It's in the air we breathe, the water we drink and the planet we inhabit: oxygen, the most abundant element on Earth. In this hour, we're broadcasting from the annual meeting of the American Association for the Advancement of Science, and we'll talk about oxygen — from the story of its discovery to new discoveries about the biology of oxygen. Plus, oxygen on stage.
