Real Food (start time 4:20): What we eat , and how we eat, is inextricably connected to our own health as well as the health of the planet. Every decision we make—whether to bake a chocolate cake or buy it from Safeway or at a Farmer’s Market—is full of nuances and even contradictions. Megan Kimble is a writer who became obsessed with wondering how she could make a difference in the world by examining her eating habits. Her just-published book, called Unprocessed: My City-Dwelling Year of Reclaiming Real Food, is her personal journey into the scientific, public health, environmental and political issues related to food. Kimble will speak tonight at the Boulder Book Store, at 7:30, and tomorrow night, July 30, at Tattered Cover in Denver, at 7:00 p.m.
The Buzz About Bees (start time 13:49): Across the United States, buzzing pollinators are key to the growth of countless flowering plants. But many bee species are also disappearing nationwide, due to pesticide use, habitat loss, and other threats. Dr. Sam Droege is a wildlife biologist who studies this vanishing world. He heads up the U.S. Geological Survey’s Native Bee Inventory and Monitoring Lab. For several years he’s also led an effort to photograph bees — very, very close up. Droege’s bee photos are the basis for a new book called “Bees: An Up-Close Look at Pollinators Around the World.”

The Science of Humor (start time: 14:32): Have you ever laughed at something you know you shouldn’t have? Like when someone you know falls down the stairs? 
Polar Bears (starts at 6:30): It is well known that, right now, life for polar bears looks bleak. Warming temperatures mean the season for sea ice cover in the Arctic has become shorter and shorter. As sea ice provides a home and hunting ground for polar bears, both the number of bears and their health has suffered. There is even talk of them becoming extinct. But is this something that we should worry about in Colorado and other non-arctic regions around the world? We don’t have bears, right now we don’t have ice, and we have plenty of other concerns. Dr. Steven Amstrup, the Chief scientist for Polar Bears International, joins us on How on Earth to explain why we should care. He thinks that polar bears are the sentinels of global health and that they provide advance warning of some of the challenges coming to all species. That includes us humans. But he thinks if we act soon, we can save both the bears and ourselves.

Do Fathers Matter? (start time: 3:07) If you’re a father or a son or daughter – which pretty much covers everyone – this interview should hit home. Science journalist Paul Raeburn’s latest book — “Do Fathers Matter? What Science Is Telling Us About the Parent We’ve Overlooked” – explores what seems like a no-brainer question. But the answers he discovers surprised even him. After last week’s pledge drive teaser, we now offer the extended version of host Susan Moran’s interview with Raeburn.
