ray kurzweil is essentially a genius. ... or was at least and became insane shortly during or after? one of the two, or some of both.
either way, that site keeps up on tech/science breakthroughs on the lefthand side, and then on the more right hand side has articles focusing one certain issues that are updated maybe once a year depending on new relevant things goin on.
kurzweil is all about nano bio technologies to cure problems with humans. interesting guy, go wikipedia his name at least if ya dont visit the site above.
