New model of ocean waves sheds fresh light on the spread of microplastic pollution
Nature is always more complicated than the models we use to describe it. Ocean waves, for example, are constantly evolving. They grow when wind transfers kinetic energy to the water’s surface. They interact with each other in highly nonlinear ways. And once the wind dies down, their internal viscosity makes them dissipate away to nothing, leaving behind a surface as flat as glass.

Dynamically emergent correlations
In this perspective article, we discuss the scenario of dynamically emergent correlation (DEC) arising in classical and quantum noninteracting systems when they are subjected to a common fluctuating stochastic environment. The key property of such systems is that the strong correlations between different particles emerge from the dynamics and not from built-in interactions. In many cases, these strong correlations persist even at long times in the stationary state.

Multiband omnidirectional ventilation acoustic barrier based on subwavelength gradient microcavity
Constructing artificial microstructural units that preserve free airflow while achieving efficient low-frequency sound insulation (<2000 Hz) remains a significant challenge for acoustic engineering applications. Here, we proposed an angularly gradient labyrinthine unit cell with gradually varying azimuthal spatial dimensions, enabling multiband sound insulation while maintaining ventilation…
