Hamming It Up at Radio Meets
When amateur radio operators, or hams, get together, the emphasis is on technology and gossip, not fashion. By Mark Baard. Brace for the Ray-Tracing Future
With the release of a ray-traced version of Quake 4, will an ultra-realistic method of rendering scenes see the light of day? In Gear Factor. Who Laid The First Egg? Scientists Closer To Linking Embryos Of Earth'
A decade ago, geobiologist Shuhai Xiao and his colleagues discovered thousands of 600-million-year-old embryo microfossils in the Doushantuo Formation, a fossil site near Weng'an, South China. In the February issue of Geology, the journal of the Geological Society of America, Xiao will report discoveries about the intermediary stage that links the embryo to the adult. Parents Blind To Children's Risk Taking &Skilled Risk Management
Parents are often totally unaware of just how often their children take risks and just how good they are at managing that risk. Researchers found children indulge in a great deal of thoughtful and considered risk taking that is invisible to adults. On average the researchers found that while children may make misjudgments, they do not, as is sometimes assumed, 'blindly'throw themselves into risk-taking behaviors. Brain Cells Work Differently Than Previously Thought
Scientists know that information travels between brain cells along hair-like extensions called axons. For the first time, researchers have found that axons don't just transmit information -- they can turn the signal up or down with the right stimulation. This finding may help scientists develop treatments for psychiatric disorders such as depression and schizophrenia in which it is thought that different parts of the brain do not communicate correctly with each other. Wheat Allergy Diet
This chart lists foods that are acceptable and not acceptable for consumption by people with allergies to wheat. Covers beverages, breads, cereals, desserts, and wheat-containing products from other food groups. Also includes wheat substitute measurements and a list of wheat terms to look for when reading food labels. From the Lucile Packard Children's Hospital at Stanford. Computer Graphics Spills From Milk To Medicine
A new computer graphics model capable of generating realistic milk images based on the fat and protein content will likely push the field of computer graphics into the realms of diagnostic medicine, food safety and atmospheric science, according to a new study. [Ironic] An Italian pensioner committed suicide after his wife fell in
Recalling the end of Romeo and Juliet, the 70-year-old man, Ettore, who had sat by his wife's bedside for four months after she slipped into a coma following a heart attack, finally gave up hope and gassed himself in the garage of his family home.Less than a day later, his wife, Rossana, woke up in her hospital bed in Padua and immediately asked for him. A Molecular Basis For Selective Therapeutic Intervention In Alzheimer'
The contribution of University of Aveiro researchers to the complex theme of how 'Cellular stress affects phosphorylation dependent AßPP processing' showed that, even under conditions of cellular stress, one could favour non-toxic AßPP processing by modulating intracellular protein phosphorylation systems and this, in turn, may constitute the basis for selective therapeutic intervention.
Proteins'Role In Coronary Heart Disease
Scientists provided the first large-scale identification of the proteins involved in coronary heart disease. The information will help to better understand the progression of the disease, improve diagnosis, and detect early pathological signs more efficiently. Coronary heart disease, which is characterized by abnormal thickening and narrowing of the blood vessels, is the first leading cause of death in the United States. But what happens inside the cells of these blood vessels is not completely understood.
