Leonardo: The Man who Saved Science

Leonardo da Vinci is well known for his inventions as well as his art. New evidence shows that many of his ideas were realized long before he sketched them out in his notebooks-some even 1,700 years before him! Of these “inventions” Leonardo never affirmed that his projects came from his original ideas. The film features drawings of his most famous ideas and inventions some of which trace their original creation to ancient Greece while others were a product of the scientific inventions of golden age of Islamic learning. This knowledge seemed to be lost in Europe during the Dark Ages until the Renaissance when Leonardo recovered it.

Mysteries of the Unseen World

Mysteries of the Unseen World transports audiences to places on this planet that they have never been before, to see things that are beyond their normal vision, yet literally right in front of their eyes. Mysteries of the Unseen World reveals phenomena that can't be seen with the naked eye, taking audiences into earthly worlds secreted away in different dimensions of time and scale. Viewers experience events that unfold too slowly for human perception; They "see" the beauty, drama, and even humor of phenomena of that occur in the flash of a microsecond; They enter the microscopic world that was once reserved only for scientists, but that Mysteries of the Unseen World makes accessible to the rest of us; They begin to understand that what we actually see is only a fraction of what there is TO see on this Earth. High-speed and time-lapse photography, electron microscopy, and nanotechnology are just a few of the advancements in science that now allow us to see a whole new universe of things, events, creatures, and processes we never even knew existed and now give us new "super powers" to see beyond what is in front of us. Visually stunning and rooted in cutting-edge research, Mysteries of the Unseen World will leave audiences in complete thrall as they begin to understand the enormity of the world they can't see, a world that exists in the air they breathe, on their own bodies, and in all of the events that occur around them minute-by-minute, and nanosecond-by-nanosecond. And with this understanding comes a new appreciation of the wonder and possibilities of science.

Are We Still Evolving?

Dr Alice Roberts asks one of the great questions about our species: are we still evolving? There's no doubt that we're a product of millions of years of evolution. But thanks to modern technology and medicine, did we escape Darwin's law of the survival of the fittest? Alice follows a trail of clues from ancient human bones to studies of remarkable people living in the most inhospitable parts of the planet and the frontiers of genetic research, to discover if we are still evolving - and where we might be heading.

Pop: The Science of Bubbles

Physicist Dr Helen Czerski takes us on an amazing journey into the science of bubbles. Bubbles may seem to be just fun toys, but they are also powerful tools that push back the boundaries of science. The soap bubble with its delicate, fragile skin tells us about how nature works on scales as large as solar system and as small as a single wavelength of light. Then there are underwater bubbles, which matter because they are part of the how the planet works. Out at sea, breaking waves generate huge plumes of bubbles which help the oceans breathe. From the way animals behave to the way drinks taste, Dr Czerski shows how bubbles affect our world in all sorts of unexpected ways. Whether it's the future of ship design or innovative new forms of medical treatment, bubbles play a vital role.

Fully Charged

Saiful explores one of the most important issues facing the modern world - how to store energy. He tackles his toughest challenge yet - trying to work out how to store enough energy to power a mobile phone for a whole year and still fit it in his pocket!

2016 • Supercharged: Fuelling the FutureScience

People Power

Saiful investigates how humans as living pulsing machines actually use energy, asking whether it's possible to 'supercharge' the human body and increase its performance. Live experiments explore everything from the explosive potential of everyday foods, to what we put into our bodies (and what comes out!), as well as how we measure up to the machines we use every day. Saiful even experiments on himself, showing images captured inside his own stomach. Every single one of us is an incredibly sophisticated energy conversion machine, finely tuned over millions of years of evolution. So will we ever be able to improve the human body's performance? Can we ever do more with less energy?

Let There be Light

Saiful investigates how to generate energy without destroying the planet in the process. Saiful begins his lecture by being plunged into darkness. Armed initially with nothing but a single candle, his challenge is to go back to first principles and bring back the power in the energy-hungry lecture theatre. Along the way he explains what energy is, how we can transform it from one form to another, and how we harness it to power the modern world. A fascinating and stimulating celebration of the stuff that quite literally makes the universe tick - the weird and wonderful world of energy.

The Science of Laughter

Comedian Jimmy Carr takes over Horizon for this one-off special programme, produced as part of BBC2's sitcom season. Jimmy turns venerable documentary strand Horizon into a chat show, with eminent laughter scientists as guests and a studio audience to use as guinea pigs. Jimmy and his guests try to get to the bottom of what laughter is, why we enjoy it so much and what, if anything, it has to do with comedy. Between them, and with the help of contributions from other scientists on film, Jimmy and guests discover that laughter is much older than our species, and may well have contributed to making us human. With professors Sophie Scott, Robin Dunbar and Peter McGraw.

Ice Station Antarctica

Antarctica is the last great wilderness. It's the coldest, windiest, driest and most isolated place on Earth. And every winter, for over three months of the year, the sun never rises. But it's also home to the British Antarctic Survey's Halley Research Station. A veteran of living and working at Halley in the early eighties, BBC weatherman Peter Gibbs makes an emotional return to the place he once called home. A place that, during his time, was key to the discovery of the ozone hole. The journey starts with an arduous 12-day, 3000-mile voyage onboard the RRS Ernest Shackleton. Once on the ice shelf, Peter is delighted to finally arrive at the futuristic research station and marvels at the cutting edge science being done at Halley today. From vital discoveries about how our lives are vulnerable to the sun's activities, to studying interplanetary travel and the threat of man-made climate change. But Peter's journey is also something of a rescue mission. The research station's home is a floating ice shelf that constantly moves and cracks, and the ice shelf has developed a chasm that could cast Halley adrift on a massive iceberg.

Birth of Life (Planet Science)

What are the origins of life? How did things go from non-living to living? From something that could not reproduce to something that could? Earth is estimated to be about 4.5 billion years old, and for much of that history it has been home to life in one form or another. Our planet is teaming with life, from the highest mountain to the deepest ocean; life is everywhere. But what was the firing pistol that started the evolutionary race? How did material go from non-living to alive? It's one of the most fundamental and difficult questions that has challenged us since the beginning of time.
