Searching for the HN of medicine

Hi HN,

My girlfriend is a veterinary surgeon, but still seems to either read lots of books or spend her online time on facebook.

I'd like see if I can pique her interest with an HN type forum for topics relating to the medical field.

Basically just looking for a nice simple med news up/downvote board with a simple UI, where one can discuss and debate med topics in a hopefully intelligent manner.

Thanks.
