Beijing Summit Recasts U.S.-China Ties as G-2 Parity

At a high-profile Beijing summit, Xi Jinping and Donald Trump portrayed the United States and China as equally dominant powers, reviving the idea of a G-2. The talks yielded trade promises (including China buying Boeing jets and U.S. agricultural products) and discussions on artificial intelligence, but produced no decisive policy breakthroughs on Iran, Taiwan, or security, signaling a focus on optics and multipolar balance over immediate concessions.

Muon g-2 Mystery Reconciled as Standard Model Gains Ground

A long-standing puzzle about the muon's anomalous magnetic moment (g-2) is resolved by a new, ultra-precise lattice QCD calculation that aligns the Standard Model prediction with experimental measurements within half a standard deviation. The result removes the need for a hypothetical fifth force and reinforces quantum field theory as the foundation of particle physics, though it may still leave a narrow window for new physics to appear in future experiments.
