In this opinion article published in World Development, the authors present five research and policy priorities. While it is clear that ‘pluriversal’ designs need to guide the way forward (Kothari et al 2019), defining a set of key pillars can provide direction and purpose across this pluriversality.…

Big data promises to transform public decision-making for the better by making it more responsive to actual needs and policy effects. However, much recent work on big data in public decision-making assumes a rational view of decision-making, which has been much criticized in the public administration…

Atherosclerosis, in particular rupture of atherosclerotic plaques, is the underlying cause of most heart attacks or strokes and is the leading cause of death worldwide.

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…

Each month, we will interview a student or staff member from Leiden University about their work or studies in relation to sustainability.

In an innovative study, Radboudumc and LUMC jointly tested a candidate vaccine based on a genetically weakened malaria parasite. The results of this clinical trial, published in Science Translational Medicine, show that the vaccine is safe and elicits a defense response against a malaria infection.

The LUCDH foster the development of new digital research by awarding a number of Small Grants each year. COIn Grants support Infrastructure development. We congratulate our four successful awardees for 2026.

Nanoparticles can be used as delivery systems for both small molecules and macromolecules such as proteins, peptides or oligonucleotides. This thesis focuses on the use of liposomes, nanometric vesicles formed by a lipid bilayer enclosing an aqueous core. Liposomes are highly versatile delivery syst…

How can we make agricultural production systems more sustainable as the worldwide demand for healthy, safe food continues to grow? How can we develop healthy new food crops that have higher yields while requiring fewer harmful chemicals?
