Other recent genetic research has backed up that notion. One study, published in PNAS in 2007 and led by John Hawks, an anthropologist at the University of Wisconsin at Madison, found that some 1,800 human gene variations had become widespread in recent generations because of their modern-day evolutionary benefits. Among those genetic changes, discovered by examining more than 3 million DNA variants in 269 individuals: mutations that allow people to digest milk or resist malaria and others that govern brain development.

It's the very definition of an inconvenient truth...
...available product. Incidentally, according to a psychologist who has worked with it in experiments, it is nearly impossible to rid upholstery of it. Citrus-scented Windex certainly makes for a nicer lab environment, which perhaps has something to do with Liljenquist's continued interest in this line of study. "Research on how to stay on the moral high ground and promote virtue," she says, "is something I find refreshing...

...discovery may prove useful in areas ranging from photovoltaics to recording voltages inside and outside cells, according to the study’s lead author Bozhi Tian, a graduate student in the Department of Chemistry and Chemical Biology. Colleagues in the department yesterday acknowledged the significance of the research...
