When you listen to a radio programme, watch an animated film, or even receive a phone call, it’s unlikely you’ll question whether the words you’re hearing are coming from the mouth of a human being. But all that could be about to change thanks to the rise of ‘voice cloning’. Elaine Moore is a tech columnist at the Financial Times and she’s interested in the ramifications of this new technology. Thanks to artificial intelligence, cloning a human voice can be achieved with just a few minutes of recorded audio. As the technology becomes more sophisticated and its use more widespread, how will this affect our society, our politics and our personal interactions? And is it time we were able to control what happens to our own voice both now and when we die? With contributions from: Carlton Daniel, lawyer at Squire Patton Boggs. Tom Lee, co-founder of LOVO.

This summer's hasty and poorly executed withdrawal of US forces from Afghanistan caused shock and profound unease among Washington's allies, just as they hoped the unilateralism of the Trump era had been left behind. But anxiety about America's position on defence only intensified with the unveiling in September of AUKUS - a trilateral security pact involving Australia, the US and UK covering the Indo-Pacific region. The exclusion of France from that deal not only enraged Paris but also further alarmed European allies about American intentions. So what next? Can the Biden administration be trusted to uphold the security guarantee which underpins NATO? Or, as France's President Emmanuel Macron argues, do these and other actions by the United States show that the 70 year-old Alliance is effectively "brain dead" and that Europe has to set about achieving "strategic autonomy" without depending on Washington's whims? In a lively forum with key players and thinkers about European security from both sides of the Atlantic, Edward Stourton considers what should happen now on European defence and whether seemingly divergent views about it can be reconciled. Those taking part: Professor Malcolm Chalmers, Deputy Director of the Royal United Services Institute in London; Nathalie Loiseau, MEP, former French Minister of European Affairs and Chair of the European Parliament's Sub-committee on Security and Defence; Dr Constanze Stelzenmüller, expert on Germany and trans-Atlantic Relations in the Center on the United States and Europe at the Brookings Institution in Washington, D.C.; and Linas Linkevicius, former Foreign and Defence Minister of Lithuania.

What keeps a nation together? For political scientist Benedict Anderson, it was the idea of the 'imagined community'. Although people from different backgrounds in a country might not know one another, they could imagine themselves as part of the same larger story. Peter Pomerantsev looks at how we can survive as a society when the idea of the 'imagined community' is under strain. Is it too late to find any commonality? Or are there other ways of imagining the future of the nation? Producer Ant Adeane Editor Jasper Corbett

In June 2020 the statue of slaver trader Edward Colston was toppled and thrown into the harbour in Bristol – one of the most visible moments of the Black Lives Matter movement in the UK. The statue now lies on its side in a museum, a testament to the dramatic re-evaluation of Bristol’s painful history at the centre of the transatlantic slave trade. Over the last year schools and buildings bearing Colston's name have been renamed. Colston has been cancelled. But what about the system of wealth, power and race that he represented? Bristol journalist Neil Maggs speaks to the people in Bristol dealing with Colston’s legacy. Current members of the Society of Merchant Venturers, a powerful charitable organisation which promoted Colston’s reputation as a philanthropist, have suddenly been thrust into the spotlight. School leaders are rolling out unconscious bias training. Elsewhere community leaders and politicians are navigating the potential for a backlash against terms such as white privilege as the national conversation on race continues.

In an age of social media ’cancel culture’ might be defined as an orchestrated campaign which seeks to silence or end the careers of people whose thoughts or opinions deviate from a new set of political norms. So if this threat exists for anyone expressing an opinion online in 2021, what’s it like for scientists working in academia and publishing findings which might be deemed controversial? In this edition of Analysis, Michael Muthukrishna, Associate Professor of Economic Psychology at the London School of Economics, assesses the impact of modern social justice movements on scientific research and development. Speaking to a range of experts, some who have found themselves in the firing line of current public discourse, and others who question the severity of this phenomenon and its political motives, Michael asks: if fear of personal or professional harm is strengthening conformism or eviscerating robust intellectual debate, can open-mindedness on controversial issues really exist in the scientific community? Or is rigorous public assessment of scientific findings helping to achieve better, more equitable and socially just outcomes?
