On Friday's Backchat, we looked at the historic New York City mayoral win by 34-year old Zohran Mamdani. He became the first African-born, and the first of South Asian descent to take up the post that oversees the largest city in the United States. His victory was part of a Democratic sweep of several key district elections.
The self-styled socialist-democrat has already announced an all-female transition team as he prepares for New York mayoralty. What challenges will he face in implementing his progressive policies? We found out.
After the break, we learned more about the "Day of Dead", or in Spanish, ''Dia de Muertos'. It's a celebration to honour those who've passed away, and was marked last weekend by Mexico, Latin America and the Philippines.
And finally, we heard from a top astro-physicist in the city about the latest developments regarding the Shenzhou-21, China's crewed spaceflight that recently docked at Tianggong space-station in record time.

On today’s programme, we’re talking about the future of social media under incoming US President Donald Trump.
This comes as Tik Tok services in the US were briefly interrupted following a court ruling mandating its shutdown until it finds a new investors. The interruption — however — was rather short lived, as US users have reportedly regained access to the platform.
President-elect Donald Trump — who will be sworn in less than 24 hours — announced that he will give the app a 90-day reprieve until an agreement is settled on the platform’s future. But this is not the only major social media development happening in the run-up to the return of Trump.
Just last week, Meta announced that it would drop fact checkers in favour of community notes on Facebook and Instagram, in a move some see as a way to regain the hearts and minds of Trump supporters, who previously accused the platform of "censoring" conservative voices.
Some Trump critics — meanwhile — have called on the public to boycott X (formerly Twitter), with some activists accusing the platform — which is owned by Elon Musk — of turning into a conservative "mouthpiece". So are social media platforms at a turning point? We’ll find out.
After 9:50, we speak to a railway researcher on the relaunch of the "Station Rail Voyage" exhibition, featuring the now defunct KTT train which formerly ran from Hung Hom to Guangzhou.
