In a paper published in SCIENCE CHINA Earth Sciences, a research team conducted a comprehensive analysis of mineralogical and geochemical records, along with carbon consumption fluxes, from sediments at Site CSDP-1 in the South Yellow Sea obtained by the Chinese Continental Shelf Drilling Program. They quantitatively reconstructed the 600,000 year evolutionary history of silicate weathering and its carbon consumption rates in the Yellow River basin-shelf system. The study proposes that the mid-latitude shelf region was an underestimated active silicate weathering carbon sink during glacial periods. It thus provides a novel perspective for understanding the mechanisms of glacial-interglacial climate evolution on Earth.

A paper published in National Science Review brings together evidence on how plastics are produced, released, transported and transformed, and how they affect ecosystems, human health and Earth-system processes. It argues that lasting solutions must address the full plastics life cycle, with upstream prevention and safer design supported by reuse, recycling, pollution control, monitoring, and coordinated global governance.

A team led by researchers at Peking University Cancer Hospital & Institute reports that combining targeted KRAS inhibition with CTLA-4 immune checkpoint blockade overcomes the immunosuppressive microenvironment that renders KRAS-mutant gastric adenocarcinoma resistant to PD-1 immunotherapy. In a genetically faithful, immunocompetent mouse model of KRAS^G12D-driven gastric cancer, the combination suppressed TGF-beta signaling, impaired regulatory T cell function and elicited effective anti-tumor immunity. The study, published in Science China Life Sciences, provides a preclinical rationale for CTLA-4-based combination immunotherapy in this molecularly defined subset of patients.

Researchers at Fudan University have developed a crosslinked potassium polyacrylate skin membrane that lets microrobots generate electricity by walking on metal or silicon surfaces. The membrane uses atmospheric moisture and oxygen to convert environmental chemical energy into power, achieving 133 mW cm⁻² on zinc. It also senses substrate material and roughness, enabling active energy pursuit. The system powered over 10,000 walking steps and remained stable after 1,000,000 steps.

Rock weathering is an important process regulating atmospheric CO₂ concentrations and long-term climate evolution, yet how enhanced erosion affects rock weathering and its carbon effects remains poorly understood. Focusing on the Lancang River basin on the southeastern margin of the Tibetan Plateau, the authors quantitatively reveal the differential responses of silicate, carbonate, and sulfide weathering to changes in erosion. The results show that, as erosion intensifies, silicate weathering rates decrease while sulfide oxidation rates increase, causing weathering in the basin to tend toward a net carbon source. The related findings have now been published in Science China Earth Sciences.
