Part 3 of Mold: Enemy of a Healthy Home. In general, visual observation of active or past microbial growth, or measurement of mold in dust or samples of source material, can be used to establish potential for mold exposure. As inhalation is the primary exposure pathway for molds, air sampling for mold can also be […]
Part 7 of Community Guide to Underage Drinking. While many teens drink, underage alcohol use is not inevitable. It will take everyone in the community to make change happen. All of us can help change attitudes about teen drinking and help replace environments that enable underage alcohol use with environments that discourage it. After all, […]
Part 4 of Geothermal Energy Under Our Feet. Hydrothermal A hydrothermal system is defined as a subterranean geothermal reservoir that transfers heat energy upward by vertical circulation of fluids driven by differences in fluid density that correspond to differences in temperature (see Figure 2). Hydrothermal systems can be classified into two types—vapor-dominated and hot water— […]
Part 9 of United States Climate Change Impact. Rising global temperature All climate models project that human-caused emissions of heat-trapping gases will cause further warming in the future. Based on scenarios that do not assume explicit climate policies to reduce greenhouse gas emissions, global average temperature is projected to rise by 2 to 11.5°F by […]
Part 4 of Lyme Disease. Several antibiotics are effective for treating Lyme disease. These are usually given by mouth but may be given intravenously in more severe cases. Patients treated with antibiotics in the early stages of the infection usually recover rapidly and completely. Most patients who are treated in later stages of the disease […]
Part 9 of Schizophrenia. This is an exciting time for schizophrenia research. The outlook for people with schizophrenia has improved during the last 30 years or so. Although there still is no cure, effective treatments have been developed, and many people with schizophrenia improve enough to lead independent, satisfying lives. This is an exciting time […]
Part 6 of Schizophrenia. It is likely that an imbalance in the complex, interrelated chemical reactions of the brain involving the neurotransmitters dopamine and glutamate (and possibly others) plays a role in schizophrenia. Neurotransmitters are substances that allow brain cells to communicate with one another. Basic knowledge about brain chemistry and its link to schizophrenia […]

Part 8 of Wind Power for the 21st Century. For the past two years, the wind industry has enjoyed record-breaking growth, and industry experts predict that with the extension of the PTC through 2008, the next two years will be record-breakers as well. The challenge for industry is to maintain the long-term wind energy growth […]
Part 5 of Wind Power for the 21st Century. One program R&D project that shows potential for demonstrating a significant increase in overall system performance is the 2.5-MW Liberty wind turbine developed by Clipper Windpower. Clipper completed its prototype in 2005 after only 3 years of R&D. The new machine’s innovative distributed-path powertrain design incorporates […]
Part 1 of Wind Power for the 21st Century. Wind energy technology has come a long way over the past decade. In 1996, the average utility-scale wind turbine was almost as tall as a 12-story building and it produced enough electricity to power about 125 average American homes. At the time, these turbines were considered […]
