Background Research For Sources

I have begun to do some initial research on my question. One website which I am finding of incredible help is http://www.newscientist.com/  I am able to look at articles posted over the last twenty years and there are always more coming. However, many of the articles i have read so far do not go into enough detail and therefore I'm going to have to look into other sources to compliment what I already know.
The NASA website http://science.nasa.gov/science-news/science-at-nasa/2002/30sept_spacemedicine/ looks like it has a lot of information on, however it seems quite basic. There is some useful information on it and i do like some of the animations on the site.
http://www.esa.int/ is another useful website. Although it is sometimes difficult to get the exact information which i need, especially as most of what is posted on the site is meant to inform people about jobs or about the objectives of missions undertaken and not about the specifics and technicalities of said missions. 
http://en.wikipedia.org/wiki/Space_medicine has a vast amount of information on my topic, and fortunatlely from what i've read its a wikipedia article which isn't bursting with ridiculous techincal terminology that make it incredibly difficult to understand. There is a lot of useful information on the site, more than I have been able to get through so far, however it focuses primarily on medical conditions with little mention of medical treatment.
http://www.nss.org/community/med/home.html this website is just an incredibly long list of all kinds of sources bases on aeromedicine. It was published 10 years ago and will obviously be slighlty out of date, but it just shows that there isn't a lack of information for me to go through.

Overall i think that internet research is going to be extremely useful to me as there is a wide variety of information available. However, obviously I'm still going to look through textbooks and email speacialists in the field and use other types of sources as I'm sure they will proove invaluable.
