Aubrey de Grey is an aging researcher of note and one of the founders of the Methuselah Mouse Prize project. The Speculist is currently running an interview with de Grey on his views and work relating to understanding aging and enabling healthy life extension. Well worth reading to see what people on the front lines of research are thinking. A quote: "What Aubrey has to say is explosive - aging is curable. The answer will soon be in our grasp if we devote the necessary resources to going after it."
