Birds Can Detect Predators Using Smell: Many animal species detect and avoid predators by smell, but this ability has largely been ignored in the study of birds, since it was traditionally thought that they did not make use of this sense.

Why We Sleep: The Temporal Organization of Recovery: “If sleep does not serve an absolutely vital function, then it is the biggest mistake the evolutionary process has ever made,” Allan Rechtschaffen said.

A Pacemaker is a Network
