A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

In an innovative study, Radboudumc and LUMC jointly tested a candidate vaccine based on a genetically weakened malaria parasite. The results of this clinical trial, published in Science Translational Medicine, show that the vaccine is safe and elicits a defense response against a malaria infection.

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

This dissertation and the corresponding films and recordings presented here are an effort to distil an approach to performing the orchestral music of Johannes Brahms that is significantly different from what has hitherto been produced in the fields of both Mainstream Orchestral Performance Practice…

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

When foreign matter enters our body, our immune system has to make a choice whether or not to go on the attack. There are times when the system goes wrong, and we end up with an illness or an allergic reaction. Researchers at LUMC are trying to steer the immune system. The dossier on Immunity, Infection…

Leiden professor of Cellular Immunology of Parasitic Infections Maria Yazdanbakhsh receives the prestigious NWO Spinoza Prize this year. This, in many ways, border-crossing scientist contributes with her research to more effective vaccines against parasitic infections and better medication for inflammatory…

For nine years he worked on the three-volume standard work Plant Galls of Europe. It yielded 2300 pages about 10,000 species of European galls, abnormal outgrowths in plants caused by parasites. Hans Roskam from the Institute of Biology Leiden: ‘The abundance of galls says something about the natural…

This research cluster is a part of the Institute of Political Science’s research programme ‘Institutions, Decisions and Collective Behaviour’. Its members examine the sources, design, effects and contestation of norms, rules, institutionalised practices and formal organisations that operate across national…

The key subject of the research programme Cities, Migration and Global Interdependence 1500 - Now (CMGI) is Inequality (at local, national and global levels).

Environmental Humanities is one of the LUCAS research themes, bringing together members of the three LUCAS clusters.

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.

In October 2014 a new publication on artistic research has been launched. The book is called Artistic Experimentation in Music. An Anthology, edited by Darla Crispin and Bob Gilmore, and published by Leuven University Press.

What are the capabilities or limitations of traveling between islands and how does this reflect seasonal variation? Is it possible to show higher levels of connectivity between islands based on generated pathways between several sites on two separate islands?

This project studies the roles of prehistoric foragers in past ecosystems to establish the character of past “natural” landscapes and enhance the management of current ones.

Making sense of the world around us depends on the fundamental ability to parse the world into distinct objects and keep track of them. This process is defined as object individuation. Research indicates that it is not always easy for infants.

The key subject of the research programme Cities, Migration and Global Interdependence 1500-now (CMGI) is Inequality (at local, national and global levels). We study this from an intersectional perspective: gender, class, ethnicity or race, religion, sexuality, age, ability/disability, citizenship and…

When focussing attention, the neurotransmitters noradrenaline and acetylcholine play an important role. This new finding made by psychologist Stephen Brown provides clues for further research on how focussed attention comes about. Dissertation defence on 16 June.

From malaria parasites as a vaccine to how top-level bureaucrats reach their decisions: seven researchers from Leiden University have received a Vidi grant from the Dutch Research Council (NWO). This 800,000-euro grant will enable them to develop their own innovative line of research over the next five…

Three Leiden professors have recently been awarded the most prestigious scientific accolade in the Netherlands: Maria Yazdanbakhsh and Marc Koper have been awarded a Spinoza Prize and Judi Mesman a Stevin Prize. They received their prizes on 13 October.

Researchers at Leiden University Medical Center (LUMC) and Radboud university medical center have been given the green light to deliberately infect volunteers with malaria in order to test a highly promising vaccine on them.

Grammatical gender is famously the most puzzling of the grammatical categories. We have a solid typology of gender systems, yet exciting and unexpected patterns keep turning up which defy easy classification and straightforward analysis. Some of these question, stretch or threaten to cross the outer…

The Data-Driven Drug Discovery Network (D4N) is an initiative by researchers from Leiden University and collaborators to join efforts in applying and developing novel techniques from data science to drug discovery and related topics from bioinformatics.

KNAW has elected eighteen new members, including two professors at Leiden University and one who studied and obtained his PhD in Leiden. The New Academy members will be installed at a later date this year.

In this project we think about the relationship between territory and contagion. Tracing the historical, political, and conceptual linkages between territorial bordering and migration on the one hand and disease related phenomena like contagion, immunity, and inoculation on the other, we ask how the…

This research project studies the distribution and impact of medieval malaria in the Netherlands.

Researchers from all parts of the world will be in Leiden from 2 to 4 May for a major malaria conference. The Leiden University Medical Center (LUMC) is organising a two-day workshop on how vaccines can be tested safely in humans.

An international team of astronomers led by scientists from Leiden Observatory has for the first time characterised a dust disk surrounding a young super-Jupiter, which is either a giant planet or brown dwarf. They detected infrared emission from the disk which might indicate that moons may have formed.…

ESA’s Gaia mission has produced the richest star catalogue to date, including high-precision measurements of nearly 1.7 billion stars and revealing previously unseen details of our home Galaxy.

Neat strips of grass and perfectly manicured flowerbeds may look green and inviting, but they’re often not the best for nature. That’s why Leiden University is prioritising a comprehensive biodiversity plan over conventional greenery at the Leiden Bio Science Park (LBSP).
