Certainly not; they are using the ’Moon landers’ to measure whether innovative forms of agriculture reduce greenhouse gas emissions. Fleur van Duin works…

We know more together than alone. To increase our university’s impact on the region, we have to be open to the world outside. This is how we strengthen our ties and create new opportunities for teaching and research.

Some bacteria, it turns out, have proteins much like ours that organise the DNA in their cells. They just do it a bit differently. This is revealed by new research from biochemists at the Leiden Institute of Chemistry and the Max Planck Institute for Biology. The discovery helps us better understand…
