BEIJING, Sept. 14 (Xinhua) -- Chinese researchers have developed a hybrid framework to trace sources and change of on-road carbon dioxide emissions in real time with 30-meter resolution, according to a research article recently published in the journal Sustainable Cities and Society.

On Sept. 6, the Fifth International Forum on Big Data for Sustainable Development Goals (FBAS 2025) opened in Beijing. The world's first large-scale artificial intelligence model designed to support the United Nations Sustainable Development Goals (SDGs) was unveiled.

Global scientists met in Beijing to discuss how big data can advance the United Nations' Sustainable Development Goals, emphasizing the need for global cooperation to speed up progress.

A Chinese-led team has reported a breakthrough in brain-computer interface (BCI) technology after completing the first-ever clinical trial to precisely locate deep-seated brain tumors using implanted microelectrode arrays. In the world's first trial of its kind, conducted by the Aerospace Information Research Institute of the Chinese Academy of Sciences and the First Affiliated Hospital of Harbin Medical University, a glioma patient experiencing speech difficulties due to tumor compression showed significant improvement in language ability after surgery guided by BCI technology. The core innovation lies in the BCI device, called "NeuroDepth," which provides real-time navigation for tumor boundary detection, enabling accurate resection while protecting healthy tissue. Unlike traditional electrodes that capture only surface signals, NeuroDepth can record activity from the cortex to deep brain regions and monitor neurotransmitters, offering more detailed data. "It has broken through the limitation of traditional neural electrodes, which could only detect signals from cortical based tumors," said Wang Mixia, an associate researcher of the Aerospace Information Research Institute. "Our electrodes can capture neural signals across the entire brain, from the cortex to subcortical regions and even deep brain structures. They are capable of not only detecting neuro-electrophysiological signals but also monitoring neurotransmitter signals, providing more precise information," Wang said. Researchers say the technology could advance treatment of gliomas and brain metastases, which are difficult to remove due to unclear boundaries. They also plan to expand applications, including BCIs to restore vision and hearing, and endovascular interfaces to support motor recovery in paralyzed patients.

BEIJING, July 30 (Xinhua) -- Chinese researchers have achieved a breakthrough in monitoring methane emissions from landfills, paving the way for more effective global emission reduction strategies. The study was published on Monday in the journal Nature Climate Change.

The Xixia Imperial Tombs in northwest China were officially inscribed on the UNESCO World Heritage List on July 11, 2025, during the 47th session of the World Heritage Committee held in Paris. This designation marks China's 60th World Heritage site and underscores the site's exceptional value in understanding the Tangut people, the Xixia Dynasty (Western Xia, 1038–1227), and the formation of China's unified multi-ethnic nation.
