Any time a 'best science sites' list is created by someone outside the usual self-congratulatory, self-indulgent clique it's worth taking a look, namely because in this instance I found 5 terrific sites I had never heard of before.  I won't say who they are here because I don't want to play favorites but you may find one or two new ones also.

These are not actually all blogs but 50 Excellent Science Blogs Anyone Can Appreciate is a list of good sites nonetheless.   Some are even terrific.   Sure, we don't do the self-promotion others do but neither does John Tierney, and that is pretty good company to be in.  And it's nice to see people recognize quality, even in blogs.
