The study follows the guidelines of the Care and Use of Laboratory Animals published by the US National Institutes of Health (NIH Publication No. 85 − 23, revised in 1996). All animal experiments were approved by the Institutional Animal Care and Use Committee (IACUC) of Jinan University and Sun Yat-sen University Cancer Center. Balb/c nude mice used in this study were ordered from the Charles River Company (Beijing, China) and housed under specific-pathogen-free conditions.

The high penetration of weather-dependent renewable energy sources (WD-RESs) such as wind and solar has raised concerns about the security of electric power systems during abnormal weather conditions. The role of RESs has been discussed in worldwide blackout events, yet remains controversial. In this study, we find that although WD-RESs are non-dispatchable and weather sensitive, blackout intensities and extreme weather vulnerability are mitigated in high-penetration WD-RES grids. The causal effects of WD-RESs on blackouts generally decrease in high-penetration WD-RES power systems, and WD-RESs are not mainly responsible for the occurrence of blackouts in extreme weather conditions. The results of our research contribute to the debate on RES integration and power system security, offer a guide for the study of power system resilience and provide a reference for the ambitious high-penetration RES goals of the future. Renewable energy sources (RESs) are weather sensitive, raising questions about the vulnerability of high-penetration weather-dependent RES grids during extreme weather events. Here the authors find that blackout intensities and extreme weather vulnerability are mitigated in high-penetration weather-dependent RES grids.

Graphical Abstract Dynamic Anticounterfeiting In the study by Qiwei Zhang, Haiqin Sun, and co-workers (article number 2300925), a time-dependent color-tunable luminescent material (Na2BaSiO4:Eu) is unlocked based on the inherent luminescence of Eu2+/Eu3+ through a light stimulus. The blue luminescence of Eu2+ gradually degrades by 365 nm light irradiation, accompanied by a reversibly emitted color change between blue and red by alternating light or thermal stimuli.
