A research team has developed a chitosan-modified, phytic acid-doped polyaniline (CS/PA-PANI) electrode that rapidly and selectively captures uranium from aqueous environments through capacitive deionization. 

A network meta-analysis of 24 trials involving 744 participants has identified vertically resisted plyometric training as the most effective method for enhancing change-of-direction speed. The Bayesian analysis, led by Jishou University and the University of Freiburg, ranked this approach above nine other modalities, with vertically resisted sprint training second. Notably, the turning angle did not affect outcomes, suggesting that resisted training adaptations transfer across all directional changes.

This research shows a new way to control light at extremely high speeds using ultra-thin silicon metasurfaces. By carefully designing how light passes through them, the team achieved strong and fast control over a wider range of colours than previously possible. This breakthrough helps overcome a key limitation in current technology and could support faster internet, improved data processing, and future light-based computing systems.

A research team has developed a sustainable method for converting biomass and nitrogen-rich polyurethane (PU) waste into nitrogen-doped hierarchical porous carbon for aqueous zinc-ion hybrid capacitors (ZIHCs). 

Caloric restriction (CR) is an effective dietary intervention that delays aging and improves metabolic health. Previous studies have reported that lithocholic acid (LCA), a secondary bile acid, increases significantly in serum during CR. LCA has been shown to mimic the anti-aging effects of CR across multiple model organisms, including elevating muscle NAD⁺ levels, enhancing grip strength and exercise endurance in aged mice, and extending lifespan in nematodes and fruit flies.

The discovery of twisted graphene moiré superlattices has opened new avenues for exploring low-dimensional quantum states of matter. This review summarizes recent experimental and theoretical advances in twisted graphene systems, focusing on electron correlation, unconventional superconductivity, and topological states emerging from moiré flatbands, while highlighting their underlying mechanisms, characterization techniques, key open questions and future research directions.

Electrochemical chloride ion removal is essential for clean water and environmental protection, yet its practical application is hindered by the sluggish kinetics, especially using high-mass-loading electrodes. Conventional extrinsic modifications, such as conductive additives or structural design, exhibit constrained effectiveness. Here, we report an intrinsic enhancement strategy through heteroatom doping-induced dual defects engineering, demonstrated by the successful synthesis of fluorine-doped copper(I) phosphide with phosphorus vacancies (F-Cu₃P_V) via molten salt treatment. Based on density functional theory calculations and experimental results, F doping caused lattice distortion, generating P vacancies to form dual defects. These defects effectively modulated intrinsic electron redistribution, resulting in improved electrical conductivity, enhanced adsorption capability, and reduced chloride ion diffusion energy barriers. Therefore, electron transfer and ion diffusion kinetics were significantly accelerated, leading to superior electrochemical performance. Resultantly, the F-Cu₃P_V electrode performed exceptional electrochemical chloride ion removal performance with superior areal deionization capacity (3.16 ± 0.02 mg cm⁻²) and a remarkably rapid areal deionization rate (0.106 ± 0.001 mg cm⁻² min⁻¹), as well as outstanding cycling stability (95.65% retention after 70 cycles). This work elucidates electron redistribution via heteroatom doping-induced dual defects as a viable pathway to overcome the intrinsic kinetic bottleneck for high-performance electrochemical chloride ion removal.

Dynamically tunable terahertz (THz) wavefront modulators are essential components for next-generation communications. Researchers from China and Russia have designed and fabricated two stretchable metasurfaces based on single-walled carbon nanotube (SWCNT) film: a focal-length-tunable metasurface lens and another for controllable beam deflection. By applying mechanical stretching, these devices achieve superior dynamic terahertz wavefront manipulation and continuous tuning at 0.35 THz. This work lays a foundation for smart, wearable THz components in 6G communication and intelligent sensing.

A comparative machine learning study of older adults shows that objective mobility tests and contextual assessment variables outperform demographic information alone for distinguishing fallers from non-fallers. When combined with basic demographic information, mobility measures provide strong screening performance with lower assessment burden than more extensive questionnaire-based approaches.
