Life returned to something resembling normal after Covid but other crises soon took its place. These great challenges are also being felt at the University and our researchers are working on solutions. The nitrogen crisis, problems with young people’s services and an increasingly urgent climate crisis:…

For four years, Vicky Beckers examined thin slices of wood under a microscope, mapping the anatomy of two plant families. Her research helps identify different wood species, benefiting both the timber trade and archaeology.

A mega-dam around Europe is a possible solution as protection against rising sea levels. Whether that is really a good idea, was debated on by young professionals during the debate on the future of European coastal protection. 'A big dam may seem safe, but actually isn't,' argued debate winner Haye…
