Southwest China's Xizang Autonomous Region has set a new national record in terms of corn yields, after two demonstration fields in a village of Nyingchi City recently recorded harvest yields of 1,842.72 kg and 1,699.96 kg per mu (about 0.067 hectares), respectively.

The orbiter of China's Mars mission Tianwen-1 has successfully observed an interstellar object, coded 3I/ATLAS, using its high-resolution camera, according to the China National Space Administration (CNSA). During the observation, the spacecraft was about 30 million kilometers from 3I/ATLAS, making it one of the closest observations by a probe of this interstellar object. The observation represents an important extended mission for Tianwen-1 and serves as a valuable technical test for China's Tianwen-2 mission, which was launched in May to collect samples from a near-Earth asteroid and explore a main-belt comet.

The China-developed world’s first pontoon two-seat electric seaplane, the RX1E-S, carried out an ecological patrol on Tuesday over the water areas of Yanqing District in Beijing and the Guanting Reservoir in north China’s Hebei Province. Featuring a maximum cruising speed of 157 km/h and an endurance of 1.5 hours, the aircraft can reduce the patrol time for water areas in Yanqing from two days to just five minutes and shorten the inspection of the 238-sqkm reservoir to 20 minutes.

China has called for the broader application of AI in its health sector over the coming years, with intelligent diagnosis and treatment assistance set to be universal in basic terms across the country's primary-level medical institutions by 2030, including community and village clinics, according to a document released on Tuesday.

Chinese scientists have completed the ground tests of an inflatable, reconfigurable module for a novel space manufacturing platform. The breakthrough module has an innovative design that is intended for launch in a tightly folded configuration and inflates once in orbit to form a large, stable workspace. Test images have revealed that the expanded module forms a cylindrical structure over 2 meters in diameter, making it an ideal candidate for future space-based manufacturing, including areas such as biopharmaceuticals, 3D printing and the production of novel materials.

China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) achieves breakthroughs in key domestic technologies, data release: - Successfully employed 4,000 domestically produced specialized astronomical broadband optical fibers in its focal plane to link with spectrographs, enabling the simultaneous observation of 4,000 celestial objects -- a cornerstone of its large-scale spectroscopic survey capabilities. - Upgraded its fiber-positioning system from an open-loop to a closed-loop detection system, improving the system's average efficiency by approximately 20%. - Achieved the domestic development of displacement actuators, which serve as core components of LAMOST's innovative active optics system. - Released a total of 28.07 million spectra and 11.59 million sets of stellar parameters as of October, retaining its status as the world's leading producer of astronomical data. - More than 1,800 users from 300 institutions around the world are making use of the data. These users have downloaded roughly 170,000 GB of data, and the data-release portal has been accessed 3.73 million times.

China's PALLAS-1 reusable liquid rocket on Tuesday successfully carried out an offshore trial run for its first-stage propulsion system in east China's Shandong, marking the completion of all major ground tests for the rocket and a step closer to its maiden launch. As one of China’s first reusable liquid rocket set to conduct orbital-class launches, PALLAS-1 is designed with at least 25 reuse cycles.

The return of China's Shenzhou-20 crewed spaceship, originally scheduled for Wednesday, will be postponed due to a suspected impact from tiny space debris. The impact analysis and risk assessment are under way, the China Manned Space Agency announced.

In a world first, Chinese doctors have performed a remote robotic subretinal injection surgery in south China’s Guangzhou, using a 5G-connected robot to treat a patient over 4,000 kilometers away in northwest China’s Urumqi. The entire remote surgery took less than seven minutes, with the network remaining stable and the robot responding smoothly without any tremor, marking a key leap from feasibility to practicality in the field of remote high-precision ophthalmic surgery in China.

Barbecue in space! 🍗China’s Tiangong Space Station has fired up its first-ever “space oven,” serving a freshly grilled chicken-wing feast to two crews of taikonauts on board. With smart temperature control and a system that keeps every crumb in check, the oven cooks smoke-free and grease-free and is built to operate up to 500 times in space, opening the door to more home-style meals for space journeys.

The 2-MW Thorium Molten Salt Reactor (TMSR) in northwest China's Gansu Province has successfully achieved the first-ever thorium to uranium nuclear fuel conversion and obtained valid experimental data following thorium fuel loading, making it currently the only operational molten-salt reactor in the world loaded with thorium fuel. This realization marks a milestone in TMSR development and confirms the technical feasibility of thorium utilization in a molten-salt reactor nuclear energy system. The project's ultimate goal is to construct a 100-MW demonstration project and realize its demonstration application by 2035.
