Active matter exhibits positional coherence in addition to the well-known orientational order. It is now shown that coherent structures in active nematics—made of dynamical attractors and repellers—form, move and deform, steered by topological defects.

Dynamic arrest in amorphous gels has so far been ascribed to glass transition. Now, experiments reveal a hierarchical structural ordering in dilute colloidal gels driven by the local potential energy, making this type of gel distinct from amorphous glasses.

Semiconductor qubits can benefit from existing industrial methods, but there are challenges in coupling qubits together. A hybrid superconductor–semiconductor qubit that couples to superconducting qubit devices may overcome these issues.

The direct observation of spin Berry curvature, an important aspect of non-trivial band topology, has not been achieved in quantum materials. Now it is observed in a bilayer Kagome metal.

A moiré potential may play a role in determining the magnetic properties of a two-dimensional homo or heterostructure. Now, non-collinear spin structures are observed in twisted double bilayer CrI₃, providing a platform to engineer unusual magnetic textures.

Through a mechanochemical feedback loop involving Min proteins of Escherichia coli, liposomes start to move, which may help to design motile artificial cells.

The eco-system of companies and start-ups developing quantum technologies is booming, but the disparity between private and public funding may become an issue in the absence of commercial uses.

Despite their differences, the six regional metrology organizations work together to provide and advance the global equivalence of national measurements standards, as Hyun Min Park explains.

As sharing of research data becomes more important, we are facilitating this by integrating the Figshare repository into our submission system.
