In the large gas clouds between the stars, chemical reactions take place under extreme conditions, giving rise to both small molecules, such as water and common salt, as well as large complex molecules that can serve as the building blocks of life. This is known as astrochemistry and it is something…

Evaluaties en onderzoeksrapporten bieden waardevolle inzichten na crises, maar hoe zorgen we ervoor dat deze lessen daadwerkelijk leiden tot verbeteringen in crisisbeheersing en rampenbestrijding? Dit vraagstuk staat centraal tijdens de bijeenkomst Leren van crises: van onderzoek naar verandering, op…

The hinterland of important centres like Petra (Southern Jordan) can provide essential information that contribute to the understanding of their rise, expansion and decline.

GLOBOX is a spatially differentiated multimedia fate, exposure and effect model. It is used for the calculation of spatially differentiated LCA characterisation factors on a global scale.

Animal Sciences’ contributions to the Evolution & Biodiversity research theme include evo-devo research, the evolution of cognitive and behavioural traits, and the evolutionary mechanisms of stress adaptation. This research involves both indoor and outdoor studies.

The

The research within the Division of Cell Systems and Drug Safety, headed by Prof. Bob van de Water, is focused on novel therapeutic modalities and novel concepts in early drug discovery, in order to develop more effective and safer therapeutic strategies. We generate advanced cell and computational…

Overview of CML software and data

Leiden University has participated in an international study carried out by the CARMENES consortium, which has discovered two small, terrestrial planets around Teegarden’s Star. The planets have masses similar to Earth and their temperatures could be mild enough to sustain liquid water on their surf…

Can chemical safety assessment be improved with zebrafish embryo-based reporter assays?

This project investigates properties of quantity expressions across languages from the perspective of how quantity is represented in the human brain.

Artificial photosynthesis has recognised potential to produce green and sustainable fuels from earth-abundant resources such as water, carbon dioxide (CO2), and sunlight.

During the farewell reception on 29 August, the Faculty of Science will say goodbye to Dean Geert de Snoo. On 1 November 2019, he will continue his career as Director of the Netherlands Institute of Ecology (NIOO-KNAW). Colleagues talk about his significance for ecology, about his contribution as a…

How do you study complex disasters like a nuclear explosion or a natural disaster? Who can help unravel the legal knot that Brexit has become? The important societal themes of the present day call for interdisciplinary collaboration. Leiden scientists pitched their research at a symposium at Leiden…

What are interactive effects of human pressures on aquatic communities?

During the development of the Humanities Campus, many aspects of sustainability are combined. For example:

What happens to the different waste streams?

More severe droughts that will also last longer: this will primarily be a problem for irrigated croplands, as discovered by environmental scientist Qi Chen. Mixed forests with a variety of plant species will be the least vulnerable. Chen compared the effects of drought on different ecosystems across…

VVI Research Meetings 2023-2024

In June 2024 the Faculty of Archaeology welcomed a new Assistant Professor. Dr Jennifer Swerida, originally from the United States, will strengthen the Faculty’s expertise on the archaeology of West Asia. ‘I explore human-environment relationships inside an ancient oasis and the surrounding land. Previous…

Purple clothing and a pride flag flying from all University buildings: Leiden University is once again taking part in Purple Friday. How do people experience this day? We asked some employees and students of the Faculty of Humanities.

Excessive regulatory burden causes economic harm and can undermine trust in government. Policymakers wishing to ease this should be more mindful of people’s differing responses to rules, says PhD candidate Ritsart Plantenga in his dissertation.

In September 2023, we started transforming a under-utilised outdoor space into a greener and more biodiverse garden in which all students and staff of the Schouwburgstraat can relax and enjoy.

- How to deconvolute metabolic mixture of precursors and products by biontransformation? - How to optimize the reaction conditions to produce bioactive compounds in biotransformation? - What is the effect of co-treating fungi or bacteria for biotransformations?

Changes to halt further biodiversity loss are more urgent than ever and feasible, says IPBES, the United Nations biodiversity panel. In two reports released this week, the panel calls on governments worldwide to develop coherent policies that address biodiversity, climate change, water, food and health.…

In the summer of 2011, from June 14th until August 5th, the Laboratory for Human Osteoarchaeology conducted an excavation on the former cemetery of Middenbeemster in cooperation with archaeological company Hollandia. The cemetery, which is located next to the church of Middenbeemster can be dated between…

Plants, algae and cyanobacteria have the amazing capacity to perform delicate photophysical and photochemical processes of light capture, excitation transfer, charge separation and catalysis in fluctuating living environments. As a consequence, photosynthetic proteins and membranes form dynamic architectures.…

He started his career as a part-time PhD candidate and a reading volunteer at his children's school. Now, as a professor, he looks back on forty years of research and education: Peter Klinkhamer of the Institute of Biology Leiden, ecologist in heart and soul.
