Conventional Plowing Is 'Skinning Our Agricultural Fields'
Traditional plow-based agricultural methods and the need to feed a rapidly growing world population are combining to deplete the Earth's soil supply, a new study confirms. Annual Prostate Cancer Screening Test Appears To Save Lives
Men who have a yearly blood test to examine their prostate specific antigen levels are nearly three times less likely to die from prostate cancer than those who don't have annual screenings, according to a study presented October 19, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver. Novel Strategy Under Study For Aggressive Leukemia
A novel strategy to hopefully beat into oblivion one of the most aggressive forms of acute myelogenous leukemia combines the strengths of some of the newest leukemia agents, researchers say. Enzyme May Be Target For New Anti-inflammatory Compounds
Virginia Commonwealth University researchers studying the enzyme that triggers inflammation have found that it may be a target for a new class of anti-inflammatory drugs to treat arthritis, asthma, multiple sclerosis, lung and colon cancers and Alzheimer's disease. Long-term Outcomes Studied For Stem Cell Transplant Recipients
Improved techniques and supportive care have resulted in a growing number of long-term survivors of stem cell transplants, though little is known about the impact transplants have on patients' lives long after treatment. To find the answers, researchers from the City of Hope Cancer Center and the University of Minnesota assessed 854 cancer patients that had undergone stem cell transplants, taking a detailed look at the aftereffects of the procedure in the years following the transplant. Endangered Rangers: A Study of the Severe Staffing Shortages Crippling
This March 2004 report explores staffing shortages in national parks due to "chronic under funding and increasing park responsibilities that do not come with additional funding, such as protecting the Statue of Liberty ... from the possibility of terrorist attack."The report describes the situation and includes case studies, suggests short-term solutions, and makes recommendations for the future. Includes a list of information sources. From the National Parks Conservation Association. Stable Sleep Patterns And Regular Routines May Improve Outcomes In Bip
Bipolar disorder, commonly known as manic-depressive disorder, is highly influenced by the circadian system -- the body's internal clock -- and a specific kind of psychotherapy may help decrease irregularities in the circadian system that can trigger key symptoms of bipolar disorder, according to a new study. Learning How The Herpes Virus Invades Cells, Through Use Of Bimolecula
Researchers have uncovered an important step in how herpes simplex virus, HSV-1, uses cooperating proteins found on its outer coat to gain entry into healthy cells and infect them. Further, the study's authors say, they have demonstrated the effectiveness of monitoring these protein interactions using biomolecular complementation. Free-energy Theory Borne Out In Large-scale Protein Folding
Scientists at Rice University have combined theory and experiment for the first time to both predict theoretically and verify experimentally the protein-folding dynamics of a large, complex protein. The interdisciplinary research appears this week in two back-to-back papers in the Proceedings of the National Academy of Sciences. The study involved pioneering efforts to establish comparable experimental and theoretical data, and Rice's team believes the method can be applied to other proteins. Penn Researchers Determine Structure Of Smallpox Virus Protein Bound T
Researchers have determined the structure of an important smallpox virus enzyme and how it binds to DNA. The enzyme, called a topoisomerase, is an important drug target for coming up with new ways to fight smallpox.
