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.
Artificial Intelligence (AI) can predict judicial decisions, but can it explain how they are legally jusitified, and can judges trust it? A Perspective in National Science Review argues that legal computing requires higher interpretability and reliability, and judicial values should be embedded into model and algorithm design. It outlines a value-guided framework within a “society–law–ethics–algorithms–data” system and identifies three scenario-specific applications: legislation, feedback-validated enforcement and trustworthy, human-centered adjudication. The Perspective further suggests that combining empirical learning with formal reasoning may offer a particularly promising path forward.
University of Phoenix has published a new white paper, Three Pillars for Embracing AI at University of Phoenix, by Christina Neider, Ed.D., and Marc Booker, Ph.D., outlining the University's institutional framework for integrating generative artificial intelligence (AI) across academic programs, student learning experiences, and institutional processes, policies and workflows while helping prepare working adult learners for an AI-enabled workforce. The white paper examines the role higher education institutions can play in helping learners develop the knowledge, skills and judgment needed to use AI effectively and responsibly. Drawing on University of Phoenix's generative AI implementation work, the authors share a scalable, three-pillar framework for higher education AI adoption aligned with workforce relevance and student success.
JMIR Publications released four feature News and Perspectives articles this week, covering developments in smart textiles, PMOS treatment in India, the FDA’s TEMPO pilot for regulating AI-enabled devices, and the ethical quandaries of using online forums in research.
