Malaria
Malaria is responsible for over a million deaths every year.
Genetic Mutation
About 6,000 years ago humans gained some immunity to the disease through genetic mutations.
During the same era, the mosquito population soared.Ìý Mosquitos carry the parasite that causes malaria.
Could the two events be linked?
Yes, says Professor Sarah Tishkoff of the University of Maryland.

The downside of this genetic mutation is that we are more susceptible to anaemia.ÌýÌýIn particular, sickle cell anaemia and thalassaemia, the subjects of David Weatherall's research.Ìý

Vaccine
Professor Adrian Hill has been working to develop a malaria vaccine.
It's a struggle as the malaria parasite's genome is complex.

An alternative approach is to kill the parasite-carrying mosquitoes that spread malaria.
Chris Curtis is breeding giant mosquitoes that feed on the larvae of these mosquitoes.
