Spin waves are excited in a thin film of bismuth-doped yttrium iron garnet using radio-frequency pulses and interact with magnetic domain walls. Pulses as short as 1 ns translate a domain wall over 15 µm distances, offering control over domain-wall dynamics.

Autonomous microfluidics with plasmonic hot electron injection accelerates colorimetric DNA/RNA amplification detection and rapid diagnosis of pathogens in patient samples on par with polymerase chain reaction.

Quantum emitters with strong and tunable coupling to breathing-mode phonons are observed in bilayer WSe₂. The emission of each single photon heralds the creation of a phonon Fock state in the atomic-scale excitonic–optomechanical system.

A versatile hydrothermal approach in an operando acidic environment created ferromagnetic single-atom spin catalysts (SASCs). Ni-based SASC exhibits a giant magnetic field enhancement of OER activity, boosting both water and saline water electrolysis.

A large array of ferroelectric field-effect transistors with record memory windows, ON/OFF ratios and ON-current density is presented at ~80 nm channel length.

A quest to resolve ultra-high vacuum synthesis of high-quality, single-crystalline metal oxide thin films containing hard-to-oxidize metals reveals a hidden role of epitaxial strain on the metal oxidation chemistry and resulting thin-film growth.

Creation of cell spheroids by using triggered d-peptide self-assembly is reported. Peptides are dephosphorylated by transcytosis in cells and intercellularly assembled to facilitate fibronectin fibrillogenesis and subsequent spheroid formation.

Cancer resistance to apoptosis can hinder T-cell-based therapies. Here, the authors develop a temperature-sensitive system for the controlled delivery of a Cas9 gene-editing sequence targeting resistance mechanisms HSP70 and BAG3, which with a mild thermal effect increases T-cell delivery and therapeutic outcomes.

Collisions between two individual electrons in a quantum nanoelectronic circuit revealed a mutual interaction fully mediated by Coulomb repulsion—an essential building block for two-qubit logic implementations with flying electrons.

Domain wall formation and propagation using a small electric voltage are demonstrated in ferro-rotational 1T-TaS₂, although the ferroic order does not couple with electromagnetic fields, providing an opportunity for the manipulation and application of ferro-rotational order.

Coincidence correlations between ballistic on-demand electrons passing through a mesoscopic beam splitter are measured and modelled to reveal signatures of unscreened Coulomb interactions, establishing a platform for quantum nonlinearity.

Coulomb forces between ballistic electrons are detected and analysed using a mesoscopic electron collider in an unscreened regime. Controlling Coulomb interactions on picosecond time scales is key for quantum logic devices with flying electrons.

The implementation of topological antiferromagnetic vortices in information storage devices requires an efficient method of nucleation and a way to control their movement. Here the authors find CuMnAs to be a suitable electrically conducting antiferromagnet host material for topological spin textures.

Based on symmetry-breaking perturbations, leaky-wave metasurfaces with pointwise control of the amplitude, phase and polarization of surface emission offer a universal generalization of grating couplers for integrated photonics.

Non-equilibrium mechanical activity in active matter is quantified across spatiotemporal scales through time-reversal-asymmetry measurements of conformational fluctuations of carbon nanotube probes.

Microcompartments with a temperature-responsive membrane are used to stably localize DNA-encoded files, which enables parallel, repeated polymerase-chain-reaction-based random access and DNA file sorting using fluorescent barcodes.

Atomically thin heterostructures function as optomemristors, which are used for biomimetic neural algorithms for performing winner-take-all tasks, such as competitive and cooperative learning.

An artificial ligament replacement is made from aligned carbon nanotubes formed into hierarchical helical fibres with nanometre and micrometre channels which are demonstrated for the replacement of anterior cruciate ligaments in both rabbit and ovine models, showing strong integration and functional recovery.

Optimizing the retention of drug delivery nanocarriers for improved cancer therapy has the potential to improve clinical outcomes. Here the authors screen 20 renal-clearable zwitterionic cyclodextrin-based nanocarriers for optimized biodistribution and tumour retention, demonstrating application in colorectal cancer models.

Monolayer MoS₂ is grown at the back end of the line of 200 mm silicon CMOS wafers at a temperature of <300 °C, and hybrid silicon CMOS/MoS₂ circuits are demonstrated through heterogeneous integration.
