Thanks to a new generation multispectral digital camera developed by IST-project CRISATEL, treasured documents and fine art can be captured with high resolution and reproduced in extraordinary colour for analysis, restoration and conservation.
The multispectral (ultraviolet to infrared) capture technique, employed in the JumboScan camera manufactured by consortium member Lumiere Technology, is a leap forward from the 100-year old tricolour concept of analogue photography. This older concept does not capture the entire visible colour spectrum. It replaces a large range of colours widely used in fine art, such as blue (Cobalt blue PB36) and red (Vermillion PR10), with other colours.
The JumboScan camera enables multispectral image acquisition that covers up to 95 - 100 per cent of the visible colour space versus the 50 - 70 per cent from the traditional RGB (red, green, blue) mode. "This means each pixel receives enough information to guarantee perfect colour restitution," says Pascal Cotte, CRISATEL project manager and president general manager at Lumiere Technology.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
