TLDR

In fusion research, a Google DeepMind researcher says the team found further counterexamples to Grad's conjecture, described as a 60-year-old plasma physics mystery. The researcher says Gemini 4 Argon also helped discover analytical solutions for stellarator magnetic fields that could improve design-code verification. A separate post quotes the authors as saying they independently checked every derivation.

Pushmeet Kohli@pushmeetIn nuclear fusion, we found further counterexamples to Grad's conjecture, until recently a 60-year-old mystery in plasma physics. Argon helped discover new analytical solutions for stellarator 3D magnetic fields, helping improve code verification for stellarator design. Read more in @opalissan post:23h
Dr Singularity@Dr_Singularitywow AI will solve fusion Huge breakthrough (thanks to Google A ) for fusion Google’s Gemini 4 agents helped crack an open problem in plasma physics, proposing new exact solutions for 3D magnetic plasma configurations, with promising candidates appearing within hours. The AI also wrote verification code, and researchers independently rederived and checked every derivation "Gemini 4 Argon was also used to draft parts of the manuscript and write symbolic and numerical verification code. The authors chose the problem, steered the agents, and ran several rounds of adversarial review. Every derivation was independently re-derived and checked symbolically by the authors. The authors refined the interpretation and rewrote the manuscript, and take full responsibility for its content."2h
