A newly released study finds that African ancestry is associated with triple-negative breast cancer, a more aggressive type of cancer that has fewer therapy options. Scientists at the University of Michigan Comprehensive Cancer Center observed that, among women with breast cancer, 82 percent of African women were triple negative, 26 percent of African-Americans were and 16 percent of white Americans were........

To children, the summer slide means water, garden hoses and slippery plastic sheets. To teachers, the "summer slide" is the noted decrease in reading skills after a vacation without books. University of Tennessee, Knoxville, faculty members Richard Allington and Anne McGill-Franzen have completed a three-year study showing a significantly higher level of reading achievement in students who received books for summer reading at home. Allington and McGill-Franzen are both professors of education; McGill-Franzen is also director of the Reading Center in the College of Education, Health and Human Sciences........

Chaos theory help predict heart attacks
Fri, 23 Jul 2010 13:06:31 GMT
Chaos models may someday help model cardiac arrhythmias -- abnormal electrical rhythms of the heart, say scientists in the journal CHAOS, which is published by the American Institute of Physics. In recent years, medical research has drawn more attention to chaos in cardiac dynamics. Eventhough chaos marks the disorder of a dynamical system, locating the origin of chaos and watching it develop might allow scientists to predict, and maybe even counteract, certain outcomes........

Key pathway in end-stage prostate cancer blocked
Fri, 23 Jul 2010 13:06:31 GMT
Prostate cancer advances when tumors become resistant to hormone treatment, which is the standard therapy for patients, and begin producing their own androgens. Scientists at UT Southwestern Medical Center have observed that blocking one of the enzymatic steps that allow the tumor to produce androgens could be the key in halting a tumor's growth........

The way a family interacts can have more of an impact on a child's predicted school success than reading, writing or arithmetic, as per a University of Notre Dame study published recently in the Journal of Child Development. University of Notre Dame Professor of Psychology Mark Cummings and his colleagues at the University of Rochester studied the relationship patterns of some 300 families (with six year-olds) over the course of three years, and found distinct family-school connections. Specific family "types" emerged as predictors of school success:.......

Protection against ticks that carry Lyme disease
Fri, 23 Jul 2010 13:06:31 GMT
Research on the population of black-legged ticks, which can transmit Lyme disease from host animals to humans, reinforces that it is important to take preventative measures when spending time outdoors. University of Illinois graduate student Jennifer Rydzewski conducted a four-year survey of black-legged ticks (also known as deer ticks), their host animals, and their habitat preferences in Cook, Lake, DuPage, and Piatt Counties. The survey confirmed the presence of ticks in all four counties and ticks carrying Lyme disease in Piatt County. Higher numbers of ticks were found along the Des Plaines River corridor........
