Our planet's magnetic field is in a constant state of change, say researchers who are beginning to understand how it behaves and why.

This week, we are bringing you the latest urban agriculture related news mixed with lots of good-to-know information and unique projects that are happening across the United States. As efforts to reclaim our food system persist, innovators across the country have been working hard to bring farming back to the urban environment. From low-tech DIY solutions to traditional farming methods, there is a lot to learn and plenty to share. Feel free to share your thoughts and links to your favorite urban agriculture resources, and don't forget to tell us about the urban farming projects in your town! Mike Lieberman.
