The James Madison Center: Bill of Rights
Background about the Bill of Rights and James Madison's involvement with its passage in 1791. Includes antecedents (such as the Virginia Declaration of Rights), images of notes for and the text of Madison's June 1789 speech to the House of Representatives proposing the Bill of Rights, text and audio of the Bill of Rights, an article about Madison and the separation of church and state, and related material. From James Madison University. Expandable Electrodes Safe And Effective For Radiofrequency Ablation O
The use of expandable electrodes with multiple tips in the treatment of liver tumors by radiofrequency ablation (RFA) is safe and effective, making it a useful alternative to surgery in selected patients, say researchers from the University of Brescia in Italy. Incorporating biofunctionality into nanomaterials for medical, environ
Researchers have discovered how to use atomic layer deposition to incorporate "biological functionality" into complex nanomaterials, which could lead to a new generation of medical and environmental health applications. For example, the researchers show how the technology can be used to develop effective, low-cost water purification devices that could be used in developing countries. [Ironic] LONDON: A jailed cocaine dealer is working as Santa Claus on
John Tams, who dons beard, boots and red suit to work in a cafe's Christmas grotto, said he wanted to give something back to the community... Lifestyle Changes Can Improve Male Sexual Function, According To New S
In a study published in the February 2007 issue of the American Journal of Medicine, researchers report that erectile dysfunction was significantly and independently associated with age, cardiovascular disease, diabetes, and lack of physical activity. There was an especially high prevalence of erectile dysfunction among men with hypertension and diabetes, suggesting that screening for erectile dysfunction in these patients may be warranted. Turning A Blind Eye To Bigeye Tuna
Bigeye tuna are under threat because authorities are failing to recognize the dire extent of overfishing. If protection measures are not put in place, says WWF and TRAFFIC, the tuna stocks are at serious risk of collapse. Up to 60% of the bigeye tuna catch in the Eastern Pacific are small, juvenile fish, and the proportion of these is rising, says a new report from WWF and TRAFFIC, the wildlife monitoring network. Driving Force Of Evolution? Evolution Of Proteins Linked To Species'Me
"Survival of the fittest"has popularly described evolution for more than a century, but a new study provides further evidence that random genetic mutations over millions of years may also play a powerful role. The evolution of proteins -- the organic compounds that determine the structure and function of living things -- can be linked to a species'metabolic rate. The findings suggest neutral processes independent of natural selection are also important in governing evolution. Scrubbing Sulfur: New Process Removes Sulfur Components, Carbon Dioxid
Researchers have developed a reusable organic liquid that can pull harmful gases such as carbon dioxide or sulfur dioxide out of industrial emissions from power plants. The process could directly replace current methods and allow power plants to capture double the amount of harmful gases in a way that uses no water, less energy and saves money. Many Children Discontinuing Use Of ADHD Medication
Social stigma and feeling lifeless and/or alienated from one's peers are some of the reasons why children and adolescents stop taking prescription stimulant medications used to treat attention deficit-hyperactivity disorder (ADHD), according to a new study published in the Journal for Specialists in Pediatric Nursing.
