The Atemoya Custard Apple is a much sought-after fruit grown only in one county in Taiwan. The Taiwanese are justly proud of it. Meanwhile, the Musang King Durian - grown in Malaysia - is also highly prized for its unique flavour as the ‘Hermes of Durians.’ Every year, fruit lovers across the region look out for these treats and snap them up where they can, often paying high prices. In recent years, farmers have seen opportunities to raise their income by selling these niche, super-luxury fruits on the Chinese market, but the strategy comes with big risks too. Koh Ewe from the BBC’s Singapore Bureau has been tracking the fortunes of these two fruits.

With on-location recording of Yasuo on his 763rd dive, this Heart and Soul documentary explores his search as an act of devotion shaped by Japanese ideals of grief, memory, and the power of nature.

Once a quiet hobby for enthusiasts, ant-keeping has exploded into a global, multi-million-dollar business driven by social media and a rising wave of "ant-influencers". Demand for exotic species is fuelling a boom in online trading forums, and a new front in wildlife trafficking.
