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
Woods Hole Lab Faces Uncertain Future

Celebrating its centennial, the Marine Biological Laboratory adapts to a new era in which money talks as loudly as science WOODS HOLE, MASS.—When Harlyn 0. Halvorson, the new director of the Marine Biological Laboratory in Woods Hole, blows out the candles for his institution’s 100th birthday this summer, no one will have to ask what he wished for. The laboratory needs more money, more room, and more molecular biology if it is to remain in the forefront of scientific research durin
Partners in Research, Competitors in Pay

Early in his career, Russ Altman and members of his lab at Stanford University devised a new data analysis strategy. They drafted the manuscript about their approach and, before sending it to a computer science journal, showed it to the biologists whose raw data they had used. These colleagues expressed great distress at seeing their results in the methods paper, and insisted the team delay submitting the manuscript until they prepared a paper detailing the biological conclusions. Altman agreed
Six Scientists Are Added To Ranks Of Prestigious MacArthur Fellows
Karen Young Kreeger | Sep 1, 1996 | 9 min read
SOLVING REAL-WORLD PROBLEMS: MacArthur fellow Vonnie McLoyd's research combines concepts in socioeconomics, psychology, and anthropology. This year's John D. and Catherine T. MacArthur Foundation fellowships will help six scientists advance their cutting-edge, multidisciplinary projects that extend from the ocean depths to distant stars and planets. With grants of about $250,000 or more, the newly named fellows will be able to finance innovative-even maverick-research ideas that might otherwis
