The hibakusha (survivors) of the 1945 bombings have been among the most tireless campaigners for the treaty. The Japanese government, however, has not supported it.
The threat of nuclear war has not diminished, despite the lessons learned from the Hiroshima and Nagasaki bombings in 1945.
As Pope Francis becomes the first pontiff in the nuclear era to call for total disarmament, all of us – whether secular or religious – can engage through creative and proactive moral responsibility.
We might have had a glimpse of new ways of urban living, but history offers a note of caution. Lasting change depends on us applying technology and taking deliberate action to seize this opportunity.
With the risk of a nuclear conflict seeming higher than ever, how much do EU citizens really know about nuclear weapons and their use? A new survey provides striking answers.
According to most physicists, there is no safe dose of radiation. So why would the EPA consider saying otherwise? Who stands to gain if the EPA declares low-dose radiation harmless?
The Trump administration shelved its plans for a 'bloody nose' attack while the Olympics in South Korea were under way. With the games over, it's time to consider the consequences of a strike.

Any nuclear weapon exchange or major nuclear plant meltdown will immediately lead to a global public health emergency. What can we learn from past events to help prepare?
The average age of survivors is now 80. In five years, very few of these first-hand witnesses will be around to remember the event. Many of their stories are in danger of being lost forever.
In the wake of the atomic bombs, a number of Japanese animators would question mankind's relationship with technology.
News of the Hiroshima bombing spread quickly to the US public but, thanks to science fiction writers, atomic bombs were discussed more before the war began than during it.
John Hersey's article Hiroshima (1946) is seminal in historical and literary terms: the shocking realities of the atomic bomb demanded a new way of writing.
Today's nuclear arsenals are so powerful that dropping a Hiroshima-size bomb every two hours for 70 years would not exhaust their destructive capacity. The global disarmament regime is broken.
The first atom bomb test seventy years ago today marks the start of a change in Americans' thinking about radiation. On balance, our nuclear anxieties endure today.
