Planets are formed in disks of gas and dust around young stars.

The effectiveness of the skin barrier underlies the outer layer of the skin: the stratum corneum (SC). However, in several skin diseases this barrier is impaired. In two inflammatory skin diseases, atopic eczema and Netherton syndrome, an increased level of monounsaturated fatty acids (MUFAs) has been…

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…

This dissertation explores various perspectives on the term immersion, and its relation with, and transformation through, a composer’s practice.

The department of World Archaeology combines research and education about regions all over the world, from Human Origins to the Middle Ages, and from Europe, to Asia, Africa and the America’s. That broad range in time and space makes the department a dynamic pluriform community with many different approaches,…

Just as in phase 1, phase 2 of the Gorlaeus Building will focus on sustainable building.

High resolution altitude data created by airborne LiDAR allow the investigation of large areas and often inaccessible tracts of land and has the potential to reveal undiscovered archaeological heritage.

Archaeological heritage management is concerned with the identification, protection, management and preservation of the material remains of human activity in the past (of whatever period and in whichever region of the world) and with the interaction that this involves with all kinds of stakeholders.

The occupation of the Afghan capital Kabul by the radical Taliban movement on 15 August 2021 received enormous international attention, not least because of the crisis that soon enveloped Kabul airport as desperate Afghans sought to flee the country on evacuation flights mounted by the United States…

A radical reduction in the amount of meat, dairy and other products sourced from animals is possible in the coming decades, as people turn to an increasing variety of alternatives. This would unlock vast amounts of land that we could use to produce energy and remove carbon from the atmosphere. Leiden…

Following the Beirut explosion, BBC's podcast series The Foodchain explores the chemical that caused the blast: ammonium nitrate. A compound that is widely used to produce fertilizer. Professor of Environmental sustaibability Jan Willem Erisman tells about the effects of nitrogen on the environment.

Leiden’s beadle, Willem van Beelen, is retiring on 29 February. How does he look back on his career and what do those in the know have to say about him?

In Leiden University's Vision on Sustainability 2030, biodiversity (biological diversity) is an important focus in its teaching and research and on its campuses.

The latest research from the Leiden outdoor laboratory ‘Living Lab’ shows that the insecticide thiacloprid strongly influences even the most common and robust dragonfly species in the Netherlands. The study was published in the Journal of Applied Ecology.

The sustainable production of hydrogen could potentially be made more efficient by adding a cleverly chosen salt to the process. Researchers at the Leiden Institute of Chemistry (LIC), in collaboration with physicists at the University of Twente, have discovered that the type of salt present in the…

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…

In the research programme Drug Discovery & Safety, we are interested in the efficacy and safety of new drugs and novel means to decipher these aspects. Hence, we employ advanced imaging and high-throughput screening techniques next to computational approaches such as chem- and bioinformatics.

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

Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…

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).

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.

The barrier function of the skin is primarily provided by the stratum corneum (SC), the outermost layer of the skin. Skin barrier impairment is thought to be a primary factor in the pathogenesis of atopic eczema (AE).

Through extensive archaeological and documentary research, this study aims to provide a detailed analysis of the maritime cultural landscape of St. Eustatius over the past four centuries. It focuses on bridging the gap between the marine and terrestrial worlds and demonstrates that in order to truly…

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!

The Great Rift Valley in Africa is a real treasure trove for discovering early human fossils. The fossils found in this part of Africa have determined our view of human evolution. But was the Great Rift Valley really the place where evolution took place or just a place where fossils are well preserved…
