Researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences have discovered two new species of Begonia in the karst region of Guangxi, China. The two species, Begonia renkunii and Begonia tianyangensis , were identified from specimens collected during field surveys in Baise City and have been described in the journal Phytotaxa . The researchers collected

Large-scale recording of multiple dynamic behaviors and quantitative neurochemical concentrations with high spatiotemporal resolution is critical to understand complex brain functions. Two-photon microscopy (TPM) is the excellent choice for brain function imaging because of its high resolution, deep tissue penetration, and favorable biosafety. However, current TPM is limited by a restricted field-

Triplet excited states of organic molecules play essential roles in photocatalysis, photodynamic therapy, photon upconversion, and organic optoelectronic applications. However, achieving efficient triplet generation in purely organic molecules remains challenging because of their intrinsically weak spin–orbit coupling. Spin–orbit charge-transfer intersystem crossing (SOCT-ISC) has emerged as a pro

Solvent molecules can act as gatekeepers inside zeolite catalysts, limiting the space available for larger reactants to reach internal active sites. A recent study has shown that simply regulating where these solvent molecules reside can significantly enhance catalytic performance—without changing the catalyst's intrinsic micropore structure. The study, led by Assoc. Prof. XING Jiacheng, Prof. XU

Understanding how domestication reshapes brain structure and function remains a fundamental question in evolutionary biology. The hippocampus is a key brain region involved in memory and stress regulation, and it has been thought to undergo "simplification" during domestication. However, the cellular mechanisms underlying these changes remain poorly understood. In a study published in PNAS on Sept

Cilia and flagella are antenna‑like organelles that project from the cell surface and are widely distributed from unicellular eukaryotes to mammals. Motile cilia must beat in a coordinated manner to generate productive fluid flow and drive cell motility, which is essential for processes such as sperm propulsion, mucociliary clearance in the airways, and cerebrospinal fluid circulation. Now, a rese

Noninvasive monitoring of cortisol is important for characterizing circadian regulation and physiological responses to exercise and stress. Sweat has provided an alternative to laboratory testing, but existing wearable cortisol platforms often rely on complex microfluidic collectors, electronic readout modules, or dedicated instruments. It is needed to integrate rapid sweat acquisition, selective

A research team from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences, together with collaborators, has revealed a new mechanism by which spatially ordered heteroatoms induce bulk polarization in nonpolar semiconductor photocatalysts, offering a promising pathway to overcoming the long-standing challenge of efficient charge separation for solar water splitting. Their findin

Establishing a quantitative structure-property relationship is essential for understanding and optimizing the performance of elastomers. In a new study published in Physical Review Letters , researchers have developed a theoretical framework that quantitatively connects the macroscopic mechanical response of unentangled elastomers to the mechanics and conformations of individual polymer strands.

According to a study by researchers from the Institute of Applied Ecology (IAE) of the Chinese Academy of Sciences (CAS) and their domestic and international collaborators, forest recovery on land affected by fires, harvesting, and other disturbances has been the main contributor to China's forest carbon sink over the past three decades. The study was published in Nature Geoscience on August 17. A
