21 DNA-inspired double helix sculptures have appeared across London as part of Cancer Research UK’s campaign to raise awareness and funds for the Francis Crick Institute, a world-leading centre of biomedical research and innovation due to open in 2016.

Blue Badge Tourist Guides who take their groups through the British Museum will often stop to point out some massive Assyrian sculptures before moving on to the nearby Parthenon Marbles. These represent the half-lion half-man figures guarding the entrance to the royal palace of King Ashurnasirpal the Second and were built in the ninth century BC. Now they can point out a modern version of the same creatures made from date syrup cans standing right in the centre of London – on the fourth plinth of Trafalgar Square.
