Newly identified genetic variations may affect breast cancer risk

Researchers have identified genetic variations in a region of DNA that may be associated with risk for breast cancer. Women with the variation have a 1.4 times greater risk of developing breast cancer compared to those without this variation. The study is one of several genome-wide association studies looking for breast cancer genes to be published this year by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and their colleagues. more

Study uncovers cause of flu epidemics

The exchange of genetic material between two closely related strains of the influenza A virus may have caused the 1947 and 1951 human flu epidemics, according to biologists. The findings could help explain why some strains cause major pandemics and others lead to seasonal epidemics. more  

Genes hold the key to how happy we are, scientists say

Happiness in life is as much down to having the right genetic mix as it is to personal circumstances according to a recent study. more

Blueberry and green tea containing supplement protects against stroke damage  

A unique dietary supplement called NutraStem ® has been shown to have beneficial effects following experimental stroke. A nutritional supplement product, NutraStem also known as NT-020, is a proprietary formulation of blueberry, green tea, vitamin D3 and carnosine extracts- a combination of nutritional ingredients thought to be potent in protecting against brain damage. more

Irritating smells alert special cells, NIH-funded study finds 

If you cook, you know. Chop an onion and you risk crying over your cutting board as a burning sensation overwhelms your eyes and nose. Scientists do not know why certain chemical odors, like onion, ammonia and paint thinner, are so highly irritating, but new research in mice has uncovered an unexpected role for specific nasal cavity cells. more

Testosterone could guard against eating disorders

Testosterone appears to protect people against eating disorders, providing further evidence that biological factors – and not just social influences – are linked to anorexia and bulimia, according to new research findings at Michigan State University. more
