FEATUREThe Ecology of Tumors   Courtesy of Nasa Ames Research CenterBy perturbing the microenvironment, wounds and infection may be key to tumor development.BY PARAIC A. KENNY, CELESTE M. NELSON, AND MINA J. BISSELLNo tumor is an island. Chemical and physical forces exerted by the diverse cellular populations that surround a tumor - its so-called microenvironment - shape development and progression. Manipulating these 'ecologi

Deciphering How the Sexes Think
Karen Young Kreeger | Jan 20, 2002 | 7 min read
Editor's Note: This is the second article in a series on sex-based differences in the biology of males and females. Future articles in the series will cover sex-based differences in genetics, autoimmunity, and drug metabolism. Stereotypes aside, women and men do process information in singular ways. In the past, tests that tried to pinpoint those variations were fraught with inconsistencies and irregularities. But now, by studying the brain itself, researchers are learning that the sexes use dif
Surpassing the Law of Averages

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
