The MacArthur Foundation today announced the recipients of its 2008 MacArthur Fellows (a.k.a. Genius Awards): Among the 25 winners, who will receive $500,000 over the next five years, four were life scientists. Here's the line-up: linkurl:Kirsten Bomblies,;http://www.weigelworld.org/members/kirstenb a plant evolutionary geneticist at the Max Planck Institute for Developmental Biology, studies genetic incompatibility in Arabidopsis as a model for the development of new plant species in shared

Unearthing the Evolutionary Origins of Insect Wings
Jef Akst | Apr 4, 2022 | 6 min read
A handful of new studies moves the needle toward a consensus on the long-disputed question of whether insect wings evolved from legs or from the body wall, but the devil is in the details.
Inventory of Life
Ricki Lewis | Jul 22, 2001 | 8 min read
The idea sounds audacious: catalog all life on Earth within 25 years, a human generation. The All-Species Inventory hopes to do just that, with private funds and the help of a worldwide network of scientists and nature lovers. "It is a dream, but a neat one," says A. Townsend Peterson, curator of ornithology at the natural history museum and associate professor of ecology and evolutionary biology at the University of Kansas, Lawrence. He is one of 40 scientific advisers to the All-Species effort

What’s the Deal with Bacterial Nanotubes?

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?
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
Surpassing the Law of Averages

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
