Whether you think doomsday will come from the tip of a nuclear warhead, global warming, or killer robots, this installment of Modern Marvels reveals that mankind could be wiped off the face of the Earth by any number of global catastrophes. The Cold War may have ended, but does that mean that we're really safe from the infernal threat of nuclear weapons?

Many people view doomsday as something grandiose, but could nanotechnology produce swarms of microscopic robots that devour every living creature in sight?
