You may not like the way Bill Gates made his money, but it's hard to disapprove of how he's spending it -- he's put up $450 million to fund 43 projects to develop innovative approaches to feeding, immunizing, and preventing disease in the poorest people in the world. Some of the winning ideas (all of which may be patented, but must be made available cheaply in poor countries) include making the lifespan of female mosquitoes just shorter than the incubation period of a deadly virus they transmit; engineering a tuber packed with nutrients that can thrive in African soil; and applying Sea-Monkey technology to preserve vaccines for transport in dried form.
