Ants Freeload? Who Knew?

A very good science section in the NYTimes last week (I lost track of this in draft form), highlighted by a story which disrupts all one's preconceptions about ants. Turns out if you have the patience of Job, or Anna Dornhaus, and track individual ants over their lifetime, some ants freeload just as some humans do. And some "specialists" aren't very good at their jobs.
