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.

A Chinese research team has developed a new remote-sensing satellite model, which has for the first time achieved the high-precision, dynamic calculation of CO2 emissions from large coal-fired power plants, providing a new solution for global carbon emissions monitoring.

Chengdu, China – June 11, 2025 – The "Space Information Science and Technology for Building the Innovation Road" Forum opened today in Chengdu, injecting powerful technological momentum into the sustainable development of the Belt and Road Initiative (BRI). Convened during the second Belt and Road Conference on Science and Technology Exchange and organized by the Chinese Academy of Sciences (CAS), the forum gathered global experts to bridge scientific cooperation and showcase cutting-edge applications of big data for global sustainability.

A research team from the Aerospace Information Research Institute at the Chinese Academy of Sciences has proposed a breakthrough in vacuum sensing. Their study (DOI: 10.1038/s41378-025-00937-z), published on May 21, 2025, in Microsystems & Nanoengineering, details a novel micro-electro-mechanical systems (MEMS)-based sensor that integrates mode-localization and traditional resonance mechanisms on a single chip. Designed to toggle between modes depending on pressure levels, the sensor provides high resolution and stability across a wide pressure range. This design not only improves measurement performance but also reduces sensor size and dependency on gas types—key for harsh environments.
