Pursuing Whiteness in the Colonies offers a new comprehension of colonial history from below by taking remnants of individual agencies from a whiteness studies perspective. It highlights the experiences and perceptions of colonisers and how they portrayed and re-interpreted their identities in Afric…

The work described in this dissertation contributes to a better mechanistic understanding of nanoparticles in vivo. To achieve that goal, we used the zebrafish as a highly predictive pre-screening model of nanoparticles.

This thesis investigates a pharmacological challenge model induced by Toll-like receptor 7 (TLR7) activation, focusing on skin inflammation and its implications for early drug development.

On December 11th, Andreea Geambasu succesfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Andreea on this great result.

A global perspective

The experiments described in this thesis employ local lentiviral knockdowns in brain areas of female zebra finches followed by behavioural assays consisting of preference and Go/Nogo tasks.

In this project we study the properties of statistical- and rule-learning mechanisms in relation to the acquisition and evolution of language. We ask to what extent these mechanisms are unique to humans - or to human language - by comparing the acquisition of vocal structure in two species: humans (infants)…

Fish climbing trees, storks taking care of their parents… Premodern textual and visual culture presents us with a fabulous bestiary that reveals ingenious and rich reflections on the animal kingdom.

Provides a cutting-edge comparative political economy analysis of welfare and inequality across ten East Asian countries.

The Vallesian, 11.1-9 Ma, was a special time in the Vallès-Penedes basin near Barcelona, where a biodiversity hotspot existed. Europe had a subtropical climate, with rhinos, forest giraffes, lions, hyenas, flying squirrels and primates.

The zebrafish is a promising vertebrate model organism in early drug discovery and development.

“Temminck’s Order” is the scientific biography of Coenraad Jacob Temminck (1778–1850), a Dutch naturalist and the first director of ’s Rijks Museum van Natuurlijke Historie in Leiden.

There is concern about the threat that nanoplastics (NPs) may pose to both wildlife and humans. This thesis explores the mechanisms of toxicity of polystyrene nanoparticles (PS-NPs) in chicken embryo.

Death in all types of melanomas is generally caused by metastasis. Uveal melanoma (UM) is the most common intraocular melanoma, there are currently no (patient-derived) animal models that faithfully recapitulate metastatic dissemination of UM.

On Tuesday 10 September 2024 May Shaddel Basir successfully defended a doctoral thesis and graduated.

Does Artifical Light at Night (ALAN) disrupt seasonal physiological and behavioral patterns in migrating freshwater fish?

Heart failure is a major health care problem with high mortality.

The mycorrhizal symbiosis is among the most widespread species interactions on Earth⁠. This thesis focuses on orchid mycorrhiza, a unique mycorrhizal type that has caught scientists’ attention for centuries⁠.

The function of TLRs in innate immunity has aroused worldwide attention soon after its discovery. Because of the broad functions of TLR2 in innate immunity, the drive for the development of TLR2-targeted vaccines or therapeutic treatments has accelerated in the last decades.

Can we link multiple components from herbal extracts with their biological activities?

We study expressions of emotion and social decision making across species.

People who have taken antibiotics in the past three months pay more attention to negative facial expressions, according to research by postdoc Katerina Johnson and assistant professor Laura Steenbergen. This may explain how antibiotics increase the risk of developing depression.

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

We recognize the importance of communicating about our scientic work to the general public and we enjoy doing so. Recently, we received funding from the Pilot fund Science communication by scientists: Appreciated! (with members of Change Leiden) to engage children and adolescents in science communication…

How do mycobacteria subvert the defenses of host immune cells?

How do humans, non-humans and their interactions and relations shape the home as ecological and social space?

This ecological community has long been known to affect host biology, and their diverse roles have been further clarified in recent years following numerous studies of animal:microbiota interactions in diverse systems.

Our education programmes span the entire spectrum of Animal Sciences, Evolution, Biodiversity and Conservation, Microbial Biotechnology and Plant Sciences.

Central in this thesis are the various forms the research-teaching nexus can take in the university, especially in the Faculty of Humanities. The importance of a strong relation between research and teaching is advocated by many academics, but debate is going on about the forms this strenghthened relation…
