SciShow host Hank Green explains the science behind the 2014 Nobel Prize winners in the fields of physics, chemistry, and medicine in a recent episode. The physics prize this year went to a team that developed a blue light-emitting diode (LED), which made possible the white LEDs found in smartphones and LED bulbs. The chemistry prize was awarded to a team that worked on a new fluorescent microscopy technique, and the medicine prize was won by scientists who discovered that the brain has its own internal GPS.
