Every second of your life you are under attack. Bacteria, viruses, spores and more living stuff wants to enter your body and use its resources for itself. The immune system is a powerful army of cells that fights like a T-Rex on speed and sacrifices itself for your survival. Without it you would die in no time. This sounds simple but the reality is complex, beautiful and just awesome. An animation of the immune system.

Since the Industrial Revolution, humans have released over 1.5 trillion tonnes of carbon dioxide or CO2 into the earth's atmosphere. In the year 2019 we were still pumping out around 37 billion more. That’s 50% more than the year 2000 and almost three times as much as 50 years ago. And it’s not just CO2. We’re also pumping out growing volumes of other greenhouse gases such as methane and nitrous oxide. Combining all of our greenhouse gases, we’re emitting 51 billion tonnes of carbon dioxide equivalents each year. And emissions keep rising – but they need to get down to 0!

The largest things in the universe are black holes. In contrast to things like planets or stars they have no physical size limit, and can literally grow endlessly. Although in reality specific things need to happen to create different kinds of black holes, from really tiny ones to the largest single things in the universe. So how do black holes grow and how large is the largest of them all?
Never before in human history have we been richer, more advanced or powerful. And yet we feel overwhelmed in the face of rapid climate change. It seems simple on the surface. Greenhouse gases trap energy from the Sun and transfer it to our atmosphere. This leads to warmer winters, harsher summers. Dry places become drier and wet places wetter. Countless ecosystems will die while the rising oceans swallow coasts and the cities we build on them.

Dramatic Sea Rescues Some of the Twentieth Century's most famous examples, with emphasis on how the rescue services have operated in the most appalling conditions. When the "unsinkable" Titanic struck an iceberg on her maiden voyage, she went down long before rescue ships could reach her. Those who survived owed their lives to the brave, self-sacrificing efforts of some of the crew and passengers on board. Shipbuilding, sea communications and rescue capabilities have advanced since then, but as the ill-fated voyages of the Morro Castle, Andrea Doria, Estonia and others show, disaster can strike at any time. And when it does, heroic efforts often mean the difference between survival...and a watery grave. Disasters at sea can be due to war, negligence or more often the force of nature. The twentieth century is littered with examples of sea disasters, from the negligence that sunk the unsinkable Titanic on her maiden voyage, to the tragedies of war and the weather. However, if the cause of the disaster was bad weather, the rescue services then have the most difficult task of responding to the SOS in the most appalling conditions.

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.

In the first episode of an exciting three-part series, Professor Robert Bartlett explores how the Normans developed from a band of marauding Vikings into the formidable warriors who conquered England in 1066. He tells how the Normans established their new province of Normandy -'land of the northmen' - in northern France. They went on to build some of the finest churches in Europe and turned into an unstoppable force of Christian knights and warriors, whose legacy is all around us to this day. Under the leadership of Duke William, the Normans expanded into the neighbouring provinces of northern France. But William's greatest achievement was the conquest of England in 1066. The Battle of Hastings marked the end of the Anglo-Saxon aristocracy and monarchy. The culture and politics of England would now be transformed by the Normans.

The Scorpion King was a mythical Egyptian ruler who predated the pharaohs. Recent developments, such as the excavation of the king's tomb, have revealed surprising new details about early Egyptian civilization. This program details the continuing research into the earliest period of Egyptian history that was inspired originally by discoveries such as the Narmer palette and the Scorpion mace head. The combined efforts of a number of archaeologists have pushed the boundaries of Egyptian civilization back into a period previously considered prehistoric. As a result some of the most fundamental beliefs about Egyptian civilization require a re-think. Is there more behind the mythical and violent leader known simply as the Scorpion King? New evidence suggests that his achievements may have layed the foundations of Egypt. Learn more about the king who likely united ancient Egypt, organized the world's earliest phonetic writing system, and inspired the creation of the pyramids.
