Bill Gates is on another charitable streak through the Bill & Melinda Gates Foundation with a $100,000 investment to find a way to fight childhood malaria with chocolate and gum.

The gum would be used to test, painlessly, for malaria in children while the chocolate would serve as a way of getting some of the disease-feeding fat out of a patient's body. There's already some promise in these methods and the Gates contribution should certainly keep research going. [Telegraph]
