*In “The Great Dying” 250 million years ago, the end came slowly*

The deadliest mass extinction of all took a long time to kill 90 percent of Earth’s marine life–and it killed in stages–according to a newly published report.

It shows that mass extinctions need not be sudden events.

Thomas Algeo, a geologist at the University of Cincinnati, and 13 colleagues have produced a high-resolution look at the geology of a Permian-Triassic boundary section on Ellesmere Island in the Canadian Arctic. (more…)

*Knowledge could assist in tissue replacements, treatments for high blood pressure and diabetes*

COLUMBIA, Mo. – Human arteries – some smaller than a strand of hair – stiffen as a person ages. This stiffening is a factor in cardiovascular disease, the leading cause of death in the United States, because it contributes to the circulatory complications in disorders such as high blood pressure and diabetes. University of Missouri researchers have now used advanced 3-D microscopic imaging technology to identify and monitor the proteins involved in this stiffening process. These findings could eventually help researchers and physicians understand and treat complications associated with cardiovascular disease. (more…)

Political Narratives On Race, Southern Identity Influence National Elections

New research from North Carolina State University shows how attempts to define the South by Republicans and Democrats may have set the stage for President Obama’s victories in Southern states – and shaped the way Americans view themselves.

“Every presidential election is a chance to discuss what it means to be American,” says Dr. Christina Moss, teaching assistant professor of communication at NC State and author of a paper on the research. “The South garnered a great deal of attention in the 2004 election season, and the narratives from that election may provide clues to Obama’s success in 2008.” (more…)
