Climate change, biodiversity loss and environmental pollution are urgent problems that call for close collaboration between lawyers and scientists. Dr Hilde Woker and Dr Jason Rudall, both Assistant Professors at Leiden University, are investigating the important interface between law and science.

How can zebrafish models be used to gain a better understanding of host-pathogen interaction mechanisms and to screen new drugs for infectious disease treatment?

We aim to develop a microfluidic platform that can parallelize testing the performance and characteristics of pure, mixed and environmental bacteriophage samples.

How do nonmotile microbes leverage communal motility?

Can we exploit the cell death machinery of the host to develop new host-directed anti-TB treatments?

Leiden astronomy Master's student Arend Moerman has received an A+ for his thesis research on the simulation of chaotic interactions of three black holes. The simulations, which he carried out together with his Leiden and Oxford colleagues, show that lighter black holes tend to slingshot each other…

Why do plants produces always produced so many slightly differing metabolites within a particular chemical class?

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

The applications of studying the early development of insects range from agriculture to material science.

What role do parent-child interactions play in the development, maintenance and treatment of depression in young people?

The way organisms develop from the initial single-cellular state to a complex final assembly like the human body, and how the final body is maintained throughout life, is one of the greatest mysteries and it’s understanding one of the biggest scientific challenges.

What’s really happening in the space between the cells in your body? With the Collagen Canvas project, students from Leiden University invite you to explore this question by blending science with art. This interactive artwork immerses you in the dynamics of the extracellular matrix—the invisible structure…

This week sees the first edition of the textbook Mouse&Manuscript published online. Mouse&Manuscript is a collection of interactive lessons on codicology and oriental manuscripts. Its aim is to stimulate teaching on codicology in and outside of the classroom, and to contribute to the disclosure of Leiden…

This dissertation investigates the rural communities of the Cananefates in the period of 50 to 300 AD.

How can Staphylococcus aureus bacteria subvert the host immune system?

Dr. Eduard Fosch-Villaronga from eLaw collaborates with researchers from the Indraprastha Institute of Information Technology Delhi (IIIT-Delhi) and University of Delhi (DU) in an effort to explore and reflect upon the potential legal, ethical and pedagogical challenges of deploying a social robot in…

Is private law ready for the challenges of our time?

What are the host immune defence mechanisms that control intracellular infections and how are these subverted by pathogens?

How can we manipulate the biotic and abiotic environment to increase thrips resistance in tomato and chrysanthemum? More specifically we ask: How can plant secondary metabolites that are not soluble in water be delivered to plants in seed coating or root dipping treatment? Can bacteria be used to…

Can we use indigenous microbial rice communities to reduce methane production in agricultural settings?

The Herta Mohr Building is leading the way in sustainable innovations, for both Leiden University buildings and beyond. It is the university’s first fully gas-free building and the new Thermal Energy Storage system alone will cut carbon emissions by 150,000 kg per year. The building has an ‘Excellent’…
