When we think of volcanic conditions, our minds leap to images of vast eruptions like Mount St. Helens in Washington State, or lava oozing down the slopes of Kilauea on the Big Island of Hawaii. With my family, I once visited that lava flow.

We are used to stones being “rock solid” but here molten orange-hot rock oozes across a two-lane road and pours over a cliff, causing clouds of steam to erupt from the Pacific Ocean.

My daughter Ásta, five years old at the time, was understandably very suspicious of the stuff and would not go near the lava flow. It radiated an oven-like heat, even from fifty feet away. 

On the drive home yesterday afternoon I heard a fascinating story on NPR about an ecosystem near and dear to all humans - our skin. Even if bacteria aren't your thing, the story and the findings are really interesting (and actually could be applicable to a wide host of conditions and diseases).
