Several labs have reported the formation of bacterial nanotubes under different, often contrasting conditions. What are these structures and why are they so hard to reproduce?
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

An external stressor, such as low pH or a mechanical squeeze, can send differentiated mouse cells back to a pluripotent state.
How to Create a Successful Fish Tale?

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
Researchers Receiving MacArthur Fellowships Demonstrate 'Capacity To Make A Difference'
Bruce Anderson | Sep 14, 1997 | 6 min read
PRIZE WITH A PRICE: Science historian Peter Galison has taken some ribbing from his family since being named a MacArthur fellow. One could almost pity Peter Galison. A historian of science at Harvard University, Galison is one of seven members of the scientific community among the 23 recipients of this year's John D. and Catherine T. MacArthur Foundation Fellowships. The coveted five-year awards provide unrestricted support plus health insurance to talented individuals, with no reports or proj
Polar Regions Offer Rich Opportunities For Research
Douglas Siegel-causey | Apr 26, 1998 | 7 min read
Polar science is receiving increased attention this spring with several new developments in the national and international arenas. At last month's meeting of the United States-Russian Joint Commission on Economics and Technological Cooperation, one of the major agenda items was Arctic sciences. This commission has met semiannually since it was initiated in 1993 by U.S. Vice President Al Gore and former Russian Prime Minister Viktor Chenomyrdin to establish new intergovernmental agreements for
The Rodent Wars: Is a Rat Just a Big Mouse?
Ricki Lewis | Jul 4, 1999 | 5 min read
Sometimes it seems as if genome projects are cropping up everywhere.1 But until costs come down, limited resources are being largely concentrated into what Joseph Nadeau, professor of genetics at Case Western Reserve University School of Medicine, calls "the genome seven," an apples-and-oranges list of viruses, bacteria, fungi, Arabidopsis thaliana, Drosophila melanogaster, Caenorhabditis elegans, and mouse, with Homo sapiens in its own category.2 Researchers widely acknowledge that in the rod
