Gun purchase age limits do little to curb homicides
Age limits for legal purchase of handguns doesn't appear to keep young people from getting firearms, researchers report. Their new study finds that, in the United States, individual state laws barring 18- to 20-year-olds from buying or possessing a handgun make little difference in the rate of homicides involving a gun by people in that age group. "The central issue is that there's a very high de

Disease-spreading ticks keep marching north as weather stays warmer
Ticks are among nature's most hardy survivors. They've been around for at least 100 million years and used to feast on dinosaur blood. Their bodies contain anti-freeze to help them survive cold weather and their two front legs have carbon dioxide and infrared sensors to help detect when a warm-blooded mammal is approaching. Tiny hairs on their legs increases friction and allows ticks to latch onto
