Here's a new health search engine that supposedly helps find the best treatment or diagnosis of ailments entered into the database. However, if you enter something other than a disease, click on the various options and see what pops up. I entered "crazy" but you can add anything of your own.

They might have fixed this. Proof's link gives no results for me. I also tried "AIDS" as mentioned in this post at Language Log and TechCrunch. The results returned were all sensible-looking.

I put several conditions in and got reasonable answers. However, I am writing an article on evidence-based nursing regulation, and as I've found with other searches, it came up negative.

The Language Log link was a hoot!
