Just look for this symbol in the upper right hand corner of your search results:
Create a Search Alert
1. Click on it and fill in some info and voila…an RSS feed!
2. Next add the feed to your favorite RSS aggregator [I like Google Reader] and you’ll be alerted when new articles are added to the databases on your specific topic
