Surpassing the Law of Averages
Jeffrey M. Perkel | Sep 1, 2009 | 7 min read
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
The Genetics of Society

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.
The Gates of Immortality
Yves Barral | Oct 1, 2010 | 10+ min read
By Yves Barral The Gates of Immortality Did biology evolve a way to protect offspring from the ravages of aging by creating a physical barrier that separates the parent from its young? Dr. Stanley Flegler, Visuals Unlimited he idea that every organism must age was a concept that surprised many biologists. For a long time, aging was thought to be a process occurring only in multicellular organisms. The reason for this arguably odd presumption was that we knew so
Cytogeneticist Receives V.D. Mattia Award for Biochemical Research
The Scientist Staff | Nov 12, 1989 | 5 min read
Joseph Gall, whose investigations have focused on the structure and function of chromosomes, has received the 1989 V.D. Mattia Award from Hoffmann-La Roche Inc. for his contributions to biomedical research. Gall, 61, was presented with the award on September 28 at the Roche Institute of Molecular Biology; the Nutley, N.J.-based company’s basic research center. A native of Washington, D.C., Gall received his B.S. (1949) and his Ph.D. (1952) in zoology from Yale University. From 1952 to 1

How to Create a Successful Fish Tale?
A. J. S. Rayl | Aug 19, 2001 | 10+ min read
More than 80 percent of the planet's living organisms exist only in aquatic ecosystems. Some may harbor secrets to human origins, and clues, treatments--perhaps even cures--for human disease. Some are critical bioindicators that portend the health of the biosphere. Yet, overall, scientists know little about the biochemical processes of these life forms. The vast, rich knowledge within the oceans and freshwater systems on Earth remains virtually untapped, because in the world of biological resear
Ribozymes: Hearkening Back to an RNA World
Jeffrey Perkel | Sep 15, 2002 | 9 min read
Illustration: Ned Shaw LIKE MOLECULAR TOY-MAKERS, ribozyme researchers create tools with evolutionary, diagnostic, and therapeutic applications. Nearly 20 years ago, Tom Cech and Sidney Altman discovered that some naturally occurring RNAs could perform enzymatic reactions, earning these researchers the 1989 Nobel Prize in chemistry. Scientists have now identified several examples of RNA enzymes, or ribozymes. Most make or break the phosphodiester bonds in nucleic acid backbones, but some

NAS Honors Sagan And 14 Other Science Achievers

Three of the 13 awards this year are going to astronomers, including the academy's highest honor--the Public Welfare Medal--which is being given to Carl E. Sagan, 59, David Duncan Professor of Astronomy and Space Sciences at Cornell University, Ithaca, N.Y. Every year, NAS presents this medal (the only award without an accompanying cash prize) to an individual who has made extraordinary use of science for the public good. Perhaps
