Eighty-five years ago, almost to the day, astronomers at Lowell Observatory in Flagstaff discovered Pluto. It was considered the 9th planet from the sun. But, several decades later, it was demoted to dwarf planet status. Alan Stern is a planetary scientist heading up the New Horizons mission to study its surface. At a recent lecture in Flagstaff he said there are hundreds of dwarf planets in the Kuiper Belt where Pluto lives.

Omar Badreddin - a computer scientist at Northern Arizona University - believes that's because people don't clean their hands often enough. So he's developed a smart device that can track the number of times hospital staff use hand sanitizer.
