In March this year, 25-year-old Noelia Castillo died by lethal injection. Her father had fought in the courts for nearly two years to stop her euthanasia. Noelia applied for assisted dying because she had been left paraplegic, debilitated and in pain after a suicide attempt. Her case dominated Spain’s headlines for months. And the debate about who has the right to challenge an adult’s decision to have euthanasia has not gone away. In May, the Supreme Court ruled that those with, ‘a particularly close connection’ to the person wanting to die may have the right to contest an application for euthanasia.

But there are families unsettled by the Supreme Court’s ruling. When Puri and Salvador’s daughter, Ana, chose assisted dying at the age of 28 they didn’t think about intervening in her decision,…because she was an adult, because she was independent,” says Puri. Ana had been born with Spina Bifida and became increasingly unwell with neuropathic pain that is difficult to treat.

Something that gave Puri and Salvador immense comfort after they lost their daughter was the knowledge that Ana’s organs were donated (with Ana’s permission) to keep others alive. And it’s the issue of organ donation that is helping to keep the euthanasia story in the news in Spain. Noelia’s mother, Yolanda Ramos, claims her daughter was under pressure to commit to donating her organs. And the anti-euthanasia Foundation of Christian Lawyers in Spain (Fundacion Espanola de Abogados Cristianos) that has represented both of Noelia’s parents is advocating a ban on organ donation in euthanasia cases. Why does this matter?

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.

A statue of Saint Olga is a much-loved figure in Central Kyiv, Ukraine. So much so, that when Russia invaded Ukraine, the statue was given a flak jacket with the words “she needs armour” written on it. Saint Olga of Kyiv is celebrated by Ukrainians and Russians alike. She’s a saint in both the Catholic and Orthodox churches and her saint’s day is celebrated on 11th July. BBC Ukrainian’s Irena Taranyuk explores her sometimes violent history.

In a summer of world class sporting events, tennis players have been battling it out at Wimbledon - one of the four major Grand Slam tournaments. One of the big stories has been the success of British wildcard entry Arthur Fery who, before Wimbledon, was ranked outside the top 100. His success has come with a big jump in prize money - essential to pay for the international travel, accommodation and coaches required to keep climbing the rankings. For those lower down the ranks, life on the professional circuit can be tough both emotionally and financially. Hamish Stewart, from Scotland, is currently ranked 300 and is all too aware of the personal demands of the job. "I've just missed an ex-college teammate of mine's wedding," says Stewart. He is joined by Jamie Loeb from the US, who is currently ranked outside the top 1,000. She had a career high of 132 and played in the US Open before injury and personal circumstances stalled her rise. We also hear from three coaches - Viktoria Belinsky, Noelle van Lottum and Michael Logarzo - who give us an insight into their jobs, the sport and its parallels with 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.
