How do bees navigate?

Professor Mandyam V. Srinivasan of the Visual Sciences Group at the Australian National University in Canberra should know. He has just won the Australian Prime Minister's science prize for his work and receives a gold medal and a cheque for A$300,000. His research interests are:

Understanding the principles of visual processing in small animals, such as insects, that possess relatively simple nervous systems but nevertheless display a rich behavioural repertoire. My research seeks to elucidate principles of flight control and navigation, and to explore the limits of the "cognitive" capacities of small brains.

He applies this work to help produce small pilotless aircraft controlled by computers with the same power as a bee's brain.
