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.
Patches of turbulence in straight pipe flow (‘puffs’) display collective dynamics that is not well understood. Now, this dynamics is shown to harbour a phase transition of the directed percolation type, displaying jamming at high puff density.
Emulsions underpin a wide range of important natural phenomena and many technological applications. However, it remains challenging to create emulsion droplets with specific internal structures. Now, a method has been developed to create macromolecular emulsions with custom architectures by applying non-equilibrium thermodynamic principles to condensate formation.
Anderson localization is a linear phenomenon, with ongoing debate about the impact of nonlinearity. This study shows that nonlinearity strengthens the localization of surface-gravity waves in a canal with a random bottom through experimental measurements and numerical simulations.
Diffusiophoresis and diffusioosmosis govern the dynamics of catalytically active colloids. Here, the authors show that the competition between these effects can control the propulsion direction of active colloidal rafts composed of a central apolar particle and several shells of passive ones.
Acute myocardial infarction has become a public health disease threatening public life safety. Here, authors propose a BAS Mem with an ultra-high rectification coefficient, replacing the conventional chromatographic membrane to develop an ultra-fast, highly-sensitive lateral-flow assay for cTnI.

Scientists have designed a liquid that behaves as both a solid and a fluid owing to the presence of tiny gas-filled capsules. An unusual relationship between pressure and volume enables this material to grasp fragile objects.
