When politicians use selected modelling results to justify their decisions on contentious projects like Melbourne’s North East Link, the credibility of transport models suffers by association. Vic Govt/AAP

The problem with transport models is political abuse, not their use in planning

Transport modelling has been tarnished by its use to justify the predetermined projects politicians favour. But, if used more transparently, it’s a valuable tool for planning our future cities.
Whether it’s birds in a flock or drivers in traffic, agent-based modelling can describe complex phenomena by applying a simple set of rules to each individual’s behaviour. Barry Sweet/EPA

Traffic is complex, but modelling using deceptively simple rules can help unravel what’s going on

By identifying and applying the key rules governing the behaviour of each individual, agent-based modelling offers insights into complex phenomena like traffic jams and flocking.

How AI is helping to predict and prevent suicides

From predicting suicide risk to chatbot therapy, artificial intelligence is all the rage in suicide prevention. The question is, can it really work?
If more people live in the Adelaide Hills, they are more likely to be exposed to bushfires. David Mariuz/AAP

Natural hazard risk: is it just going to get worse or can we do something about it?

What decisions can we make today to reduce the future risk of hazards like floods and fire? Particularly in a time of climate change, modelling various plausible futures helps us plan for uncertainty.
People currently speak 7,000 languages around the globe. Michael Gavin

Why do human beings speak so many languages?

There’s little research into origins of the geographic patterns of language diversity. A new model exploring processes that shaped Australia’s language diversity provides a template for investigators.

Welcome to Lab 2.0 where computers replace experimental science

Developing new technologies requires time-consuming, expensive and even dangerous experiments. But now we can carry out many experiments entirely on computers using modelling.
Every living organism needs the same five basic processes – and we can now model ecosystems on them. erban/Flickr

Life boils down to five ‘rules’ … or so says the Madingley Model

It may sound overly simple, but just five processes can define us as animals: eating, metabolism, reproduction, dispersal and death. They might not seem like much, but, thanks to a mathematical model from…
From geysers to tectonic plate movements, corn syrup has the answers. Trey Ratcliff

4D model solves Yellowstone’s geographical mysteries

A decade ago, with Ross Griffiths of the Australian National University, we aimed to build a 4D model which could replicate the Earth’s tectonic processes. Now, our research has helped us understand how…
The Blue Marble: who’s pulling the strings here? NASA

Even if Earth changes, life will continue with or without us

It seems somewhat eccentric if not a little absurd to suggest that a planet is a living thing. Earth has life on it, but it’s not a biological organism. Any theory or argument which concludes that the…
