A research team has identified two complementary mechanisms through which huperzine A improves cognition in mice with vascular dementia, linking protection of nerve cells with regulation of a brain circuit involved in cognitive function.

A research team led by Dr. Sun-Mi Hwang from the Clean Air Research Laboratory at the Korea Institute of Energy Research (KIER, President Hakgeun Jeong) has developed novel catalysts as an all-in-one solution to address exhaust emissions from eco-friendly ammonia-fueled ships. This technology can simultaneously and cost-effectively remove various greenhouse gases from ammonia combustion, and is therefore expected to significantly contribute to achieving carbon neutrality in the maritime industry.

Aerogel fibers have been considered as a promising solution for thermal protection textiles due to their high porosity and low thermal conductivity. However, the scalable production of sustainable and mechanical strong aerogel fibers remains a critical challenge. Here, inspired by the porous core–shell structure of polar bear hair, we report a continuous strategy to fabricate all-biomass aerogel fibers featuring an encapsulated core–shell architecture using silk fibroin as the core and cellulose as the shell. This tunable structure, with radially aligned sheet-like pores and adjustable shell thickness, is achieved through hydrogen bond-driven cellulose contraction and alcohol-induced curing of sheet-like silk fibroin. Such a porous architecture effectively suppresses convective heat transfer and promotes a multi-reflective effect for infrared radiation. The resulting fibers exhibit good mechanical robustness with a tensile load of a single aerogel fiber is up to 200 g without reinforcement. Meanwhile, the aerogel fiber maintains high porosity (79.78%), low thermal conductivity (52.4 ± 4.2 mW m⁻¹ K⁻¹), and low density (0.193 ± 0.01 g cm⁻³). Furthermore, an aerogel glove fabricated from these fibers demonstrates good thermal insulation. These results provide new insights for the design of biomimetic aerogel fibers with core–shell architecture, offering a scalable and eco-friendly pathway toward advanced wearable thermal management.

The aqueous zinc metal batteries (AZMBs) are famous for high-safety and high-energy-density, but limited by severe challenges around the Helmholtz plane layer such as the strong ion–dipole interactions between Zn²⁺ and H₂O, resulting in slow desolvation processes and limited transport kinetics as well as corresponding higher barriers. To reconstruct the ion–dipole surroundings, the interface chemistry of employing a high permanent dipole moment of L-Carnosine (L-CN) has been proposed, weakening the interactions between Zn²⁺ and H₂O to realize a crowded Zn²⁺-conductive structure, accelerating the desolvation kinetics. As revealed, the strong affinity between L-CN and Zn²⁺ enables the L-CN molecules to repulse H₂O, reconfiguring the inner Helmholtz plane layer, thereby inhibiting the active water molecular to form hydrogen evolution reactions. Consequently, the Zn//Zn symmetric cells with Helmholtz plane modulation achieve a long lifespan up to 7000 h, a high Coulombic efficiency of 99.72%, and a high stabilization at high depth of discharge (85.4%). The assembled Zn//V₂O_5−x full cell with optimal electrolyte delivers the capacity of 289 mAh g⁻¹ after 500 cycles at 1 A g⁻¹ under an N/P ratio of 3.98. Impressively, the large-scale pouch cell with optimal electrolyte stabilizes for 200 cycles, offering the bright future of reconstructing Helmholtz plane for achieving high-performance AZMBs.

Using a two-sample Mendelian randomization approach, this study (1349 cases, 203,231 controls from the FinnGen study) examined causal associations between 16 lifestyle behaviors and potential risk factors and blepharoptosis. Genetically predicted leisure screen time was associated with higher odds of blepharoptosis, with indicative evidence for BMI and current smoking as risk factors and physical activity and smoking cessation as protective factors.

This structured narrative review synthesizes evidence from randomized controlled trials, prospective studies, retrospective multicentric cohorts, and real-world investigations evaluating low-dose atropine (≤0.05%) for myopia control in Indian children. Indian studies consistently show that 0.01% atropine reduces myopia progression by approximately 50%–65% with minimal adverse effects, while 0.05% atropine offers greater efficacy with slightly more mild ocular side effects, consistent with international trials such as ATOM and LAMP.

This systematic review (12 studies, 2302 patients), published in Eye & ENT Research, synthesizes available evidence on the association between human metapneumovirus (HMPV) infection and otorhinolaryngological manifestations. Acute otitis media was the most frequently reported ENT manifestation, and most patients were children (88.3%). Given the marked heterogeneity across studies, the findings point to a possible association, but causality cannot be established from the current evidence.

Researchers have introduced a laser-triggered material platform that allows soft electronic devices and soft robots to be selectively erased, reshaped, or reprogrammed from a distance. By using light as a remote “transform button,” the technology enables rapid, localized decomposition of soft materials—opening new possibilities for secure device disposal, adaptive robotics, and operation in hard-to-access, resource-limited environments.
