Layered materials governed by van der Waals (vdW) interactions offer opportunities for interlayer tuning of the materials' properties. Here, the authors demonstrate that in-plane tensile strain can effectively tune the vdW interactions of few-layered black phosphorus and weaken its interlayer coupling even though the sample shrinks in the vertical direction.

Anisotropic light-matter excitations in van der Waals materials are expected to have an impact on nanophotonics applications. Here, the authors report the observation of canalized in-plane mid-infrared plasmons in the semimetallic phase of WS₂ and demonstrate their electrical tunability via ion intercalation.

6R-TaS2 is a natural van der Waals heterostructure formed by 1H- and 1T-phase TaS₂ layers, which can individually exhibit Ising superconductivity, correlated states and charge density waves. Here, the authors show experimental evidence of emergent nematic Ising superconductivity with simultaneous hidden magnetism (extrinsic anomalous Hall effect and Kondo screening) in 6R-TaS₂ under 30 K.

How the carriers behave in a Weyl semimetal if they occupy the lowest Landau level remains elusive. Here, the authors report evidences of electrons occupying zeroth chiral Landau levels with distinct linear dispersion behaviors for two inequivalent Weyl nodes in a Weyl semimetal NbAs.

There is lack of therapies targeting the PAX3-FOXO1 fusion oncogene in fusion-positive rhabdomyosarcoma (FP-RMS). Here, the authors identify and characterise an inhibitor with highest inhibition of histone lysine demethylase 3B that suppresses PAX3-FOXO1 activity in FP-RMS.

Naturally occurring hyperbolic polaritons exist in a class of layered materials. Here, the authors show evidence, via optical spectroscopy, of hyperbolic exciton-polaritons in phosphorene, originating from its in-plane anisotropy and strong exciton resonances.

Here, the authors determine the exciton polarizabilities for 3- to 11-layer black phosphorus via frequency-resolved photocurrent measurements on dual-gate devices, and unveil the exciton response for higher-index sub-bands under the gate electrical field, as well as a carrier screening effect in thicker samples.

Unique electronmagnetic response of Weyl semimetals have only been reported in static field regime. Here, the authors report evidence of a dynamical chiral anomaly response realized by internal collective lattice deformation with an external static magnetic field in a Weyl semimetal NbAs.

Few-layered black phosphorus offers an infrared bandgap, complementing that of graphene and transition metal dichalcogenides. Here, the authors investigate the thickness- and strain-dependent electronic structure of black phosphorus using polarised infrared spectroscopy.

Rhabdomyosarcoma (RMS) is a pediatric malignancy of skeletal muscle lineage with an aggressive subtype caused by translocations involving PAX3- /PAX7-FOXO1 chimeric transcription factors. Here the authors show that the BRG1-containing BAF complex is overexpressed and acts largely independently of the PAX3-FOXO1 chimera on chromatin to result in a myogenic differentiation blockade in this malignancy.

Rapid growth of highly crystalline Covalent organic framework (COF) materials remains challenging. Here, the authors accelerate single-crystal polymerization using supercritical CO2 and realize the fabrication of two-dimensional COF single crystals within several minutes.

Here, arrays of 2H-TaSe2 nanoribbons are shown to exhibit a broadband plasmonic response that can be tuned from THz to telecom range. These localized plasmons can also couple to charge density wave excitations, offering insights on the physics of plasmonic excitations in 2D correlated materials.

For many two-dimensional semiconductors, such as MoS₂, the exciton absorption increases with thickness. Here, the authors show that, in black phosphorus, less material absorbs more light due to exciton resonances.

Hyperbolic plasmonic surfaces supporting highly directional propagating plasmon-polaritons have been realized in artificial metamaterials. Here, the authors demonstrate experimentally a hyperbolic plasmonic surface naturally occurring in thin films of WTe2, a type-II Weyl semimetal with layered structure.

Dongxin Lin, Philip Taylor, Li-Dong Wang and colleagues have now pooled three genome-wide association analyses of esophageal squamous cell carcinoma, finding two new risk loci at genome-wide significance and an HLA class II locus of significance in high-risk populations. They reanalyze the strength of evidence for previously published risk loci.

ZrTe₅ has attracted intensive research interests because of the potential topological property. Here based on the transports and optic experiments, we observe unusual Landau quantization, non-trivial Berry phase and highly anisotropic carrier mass, which reveals quasi-two-dimensional Dirac fermions in bulk ZrTe₅. The system is understood as locating at the critical point between a three-dimensional (3D) Dirac semimetal and a topological insulator. New physics or device application can be possibly realized in this quasi-2D ultra-relativistic system beyond graphene.
