As search teams scour the rubble in Nepal, a global digital humanitarian effort has swung into action. We hear about crowdsourcing efforts online to map the disaster, and find survivors.

Plus the smashed up art, which used to be worth millions, now featuring in a new exhibition in Chicago. Elka Krajewska is founder of the Salvage Art Institute in New York, and is curating the 'No Longer Art' show in Illinois. And our regular commentator Lucy Kellaway examines the art of the resignation letter.
