Science For Seniors

Science for Seniors is a good resource on medical research and the major age-related conditions (Alzheimer's, cancer, and so on). They have a good, solid, sensible outlook on anti-aging research: "Make no mistake, there's no Holy Grail, no Ponce De Leonic Fountain of Youth. Instead you have a group of very intelligent men and women in research labs, pharmaceutical companies and universities around the world, discovering new ways to maintain our health as we age."
