Q&A: Biodiversity, distorted
Lauren Urban | May 31, 2010 | 3 min read
There is growing concern about the loss of biodiversity worldwide, but scientists cannot measure how much an ecosystem has changed without good historical data. However, this data may be skewed, with certain time periods, species, or regions better represented than others. linkurl:Elizabeth Boakes,;http://www3.imperial.ac.uk/people/e.h.boakes an ecologist at Imperial College's Natural Environmental Research Council Centre for Population Biology in Berkshire, United Kingdom and her team looked f

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

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
