This seems pretty out of left field. In an era where most of the news is surrounding how machine learning is allowing us to have computers search our images for us, these scientists are looking for alternate ways to offload their image hunting needs. With the sheer increase in numbers for images, I guess every source is helpful.
Aside from how they’re being used here, this seems like a remarkable ability for such a small brain. Again, I think it highlights just how efficient brains are as computers and how much we tend to overlook the skills and abilities of the neighboring branches on the tree of life.
