The proliferation of 5G communication technology and the miniaturization of electronic devices have made protection against human electromagnetic radiation an urgent global public health issue. Concurrently, intensifying great power arms races are driving electromagnetic warfare environments towards full-spectrum capabilities and intelligentization. Microwave (300 MHz–300 GHz) and terahertz wave (0.1–10 THz) technologies, as core frequency bands in electromagnetic spectrum engineering, have deeply penetrated critical fields such as communications, military, healthcare, and industrial inspection. Consequently, electromagnetic wave absorption and shielding have become imperative problems to solve. However, traditional absorbing materials face numerous challenges, such as singular loss mechanisms, a lack of adaptive cross-band regulation capability, and excessive thickness. These limitations severely restrict their application in complex electromagnetic compatibility scenarios.

Potatoes are one of the world's most important food crops, yet genetic improvements to increase tuber yield and quality have been constrained by the lack of a high-quality reference genome. 

Powdery mildew poses a major threat to black currant production, yet some cultivars naturally withstand infection far better than others. This study reveals that resistant black currants deploy a multilayered defense system involving physical structures, specialized metabolites, and the assembly of protective microbial communities on leaf surfaces. By integrating metabolomics and phyllosphere microbiome profiling, the research identifies key leaf metabolites—such as salicylic acid, trans-zeatin, and griseofulvin—that help recruit beneficial bacteria and fungi linked to disease suppression. These metabolites also directly reduce pathogen growth. Together, these processes explain how resistant cultivars mount a coordinated defense that limits pathogen invasion and maintains plant health.

Tomato fruit size, a trait that strongly influences market value and yield, is governed by intricate developmental processes. This study uncovers a previously unknown translational regulatory pathway mediated by the RNA-binding protein SlRBP1. Through fruit-specific gene manipulation, researchers show that SlRBP1 is essential for normal cell division and expansion within the tomato pericarp. The findings reveal that SlFBA7 and SlGPIMT are direct downstream gene targets whose translation is controlled by SlRBP1, and silencing either gene produces small fruits similar to SlRBP1-suppressed plants. This work highlights translational regulation as a key but underexplored mechanism for improving fruit size and overall productivity.

This study leverages advanced genomics and machine learning to refine the understanding of key fruit quality traits in peaches. Using whole-genome resequencing data from an F1 progeny of two distant peach cultivars, the researchers constructed an ultra-high-density genetic map, identifying key quantitative trait loci (QTLs) for traits such as fruit shape, color, and maturity. Notably, the study introduces machine learning models for more accurate phenotyping of fruit color, revealing two previously undetectable QTLs for peach flesh color variation. These innovations provide a new framework for precision breeding, enhancing peach quality and other complex traits through improved mapping and phenotyping strategies.

Composite solid electrolytes (CSEs) are promising for solid-state Li metal batteries but suffer from inferior room-temperature ionic conductivity due to sluggish ion transport and high cost due to expensive active ceramic fillers. Here, a host–guest inversion engineering strategy is proposed to develop superionic CSEs using cost-effective SiO₂ nanoparticles as passive ceramic hosts and poly(vinylidene fluoride-hexafluoropropylene) (PVH) microspheres as polymer guests, forming an unprecedented “polymer guest-in-ceramic host” (i.e., PVH-in-SiO₂) architecture differing from the traditional “ceramic guest-in-polymer host”. The PVH-in-SiO₂ exhibits excellent Li-salt dissociation, achieving high-concentration free Li⁺. Owing to the low diffusion energy barriers and high diffusion coefficient, the free Li⁺ is thermodynamically and kinetically favorable to migrate to and transport at the SiO₂/PVH interfaces. Consequently, the PVH-in-SiO₂ delivers an exceptional ionic conductivity of 1.32 × 10⁻³ S cm⁻¹ at 25 °C (vs. typically 10⁻⁵–10⁻⁴ S cm⁻¹ using high-cost active ceramics), achieved under an ultralow residual solvent content of 2.9 wt% (vs. 8–15 wt% in other CSEs). Additionally, PVH-in-SiO₂ is electrochemically stable with Li anode and various cathodes. Therefore, the PVH-in-SiO₂ demonstrates excellent high-rate cyclability in LiFePO₄|Li full cells (92.9% capacity-retention at 3C after 300 cycles under 25 °C) and outstanding stability with high-mass-loading LiFePO₄ (9.2 mg cm⁻¹) and high-voltage NCM622 (147.1 mAh g⁻¹). Furthermore, we verify the versatility of the host–guest inversion engineering strategy by fabricating Na-ion and K-ion-based PVH-in-SiO₂ CSEs with similarly excellent promotions in ionic conductivity. Our strategy offers a simple, low-cost approach to fabricating superionic CSEs for large-scale application of solid-state Li metal batteries and beyond.
