By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo

Bioterrorism Research: New Money, New Anxieties
John Dudley Miller | Apr 6, 2003 | 8 min read
Ned Shaw US scientists have reason to feel both heady and scared. The federal government recently released unprecedented billions of dollars to fund bioterrorism research. Yet, the merits of this sudden shift in focus are being debated, and some worry that the money will be squandered or wasted. "I have been really very upset by the focus on bioterrorism," says Stanley Falkow, professor of microbiology and immunology and of medicine at Stanford University. "Everybody's talking about it, but th

If you've ever been confused by the jargon of molecular biology, you are not alone. With biotechnology in the news day by day, it is easy to forget that for many of us--even for some readers of The Scientist--the tools, techniques, and concepts that undergird much of this research are foreign. To help keep up, some scientists are queuing up to learn the bas

Editor's note: Although individual techniques are associated with specific researchers in this article, it should be noted that these investigators commonly use several different techniques to analyze T lymphocyte populations. The human body is constantly under siege. It must defend itself fr
