Polar Scientists Welcome 'Strong And Definitive Statement' On Climate
Scientists overseeing International Polar Year have welcomed the first part of the fourth assessment by the Intergovernmental Panel for Climate Change. Hikers Could Die From AMS: Prevention Awareness Needs To Increase
Acute mountain sickness affects almost half of those ascending to heights over 3,000 meters and may lead to life-threatening complications such as pulmonary or cerebral edema. A new study appearing in Journal of Travel Medicine details a prospective on-site study in the Himalayas between July and October 2004 in which the knowledge and practices concerning AMS were examined amongst trekkers. Impact Of Arctic Heat Wave Stuns Climate Change Researchers
Unprecedented warm temperatures in the High Arctic this past summer were so extreme that researchers with a climate change project have begun revising their forecasts. From their camp on Melville Island last July, where they recorded air temperatures over 20ºC (in an area with July temperatures that average 5ºC), the team watched in amazement as water from melting permafrost a meter below ground lubricated the topsoil, causing it to slide down slopes, clearing everything in its path and thrusting up ridges at the valley bottom "that piled up like a rug,"according to one of the scientists. Carbon Nanotubes Yield A New Class Of Biological Sensors
Nanotechnology researchers at the University of Illinois in Urbana-Champaign have demonstrated a tiny, implantable detector that could one day allow diabetics to monitor their glucose levels continuously--without ever having to draw a blood sample. Key Pathway, Potential Drug Targets In Autoinflammatory Disease Uncove
Molecular biologists have detailed the cascade of cellular events behind some potentially dangerous autoinflammatory diseases. In doing so, they not only have gained a greater understanding of the disease process, but have also identified new potential drug targets for diseases ranging from arthritis to cancer. Human Waste On Beach: Sticking To The Sand Might Not Be Such Good, Cle
Microbes that result in beach closures and health advisories when detected at unsafe levels in the ocean also have been detected in the sand, according to a new study. The study found that sand at beaches all along the California coast contained some level of fecal indicator bacteria. At one popular beach in Monterey, California, they found evidence of human waste -- raising doubt about the commonly held belief that some fecal indicator bacteria occur naturally in the sand and are therefore benign. 'Cancer Prognosis Gene' Found To Control The Fate Of Breast Cells
Scientists have discovered an unsuspected role for a gene known to be one of the best predictors of human breast cancer outcome. The gene, called GATA-3, is in a family of genes that guides development of stem cells into mature cells. University of California, San Francisco researchers have now found that GATA-3 is also required for mature mammary cells to remain mature in the adult. In research focusing on mice mammary glands, they found that without GATA-3, mature cells revert to a less specialized, "undifferentiated"state characteristic of aggressive cancer. Three Reasons Not To Believe In An Autism Epidemic
Some people think we are witnessing an autism epidemic. However, according to a new report published in Current Directions in Psychological Science, there are three good reasons not to believe in this so-called epidemic. In A Technical Tour De Force, Scientists Take A Global View Of The Epi
A collaboration between researchers at the Salk Institute for Biological Studies and the University of California at Los Angeles captured the genome-wide DNA methylation pattern of the plant Arabidopsis thaliana - the "laboratory rat"of the plant world - in one big sweep. "In a single experiment we recapitulated 20 years worth of anecdotal findings and then some,"says senior author Joseph Ecker, Ph.D., a professor in the Salk Institute's Plant Biology Laboratory. Mathematical Model Predicts Cholera Outbreaks
A mathematical model of disease cycles developed at the University of Michigan shows promise for predicting cholera outbreaks.
