A detailed 3-D model of the human immunodeficiency virus (HIV) won first prize in the 2010 International Science and Engineering Visualization Challenge, sponsored jointly by the journal Science and the National Science Foundation (NSF), announced Thursday (Feb. 17). Currently in its eighth year, the international competition honors recipients who use visual media to promote understanding of scientific research. The criteria for judging the entries included visual impact, effective communication, freshness and originality. That was surely the case for the HIV illustration. Ivan Konstantinov and his team's winning illustration depict the most highly detailed 3D structural model of the human immunodeficiency virus (HIV) ever made. "We consider such 3-D models as a new way to present and promote scientific data about ubiquitous human viruses," said Ivan Konstantinov, one of the scientists who created the illustration. Konstantinov said his team tried to show the viral particle in as real a light as possible. "While working on the HIV model, over 100 articles from leading scientific journals were analyzed," he said. "For this project, Dr. Yegor Voronin from the Global HIV Vaccine Enterprise helped us evaluate the data, shared recent findings and views in the field, and provided general advice."

They cause outbreaks, epidemics, even pandemics that spread from continent to continent. Modern medicine and hygiene have given us some control over devastating infectious diseases, even eradicating smallpox, but, for the most part they remain with us, often preying upon the poorest and most vulnerable.
