AI agents help solve decades-old plasma physics problem for fusion research

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.
