The Chronicle [of Higher Education]: Katrina Update Find "announcements from affected colleges, and from associations and government agencies,"including statements from higher-education institutions damaged or closed in the wake of Hurricane Katrina, and offers from other colleges to accept transfer students or provide other assistance. From The Chronicle of Higher Education. Rebooting the Ecosystem Global warming is real. We did it. Now it's time to talk about repairs. By David Wolman from Wired magazine. Short-term Survival Rates Better For U.S. vs. Canadian Heart Failure P Investigators at Yale School of Medicine and the Institute for Clinical Evaluative Sciences, Ontario, Canada, report that elderly heart failure patients hospitalized in the United States have better short-term survival than those in Canada, but lose that advantage over time. UC Riverside Researchers Discover Model Organism For Studying Viruses Researchers at the University of California, Riverside have discovered that a simple worm, called C. elegans, makes an excellent experimental host for studying some of the most virulent viruses that infect humans. UC Riverside researchers have developed a strain of the worm in which an animal virus could replicate, allowing them to map the delicate dance of action and reaction between virus and host. Difference Between Fish And Humans: Century-old Developmental Question Embryologists have helped solve an evolutionary riddle that has been puzzling scientists for over a century. They have identified a key mechanism in the initial stages of an embryo's development that helps differentiate more highly evolved species, including humans, from less evolved species, such as fish. How Do You Simulate Space Junk Hitting a Rocket? A 45-Foot-Long BB Gun Inside a physics lab at the University of Dayton Research Institute BBs are fired at 20,500 mph at spaceships. Sort of. The goal is to test the mettle of the composite fabric or aluminum skins on orbit-bound spacecraft. Experimental Vaccine Protects Nonhuman Primates From Lassa Fever US and Canadian scientists have developed a vaccine against Lassa fever that fully protects nonhuman primates from experimental infection with lethal doses of Lassa virus.The research, published in PLoS Medicine, could eventually lead to development of a vaccine for human use. Currently there is no preventive measure available to halt the spread of Lassa fever, other than rodent control in affected areas. The disease is transmitted to humans from rodents that carry the virus. Newly Identified Gene Cluster On Mouse X Chromosome Provides Insights Researchers at The University of Texas M. D. Anderson Cancer Center have discovered a cluster of 12 genes on the X chromosome in mice that appears to play an important role in reproduction. Reporting in the journal Cell, the scientists showed that knocking out just one of the genes resulted in reduced fertility in male mice. Consumption Of Small Amounts Of Dark Chocolate Associated With Reducti Eating about 30 calories a day of dark chocolate was associated with a lowering of blood pressure, without weight gain or other adverse effects, according to a study in the July 4 issue of JAMA. Bioprospectors Identify Hot New Biofuel-producing Bacteria A bioprospecting expedition to Iceland's famed hot springs has yielded new strains of bacteria with potential of producing hydrogen and ethanol fuels from wastewater now discharged from factories that process sugar beets, potatoes and other plant material. The microbes hold potential for combining energy production with wastewater treatment.
