Hot-Vent Microbes: Looking Backward In Evolution For Future Uses
Myrna Watanabe | May 29, 1994 | 7 min read
They live--thrive, even--in boiling water! They feed on sulfur or hydrogen. They could be from one of the moons of Jupiter. In fact, their existence here on Earth has led scientists to realize that planets they hitherto assumed to be lifeless might support life. These thermophilic, or heat- loving, microbes--Archaea--are attracting a small but growing cadre of researchers and serious research funding from the United States governmen

Exotic Species, Locales All In Day's Work For Conservation Biologists
Karen Young Kreeger | Jan 22, 1995 | 9 min read
Traveling to the ends of the earth in pursuit of biological quarry is not part of the job description for the average molecular biologist. But for anthropologist Don Melnick, going to work means trekking through the jungles of Southeast Asia for blood samples from the Javan silvery gibbon and other endangered animals. And the jobs of geneticist John Avise and biologist Brian Bowen entail long nights on tropical beaches waiting for nesting sea turtles. The following are the top ecology journal
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
