Researchers propose a novel mechanism for non-reciprocal optical devices without magnetic fields through nonlinear non-reciprocal susceptibility. They experimentally achieved self-induced isolation of optical signals, demonstrating high isolation ratio (63.4 dB), wide bandwidth (2.1 GHz), and low insertion loss (1 dB). The innovation enables passive isolation through asymmetry cavity, allowing a weak signal to control stronger backward laser. This advancement has implications for topological photonics and quantum information transfer.

Optical sectioning enables precise 3D imaging by extracting signals in focus and eliminating out-of-focus backgrounds. Scientists in China review various optical sectioning methods from the perspective of off-axis and coaxial imaging, assess the performance, and provide guidance on their applications. Finally, it discusses the advantages of off-axis separated detection over coaxial imaging and the versatility of a single system to accommodate diverse sectioning methods, potentially revolutionizing 3D bioimaging.

A new study explores the integration of biopolymers with polyacrylic acid hydrogels, highlighting their potential applications in bioresources and bioproducts. This research offers insights into the development of sustainable and functional biomaterials for various fields, including flexible electronics and biosensing.

The Hong Kong Polytechnic University (PolyU) is committed to advancing green technology to help tackle the pressing need for global sustainability.

Researchers have introduced an innovative surgical technique for treating bladder cancer that could revolutionize the field of urological oncology.

A research team led by Prof. PAN Jianwei, Prof. WAN Zhensheng and Prof. DENG Youjin from the University of Science and Technology of China (USTC) observed counterflow superfluidity in two-component Mott insulator for the first time.

In a groundbreaking study led by Dr. Ying Chen and her team from Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, researchers have uncovered a novel mechanism behind endothelial dysfunction in sepsis-induced acute respiratory distress syndrome (ARDS). This study, which has significant implications for the treatment of sepsis and its complications, demonstrates how glycolysis-induced histone lactylation drives endothelial cell (EC) activation and promotes lung injury in sepsis.

Recently, a team of Chinese researchers led by Professor WU Yuchen at the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences has made significant strides in overcoming these challenges. The team has developed a novel method for the remote epitaxial growth of continuous crystalline perovskite thin films. This advance allows for seamless integration into ultrahigh-resolution micro-LEDs with pixels less than 5 μm.

Female sexual dysfunction (FSD), a condition affecting women's sexual arousal, desire, orgasm, or pain, has been identified as a hidden epidemic in China with a higher incidence in rural areas compared to urban ones. A four-year prospective cohort study provides a detailed analysis of FSD's incidence and associated risk factors, shedding light on the need for targeted public health strategies. The research involved a nationally representative sample of women from six provinces in China, capturing a diverse range of geographic and socioeconomic regions. The study utilized the Female Sexual Function Index (FSFI), a widely recognized tool for evaluating sexual dysfunction, to assess participants at baseline and during the follow-up period.
