The New York Times bestselling edge-of-your-seat non-fiction thriller, perfect for readers of American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer by Kai Bird and Midnight in Chernobyl by Adam Higginbotham.

The role of health professionals In January 2023, the science and security board of the Bulletin of the Atomic Scientists moved the hands of the doomsday clock forward to 90 seconds before midnight, reflecting the growing risk of nuclear war.1 In August 2022, the UN secretary general, António Guterres, warned that the world is now in “a time of nuclear danger not seen since the height of the Cold War.”2 The danger has been underlined by growing tensions between many nuclear armed states.13 As editors of health and medical journals worldwide, we call on health professionals to alert the public and our leaders to this major danger to public health and the essential life support systems of the planet—and urge action to prevent it. Current nuclear arms control and non-proliferation efforts are inadequate to protect the world’s population against the threat of nuclear war by design, error, or miscalculation. The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) commits each of the 190 participating nations

Fearful that the Able Archer 83 exercise was a cover for a NATO nuclear strike, the U.S.S.R. readied its own weapons for launch

Land-based nuclear weapons are world-ending accident waiting to happen, and completely superfluous to a reliable deterrent.

If the system can’t contact military leaders, it checks for signs of a nuclear strike. Should its computers determine that an attack occurred, it would automatically launch all remaining Soviet weapons at targets across the northern hemisphere. As in the film, the Soviet Union long kept Dead Hand completely secret, eliminating any strategic benefit, and rendering it a pointless menace to humanity. You might think the United States would have a more sensible nuclear launch policy. You’d be wrong.

Humanity is now a ‘geological superpower’ and declaring a new epoch is critical to tackling its impact, scientists say

As the world remembers Hiroshima, it must also recommit to the increasingly fragile non-proliferation treaty. The alternative is unthinkable

Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth’s climate, limiting terrestrial and aquatic food production. Here, we use climate, crop and fishery models to estimate the impacts arising from six scenarios of stratospheric soot injection, predicting the total food calories available in each nation post-war after stored food is consumed. In quantifying impacts away from target areas, we demonstrate that soot injections larger than 5 Tg would lead to mass food shortages, and livestock and aquatic food production would be unable to compensate for reduced crop output, in almost all countries. Adaptation measures such as food waste reduction would have limited impact on increasing available calories. We estimate more than 2 billion people could die from nuclear war between India and Pakistan, and more than 5 billion could die from a war between the United States and Russia—underlining the importance of global cooperation in preventing nuclear war.

A Russian former foreign minister has joined a call for all sides in the Ukrainian war to return to diplomacy and so reduce “the dramatically elevated risk” of a nuclear conflict. The appeal co-authored by Prof Igor Ivanov, now the president of the Russian International Affairs Council, may be a sign that some in the Russian foreign policy establishment believe that pursuing a purely military solution in Ukraine is a strategic mistake.

On Sunday, Vladimir Putin ordered his nuclear deterrent forces to be placed on a “special regime of combat duty”. The Russian defence minister, Sergei Shoigu, has now clarified what this meant: the increased manpower devoted to Russia’s strategic nuclear triad: land-based strategic nuclear rocket forces, sea-based nuclear deterrents in the northern and Pacific fleets and its fleet of long-range strategic bomber aircraft that can carry nuclear weapons.

While 32 countries generate atomic energy, nine have nuclear weapons and seven countries have both.

Scientists are hopeful that the National Ignition Facility’s recent success will advance understanding of thermonuclear reactions.

The U.S. nuclear power regulator last month suspended the shipment of radioactive materials and a hydrogen isotope used in reactors to China's largest state-owned nuclear company, CGN, reflecting Washington's concerns about the country's buildup of atomic weapons.
