Fluid dynamics is the study of the motion of liquids, gases and plasmas. Flow is dependent on the intrinsic properties of the matter itself, such as compressibility, viscosity and density. Example systems are a liquid flowing through a pipe or capillary, air moving across an aeroplane wing, and plasma motion in a stars magnetic field.
Theoretical studies discover quantum momentum tunnelling between liquid flows separated by nanometre-thick graphene layers via the interaction between molecular dipole excitations and plasmons.

Collectives of self-driven particles display a plethora of behaviours that are gradually being discovered. Experiments with rotating particles in intermediate Reynolds flow now harness a mostly unexplored inertial regime for synthetic active matter.
Macroscopic fluid dynamics is usually thought to emerge from vast numbers of microscopic particles. Now, fluid-like behaviour has been observed in systems of startlingly few atoms.
Navigating medical microrobots through intricate vascular pathways is challenging. AI-driven microrobots that leverage reinforcement learning and generative algorithms could navigate the body’s complex vascular network to deliver precise dosages of medication directly to targeted lesions.
