Bulletin of the Atomic Scientists

In 1945, the first newsletter, Vol. 1, No. 1, was published that would become the The Bulletin of the Atomic Scientists, later noted for its Doomsday Clock on the cover. After the first Soviet hydrogen bomb test on 12 Aug 1953, to represent the urgency to avoid humanity's catastrophic destruction, the hands of the clock on the Sep 1953 cover (Vol. 9, No. 7) were advanced to two minutes to midnight—the closest to nuclear Doomsday (midnight) they have ever been. The minute hand has been moved backward and forward over the years representing lessening or increasing urgency of problems regarding world's nuclear proliferation, and, the more recent additional concerns for climate change and bioweapons.
