The U.S. military has a new weapon: An "active denial system" that "shoots a beam that makes people feel as if they are about to catch fire." That makes me smile. This "ray gun" uses a form of microwave radiation called electromagnetic millimeter waves that are capable of penetrating a very thin layer of human skin. The penetration heats the skin up to about 130°F, making it extremely uncomfortable but completely non-lethal and non-injurious. God bless America. (via Mental Floss) #science
