The October 2007 issue of Scientific American is out and it is chock full of good articles this month.
Jeffrey Sachs has a good column arguing the importance of controlling the spread of malaria in the developing world. I did a post on malaria back in July, which included a link to a very moving article in National Geographic.
The online edition of Sachs' column links to the web site of an organization called Malaria No More, which "engages individuals, organizations, and corporations in the private sector to provide life-saving bed nets and other critical interventions to families in need." You can also link to Malaria No More's web site here if you would like to make a donation to provide mosquito repelling bed nets for people in need.
