The iconic Doomsday Clock remains poised at five minutes until midnight, the Science and Security Board of the Bulletin of Atomic Scientists announced today (Jan. 14). The clock is no doomsday device â rather, it's a visual metaphor for the danger of a "civilization-threatening technological catastrophe." Every year, the board analyzes international threats, particularly nuclear arsenals and climate change, and decides where the minute hand on the Doomsday Clock should rest. The Doomsday Clock is the invention of the Bulletin of Atomic Scientists, a publication started by some of the researchers who worked on the atomic bomb. The wife of one of these researchers, Martyl Langsdorf, was a painter.
