UPDATE: The BAS did indeed move the Doomsday Clock forward, by one minute. It now reads five minutes to midnight.
Tick, tick, tick... doom. Listen closely this afternoon and you may hear the ominous whirrings of the Doomsday Clock, counting us ever closer to mankind's certain end.
The clock, invented in 1947 in the wake of the Hiroshima and Nagasaki bombings, tells the world – symbolically – how close it is to total nuclear destruction.
Initially set at seven minutes to midnight (i.e. wipe-out), the clock currently reads 11:54 PM. Later today, LiveScience reports, the Bulletin of Atomic Scientists (BAS) will decide whether to adjust it to reflect current threats to humankind.
