This week, we fly up into the sky to peer into the lives of some brainy birds. We discover how cuckoos manage to convince other bird species to bring up their young, and reveal how corvids are able to problem solve and use tools to get their food. Plus, we find out how the expanding field of biotechnology is helping to develop new drugs and disease treatments in South Africa.
