'E.Chromi' yoghurt makes your number twos coloured if you're sick


You can stop searching for a rainbow pooping unicorn now - if that's your thing - because scientists have come up with a way to bring that sort of colour to your very own toilet bowl. But the rainbow shades in your modified poo are all aimed at telling you how healthy you are or what could be ailing you. To do this Cambridge University students Alexandra Daisy Ginsberg and James King engineered bacteria to produce coloured pigments. The researchers designed DNA sequences known as "BioBricks" and inserted them into E.coli bacteria, producing red, yellow, orange, green, purple and blue colours.

Scientists envision their magic yoghurt could be in stores by 2039.
