Physics - A US-Chile team who ironed out the problem of how sheets become wrinkled.
Chemistry - Mayu Yamamoto, from Japan, for developing a method to extract vanilla fragrance and flavouring from cow dung.
Linguistics - A University of Barcelona team for showing that rats are unable to tell the difference between a person speaking Japanese backwards and somebody speaking Dutch backwards.
Literature - Glenda Browne of Blue Mountains, Australia, for her study of the word "the", and how it can flummox those trying to put things into alphabetical order.
Peace - The US Air Force Wright Laboratory for instigating research and development on a chemical weapon that would provoke widespread homosexual behaviour among enemy troops.
Aviation - A National University of Quilmes, Argentina, team for discovering that impotency drugs can help hamsters to recover from jet lag.
