Try to wrap your brain around this statistic: by mid-century the mass of plastic in the oceans will weigh more than the total mass of fish if we continue with ‘business as usual,’ according to the World Economic Forum. Plastic debris, ranging from plastic water bottles to fish nets to invisible fragments, is choking seabirds and mammals all the way up to the Arctic, and quite possibly harming human health. How On Earth host Susan Moran recently attended the Arctic Frontiers conference in Tromso, Norway, where she interviewed one of the speakers, Jenna Jambeck, an environmental engineer at the University of Georgia. Dr. Jambeck directs the Center for Circular Materials Management, where researchers are designing materials and processes that both reduce waste and, like nature itself, reuse waste.

Grassroots Efforts Curb Plastic Pollution (start time: 20:24) In case you’re wondering what’s land-locked Colorado and your daily life got to do with plastic pollution in the ocean, our guest, Vicki Nichols Goldstein, founder and executive director of the Inland Ocean Coalition, discusses regional and national campaigns to curb plastic waste. The Suck the Straws Out campaign is one of many. You can get involved, starting with attending the Colorado Ocean Coalition‘s Blue Drinks happy hour on Feb. 15 in Boulder.

The Longevity Diet

The Longevity Diet by Dr Valter Longo
The Longevity Diet by Dr Valter Longo

This week on How on Earth, Beth interviews Dr Valter Longo, director of the USC Longevity Institute. Dr Longo has researched the fundamental mechanisms of aging in yeast, mice and humans using genetics and biochemistry techniques. He is also interested in identifying the molecular pathways conserved from simple organisms to humans that can be modulated to protect against multiple stresses and treat or prevent cancer, Alzheimer’s Disease and other diseases of aging. In his new book, The Longevity Diet, he describes his research and how to apply it in your life, for health and longevity.
