- Membraneless protocell confined by a heat flow
- Quantum neural networks can be normalNature Physics, Published online: 24 June 2025; doi:10.1038/s41567-025-02941-6 As many classical neural networks get larger, they can be described as Gaussian processes, the generalization of the normal distribution to infinite dimensions. A similar connection has now been proven for quantum neural networks.
- Intercellular flow dominates the poroelasticity of multicellular tissuesNature Physics, Published online: 20 June 2025; doi:10.1038/s41567-025-02947-0 Tissues are usually modelled as viscoelastic materials. Now it is shown that intercellular fluid flow, rather than viscoelastic behaviour, dominates the immediate mechanical response of tissues.
- Neutron scattering and thermodynamic evidence for emergent photons and fractionalization in a pyrochlore spin iceNature Physics, Published online: 19 June 2025; doi:10.1038/s41567-025-02922-9 Quantum spin-ice phases are predicted to have emergent gauge fields and fractionalization. Neutron scattering and thermodynamic measurements of the quantum spin-ice candidate Ce2Zr2O7 show features consistent with these predictions.
- Floquet states in graphene revealed at lastNature Physics, Published online: 19 June 2025; doi:10.1038/s41567-025-02939-0 Time-resolved photoemission shows evidence of Floquet states in graphene, resolving a long-standing debate and unlocking engineering of quantum phases with light in semi-metals.
- Feedback between F-actin organization and active stress governs criticality and energy localization in the cell cytoskeletonNature Physics, Published online: 18 June 2025; doi:10.1038/s41567-025-02919-4 Self-organized criticality can occur in cellular systems, but its origins remain unclear. Now it is shown that cytoskeletal criticality is influenced by the F-actin architecture and myosin active stress.
- From actin to actionNature Physics, Published online: 18 June 2025; doi:10.1038/s41567-025-02937-2 Cells undergo structural rearrangements to enable migration and changes in morphology. A study using reconstituted actomyosin revealed that these earthquake-like events are driven by F-actin organization and active stress generation.
- Driven quantum fluids sound like supersolidsNature Physics, Published online: 18 June 2025; doi:10.1038/s41567-025-02934-5 Quantum gases develop modulated patterns when subjected to a continuous drive. An experiment has now demonstrated that, in a driven quantum system, the sound propagates with two distinct speeds, reflecting both superfluid and crystalline properties — a feature of supersolidity.
