Over at Dangerously Irrelevant there is a very cool project called The Push– where a wiki is being forwarded to collect blogs that focus on specific content areas. There is an extensive list of Science Blogs to add to your RSS reader of choice. There are blogs for several other content areas as well- math, English, art, drama, etc. Check it out and add a blog if you see something exceptional that is missing.
Applications for Science Teachers: Teachers of science will find resources on specific areas of science as well as blogs from working scientists, science teachers of various levels, and examples of science classroom blogs.
