Recently, the archaeometry team from University of Chinese Academy of Sciences, in collaboration with National Center for Archaeology, Key Laboratory of Archaeological Sciences and Cultural Heritage, Chinese Academy of Social Sciences, Institute of Archaeology of the Chinese Academy of Social Sciences, and Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, utilized paleoproteomic technology to reveal that the feather decoration unearthed from Tomb No. 1 at Wuwangdun (Tomb of King Kaolie of Chu) of the late Warring States period (the late 3rd century BCE) were crafted from the feathers of multiple bird species, and that the used animal glue originated from the extinct short-horned water buffalo (Bubalus mephistopheles). This research not only fills the gap in the scientific analysis of archaeological feather remains in China but also extends the known survival time of the short-horned water buffalo by at least 700 years. The related findings were published in Science Bulletin entitled "Proteomic characterization of feather decorations and extinct buffalo glue during early Iron Age China".
For more than a decade, a fundamental mystery has surrounded graphene—the one-atom-thick “wonder material” known for its exceptional strength, conductivity, and transparency. Despite its seemingly simple structure, one basic question has remained unresolved: does graphene attract water, or repel it?
The answer has proven surprisingly elusive. In some experiments, water droplets bead up on graphene, suggesting a hydrophobic (water-repellent) surface. In others, water spreads out, implying hydrophilic (water-attracting) behavior. This contradiction has fueled a long-running scientific debate and created uncertainty for applications such as desalination membranes, hydrogen fuel cells, and nanoelectronic devices, where precise control of water at interfaces is essential.
A research team led by Director CHO Minhaeng and Professor Stefan RINGE at the Center for Molecular Spectroscopy and Dynamics within the Institute for Basic Science, in collaboration with Korea University, has now resolved this puzzle. Using machine-learning–enhanced molecular simulations, the researchers demonstrate that pristine graphene is intrinsically hydrophobic and microscopically not wetting transparent.Hydrogen peroxide is a widely used chemical essential to water treatment, disinfection, and green manufacturing, yet its conventional production relies on energy-intensive and centralized processes. Recent research highlights an emerging electrochemical route that generates hydrogen peroxide directly from oxygen and water under ambient conditions. Central to this approach is the use of noble metal-free single-atom electrocatalysts, where isolated metal atoms embedded in nitrogen-doped carbon precisely steer oxygen reduction toward the desired two-electron pathway. By combining atomic-scale catalyst design with advanced reactor engineering, this strategy offers a cleaner, safer, and more flexible way to produce hydrogen peroxide on demand, opening new possibilities for decentralized and sustainable chemical manufacturing.
Programmable optical particle transport based on structured light plays a crucial role in microscale manipulation. Scientists in China have developed a multi-prior physics-enhanced neural network (MPPN-RW) that enables high-fidelity generation of arbitrary optical conveyor belts without training data. This technique allows precise and stable transport of microparticles along complex trajectories, offering new opportunities for optical micromanipulation, targeted delivery, and reconfigurable light-field engineering.
This study demonstrates an experimentally feasible scheme to achieve robust strong coupling between a single quantum dot and a plasmonic nanocavity integrated with a one-dimensional photonic crystal cavity. A Rabi splitting exceeding 170 meV is observed in dark-field scattering spectra. We further demonstrate that the stronger localized electric field within the hybrid cavity not only enhances the coupling strength but also, owing to the more uniform field distribution, reduces the sensitivity of the coupling strength to the quantum dot position within the cavity, thereby improving the uniformity of the device's coupling performance. The robustness of such a strongly coupled system will advance the development of room-temperature quantum devices based on single emitters for potential applications.
