From 9 September onwards, Leiden scientists, citizens and farmers will jointly investigate how to sustainably manage peat meadowland. In ten years' time, they hope to have learned how to promote biodiversity and simultaneously reduce nitrogen and CO2 emissions, among other things. The research will…

Life returned to something resembling normal after Covid but other crises soon took its place. These great challenges are also being felt at the University and our researchers are working on solutions. The nitrogen crisis, problems with young people’s services and an increasingly urgent climate crisis:…

The battle for a strong power position in the run up to the provincial council elections in the Netherlands is currently being fought fiercely. Prime Minister Mark Rutte has become accustomed to a minority in the Senate in recent years. The four Rutte cabinets were always able to do business with various…

The fact that a significant number of seats in the Dutch provincial councils are now occupied by members of the Dutch Farmer-Citizen Movement (BoerBurgerBeweging, BBB) who have an agricultural background need not lead to conflicts of interest when voting on, for example, nitrogen emissions. This is…

We hebben 6 van de 9 grenzen overschreden die bepalen of menselijk leven in de komende generaties nog mogelijk is op aarde. Kunnen we het tij nog keren?

Almost a century passed since the much-celebrated judgement in the case concerning the Factory of Chorzów was delivered. This 1928 judgement of the Permanent Court of International Justice affirmed the essential principle of ‘reparation’ in international law, claiming that ‘restitution’ is the preferred…

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

The aim of the research project is to get insight in the biostratigraphical age and the palaeoecological setting of the Schöningen sites and hominin behavior and subsistence during the late Lower Palaeolithic.

How can wide-scale applications of isotope analyses and isotope mapping contribute to the identification of ancient migrants and their origins in the Western Caribbean? Can we observe linkages between individual behaviors and long-term patterns, for example as manifested in continuous waves of migration?…

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

The MORE project covers the development of the new entrance area for the Leiden Bio Science Park. Partners Leiden University, the Municipality of Leiden and the Amstelveen-based development agency Yisheng signed the agreement on 18 March, marking the official start of the project.

Just like every other organism on Earth, plants’ ultimate goal is to survive and reproduce. In order to achieve this, they must make trade-offs between where and how to allocate their finite set of resources. Whether they put their resources and energy into their growth, reproduction or maintenance,…

Plastic pollution is a major environmental issue. Although regulation is being adopted, plastic pollution is still increasing. Effective and strict enforcement is key and NGOs and civilians can be instrumental in this.

Interest group Animal Rights has started a test case to prompt the Netherlands Food and Consumer Product Safety Authority (NVWA) to tackle farmers who do not adequately protect their livestock against wolves.

Governance of Sustainability is a two-year programme, worth 120 European Credit Transfer System points (ECTS).

In otherwise energetic desserts at the bottom of the sea, researchers have found oases where microbes can harvest energy. Remarkably, the microbes first have to be buried under starving conditions for 80,000 years. An international group of researchers, amongst them José Mogollón from the Insitute of…

For the first time, international researchers have mapped the network of bacteria on coral reefs. They write about it in Nature Communications (9 April). Professor by special appointment Nicole de Voogd (Naturalis Biodiversity Center & Institute of Environmental Sciences) and two of her PhD students…

No more smelly lorries disposing of building waste or delivering building materials to the centre of Leiden.

The development plans for the Humanities Campus are changing somewhat. The financial challenges at the Faculty of Humanities and the higher education cuts mean Leiden University has to reduce its spending. One consequence is the Lipsius building will not be rebuilt after demolition in 2031.

The European Project SUNRISE, ‘Solar energy for a circular economy’, has been selected as one of the six Coordination and Support Actions (CSA) within the Horizon 2020 programme of the European Commission. Funded with 1 million euros, it will set the base for a large scale European research project.…

For many people spring is associated with the awakening of nature. The trees begin to paint the backdrop green again, welcoming the beginning of a new season with the chorus of frogs and bees, and the scent of flowers in the air. For Jaqueline Henrot, researcher at Naturalis Biodiversity Center and…

Dutch talkshow ‘Vier Avonden op Rij’ focused on the fall of the Schoof Cabinet, caused by PVV leader Geert Wilders withdrawing from the coalition. Wim Voermans, Professor of Constitutional Law, called the fall of the cabinet 'dramatic'.

In his report, Dutch cabinet negotiator Kim Putters proposes the formation of a ‘programme cabinet’ and an outline agreement. The four political parties involved have agreed on this form of cabinet, and Putters therefore appears to have succeeded in his mission. Wim Voermans, Professor of Constitutional…

In 2015, Jorryt Matthee thought he discovered an extremely distant galaxy called CR7, which lacked elements heavier than helium. Three years later, he shows with measurements using the ALMA telescope that the galaxy does have carbon after all, and even in normal concentrations. The American Astronomical…

Jan Zaanen, Professor in Theoretical Physics of condensed material, has been awarded a Spinoza prize. His pioneering ideas about the collective behaviour of quantum particles and high temperature superconductivity have often given him the reputation of being something of a rebel.

Overview of all dissertations published by PhD candidates from CML.

What are the patterns and processes of human mobility in the pre-colonial circum-Caribbean as revealed by burial populations and what are the underlying motives and socio-cultural principles on both micro- and macro-scales?

We investigate the processes underlying the patterns. We aim to explain biodiversity by investigating the distribution, function, development, and evolution of body forms, as well as physiological and behavioural variety among species. We collaborate with those specialized in describing, archiving,…
