Ecologists who want to save the world’s biodiversity could learn a lot from Kevin Bacon.

One evening in 1994, three college students in Pennsylvania were watching Bacon in the eminently forgettable basketball movie The Air Up There. They started thinking about all the movies Bacon had starred in, and all the actors he had worked with, and all the actors those actors had worked with. The students came up with a game they called Six Degrees of Kevin Bacon, counting the steps from Bacon to any actor in Hollywood. In general, it takes remarkably few steps to reach him.

In my book Microcosm: E. coli and the New Science of Life, I describe how this humble germ helped make modern biology possible–and, in the process, has been engineered to do all sorts of remarkable things. In 2008, I blogged a fresh example, courtesy of Jeff Hasty and his colleagues. They retooled the bacteria to flash in clock-like rhythms. Now Hasty has taken another step forward, rejiggering E. coli so that millions of bacteria can flash in waves. The new paper’s in Nature, and the journal put together a lovely video of the bacteria in hive-mind performance. Check it out below.

Anthony Lane reviews the new Darwin biopic Creation in the New Yorker. As is his habit, Lane manages to write some lovely stuff about a movie he doesn’t care much for (“at once slow and overwrought”). I have to agree with him on this, for example:

[Actor Paul] Bettany, with his jungly sideburns and smooth pate, offers a reasonable likeness of the great man, although he lacks the shaggy overhang of brow, extending far beyond the sunken eye sockets, which lent Darwin not only his solemn frown but, it must be said, his semi-simian air. I sometimes wonder if his tracing of our ancestry began not on his travels, or at his desk, but one morning when he glanced into his shaving mirror.

The Science Tattoo Emporium continues to thrive, long after I first wondered aloud in August 2007 whether scientists had any cool tattoos of their research hidden under their lab coats. I continue to get photos at a regular rate, and as I post new ones, they continue to get noticed anew by places like Digg and Boing Boing.

Initially, I was so stunned by the influx of photos that I posted just about anything that came my way. But as the emporium has grown, I’ve become choosier about which ones I post. So if you are considering sending in your own scientific ink, please read these guidelines:

1. I’m most interested in tattoos that tell a story. The most interesting stories are the ones about how people became scientists. I love this one, for example.

2. When you send in pictures, please include a paragraph in which you tell me who you are and explain the significance of the tattoo. I prefer people to tell the story of their tattoo in their own words.

3. If you’ve been so inspired by the emporium that you’ve dashed out and gotten a tattoo of your own, do NOT immediately take a picture and send it to me. I don’t enjoy staring at raw, bruised flesh. Neither do readers of the Loom. Let yourself heal before grabbing the camera.

4. Make sure the photograph is well lit and at high resolution.
