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)…

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

Drug-induced liver injury (DILI) is one of the main reasons for drug attrition during pre-clinical and clinical phases of drug development as well as for drug withdrawal post-marketing.

Barrier function is the natural role of the skin. The lipid matrix present in the outermost layer of the skin, the stratum corneum is important for this function.

Drug induced organ toxicity is the main problem of the drug development and drug usage in the clinic. The liver and kidneys are the most sensitive organs towards drug induced toxicity.

Animal Sciences’ contributions to the Biodiversity & Evolution 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.

How do commissions of inquiry operating in conflict situations utilize international law, and how can inquiry findings be utilized by other bodies belonging to the international legal community?

SRON Netherlands Institute for Space Research is moving. The headquarters of the institute will relocate to the Science Campus of Leiden University. In October 2019, the first pile was officially put into the ground; in 2021, the building will be ready for use. A first glimpse at the building that will…

A consortium of international researchers comes with a unique solution to the energy problem. By mimicking photosynthesis, they aim to produce sustainable fuels out of sunlight, water, and CO2. Their secret? ‘Soap bubbles’, says Leiden chemist Sylvestre Bonnet, who is part of the consortium.

With the Liveable Communities – Liveable Planet project, Marja Spierenburg, Professor of Anthropology of Sustainability and Livelihood, is showing that scientists are driven by ambition, hope and faith. She is linking Vrouw Vennepolder, a polder in Zuid-Holland, to the UN climate goals.

Through various initiatives, Leiden University is trying to make people aware of the importance of biodiversity: the cultivation of a wide variety of micro-organisms, animals and plant species. This is important because in the Netherlands biodiversity has declined from about 40 percent in 1900 to about…

From recurrent oil disasters to the outbreak of contagious diseases or major fires. Public organisations often learn too little from such crises, according to public administration specialist Wout Broekema. Staff frequently fail to communicate information adequately, which means that lessons are often…

Soil ecologists Emilia Hannula (Leiden) and Elly Morriën (UvA) received the Golden Medal of Teylers Tweede Genootschap on 5 November. They received the prize for their submission to a competition on sustainable soil management.

The WARN project seeks to understand why certain warnings fail to reach and impact decision makers in time to avert crisis.

How to take ownership of your career? To find out, students from ‘Design Your Career as a Climate Change Maker’ visited a farmer who has done just that. They learned from him that it’s never too late to start working on something you believe in.

Even as a child, Jan Willem Erisman wanted to make things better. As a professor Environmental sustainability, he is therefore also very active outside the university. He is known as the nitrogen professor: in the media all the way to the House of Representatives, he explains the nitrogen problem. Recently,…

An endless stream of publications, data and software accessible to all? Professor of Science Studies Thed van Leeuwen calls for a more human-centred approach and an overhaul of the PhD system.

The International Institute of Air and Space Law was delighted to host the 14th edition of the Leiden-Sarin International Air Law Moot Court Competition – for the first time – in Leiden! After three years of online mooting owing to the pandemic, this year’s competition was held again in person.

Marc Koper, Professor of Catalysis and Surface Chemistry, has been elected as President Elect of the International Society of Electrochemistry (ISE). He will be President Elect for two years starting January 2019, followed by two years as President and two years as Immediate Past President.

Kidney failure is a serious issue because kidneys cannot regenerate themselves after injury. A possible solution consists of artificially growing healthy kidney tissue. To achieve that, scientists first need to understand kidney development during the earliest stages, in the fetus. Leiden researchers…

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.

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…
