Interested in Sleep? Try Circadiana.

I've been really enjoying this blog on the biological study of sleep and sleep disorders. Here's an excellent post taking stock of "what the blog is all about," a mission statement that describes what I've enjoyed about the site: occasional science tidbits accessible to lay people, still research-oriented --not bleached into pop science writing, educationally oriented (in that it's actually useful for students of biology), full of good references to other work in the field.

If you're interested in the physical processes behind sleep, or lacking it far too often, this is the place to go: Circadiana: Quarterly Summary.
