Just outside the hum and buzz of San Francisco, there's a hum and buzz of a different sort. It's the sound of thousands of acres of almond crops being pollinated by bees—bees in such demand that they must be trucked in from as far as Texas.

Hayes Valley Farm is a community-run farm on a former freeway in the middle of San Francisco. The land was slated for condo development but the plan was put off when the economy slumped. Out of the ashes of that dream arose a utopia of a different sort; a suspended reality where fruit trees are grown on what was once a freeway on-ramp choked with cars. Now there are flowers growing out of the double yellow lines, and constant opportunities for children and adults to learn how to grow food and to get dirty doing it. Although the farm has only an "interim use" permit, meaning that it can't last forever, farmers Zoey Kroll and Jay Rosenberg know that the enduring harvest of this project--the truth that even the most outlandish-sounding things are possible if we make them so--will far outlive the farm itself.

The POLENET project takes scientists all over the continent to install equipment, and to get there they leave from Williams Field, an airport near McMurdo Station. Willy Field has a runway equipped to handle the largest aircraft that fly into Antarctica. However, this runway is different; there's no pavement here - this runway is made of ice. POLENET's Stephanie Konfal gives us a look at Willy Field.

Thanksgiving Day weather at McMurdo Station, Antarctica, turned out to be pretty interesting, as weather always can change quickly here. Our holiday weekend greeted us with 50 mph winds, but it didn’t affect the great feast we had in the dining hall.
