Highway History
Large compilation of reference material on the history of highways in the U.S. and the Federal Highway Administration. Features information about the developments of the U.S. interstate highway system, specific highways, interstate maintenance, the origins of the highway numbering system, the Zero Milestone (originally intended as the zero marker for all highways), and more. Includes a bibliography and lyrics to selected road songs. From the Federal Highway Administration, United States Department of Transportation. California ISO
The California ISO (Independent Service Operator) is a nonprofit public-benefit corporation "charged with operating the majority of California's high-voltage wholesale power grid. ... [T]he ISO is the impartial link between power plants and the utilities."The "Public and Media Center"features "resources for consumers and the media about California's electrical power system. Contains news and information about the California ISO, the power grid and energy conservation programs." US High School Science Lab Experiences Often Poor, But Research Points
The quality of science laboratory experiences is poor for most US high school students, but educators can improve these experiences by following four key principles of effective instruction, says a new report from the National Academies' National Research Council. Nanotech's Health, Environment Impacts Worry Scientists
The unknown human health and environmental impacts of nanotechnology are a bigger worry for scientists than for the public, according to a new article. Nanotechnology rests on science's newfound ability to manipulate matter at the smallest scale, on the order of molecules and atoms. The field has enormous potential to develop applications ranging from new antimicrobial materials and tiny probes to sample individual cells in human patients to vastly more powerful computers and lasers. Caribbean Children's Literature: A Select Annotated Bibliography
Includes descriptions of collections of stories, proverbs, picture books, poetry, and other children's books on the Caribbean. Titles are mostly from publishers from the United States, England, and Canada. Note: List was compiled in 1998. From Annette Wallace of the Trinidad and Tobago National Library. Two Drugs Better Than One In Lowering Blood Pressure
The combination of aliskiren and valsartan at maximum recommended doses provides significantly greater reductions in blood pressure than does monotherapy with either agent alone in patients with hypertension (high blood pressure), and the tolerability profile of the combined treatment is similar to the two-single agent treatments. The findings are reported in a recent article. However an accompanying comment warns that the potentially life-threatening side effect of high blood potassium makes the treatment unlikely to make it to general practice or even primary prevention in specialist care. Mitochondrial DNA Sequencing Tool Updated
High-tech laboratory tools, like computers, are often updated publicly as their analytical capabilities expand. In the September issue of the Journal of Molecular Diagnostics, NIH grantees report they have developed a second generation "lab on a silicon chip"called the MitoChip v2.0 that for the first time rapidly and reliably sequences all mitochondrial DNA. New Technique To 'See'And Protect Transplants Successful In Diabetic A
Researchers have found a way to overcome a major stumbling block to developing successful insulin-cell transplants for people with type I diabetes. They developed a new technique encapsulates the insulin-producing cells in magnetic capsules, using an FDA-approved iron compound with an off-label use, which can be tracked by magnetic resonance imaging (MRI). The product, tested in swine and diabetic mice, also simultaneously avoids rejection by the immune system, likely a major reason for transplant failure. Ability To Cope With Stress Can Increase 'Good'Cholesterol In Older Wh
Older white men who are better able to cope with stress experience higher levels of so-called "good cholesterol"than men who are more hostile or socially isolated, according to a new study. New Evidence Shows Antarctica Has Warmed In Last 150 Years
New research suggests that Antarctica has been getting gradually warmer for the last 150 years, a trend not identifiable in the short meteorological records and masked at the end of the 20th century by large temperature variations.
