Next week the paperback edition of my book Microcosm: E. Coli and the New Science of Life will be published. In the book I approach E. coli as a microscopic oracle that can reveal great secrets about how life in general works. This is not actually a rhetorical stretch; over the past century scientists have put a spectacular amount of work into understanding this bug. And, as I write in the book, E. coli continues to offer surprises. In celebration of the arrival of the paperback Microcosm, I’m going to take a look at some fresh-out-of-the-oven research on E. coli that may change the way you think about life as a whole.

In response to my post on the endorsements for The Tangled Bank: An Introduction to Evolution, a lot of commenters had questions and reactions. I’ve responded in the comment thread here.

Marc Morency, Quartermaster 1st class, USN, writes: “While I am by no means a scientist, I have been fortunate enough to be paid by the government to get ships from pt. A to pt. B serving in the US Navy as a Quartermaster. I was drawn to the navigation when I joined. In my opinion, it is the only job in the military that is both a science and an art. Celestial navigation has been something I have become profoundly interested in since I joined ten years ago. In this age of GPS, it is, in my opinion, more important now than ever for Navigators to remain proficient in the old ways to fix a ship’s position using a sextant and trigonometry. My tattoo is the visual depiction of how to plot a line of position from a celestial body using the altitude intercept method, a method which has been time tested for more than a century. For me it serves as a reminder that while technology improves, the sea remains an unpredictable place and it is up to the older generation to teach the younger the old school ways of doing business.”

My publisher has been sending out copies of The Tangled Bank: An Introduction to Evolution to some leading biologists for possible endorsements when it comes out in October. Here’s what we’re hearing back so far…

“The Tangled Bank is the best written and best illustrated introduction to evolution of the Darwin centennial decade, and also the most conversant with ongoing research. It is excellent for students, the general public, and even other biologists.” —Edward O. Wilson, Harvard University, author of Consilience
