SJTU researchers propose a dynamic MCPV model and CZone mechanism, slashing memory footprint by 90%.

In a paper published in SCIENCE CHINA Earth Sciences, a team led by Professor Chuanfeng Zhao from Peking University presents a comprehensive review of global sea-land breeze research. The study systematically synthesizes recent advances in identification methods, key observational benchmarks, and the complex meteorological and non-meteorological factors that govern these coastal wind systems. The authors highlight that future breakthroughs will depend on improving spatiotemporal precision and clarifying how aerosols influence sea-land breeze dynamics through micro-physical mechanisms.

Researchers have developed a real-space topological strategy to stabilize fractional orbital angular momentum modes, which are normally unstable in free space. Inspired by quark confinement, the team used optical conformal mapping to stitch fractional phase structures into stable composite wave states. The mechanism was experimentally demonstrated on an elastic flexural wave platform and may offer new opportunities for wave manipulation in acoustics, photonics and on-chip information systems.

Chinese researchers led by Prof. Shen Liu from the Department of Orthopedics of the Shanghai Jiao Tong University School of Medicine have discovered that certain supporting cells expressing a protein marker called p16^INK4a, once associated with aging or stressed cells, were found to be key drivers of tendon healing. JMJD3, a molecular "switch," helped them turn on the repair genes. This pathway can be targeted to develop new treatment strategies for tendon injuries.

This work presents the first demonstration of a parallel heterodyne light-induced thermoelastic spectroscopy (PH-LITES) sensor for high-speed and high-sensitivity simultaneous multi-gas detection. By synergistically combining signal enhancement at the physical layer with intelligent decoupling at the information layer, the sensor achieves ppb-level simultaneous and fast multi-gas detection based on a single quartz tuning fork (QTF), providing an important reference for the future development of rapid and highly sensitive multi-gas sensing technologies.

In a post hoc analysis of 210 ICU-admitted patients from the French multicenter COMBAT cohort, nearly half of survivors of community-acquired bacterial meningitis still had unfavourable functional outcomes 1 year after intensive care. Hearing loss, depressive symptoms, and impaired physical quality of life were common, while fewer than half resumed work. The SOFA score on day 3 independently predicted 30-day mortality, highlighting the value of repeated organ function assessment.
