Ever drive down the road and pass one of those historical markers a lot of places erect and wonder what it's all about? You can do that a lot...and if you stopped at all of them you'd never really get anywhere. Not to worry, there's an app for that. Today on the Best Of Our Knowledge, we'll talk to the people behind Next Exit History, and learn how a stop for coffee on a road trip turned into nationwide historical database.
We’ll also hear how a music teacher sent one of her students on a career path she never imagined…and spend an academic minute fighting plagues from outer space.
