In recent years, significant advancements in educational technology, particularly the rise of online learning platforms, have transformed the way students engage with educational content. This study developed an intelligent digital human-based teaching system that leverages the capabilities of large language models to provide personalized, interactive, and real-time support.

A synthesis of four studies showcasing how to use artificial intelligence technologies to design collaborative learning scenarios that have implications.

A collaborative research team from institutions including China Agricultural University and Solomon Islands National University has addressed this question through in-depth analysis using a multi-country general equilibrium model. By leveraging trade data from 2001 to 2022 and combining it with a structural multi-country trade model, the team simulated the impact of China–Africa agricultural trade liberalization on the welfare and food security of both parties. The related paper has been published in Frontiers of Agricultural Science and Engineering (DOI: 10.15302/J-FASE-2025617).

Recently, a study led by Professor Qiran Zhao from the College of Economics and Management, China Agricultural University, for the first time incorporated physical fitness tests into the evaluation system. By analyzing the implementation effect of China’s Nutrition Improvement Program (NIP) for rural compulsory education students, the study provides a new perspective for optimizing SFPs worldwide, especially in African countries.

Transposable elements play a significant role in regulating gene expression and genome architecture, influencing development, immunity, aging, and disease progression. A study from researchers in China reviews these elements' molecular mechanisms and clinical implications, highlighting their potential as biomarkers and therapeutic targets for conditions like cancer, neurodegenerative, and autoimmune diseases. This research opens pathways for personalized medicine by targeting disease-specific transposable element signatures.

Recently, Professor Xu Tian from the College of Economics and Management at China Agricultural University, in collaboration with Mosses Lufuke from the Department of Economics at the University of Dodoma in Tanzania, uncovered the underlying reasons through data analysis. The related article has been published in Frontiers of Agricultural Science and Engineering (DOI: 10.15302/J-FASE-2025645).

A recent study published in National Science Review has estimated the global biological nitrogen fixation from natural terrestrial ecosystems as 78.2–89.8 Tg N yr^-1, revealing an underestimation of this flux up to ~18% in existing Earth System Models (ESMs). The findings suggest many ESMs may overstate the nitrogen limitation or vegetation internal nitrogen recycling efficiency.

The enhancement of energy density in lithium-ion batteries often comes with a decrease in cycle life. Sulfur-based lithium-ion batteries possess theoretical advantages of low cost and high specific energy, but currently, their energy density is limited and cycle life is short. Now, Huang's team has achieved simultaneous improvement in energy density and cycle life of sulfur-based batteries through ultra-low N/P ratio design and anion-mediated electrolyte engineering in the journal of Science Bulletin, unlocking the potential of sulfur-based lithium-ion batteries.
