  • Nonreciprocal transmission of waves is crucial for transport and redistribution of energy, yet the architecture to break time-reversal symmetry is hard to realise. Here, the authors proposed elastic-wave circulator that could achieve this without breaking reciprocity, enabling mode transition and wave trapping concurrently.

  • The interplay between competing orders in high-temperature superconductors can be tuned by the application of magnetic fields. Here, Chang et al. report high field induced three-dimensional charge density wave in underdoped YBa2Cu3O6.67, which suggests Fermi surface reconstruction due to competing orders.

  • Active metamaterials can host non-Hermitian interactions that defy the conservation laws of linear elasticity, leading to unusual phenomena such as one-way energy transmission and odd-elastic moduli. Here, robust unidirectional Rayleigh surface waves are found in active media comprising both gyroscopic and odd-elastic effects.

  • Denoising low-counting statistics data in the presence of multiple, unknown noise profiles is a challenging task in scientific applications where high accuracy is required. Oppliger and colleagues train a deep convolutional neural network on pairs of experimental low- and high-noise X-ray diffraction data and demonstrate better performance on experimental noise filtering compared with the case of training on artificial data pairs.

  • Chiral communication can propagate in secondary structures within the effective intermolecular force (IMF) range but it is not known whether long-range chiral communication exists between tertiary peptide structures. Here, the authors use single-molecule force spectroscopy to investigate chiral interaction between DNA duplexes/triplexes and peptide coiled-coils and demonstrate chiral communication beyond the IMF distance.

  • Enzyme reactions at interfaces are common in both Nature and industrial applications but no general kinetic framework exists for interfacial enzymes. Here, the authors kinetically characterize 83 cellulases and identify a scaling relationship between ligand binding strength and maximal turnover, a so-called linear free energy relationship, which may help rationalize cellulolytic mechanisms and guide the selection of technical enzymes.
