Malaria is one of the world's deadliest diseases--striking some 500 million people a year and killing as many as 3 million of them. So the genetic secrets hidden in those codes could help drug companies design more effective treatments, better repellents and maybe even a vaccine. The information could also be used, some scientists suggest, to breed genetically modified mosquitoes that are resistant to the malaria parasite. Release these mutant bugs in the...
