Kim Binsted talks about her study to whip up tastier space food. Porcini mushroom risotto, anyone? And sleep expert Charles Czeisler talks about how humans adapt to the 24.65-hour Martian day.

Part of the nation's physical landscape is changing. Nature writer and commentator Craig Childs has been watching the dramatic transformation of a mighty river that is running dry.
