The Basics and Applications to Plant Sciences will be held physical. See below for more information.

What makes some international organisations more likely to succumb to crises where others manage to survive or even thrive? And what can international organisations do to become resilient and withstand existential challenges? Political Scientist Gisela Hirschmann (Leiden University) studied the example…

Two bacterial species team up inside the plant root system to rescue their host from fungal infection. This was discovered by a team of microbiologists and bioinformaticians from the Netherlands Institute of Ecology, Wageningen University, and the Institute of Biology Leiden. They also identified the…

Can metabolomic profiling be used to predict resistance against insect herbivores in plants?

The Indonesian Experience after the Fall of Suharto

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

Is translocation of nucleases possible via Agrobacterium T4SS and is it efficient enough for mutagenesis?

This book focuses on policing in city-regions in Europe bringing together experts from across the continent to develop a sociology of urban policing and a unique methodology for comparing different metropolises in the same country.

The Netherlands is losing plant species that rely on pollination by insects. Leiden environmental scientist Kaixuan Pan demonstrates this after analysing 87 years of measurements from over 365,000 plots. The news is alarming for our biodiversity and food security. ‘75 per cent of our crops and 90% of…

Choice is at the very heart of politics. War or peace, left or right, liberty or security, sovereignty or integration, consensus or conflict: choices matter. Study power and politics as they impact everyday lives in a topranked, selective programme. By doing a master's in Political Science in Leiden…

Development & Disease is one of the four research themes of the Institute of Biology Leiden.

Mari Nakamura defended her thesis on 14 March 2017

Just like every other organism on Earth, plants’ ultimate goal is to survive and reproduce. In order to achieve this, they must make trade-offs between where and how to allocate their finite set of resources. Whether they put their resources and energy into their growth, reproduction or maintenance,…

Dutch politics has long been a paragon of stability. Think, for example, of our party system until, say, the last decade. At the same time, we also see occasional changes and significant shifts. Society has changed and this is reflected in, among other things, how we vote and how policy is made. About…

25 years after the publication of Derrida’s Politics of Friendship (Politiques de l’amitié, 1994), this edited collection gathers 23 critical chapters that revisit this underappreciated text. Engaging closely with Derrida’s text, the contributors analyse, extend and critique the work. They reconsider…

The master's programme in Philosophy: Moral and Political Philosophy at Leiden University offers an excellent opportunity to explore fundamental issues in moral and political philosophy.

The Global Politics of Confucianism, a monograph contracted with Columbia University Press, analyzes the interaction between Confucianism and globalism in past and present, using history to critically engage Confucianism’s place in contemporary international relations and policy debates.

A collaboration between the IBL and LUMC has resulted in the discovery that the polymerase theta enzyme is essential for the integration of Agrobacterium T-DNA into the genome of plants. The finding means a break-through for the development of more efficient systems for targeted genome modification…

Beautiful microscopic specimens play the leading role in the course 'Biodiversity Plant' for first-year Biology students. Normally these are put back in storage right after the course. But not this year!

In the unique two-year international joint Master’s programme in European Politics and Society (EPS) you will be able to study at four major European research universities in the cities of Prague, Leiden, Krakow and Barcelona.

The Khoesan were the first people in Africa to undergo the full rigours of European colonisation. By the early nineteenth century, they had largely been brought under colonial rule, dispossessed of their land and stock, and forced to work as labourers for farmers of European descent.

Plants not only sense when they are touched, but they can also adapt to it. For example, by strengthening or defending themselves. But how do plants do this? The Green TE (Green Tissue Engineering) consortium has been granted a Gravitation grant of almost 23 million euros to investigate exactly this…

Let’s get this out of the way: Hillary Clinton won the 26 September 2016 presidential candidates television debate. Handily.

Political scientist Wouter Veenendaal received an NWO Veni grant for his research on the political stability of small states. 'I find small states fascinating, they are almost always excluded from comparative research, while in fact they often challenge existing theories in political science.'

Leiden researchers have compiled information collected by scientists over the past 120 years into a database of plant-fungal interactions. This important biological data is now freely available for researchers and nature conservationists. Publication in New Phytologist.

Plants can’t run away from enemies. Still, it would like to keep life-threatening herbivores at a distance. This can be done with odours. Klaas Vrieling of the Institute of Biology Leiden found out with his team how plants change odour production to keep the munchers at a distance.

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