Early Modern Medievalisms: The Interplay between Scholarly Reflection and Artistic Production

The current resurgence of whooping cough is alarming, and improved pertussis vaccines are thought to offer a solution. Outer membrane vesicle vaccines (omvPV) are potential vaccine candidates, but omvPV-induced humoral responses have not yet been characterized in detail.

What motivates citizen scientists in the Schone Rivieren project to contribute? How does their motivation, attitude and knowledge change over the years? Are there differences in motivation and attitude between different groups of volunteers (clean up vs. monitoring; long-term vs. short-term)?

Sonorous phenomena are always on the verge of becoming something else. As it unfolds, sound constitutes spaces, mediates presence, articulates time.

How can mega sand nourishments, such as the Sand Motor, be designed and managed for optimal ecosystem services provision ?

The earth has more than 7 billion inhabitants, all of whom leave behind traces of pollution. However, not all forms of pollution have the same harmful effect. Leiden scientists help determine where we should put our priorities.

The activities of the Europa Institute (also known as the Department of European Law) are supported by ‘Stichting Europees Instituut’. This foundation was the first of its kind in both the Netherlands and Europe as a whole. Established in 1957, its aim was to ‘support and advance the study of scientific…

Imagine that you have a chronic skin condition, characterized by red patches of itchy, scaly skin. You regularly notice people staring at your skin and sense their reluctance to shake your hand. Or imagine that you have Parkinson's Disease, causing your hands to tremble and making it difficult for you…

Museums, Collections & Society stimulates research and education and raises ethical questions regarding the collections’…

Vaccines are an extraordinary category of biopharmaceuticals. They are usually prophylactic and come in many types, from whole bacteria to peptides and nucleic acids. They are very cost effective and almost every human on the planet is vaccinated. The latter mandates that vaccines have to be extremely…

SAILS likes to occasionally organise workshops about topics that relate to our programme. On this page you can find more information about previous workshops.

Human trafficking is a very topical social problem, which because of both its social and legal complexity, can only be studied in an interdisciplinary way. Combating human trafficking currently features high on national and international policy agendas.

Monday June 18th the department of European Prehistory of the Faculty of Archaeology started a five-year research (2018-2022) of two newly discovered barrow groups: Baarlo-De Bong and Venlo-Zaarderheiken (northern Limburg).

Learning from small data sets in machine learning is a crucial challenge, especially when dealing with data imbalances and anomaly detection. This thesis delves into the challenges and methodologies of learning from small datasets in machine learning, with a particular focus on addressing data imbalances…

How can we find novel natural products from Actinomycetes that act as growth modulators on mammalian cells? Can we harvest and develop the potential of these novel compounds for industrial and medical biotechnology?

Have you always wanted to use your own coffee mug at the university coffee machines but it was never accepted? We have good news for you!

Leiden archaeologists investigate how people in the past impacted their environment. Together with scientists, environmental scientists, and humanities experts, they use this information to draw conclusions about the present – and show what we can learn from it for the future.

Morphometric and morphological differences have been used extensively in the past to study domestication of the wolf and the origin of dogs. Certainly before genetic testing was performed, these methods were the only means to diverge both groups. But still now, when aDNA cannot be extracted, morphometry…

Archaic and Classical architectural terracottas constituted an integral part of the architecture of monumental buildings at Akragas. These objects therefore provide unique insights into the built environment of sanctuaries at this important Greek colony in Sicily. This research's multi-disciplinary…

Like any language, the natural sign languages of deaf communities differ from each other in their grammars and lexicons. A growing number of studies indicates that sign languages make use of the gestures of hearing speakers to build linguistic structure. This implies that variation and similarities…

Coming to and living in The Netherlands after Brexit.

Like any language, the natural sign languages (henceforth: SLs) of deaf communities differ from each other in their grammars and lexicons. A growing number of studies indicates that SLs make use of the gestures of hearing speakers to build linguistic structure. This implies that variation and similarities…

The Leiden Institute of Advanced Computer Science (LIACS) aims on doing applied research with partners. You can be involved in our research, and in the knowledge transfer of our research results.

Is the legitimacy of law and governance of multilevel jurisdictions diminishing? What is the significance of (diminishing) legitimacy for the effectiveness of law? These kinds of questions about the legitimacy of the supranational formation of law, its application, and the policy and governance based…

Social science research helps us understand human behaviour and social structures. These are determined by various factors, which makes the research complex and increases the likelihood of drawing the wrong conclusions. The choice of research method and analysis is therefore extremely important. It…
