Professor Stephen Hawking presents a global exploration of the scientific breakthroughs that are transforming our lives in the 21st century.With the help of some of the world's leading scientific figures -including Sir David Attenborough, Richard Dawkins, Aarathi Prasad, Lord Winston and Maggie Aderin-Pocock -this five-part series reveals how science is striving for humankind's next leap forward.Machines. The team showcase breakthroughs in technology and engineering that are creating a new generation of machines. Mark Evans fuses his brain with a computer in Switzerland to test a new breed of machine. Kathy Sykes hits the streets of San Francisco to have the ride of her life as she experiences the future of transport in a driverless car.Health. The experts examine how scientists are fighting for our survival by battling the world's big killer diseases. Biologist Aarathi Prasad joins virus hunters in the jungles of Africa, Robert Winston sees first-hand how the surgeons of the future could be robots, capable of operating round the clock, and Richard Dawkins investigates the way brain disorders might one day be treated using laser light and genetically modified brain cells.Technology. The experts explore how 21st-century technology is shaping our future by changing the way we live, the way we communicate and our perception of the universe. Physicist Kathy Sykes explores how our mobile phones can give experts access to our every habit and action: a brave new world in which it's hard to keep a secret but where urban planners can build cities around our needs.Environment. Science turns superhero as it battles to save the planet and preserve the human race. In California, physicist Jim Al-Khalili sees how the power of the world's largest laser could create a fuel to answer all our needs, while at Longleat Sir David Attenborough helps collect the DNA of an elephant for the Frozen Ark -a project to save all the world's species from extinction.Biology. The experts unearth the amazing breakthroughs that are transforming the resilience and strength of the human body. Mark Evans joins the bio-prospectors in Central America exploring the untapped reserves of the oceans for life-changing drugs; Aarathi Prasad meets the remarkable old people who could hold the secret to a long and healthy life; and Robert Winston explores how our behaviour and environment may be influencing the genes of future generations in ways we once thought impossible.
