This week on How on Earth, Beth talks with Dr Seven Hussey about his recent book, Understanding the Heart: Surprising Insights into the Evolutionary Origins of Heart Disease—and Why It Matters. Following his early (34 years old) heart attack, he delved into alternative therapies to heal his heart. In the book he lays out a comprehensive vision of the cardiovascular system and alternative therapies for heart disease.

Air Pollution, Possible Solutions (start time: 2:36) It is ubiquitous and essential to our life. It it is also the cause of some 7 million premature deaths around the world every year, ranking just behind diet, cancer and tobacco as a health risk. That’s the air we breath. Beijing, New Delhi, and London are among the smoggiest, but the Denver metro area isn’t faring so well either. Yet many countries and cities have taken positive steps that have dramatically reduced emissions, from vehicles, smokestacks, crop and animal production, and other sources. Our two guests today have been researching air pollution—its sources, impacts and solutions–and they share their insights and data with How On Earth’s Susan Moran and guest host, journalist Jason Plautz. Beth Gardiner, an environmental journalist based in London, authored the recently published book Choked: Life and Breath in the Age of Air Pollution. And Dr. Frank Flocke is an atmospheric scientist at the National Center for Atmospheric Research, and an author of a major study of air pollution sources on the Colorado Front Range.

Feature #1: Co-host Susan Moran interviews Jonathan Jarvis, director of the National Park Service, who discusses NPS’ quest to lure more people to urban parks, not just the iconic national parks such as Yellowstone and the Grand Canyon. These “threshold” experiences can lead people to appreciate, and help preserve, nature, including national parks. He also speaks of the NPS’ efforts to save the most threatened national parks, especially the Everglades.
Listen to the extended version of the interview here.
Feature #2: A python’s remarkable ability to quickly enlarge its heart and other organs during digestion is leading scientists at the University of Colorado in Boulder to uncover potential new therapies for heart disease. Their research was recently published in the journal Science. The new study also offers clues to how a special combination of fats found in normal foods just might end up as a powerful drug someday for helping a failing heart. How on Earth’s Shelley Schlender reports on the CU team’s research.
