Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

Everyone knows smoking is unhealthy, but did you also know that smoking is not good for the environment? In parternship with UFB, we are organising a number of action days to pick up cigarette butts, hand out sustainable ashtrays and inform people about how they can smoke more sustainably!

How can we track biodiversity loss at the speed and scale needed to protect our ecosystems? The eDNA Citizen Science project combines cutting-edge environmental DNA technology with citizen science to enable residents, community groups, and local organizations to monitor aquatic and terrestrial biodiversity…

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…

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.

In the Schouwburgstraat, LUGO is currently redesigning the back-garden in order to increase biodiversity and make it a more beautiful space. Throughout October 2023 until March 2024, we will be making changes to the garden with our team of volunteers.

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

The team consists of

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

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

A seven-metre glass tunnel, filled with running water, and equipped with speakers and cameras. An artificial river for investigating what light and sound pollution do to migrating fish.

Beneficial plant-associated microbiota, particularly those inhabiting the rhizosphere, contribute substantially to plant health through pathogen suppression, stimulation of plant defence responses, and enhanced nutrient acquisition.

Are you eager to dive into a cutting-edge approach to innovation? Do you want to explore how frugality and frugal innovation can drive sustainability? And are you up for an international, real-life challenge? If so, this Leiden-Delft-Erasmus (LDE) minor on frugal innovation is for you!

The research described in this thesis focused on identifying novel drug targets and synergistic combinations for triple-negative breast cancer (TNBC), a virulent subtype of breast cancer with a dismal prognosis and limited therapeutic options.

This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

The main goal of the THEOR CHEM group, headed by Prof. Geert-Jan Kroes, is to characterize, and to accurately predict the outcome of chemical reactions at gas-solid and liquid-solid interfaces. Here the solid surface is typically a metal or an ice surface. These goals are important to many areas in…

Emperor Naruhito and King Willem-Alexander will visit Leiden University on Thursday 18 June.

Although there is considerable evidence that nature in the city is beneficial to both people and animals, we still do not have an overall picture of those benefits. To rectify that, a Leiden PhD candidate and a student – armed with a cargo bike – are using The Hague as a life-size laboratory.

This project uses archaeological, literary and epigraphic evidence to investigate urban development in Roman-period North Africa, compiling this in a GIS-linked database in order to analyse the development of urban settlement spatially over time.

On the basis of the characteristic aspects of a picture, certain computers can tell us what the picture is showing. They can learn this in the same way that young children are able to learn to recognize images. Further improving these techniques opens the way to a whole range of new applications. Biology…

The researchers in the World Archaeology department of the Faculty of Archaeology concentrate on a range of different periods and regions: from humanity’s origins to the Middle Ages and the modern age, and from Asia to South America.

The Food citizens? team has included two post-docs, three Ph.D. candidates and two research assistants working with the Principal Investigator. The Winter School involved nine Masters and Ph.D. candidates from the universities of Bologna, Gothenburg, Kaunas, Leiden, Louvain, Tromsø, Turin and Utrech…

Between foraging and farming: an extended broad spectrum of papers presented to Leendert Louwe Kooijmans.

NL-BioImaging AM is a distributed research infrastructure aimed at promoting progress in the most cutting edge microscopy technologies and providing open access to these technologies to a broad community of academic and industrial users. All Netherlands bio(medical) microscopy centers participate.

Update : August 2017 Dr Willem van Haarlem

On the basis of the characteristic aspects of a picture, certain computers can tell us what the picture is showing. They can learn this in the same way that young children are able to learn to recognize images. Further improving these techniques opens the way to a whole range of new applications. Biology…

How were the Russians, under early modern conditions, able to incorporate this distant, undeveloped and, because frequent nomadic attacks, dangerous territory? And what role did the Kolyvan-Voskresensk plants play in this process?

Leiden University’s new ‘Europe Hub’ is an interdisciplinary platform that showcases the university’s research and teaching expertise and capacities on Europe’s societal and governance challenges.

If you follow the western media, you are likely to think of ‘Africa’ as the continent of origin of desperate migrants, a continent of hunger and disease and a breeding ground for international terrorism. But if you want to see the bigger picture, you should look no further than the African Studies scholars…

The collaboration between ISGA and the NIPV (Netherlands Institute for Public Safety) has been made official. This took place under the guidance of initiators Jeroen Wolbers (ISGA) and Peter Bos (NIPV) during the conclusion of the three-part lecture series on the Dutch crisis management system. Sanneke…
