Modeling urban growth shows that cities develop in ways similar to cancerous tumors

A team of environmental engineers and city planners from University College London, the University of Sydney, and École Polytechnique Fédérale de Lausanne has discovered that cities grow in ways similar to the development of cancerous tumors. In their paper published in Journal of the Royal Society Interface, the group used mathematical models to explain how the city of London grew into its current state, and then applied the models to Sydney, Australia.
