Humans have relegated insects to the lower levels of the cognitive totem pole, but scientists are increasingly showing it's a mistake to underestimate invertebrate intelligence. As a case in point, new research by French and Australian researchers suggests honey bees understand the concept of zero - a rare and complex capacity shared by an exclusive group of animals.

Sub-Saharan Matabele ants are ruthless killers, raiding termite mounds two to four times each day. But every once in a while, an ant gets hurt and is hauled back home to recuperate - an astonishing insectoid behaviour unto itself. New research suggests there's even more to it than that - these ants also administer medical care to those wounded in battle.
Like a baseball player running to make a catch, dragonflies are also capable of predicting the trajectory of a moving object, typically its next meal. New research is revealing the mechanisms behind this complex cognitive task, which was once thought to be exclusive to mammals. It's hoped that these insights will lead to innovations in robot vision.
