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.

As France fell to the German armies in May 1940, 300,000 Allied troops were trapped on the beaches of Dunkirk. Their annihilation seemed certain - a disaster that could have led to Britain's surrender. But then, in a last-minute rescue dramatized in Christopher Nolan's recent film, Royal Navy ships and a flotilla of tiny civilian boats evacuated hundreds of thousands of soldiers to safety across the Channel - the legendary "miracle of Dunkirk." Now, NOVA follows a team of archaeologists, historians, and divers as they recover the remains of ships, planes, and personal effects lost during the epic operation. With access to previously classified files recently released by the UK government, they also uncover the truth behind the myths of Dunkirk - notably, a claim that the Royal Air Force failed to protect the stranded men from the Luftwaffe's constant bombing of the beaches. Featuring an exclusive excavation of a newly-found Spitfire wreck, NOVA debunks the myth and highlights the essential role that the RAF's iconic fighter played in reversing the desperate stakes that played out in the air above the beleaguered men.

From a bee’s hexagonal honeycomb to the elliptical paths of planets, symmetry has long been recognized as a vital quality of nature. Einstein saw symmetry hidden in the fabric of space and time. The brilliant Emmy Noether proved that symmetry is the mathematical flower of deeply rooted physical law. And today’s theorists are pursuing an even more exotic symmetry that, mathematically speaking, could be nature’s final fundamental symmetry: supersymmetry.
