A review published in SCIENCE CHINA Earth Sciences synthesizes current knowledge of nitrous oxide (N₂O) production by marine planktonic ammonia-oxidizing archaea (AOA), an important microbial group involved in ocean nitrification. The authors summarize the potential metabolic pathways of AOA-derived N₂O and examine how environmental factors including oxygen, temperature, pH, substrate availability, and organic carbon regulate this process. The review highlights the need to understand multifactorial effects of ocean warming, acidification, and deoxygenation to better predict marine N₂O emissions under future climate change.

Lithium cobalt oxide (LiCoO₂, LCO) stands as one of the most representative cathode materials in lithium-ion batteries. The improvement in energy density of LiCoO₂ is essentially achieved by increasing the charge cut-off voltage. However, under high-voltage conditions, the electrolyte solvent molecules undergo severe oxidative decomposition at the cathode interface. Moreover, a series of issues including transition metal dissolution, oxygen release, and deteriorated thermal stability, have become bottlenecks that severely restrict its practical application.

To address this challenge, Prof. Yang Sun (Sun Yat-sen University), Associate Researcher Maolin Yang (Xiamen University), Professors Qiaobao Zhang (Xiamen University), Yu Qiao (Xiamen University), and Academician Shi-gang Sun (Xiamen University) have proposed a novel strategy to stabilize high-voltage LiCoO₂ cathodes by coating them with a conformal zeolite layer using a scalable high-speed solid-phase mechanofusion technique. The sub-nano channels of zeolite enable complete Li⁺ desolvation, creating a locally supersaturated electrolyte that suppresses solvent decomposition. The Zeolite@LCO cathode achieves ~83% capacity retention after 300 cycles at 4.8 V and stable operation at 5.0 V, with significantly enhanced thermal safety. This work provides a translatable paradigm for high-energy-density lithium-ion batteries. This work was recently published online in Science Bulletin.

A study in Geodesy and Geodynamics used satellite radar to examine the November 2025 Hayli Gubbi eruption in Ethiopia’s Afar Depression. Researchers combined NISAR’s left-looking radar with Sentinel-1’s right-looking observations to reconstruct three-dimensional ground movement. Although the eruption occurred at Hayli Gubbi, the strongest deformation was detected at Erta Ale, where the summit crater partially collapsed and the ground sank inward. Modeling linked this to two shallow dikes beneath Erta Ale, both about 1 km deep. The event also reactivated nine nearby faults. Compared with a larger eruption earlier in 2025, the November event was more localized and relied mainly on shallow magma storage.
