The spread of mosquito-borne diseases

The spread of mosquito-borne diseases

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 nonproliferation regime under siege

Throughout the history of humanity, any new technology once invented and developed has diffused across the globe. Moreover, almost all new technologies have had dual use–that is, they could be used to improve the human condition, or they could be used to make the tools of violence even more destructive. We are now facing the inevitable sequel of this evolution as it relates to nuclear weapons. The world simply cannot afford to let nuclear weapons technology and acquisition diffuse all over the globe, considering the enormous destructive potential of even an individual nuclear explosive.
