Vases crafted thousands of years ago, temples built by past civilisations, natural parks with stunning waterfalls. These are all tangible things, there is a physical trace of them and many times they are protected and valued.

But what about festivals, recipes or dances and skills that are unique to a certain part of the world? These cannot be stored, really. However they are passed on, become part of many people’s identities and are known as intangible cultural heritage.

UNESCO, the United Nations agency that focuses on culture and education has released its yearly list recognising these practices. But what does it actually mean to be included and why is it celebrated? We hear from Matthieu Guevel, Chief of Communications at UNESCO.

Plus we talk to three people whose cultural practices have been added to the list this year: Paola Maggiulli a British-Italian cook, Lika Kat, a content creator from Kyrgyzstan and Zahra Hankir, a Lebanese author and journalist.

Stray Kids or BlackPink? Spice Girls or Westlife? Music executives - like Simon Cowell - have been creating girl bands and boy bands for decades. And he’s about to launch a brand new competition on Netflix to find “The Next Act”. When we talk about these groups, we generally mean good-looking young women or men who’ve been brought together, and who don’t tend to write their own songs or play their own instruments. Their fans are stereotyped as being teenage girls and their mums.

Is there any truth to the belief that girl bands make better music because they are held to higher standards? The BBC’s music correspondent Mark Savage explains how pop bands have evolved over the decades. We look at the different pressures and stereotyping that girl and boy bands face and we hear from some of our BBC friends - do they prefer girl bands or boy bands and why?

More than half a million people have been forced to leave their homes in Cambodia and Thailand. This follows rising conflict over the two countries’ shared border. Now, this is not a new dispute. In fact it’s been going on for decades. But this year things have gotten worse. A ceasefire was negotiated by US president Donald Trump in October. But it hasn’t held. Trump now says he will ‘make a phone call’ to stop the fighting.

BBC reporter Panisa Aemocha, in Bangkok, chats us through the humanitarian needs of hundreds of thousands of evacuees. We also from the BBC’s South East Asia correspondent Jonathan Head who’s at an evacuation centre, and from two young people who have fled their houses.
