The bee robots vibrated, made air movements, and changed temperature, while the fish robot could change its color, shape, and movement. By emitting certain signals, these robots coerced both bees and fish to adapt their behaviors in a space of about 25 minutes. The fish started to school, grouping together more tightly in response to the signals, while the bees swarmed around a robotic terminal on a vibrating table.

This is a weapon. I went to a technology fair at a local technical university and basically all of their research in various fields was sponsored by the defense industry. non Newtonian fluids are being studied for applications in liquid body armor.
