A new review links three forces shaping osteoarthritis: mechanical stress, integrin signaling, and integrin endocytosis. The authors argue that integrin trafficking can reprogram where and how long signals persist in joint cells, helping explain stage-dependent effects and pointing to new biomarker and therapy ideas, from small molecules to RGD biomaterials and MSC-based approaches.

To address the challenge of wireless signals being blocked by seats or passengers, a team led by Professor Jingjing Zhang from Southeast University and Professor Yu Luo from Nanjing University of Aeronautics and Astronautics developed a transparent metasurface smart window. Utilizing "self-accelerating" and "self-healing" Weber beams, the technology allows signals to bypass obstacles and recover automatically. Experiments show an average signal power increase of 8.37 dB, providing a practical solution for 5G vehicular communications.

Researchers have developed a new brain–computer interface that records neural signals from the brain’s lateral ventricle, a fluid-filled cavity traditionally used only for clinical drainage. Using a lantern-inspired expandable electrode, the system delivers stable, high-quality recordings for months and decodes memory-guided decisions with up to 98% accuracy in rats. The approach reduces immune response compared with conventional cortical implants and opens a new route for long-term, minimally invasive brain–machine interfaces.
