    New LegCo term priorities / Indian cybersecurity app controversy / Humanoid robot development

    On Tuesday's programme, we talked to several lawmakers-elect on what their vision and priorities are for the upcoming term. They will be sworn in along with their fellow legislators on January 1st, at a ceremony administered by Chief Executive John Lee.
    After the break, we spoke to our tech correspondent about the Indian government's cybersecurity app - Sanchar Saathi. New Delhi initially ordered phonemakers in the country to install it but eventually revoked the order and made it voluntary, following backlash from tech companies and the opposition party.
    And lastly, we discussed with a lead researcher from Polytechnic University who helped create a new cutting-edge robotic system that will change the entire manufacturing landscape.

    Climate change and extreme weather / Suspected food tampering cases / HKU's GBA healthcare survey

    Presenters:Brian Wong and Rainbow Leung

    On Friday's Backchat, we started off by talking about the recent Black Rainstorm Warnings. 
    Even though Hong Kong was spared from the brunt of Typhoon Podul, its associated thunder and rain storms have lashed the city. At the same time, a number of countries in Europe are still putting out wildfires that are being fanned by a heatwave. We took a closer look at climate change's global impact. 
    After the break, we talked to a psychologist to look at why people would tamper with food and how this sort of behaviour can be prevented. 
    And to end the show, we spoke with an urban planner about why more people have been travelling north to the Greater Bay Area for their healthcare needs. 

    9:05am-9:30am: Climate change and extreme weather
    Speaker: 
    Benjamin Horton, Dean of the School of Energy and Environment; Chair Professor of Earth Science at City University of Hong Kong

    Martin Williams, Hong Kong-based writer, conservationist (PhD) and owner of DocMartin Williams, which provides wildlife tours and documents changes in weather patterns
