The Messenger explores our deep-seated connection to birds and warns that the uncertain fate of songbirds might mirror our own. Moving from the northern reaches of the Boreal Forest to the base of Mount Ararat in Turkey to the streets of New York, The Messenger brings us face-to-face with a remarkable variety of human-made perils that have devastated thrushes, warblers, orioles, tanagers, grosbeaks and many other airborne music-makers. In ancient times humans looked to the flight and songs of birds to protect the future. Today once again, birds have something to tell us.

In 1966, drought and an exploding population confronted India with the imminent threat of a severe famine that many scientists and intellectuals feared was a harbinger of global catastrophes to come, as the world's population outstripped its ability to produce food. India turned to Norman Borlaug, an unassuming plant breeder from Iowa whose combination of scientific knowledge and raw determination had made him a legend among a small handful of fellow specialists. The Man Who Tried to Feed the World recounts the story of the man who would not only solve India's famine problem, but would go on to lead a "Green Revolution" of worldwide agriculture programs, saving countless lives. He was awarded the 1970 Nobel Peace Prize for his work but spent the rest of his life watching his methods and achievements come under increasing fire.

Horizon investigates a new era of Alzheimer's research, which is bringing hope to millions of sufferers across the world. New scanning and gene technology is allowing scientists to identify the disease at its earliest stages, often 15 years before symptoms appear and the brain cells are destroyed. A series of new drugs trials in Colombia, the USA and Europe are showing startling success in reducing beta amyloid, the protein which is a hallmark of the disease. It is also becoming clear that changes in lifestyle can prevent the development of the disease. A new system inside the brain has been discovered which clears amyloid when we are in deep sleep, but allows it to accumulate if we don't sleep well. The programme reveals that for sufferers in the early stages of the disease, brain connections, or synapses, can be strengthened and even replaced by absorbing enough of the right nutrients. A UK-wide trail helps sufferers in the early stages to concentrate on improving everyday tasks, and in the process not only make their lives easier, but helps to reactivate the planning and organisational parts of the brain. In an ageing world, where the biggest risk of developing Alzheimer's is old age, the scientific breakthroughs in Alzheimer's disease are bringing hope where once there was despair.
Horizon looks at the issues that will change the way we live our lives in the future. Rather than relying on the minds of science fiction writers, mathematician Hannah Fry delves into the data we have today to provide an evidence-based vision of tomorrow. With the help of the BBC's science experts - and a few surprise guests - Hannah investigates the questions the British public want answered about the future. Hannah tries to discover whether we could ever live forever or if there will ever be a cure for cancer. She finds out how research into the human brain may one day help with mental health, and if it is possible to ever ditch fossil fuels. Hannah and her guests also discover the future of transport - and when, if ever, we really will see flying cars. She discovers whether a robot will take your job or if, as some believe, we will all one day actually become cyborgs. The programme predicts what the weather will be like and discovers if we are on the verge of another mass extinction. Hannah's tenth prediction is something she - and Horizon - are confident will definitely happen, and that is to expect the unexpected!

Black holes are the most enigmatic and exotic objects in the universe. They’re also the most powerful; with gravity so strong it can trap light. And they’re destructive, swallowing entire planets, even giant stars. Anything that falls into them vanishes…gone forever. Now, astrophysicists are realizing that black holes may be essential to how our universe evolved—their influence possibly leading to life on Earth and, ultimately, us. In this two-hour special, astrophysicist and author Janna Levin takes viewers on a journey to the frontiers of black hole science. Along the way, we meet leading astronomers and physicists on the verge of finding new answers to provocative questions about these shadowy monsters: Where do they come from? What’s inside? What happens if you fall into one? And what can they tell us about the nature of space, time, and gravity?

The car has shrunk the world, increased personal freedom and in so many ways expanded our horizons, but there is a flipside. Fumes from car exhausts have helped to destroy our environment, poisoned the air we breathe and killed us in far more straightforward ways. But all that is going to change. Horizon enters a world where cars can drive themselves, a world where we are simply passengers, ferried about by wholesome green compassionate technology which will never ever go wrong. And it is almost here. Horizon explores the artificial intelligence required to replace human drivers for cars themselves, peers into the future driverless world and discovers that, despite the glossy driverless PR (and assuming that they really can be made to work reliably), the reality is that it might not be all good news. From the ethics of driverless car crashes to the impact on jobs, it might be that cars are about to rise up against us in ways that none of us are expecting.

The sea level in Venice has increased drastically in the last century or so, threatening the very existence of the city. Global warming and the harmful effects of tourism have amplified the phenomenon of acqua alta (sudden rise in sea level), rendering the traditional responses of inhabitants obsolete. It is urgent to act today. Projects conceived in laboratories across the globe are joining forces to save the city. These include RAMSES, a 3D modelization of the lagoon produced using lasers, which analyzes rises in water level; and MOSE, a series of movable dams costing over 4 billion euros, intended to block the sea in case of acqua alta. The film will take us on this extraordinary journey, the technological and scientific struggle for the survival of Venice, a survival that has been in doubt from its very construction.

Would mathematics exist if people didn't? Did we create mathematical concepts to help us understand the world around us, or is math the native language of the universe itself? Jeff Dekofsky traces some famous arguments in this ancient and hotly debated question.
Documentary that reveals the secret story behind one of the greatest intellectual feats of World War II, a feat that gave birth to the digital age. In 1943 a 24-year-old maths student and a GPO engineer combined to hack into Hitler's personal super code machine - not Enigma but an even tougher system, which he called his 'secrets writer'. Their break turned the Battle of Kursk, powered the D-day landings and orchestrated the end of the conflict in Europe. But it was also to be used during the Cold War - which meant both men's achievements were hushed up and never officially recognised.

Many clinical trials target the nation's most acute health issues. With deaths from liver disease soaring by 40 per cent in a decade, more and more patients are waiting for vital liver transplants. There is a shortage of organ donors and many donated organs are rejected as only those in excellent condition are considered suitable for a transplant procedure. Surgeons Richard Laing and Thamara Perera are part of a team at QEHB trialling a revolutionary way to tackle this crisis, by maximising the number of donor organs that can be safely re-used. The film follows the trial every step of the way, as Richard receives a donor liver that would usually be rejected and tries to prove it is viable for transplant by rejuvenating and testing it on a perfusion machine. This machine sustains the liver by mimicking the supply of blood, oxygen and nutrients an organ receives inside a live, healthy human body. Once the donor liver has proved itself fit for transplant, the surgical team start to remove grandmother Connie O'Driscoll's severely diseased liver. Once the donor liver has been disconnected from the perfusion machine, they have just 20 minutes to place it in Connie's body and plumb it into the complex and delicate network of hepatic blood vessels.
