In a world where urban traffic congestion and environmental concerns are escalating, innovative solutions are crucial for creating sustainable and efficient transportation systems. A groundbreaking study led by Hongbin Ma from the National Key Lab of Autonomous Intelligent Unmanned Systems at the School of Automation, Beijing Institute of Technology, introduces a pioneering approach that combines Long Range (LoRa) technology with distributed machine learning to optimize network connectivity for green and intelligent transportation systems.

In March 2025, an English academic journal "Safety Emergency Science" was officially launched.

Quasi-particles are collective quantum elements of condensed matter. They are foundationally important for understanding physics of materials and for technological applications of semiconductors. Using ultrafast optical pump-probe technique, scientists discovered a series of new spectral features that are not attributable to existing quasi-particles. By using advanced quantum many-body theories, these spectral features could be uniquely explained by the existence of a new quasi-particle called quadruplon, a genuine four-body composite particle, different from the known bi-exciton.

Cancer remains a leading cause of death globally, with lung cancer being particularly lethal. Despite advancements in diagnostics and therapies, the five-year survival rates for advanced tumors have seen minimal improvement, largely due to therapeutic resistance. This resistance can be genetic or nongenetic, with the latter being less understood but increasingly recognized for its role in treatment failure. Non-genetic resistance is associated with resistant cancer cells that have innate or acquired drug resistance traits. These cells are often found in heterogeneous tumors and include cancer stem-like cells (CSCs), cells undergoing epithelial-to-mesenchymal transition (EMT), partial EMT cells, and drug-tolerant persisters (DTPs). NOTCH signaling plays a crucial role in tumorigenesis and therapeutic resistance, with its activation linked to drug resistance in various cancers.

This study demonstrates that the activities of soil extracellular enzymes were significantly altered in the alpine meadow, but not significantly in the swamp meadow, which coincided with the SOC content of these grasslands.

 Research team proposed DeepSwarm, a collective deep learning framework integrating swarm intelligence for bidirectional optimization of data acquisition and processing. It improves accuracy and resource efficiency in IoT scenarios, showing significant results in video analysis and federated learning.

The High Energy Photon Source (HEPS), China’s flagship synchrotron radiation facility, has officially begun its joint-commissioning phase after successfully completing photon beam commissioning, the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences, which developed the facility, announced on March 27 in Beijing.

A research team led by Prof. WEN Liping from the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences has developed a biomimetic adsorbent that can attract and hold uranium ions. The inspiration for this adsorbent is the natural porous structure of the spiky, globular fruit of the Chinese sweet gum tree, Liquidambar formosana.

Transition metal valence state, a key property steering heterogeneous catalysis, has remained underexplored for its role in tuning S cathode kinetics in Li–S batteries. This study reported that CuO and Cu₂O particulate catalysts exhibited distinct interactions with sulfur species, dictating the kinetics of sulfur reduction reactions. While Cu²⁺ enables direct (poly)thiosulfate redox, both Cu²⁺ and Cu⁺ indirectly modulate lithium (poly)sulfide chemisorption by altering O^2- reactivity and Li bond strength. CuO with stronger interactions enabled faster sulfur reduction reaction kinetics, achieving enhanced Li–S battery performance. This work expands the scope of metal-valence-state effects in catalysis and offers an unconventional strategy to optimize Li–S battery performance via indirect Li-bond regulation.
