The high school I went to looked into shifting the start time later because of research like this. Unfortunately, they concluded that it wasn't feasible because of after school sports -- our teams play against other high schools in the area, and the timing of that is based on when all the schools start. So if one school wants to start later, its students wouldn't be done in time for sports games and such. Pretty lame.
