UrduScientists in China have developed a modeling technique to study urban traffic flows and show that their model can be used to find previously unknown bottlenecks. The model uses a modified form of percolation theory, and the investigators considered the existing road network and population distribution in Shanghai.

Fighting Intolerance with Physics
In a world experiencing growing inequality and intolerance, tools borrowed from science and mathematics could be the key to understanding and preventing prejudice. In Chaos, Luis A. Martinez-Vaquero applies evolutionary game theory, which combines techniques from economics and biology, and complex system analysis to investigate the relationship between inequality and intolerance. He found that inequality boosts intolerance and that redistribution of wealth can prevent its infectious spread.
American Institute of Physics Announces 2020 Science Communication Award Winners
The American Institute of Physics recognizes the winners of the 2020 Science Communication Awards for their topical works on reshaping our world, recognizing forgotten women in science, searching for knowledge, and hunting down black holes. The 2020 winners are Susan Hockfield, Joshua Sokol, Curtis Manley, and Catalyst.
Critical Transition Theory Shows Flickering in Heart Before Atrial Fibrillation
Atrial fibrillation ranks among the most common heart conditions, and episodes are difficult to predict. Researchers have proposed a way to define cardiac state and have studied the dynamics before the cardiac rhythm changes from normal sinus to AF rhythm and vice versa. The work, appearing in Chaos and based on critical transition theory, looks to provide an early warning for those with paroxysmal atrial fibrillation with potential implications for future wearable devices.
Correlations in COVID-19 Growth Point to Universal Strategies for Slowing Spread
Many months since the first COVID-19 outbreak, countries continue to explore solutions to manage the spread of the virus. Chaos theory researchers analyzed the growth of confirmed cases across four continents to better characterize the spread and examine which strategies are effective in reducing it, and their results, published in Chaos, found the virus commonly grows along a power law curve.
