MU study looks at social structure of prison communities
In community settings, there's always at least one person or perhaps a group of individuals who are most highly respected. Prison systems are no different; one's social status results from interpersonal dynamics. To better understand social structure in California prison communities, Brian Colwell, a researcher at the University of Missouri, recently examined peer relationships among inmates.

Census of protein architectures offers new view of history of life
A new study appearing this month in Genome Research reveals that protein architectures -- the three-dimensional structures of specific regions within proteins -- provide an extraordinary window on the history of life. The research team compiled a global census of protein architectures, and used these relics to plot the emergence, diversification and refinement of each of the three super-kingdoms of life: archaea, bacteria and eukarya.

Mellow in Europe, crazy in America
Reed canarygrass stays put in Europe where it's native, but is aggressively expanding into wetlands across North America. Using this grass as a model, University of Vermont researchers have revealed a new way that some plants become invasive: Multiple introductions of the same species from numerous regions lead to new strains which grow more aggressively than the original plants. With climate change, this kind of invader may become increasingly successful.

Using different media, they have produced resources for researchers, as well as for teaching and communicating science to the broader community.

Alarming acceleration in CO2 emissions worldwide
Between 2000 and 2004, worldwide CO2 emissions increased at a rate that is over three times the rate during all of the 1990s. The accelerating growth rate is largely due to the increasing energy intensity of economic activity and the carbon intensity of the energy system, with increases in population and in per-capita gross domestic product. The increases in energy and carbon intensity constitute a reversal of a long-term trend toward greater energy efficiency and reduced carbon intensities.
