Non-urban settlement organization and Roman expansion in the Roman Republic (4th-1st centuries BC)

Leiden University and the Leiden Bio Science Park can make a significant contribution to the earning capacity of the Netherlands. This is the finding of the National Investment Agenda presented today.

Three new ministries have been formed in the Netherlands: Asylum and Migration, Housing and Spatial Planning & Climate and Green Growth. Of course, this is not merely an administrative act. These ministries carry a strong and political charge and play a crucial role in shaping a government's political…

Protest is a human right and an important way to hold the authorities to account. But how does the right to protest relate to academic freedom and the right to education?

Europe in lockdown: Member States acted on their own initiative to into lockdown, and all back to normal at the same time? It’s not that simple, and it doesn’t have to be.

The former Valkenburg airfield is steeped in history: the Romans defended their empire here, German forces landed here in 1940 and even the Cold War left its mark. Now thousands of homes are planned for the site. Students from Leiden and Delft are exploring how to make this past visible.

The Ra’s al-jinz project tackles economic diversification and social complexity in non-urban societies, from the perspective of Eastern Arabia, by exploring the Early Bronze Age settlement of Ra’s al-jinz RJ-3.

Frontex, the European Border and Coast Guard Agency, is currently facing serious criticism. Over a short space of time, it has been significantly expanded. And the larger the Agency becomes, the more often it comes under fire.

In the heart of The Hague stands the Peace Palace, home to one of the most important courts in the world: the International Court of Justice. PhD candidate Joris van de Riet spoke to 'Het Klokhuis' about the role of the Court.

Insurers determine for themselves whether someone has committed fraud, impose sanctions immediately and hardly ever report it. As a result, police, prosecutors, and criminal courts are side-lined. And policyholders are sometimes left out in the cold. Bart Custers, professor of Law & Data Science at…

Understanding DNA repair mechanisms is essential for advancing plant biotechnology and crop improvement. This study investigates how double-strand breaks (DSBs), induced by CRISPR/Cas systems, are repaired in the model plant Arabidopsis thaliana, and how these processes influence Agrobacterium tumefaciens…

Investigating the emergence of complex societies in Chalcolithic Cyprus.

How do the starchy botanical foodways reflect upon previous archaeological understandings in the northern and circum-Caribbean?

Evolution acts via mutations in amino acid sequences. Substitution of essential amino acids leads to a nonfunctional protein. l.

Annetje Ottow, president of the Executive Board of Leiden University, has been the new chair of the Leiden-Delft-Erasmus (LDE) strategic alliance for just two months. What does she want to achieve during her two-year chairmanship?

Political scientist Simon Otjes (Leiden University) receives a grant from The Dutch Research Council (NWO). The grant is part of the SGW Open Competition XS, which aims to stimulate innovative scientific research within the Social Sciences and Humanities domain. Otjes receives the grant for his research…

Law firms play a dubious role in important land disputes in Indonesia. They act as fixers and settle conflicts to the advantage of large companies. PhD candidate Santy Kouwagam studied their modus operandi. PhD defence on 23 June.

The sustainable production of hydrogen could potentially be made more efficient by adding a cleverly chosen salt to the process. Researchers at the Leiden Institute of Chemistry (LIC), in collaboration with physicists at the University of Twente, have discovered that the type of salt present in the…

This project uses archaeological, literary and epigraphic evidence to investigate urban development in Roman-period North Africa, compiling this in a GIS-linked database in order to analyse the development of urban settlement spatially over time.

Basketry, cordage and textiles made of plant fibers or bark are rarely preserved in the archaeological record. By means of experimental archaeology and microwear analysis, we obtain indirect evidence about this important craft.

The genetic material of currently living Europeans is partly of Neandertal origin. Were our ancestors successful because they were hybridising and interacting with the local populations they encountered when migrating into new places? Reconstructing our evolutionary trajectory is key for rethinking…

How does contemporary art and culture represent nuclear contamination in post-nuclear landscapes?

This project investigates ancient water management of streams, springs and runoffs on the archaeological site of Monte Albán, Mexico, as a means to contribute with different stakeholders in the development of sustainable solutions to water problems today such as floods and scarcity.

It is estimated that approximately 30% of all proteins require a metal to function. Investigating the relationship between metal-binding and peptide/protein folding allows us to uncover fundamental rules for creating metallo-peptides and proteins, which in turn leads to the creation of new structures,…

This project investigates the well-preserved agricultural terraces of the Inn valley and the evolution of resource use in the inner Alps.

Since 2013, the National Natural History Museum of the Netherlands, Naturalis Biodiversity Center, is unearthing the largest bonebed of the horned dinosaur Triceratops discovered so far. In order to answer questions about sedimentology, taphonomy and palaeobiology, palaeontologists and geologists collaborated…

This study aims to provide a long time perspective of human landscape manipulation. Studying the roles of prehistoric foragers in past ecosystems is of great importance to establish the character of past 'natural' landscapes and to enhance the management of current ones.

Researchers using remote sensing technologies have characterized pre-Columbian regularly-shaped earthworks in forests in Central America and the Amazon. In tropical forested mountains in South America, two challenges arise when identifying archaeological sites through remote sensing. Firstly, sites…

What does site patterning reveal about the social landscape dynamics across the historical divide?

Streptomyces present a valuable platform for natural product discovery. Lugdunomycin is a novel angucycline-derived polyketide from Streptomyces sp QL37, with unprecedented skeleton and antimicrobial activity.

Archaeometric analysis of glazed pottery assemblages from the Early Byzantine to the Early Modern periods in the Aegean.

Because of their large surface area and immunological competence, mucosal tissues are attractive administration and target sites for vaccination.

This handbook provides a resource for those already familiar with some kinds of micro-particles who wish to learn more about others, or for those just starting out in the study of microremains who wish to have a broad understanding about microscopic archaeology.

Middle Paleolithic stone tool technology is one of the major sources of information about Neandertal behavior and adaptations. The Balkan Middle Paleolithic often remains outside of the major debates and interpretations of Neandertal behavior.

Heterogeneous catalysis is essential to many industrial applications. These catalysts are often comprised of supported nanoparticles, which contain various different surface sites.

Patterns of paleomobility in the Caribbean were studied through an inter-disciplinary approach using a combination of archaeological, osteological, mortuary, and isotopic data.

Clara ten Hacken defended her thesis on 16 December 2015

The book explores how ceramic studies illuminate interactions among ancient Mediterranean communities. By integrating post-colonial perspectives and network analysis, the volume transcends traditional
