Produced in conjunction with the Pasteur Institute, this program examines the destructive effects of the AIDS virus on a microscopic level. By blending computer graphics with live-action photography made possible by an electron microscope, this brief but fascinating program shows the virus in action. It illustrates how persons with AIDS become infected, how the structure of the AIDS virus differs from that of other viruses, and how the AIDS virus systematically attacks and kills healthy cells. While explaining the difficulties involved in developing a cure, the program also presents potential avenues of future research. (10 minutes)
