Google has a new search type: Google Scholar. You can reach it on the Google website by clicking on 'More'. It is a beta version so it will hiccup occassionally but it will give you more research article oriented results and less of the home remedies, junior's first grade science project website, etc. It is similar to what you might get with PubMed and MedLine in medical research libraries and institutions. This is important if you are looking for ideas that have been tested.
