Oil Leaks and Malaria Control

This week, we discover how disease control and intervention, not climate change, could determine the future prevalence of Malaria across the world and how the oil leak in the gulf of Mexico is affecting wetland ecocsystems in the US. We also investigate if it's more important to eat or to sleep, how a honey trap could detect the pathogens in mosquitoes and how DNA could hold the key to leukaemia. Plus, we find out what happens to light, at light speed, in question of the week!
