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.

A high-level South African delegation led by Professor Blade Nzimande, Minister of Science, Technology and Innovation (DSTI), visited the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) to explore new approaches of collaboration in space technology and its applications. The 23-member delegation included senior DSTI officials as well as representatives from the South African National Space Agency (SANSA) and other key institutions.
