The American Bomb was the white men’s bomb. A secure future demands that everyone have a seat at the table.

Newly declassified documents reveal details of the Nuclear Non-Proliferation Treaty negotiations and highlight the potential for disarmament-based global security.

Incorporating the Madden Julian Oscillation into weather forecasting could give communities more time to prepare for extreme precipitation.

A high-tech project to eliminate malaria from Africa requires the consent of local people. But how do you gain their consent when they have little idea what you’re talking about?

There are approximately 2,500 mosquito species in the world, but a mere fraction of them feed on human blood. Of this fraction, only the females are vampires, as they require blood to nourish their eggs. When she's ready to lay these eggs, which usually number in the hundreds, the female typically does so on a small, still body of water. In some mosquito species, she creates little rafts for the eggs. They float until they hatch as tiny larvae a few days later. Like butterflies, they eventually turn into pupae, which ultimately metamorphose into the insects we know.

The television drama 24 is currently portraying one of the most frightening and dangerous terrorist scenarios possible--an anti-American terrorist group with radioactive fissile materials intent on detonating a "dirty bomb" in New York City to render it uninhabitable for decades to come. Jack Bauer, the show's intrepid hero, is trying to track down the terrorists and capture the fissile materials before the terrorists have a chance to blow them up. Although television dramas often engage in hyperbole, the basic theme of this terrorist scenario is very real.

The idea that intervention will make America safer is wrong-headed.

Few things have gone right since the 2010 Non-Proliferation Treaty Review Conference called for a 2012 meeting to discuss establishing a WMD-free zone in the Middle East. Evidence of nuclear weapons-related research in Iran has continued to mount, putting the world, and particularly Israel, on edge. By now, the enthusiasms of 2010 seem almost quaint.

As the plausible military rationales for nuclear weapons continue to deteriorate in the aftermath of the Cold War, political and psychological rationales for nuclear weapons -- like providing reassurance to US allies -- are increasingly viewed to be just as important as deterrence.

It’s sometimes forgotten that in March 2013 the head of America’s Pacific Command said the top security threat in the region was global warming. Simon Winchester thinks it’s worth remembering.

Despite being an important step toward disarmament, no new zone free of nuclear weapons has entered into force since 2009—the longest stretch ever without a pact.

To beat back chikungunya, dengue, and yellow fever, human behavior has to change.

It is a fact that nuclear terrorism is a global threat and has become a worldwide concern. But what is particularly frightening is that there is no clearly defined plan for securing all nuclear materials. According to the Nuclear Threat Initiative's (NTI) Nuclear Material Security Index, there is no global consensus about what steps matter most in achieving nuclear security.

As we work to arrest global warming, we must also mitigate the food security problems it will cause.

The US withdrawal from the Paris Climate Agreement leaves the world billions short on funds to help countries curb carbon emissions. Cities and states can help make up the difference.
