A new study led by Prof. ZHAN Xiangjiang from the Institute of Zoology of the Chinese Academy of Sciences has confirmed that fecal samples can yield reliable genomic data and uncover the genetic mechanisms driving the recovery of this critically endangered species.

Scientists from the Qingdao Institute of Bioenergy and Bioprocess Technology of the Chinese Academy of Sciences have developed a novel computational tool, RamEx, designed to resolve the computational bottleneck in high-throughput microbial Ramanomics.

Researchers led by Prof. CHEN Yushun from the Institute of Hydrobiology (IHB) of the Chinese Academy of Sciences, along with domestic and international collaborators, have revealed that the Yangtze River fishing ban has not only halted the 70-year decline in fish resources but has also triggered an initial recovery.

A research group led by CAS member Prof. HE Shunping from the Institute of Hydrobiology of the Chinese Academy of Sciences, along with Prof. Thomas J. Near's group from Yale University, revealed the genomic mechanisms underlying the slow morphological changes in fish from the order Lepisosteiformes.

A research team from the National Time Service Center has investigated critical trade-offs in the design of broadcast ephemeris for low Earth orbit navigation satellites, offering new guidance for the development of next-generation positioning, navigation, and timing (PNT) systems.

Drawing inspiration from natural photosynthesis, a research team from the Institute of Earth Environment of the Chinese Academy of Sciences, has developed a universal approach to co-convert carbon dioxide and water.

Researchers from the Aerospace Information Research Institute of the Chinese Academy of Sciences, in collaboration with the International Research Center of Big Data for Sustainable Development Goals and Aarhus University in Denmark, have conducted the first nationwide assessment of how different categories of protected areas contribute to aboveground forest carbon density.

A research team led by Prof. ZHAO Bangchuan from the Hefei Institutes of Physical Science, in collaboration with Prof. XIAO Yao from Wenzhou University, developed a composition gradient strategy to precisely regulate the internal stress distribution and electronic structure of Li-rich Mn-based cathode materials.

A study led by Prof. ZHU Zhengjiang from Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences developed an ion mobility-resolved mass cytometry technology for single-cell metabolomics. This method achieved high throughput while maintaining deep coverage by integrating data acquisition with advanced processing strategies.

A research team led by Prof. YUAN Junying from the Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences elucidated the regulatory mechanism of late-onset Alzheimer’s disease (LOAD) risk gene INPP5D in microglial RIPK1 activation, and uncovered a new molecular link between neuroinflammation and LOAD with amyotrophic lateral sclerosis comorbidity.

A decade-long study has revealed that rising atmospheric CO₂ and warming work together to reduce the availability of phosphorus (P) in rice-upland rotation systems, which could threaten future food security. Led by researchers from the Institute of Soil Science, the study shows that warming plays a dominant role in redirecting phosphorus into less accessible soil pools.

A new study led by Prof. FENG Xiaojuan from the Institute of Botany reports that climate warming can increase soil carbon accumulation in boreal Sphagnum peatlands by boosting plant productivity, protecting iron, and inhibiting microbial decomposition. These responses contrast sharply with warming-enhanced soil carbon mineralization—the process by which carbon is released as CO₂—in boreal forests and tundra.

Researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences investigated the spatial distribution characteristics of the PhoD gene and its environmental driving factors in tropical and subtropical forests. They revealed that the abundance of PhoD was primarily shaped by elevation, soil pH, and calcium availability.

Researchers from the Hefei Institute of Physical Science of the Chinese Academy of Sciences have identified a key molecular module that regulates rice plant architecture, providing valuable genetic resources and regulatory modules for molecular breeding.

A research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a fast, multiplatform-compatible detection network that can "see" gas leaks in three dimensions.

Researchers from the Yunnan Observatories of the Chinese Academy of Sciences have conducted a new study on the temporal evolution of the afterglow from gamma-ray burst GRB 240825A. The study offers new evidence to better understand the physical environment surrounding gamma-ray bursts and provides insights into the mechanisms that govern their afterglow emission.

A research team led by Prof. CHONG Kang from the Institute of Botany, in collaboration with Prof. GUO Zifeng's research group, has identified a molecular regulatory module that controls flowering time in wheat, providing key genetic targets for improving and adapting wheat cultivars.
