Dense suspensions of soft particles possess relatively complex rheological properties, such as the existence of a threshold stress to flow. A new statistical physics approach allows to obtain a tensor constitutive model from the dynamics of the soft particles of the suspension, and thus to link the rheology to the anisotropy of the microstructure.

By probing complex scattering systems with shaped light fields, it is now possible to detect hidden objects with exceptionally low photon fluxes.

Biochemical signaling by red blood cells (RBCs) is essential for proper regulation of blood flow, and understanding it allows the design of
therapies adapted to cardiovascular pathologies. The release of ATP (Adenosine Triphosphate) by RBCs is a major mechanism that has been modeled in this work, revealing the existence of an optimal hematocrit for better ATP release.

The authors of these studies have modeled the buckling dynamics of elastic shells, opening the way to the controlled use of these objects to generate small-scale flows, for applications such as mixing, or propulsion and control of immersed microbots.

Just like the effect of surfactants acting on the surfaces between two media such as water and air, there can be a lineactant effect on the lines separating three media. Physicists show here for the first time such an effect for carbon dioxide (CO2) in contact with a drop of water confined in a nanopore.
