New Scientist published "AI's solution to 87-year-old riddle takes mathematicians by surprise," providing the first external mainstream science-media corroboration of the Jacobian conjecture counterexample discovered by Claude Fable 5 on July 19. QMUL mathematician Abhishek Saha told New Scientist this is "probably the biggest conjecture that AI has significantly helped to prove or disprove" and confirmed many mathematicians have already independently verified the counterexample. Wikipedia now cites New Scientist as the independent reliable source while keeping the Claude Fable 5 attribution intact. The paper received 593 points on Hacker News with zero mathematics-based objections, and Kimi K3's independent verification using SymPy shows determinant = -2 with three distinct points mapping to the same image — definitive disproof of the 87-year-old Keller 1939 conjecture.
