Expect more discoveries in the future: The European Commission just greenlit MoLab to keep museum-hopping the continent for another four years.

five years on the road, MoLab has analyzed everything from a pre-Columbian Mixtec codex in the British Museum to expressionist paintings, such as Angst and Puberty, at the Munch Museum in Oslo.

MoLab can even track an artist's style and methods - in 2005, the team found a sketch for da Vinci's the Last Supper under the surface of another one of his paintings at London's National Gallery.
