Chinese President Xi Jinping advocated for open-source AI and international cooperation at the World Artificial Intelligence Conference in Shanghai, contrasting with America's protectionist AI policies.

China is establishing the World Artificial Intelligence Cooperation Organization with 29 member nations, including Brazil and Russia, aiming to guide global AI development under Chinese principles. Xi pledged to provide 5,000 AI training opportunities to developing countries over the next five years and to develop international AI application cooperation centers across the Global South.

However, reports suggest that Chinese officials have discussed limiting overseas access to open-source and proprietary models with domestic AI labs, raising questions about the inclusivity of China's "open cooperation" vision, especially concerning the United States. Furthermore, Xi called for stronger AI safety and regulation, emphasizing the need for laws, technological monitoring, and emergency response systems to prevent misuse and ensure AI remains under human control.

Apple briefly surpassed Nvidia to become the world's most valuable company, despite criticisms of its lagging AI efforts and delays in enhancing Siri's AI capabilities. Apple's market valuation reached $4.89 trillion, narrowly exceeding Nvidia's $4.85 trillion.

While Nvidia has been a symbol of success in the AI hype era, achieving a $5 trillion valuation, investor concerns are growing about its revenue growth potentially peaking due to limited returns from massive AI investments by hyperscalers like Microsoft.

Analysts suggest that Apple's strategy of keeping AI capital expenditure within a reasonable range and monetizing AI through services, ecosystem lock-in, and hardware upgrades is a smart move. The debut of Chinese AI startup Moonshot's 2.8 trillion-parameter open-weight model, Kimi K3, which showed high performance against American counterparts, may have also contributed to the shift in market valuation, impacting Nvidia.

Researchers from Fudan University and the Chinese Academy of Sciences have developed a revolutionary zinc-based flow battery that could transform the future of renewable energy storage. This innovative battery achieved over 5,000 hours of continuous operation and demonstrated an impressive coulombic efficiency of 99.94%.

To overcome the degradation issues of traditional zinc battery electrodes, the researchers adopted a novel approach, utilizing zinc not as a solid electrode but as a fluid suspension of tiny zinc particles dispersed in a conductive medium. This design allows zinc to act as a dynamic energy carrier, separating storage capacity from power delivery, making it particularly suitable for large-scale grid applications.

The technology boasts excellent scalability and extended lifespan, positioning it as a crucial component for enhancing stable renewable energy supply and reducing reliance on fossil fuels.
