Scientists in Switzerland can now read fragile documents without opening them. The Ecole Polytechnique Federale de Lausanne (EPFL), uses X-ray tomography to scan an entire book, page by page, without even touching it.
This is definitely a great subject for a documentary. The only thing I would say is we need to find something explosive. The technique is fascinating, but it needs to offer an insight into a document that changes our understanding of the world.
