“I’m not a scientist by trade, but I am, in fact, a huge nerd. I study 18th-century British literature, including scientific literature. It was a wild time to be in science. It was also the heyday of the orrery, which provided the initial impetus for my tattoo. (Orreries, as it turned out, involve too many circles to make them feasible for inking on a large scale.) Then I discovered & fell in love with the comprehensive diagrams in Giovanni de’Dondi’s 1364 Il Tractatus Astarii–the plans for the first famous astrarium. My backpiece is of the Mercury wheelwork. Of course, you couldn’t track Mercury with it–de’Dondi followed Ptolemy–but I find his Astrarium a lovely & impressive testament to human ingenuity & curiosity.”

NOTE: I’VE SET UP A FLASH VERSION OF THIS TALK HERE. DON’T BOTHER TRYING TO DOWNLOAD THE QUICKTIME VERSION I DESCRIBED IN THIS POST.

Recently I gave the Discovery Lecture at Carleton University in Ottawa, in which I talked about new developments in evolutionary biology. They sent me a DVD of the talk, and I got a lunatic notion in my head that I would figure out how to get all Web Two-Point-O-Ee and post the lecture online. They told me to go ahead as long as I put a watermark on.

In my new Dissection column over at Wired, I take a look at a remarkable new experiment on E. coli. Scientists randomly rewired the network of genes that control much of the microbe’s activity and found that it generally just kept humming along.

One thing worth adding…in an accompanying commentary, Matthew Bennett and Jeff Hasty at UCSD write,

This conclusion also flies in the face of the popular misconception among opponents of the evolutionary theory, who believe that the genetic code is irreducibly complex.

Three weeks away from the publication of Microcosm, and another kind review has come out, this time from Library Journal:

“To display a broad swath of the people, scientific processes, and discoveries involved in biology, science writer Zimmer (Soul Made Flesh: The Discovery of the Brain-and How It Changed the World) describes a common, luxuriantly growing, usually benign gut bacterium, Escherichia coli, or E. coli. Easily grown in petri dishes, the species has alter egos that can kill its hosts, making the organism a useful laboratory model to explore the basis of heredity.
