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.
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.
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.
