How to monetize a small website about research in cancer, ALS

Hi HNers,

I have a small website which receives 2500 unique visitors per month and I wonder how I could monetize it?

The web site is about health, with a focus on cancer and ALS, I add a new article every week when I find something interesting. Often I take a news in English, translate it in French, provide context. I do not publish PR text that can be found in multiple sites on Internet. Even if few articles are in English, half users come from the US and the other half from France. I tried Google Adsense but got no revenue at all during three months so I drop advertising.

Thanks for any comment!
