The Bill and Melinda Gates Foundation has found the work so promising it has invested nearly $40 million into genetic strategies to stop mosquitoes from transmitting diseases like malaria and dengue fever.

Not all scientists think that genetically modified mosquitoes are such a good idea. Some scientists think there are too many genetic puzzles to be solved for modified mosquitoes to work. For example: the malaria-causing parasite, which mosquitoes then transmit to humans, is simply too good at evading anything scientists might devise to protect the mosquito. Whenever mosquitoes have developed genes resistant to the malaria-causing parasite, the parasite has always found a way around it.
