Measurements from ground - based cameras and a satellite that passed when STEVE was in full swing show that the luminous band was associated with a strong flow of ions in the upper atmosphere, MacDonald, of NASA's Goddard Space Flight Center in Greenbelt, Md., and colleagues conclude.

By shining pulses of light on the altered cells, scientists can switch them «on» or «off,» resulting in the same flow of ions that occurs when neurons fire naturally in the brain. (aaas.org)
It worked like the nozzle on a garden hose, except his version was invisible, regulating the flow of ions with magnetic fields. (discovermagazine.com)
