Stalking Infectious Disease
Eugene Russo | Jun 11, 2000 | 8 min read
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

The Infection-Chronic Disease Link Strengthens
Ricki Lewis | Sep 3, 2000 | 6 min read
Infection" is usually associated with an oozing sore, a bout with the flu, or an outbreak in some exotic place. But infectious organisms lie behind many chronic illnesses too, and an increasingly molecular approach to diagnosis is clarifying some of these relationships. An invited panel discussed "The Infectious Etiology of Chronic Diseases" at the second International Conference on Emerging Infectious Diseases, held in Atlanta July 16-19. Chronic diseases take a huge toll. "In the [United St
Illuminating Behaviors
Douglas Steinberg | Jun 1, 2003 | 6 min read
Courtesy of Genevieve Anderson If not for Nobel laureates Thomas Hunt Morgan, Eric R. Kandel, and Sydney Brenner, the notion of a general behavioral model might seem odd. Behaviors, after all, are determined by an animal's evolutionary history and ecological niche. They are often idiosyncratic, shared in detail only by closely related species. But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t
