High-entropy oxides (HEOs) have emerged as a promising class of memristive materials, characterized by entropy-stabilized crystal structures, multivalent cation coordination, and tunable defect landscapes. These intrinsic features enable forming-free resistive switching, multilevel conductance modulation, and synaptic plasticity, making HEOs attractive for neuromorphic computing. This review outlines recent progress in HEO-based memristors across materials engineering, switching mechanisms, and synaptic emulation. Particular attention is given to vacancy migration, phase transitions, and valence-state dynamics—mechanisms that underlie the switching behaviors observed in both amorphous and crystalline systems. Their relevance to neuromorphic functions such as short-term plasticity and spike-timing-dependent learning is also examined. While encouraging results have been achieved at the device level, challenges remain in conductance precision, variability control, and scalable integration. Addressing these demands a concerted effort across materials design, interface optimization, and task-aware modeling. With such integration, HEO memristors offer a compelling pathway toward energy-efficient and adaptable brain-inspired electronics.

Most japonica rice varieties possess similar alleles for grain size, producing short and wide grains.

The gs9^ko allele has a widely applicable effect on grain appearance improvement. The increased leaf angle of the gs9^ko allele does not affect its improvement effect.

A rapidly growing field is piezoresistive sensor for accurate respiration rate monitoring to suppress the worldwide respiratory illness. However, a large neglected issue is the sensing durability and accuracy without interference since the expiratory pressure always coupled with external humidity and temperature variations, as well as mechanical motion artifacts. Herein, a robust and biodegradable piezoresistive sensor is reported that consists of heterogeneous MXene/cellulose-gelation sensing layer and Ag-based interdigital electrode, featuring customizable cylindrical interface arrangement and compact hierarchical laminated architecture for collectively regulating the piezoresistive response and mechanical robustness, thereby realizing the long-term breath-induced pressure detection. Notably, molecular dynamics simulations reveal the frequent angle inversion and reorientation of MXene/cellulose in vacuum filtration, driven by shear forces and interfacial interactions, which facilitate the establishment of hydrogen bonds and optimize the architecture design in sensing layer. The resultant sensor delivers unprecedented collection features of superior stability for off-axis deformation (0–120°, ~ 2.8 × 10^–3 A) and sensing accuracy without crosstalk (humidity 50%–100% and temperature 30–80 °C). Besides, the sensor-embedded mask together with machine learning models is achieved to train and classify the respiration status for volunteers with different ages (average prediction accuracy ~ 90%). It is envisioned that the customizable architecture design and sensor paradigm will shed light on the advanced stability of sustainable electronics and pave the way for the commercial application in respiratory monitory.

Targeting the issue of immunosuppression in the tumor microenvironment (TME) during hepatocellular carcinoma (HCC) immunotherapy, this study was the first to confirm that melarsoprol (MEL), an arsenic-containing drug, activates the cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS)-stimulator of interferon genes (STING) pathway in tumor cells and induces an antitumor immune response . However, high-dose MEL excessively activates the pro-tumorigenic cytokine tumor necrosis factor-α (TNF-α), which impairs the immunotherapeutic efficacy. To address this, a poly(D,L-lactic-co-glycolic acid) (PLGA)-based nanoparticle (NP) was prepared in this study for the co-delivery of MEL and lenalidomide (LEN), a TNF-α inhibitor. Through erythrocyte membrane camouflage and aminoethyl anisamide (AEAA)-targeted modification, the nanoparticle was precisely enriched in HCC tissues. It significantly reversed the immunosuppressive TME and achieved antitumor effects in two mouse models of HCC . This study provides a novel strategy for the chemoimmunotherapy of HCC.
