What is a galaxy?
What are they made of and how many different types are there? Astrophysicist Peter Laursen explains.

Quinoa is exceptionally nutritious and robust – it even withstands extreme conditions of drought and salinity. A large new research project wants to uncover the mechanism that makes quinoa so resilient. This is meant to create the basis for future improvement of this unique plant.
COMMENT: It is nice when complex things can be reduced to something simpler. But sometimes you lose more than you gain – such as, for example, when scientific studies are violently shoehorned into two simple boxes: ‘significant’ and ‘nonsignificant’.

The H-index is an attempt at measuring the productivity and impact of researchers. This is an illustration of the universities’ shift from trusting researchers towards micromanagement, efficiency and competition.
