The universe is being pushed apart at a faster and faster rate. And the culprit? Dark energy. Astrophysicist Adam Riess shared the 2011 Nobel Prize in Physics for that discovery, and now's your chance to ask him about it--or anything else you've been wondering about the cosmos.

Donald Ingber, director of the Wyss Institute for Biologically Inspired Engineering, discusses how the "organ-on-a-chip" works and why the technology could replace the animal model for drug testing.
