Indigenous hunters have positive impacts on food webs in desert Australia

Sun, 02/17/2019 - 2:25pm
Australia has the highest rate of mammal extinction in the world. Resettlement of indigenous communities resulted in the spread of invasive species, the absence of human-set fires, and a general cascade in the interconnected food web that led to the largest mammalian extinction event ever recorded. In this case, the absence of direct human activity on the landscape may be the cause of the extinctions, according to an anthropologist.

Genetic vulnerability to menthol cigarette use

Fri, 02/15/2019 - 4:20pm
A genetic variant found only in people of African descent significantly increases a smoker's preference for cigarettes containing menthol, a flavor additive. The variant of the MRGPRX4 gene is five to eight times more frequent among smokers who use menthol cigarettes than other smokers. The multi-ethnic study is the first to look across all genes to identify genetic vulnerability to menthol cigarettes.
