Most people hear "Romania" and immediately picture Dracula, the gothic myths of Bran Castle, or the grey, concrete remnants of the communist era. But the reality of this nation in Eastern Europe is far more complex, untamed, and beautiful.

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.

Particle physicist Dr Brian Cox wants to know why the Universe is built the way it is. He believes the answers lie in the force of gravity. But Newton thought gravity was powered by God, and even Einstein failed to completely solve it. Heading out with his film crew on a road trip across the USA, Brian fires lasers at the moon in Texas, goes mad in the desert in Arizona, encounters the bending of space and time at a maximum security military base, tries to detect ripples in our reality in the swamps of Louisiana and searches for hidden dimensions just outside Chicago.
It's called the speed limit of the universe. Einstein blew all of our minds when he worked out the Theory of Relativity, and showed that space and time were malleable substances. He also theorized that we as humans can never travel faster than the speed of light, which leaves the stars and other galaxies almost impossibly out of our reach. But the dreams of Star Wars and Star Trek are not dead. In fact, there could be ways to travel faster than the speed of light - and some of them are already being tested in labs around the world.

How we finally came to understand the science of electricity.
After four centuries of occupation and leadership, the Romans left Britain in 410 AD and the island’s fate was left hanging in the balance. History teaches that in the 5th century, the country descended into a tumultuous and violent period knows as the Dark Ages, leaving the nation vulnerable to invading Angle and Saxon hordes from northern Europe. With a nation divided, great leader known as King Arthur emerged, uniting the lawless lands to fight off invaders – or at least that’s what the fragmentary historical texts suggest. The truth is, no one really knows what happened, and this pivotal moment in history has been shrouded in mystery – until now. Professor Alice Roberts and a team of experts use new archaeological discoveries to decode Dark Ages myths and piece together a very different story of this turning point in Britain’s history that might also explain the legend of King Arthur.

First transmitted in 1965. David Attenborough continues his journey along the Zambezi River. This episode begins at Victoria Falls, the largest waterfall in the world. At the foot of the falls, with its moist climate, a wealth of plants and animals can be found, such as hyraxes. To coax the hyraxes out of hiding, David Attenborough illustrates why taking a dog whistle with you while on an African adventure is a very good idea indeed. Other highlights encountered on the way include an estivating lungfish and a herd of elephants washing and dust bathing at a water hole.Further along his journey David Attenborough explores a Portuguese fortress at Tete, believed to have been built over 400 years ago, and assesses the impact of the then newly constructed Kariba Dam, one of the largest dams in the world, on the displaced Tonga people and surrounding countryside.
As almost all animal inhabitants of Antarctica are forced to migrate north, the sea underneath the frozen ice still provides a home to many specially adapted fish whose cells are protected from freezing through an "antifreeze" liquid. Many of them feed on the faeces of other animals. The most notable larger animal that does not migrate north is perhaps the Weddell Seal, which can be found as close as 1300 kilometres to the pole. Groups of seals tear holes into the ice to dive for food and come up to breathe. The females come back to the ice to give birth.
