Leaf-eating caterpillars greatly enrich their intestinal flora by eating soil. Even effects of plants that previously grew in that soil can be found back in bacteria and fungi in caterpillars. Researchers from the Netherlands Institute of Ecology (NIOO-KNAW) and Leiden University write about this discovery…

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.

The 17th Symposium on Insect-Plant relationships in Leiden is open for registration. It will be held online from the 25th to the 30th of July 2021. We had to postpone the conference due to the Covid-19 pandemic and it will be held online now. The Symposium on Insect-Plant relationships has a long…

We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

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.

The Institute of Biology Leiden (IBL) is an internationally oriented institute for research and education in biology.

Can drug screening for tuberculosis treatment be made more efficient?

The subject areas covered encompass functional genomics, signal transduction, cellular differentiation, development, host-microbe interactions and animal behaviour.

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…

A Vici grant and a Science-GROOT: scientists from the Institute of Biology Leiden have been awarded prestigious grants from the Dutch Research Council (NWO). From investigating bacteria without cell walls to harnessing plants with the help of microorganisms.

The new project INFLANET will train young scientists in Europe to become experts in inflammation research. Professor Annemarie Meijer from the Institute of Biology Leiden coordinates the training.

The aim of this research is to gain insight into the approaches of learning to teach. Teacher learning processes, feedback in novice-expert interaction and the impact of the interaction are explored.

The aim of this project is to explore the use of statistical interaction models to quantify cross-omics and omics-drug interactions in large-scale clinical and experimental datasets

In tracing intra-site, local and regional craft networks in Late Bronze Age Tiryns (Greece) the project aimed to understand technological changes, (dis)continuities and social practices from the Late Palatial until the Post Palatial periods in Mycenaean Greece.

In this thesis, classes of strongly interacting quantum field theories, have been studied.

Nature is a never-ending source of inspiration for the researchers at the Institute of Biology Leiden (IBL). Based on a better fundamental understanding of nature, they are able to seek solutions in the area of health and biodiversity. The theme of IBL is ‘Harnessing biodiversity for health.’

Can we distinguish the effects of pesticides from other abiotic and biotic factors that occur in the field? And how do these factors interact with pesticides?
