Go to the ant

In spite of taking photos of insects for over a decade, it turns out that I don’t have a photo of an ant. So, now that I want to talk a little about how ants deal with epidemics, the only photo I can use is of a termite. Since termites are social animals too, the photo is not inappropriate.

I came across a two year old paper which observed how ant colonies deal with infections. It seems that ant colonies have a rather modularized structure. Every ant does not meet every other member of the colony all the time. They mostly socialize with a reasonably small set of friends and colleagues. These little social cliques intersect, so that they have the “six degrees of separation” that human networks show. What this means is that messages pass very efficiently from one forager to another, or from foragers to the queen and her attendants.

It turns out that when a forager is exposed to an infection, the social network rearranges itself. Each ant meets a much smaller set of friends. As a result, it becomes harder for messages, and infections, to pass from one to another, or to the queen. It is amazing that these measurements were made and have been known for two years already. Interestingly, the colony does not lock down all activity. It cannot afford to do that for long, like human societies. Foraging, defense, breeding continue, but with appropriate caution, namely defensive distancing.

Who says that there is no proof that distancing is effective against an infection? You can quote chapter and verse now (Proverbs, 6 and 6, if you must know). People have gone to the ant, considered her ways, and learnt from it. The lesson is clear: distancing works against infections.

I travel on work. When that gets too tiring then I relax by travelling for holidays. The holidays are pretty hectic, so I need to unwind by getting back home. But that means work.

  1. Fascinating.
    Last week, as I was heating some food in the microwave, I noticed some tiny ants in it. They survived, so out of curiosity, I gave them their own high-power zap. They survived. So, I had to clean them out with a cloth.
