This week on Science Weekly presented by Ian Sample, we discuss the Longitude Prize 2014. Three hundred years after the first prize to discover a way of determining longitude at sea, a new set of challenges have been shortlisted and thrown open to a public vote to decide the one scientific and technical problem that merits the £10m prize fund.
Ian is joined by Guardian online environment editor Adam Vaughan, Observer Tech Monthly commissioning editor Nicola Davis and Dr Emily Grossman, educator, broadcaster and expert in molecular biology.
We also hear from two members of the new Longitude committee, Astronomer Royal Lord Martin Rees and the UK's Chief Medical Officer Dame Sally Davies, on the scientific challenges that could win the prize, and how the public – yes, that means you and me – can determine the nature of that challenge.
The public vote closes at 7.10pm on Wednesday 25 June:
