- Crystal-symmetry-paired spin–valley locking in a layered room-temperature metallic altermagnet candidate
- Circadian coupling orchestrates cell growthNature Physics, Published online: 31 March 2025; doi:10.1038/s41567-025-02838-4 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.
- 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.
- Twist angle serves as a tuning knob for superconductivityNature Physics, Published online: 28 March 2025; doi:10.1038/s41567-025-02829-5 Ultra-low-temperature scanning tunnelling spectroscopy measurements indicate that twisting the layers in heterostructures making up a single layer of superconducting NbSe2 on graphene leads to momentum-dependent changes in the superconducting gap. This ability could enable the development of artificial superconductors with nontrivial magnetic and topological properties.
- A qudit quantum computer for simulation of two-dimensional quantum electrodynamicsNature Physics, Published online: 28 March 2025; doi:10.1038/s41567-025-02821-z Quantum electrodynamics (QED) is a cornerstone of the standard model of particle physics. A decade-long effort to simulate QED on a two-dimensional lattice has now succeeded — through the use of a trapped-ion quantum computer based on multidimensional ‘qudits’, which are uniquely suited to the challenge.
- Optical control of an excitable enzyme circuit for engineering dynamic cell shapesNature Physics, Published online: 28 March 2025; doi:10.1038/s41567-025-02810-2 Light-switchable enzymes hold great promise for mediating molecular activations in living cells, yet their full potential in realizing versatile controls in nonlinear networks remains unexplored. Now, optical control is demonstrated over a key enzyme involved in animal cell division, and a diverse array of dynamic cell shapes is achieved by biochemically hacking an endogenous signalling circuit.
- The mechanics of protein sweet spotsNature Physics, Published online: 28 March 2025; doi:10.1038/s41567-025-02826-8 Proteins rely on dynamic flexibility to function as life’s molecular machines. Now, artificial intelligence predictions and mechanics experiments reveal how mutations at specific protein sites modulate enzyme catalysis, advancing protein design.
