West Nile virus has recently emerged as a health threat to the North American population after the initial disease outbreak in New York City in 1999. Since then, West Nile virus has spread widely and quickly across North America. In this study researchers developed models of mosquito populations and created a spatial risk assessment of West Nile virus prior to its arrival in British Columbia by creating a raster-based mosquito abundance model using basic geographic and temperature data. The result of the spatially-explicit mosquito abundance model indicates that the Okanagan Valley, the Thompson Region, Greater Vancouver, the Fraser Valley and southeastern Vancouver Island have the highest potential abundance of the mosquitoes. After including human population data, Greater Vancouver, due to its high population density, increases in significance relative to the other areas. Creating a raster-based mosquito abundance map enabled researchers to quantitatively evaluate West Nile virus … [Read more...] about A spatial risk assessment of West Nile virus in British Columbia

image by Mike Rosulekhere to benefit NCSE It's a classic question: if Charles Darwin had known about Gregor Mendel's genetic research, would Darwin have realized it was the missing piece he needed to explain how individual variation was inherited and selected? Was it simply bad luck that Darwin never stumbled on the right experiments? Or was Darwin so constrained by his own perspective on inheritance that he couldn't have seen the importance of Mendel's work, even if he had known about it? Jonathan Howard has written an intriguing overview of this question. He argues that Darwin was on the brink of discovering Mendel's Laws several times - if he had only been looking for them. Darwin, it turns out, did have data much like Mendel's, from Darwin's own plant breeding experiments: In one especially poignant case , working with the recessive character of radially symmetrical (peloric) flowers of Antirrhinum (Figure 4), Darwin came close to the kind of result that might have ended with a … [Read more...] about Why didn’t Darwin discover Mendelian genetics first?
(CNN)As with any medication, statins can come with side effects. Statins, drugs typically used to lower cholesterol, are relatively safe for most people. When they are taken specifically to prevent cardiovascular disease, a new study suggests, the side effects just might outweigh the benefits, depending on your age, sex and the specific statin you're taking. For instance, atorvastatin and rosuvastatin provided cardiovascular benefits at a lower 10-year risk than simvastatin and pravastatin, according to the study. Overall, the benefit of statins may come with higher 10-year risks for cardiovascular disease than are reflected in most guidelines, according to the study, published Monday in the medical journal Annals of Internal Medicine. The finding raises the question: Are statins overprescribed for the prevention of cardiovascular disease? Read More The study analyzed the benefits and risks only when using statins for the primary prevention of cardiovascular disease, including … [Read more...] about Why the risks and benefits of statins are so complex
Immigrants coming to the United States from Southeast Asia experience a rapid "Westernizing" of the bacteria in their guts that could explain their rising rates of obesity and related diseases. University of Minnesota researchers discovered the pattern by analyzing the digestive bacteria of 514 Hmong and Karen women — some still living in Southeast Asia, some who recently arrived in the Twin Cities, and some who were U.S.-born children of immigrants — and comparing them with the bacteria of 36 white Minnesota women. Six to nine months after arriving in the U.S., the immigrant women had a drop in the number and diversity of their gut bacteria — which are essential for digestion, and for immune system health — according to the study, which was published in Cell, an influential scientific journal. "Immigrants begin losing their native microbes almost immediately after arriving in the U.S., and then acquire alien microbes that are more common in European-American … [Read more...] about American diet changes gut bacteria of immigrants
