In coastal Japan, Yasuo Takamatsu has spent nearly 15 years diving for the remains of his wife, Yuko, who was swept away in the 2011 tsunami. 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. A profound story of love and loss, we reveal how one man’s repeated dives became a ritual of remembrance in a land where disaster is part of life.

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. We go to Kenya, where law enforcement has made global headlines arresting gangs as they try to smuggle thousands of prized mated queens out of the country.

As the United States approaches its 250th anniversary, all this week The Global Story is exploring the surprising and often hidden ways the US has shaped the modern world.

For decades in the US, “Made in China” signified a product that was cheap, poorly made, and, in some cases, produced through exploitative labour. But today, the label signifies something quite different in many American minds - state-of-the-art tech and luxury goods that even rival America, for arguably the first time in US history.

Often overlooked is the fact that China’s ascendance as an economic superpower was far from inevitable. Today we speak to historian Elizabeth Ingleson to trace the evolution of the Made in China brand and to explore what responsibility the United States had for awakening its own economic rival.

The Global Story tells in-depth stories from where the world and America meet. For more episodes, just search 'The Global Story' wherever you get your BBC Podcasts.

Worried about a ballooning population, the Chinese government introduced its infamous one-child policy in 1980. At the time it seemed urgent to find ways to reduce the number of babies being born. China today has the opposite problem - too few births. Since the one-child policy was scrapped 10 years ago, there have been increasingly desperate attempts to encourage couples to have more children. But nothing has worked. China’s population has already started to fall. That process will gather pace over the coming decades. The population is on track to halve by the end of the century. Micky Bristow, who has reported on China over more than 20 years, looks at why this is happening, and what the consequences could be.
