  • 3D higher-order topological insulators (HOTIs) exhibit 1D hinge states depending on extrinsic sample details, while intrinsic features of HOTIs remain unknown. Here, K.S. Lin et al. introduce the framework of spin-resolved topology to show that helical HOTIs can realize a doubled axion insulator phase with nontrivial partial axion angles.

  • The existence of a topological bulk-boundary correspondence for Dirac semimetals has remained an open question. Here, Wieder et al. predict one-dimensional hinge states originating from bulk three-dimensional Dirac points in solid-state Dirac semimetals, revealing condensed matter Dirac fermions to be higher-order topological.

  • Although irrigation expansion during the 20th century masked or even reversed local warming trends over some intensely irrigated regions, the exposure to moist-heat extremes of local population has increased due to higher air humidity.

  • Strong electron–electron interactions create a charge-density wave that modifies the topological state of the Weyl semimetal (TaSe4)2I. This implies the possibility of experimentally simulating axion electrodynamics in a solid-state material.

  • The band topology of nonmagnetic crystals can be characterized by Topological Quantum Chemistry (TQC), whereas the band topology of magnetic crystals remains unexplored. Here, the authors extend TQC to the magnetic space groups to form a complete, real-space theory of band topology in magnetic and nonmagnetic crystalline solids.

  • Many topological crystalline phases have unknown physical responses. Here, the authors systematically extend the theory of defect and flux responses to predict zero-dimensional (0D) states in topological crystalline materials, including 2D PbTe monolayers and 3D SnTe.

  • The development of multimodality and targeted treatment strategies has improved the prognosis of patients with gastrointestinal cancers. Not all patients, however, benefit equally from these treatment approaches, and the ability to predict who will respond positively to a treatment type is of particular importance. This Review discusses the role of biomarkers and metabolic imaging approaches in the prediction of response to therapy early on in treatment.
