Have you ever been to the doctor and had them listen to your body with a stethoscope? It’s that funny looking thing that looks like a long rubbery tube with a round metal circle on one end and two ear pieces on the other. Doctors always seem to have one handy, but what is it and how does it work? We asked pediatrician Emma Gerstenzang to help us find the answer.Got a question that you need scoped out?

How many times does our heart beat a day?
Most of us know that we have a heart. We know that it beats - sometimes faster, sometimes slower. But just how many times does it beat in a day?

What would happen if I went inside a black hole?
Black holes are super dense spots in space. They have so much gravity that when something falls into a black hole, it can’t escape. We asked UCLA astrophysicist Dakotah Tyler to help us imagine what it would be like if we traveled through one of these dark marvels.Is there a question that’s really pulled you in?

How do 3D glasses work?
3D glasses. Those little paper spectacles with one red lens and one blue. Put ’em on, and suddenly, POW! Images seem to leap right off the screen! Do these glasses play magical mind tricks on our brain? Do they give our eyeballs multi-dimensional superpowers? For a lens into how it all works, we talked to UW-Madison physicist Pupa Gilbert.Got a question that’s really jumping out at you?
