Nolan gets reaction from DUP leader Gavin Robinson and Alliance MLA Nuala McAllister

Misha Glenny and guests discuss the exchange of cultures and biology across the Atlantic and Pacific after 1492. That was when Columbus reached the Bahamas, a time when Europe had no potatoes, tomatoes, sunflowers or, arguably, syphilis in its most virulent form; the Americas had no cattle, bananas, sugar cane or smallpox. The lists of what was then exchanged are long and as these flora, fauna and diseases moved between continents, their impact ranged from transformation to devastation. In parts of the Americas, European viruses helped kill over 90 percent of the population. In parts of Europe, Africa and Asia populations boomed on the new American foods. Sheep from Europe grazed fertile land into deserts in some parts of the Americas, while the lowered populations in others led to local reforestation which, arguably, is linked to a particularly cold period in the Little Ice Age.

In Our Time is a BBC Studios production

Spanning history, religion, culture, science and philosophy, In Our Time from BBC Radio 4 is essential listening for the intellectually curious. In each episode, host Misha Glenny and expert guests explore the characters, events and discoveries that have shaped our world.

A jury in California has concluded that Meta and Google intentionally built addictive social media platforms, in a case brought by a 20-year-old woman who said her compulsive use of social media as a child led to mental health problems. The woman, known as Kaley, has been awarded $6m in damages. The outcome of this trial is likely to have implications for hundreds of similar cases now winding their way through US courts. Parents who say their children were also harmed by social media algorithms celebrated the result outside the court. Meta, which owns Instagram, Facebook and WhatsApp, alongside Google, the owner of YouTube, have both said they will appeal.

Also: President Trump has claimed Iran is ''afraid'' to admit it is negotiating with the US, as Tehran continues to deny reports of dialogue with Washington. The boss of AirCanada is facing calls to resign, after he released a condolence message for the recent deaths of two pilots in English, but not in French. More than 350 years after the death of the legendary French musketeer d'Artagnan, his remains may have been found under the floor of a Dutch church. And scientists now believe dogs became man's best friend much earlier than previously thought.

Benjamin Netanyahu is Israel’s longest serving prime minister. He was born in Tel Aviv in 1949, the year after the State of Israel was founded. One of three brothers, Netanyahu spent much of his early years in the United States pursuing his education. But following his older brother’s death, Netanyahu found himself drawn into a career in the public eye. Using his military experience to advise on security matters, in 1984 Netanyahu became Israel’s Ambassador to the UN and established himself as a champion of Israel on the international stage. He returned to Israel and entered the world of politics; in 1993, he became the leader of the Likud party, and was elected prime minister in 1996, a position he has held for much of the following decades. Mark Coles profiles the longest-serving Israeli prime minister.

A Los Angeles jury has handed down an unprecedented win for a young woman who sued Meta and YouTube over her childhood addiction to social media. We hear the latest.

Since the war in the Middle East erupted, attention has focused on oil and gas flows through the Strait of Hormuz. However, the Gulf is also a major producer of aluminium and helium. We look at how disruption has spread into other commodities.

And it’s not just commodities and supply chains feeling the pressure. Airlines are watching oil prices closely, because fuel is one of their biggest costs. We hear from the boss of AirAsia Group, the Malaysian budget airline, on what might happen, should oil prices remain high.

A California jury has found the social media giants Meta and Google liable for harming a young user's mental health by deliberately making their products addictive. We hear from a former Facebook employee.

Also on the programme: amid talk of peace, many Iranians continue to flee their country. We hear from one who took part in January's bloody anti-regime protests.

And: the BBC has a new director general. Will the appointment from the world of tech help the corporation navigate a changing media landscape?

A 20 year-old Californian woman has been awarded a total of $6 million in damages after taking Meta and Google to court, accusing the tech giants of making her addicted to social media. The jury found the firms liable for negligence, contributing to her mental health problems.

Also in the programme: Iran's foreign minister has said officials are reviewing US proposals on ending the war, but that Tehran has no intention of holding talks with the United States; and Sarah Mullally has been officially installed as the first woman to lead the Anglican Communion.

Esme is celebrating on Lady Day, and George has something to say.

Iran's state broadcaster says that Tehran has responded "negatively" to a US peace plan. A senior, unnamed official said Iran would end the war when it decided to do so - and when "its own conditions are met". The details of the 15-point plan were never made public, but it's reported to have demanded major concessions from Tehran. Also, after declaring an energy emergency, the Philippines said it was seeking new sources of oil from sanctioned countries, including Russia. The CEO of investment firm Blackrock said that if the war led to long-term high oil prices, there would be a global recession. We also hear from some of the survivors of the convicted sex offender Jeffrey Epstein, the impact of a smartphone ban in Dutch schools, and how an Australian dog that was used to rescue koalas is getting a well-earned retirement.

The Asian Development Bank's Chief Economist Albert Park tells us that the conflict in the Middle East could prove 'traumatic', knocking as much as 1.3% of Asian GDP growth, depending on how long it goes on for. He believes that the countries most vulnerable include Sri Lanka, Maldives, Laos, Bangladesh and Pakistan. Meanwhile the price of jet fuel has more than doubled since the start of the war with Iran, with numerous major airlines raising their prices. Jetstar New Zealand cancelled some domestic services and flights between Australia and New Zealand. Vietnam Airlines also scrapped almost a two dozen domestic flights a week. And why shares in the Chinese toy-maker Pop Mart – who make Labubu Dolls – have tumbled more than twenty percent…their biggest drop in nearly a year.
