Researchers have revealed more detail about the evolutionary "arms race" between bats and moths. One study in the journal Current Biology has shown how a species of bat uses a quiet "stealth mode" of the clicks it uses to locate its prey. Another from a Royal Society journal showed that a moth can distinguish between clicks that mean it has been spotted, and clicks that mean a strike. This allows the moths to choose...

Fitts's law is a model of human movement in human-computer interaction and ergonomics which predicts that the time required to rapidly move to a target area is a function of the distance to and the size of the target. Fitts's law is used to model the act of pointing, either by physically touching an object with a hand or finger, or virtually, by pointing to an object on a computer display using a pointing device. It was proposed...

A light-sensitive protein in the human eye has been shown to act as a "compass" in a magnetic field, when it is present in flies' eyes. The study in Nature Communications showed that without their natural "magnetoreception" protein, the flies did not respond to a magnetic field - but replacing the protein with the human version restored the ability. Despite much controversy, no conclusive evidence exists that...
