    OpenAI Solves Navier-Stokes Millennium Problem Using AI

    OpenAI has made a significant breakthrough in mathematics by solving the Navier-Stokes problem, one of the seven Millennium Prize Problems. The company's new AI model, significantly more capable than GPT-6 Astra, produced a proof for the existence and smoothness of the Navier-Stokes equations in just 88 hours. The proof, produced by a group of 10,000 agents, was verified using GPT-6 Astra and published in the Lean language. The Navier-Stokes equations describe the motion of fluids and gases, and the problem asked whether these equations break down completely in certain situations. OpenAI's proof claims to have identified such a situation, something that no one could do for over 200 years. This is the second millennium problem to be solved by AI, following the Poincaré conjecture solved by Russian mathematician Grigory Perelman.

    Gaia Spacecraft Discovers Three Dormant Black Holes

    Astronomers using data from the Gaia spacecraft have identified three stellar-mass black holes that were previously undetectable due to their dormant state. These black holes, which do not emit light, were discovered through their gravitational influence on nearby stars. The findings challenge current understanding of stellar evolution, as two of the systems consist of close binary pairs that should not have survived the collapse of the heavier star.

    China Issues Guidelines for AI-Related Disputes

    China's Supreme People’s Court has issued detailed guidelines for handling AI-related disputes. The guidelines address issues such as AI-generated face swaps and voice cloning, liability for harm caused by AI hallucinations, and the protection of intellectual property rights in the AI era. The court also clarifies rules for unauthorized use of AI to create digital replicas of individuals, algorithmic price discrimination, and false information generated by AI.

    BRICS Nations Explore Local Currency Trade, Digital Currencies to Reduce Dollar Dependence

    BRICS nations are discussing and implementing measures to facilitate trade in local currencies and digital currencies to reduce dependence on the US dollar. India, as the current chair, is leading initiatives such as rupee internationalisation, SRVA accounts, and interoperable fast-payment systems. The 18th BRICS Summit in New Delhi will focus on these topics, with India presenting concepts like seamless cross-border digital payments and digital central bank currencies.
