Declining birth rates and rising life expectancy are reshaping the size and age structure of families worldwide. A recent study reveals that the question is not only whether these changes will occur, but also how quickly they will unfold.

Can we predict Steph Curry’s next move on the court? Last year, Boris Barron started at MPIDR as a research scientist in the Migration and Mobility Department. He is a physicist and specializes in modeling complex systems. While at Cornell University, he and his colleagues developed a methodology to analyze detailed positional information of basketball players in NBA games. Their approach adapted a physics-based approach, Density Functional Fluctuation Theory (DFFT), to provide a general framework to infer subtle aspects of the game. More
