Faster-Better-Cheaper? NA The NASA New Millennium Program: Faster,Better,Cheaper craft were small and most of them tested new technologies.Of the 16 projects undertaken,six had failed as of January 1,2000.The resulting success rate,a paltry 63 percent,was significantly below spacecraft normand well below the expectations for reliability that advocates placed on the initiative.

Problem:Malaria >Caused by a parasite transmitted via the bites of mosquitoes The parasites multiply in the liver,and then infect red blood cells.Fever,headache,and vomiting usually appear between 10 and 15 days after infection > Can quickly become life-threatening by disrupting the blood supply to vital organs Source:WHO

Problem:Malaria >A child dies of malaria every 30 seconds There were 247 million cases of malaria in 2006,causing nearly one million deaths,mostly among African children. > Malaria takes an economic toll-cutting economic growth rates by as much as 1.3%in countries with high disease rates Source:WHO
