Little Urchin

sea urchinNo, not pictures of little urchins doing science, as I sometimes have on this blog.

Instead, it’s a story about the sea urchin’s genome being completely mapped out by researchers. Quite a story, and an important one, since about 70 percent (I learned) of the creature’s genes have analogues in human. This is more overlap than we have with Drosophila, for example, the fruit fly being another well-studied system.

Lots to read about (try here , here, and here for example -the latter is where I got the nice image by Alexandra Eaves, above), and a nice piece on NPR to listen to. So I’ll leave you to it.
