LHAASO Uncovers Formation of Cosmic Ray
Scientists using LHAASO — China's Large High Altitude Air Shower Observatory — found that black holes, devouring material from their companion stars and producing jets, act as powerful particle accelerators and may play a key role in the production of high-energy cosmic rays in the Milky Way.
Chinese Cities Dominate Nature Global Science Ranking
The newly released "Nature Index 2025 Science Cities" supplement shows that the number of Chinese cities in the global top 10 rose from five in 2023 to six in 2024, marking the first time China holds a majority in the rankings.
New Fusion Device Exceeds Highest Plasma Pressures
Zap Energy's new fusion device FuZE-3 has achieved plasmas with electron pressures as high as 830 MPa, or 1.6 GPa total, comparable to the pressures found deep below Earth's crust. The results are the highest pressure performance to date in a sheared-flow-stabilized Z pinch and an important marker on the path to scientific energy gain.
AI Creates 100-bln-star Milky Way Tracking Model
Combining deep learning with high-resolution physics, researchers from Japan and Spain created the first Milky Way model that can track more than 100 billion individual stars across 10,000 years of evolution. The simulation is hundreds of times faster than current methods.
