    "Treasure-Hunt Stories: A 25-Year Cinematic Journey" exhibition / US tariffs on drones / HKU's cancer mutation detection algorithm / Lingnan University's endangered fish discovery

    On this programme, we hear more about the latest exhibition by the Hong Kong Film Archive as it's celebrating its 25th anniversary.

    We then turn our attention to the United States as Donald Trump's announced tariffs of up to 100 percent on imports of unmanned drones and their components. This comes as Washington concluded that the country was too reliant on foreign sources of drones.
    After the break, a professor from the University of Hong Kong will tell us how he and his team had successfully developed a deep-learning algorithm that will significantly improve the detection of cancer mutations.
    And to wrap up the show, we take a closer look at research conducted by the Lingnan University that's led to the discovery of a critically endangered fish in the city's waters.
