Introducing Quertle

Quertle is a new search engine specialising in biomedical literature but also covering health care. It's still very new (and seems mostly to have content which has been culled from BioMed Central and PubMed Central at the moment) but it's worth keeping an eye on. Quertle's unique-selling-point is the way it searches using "conceptual relationships", supposedly making your search results more relevant. A quick search for diabetes retrieves almost 200,000 hits, so there's certainly plenty to read.
