He's no Father Christmas, but he is dressed in festive red and green, and he's made of bacteria. This image, Mario, was submitted to the 2009 international Genetically Engineered Machine (iGEM) competition by Team Osaka from the nanobiology laboratories at the University of Osaka, Japan.
They genetically engineered bacteria to express fluorescent proteins and carotenoid pigments to create works of art.

Have a great Christmas, everyone. We'll be back next week.
