U.S. Army Individual Ready Reserve (IRR)
Information about the IRR, which is comprised of retired or separated soldiers who "may be called upon to fill vacancies in Army Reserve units and may replace Soldiers in Active and Reserve Units."From Globalsecurity.org, an organization that "seeks to reduce reliance on nuclear weapons and the risk of their use." Lateral Thinking Produces First Map Of Gene Transmission
A University of Queensland (UQ) study mapping the evolution of genes has shed light on the role of gene transfer in bacterial diseases. The study, published recently in Proceedings of the National Academy of Sciences USA, was conducted by three scientists at UQ's Institute for Molecular Bioscience. Electric Toothbrushes May Be Better At Fighting Plaque, Gum Disease
Powered toothbrushes with circular bristle heads that rotate in alternating directions are better at removing plaque and reducing the risk of gum disease than ordinary manual toothbrushes, a review of recent studies concludes. Scientists Use X-rays To Measure How Deep 'Deep Impact' Was
Scientists studying the Deep Impact collision using NASA's Swift satellite report that preliminary analyses of X-ray emissions indicate several tens of thousands of tons of material were released. Do Life Events Trigger Mental Disorders?
A new epidemiological study addresses an old question regarding the triggers of mental disorders. Although life events have been consistently reported as precipitating factors for most psychiatric disorders, there is no comprehensive investigation of the relationship between severe life events and psychiatric disorders in the general population. NOAA Offers Electronic Field Guide To Harmful Algal Blooms In Great L
A new Web site, created by the NOAA Center of Excellence for Great Lakes and Human Health, serves as an electronic field guide to the types, locations and habits of harmful algal blooms in the Great Lakes. Brain Imaging Study Explains Williams Syndrome Language Gifts
A team of neuroscientists led by UCLA researchers used a novel magnetic resonance imaging (MRI) technique to create the first detailed images showing how Williams syndrome affects the cerebral cortex. The study finds sharply defined cortical thickening and complexity in the area of the brain important to language. Yucca Mountain: Putting A Limit On Risk
Looking ahead 100 million years, new research puts a maximum limit of 3.6 meters per second on potential ground movement caused by earthquakes at Yucca Mountain, Nevada, the site of the proposed high-level radioactive waste repository. Yucca Mountain has unique characteristics that make it arguably the best location to store hazardous waste, chiefly a water table so low that it is possible to store steel canisters of waste 1000 feet below ground and 1000 feet above the water table. Two questions form the current debate: how dry will the site remain, and what is the risk from earthquakes? New Observations And Climate Model Data
For the first time, new climate observations and computer models provide a consistent picture of recent warming of Earth's tropical atmosphere. Over the past decade, scientific evidence from a variety of sources has implicated human-caused increases in greenhouse gases as a major driver of recent climate change. A key argument used to rebut such findings relates to satellite records of temperature change in the troposphere -- the lowest layer of Earth's atmosphere. 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.
