Amorphous chalcogenide alloys are promising for Ovonic threshold switching selectors, yet elemental chalcogen based-material design is hindered by poor glass-forming ability of chalcogen species. Hur et al. show defect-mediated switching and self-regulated oscillations in an amorphous Te phase stabilized via on-device quenching.

Experiments on a noisy 127-qubit superconducting quantum processor report the accurate measurement of expectation values beyond the reach of current brute-force classical computation, demonstrating evidence for the utility of quantum computing before fault tolerance.

Studying many-body quantum chaos on current quantum hardware is hindered by noise and limited scalability. Now it is shown that a superconducting processor, combined with error mitigation, can accurately simulate dual-unitary circuit dynamics.

Robust conductive hydrogels made purely from a conducting polymer can be fabricated using a laser-induced phase separation method that also improves adhesion to a polymer substrate and allows high-resolution selective patterning.

Interactions between qubits and defect-related two-level systems in superconducting qubit devices are a major source of noise fluctuations that hinder error-mitigation performance. Here, the authors experimentally show that modulating this interaction can reduce noise fluctuation and improve error mitigation performance.

The lack of understanding of mixed transport in ion-permeable conjugated polymer films hinders the advance of organic electrochemical transistors for bioelectronics. Here, the authors elucidate the structure-property-performance relationships for conventional and crystallized PEDOT:PSS films.

It remains unclear whether any set of the 68 gustatory receptors expressed in Drosophilacomprise a cation channel that responds to an aversive chemical. Here the authors identify three gustatory receptors that are both necessary and sufficient to form a channel that confers sensitivity to a noxious tastant.

A technique called error mitigation can significantly improve the performance of large-scale quantum computations on near-term devices without the significant resource overheard of fault-tolerant quantum error correction.

Quantum error correction will be the key to allow large-scale quantum computing operations in the future. Here, the authors use a superconducting qubit system to demonstrate quantum error correction of a distance-three logical qubit in the heavy-hexagon subsystem code.

Organisms have evolved diverse colouration strategies, including dynamic colour change, which enables their rapid adaptation to environmental stimuli. This Review discusses the recreation of bioinspired colouration and dynamic colour change mechanisms for applications in optics, sensors and biomedicine.

In textile electronics, micro to millimeter-scaled misalignment is commonly occurred during the high-throughput and bulk-scaled textile manufacturing process, thus the exact performance control of the fiber-based active devices is very difficult in low-cost wearable electronics. In this research, we developed novel single-strand organic electrochemical transistors and proposed dimension-independent characterization method (i.e., the current variation ratio in variation of logarithmic concentration of electrolyte) for ion concentration sensing. Furthermore, we demonstrated the pseudo two-terminal transistor operation by incorporating electrochemical gate electrode onto the surface of the source electrode, leading to single-strand fiber device platform.

The high performance polymer-based conductive cellular interface was developed by a solvent-assisted crystallization of PEDOT:PSS. The crystallized PEDOT:PSS(c-PEDOT:PSS) exhibited mechanical and electrical robustness over 21days as well as excellent electrical conductivity and electrochemical activities. Thanks to such advantageous properties for the cellular interfaces, the beating rates of cardiomyocytes cultured on c-PEDOT:PSS were successfully modulated through pulsed direct stimulation under 1 V. In addition, c-PEDOT:PSS incorporated Multielectrode arrays (MEAs) recorded real-time action potentials originated from cardiomyocytes with high signal fidelity. we expect c-PEDOT:PSS with high-performance and high-stability to be a promising candidate for long-term bioelectronic interface development.

Kim et al. use RNAseq of two watermelons to select candidate genes coding for enzymes that catalyze modifications of cucurbitacins. They characterise four of the 16 candidate enzymes (3 different acetyltransferases and one UDP-glucosyltransferase) by HPLC, LC-MS, NMR, and in vitro enzymatic assay. They further show with in vivo assay in Drosophila, that acetylation of cucurbitacin increases neuronal activity in insects.
