Helen Czerski ventures beyond the visible spectrum in the final (and best) episode in this vibrant series, showing how electromagnetic radiation is so much broader than the narrow slice of reality we see with our eyes. Before delving into the details of UV, infrared and x-rays, Dr Czerski explores colour subjectivity by trying on a dress that recently divided the internet — to some it appeared blue and black, to others white and gold. It's a perfect fit. It's also a neat analogy of how people can have opposing views but both swear blind that their perspective is correct. The series ends with some amazing imaging techniques that show our bodies in a whole new light.

The documentary tells the story of several families as they attempt to escape oppression in North Korea, revealing a world most of us have never seen. They grew up believing their land was paradise. Now, they risk everything in escaping it. In an unforgettable film, follow them on a treacherous journey to defect from their homeland of North Korea, as the threat of severe punishment and possible execution looms over their passage.
Directed by Madeleine Gavin, the documentary centers around Pastor Seungeun Kim, a South Korean human rights activist and director of the Caleb Mission, which has rescued over 1,000 North Korean defectors since 2000.

We will nvestigate the first skeleton that really looks like us –Turkana Boy– an astonishingly complete specimen of Homo erectus found by the famous Leakey team in Kenya. These early humans are thought to have developed key innovations that helped them thrive, including hunting large prey, the use of fire, and extensive social bonds. The program examines an intriguing theory that long-distance running –our ability to jog– was crucial for the survival of these early hominids. Not only did running help them escape from vicious predators roaming the grasslands, but it also gave them a unique hunting strategy: chasing down prey animals such as deer and antelope to the point of exhaustion. Birth of Humanity also probes how, why, and when humans' uniquely long period of childhood and parenting began.

A bistro is typically defined by its modesty – they are relatively small, affordable and humble. The bistro has become rather ubiquitous these days but despite its many incarnations, at its core, a bistro is a place where every man can eat, and eat well. With Petit Trois, Ludo Lefebvre has brought the spirit of the bistro to Los Angeles.
In this episode, Ludo brings us back to Paris to introduce us to some of the people and places that first inspired him to begin a culinary career.

Astronomers are giving us astonishing news, visual proof of the reality of black holes. Stunning new findings are overturning conventional theories. The most common vision of black holes is that they are monstrous and mysterious bodies swallowing everything around them. However, the latest discoveries are drawing a link between black holes and the existence of life. A startling new picture is emerging. The existence of black holes is what made life on Earth possible.

The centre of our galaxy is home to an invisible monster of unimaginable power – a supermassive black hole named Sagittarius A star, with four million times the mass of the Sun. Recent astronomical breakthroughs have confirmed not only that black holes like Sagittarius A star exist, but that these bizarre invisible objects may be the ultimate galactic protagonists.
Stunning CGI takes us back to witness the fiery origins of our galaxy’s black hole 13.6 billion years ago, when the early universe was home to colossal blue stars, and when they ran out of fuel, they collapsed under their own enormous mass, crushing down into an object so small and so dense it punched a hole in the fabric of the universe. Over billions of years, Sagittarius A star feasted on nearby gas, stars, and through cataclysmic mergers with other black holes. A breakthrough discovery by Nasa’s Fermi gamma-ray telescope has shown that our black hole had the power to sculpt the entire galaxy, creating vast bubbles of gas above and below our galaxy and even protecting stars systems as ours.
In a mind-bending conclusion, Brian Cox reveals how our modern understanding of black holes is challenging our concepts of reality to the breaking point. In trying to understand the fate of objects that fall into Sagittarius A star, scientists have come to a stunning conclusion: space and time, concepts so foundational to how we experience the world around us, are not as fundamental as we once thought.
