How did people in the latter part of the Late Bronze Age organize themselves in order to be able to erect massive structures such as tholos tombs, citadels and how did they interact with these materials and circumstances while constructing? What impact did such a changing landscape have on their day-to-day…

the production, use and exchange of bodily accoutrements through the lenses of the microscope

Quantum computers deserve their own quantum internet. This is a network that dispatches information not in the form of bits - ones and zeros - but rather as qubits, just like in the quantum computer itself. In the view of Dirk Bouwmeester, a professor in Leiden’s Quantum Matter & Optics research group,…

At the Faculty's opening of the 2019-2020 academic year, the focus lay not just on the vision for the future of the social sciences, and the opening of the refurbished library, but above all on the government's plans for university financing. The speeches included an interview between Annemarie Samuels…

The master’s specialisation Cosmology at Leiden University is positioned at the interface between Theoretical Physics and Observational Astronomy. The main elements are theory, data analysis and numerical simulations, with research on the origin of dark matter as one of the highlights.

To deliver a Virtual Sensor tool optimised to exploit the synergy between Sentinels 2 and 3 to allow the consistent retrieval of land surface parameters (Albedo, LAI, and LST); To extend the existing capabilities of land EO data assimilation tools to add capacity to handle data in the thermal domain…

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

Tuberculosis is an infectious disease which is spreaded through the air. It is caused by Mycobacterium tuberculosis and it led 1.7 million people to death in 2016. This mortarlity rate is concentrated in developing countries such as Indonesia, Philippines, Pakistan, and South Africa. These numbers make…

The ReCiPe methodology for Life Cycle Impact Assessment (LCIA).

The current hepatitis B vaccines need to be stored and transported under refrigerated conditions (2-8 degrees C). This dependence on a cold-chain is highly challenging in areas where hepatitis B virus infections are endemic.

Accumulation of metals in economy and environment and its associated risks, within the Netherlands and the EU.

How can and should tasks and competences for the purpose of the criminal justice system (i.e. legislation, enforcement, the administration of justice and sentencing) be defined and formulated, while at the same time taking into account the chain concept, adjoining national and international legal domains…

How to access the end-of-supply risk of spare pares using big data analytics

CERA (CErtification of RAw Materials) is a four-year project that will develop a standardized certification scheme ensuring environmental, social and economic sustainability in extraction, processing, trading and manufacturing of all mineral raw materials. It will guarantee traceability of certified…

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

Developing methodes to understand the evolution of patches in natural ecosystems

Rare-earth materials are prime candidates for storing quantum information, because the undesirable interaction with their environment is extremely weak. Consequently however, this lack of interaction implies a very small response to light, making it hard to read and write data. Leiden physicists have…

Which traits and/or trade-offs determine benefits of being deciduous or evergreen?

The first photo of a black hole and measuring anxiety in the brain... From 13 until 22 May we're serving a free slice of science with your pizza.

Is scientific research useful? In his dissertation, Jorrit Smit argues that in order to answer this question one should not look at, for example, prominent scholars or influential organisations, but at places where knowledge exchange and co-creation take place. Promotion 6 May.

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

Leiden-Delft-Erasmus Universities will celebrate its tenth anniversary in 2022. In recent years, the alliance has expanded to include centres and new programmes as well as a curriculum of its own. What do the next ten years have in store?

Central elements in the research activities of all programme group members are: attachment, sensitive caregiving, and prevention and intervention.

This page features an overview of relevant lectures, publications and conference papers.

Leiden-Yale collaboration uncovers a tale of samurai same-sex love in a library manuscript.

This dissertation investigates the grammar of Makhuwa-Enahara, a Bantu language spoken in the north of Mozambique. The information structure is an influential factor in this language, determining the word order and the use of special conjugations known as conjoint and disjoint verb forms.

The euro crisis of 2010 has shown that the Eurozone lacks economic cohesion and that EU fiscal integration is needed for a stable euro. But can this integration exist without clashing with the national constitutional interests of the Member States? Frederik Behre looked into this matter in his PhD-thesis…

The Member States of the European Union do not intervene when a Member State disrespects the values of the European Union, Judith Sargentini, member of the GroenLinks party at the European Parliament, said at the annual Europa Lecture on 9 May in the Lorentzzaal of the KOG Building.

The documentary invites us to consider the question of what we consider valuable knowledge. “We need to realise that doing and thinking are intertwined in ways we did not comprehend before” argues Maikel Kuijpers, archaeologist and the producer of the documentary. “This will have consequences for the…

La Grande Roche is one of the rare archaeological sites that preserved a long sequence of deposits formed at the time of contact between late Neandertals and early Homo sapiens.

This thesis consists of three chapters, the first two of which concern division points of elements of the multiplicative group of a number field.

In Humanity’s End As A New Beginning, Emeritus Professor Mineke Schipper reflects on myths about ‘the end’.

To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

Generally the data from remote sensing surveys - the scanning of the earth by satellite or aircraft in order to obtain information about it - is screened manually in archaeology. However, constant monitoring of the earth's surface causes a huge influx of data of high complexity and high quality. To…

The Old Observatory of Leiden is the oldest extant university observatory in the world. While students of Leiden University receive lectures in the main part of the building, the visitor center in the basement and the telescopes on the building serve the general public.
