Skyrmions are a type of topological spin texture that great potential across a wide variety of technological applications. Here, Yu et al. study the thermally driven motion of Skyrmions and find a minimum temperature gradient for the motion of skyrmions two orders of magnitude smaller than for ___domain walls.

A Lorentz transmission electron microscopy study of a thin iron germanium film reveals the aggregation dynamics of skyrmions when pushed out of equilibrium.

Melting and squeezing pure metals between two sapphires covered in molybdenum disulfide produces diverse two-dimensional metals at the ångström thickness limit.

Quantum geometry effects in condensed matter physics are a topic of growing interest. Here, the authors show that the quantum geometry associated with excitons can generate detectable shift currents in a wide-gap semiconductor.

Antiskyrmions, like skyrmions, are a form of topological spin texture, with a topological charge of opposite sign to the equivalent skyrmion with the same polarity. While antiskyrmions have been less explored, they offer some potential advantages for applications, and here, Guang et al demonstrate antiskyrmion motion within stripe domains.

The magnetic fields of an individual lattice plane inside materials with a non-uniform structure were observed under magnetic-field-free conditions by electron holography.

Topological spin textures, such as skyrmions and antiskyrmions are of interest for use in information storage, owing to their inherent robustness. Critical to this use is the ability to manipulate these spin textures. Here, Yasin et al. demonstrate heat current driven transformation of a topological spin texture in a ferromagnet at room temperature.

The DAWN study is a phase 3 clinical trial that demonstrates effective glycemic control of dorzagliatin as an add-on therapy to metfomin in patients with type 2 diabetes.

Electron holography is used to visualize the three-dimensional structure of a skyrmion lattice and the magnetic flux inside and outside a skyrmion.

Fate-mapping and clonal analysis show that bronchioalveolar stem cells (BASCs) become activated and respond distinctly to different lung injuries and differentiate into multiple cell types. Single-cell RNA-seq analysis identifies new BASC markers.

2D MoS₂ is being intensively investigated as a promising candidate to extend the downscaling of electronic devices. Here, the authors report a buffer-layer-control method for the growth of wafer-scale single-crystalline MoS₂ monolayers on industry-compatible sapphire substrates with competitive optical and electronic properties.

Skyrmions, topological spin textures, have attracted interest for use in spin-based information processing. Here, Peng et al analyse the current driven motion of a single skyrmion at room temperature in a chiral-lattice magnet, tracking the motion using Lorentz transmission electron microscopy.

The real-space magnetic configurations of a zero-dimensional skyrmionic vortex structure is uncovered using electron holography and micromagnetic simulations.

The anomalous Hall effect (AHE) due to electron scattering process is typically limited to a small magnitude. Here, the authors report giant AHE of electron scattering origin in a chiral magnet MnGe thin film, possibly due to skew-scattering via thermally excited spin-clusters with scalar spin chirality.

Antiskyrmions had only been observed in a few Heusler compounds with D_2d symmetry. Here a new material, Fe_1.9Ni_0.9Pd_0.2P, in a different symmetry class (S₄ symmetry) is reported to host antiskyrmions, as well as sawtooth surface textures and skyrmions.

Experimental realizations of magnetic skyrmions, particle-like spin swirls with topological protection, so far have required inversion symmetry breaking or a geometrically frustrated lattice. In centrosymmetric GdRu₂Si₂, in which a geometrically frustrated lattice is absent, a skyrmion lattice phase emerges, which is probably stabilized by four-spin interactions mediated by itinerant electrons in the presence of easy-axis anisotropy.

Fetal trabecular muscles in the heart undergo a poorly described morphogenetic process that results into a solidified compact myocardium after birth. Tian et al. show that cardiomyocytes in the fetal compact layer also contribute to this process, forming a hybrid myocardial zone that is composed of cells derived from both trabecular and compact layers.

Understanding and controlling the skyrmion lattice (SkL) phase facilitates its versatile applications. Here the direct observation of a SkL phase with large topological Hall effect in centrosymmetric Gd₃Ru₄Al₁₂ is reported, which is stabilized by thermal fluctuations and magnetic field without Dzyaloshinskii-Moriya interactions.

Hepatocytes are highly specialized cells and their fate is determined by their position in the liver as either periportal or perivenous hepatocytes. Here, Pu et al. show through genetic lineage tracing for Mfsd2 that periportal hepatocytes proliferate and reprogram into pericentral hepatocytes during liver regeneration and injury.

Apelin expression is robust in embryonic but not in adult endothelial cells (ECs), where it can be reactivated by hypoxia. Liu et al. show that apelin-driven expression of Cre recombinase in mice can be used for labelling of, or gene ablation in, sprouting but not quiescent ECs in pathologies characterized by hypoxia.

Skyrmions are stable topological textures with particle-like properties — a mathematical concept that was originally used to describe nuclear particles but has since turned up at all scales. Last year, the presence of skyrmions in the magnetic compounds MnSi and Fe_1−xCo_xSi was confirmed with neutron-scattering experiments. Here, real-space images are presented of a two-dimensional skyrmion lattice in a thin film of the latter compound. The observed nanometre-scale spin topology might reveal new magneto-transport effects.

Skyrmions are vortex-like arrangements of spin magnetic moments, which so far have been observed in only a few compounds, and only at low temperatures. The discovery that skyrmions can be stabilized by thin magnetic films close to room temperature promises their use in spintronic devices.

Skyrmions and antiskyrmions are nanometric spin whirls with opposite topological charges. In the Heusler magnet Mn_1.4Pt_0.9Pd_0.1Sn, modulations of the orientation and strength of an in-plane magnetic field induces the transformation from antiskyrmions to non-topological bubbles and skyrmions.

Genetic cell-lineage tracing studies in mice are crucial for delineating the contribution of stem and progenitor cells to different cell types, both in disease states and after regenerative therapy. He et al. have developed new genetic lineage-tracing systems that provide more definitive results than the commonly used Cre-based system and show that this new technology can resolve current controversies in the field, as demonstrated by lineage-tracing studies in the heart and liver.

3D skyrmion strings are topological spin textures promising for spintronics applications, but their manipulation and dynamics are challenging to understand.

Ac current-driven spin motions in helimagnetic metals can generate emergent electric fields acting on conduction electrons, leading to emergent electromagnetic induction (EEMI).
