The Institute of Criminal Law and Criminology conducts extensive research on imprisonment. Sending a person to prison is the most severe form of punishment that can be applied in the criminal justice systems of European countries. In most countries, the number of prisoners has risen in recent decades.…

Hydrogen peroxide (H2O2) is an important bulk chemical that is used in various industrial processes. More than 95% of the H2O2 used in industry is made via the anthraquinone process during which a large amount of energy is going to waste.

How to stimulate novel research in science and innovation

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).

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.

Inspiring and relaxed – these are qualities that describe the Netherlands perfectly. At the same time, there is much more to say about the country. For instance, according to the 2018 UN Human Development Index, the Netherlands is ranked tenth among the best countries to live in.

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…

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.

Sprayable plant-based adhesives for crop protection against thrips Some plants, such as sundew and tomato, protect themselves with sticky hairs that repel or even trap arthropod herbivores.

When migrating from China to Siberia, a few intermediary food stops are not a luxury. For migratory birds, they are even crucial for their survival. However, climate change is altering the seasonal availability of food at these stops. Environmental scientist Yali Si has discovered that because of this,…

The "Van Marum Colloquia" are a collaborative lecture series between the LION and LIC institutes, focusing on fundamental and applied surface science.

A wide range of metals need to be mined for solar panels, wind turbines and batteries. But the overall mining activity is set to decrease as clean energy replaces fossil fuels such as oil, coal and gas.

Extremely painful chronic cluster headaches – sometimes referred to as ‘suicide headaches’ – can be prevented by stimulating the occipital nerve in the back of the head, according to research conducted by Professor Emeritus of Neurology Michel Ferrari from Leiden University Medical Center (LUMC). The…

‘It's empty talk, nothing but political posturing,’ says Prof. Leo Lucassen about Minister Lodewijk Asscher's plan for a participation contract for migrants. ‘It will never happen.’ Lucassen, Leiden specialist in History of Migration, discussed Asscher’s Integration Letter on the NTR programme De Halve…

Older children more frequently link Black Pete with a black person. Both younger and older children think positively about him. This is the conclusion of a study conducted by Judi Mesman, Professor of Diversity in Parenting and Development.

The new Erfgoed Gezocht/Heritage Quest website means you can play armchair detective and hunt for undiscovered burial mounds in the Veluwe. This will help stop them being destroyed by construction projects. The website is the initiative of the Leiden University Faculty of Archaeology in collaboration…

In 1925, two young physicists from Leiden University, George Uhlenbeck and Samuel Goudsmit, proposed a radical idea: spin. Their bold hypothesis quickly came to play a key role in physics and formed the basis for later breakthroughs in quantum mechanics. We are celebrating the anniversary of this discovery…

The new Humanities Hub in the Huizinga Building was officially opened on Tuesday 3 December. In the different labs, researchers presented the options for using digital technologies in humanities research.
