Boosting light-based computing

University of Twente spinoff company QuiX is currently developing a photonic chip using the quantum properties of light for carrying out complex calculations. The new chip, of which a first version is already operational, ...

New findings could lead to cheaper solar cells

At the atomic scale materials can show a rich palette of dynamic behaviour, which directly affects the physical properties of these materials. For many years, it has been a dream to describe these dynamics in complex materials ...

Evidence of capuchin monkeys using tools 3000 years ago

A team of researchers affiliated with several institutions in Brazil and the U.K., has found evidence of capuchin monkeys using stone tools as far back as 3,000 years ago. In their paper published in Nature Ecology and Evolution, ...

MUSE reveals a glowing ring of light in the distant universe

The MUSE instrument on ESO's Very Large Telescope in Chile has revealed very detailed halos of neutral hydrogen around distant galaxies. A new result zooms on a few such halos, one of them forming a large, almost-complete ...

In search of an undersea kelp forest's missing nitrogen
