The NewStatesman dedicate an article on the Virtual Physiological Human, explaining in layman's terms how computer simulations will not only reduce the need to test drugs on animals (and poor bunnies), but will be able to create realistic simulations of human organs and tissues that will open to door to the most revolutionary applications!
"... the data-processing requirements of modern particle physics have driven computing forward so fast, that we now have enough processing power to create realistic simulations of human organs and tissues. Beating human hearts, livers that process virtual chemicals, kidneys that excrete simulated urine and myriad other silicon organs will come together and do away with the need to test drugs on animals."
