From synthetic biology blogger Christina Agapakis, a close-up look at microbial landscapes, including this amazing shot of Penicillium. Christina says:

I just learned that Penicillium, the genus of fungus that makes the white rind on brie cheese and the blue veins in blue cheese, is named after the latin word for "paintbrush" because of its shape.

Christina and I will be on Bloggingheads.tv tomorrow for their Science Saturday show. On the menu: My upcoming book about the future of energy, Christina's interest in designing biology, and our mutual love of cheese.
