A research team led by Professor Heonsang Lee at Dong-A University in South Korea claims to have resolved a puzzle in fluid dynamics that has stood for about 130 years: whether interfaces exist between miscible fluids, which mix freely with one another. The finding, reported in Korean media under the physics label, sheds light on boundary behavior between fluids that were long thought to have no interface.
- 2Juno reveals Earth-sized cyclones swirling at Jupiter's north pole▼Recent observations from the Juno spacecraft reveal the complex fluid dynamics governing Jupiter's north pole, character
New observations from NASA's Juno spacecraft show the intricate fluid dynamics at Jupiter's north pole, where a stable ring of circumpolar cyclones has persisted. Each storm system is nearly the size of Earth, and the findings highlight how these massive atmospheric vortices remain organised without merging, deepening scientists' understanding of giant planet weather.
- 3Scientists Use Bottle Acoustics to Steer Microrobots●Driving Robots with Acoustic Resonance Blow across a glass bottle at the right flow speed, and you’ll excite Helmholtz r
Researchers have developed a new method for controlling microrobots using Helmholtz resonance — the acoustic effect produced when you blow across a glass bottle's neck. By miniaturizing the effect, they can drive the tiny robots with sound generated by airflow. The work was shared with flow visualization imagery, and physics and fluid dynamics enthusiasts are discussing its potential applications.

The American Physical Society is highlighting work on quasicrystalline water waves, in which fluid surface waves are arranged in quasi-periodic patterns analogous to the atomic structures of quasicrystals. The demonstration extends quasicrystal physics from solid materials into fluid dynamics, offering a new way to study wave interference and symmetry in liquids.
- 5NASA's Perseverance rover finds groundwater, lakes and hot fluids on Mars▼NASA's Perseverance Mars rover finds groundwater, lakes, and hot fluids in one place
NASA's Perseverance Mars rover has found evidence of groundwater, lakes, and hot fluids coexisting in a single location on the Red Planet. The finding points to a dynamic ancient environment where liquid water and geothermal activity overlapped, with implications for Mars' past habitability.
- 6X-ray microscopy reveals flow behaviour in nanoparticle suspensions▼Multiscale transitional flow in anisotropic nanoparticle suspensions revealed by time-resolved X-ray scatter microscopy
Researchers have used time-resolved X-ray scatter microscopy to reveal multiscale transitional flow in anisotropic nanoparticle suspensions, according to a study published in Nature. The technique captures how these suspensions behave across different length and time scales as they transition between flow regimes. Findings could inform work on complex fluids in materials science and industrial processing.
- 7New Quantum Algorithm Targets Fluid-Flow Bottleneck●New Quantum Algorithm Targets Bottleneck in Fluid-Flow Modeling
Researchers have introduced a new quantum algorithm aimed at a key bottleneck in fluid-flow modeling, a computationally intensive problem in physics and engineering. The development suggests quantum computing could eventually speed up simulations of turbulence and fluid dynamics that strain classical supercomputers. Details on the team behind it and practical timelines remain limited.
