    HK ranking third in Global AI Competitiveness Index / HKUST's AI weather prediction model / 160,000-year-old stone tools discovered in Henan

    On Tuesday’s programme, we explored Hong Kong’s strong performance in AI fluency, after the city secured a top ranking on this year’s Global AI Competitiveness Index. The SAR claimed the number-three spot in the city-hub rankings, which evaluated 20 countries and 15 leading financial centres on AI capability and maturity, only behind New York and London.
    After the break, we continued with tech and learned about the world’s first AI Deep Diffusion Model for Satellite Data, developed by the Hong Kong University of Science and Technology (HKUST). This innovative model can predict extreme convective storms like including thunderstorms and severe rainstorms up to four hours in advance.
    To wrap up, a biological anthropologist shared insights from a new study suggesting that China may have led a Stone Age technological revolution as early as 160,000 years ago. The research highlights sophisticated stone tools crafted for cutting, piercing, and sawing as evidence of advanced composite  technologies in East Asia far earlier than previously recognised.

    主持人:Azam Khan and Rainbow Leung

    On Thursday's programme, we looked at 2026's burgeoning Hong Kong IPO market, which has seen multiple mainland tech firms making strong debuts in the past weeks.


    After the break, we turned our attention to the United Kingdom, where politician Nigel Farage's right-wing Reform UK is seemingly gaining momentum, after a former high-level government minister defected to his party.


    And finally, the head of a space project at the Hong Kong University of Science and Technology told us about the SAR's role in developing a mutifunctional robot that will help the nation's future lunar missions.
