Prison staff are working under high pressure. The current proposal for cell sharing is the final straw. Associate Professor Esther van Ginneken appeared on Dutch news programme ‘Nieuwsuur’: ‘Serious incidents have occurred, including the murder of a cellmate.’

Embryonic stem cells have the remarkable ability to develop into any type of cell. On their way to become for example a liver or a heart cell, they must repeatedly decide between alternative developmental paths. How they make these decisions is largely unknown. An international team of biophysicists…

The policies relating to language pursued by European monarchies and states have been widely studied, but far less attention has been given to their linguistic and cultural policies in territories outside their own borders.

The work presented in this thesis addresses the role of the locus coeruleus (LC) - norepinephrine (NE) system in various aspects of human cognition, and the modulation of brain state.

Smart digital infrastructures predicated on myriads of sensors distributed in the environment are often rendered as key to contemporary urban security governance to detect risky or suspicious entities before or during a criminal event takes place. At the same time, they often involve surveillance of…

On 20 March 2019, Tim Dekkers defended his thesis 'Mobility, Control and Technology in Border Areas: Discretion and Decision-making in the Information Age'. The doctoral research was supervised by Prof. dr. J.P. van der Leun en Prof. dr. M.A.H. van der Woude.

Leiden molecular cell biologists in the research group of Annemarie Meijer have discovered novel early macrophage-specific genes in zebrafish, including a signal transducer pivotal for the migration of macrophages in the innate immune response to bacterial infection. Their findings were published on…

Advancing the understanding of the interaction of light and matter on the single-quantum level is important for near-future quantum technologies but also to answer fundamental questions.

The research project ‘The History of National Security, 1945-present', is funded by the Netherlands Organisation for Scientific Research (NWO), the Campus The Hague/Leiden University and the Netherlands Institute for Military History (NIMH). The project will run until the summer of 2013, when we hope…

Leiden chemists, together with colleagues at the University of York (UK) and Technion (Israel) have discovered a small, sugar-like molecule that maintains the integrity of tissue around a tumour during cancer. This molecule prevents tumour cells from spreading from the primary cancer site to colonise…

What are the life-cycle environmental impacts and risks to human health and ecosystems of a III-V/Si PV system? How can these be expected to change when the system is deployed at industrial scale? What are the most favourable recycling scenarios?

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.

Leiden physicists are helping Wageningen plant researchers to study unpredictable plant embryos. For this, they are using a novel two-photon fluorescence microscope, aided by a 30 thousand euro ZonMW grant.

The Cinematic Santri explores the rise and course over the last ten years of cinematic practices among a younger generation of NU associates (Nahdlatul Ulama), the largest traditionalist Muslim group in Indonesia and elsewhere.

An international group of scientists has discovered that certain cells of our immune system – the so-called T cells – communicate with each other and work together as a team. To fight an infection they stimulate each other’s growth, but at the same time, they inhibit each other when there is a surplus…

With the necessary measures, researchers restart their work in various laboratories. The Leiden Cell Observatory is one of the places where scientists resume their lab work.

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.

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

What performance criteria does a new technology have to fulfill in order to be added to the list of future energy options and what constraints exist in terms of broad market penetration?

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.

Organizations often announce their protest activities prior to their implementation to mobilize awareness, recruit supporters, and receive media attention. We are interested in the effectiveness of protest announcements—that is, under what conditions governments make concessions to avoid having an announced…

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

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

What is the environmental impact, the human health impact and the life cycle and production costs of the lab, pilot and commercial diffusion of nanowires and nanowire-based photovoltaic technologies?

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

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…

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

Researchers from the Netherlands Cancer Institute, the Leiden University Medical Center (LUMC) and Oncode have created a tracking system that can reveal how often cells have divided. This allowed them to find a yet undiscovered population of immune cells: young memory cells that behave like stem cells.…

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…

New policies, institutional configurations, and state-market relations are emerging outside of East Asia, as new developmental states move beyond the historical experience of East Asian development. Yet, the ‘developmental state’ is still relevant. This book, edited by Jewellord Nem Singh (Institute…

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