Advancements in social media and communications technology has made underaged individuals increasingly vulnerable to online sexual exploitation. The Hong Kong Polytechnic University (PolyU) initiates a research project that seeks to incorporate the perspectives of children and adolescents in understanding the issue of online sexual exploitation of children (OSEC). This project has received funding support from the Research Grants Council (RGC) Humanities and Social Sciences Prestigious Fellowship Scheme (HSSPFS) 2025/26, with total grant of HK$503,000.

As power systems evolve to accommodate rising levels of renewable energy, traditional grid-following converters (GFLs) are no longer sufficient to ensure grid stability. Researchers from Imperial College London and Tsinghua University, led by Dr. Fei Teng and Mr. Guoxuan Cui, conduct a comprehensive techno-economic analysis of how to determine the optimal penetration of grid-forming converters (GFMs) required for future power networks. Their findings highlight how coordinated planning and dynamic operational control strategies can enable cost-effective and stable operation of “new-type power systems”.

Wild polyploid strawberries hold clues to how plants evolve and adapt to harsh environments.

A novel deep learning–based framework that dramatically improves the accuracy of forecasts, even when data are limited. The task involved using past atmospheric variables to predict five key surface weather indicators—including temperature, wind, and precipitation—every 6 hours for the next 5 days.

A zinc-assisted strategy was employed to synthesize honeycomb-like micro-nano porous Fe-N/C catalysts with asymmetric FeN₃Cl sites, which show excellent ORR (oxygen reduction reaction) performance and promote applications in energy catalysis.

The study showed that the four clusters of ETCs possessed significant differences in transition duration, location, and mechanism. Recurving ETCs predominantly underwent transition during their track recurvature from northwest to northeast.
