The Bulletin of the Atomic Scientists engages science leaders, policy makers, and the interested public on topics of nuclear weapons and disarmament, climate change, and emerging technologies. The Buletin does this through  award winning journal, iconic Doomsday Clock, public access website and regular set of convenings. With smart, vigorous prose, multimedia presentations, and information graphics, the Bulletin puts issues and events into context and provides fact-based debates and assessments. For 70 years, the Bulletin has bridged the technology divide between scientific research, foreign policy and public engagement.

The Bulletin was founded in 1945 by Manhattan Project scientists who “could not remain aloof to the consequences of their work.” The organization's early years chronicled the dawn of the nuclear age and the birth of the scientists’ movement, as told by the men and women who built the atomic bomb and then lobbied with both technical and humanist arguments for its abolition.

Today, the Bulletin is an independent nonprofit 501 (c) (3) organization. With the international network of board members and experts, the Bulletin assess scientific advancements that involve both benefits and risks to humanity, with the goal of influencing public policy to protect the planet and all its inhabitants.
