Turbulence can be found everywhere, from stirring in a teacup to currents in the planetary atmosphere. Predicting such flows is difficult, especially when only incomplete information is available. Now, researchers from Japan and the UK have shown that, in two-dimensional turbulent flows, observing only large-scale motion is sufficient to reconstruct the full flow. Their findings contribute to a deeper understanding of fluid dynamics, with implications for data-driven weather forecasting.

Supercomputer-based simulations reveal the intricacies of sodium-ion clustering and transport in hard carbon nano-pores, report researchers from Science Tokyo. Their results show that a bottleneck effect can lead to the sluggish diffusion of ions in sodium-ion batteries, while also providing useful nanostructural design guidelines to increase the energy density of hard carbon anode. By implementing these insights, the realization of carbon-neutral society can be accelerated.

The University of Trento has demonstrated the existence of an empty lava tube even in the depths of Venus, a planet whose surface and geology have been largely shaped by volcanic processes. The cave was identified through radar data analysis as part of a project funded by the Italian Space Agency. "Our knowledge of Venus is still limited, and until now we have never had the opportunity to directly observe processes occurring beneath the surface of Earth’s twin planet. The identification of a volcanic cavity is therefore of particular importance, as it allows us to validate theories that for many years have only hypothesized their existence," explains Lorenzo Bruzzone, the coordinator of the research, full professor of the University of Trento. "This discovery contributes to a deeper understanding of the processes that have shaped Venus’s evolution and opens new perspectives for the study of the planet," he adds.

Scientists are recruiting adults from across the UK to take part in a groundbreaking trial to accurately track what they eat and drink in their daily lives.
