There's a ton of neat stuff over at ResearchBlogging.org, a site that aggregates blog posts about peer-reviewed research in the social and natural sciences. You can subscribe to an RSS feed for new posts, including citations. The blog from ResearchBlogging is also interesting, especially when it talks about controversies concerning what counts as legitimate research.
Some posts I've really enjoyed based on my biology degree background have been those at Pharyngula about how vertebrate eyes evolved (which, incidentally, firmly debunks the claim creationists frequently make that eyes are too complex to have evolved biologically) and how plant and animal development differ (and why the differences support the indications that our last common ancestor with plants was most likely a single-celled organism living more than 1.6 billion years ago).
On a totally unrelated topic, my album Penmachine Sessions, which has been sold out in physical CD form since the middle of last year, is available in a whole bunch of digital forms, with the latest being the Amazon MP3 Store. It might be the best place to buy the album of all, since you get unrestricted, high-quality (256 kbps) MP3 files (that's better than the MP3 files I made for myself!) for only 99 cents each, or $8.99 for the whole album. I think it may only be available to U.S. customers for now, unfortunately.
No, I have no idea at all why Amazon labels my album as "explicit"—particularly because it is almost entirely instrumental music with no words!
