For many undocumented migrants in South Africa, the past few weeks have brought uncertainty and fear about what lies ahead.

South Africa is the continent’s most developed economy, attracting citizens from poorer countries seeking work. But it also has a high rate of unemployment – almost one in three are without jobs. Although (officially) foreigners make up some 6% of the population, many more migrants are believed to be in the country without papers.

Protestors have told them they have until the end of June to leave, and some nations have already been repatriating their citizens.

In our conversations, we bring together migrants to share their experiences of rising tensions. We also hear from people who have decided to return and South Africans who want an end to illegal migration.

“For us to fix this country of ours, we have to secure our borders,” Olivier tells host James Reynolds. “People here illegally either they are criminals, or they are suffering in the process or they’re just getting a whole bunch of stuff for free and not contributing.”

Since the outbreak of war involving Iran, Israel and the U.S. in late February 2026, Iranians have been living through months of fear, instability and profound uncertainty. A fragile truce came into effect on April 8, but by May 2026 ceasefire efforts were still under strain, with negotiations continuing and tensions in and around the region far from settled.

In this edition of Heart and Soul, Emily Wither speaks to Iranians inside the country about how war, repression and disillusionment have reshaped their relationship with religion. For some, years of state control in the name of Islam — now intensified by the trauma of recent conflict — have deepened the divide between official religion and personal faith.

Some still pray to God, but in intimate, private ways far removed from state doctrine. Others have drifted away from formal religious belief altogether, finding comfort instead in Persian poetry, music, mysticism and ancient cultural texts such as the Shahnameh. Through anonymous voices from inside Iran, the programme explores a quiet but profound spiritual shift: away from imposed religion, and toward more personal and self-fashioned ways of making meaning.

It is an unlikely migration trend: Westerners swapping their lives in Texas or London for Moscow or Nizhny Novgorod. In 2024, President Vladimir Putin introduced the Russian Shared Values visa, sometimes called the 'anti-woke' visa, offering up to three years of residency to citizens of 47 so-called ‘unfriendly’ countries who say they align with Russia’s traditional spiritual and moral values. Applicants do not need to speak Russian or pass a history test to qualify. Instead, they must reject the social and cultural direction of their home country. We hear the stories of people making this move. What motivates them, and how do their expectations compare with the reality of life in Russia?

The documentary tells the story of scientific hubris through the extraordinary life of one chimp, Sheba. Now 44, she lives in sanctuary at Chimp Haven in Louisiana. Born in a cage, raised in a zoo, she spent twenty-four years in a research laboratory. Her life mirrors our evolving relationship with the animal world.

Sheba is the daughter of Nim, a famous chimp who learned sign language. Like her father, she demonstrated remarkable intelligence, learning to add, subtract, and paint. Her story traces back to a bold 1970s idea: if chimps are so genetically and behaviourally close to humans, could they help us learn about ourselves? Many scientists, like Bob Ingersoll, pursued that question through a series of behavioural and social experiments. Others pursued it through invasive biomedical research.

But the deeper they went, the shakier the premise became. As Bob reflects, much of the research proved not only scientifically flawed, but ethically troubling, often meaningless and cruel. That realisation sparked a shift. By 2016, biomedical research on chimpanzees in the U.S. had come to an end. In the UK and European Union, biomedical research ended a few years earlier.

Through Sheba’s journey, we hear about that turning point.

Featuring interviews with those who knew and worked with her, the documentary also includes zoologist Charlotte Uhlenbroek, who, drawing on years of studying chimps in the wild, guides us inside the world of primate research. The documentary confronts a question that is still unresolved: we have the need to experiment, but do we have the right?
