This blog has very good articles about diseases, genetics, physiology, engineered longevity, etc. During the trial I got one article on must days, and a few days nothing came. Be aware that the blog is described as "The science of engineering healthy longevity." These aren't simple articles for laypersons recommending what foods to eat and how to exercise in order to extend your life. The articles are detailed and it'll help if you have some knowledge of science to understand them.
