Stalking Infectious Disease

Graphic: Cathleen Heard Law enforcement officials routinely use DNA fingerprinting as a tool to get the guilty punished. Defense lawyers often rely on the same tool to free the innocent. Though their labs may be less dramatic settings than criminal courtrooms, life science researchers also use DNA fingerprinting, but rather than capturing criminals, their goal is to keep tabs on a different sort of culprit: infectious disease. The technology has revolutionized the way diseases are tracked and th

Psychoactive Drugs and Infectious Diseases
A. J. S. Rayl | Apr 16, 2000 | 10+ min read
For nearly a century, it's been known that drugs of abuse alter the immune system. Since the outbreak of the AIDS epidemic in the early 1980s, however, an explosion of data has given rise to a rapidly evolving area of research. Investigators around the world have shown that such psychoactive drugs as heroin, morphine, cocaine, and marijuana affect both the neurophysiologic and immunologic systems. In recent years, researchers have produced strong experimental evidence that these drugs of a
