Researchers at North Carolina State University have created a wearable patch that can detect hazardous gaseous, aerosolized, and aqueous environmental toxins and notify wearers by vibrating against their skin. For this work, the researchers created a square patch slightly smaller than a driver’s license. The patch contains a microcontroller that serves as the patch’s brain; […]

One summer day in 1941, a British radio operator was monitoring German military frequencies and heard something unexpected in her headphones. A later report called it “strange new music.” Sounding unlike the familiar Morse dit-dit-dah of enciphered messages sent over the German Enigma network, the “new music” was a rhythmic warble of binary teletype code being transmitted at […]
