Are you interested in ancient Egypt, the rich cultural heritage of Mesopotamia or bliblical Hebrew and Aramaic? Students of all faculties can follow electives of Ancient Near Eastern Studies without prior knowledge or special entry requirements. Archaeology student Annely Arends talks about her expe…

This work is dedicated to interpreting in cohomological terms the special values of zeta functions of arithmetic schemes.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

The Van Loon project sets out to safeguard the archives of Dutch archaeologist Maurits van Loon (Amsterdam, September 22, 1923 - Montpellier, October 12, 2006) and make them accessible for further study.

Dutch archaeologists are making three-dimensional virtual reconstructions of archaeological objects lost in the Syrian civil war.

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

Polls conducted by I&O research point to a political landslide. What's in store for the Netherlands? The polls show that the new party of MP Pieter Omtzigt is well-positioned for the upcoming election, with an expected 31 seats, but only 3 for the Christian Democratic Alliance (CDA) party. It is obvious…

How does environmental heterogeneity shape biodiversity across spatial and temporal scales?

Voters sent a clear signal in the recent Dutch provincial council elections with the 'monster' victory for the Farmer-Citizen Movement (BoerBurgerBeweging, BBB). This sign of ‘social resistance’ has consequences for the policy on nitrogen emissions, according to Geerten Boogaard, Professor of Local…

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

A portrait can inspire, intimidate or reassure the viewer. Leiden University has many portraits of professors and students, from the foundation of the University to the present day. What purpose do these portraits serve? The 'Facing Inspiration' exhibition in the Oude UB is about this question.

Dementia is a progressive disease, diagnosed at a relatively late stage when intervention may not be effective. Aim of the research is to study scans of brain networks to help discover the early network changes related to dementia. Early diagnosis may benefit effectiveness of future treatment.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

Erik Bähre has been elected to the board of the Society of Economic Anthropology of the American Anthropology Association. On top of this he has joined the scientific advisory board of the NIAS-Lorentz Program.

I will give a general introduction to the field of molecular electronics, its history, methods and challenges. I will also introduce the subject of my investigation and provide a brief outlook to the remainder of our thesis.

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

A semi-empirical version of the specific reaction parameter approach to density functional theory (SRP-DFT) has been remarkably successful at predicting dissociative chemisorption probability vs. incidence energy curves for reactions on metal surfaces. New quantum Monte Carlo (QMC) calculations on the…

More European countries are introducing border controls, clashing with the ideal of free movement within Europe. Daniel Schade, Assistant Professor of EU Studies at Leiden University, analyses this development in The Washington Post.

In this thesis three different topics in number theory are studied.

It was more than twenty years ago that the plan for a Japanese-Dutch dictionary was born. Now it contains over 65,000 words, and completion is tentatively coming into view. Dictionary makers Oscar Veltink and Hetty Geerdink-Verkoren talk about their enthusiasm for this decades-long mammoth task.
