PathOS aims to contribute to a better understanding and measurement of Open Science impacts and their causal mechanisms. This is pivotal in order to develop effective OS policy in the EU (European Union). It will do so by collecting concrete evidence of OS effects, by studying the pathways of OS practices,…

In this project, we aim to develop mathematical models to mechanistically and quantitatively predict the dynamics of cellular stress pathway activation and its relation with toxic effects when cells are exposed to various toxicants.

Should the media refer to a criminal’s ethnicity? Law students held an online afternoon symposium on discrimination in the criminal justice system – and, while they were at it, society at large.

A group of chemists, that includes Sander van Kasteren and Hermen Overkleeft, has discovered that azides, a certain type of chemical compound, can determine whether or not T cells respond to or ignore a vaccine. Their discovery is set to be published in Angewandte Chemie.

How does the photoregulation mechanism work in detail?

NWO-ALW has funded the project Climate impact on human evolution: age calibration of the ICDP Hominin Sites and Paleolakes Drilling Project (HSPDP), led by PIs Cor Langereis and Guillaume Dupont-Nivet (Utrecht University).

Missiles that travel at approximately six thousand kilometres per hour, up to 5 or 6 times the speed of sound. Has Russia used those against Ukraine and how is that possible? In Leiden University’s Dutch video series ‘De Werkplaats’, Danny Pronk, political scientist, security expert, and researcher…

This perspective addresses four challenges facing theorists whose aim is to make quantitatively accurate predictions for reactions of molecules on metal surfaces, and suggests ways of meeting these challenges, focusing on dissociative chemisorption reactions of H2, N2, and CH4.

Last Thursday the Dutch House of Representatives held a debate on children being put into care when the childcare benefits scandal (toeslagenaffaire) had caused problems for their families. Four Leiden University academics were asked by the House to produce a fact sheet for this debate, bringing together…

PhD defence

Researchers of the Leiden Institute of Advanced Computer Science (LIACS) have started a 4 year project on developing a system that sends out automatic alerts when components from engines are showing first signs of fatigue.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

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.

Is private law ready for the challenges of our time?

Political scientist Nicolas Blarel (Leiden University) analsyses how non-state actors can (directly or directly) attempt to provoke conditions for a crisis between state actors that have nuclear capabilities. He argues that there is an urgent but complicated and understudied task to understand and manage…

An accurate description of reactive scattering of molecules on metal surfaces often requires the modeling of energy transfer between the molecule and the surface phonons. Although ab initio molecular dynamics (AIMD) can describe this energy transfer, AIMD is at present untractable for reactions with…

This thesis is a collection of experimental attempts to enhance photoluminescence of fluorescent molecules and quantum dots with single gold nanorods (GNRs) and relevant applications.

Dutch coalition parties VVD and CDA want to tighten asylum policy and have launched a plan to grant two types of statuses to refugees. They also intend to partially restrict the right to family reunification. However, this plan is facing strong opposition. With the proposal, the government can expect…

An international team led by Leiden astronomers has taken the first-ever image of a young, Sun-like star accompanied by two giant exoplanets. The researchers used The European Southern Observatory’s Very Large Telescope for this, known as ESO’s VLT. Images of systems with multiple exoplanets are extremely…

The student loan system, implemented in 2015 in part to improve the quality of Dutch education, is facing political backlash. Despite having signed the student loan system agreement in 2015, both GroenLinks and PvdA have had a change of heart.

PBDL favors multidisciplinary research. Depending on the problems under investigation, PBDL establishes collaborations between experts from for example molecular genetics, molecular and electro cell physiology, biochemistry, organic chemistry, analytical mathematics, mathematical statistics and computational…

The Faculty of Humanities will introduce a new assessment system in the next academic year. Marcel van Brunschot, the project leader for the digital assessment migration, is responsible for overseeing the transition to ANS.

Research in Leiden University’s Institute of Political Science focuses on the dynamics and the interaction of political institutions, individual decision-making, and collective behaviour.

This project, South American population history revisited: multidisciplinary perspectives on the Upper Amazon (SAPPHIRE), investigates population dynamics in western South America on the basis of traces in the geographical, genetic, archaeological, ethnological, and linguistic record.

Ten years ago, a new reward system was introduced in Dutch prisons: the only way prisoners could earn extra ‘freedoms’ was through good behaviour. Jan Maarten Elbers concludes that this system does little to encourage behavioural change and can even be counterproductive.

Rogier Creemers, assistent professor in Modern Chinese Studies, wrote an article about China's social credit system in the Schweizer Monat. In the article he argues that it is not the most dangerous among China's technology projects.

The database research community has made tremendous strides in developing powerful database engines that allow for efficient analytical query processing.

The Oxford Handbook of Dutch Politics provides a comprehensive longitudinal overview of the state of the art of academic research on the Dutch political system: its origins and historical development, its key institutions, main fault lines, pivotal processes, and key public policy dynamics. In each…

We focus on a better understanding of the mechanisms of cancer drug resistance and metastasis.

The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

Leiden University researchers and their collaborators report the development of new research frameworks that use day-to-day smartphone behavior gathered from a large sample of healthy people to help understand aging, and how aging alters with epilepsy and stroke.
