Scientists search for source of creativity
USC researchers are working to pin down the exact source of creativity in the brain -- and have found that the left hemisphere of your brain, thought to be the logic and math portion, actually plays a critical role in creative thinking.

No evidence that higher regional health care costs indicate inappropriate care, study shows
There is no solid evidence to support the widely held belief that regions of the United States that spend more on health care and have higher rates of health care use deliver more unnecessary care to patients, or that low-cost areas deliver higher quality and more efficient care.

Scientists study human diseases in flies
At the ongoing Genetics Society of America's 53rd Annual Drosophila Research Conference in Chicago, several scientific investigators shared their knowledge of some of the genetic diseases that have counterparts in the well-studied model organism, fruit fly, including ataxia-telangiectasia, a neurodegenerative disorder; Rett Syndrome, a neurodevelopmental disorder; and kidney stones, a common health ailment.

Over 20 million individuals infected with hepatitis E in Asia and Africa
New research funded by the World Health Organization estimates that 20.1 million individuals were infected with hepatitis E virus genotypes one and two across nine world regions in 2005. According to findings available in the April issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases, there were 3.4 million symptomatic cases, 70,000 deaths, and 3,000 stillbirths from HEV that year in countries throughout Asia and Africa.

A new approach to treating type I diabetes? Gut cells transformed into insulin factories
A study by Columbia researchers suggests that cells in the patient's intestine could be coaxed into making insulin, circumventing the need for a stem cell transplant. Until now, stem cell transplants have been seen by many researchers as the ideal way to replace cells lost in type I diabetes and to free patients from insulin injections.

Research from the University of Warwick suggests suicide rates are much higher in Protestant areas than Catholic areas.

Embryonic stem cells shift metabolism in cancer-like way upon implanting in uterus
When an embryo implants in the uterus, the low-oxygen environment provokes some of its cells to shift to a sugar-busting metabolism. In cancer cells, the same shift releases fuel and materials for rapid tumor growth and division. In the embryo, the shift prepares for dramatic growth and formation of layers that later become organs. The researchers also saw a mitochondrial downshift linked to aging and disease controlling normal embryonic development. It may protect cells that later become eggs or sperm from oxidant damage.

Walking may lessen the influence of genes on obesity by half
