This edited volume provides a synthesis on the question of business attitudes towards and its influence over the development of the modern welfare state. It gathers leading scholars in the field to offer both in-depth historical country case studies and comparative chapters that discuss contemporary…

This project explored the role of material culture, in casu painted plaster and its technologies, in expressing dynamic social identities and in forging complex interwoven human relationships in the context of the Middle to Late Bronze Age of the Aegean and East Mediterranean.

When the immune system attacks cancer, the tumour modifies itself to escape the immune reaction. Researchers at LUMC published on this subject in Nature on 28 June.

On 22 June, Najib Amin defended the thesis 'State-building, lawmaking, and criminal justice in Afghanistan: a case study of the prison system’s legal mandate, and the rehabilitation programmes in Pul-e-charkhi prison'. The doctoral research was supervised by Jan Michiel Otto and Pauline Schuyt.

Practical applications for the reconstruction of the past

Cathodic corrosion for producing nanoparticles was (re)discovered when trying to control the electrochemical etching of a scanning tunneling microscopy (STM) tip.

Are Weyl particles the ideal conductors? Do cells without a cell wall play a role in chronic Tuberculosis infections? Carlo Beenakker and Dennis Claessen want to answer these questions. They both received a KLEIN grant from the NWO. With these grants, NWO wants to stimulate innovative, fundamental r…

Three speakers, three fascinating science stories and a well-filled lecture hall. The Niko Tinbergen Lecture had a successful restart on 10 December 2019.

The research addresses the question of “what is the impact of geopolitical changes to the pivot states in the Middle East? With special focus on Turkey, Iran and Saudi Arabia.”

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

This book offers a comprehensive analysis of China's global resurgence and its effects on U.S. dominance.

Researchers from Leiden University Medical Center (LUMC) and Netherlands Cancer Institute (NKI) have discovered how specialised immune cells can detect and remove cancers that are ‘invisible’ to the conventional defence mechanisms of the immune system. Their work has been published in Nature. The findings…

Joost Beltman (LACDR, Leiden University) has provided novel insights in the way T cells migrate towards virus-infected cells. This was accomplished by a combination of experimental research in the group of Ton Schumacher (Dutch Cancer Institute, NKI) and computer simulations in collaboration with Rob…

Does foreign aid promote human rights?

Ramesh Ganohariti will examine legal identity in three post-Soviet aspirant states and outline four common scenarios in this article.

Lipid nanoparticles (LNPs) have enabled the success of mRNA vaccines but remain limited in broader therapeutic use by challenges in delivery efficiency, targeting, and mechanistic understanding.

The main aim of the project is to collect and update on a regular basis bibliometric and patent indicators that can be used to underpin and inform analyses pursued at the European Commission (EC) to assess European and national scientific and technological performance.

American pharmaceutical company Bristol Myers Squibb will be building a new (CAR-T) cell therapy facility in the Oegstgeest part of the Leiden Bio Science Park. The company will manufacture and develop CAR T-cell therapy for patients with blood cancer (leukaemia), for example.

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

On 28 February 2019, Kabir Duggal defended his thesis 'Principles of Evidence in Investor-State Arbitration, Burden, Standards, Presumptions & Inferences'. The doctoral research was supervised by Prof. dr. E. De Brabandere.

In this article, the authors explore why there is substantial cross-national variation in the level of regulatory clarity surrounding cryptocurrencies

In breast cancer, metastasis rather than the primary tumour is the cause of death. A lack of oxygen in the tumour cells promotes this metastasis, accompanied by a reprogramming of the cell's metabolism. PhD candidate Qiuyu Liu investigated these alterations to get more knowledge about the actionable…

The authors explore the decision-making processes and debates surrounding EU member states' troop contributions to CSDP military deployments.

In this book, Lydie Cabane examines the history of disaster management in South Africa.

Light can be used to apply forces on single cells. Focused lasers have been used by physicists to tweeze particles and to manipulate them. These so called “optical tweezers” can be used as mechanical phenotyping tools for characterising the mechanics of materials and living objects.

Leiden biophysicists have found a new possible way to attack cancer cells. They have located ‘sinkholes’ on the cells where receptor proteins disappear from the surface. If a drug could push these proteins towards those areas, it would kill the cancer cell.

This research project is funded by a subsidy from Instituut Gak.

The process of unification and the character of the union are the central topics of Magnanimous Dukes and Rising States. Robert Stein mirrors continuity and modernisation in Burgundian times with the bankruptcy of the former dynasties and the decline of feudal government. The powerful towns played an…

In this article, Martin Sievert and Jonas Bruder investigated whether and how administrative burdens influences citizens' perceptions of welfare policies and attitudes towards beneficiaries.

This new article by Monica Kaminska is part of a special issue for Journal of Cybersecurity, based on a selection of contributions from THe Hague Program for Cyber Norms' 2019 Conference.

Reputation literature has provided crucial insights about the evolution of the US regulatory state. Daniel Carpenter’s influential account painstakingly demonstrates the relevance of reputation to bureaucratic ‘power’ and to early institutional state-building in the US context. We argue that adopting…

Pericytes, the mural cells of blood microvessels, are important regulators of vascular morphogenesis and function that have been postulated to mechanically control microvascular diameter through as yet unknown mechanisms.

The first index to measure product safety, sustainability, and circularity, operationalising the EU’s (SSbD) framework.

The Altai region has yielded a cluster of Middle and Upper Paleolithic stratified sites that have been recently excavated using a multidisciplinary approach.

The RISIS project aims at creating a distributed research infrastructure to support and advance science and innovation studies. This will give the field a strong scientific push forward, and at the same time, provide a radically improved evidence base for research and innovation policies, for research…

The Leiden University Medical Center (LUMC) will start construction this year of the largest non-profit stem cell and gene therapy facility in the Netherlands, and one of the largest facilities in Europe. NECSTGEN – the Netherlands Center for the Clinical Advancement of Stem Cell and Gene Therapies…

With the rise of information and communication technologies, large amounts of data are being generated and stored in databases. In order to get a better grip on these large amounts of data, serious efforts are being made to discover patterns and relations in the data with the help of new techniques.…
