Parents prefer teachers who make their children happy even more than those who emphasize academic achievement, a new study shows. When requesting a teacher for their elementary school children, parents are more likely to choose teachers who receive high student satisfaction ratings than teachers with strong achievement ratings. Coal Tar-based Pavement Sealers Implicated As A Source Of Urban Water
A water pollution episode in Austin, Texas, is raising questions about the environmental impact of coal tar-based sealants used on thousands of parking lots throughout the United States, according to an article in Chemical and Engineering News. Allergic Reactions To Gadolinium-based Contrast Agents Are Rare, Study

Cancer Stem Cells Spur Glioma Angiogenesis, Could Hold Key To Brain Tu
Stem cell-like glioma cancer cells that share many characteristics with normal stem cells propel the lethal growth of brain cancers by promoting tumor blood vessel formation, and may hold the key to treating these deadly cancers, a research team reported in the August 15th issue of Cancer Research. Agricultural Soil Erosion Not Contributing To Global Warming, Study Sh
Agricultural soil erosion is not a source of carbon dioxide to the atmosphere, according to research in Science. Erosion actually leads to more carbon being removed from the atmosphere than is emitted, creating what can be described as a 'sink'of atmospheric carbon. Ground Frequency Recovery After Strong Earthquakes
Because earthquake shock sometimes decreases the frequency at which the ground vibrates, especially at soft soil sites, the strength of strong ground motion during an earthquake is an important characteristic that can affect the degree to which geological structures and buildings collapse. Although most research focuses on the reduction in peak frequency of site response caused by strong ground motion, Sawazaki, et al. sought instead to document peak frequency recovery following large earthquakes. Genetic Cause Of Speech Defect Discovered
