The Chinese Radio Telescope Array for Interplanetary Scintillation Monitoring
Space WeatherSolar flares, coronal mass ejections (CMEs) and enegertic particles, etc., are the driving sources that may cause catastrophic space weathers. It is desirable to obtain information of solar eruptions like flares and CMEs, etc., propagating from the Sun ...

A semi-empirical approach to simulating the Dst index in global MHD models of Earth’s magnetosphere
Earth and Planetary PhysicsThe Dst index has been commonly used to measure the geomagnetic effectiveness of magnetic storm events for several decades. Based on Burton’s empirical Dst model and the global magneto-hydrodynamic (MHD) simulation of Earth’s magnetosphere, here we ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
