Sepsis can weaken the heart at the very moment the body most needs strong circulation, yet the biological chain driving this damage remains difficult to interrupt. 

This review systematically bridges non-resonant and resonant metasurfaces, highlighting their complementary roles in shaping next-generation photonic devices. It covers physical mechanisms, key structures, and transformative applications in imaging, color routing, and displays. The fusion of both paradigms promises multifunctional, chip‑integrated meta‑devices.

Atmospheric water vapor is vital to weather and climate research, yet estimating it from global navigation satellite system (GNSS) signals depends on an intermediate temperature value that global models may not represent accurately at regional scales. In Geodesy and Geodynamics, researchers introduce three models calibrated for Iran using radiosonde observations and radio occultation profiles from multiple satellite missions. Models using measured surface temperature performed best with radiosonde data, while a surface-temperature-independent model proved more reliable for satellite profiles and cut errors in GNSS-derived precipitable water vapor by about half at test stations in Tehran and Tabriz.

This review synthesizes collective insights from the 1st China–Australia–New Zealand Water Quality Modeling Symposium (CANWaS 2024) and outlines a roadmap for strengthening international collaboration in surface water quality modeling. Organized by Jiping Jiang from Harbin Institute of Technology and Danlu Guo from Australian National University, an international research team identifies shared priorities, mutual interests, and actionable pathways—including best-practice guidelines, open knowledge sharing, and joint technological innovation—to advance predictive capacity and policy impact for global freshwater management.

Researchers from the Kunming Institute of Botany, Chinese Academy of Sciences, have demonstrated that Rheum nobile, a flagship alpine plant in the Himalaya-Hengduan Mountains long treated as a single species, actually comprises four distinct species. The finding, based on integrative analyses of morphology, multi-locus genomic data, and Bayesian species delimitation, underscores the role of "sky island" geography in driving plant speciation and suggests that biodiversity across the Qinghai-Xizang Plateau may be substantially underestimated.

Researchers have developed Fe-doped carbon composite catalysts that significantly enhance the thermal decomposition and combustion performance of the energetic molecular perovskite DAP-4. By tailoring the loading of iron oxide nanoparticles on carbon substrates, the study demonstrates accelerated decomposition kinetics, reduced ignition barriers, and intensified combustion, providing a promising catalytic strategy for improving the energy-release efficiency of next-generation molecular perovskite energetic materials.

A new review highlights how microneedle technologies are evolving from a promising concept into a next-generation platform for precision monitoring and rehabilitation. The authors summarize recent advances in materials, sensing, drug delivery, and intelligent integration, while also identifying challenges such as manufacturability, validation, safety, and technological accessibility that must be addressed to make microneedle systems more inclusive and widely usable.
