Science copies how squid change colour
The gene which gives squids the ability to change colour and camouflage themselves has attracted the attention of geneticists at Cambridge University working in the new science of synthetic biology.
They have used standardised DNA sequences known as Bio-Bricks to recreate the gene so that future biologically engineered organisms could be given the same ability to change colour.
