Invertebrate memory: wide-eyed ants retrieve visual snapshots.
Ants retrieve visual memories to guide them en route to their goal. A new study shows that wood ants use object width to retrieve the correct visual memory at the appropriate position along their route. A computational model that accurately reproduces the ants' behaviour raises questions about the underlying mechanisms.
