Desert ants have an amazing odor memory

Scientists at the Max Planck Institute for Chemical Ecology used behavioral experiments to show that desert ants are able to quickly learn many different food odors and remember them for the rest of their lives. However, their memory for nest odors seems to differ from their food odor memory: Whereas food odors are learned and kept after a single contact, ants need several trials to memorize nest odors. Moreover, ants forget a nest-associated odor very quickly after it has been removed from the nest. Hence, ants process food and nest odors differently in their brains.
