It has been known since the turn of the century that there are four human blood groups, based on different red cells and serum characteristics. NOVA looks at the more recent discovery that the different white cell types, as determined by a variety of different molecular markers on the cell surface, open up the possibility of the prevention of disease.

Part one of a two-part series on the subject of man in space, NOVA examines the history of NASA—from the origin of the space race through the triumph of the Apollo programs. By tracing the history of three key programs—Mercury, Gemini, Apollo—we show how the basic challenges surrounding space flight were answered: rendezvous and docking, life support, weightlessness, space sickness, equipment reliability and so on.

In the summer of 1977 Paul MacCready, a California scientist and businessman, won the coveted Kremer Prize. His achievement was to design and build an airplane which completed, unaided, a one-mile figure-eight course entirely under the power provided by the pilot himself. This is the story of those many failures and MacCready's success.

NOVA examines how the heavily polluted air of Athens produces acid rain which is dissolving the marble sculptures and columns; and how iron tiles used extensively in repair 40 years ago are now rusting, expanding and shattering the stone structures.

When first invented 18 years ago, lasers were called "a solution looking for a problem;" nobody could think what to do with them. But in fact research scientists immediately began to exploit their pure colors and near-perfect focusing ability. Today lasers have grown into a billion-dollar business. They are used in construction, manufacturing, clothing, dentistry and medicine. And the future uses of lasers are likely to be of major significance as the means of achieving nuclear fusion and as a very high efficiency communications medium.

In a world that each year loses up to 40 percent of its crops to insects, some form of pest control is desperately needed. But chemical pesticides have backfired. Pesticide-resistant insects frequently develop, and previously harmless insects have become devastating infestations. Farmers have found themselves trapped on a "pesticide treadmill"—the more they spray, the more they have to spray. NOVA examines several alternatives for pest control.

Traditionally zoos were designed neither for people nor animals; barred cages taught people more about their separation from nature than about an animal and its habitat. But just as man has realized that he has all but destroyed much of the world's wilderness and its wildlife, he is realizing that the zoo may be the last refuge for wildlife. NOVA visits several United States zoos to examine a variety of activities of concern today: breeding, public education, creative new animal habitats, and the reintroduction of animals to their natural environment.
