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
Elemental Shortage
Brendan Borrell | Nov 1, 2010 | 10+ min read
By Brendan Borrell ELEMENTAL SHORTAGE The world is running out of cheap phosphorus, the element that lies at the heart of great agricultural advances and thorny environmental problems. Biologists are only now beginning to understand what it means for evolution and human health. James Elser at a study site in southern Norway Although a limnologist in Phoenix and a molecular biologist in Atlanta have never met before, a single element ties them together.
Illuminating Behaviors
Douglas Steinberg | Jun 1, 2003 | 6 min read
Courtesy of Genevieve Anderson If not for Nobel laureates Thomas Hunt Morgan, Eric R. Kandel, and Sydney Brenner, the notion of a general behavioral model might seem odd. Behaviors, after all, are determined by an animal's evolutionary history and ecological niche. They are often idiosyncratic, shared in detail only by closely related species. But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t
Biochemical, Reagents Kits Offer Scientists Good Return On Investment

Investment Author:Holly Ahern If you were to ask several life scientists to name a particular biochemical product that they simply could not do without, you'd probably get a myriad of answers that would mirror the research interests of the group you questioned. A molecular evolutionist trying to differentiate two closely related species of monkeys by restriction fragment-length polymorphism (RFLP) analysis might cite restriction enzymes, which can cut DNA into pieces of varying length.

Do Energy Transport Systems Shape Organisms?
Steve Bunk | Dec 6, 1998 | 8 min read
Research Research: Do Energy Transport Systems Shape Organisms? By Steve Bunk Brian Evans/lightSpace BEAUTY OF LIFE: This computer-generated image illustrating how organisms grow proportionally represents only a tiny portion of image E on the following page. Could it be that the way organisms transport resources is the most pervasive influence on biological structure and diversity? Curious though it may seem, recent research suggests that networks for transporting the materials essential

Bats harbor diverse pathogens, including Ebola, Marburg, SARS, and MERS viruses. Understanding why could help researchers stymie deadly emerging diseases.
Soybeans Hit Main Street
Barry Palevitz | Mar 19, 2000 | 8 min read
Once a favorite of Chinese emperors, tofu is now big time. From supermarkets to health food boutiques, diet-conscious Americans are buying soybeans, not just as tofu but in infant formula, soy milk, and soy burgers. Soy even has the Food and Drug Administration's seal of approval. Last October the FDA responded to a petition by Protein Technologies International, a St. Louis-based DuPont company specializing in soy products, by authorizing claims that soy protein is good for the heart.

Genetic Parasites and a Whole Lot More

Photo: Ori Fragman, Hebrew University Hordeum spontaneum, the plant studied for BARE-1 retroelements. With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c
