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. Prior research has shown that most modern cities began as small towns and grew over time to become much larger. In this new effort, the researchers wanted to...

A pair of archaeologists, one with Adam Mickiewicz University in Poznań, the other with the University of Warsaw, both in Poland, has found evidence suggesting that rock carvings found in a southern part of Peru may have been inspired by people singing while consuming hallucinogenic plants.
