Inconsistent? Good
Though variability is often portrayed as a flaw to be overcome, Harvard researchers now say that, in motor function, it is a key feature of the nervous system that helps promote better or more successful ways to perform a particular action.

Deciding to go left or right
Researchers in a Harvard lab have developed a device, dubbed LADY GAGA, that allows them for the first time to precisely control airborne scents. They have used the device in their work unraveling how animals make navigational decisions based on their environment.
