Thanks for the heads up. 

Nano has great potential for medicine, and I think perhaps in vitamin delivery to certain populations (starving refugees, famines, etc.)My suscreen has it (minerals) and I don't mind, but it DOES need long-term studies.

I come from the land of Monsanto (Saint Louis, Missouri, USA).  Speaking out against GM foods here is heresy.  I was at a party with some food scientists, i.e. grad students working as research interns at Monsanto and they were insistant that genetically modifying food is no different than what humans have been doing for 10,000 years except in a more sophisticated way.  Never mind that people never hybridized plants with animal or bacterial DNA until the likes of these guys were at it. And I said as much to them, however, now that I am eaing paleo, I do see their work as a direct extension of the agricultural revolution. 

More heresy:

Monsanto is a chemical company, not an agricultural company. GMO's were developed so more chemicals that they sell can be sprayed on them and they won't die--that's all.

True that.  Additionally, mandmade fertilizer companies were originally explosvie or military supplies companies.  Petro-chemical industrial complex = military industrial complex = agricultural industrial comples.  Someone csll Max Headroom.

Swords into plowshares?
