A Second World War project which involved training pigeons to pilot bombs has won this year's spoof Nobel peace prize.
The Ig Nobel gongs - awarded annually by the science humour magazine the Annals of Improbable Research - celebrate unusual areas of research that "make people laugh, then think".
But the project never took flight because of scepticism from the US military and government officials.
The chemistry award was won by a research team who used a lab technique to separate drunk and sober worms.
