What will be the biggest breakthrough of the next 50 years? As part of our 50th anniversary celebrations we asked over 70 of the world's most brilliant scientists for their ideas.

In coming decades will we: discover that we are not alone in the universe? Unravel the physiological basis for consciousness? Routinely have false memories implanted in our minds? Begin to evolve in new directions? And will physicists finally hit upon a universal theory of everything? In fact, if the revelations of the last 50 years are anything to go on - the internet and the human genome for example - we probably have not even thought up the exciting advances that lay ahead of us.
