A new review brings together research on geopolitical tensions, meteorological disasters, regional environmental degradation, supply chain disruption, systemic financial instability, and technology-mediated societal and institutional risks. It shows how shocks can spread through interconnected political, economic, ecological, technological, and social systems, and outlines a flexible cycle of risk identification, assessment, management, and adaptive monitoring supported by international cooperation.

Using MODIS observations from 2003 to 2024, researchers evaluated candidate regions and seasonal windows for marine cloud brightening (MCB) worldwide by examining how key cloud properties varied with aerosol optical depth (AOD). Among five representative ocean regions, the North Pacific during boreal autumn (SON) showed a favorable coordinated pattern: cloud fraction and cloud optical thickness were positively sensitive to AOD, whereas cloud droplet effective radius was negatively sensitive. The study provides an observational basis for further evaluation of MCB candidate regions and seasonal windows. The findings were published in Science China Earth Sciences.

Many vitreoretinal disorders, including retinal detachment (rhegmatogenous, exudative, or tractional), macular holes, proliferative vitreoretinopathy, diabetic retinopathy, and vitreous hemorrhage, often require vitrectomy with retinal repair, followed by intraocular tamponade to stabilize the retina and preserve ocular integrity. The tamponade agents most used in clinical practice are expansile gases and silicone oil. Although these materials can effectively support postoperative retinal reattachment, they remain limited in terms of long-term stability and biosafety. Complications such as cataract formation, elevated intraocular pressure, intraocular inflammation, and retinal injury associated with silicone oil emulsification may still occur. To address this challenge, Prof. Jianhai Yang and Prof. Wenguang Liu (Tianjin University), together with Prof. Xiaorong Li and Prof. Xiaoli Xing (Tianjin Medical University Eye Hospital) developed an injectable zwitterionic polymer hydrogel based on poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC).

Since the Last Glacial Maximum, the Earth’s climate system has undergone pronounced temperature and hydroclimatic changes. This long-term evolution provides an important context for understanding the natural background of modern climate change and the response of the climate system to external forcing. Over China, climate evolution exhibits substantial regional heterogeneity under the combined influence of the East Asian monsoon and the complex topography of the Tibetan Plateau. Using high-resolution dynamical downscaling simulations, Professor Liang Ning and colleagues at Nanjing Normal University systematically investigated millennial-scale climate evolution over China since the Last Glacial Maximum. The results show that the regional climate model provides a more detailed representation of the spatial heterogeneity of temperature and precipitation associated with complex terrain. In addition, the contrasting Holocene trends of summer cooling and winter warming over northern China, the Tibetan Plateau, and northwestern China provide a new seasonal perspective on the Holocene temperature conundrum between proxy reconstructions and climate-model simulations. The study was published in the 2026 Issue 8 of the Chinese and English editions of SCIENCE CHINA Earth Sciences.
