Picture the African continent without its 214 million annual cases of malaria. Or South America devoid of the scourge of the new terror of the Zika virus. Or developing nations in the tropics not spending hard-won resources fighting dengue fever, an illness so painful that it’s also known as “break-bone fever” because at its height it feels like your own bones are breaking inside your body.
Picture it happening because scientists could do it. Today.
