We Breathe Microbes//Noah Fierer

Noah Fierer

We explore the world microbes, and how they’re everywhere, and how the University of Colorado at Boulder has scientists such as Noah Fierer who are trying to track all those microbes down and figure out which ones help us and which ones don’t, and how they interact.  These scientists have studied the microbes on a human hand, the microbes in the air from dog feces, and they’re lastest project is known as Miasma.  That stands for Mapping and Integrated Analysis of Microbes in the Atmosphere.

Pine Beetle Kill // Plight of Sharks

"Empire of the Beetle" by Andrew Nikiforuk

Feature #1: If you live on the Front Range, or just about anywhere else in Colorado, you don’t have to go far to notice huge swaths of rusty brown that have replaced green conifer forests. By now, many people are familiar at least with the devastating effects of the mountain pine beetle. But far fewer may understand just how these voracious insects actually make their living, or that this epidemic — and its causes and triggers — are far more nuanced, and controversial, than meets the eye.  How On Earth co-host Susan Moran talks with Canadian journalist Andrew Nikiforuk about the beetles that have been gorging with impunity on lodgepole pine, spruce and other forests from British Columbia down nearly to Mexico. His new book is called The Empire of the Beetle: How Human Folly and a Tiny Bug Are Killing North America’s Great Forests.Previously, he wrote a best-selling book called Tar Sands.

"Demon Fish" by Juliet Eilperin

Feature #2:  Sharks have a special place in the human psyche.  Perhaps it is a combination of the mystery of the depths of the ocean and natural fear and awe of powerful beasts that can kill humans with a single bite.  But these predators also are key players in the ocean’s ecosystem. The science and legends of sharks are the subject of a new book called “Demon Fish: Travels Through the Hidden World of Sharks” by Juliet Eilperin, the environmental science and policy reporter for The Washington Post.  How On Earth’s Joel Parker talks with Juliet about her book. Listen to the extended interview here.
