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.

What is the connection between materials with weak and strong gravitational interactions?

What role do parent-child interactions play in the development, maintenance and treatment of depression in young people?

Biological and behavioural measurements of parent-child interactions.

Which microorganisms live near and inside plant roots? How do they contribute to plant health? Can microorganisms be employed in plant protection?

How does global change across time and space lead to convergence and loss of variation or increasing diversity and conflict?

Fostering multi-polar perspectives that engage more connected, nuanced and pluralistic understandings of the world. Global Interactions encourages and supports research that provides significant new insights on these global processes across time and space.

Media & interaction is where artificial intelligence and machine learning meet philosophy, cognitive science, and the creative arts. Examples of research questions in this domain are: 'Can an algorithm be creative by human standards?', 'Can creative processes, such as composing music or writing poetry,…

Membrane proteins and membrane interactions of proteins are studied by spin label EPR. Intact, native membranes, vesicles of all sizes and nano-disks can be investigated, because the size of the object does not matter in EPR. Whereas solution NMR is limited to micelles (a few nm in diameter), by EPR…

Host-Microbe Interactions is one of the four research themes of the Institute of Biology Leiden.

Many biological processes occur by biomolecules coming together and organizing into specific clusters without being bound to each other. These interactions range from clustering, transiently interacting (kiss and run), or assembling to multimeric units that can only function in conjunction. The hydrogen…

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

Keeping in touch with others will benefit your studies and work.

Interaction between Legal Systems acknowledges that law-making and law enforcement are increasingly taking place on various levels: in a global context, in EU context, on a national level and in a private law framework. These levels influence each other, sometimes directly, on the basis of a hierarchical…

The lipid membrane is a basic structural component of all living cells. Embedded in this nanometer-thin barrier, membrane proteins shape the membrane and at the same time respond to the shape of the membrane.

The aim of this thesis is to study cell-cell interactions and the development of an assay to explore and quantify the exchange of membrane compounds.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

Duality, stochastic processes

It is well-known that humans have significantly transformed ecosystems since their adoption of agriculture. However, in a deeper past, prehistoric hunter-gatherers may already have altered and modified their niche in ways that had major impacts on ecosystems.

‘Children do not see color’ is an illusion, say experts. Professor of the interdisciplinary tudy of societal challenges, Judi Mesman, was interviewed by the Dutch news platform NU.nl to share her expertise on the subject of speaking to children about racism and discrimination. Prof. Mesman's main research…

The roles of shame, guilt and social access in adolescent aggression

Animal Sciences’ contributions to the Host-Microbe Interactions research theme focus on the interaction of animal hosts with pathogenic microbes but also the beneficial role of the gut microbiome.

In this thesis, the researcher developed a nanosystem based on the metallophilic Interaction between cyclometalated complexes.

Subproject of the NWO Smart Culture Grant research project 'The Critical Visitor'.

Microbial Sciences' contribution to the Host-Microbe Interactions research theme is to investigate how beneficial or disease-causing microbes associate and interact with their host.

Plant Sciences' contribution to the Host-Microbe Interactions research theme is to dissect how microorganisms and microbiomes interact with the plant host and the insects on those plants, and how these insights may be harnessed to improve plant growth and health, by steering microbiome composition and…

Every year, in the last month of the Islamic calendar, millions of Muslims from around the world come together in Mecca to perform the Hajj, the pilgrimage that all capable Muslims should perform at least once in their lives. In 2013, the National Museum of Ethnology in Leiden organised the exhibition…

In this thesis, the role of plant-mediated soil legacy effects in shaping aboveground plant-insect interactions was investigated.

The available tools for academic literature search return a list of ranked documents, which might not be ideal for some tasks. To facilitate these tasks, I am creating a visual representation of the academic search space where the user can browse academic topics.

Cardiovascular disease is the leading cause of death worldwide.

The 18th edition of SIP will be organised by Caroline Mueller at the University of Bielefeld, Germany. The 17th Symposium on Insect-Plant relationships in Leiden has been held online from the 25th to the 30th of July 2021.

On the 4th of June, Menghui Shi successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Menghui Shi on this achievement!

This thesis comprises four closely related interpretative studies and set out to answer the compound question: ‘How do teachers interpret their classroom interactions in terms of their pupils’ best interest?’

The studies presented in the work show the potential of the integrative use of biophysical data in defining the structural basis of protein interactions.

The thesis describes the use of electron paramagnetic resonance (EPR) spectroscopy, in continuous wave and pulse modes, to address the interaction of α-Synuclein (αS) with membranes and the aggregation of αS.

We examine how soil-derived legacy effects of plants structure natural ecosystems, determine aboveground plant insect interactions, and how we can use soil legacy effects to restore degraded ecosystems.

On 21 February 2019, Ruben Zandvliet defended his thesis 'Trade, Investment and Labour: Interactions in International Law'. The doctoral research was supervised by Prof. dr. N.J. Schrijver.

On December 13th, Maaike van Naerssen succesfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Maaike on this great result.

An archaeological/ethnohistorical study.

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

Much attention has been paid to the exchange of objects, ideas, and people in the Caribbean. Networks of interaction connected local communities across pan-regional scales, shaping indigenous socio-political integrations and their responses in colonial situations. This work examines the poorly understood…
