IBL-researchers revealed in a new study that insects are successful on land because their eggs became protected against desiccation. An extraembryonic membrane in the egg, the serosa, helped insects to make the transition from water to land.

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…

The chemical industry must continue to innovate for a more sustainable, healthier society. The reseachers from the Leiden Institute of Chemistry (LIC) contribute by applying their knowledge to themes such as sustainability, energy and health.

Generations of Leiden students and academics have done archaeological research into the early medieval history of Oegstgeest. This makes this old settlement one of the best-documented sites from that era. In a new book, Leiden researchers take stock.

In this project, we will study the genetic and environmental drivers of woodiness and stem lignification at the level of plant‐to‐gene‐to‐molecule.

We would like to present to you a simple guidebook about living a sustainable life as a student in the cities of Leiden and The Hague. Whether you are a first-year student still trying to find your way around or already doing your masters – students wanting to explore more sustainable options and save…

Testing chemical substances without using animals. It seems a utopia, but a European team is going to develop a way to make this a reality. The RISK-HUNT3R project, led by Leiden professor Bob van de Water, received 23 million euros from the European Commission for this purpose. The project was launched…

The authors in this volume explore how external innovations (products, technologies, services, institutions and processes) have been appropriated in African societies in order to be acceptable and relevant to local conditions, expectations and demands.

Astrophysicist Ewine van Dishoeck has been awarded an honorary doctorate from the University of Geneva. She received the award on 11 October during the Dies academicus of the Swiss university, which, like Leiden University, is part of the European research university federation LERU.

Making public space more sustainable is considered very important in this project. The Humanities Campus will become a pleasant place to spend time, with lots of greenery. Here, people can relax and find coolness on hot summer days.

Twenty years from now, the world population is estimated to be around 9 billion people (now 8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this population will result in an enormous increase in the demand for food, consumables, water…

Roll your sustainable sleeves! Our students and staff have found various ways to do just that, both at home and at our university.

Lecture

On 17 October 2019, the Netherlands’ Ministry of Infrastructure and Water Management organised a first stakeholders meeting on microfibers from textile in the LEF Future Center. The meeting was prompted by a report of the National Institute for Public Health and the Environment (RIVM) in April of this…

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.…

Research at the Catalysis and Surface Chemistry group is comprised of the following research themes:

Many metalloenzymes that are key to bioenergetics are membrane enzymes, with canonical examples the complexes I, II, III and IV in the mitochondrial inner membrane. To study these enzymes in a native-like lipid membrane environment, we aim to develop novel bioelectrochemical techniques.

Learning from nature and utilizing microbial biodiversity to identify and characterize enzymes for degradation and upcycling of plastics and other polymeric materials.

Urban, Food, Water, Biodiversity, Resources and Energy: these are the main research topics of the Institute of Environmental Sciences. We always strive to be a global leader in our field. And make a real impact with both our research programmes.

The Institute of Public Administration studies the complex problems facing the public sector in the 21st century, from climate policy to the effects of digitalisation. Its researchers analyse, explain and help come up with solutions to the challenges of society today.

Graphene floating on water does not repel water, as many researchers believe, but rather attracts it. This has been demonstrated by chemists Liubov Belyaeva and Pauline van Deursen and their supervisor Grégory F. Schneider. Publication in Advanced Materials.

Plant Sciences' contribution to the Bioactive Molecules research theme is to identify new plant bioactive molecules, and unravel their mechanisms of action in plant development or health, and the regulatory networks and (bio)synthetic pathways required for their production.

Food waste is a defining inefficiency of the modern food system, with profound implications for resource use, climate change, and circular economy transitions. This dissertation examines food waste through two complementary lenses: the prevention of avoidable food waste and the valorization of unavoidable…

In Indigenous Ancestors and Healing Landscapes Jana Pešoutová presents new interpretations of current healing practices in Cuba and the Dominican Republic juxtaposed against the European colonization of the Caribbean after 1492.

The main aim of this thesis was to unravel the signaling and regulatory networks that drive tumor cell migration during breast cancer metastasis.

The mechanism of the electrochemical reduction of dioxygen by a mononuclear pyridylalkylamine copper complex was investigated (see picture). It was shown that in neutral aqueous solution dioxygen undergoes stepwise reduction, wherein hydrogen peroxide plays a key role. The rate constants determined…

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

Cardiovascular diseases (CVDs) are the leading global cause of mortality. Endothelial dysfunction, an early reversible stage of CVD development, is marked by decreased nitric oxide production linked to Ca2+ influx in endothelial cells.

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.
