The world is living under the threat of nuclear war and a terrifying simulation reveals what would happen if a nuclear bomb went off in a major city.  As well as looking at the destruction, scientists used the computer model to work out how people would behave if the worst-case scenario struck. In the dystopian-like version of The Sims, researchers simulated a nuke exploding in Washington DC. An entire city block was obliterated instantly and buildings blasted for a mile in almost every direction.

Researchers found people who did nothing were most likely to die with nearly 280,000 people killed in just 48 hours.  The simulation was designed to give emergency planners an idea of what chaos would be caused from gridlock, power outages and destroyed communications. Computer scientists from Virginia Polytechnic Institute and State University even created individual personalities for each resident. READ MORE
