Oceans: what remains to be discovered?
Brian Cox and Robin Ince are joined by Andy Hamilton, Professor Jon Copley and marine biologist Helen Scales, as they look at the riches still remaining to be discovered deep within our oceans. The deep ocean remains the last great unexplored frontier of our planet, and as Brian and Robin discover, what we might find there could provide us with some extraordinary insights and applications. We've only just begun to touch the surface, literally, in terms of identifying and learning about the huge and varied life forms that live in our oceans -from the microbes that could inspire and generate new drugs to fight antibiotic resistant diseases, to the deep sea snails with iron clad shells, that may lead to the development of new super-strong materials. Even the humble limpet is providing inspiration to material scientists and engineers: the limpets' teeth, it turns out, are made from the strongest natural substance on the planet.
