One team of scientists' research shows that the hairs on a spider, previously thought to be components of one large ear, are actually more like individual ears each. The hairs are able to pick up air movement down to one ten-billionth of a meter, so that they can feel the presence of predators and prey alike. Each hair acts on is own, like a microphone, filtering out background noise and picking up on only relevant information. The next project will be to understand how all these hairs actually work together and act on the spider's nervous system.
