Findings from a major collaboration involving over 50 scientists from 31 research reveal that the world's oceans absorbed more heat in 2025 than in any other year since modern record-keeping began. Published in the journal Advances in Atmospheric Sciences, the report showed that the global ocean heat content in the upper 2,000 meters set a record for the ninth consecutive year, increasing by 23 zettajoules compared to 2024.

A team of Chinese and international scientists has uncovered the precise mechanism behind one of nature's most vital alliances: the partnership between legume plants and nitrogen-fixing bacteria. This finding has the potential to transform future agricultural practices. The discovery, published in the latest issue of Science, explains how plants and bacteria identify the perfect partner, paving the way for engineered crops that may one day need far less chemical fertilizer.

China has made progress in scientific data simulation for the Chinese Space Station Telescope (CSST), also known as the Xuntian Space Telescope, marking a crucial step in preparing for the country's flagship space astronomy facility. A collaborative Chinese research team built an end-to-end observation simulation suite for both the telescope's main optical system and various observation terminals.

By studying the detection data of China's first Mars rover, Zhurong, Chinese geologists have found that the Martian surface had still exhibited significant aqueous activity approximately 750 million years ago. This discovery shows that water existed on Mars several hundred million years longer than previously thought.

A novel experiment on the fundamental science of lithium-ion batteries has been carried out aboard China's Tiangong space station.

A team of Chinese scientists has demonstrated that simple, non-invasive sound therapy can produce significant and remarkably long-lasting biological changes in aged monkeys, offering new hope for a potential physical treatment for Alzheimer's disease. The study, published in the latest issue of the Proceedings of the National Academy of Sciences (PNAS), was led by researchers from the Kunming Institute of Zoology (KIZ) of the Chinese Academy of Sciences.

China's space station made steady progress in the development of space science, application experiments and technology tests in 2025, according to China's Technology and Engineering Center for Space Utilization (CSU) under the Chinese Academy of Sciences.

A novel experiment on the fundamental science of lithium-ion batteries has been carried out aboard China's Tiangong space station, according to the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences on Wednesday. This experiment, conducted by the three astronauts comprising the Shenzhou-21 crew, aimed to uncover the mechanisms behind battery performance by leveraging the unique conditions of space.

An industrial demonstration project which passed an acceptance review in Beijing on Tuesday can decompose hydrogen sulfide (H2S), a highly toxic industrial waste gas, into high-purity hydrogen and sulfur, offering an innovative pathway for green transformation in traditional industries such as natural gas, petrochemicals and coal utilization.

An asteroid has been officially named after Kuang Tingyun, a distinguished Chinese botanist renowned for her long-standing research on photosynthesis, the Institute of Botany under the Chinese Academy of Sciences (IBCAS) said Tuesday.

Nestled among the mountains by the sea in Huizhou, Guangdong province, one of the world's largest all-ion accelerators is poised to go into operation, helping China to be at the forefront of nuclear science. The High Intensity Heavy Ion Accelerator Facility (HIAF), which generated its first beam in October 2025 after seven years of construction, was developed by the Institute of Modern Physics at the Chinese Academy of Sciences.

A group of Chinese researchers has developed a three-dimensional (3D) electrical imaging method that directly reveals how defect passivation treatment improves the quality of perovskite films and related solar cell performance. The study was recently published in the journal Newton.

Researchers have identified a method to surpass the plasma density limit in experiments with the Experimental Advanced Superconducting Tokamak (EAST), known as the "artificial sun," providing a crucial physical basis for high-density operation in magnetic confinement fusion devices.

China's three deep-sea manned submersibles have completed 1,746 dives to date, the Institute of Deep-sea Science and Engineering under the Chinese Academy of Sciences said on Wednesday. The trio -- Fendouzhe (Striver), Shenhai Yongshi (Deep Sea Warrior) and Jiaolong -- is set to complete 314 dives this year alone, according to data released by the institute at a meeting in Sanya, south China's Hainan Province.

Since mid-July, the environmental authority stationed on Yongshu Reef in the Nansha Islands, along with researchers from the Chinese Academy of Sciences, has been continuously monitoring the nearshore waters of the reef and has observed dugongs, which are national first-class protected animals.

Step inside China's next-level giant "super lab," where scientists are pushing the limits by recreating the most extreme conditions on Earth, from ultra-low temperatures to ultra-high pressures and so on, all in one place and under one roof. This cutting-edge facility is designed to push the boundaries and become a global hub for groundbreaking research, unlocking breakthroughs that could reshape technologies, medicine, and quantum computing.

A research team from the Shenzhen Institutes of Advanced Technology (SIAT), Chinese Academy of Sciences, has uncovered a neuron-derived signaling mechanism that critically amplifies neurovascular damage following cerebral ischaemia. The findings have been published in European Heart Journal, one of the leading journals in cardiovascular research.

Of the four mice involved in a recent mission aboard China's space station, one female has now successfully birthed healthy offspring on Earth, the Technology and Engineering Center for Space Utilization (CSU) of the Chinese Academy of Sciences (CAS) has announced. The four mice were sent into space aboard the Shenzhou-21 crewed spaceship on Oct. 31, and were housed in a specialized habitat on the space station before returning to Earth on Nov. 14.
