In the aftermath of Hiroshima, a group of scientists vowed never to turn knowledge into weapons again, and from that promise, CERN was born. Deep underground, researchers from nations in conflict have worked side by side for decades, driven by curiosity and shared wonder. For 70 years, CERN has stood as an act of hope, a place where collaboration transcends borders, even as the world above grows more divided. Blending poetry, music and rare archival footage of nuclear physicist Robert Oppenheimer with remarkable access to the Large Hadron Collider, the film explores how science, politics and culture collide.

Behind the billion-pound success of OnlyFans lies a hidden ecosystem of exploitation. A BBC Current Affairs investigation uncovers allegations of exploitation, coercion and violence committed by some of the hundreds of agents who manage many of the platform's creators as well as the potential for modern slavery. Through survivor testimony, undercover access to a managers' chat forum and expert legal analysis, the film exposes an industry where young women are trapped, threatened and profited from - raising urgent questions about accountability at the heart of one of Britain's most lucrative tech companies.

Liz Bonnin presents a controversial and provocative episode of Horizon, investigating how new scientific research is raising hard questions about zoos - the film explores how and why zoos keep animals, and whether they need to change to keep up with modern science, or ultimately be consigned to history. Should zoos cull their animals to manage populations? Liz travels to Copenhagen Zoo, who killed a giraffe and fed it to the lions, to witness their culling process first hand. They think it is a natural part of zoo keeping that is often swept under the carpet. Should some animals never be kept in captivity? In a world exclusive, Liz visits SeaWorld in Florida and asks if captivity drove one of their orcas to kill his trainer. But could zoos be the answer to conserving endangered species? Liz examines their record, from helping breed pandas for the wild to efforts to save the rhinos. She meets one of the last surviving northern white rhinos and discovers the future of this species now lies in a multimillion-dollar programme to engineer them for stem cells. Veteran conservation scientist Dr Sarah Bexell tells Liz the science of captive breeding is giving humanity false hope.
In this episode, Chris Packham tells the miraculous story of how plant life turned Earth from a barren rock into a vibrant green world. A four billion year saga of extraordinary highs and lows that almost wiped out all life on the planet. Four billion years ago Earth was predominantly a water world, lacking land masses, with plant life’s early ancestors trapped on the seabed. Everything changed when a giant asteroid bombardment smashed into the young planet’s crust triggering plate tectonics - Earth’s extraordinary land building force. As opportunities on land grew, plants faced an epic struggle to establish themselves in a world dominated by giant eight metre fungi, overcoming death and dehydration and eventually creating the life-giving substance that would allow them to prosper: soil. But just as they seemed set to triumph, evolving into the amazing biological machines that are trees, they became the victims of their own success. Giant swamp forests sprang up, locking up so much carbon dioxide, that global temperatures plummeted sending Earth into one of its most terrifying chapters yet.

Dr Hannah Fry explores the limits of our control, from dangerous miscalculations to creating and spotting fake videos, and questions how far we should be going with our mathematical skills. A gravity-defying BMX stunt kick-starts the debate around trusting the numbers, and launches us into an investigation of just how sure we can be about anything in our messy world. Together with maths comedian Matt Parker, Hannah uses flaming balloons and gigantic slices of melting cheese to get to the bottom of the guesswork used in real world calculations. A visiting drone zips through the corridors of the historic Royal Institution building, introducing the mother of all drones, a human-sized machine that delivers urgent parcels, and we welcome the team designing driverless helicopters and buying up London rooftops to prepare for the future. But these physical challenges are just the beginning of the debate on handing control over to machines. Hannah explores whether human jurors or robots make fairer decisions, and welcomes Atima Lui, who is on a mission to design the most unbiased facial detection software in the world, which will say goodbye to the 'fast track for white people' at automatic passport gates. Hannah dives into the issues around privacy in our modern world, with Glow Up make-up star Tiffany Hunt making a member of the audience invisible to CCTV, while Hannah explores the truth behind cookies and anonymity online. Finally, she delves into the world of fake news, to separate the truth from the lies. Leading deep fake creators team up with the Christmas Lectures to create a television first – a custom-made deep fake video of a child in the audience, highlighting our ability to use maths to warp reality however we please. Hannah ultimately explores who the real winners are, in an escalating arms race of mathematical tricks.
