For the past few days I’ve been rushing around, first to Woods Hole, Massachusetts, to talk to some people at the Marine Biological Laboratory about the E. coli book, and then on an infinite chain of connecting flights to come out to Aspen to participate in a science-media summit. It’s a relief to be finally sitting down in one place, and the view of the mountains from here making blogging very fine. But until my blood thickens up a little, I probably won’t be writing much.

As I’ve been driving and flying and driving again, I’ve gotten some emails from readers, pointing me to new papers that have come out that they think are blog-worthy. My thanks go
