In the "butterfly effect," an insect can flap its wings and create a microscopic change in initial conditions that leads to a hurricane halfway around the world. This chaos is seen everywhere, from weather to labor markets to brain dynamics. And now, in the journal Chaos, researchers explored how to turn the twisting, fractal structures behind the science into jewelry with 3D printing. The jewelry shapes are based on the Chua circuit, a simple electronic system that was the first physical, mathematical, and experimental proof of chaos.

Although gun violence is a challenging problem in the U.S., few in-depth statistical studies have been carried out on a state-by-state basis. In Chaos, mathematicians provide a thorough analysis of gun violence incidents from early 2018 to mid-2022 in all 50 states and compare their results to historical events during that period. The investigators analyzed data provided by the Gun Violence Archive, using time series analysis, paying particular attention to the summer of 2020 when the national media reported widespread violence due to a combination of COVID-19 shutdowns, the murder of George Floyd, and subsequent protests and unrest.

Scientists from the Nikol'skii Mathematical Institute of RUDN University built a mathematical model that describes the self-sustaining propagation of virus concentration waves – autowaves – in a tissue or cell culture, taking into account their competition for resources, that is the infected cells. The authors applied the constructed model to study variants of the new coronavirus, Delta and Omicron. It turned out that the autowave with the higher speed of spatial propagation wins, while the slow autowave dies. The studied processes relate to the competition and evolution of viral strains in the upper respiratory tract in vivo. In addition, the proposed approaches can be used when creating new methods for studying viruses in vitro.

The Journal of Mathematical Physics has recognized Sam Collingbourne as the winner of its 2021 Young Researcher Award. His work on the stability properties of space-times in high dimensions culminated in the winning publication, "The Gregory-Laflamme instability of the Schwarzschild black string exterior." The judges selected Collingbourne from a pool of JMP authors and the prize includes $3,000. Collingbourne explores solutions to the Einstein equation, which relates the curvature and geometry of space-time to the matter content in space-time.
