American Council on Science and Health, 2011: Week Three

By Rich Kozlovich

I was supposed to post this on Saturday, but I have been sick. This week's edition the ASCH's Daily Dispatch really goes all over the place, including one of my favorite topics....DDT. I think you will find the insights on these diverse issues worth exploring. As I have said in the past....this is one of the groups I consistently turn to for the answers. There may be times that you will disagree with them, but at least they have a very simple philosophy; data in search of conclusions versus so many of the groups you will see featured here who have a philosophy of conclusions in search of data,

Enjoy!
