How does a primitive nomadic tribe of the Amazon basin cope with the encroachment of Western settlers? NOVA looks at both sides of the story, revealing the misunderstandings between the two cultures.

Medicine was transformed in the 19th century by the discovery of anesthesia; surgery, until then hasty, bloody and completely unable to deal with internal disorders, subsequently took its place in the front rank of medical practice. This NOVA docudrama depicts the pioneers of medicine.

In 1054 AD, the Chinese recorded the explosion of a star so bright that it lit the sky for three weeks, even during the day. It was the explosion of a dying star that was bigger than our sun. NOVA explores this mysterious explosion that led to the discovery of Crab Nebula.

Birds migrate in search of perpetual summer, sometimes traveling as much as 20,000 miles every year. NOVA uses radar to track and identify migrating birds that travel at night, focusing on how they coose routes tat avoid bad weather and make the best of prevailing winds—information that can aid meteorologists.

The advance of medicine depends inevitably on the testing of experimental procedures on human volunteers from either the healthy or the sick. Yet such procedures are often dangerous, and may not be of direct benefit to the subject. NOVA examines how individuals' interests are safeguarded, and asks, under what circumstances experiments should be conducted on children.

Washoe is a chimp more like a person: she talks with her hands. NOVA visits with Washoe and her teachers—Professor Allen Gardner and Dr. Trixie Gardner—to learn more about this unusual animal.

When Paul Kammerer committed suicide in 1926, it was taken by most of his fellow biologists as a tacit admission of guilt that he had faked his experiments purporting to show the inheritance of acquired characteristics. Arthur Koestler joins NOVA in an in-depth examination of Kammerer's infamous experiment.

Nuclear fusion offers the promises of an unlimited, clean source of energy. But achieving fusion has proved one of the most difficult and elusive goals of the physicist. NOVA tells the story of the twists and turns and the international competition along the road toward the achievement of fusion; and details the recent breakthroughs which seem at last to have brought it within reach.

Who were the people that built the first cities -- complete with apartment blocks -- in North America? They were the Anasazi Indians, who lived in the Southwest for some eight or nine thousand years and who then, in about 1300 AD, abruptly abandoned their cities and apparently disappeared. NOVA traces the steps of this ancient sophisticated culture.
