The prize has a £10m fund to be awarded for solutions to one of the most important problems of our time.
The public will choose the issue they would most like to be solved from a choice of 6:
1) How can we ensure everyone can have access to safe and clean water?
2) How can we ensure everyone has nutritious, sustainable food?
3) How can we restore movement to those with paralysis?
4) How can we prevent the rise of resistance to antibiotics?
5) How can we fly without damaging the environment?
6) How can we help people with dementia live independently for longer?
The original Board of Longitude was a committee set up in the 18th century to judge ideas for measuring longitude to enable navigation. The new committee for the 2014 Longitude Prize will judge ideas for solutions for the problem chosen by the public. The committee is chaired by Lord Martin Rees, the Astronomer Royal. Other members include Dr Philip Campbell, Editor in Chief of Nature, Iain Gray, Chief Executive of the Technology Strategy Board, Professor Dame Sally Davies, the Chief Medical Officer and Sir Mark Walport, the Chief Scientific Advisor.
