Repelling Pests!

08 September 2008
Presented by Chris Smith, Helen Scales


In this first episode of the Naked Scientists in Africa we find out why mosquitoes are the most dangerous insect in the world and why they find some of us more tasty than others. We also look into a new trial in Kenya to use plants as natural pesticides, find out about a scanning technique that spots cancers as small as a pinhead and hear about new scientific methods being used in South Africa to monitor the ivory trade and stop poachers in their tracks! Plus, in Question of the Week we find out if it's possible for our memory to fill up.
