A gene that affects the brain's dopamine system appears to have influenced mothers' behavior during a recent economic downturn, researchers say.
At the beginning of the recession that began in 2007, mothers with the "sensitive" version of a gene called DRD2 became more likely to strike or scream at their children, the researchers say. Mothers with the other "insensitive" version of the gene didn't change their behavior.

Arizona's Monument Valley is known for its red sandstone buttes and spires, but now it's notorious for something else: crime. The Navajo Nation is one of the most violent reservations in the country. According to FBI reports, over the past five years, more rapes were reported on the Navajo Nation than in San Diego, Detroit or Denver, among other cities.

The unveiling of "cultured beef," as the burger is branded, was a production worthy of the Food Network era, complete with chatty host, live-streamed video, hand-picked taste testers, a top London chef and an eager audience (made up mostly of journalists). Rarely has a single food gotten such star treatment.
