Hack Dog Vision To Keep Your Bones Safe

Can you hide your skeleton from a dog? Would you want to know the day you’ll die? Has evolution ever come close to producing a real fire breather? This week on Field Notes, Michael and Hannah test a T-shirt with a secret only humans can see, leading them into the strange world of colour vision, from colourblindness and tetrachromats to the remarkable eyes of the mantis shrimp. They also ask whether DNA could become the ultimate hard drive, visit a data-storage mountain in Pittsburgh and discover just how little space all of humanity’s writing might take up.
