Keepers of History
Who keeps your history? and how? In West Africa, history is traditionally sung, not written, the duty of the griots, who learn and chant long historical epics. Female groittes sing a different version of history — the women’s side.

From global warming to green economics, scientists are coming to grips with the effects we humans have on planet Earth. Can we continue to grow and prosper while keeping our environment sound? Can we make civilization sustainable? Can we forecast the future for frogs or reindeer or ourselves? A special report from the 2002 Penn State Lectures on the Frontiers of Science.
A Season in Antarctica
Though 98 percent ice, Antarctica isn't flat. In places its rugged peaks top 14,000 feet. It's an upwelling on the order of the Rockies — and the only major mountain range not formed by a collision of tectonic plates. To learn what made it, Andy Nyblade, Sridhar Anandakrishnan, and other geoscientists measure the waves from earthquakes. But first they have to get their equipment out on the ice.
Dieting Italian Style
"Too many cakes." That's what's wrong with the American diet, according to one Italian father.

Nutritionist Claudia Probart takes her students to Rome to find out.
