Brave New World with Stephen Hawking

Episode 2

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. Anatomist Joy Reidenberg discovers two possible solutions to the killer disease malaria and - most extraordinarily of all - Aarathi Prasad meets a woman whose life has been saved by a revolutionary new cancer treatment, in which every patient gets an individually tailored cocktail of drugs. From the jungles of Cameroon to the quads of Oxford, the programme celebrates the work of scientists striving to extend and save our lives.

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. Designer Max Lamb witnesses the dawn of a new era in manufacturing where lasers are printing objects in 3D, and Stephen Hawking charts the rise of the former internet entrepreneur who is transforming space exploration. Environmental scientist Tara Shine visits an experimental new city in the desert where the citizens get about by unmanned pod car, and Kathy Sykes descends two kilometres underground to explore how scientists are using technology to study the most mysterious particles in the universe. From spaceship factories in California to one of the world's largest subterranean laboratories in northern Canada, the programme uncovers the technology that is shaping our future.
