Why do we have body odour?

We’ve had smelly armpits since before we evolved into modern humans
People spend million every year on covering up their body odour and it's something that we all experience from time to time. But why do our armpits smell? Scientists have now discovered that the smell has been around since before we evolved into modern humans, and that it's caused by a unique enzyme.

Dr Michelle Rudden from the Univeristy of York explains what the research has uncovered.

Are 'malaria-resistant' mosquitoes now a real possibility?

A microbe has been discovered which protects mosquitoes from malaria for life
Scientists have discovered a microbe that completely protects mosquitoes from being infected with malaria. The researchers, from the International Centre of Insect Physiology and Ecology in Kenya, say this could have a significant impact in the battle to eradicate the disease. Dr Jeremy Herren led the study and explains more about the microbe.
