Was directed to the hpb, etc. blog, which I really enjoyed and highly recommend to the scientifically literate. There’s even a recommended reading list along the right-hand column if you want (as I do!) to improve your state of scinetific literacy. The blog deals with the very interesting interface of philosophy and biology. And I now find I’ve got lots of reading to do!
The site that recommended hpb to me is also worth checking out: Gene Expression is a less formal blog dealing with many of the same issues, with contemporary social events and religion often cropping up as well.
