Two exciting stories of ants for you. The first is how some species of ants have designated food testers to make sure a food supply is not poisonous before the rest of the group gets it. You can read about that one here. The second is about a study suggesting that ants are capable of performing simple arithmetic calculations. Here is the actually publication, if you want the sciency version and here is the link to Discovery’s summery.
