Pollutants in some urban areas increase Parkinson’s disease risk
High levels of manganese and copper pollution in urban areas are linked to increased risk of Parkinson’s disease, according to a large-scale analysis of urban pollution and Parkinson’s incidence in the United States. Scientists at Washington University School of Medicine in St. Louis found that people living in areas with higher levels of manganese pollution had a 78 percent greater risk of Parkinson’s disease than those living in areas free of such pollution.
Founder Events and Speciation: Mayr’s Most Misrepresented and Misunderstood Legacy to Speciation Theory
An evolutionary and population biologist at Washington University in St. Louis says that Ernst Mayr’s theory of genetic revolution has been illustrated nicely in recent years in human genetic epidemiology and population biology studies. Alan R. Templeton, Ph.D., Washington University professor of biology in Arts & Sciences, said that there is an extensive documentation of genetic interaction over the past few years including his own genetic epidemiology studies of coronary artery disease (CAD).
