Edvard Munch's The Scream needs to practise physical distancing, say experts

Art lovers may have to give 1910 version space due to damaging effect of humidity on impure paint

It is a masterpiece that seems to speak to the later horrors of war in the 20th century and even the anguishes of the 21st. Now Edvard Munch's The Scream has another claim on modernity, after it emerged that an oversight by the artist means the 1910 version of the work needs to practise some physical distancing.

An international consortium of scientists seeking to identify the main cause of deterioration of the paint in the canvas has discovered Munch accidentally used an impure tube of cadmium yellow which can fade and flake even in relatively low humidity, including when breathed upon by crowds of art lovers.
