Ant nests grow “younger” as they age

Here’s a fascinating twist on aging: western harvester ant nests grow faster and produce more new queens as they get older. Researchers tracked 3,285 nests in Colorado over 34 years, studying each colony as a superorganism rather than focusing on individual ants. The queen can live for more than 40 years, while worker ants are replaced each year, and the nest’s queen production keeps rising even as its growth gradually slows. It’s a striking example of how a living community can follow a very different life course from the creatures we usually think of as aging.
