Output control of dissipative nonlinear multimode amplifiers using spacetime symmetry mapping
Nature Physics, Published online: 01 April 2025; doi:10.1038/s41567-025-02853-5
In many optical systems with time-reversal symmetry, it is possible to control the output waves by shaping the input fields. Now a scheme is presented that works for multimode fibres that lack time-reversal symmetry due to thermal effects.

Thermopower probes of emergent local moments in magic-angle twisted bilayer graphene
Nature Physics, Published online: 31 March 2025; doi:10.1038/s41567-025-02849-1
It is well known that flat bands exist in magic-angle twisted bilayer graphene. Now thermopower measurements show that the strong correlations between electrons in these bands result in the formation of local moments.

Yielding behaviour of active particles in bulk and in confinement
Nature Physics, Published online: 31 March 2025; doi:10.1038/s41567-025-02843-7
Assemblies of active particles display a range of dynamical phenomena. Simulations now show that the transition of an assembly of active particles from a jammed to a fluidized state is similar to the process of mechanical yielding seen in amorphous solids.

Cooperative hydrodynamics accompany multicellular-like colonial organization in the unicellular ciliate <i>Stentor</i>
Nature Physics, Published online: 31 March 2025; doi:10.1038/s41567-025-02787-y
How unicellular organisms evolved into multicellular ones is an open question. Now, using unicellular Stentor coeruleus as a model system, the transition between isolated individuals and a coordinated colony is shown to benefit all colony members.

Good feeders make good neighbours
Nature Physics, Published online: 31 March 2025; doi:10.1038/s41567-025-02793-0
The transition from single cells to multicellularity is a key but not well-understood step in animal evolution. A study shows that loosely-organized colonies of attached single-celled organisms can improve feeding through hydrodynamic cooperation.

Direct observation of colloidal quasicrystallization
Nature Physics, Published online: 31 March 2025; doi:10.1038/s41567-025-02859-z
Quasicrystals, which lack translational symmetry but display rotational order, are difficult to make. Now an assembly method for the fabrication of colloidal quasicrystals that offers a high degree of controllability and reversibility is reported.
