After a decade of work, French scientist Pascal Cotte claims there are hidden portraits underneath the Mona Lisa — including one of a distinctly different woman. Art experts are sceptical.

Researchers at the University of California, Riverside, received an initial grant of $US25,000 from the National Endowment for the Humanities, which they will use to explore the effectiveness of cutting-edge facial-recognition technology in centuries-old portraits and other fine art.
