Circadian disruption can promote tumour formation. Now it is shown that the loss of circadian synchronization can drive this effect by disrupting the coupling between the circadian rhythm and the cell cycle within individual cells.

- Circadian coupling orchestrates cell growth
- Direct observation of colloidal quasicrystallizationNature 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.
- Thermopower probes of emergent local moments in magic-angle twisted bilayer grapheneNature 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.
- 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.
- Yielding behaviour of active particles in bulk and in confinementNature 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.
- Good feeders make good neighboursNature 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.
- Acousto-dewetting enables droplet microfluidics on superhydrophilic surfacesNature Physics, Published online: 28 March 2025; doi:10.1038/s41567-025-02844-6 In droplet microfluidic setups, droplets are driven around on a surface, which is normally hydrophobic. Now, droplet microfluidics with superhydrophilic substrates is shown to also be feasible by exploiting acoustic effects.
- Enzymes as viscoelastic catalytic machinesNature Physics, Published online: 28 March 2025; doi:10.1038/s41567-025-02825-9 Enzymes are viscoelastic, deformable machines. Mutating high-strain regions in these machines affect their catalytic function.
