Say It Ain't So, Picasso

Historians have long believed that Pablo Picasso produced some of his works with ordinary house paint.  Now, thanks to scientists at Argonne National Laboratory, there is proof.  Using a synchrotron light source capable of viewing the nano-scale structure of just about any material, Argonne scientists were able to match samples from Picasso's paintings to that manufactured by the French company Ripolin.  So...to all you Picasso owners...pretty cool huh!
