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
