Keeping up-to-date in Life Sciences via RSS

SciFeeds delivers the most recent life science literature as it is published direct from RSS feeds. You can browse for over 100 journals within life science by subject, see the most recently updated Table of Contents (TOCs) of each journal, search the content of TOCs (it's a bit slow), see the most 'popular' articles, and if you register, you can do a lot more. There are also links to the full text of articles.
