Each year, poppies disperse seeds that grow into a new generation of flowers. Sometimes, some of the seeds postpone their germination for a few years, for example when they’re covered by a layer of sand. Only when the sand disappears, do they start to sprout. Margriet Oomen did mathematical research…

A new study from Leiden researchers shows that the carbon emissions of building materials are set to grow if we do not act rapidly. Even with known interventions implemented in concert, these emissions are much larger than the remaining 1.5 degree budget for building materials at today’s share, the…

Urbanisation is steadily increasing with estimates expecting that 68% of the global population will live in cities by 2050. To accommodate the rural to urban transition, large quantities of land are transformed from natural to urban lands.

What are the conditions under which coercive diplomacy can compel a State to abandon its nuclear weapons program?

Henk Versnel's work on ancient religion has been seminal. For his 80th birthday, a group of scholars assembled to celebrate and analyze his oeuvre.

The 2011 disasters precipitated widespread concern among heritage scholars about the fate of Tohoku’s cultural properties, tangible and intangible. Damage to not only buildings and landscapes but also ‘formless’ heritage, some worried, could weaken social infrastructure and thus slow or undermine re…

Mechanical metamaterials are carefully engineered materials whose properties are controlled by their structure, not by their composition, which allows using metamaterials to study and control physical effects in detail⁠.

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.
