5G/6G expansion intensifies electromagnetic interference, demanding high‑performance absorbers (EWAs). Conventional equilibrium syntheses suffer from slow diffusion and long heating, driving materials toward stable configurations that erase defect‑rich, metastable features beneficial for microwave loss. Flash Joule heating (FJH) offers a paradigm shift: millisecond electrical pulses generate >3000 K and ultrafast quenching, trapping materials in non‑equilibrium states. This perspective establishes FJH as a programmable platform for designing EWAs with tailored defects, metastable interfaces, and discontinuous networks.
Organic fluorophores operating in the second near-infrared window can provide deep-tissue images with high contrast, but their performance often depends on nanocarriers that can prevent hydrophobic dyes from leaking in complex biological environments. Researchers at Tong and Xiang’s group have developed multivalent tetraphenylethylene-modified DNA nanoaggregates that remain assembled under denaturing conditions, stably retain NIR-II fluorophores, and enable high-contrast vascular imaging in living mice.
In the review, researchers summarize the latest advances in triboelectric nanogenerator (TENG) fibers for self-powered sensing in virtual reality (VR) and augmented reality (AR). These fiber- and fabric-based sensors are flexible, breathable, and comfortable, converting the wearer's movements and physiological signals directly into electrical signals that drive immersive human–computer interaction. The authors survey TENG fiber structures, scalable production and integration methods, strategies to boost electrical output, and key VR/AR applications—from wearable virtual buttons to gesture recognition and virtual-character control—while outlining the remaining challenges on the path to practical, commercializable products.
Melon flesh thickness is the edible portion of the fruit and directly determines its commercial value and yield, yet the genes controlling this trait have long remained a mystery.
Precision forestry has long lacked a reliable way to predict how light moves through tree canopies over time—a gap that limits everything from pruning decisions to yield optimization.
A review traces One Health from historical disease-control lessons to today’s interconnected threats and proposes an “interface-resilience” model. The model links spillover pressure, microbial community stability and governance connectivity to systemic health risk, offering a framework for earlier warning, cross-sector surveillance and preventive, data-driven health governance.
The Moon no longer has a global magnetic field, but lunar rocks and soils still contain records of ancient magnetism. Therefore, studying the magnetic minerals in these samples can help scientists understand how the Moon’s magnetic field evolved over time. Recently, researchers examining impact-glass particles containing metallic iron from Chang’e-6 lunar soil samples discovered face-centered cubic γ-Fe—the first time this iron phase has been identified in natural lunar samples.
