A variety of malarial parasites have existed amongst the great apes for millennia, we look at how one of them jumped species and why humans became its preferred host.
And from Antarctica we hear about a potential new treatment for malaria found in a deep sea sponge.
We also look at why improved monitoring is changing our perceptions of earthquakes and follow the story of an endangered Polynesian snail.
