Doomsday Clock set: '90 seconds to midnight'

Nuclear risk, biological threats, climate change and disruptive technologies are cited by the Bulletin of Atomic Scientists as reasons for moving the Doomsday Clock to 90 seconds to midnight, signaling a time of unprecedented danger. "Founded in 1945 by Albert Einstein and University of Chicago scientists who helped develop the first atomic weapons in the Manhattan Project, the Bulletin of the Atomic Scientists created the Doomsday Clock two years later, using the imagery of apocalypse (midnight) and the contemporary idiom of nuclear explosion (countdown to zero) to convey threats to humanity and the planet," according to the Bulletin of Atomic Scientists.
