Chronic Infection Persists By Targeting Stromal Cell Network In Lympho
One of the biggest challenges to treating infectious diseases and developing preventive vaccines is the ability of many chronic infections to suppress the immune T-cell response over time. scientists have now discovered one important way in which chronic viral infections are able to evade the immune response by infecting a type of stromal cells in the lymphoid organs called fibroblastic reticular cells. Forests Of Endangered Tropical Kelp Discovered
Forests of a species of kelp previously thought endangered or extinct in deep waters near the Galapagos Islands has just been discovered. This discovery has important implications for biodiversity and the resilience of tropical marine systems to climate change. Word From on High: Jam Cell Calls
Four churches in Mexico have unobtrusively installed Israeli-made cell-phone jammers to thwart those who don't seem to understand they should turn the things off during services or weddings. They're not the only ones to install the jammers. Model Explains How Abused Moms Decide To Leave
Scientists have found a way to help health care providers, social workers and abused women's families understand the stages that these women go through when deciding to leave their partners. 'Normal' Cells Far From Cancer Give Nanosignals Of Trouble
A new study of human colon, pancreatic and lung cells is the first to report that cancer cells and their non-cancerous cell neighbors, although quite different under the microscope, share very similar structural abnormalities on the nanoscale level. The most striking findings were that these nanoscale alterations occurred at some distance from the tumor and, importantly, could be identified by assessing more easily accessible tissue, such as the cheek for lung cancer detection. HFCS Facts: The Facts About High Fructose Corn Syrup
Overview of uses and consumer benefits of this "sweetener [that is] made from corn and can be found in numerous foods and beverages on grocery store shelves in the United States."Also includes questions and answers about the comparison of HFCS to other types of sweeteners (such as table sugar), metabolism of HFCS, and material about the consumption of HFCS and obesity. From the Corn Refiners Association. MicroRNA targets identified in C. elegans
MicroRNAs (miRNAs) are noncoding RNAs that impact almost every aspect of biology. In recent years, they have been strongly implicated in stem cell biology, tissue and organism development, as well as human conditions ranging from mental disorders to cancer. Now, researchers have identified the binding sites of these miRNAs in one of the foremost model organisms, C. elegans, using biochemical means to capture targeted mRNA sequences in vivo. Key Trigger Of Opioid Withdrawal Symptoms Found
Researchers have discovered an important chemical in the brain's neuronal machinery that triggers some of the withdrawal symptoms of opioid drugs like morphine and heroin. A little magic provides an atomic-level look at bonehttp://feeds.scien
University Of Arizona Launches Major Scientific Research Initiative At
The University of Arizona today announces a major new scientific initiative to tackle the grand challenges facing science and society, including global climate change, the fate of water and how energy travels through Earth's ecosystems. The University will lease the 34.5-acre (14 hectare) Biosphere 2 campus in Oracle, Ariz. The UA will develop Biosphere 2 into a center for research, outreach, teaching and life-long learning about Earth, its living systems and its place in the universe.
