Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

Although migration and integration have become important concepts today as a result of globalization, migration movements, integration, and multiculturalism have always been part of the history of Europe. Few people realize how many ethnic groups participated in migration within Europe or into Europe…

Sonorous phenomena are always on the verge of becoming something else. As it unfolds, sound constitutes spaces, mediates presence, articulates time. Furthermore, it may prompt emotions, generate awareness, organise patterns of behaviour or trigger a sense of belonging. As sound becomes audible, it is…

PhD candidate Agnes van Steen researched the history of the Leiden women’s rights movement (1860-1990) and found that the university produced many feminists.

In the past 30 years, over 5,000 planets have been discovered outside our solar system. One common exoplanet is the lava world, a hot super-Earth with oceans of liquid lava. Mantas Zilinskas developed models to simulate possible atmospheres of these. Those simulations provide guidance for astronomers…

The present market regulations make it extremely risky to invest in green energy, and this is impeding the fight against climate change. This is what Oscar Kraan writes in his dissertation. PhD defence on 25 April.

As Director-General of the ESO for the past ten years, Leiden University astronomer Tim de Zeeuw had ‘the best astronomy job in the world’. Back at the Leiden Observatory, he is focusing on the first 3D map of the Milky Way.

An international team of astronomers, including astronomers from Leiden University, has found the missing link in the path taken by water through star-forming clouds and young stars to comets and planets. They did so with the help of the ALMA observatory in Chile. The researchers published their findings…

Three Leiden astronomers have shown that some asteroids that are considered harmless for now, can collide with Earth in the future. They did their research with the help of an artificial neural network. The results have been accepted for publication in the journal Astronomy & Astrophysics.

The European Research Council has awarded an Advanced Grant to Prof. dr. Maarten E.R.G.N. Jansen for the research project

Just like us, plants also produce growth hormones, and they also go through an ageing process. The study of the genes and mechanisms behind these processes is useful not only for crop breeding and agriculture, but also for medical research. That is the view held by Professor of Plant Developmental Genetics…

The ALMA Local Expertise Group (Allegro) is located in the Leiden Observatory (Sterrewacht). Professor Ewine van Dishoeck: ‘The Netherlands has played an important role in establishing ALMA. Thanks to this subsidy, we can now reap the scientific benefits.'

On 4 March, KPN published the seventh edition of the European Cyber Security Perspectives. Els De Busser and Tommy van Steen, both Assistant Professors at the Institute of Security and Global Affairs, have contributed an article on interdisciplinarity.

ISGA researchers have received €1 million for research aimed at enhancing the Netherlands' digital resilience. The funding comes primarily from NWO, but private parties are also contributing financially. In total, €10.5 million is being allocated to launch six projects.

LIACS aims at being a diverse and inclusive research institute. To reach this goal, two instances are working on addressing diversity related issues.

Astronomers have used data from the European Gaia Space Telescope to discover 55 high-speed stars launched from the young star cluster R136 in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. This increases tenfold the number of known “runaway stars” in this region. The team of astronomers,…

As early as 2030, batteries in electric vehicles could fully meet the need for short-term electricity storage around the world. By connecting them to the power grid they can provide their stored energy, improving energy security and enabling renewable technologies in cleaning the grid.

Leiden PhD student Xuequan Zhou has designed a new promising molecule that efficiently kills cancer cells, but does not harm healthy tissue. The trick: the drug is only active when irradiated with light. Zhou’s new compound does this extra efficiently by cleverly self-organising into nanoparticles.…

Seagrass is a marine flowering plant with special adaptations to coastal and marine environments, playing a crucial role in providing a wide range of ecosystem services.

No more lectures and exams for the Radio Astronomy course taught by Michiel Brentjens. The corona crisis is a moment of reflection that has changed his whole way of teaching. Instead of being in front of the class, he lets his students build a radio telescope with paint cans.

After nearly 70 years, the Leiden Observatory has a new telescope. A crowdfunding action in March brought in the 20,000 euros required to build a solar telescope. On 19 September Rector Magnificus Carel Stolker officiated at the opening.

The housing crisis is affecting a substantial group of Dutch citizens and is one of the main election themes this year. How did things get this far and what should the new cabinet do in the coming four years to address the problems? Three Leiden researchers give their answer.

On Monday 9 May Mercury will pass between the Earth and the Sun. This rare event can be followed in the Leiden Observatory. The Observatory's new solar telescope produces a very clear image and offers a unique opportunity to observe Mercury at the highest magnification possible in the Netherlands.

Galaxies are often found in clusters, which contain many “red and dead” members that stopped forming stars in the distant past. Now, an international team of astronomers, led by Andra Stroe of Leiden Observatory and David Sobral of Leiden and the University of Lisbon, has discovered that these comatose…

Her specialist field is molecular astrophysics, and she is the most quoted scholar in her field. In this, the year of astronomy, she is the ideal person to give the Dies lecture at the university with the world's oldest astronomy institute; it goes without saying that the lecture will be on the newest…

On 24 November 2022, Simone van der Hof delivered the annual Mulock Houwer Lecture. The title of the lecture was ‘Niet om de knikkers maar om het spel – Over de digitale versie van een vergeten kinderrecht’.

For one year, seven young anthropologists were appointed as Stadsfotograaf Leiden. They published on a weekly basis photo-series on daily life in and around Leiden in the local newspaper. A selection of these photographs is currently on display in a pop-up exhibition! Come by on 28-29 September at Papengracht…

Knowledge and culture subproject 4:

Leiden is the ideal city for students. There is a wide variety of activities you can do next to your studies, to make the most out of your student life.

Leiden University provides ambitious students with the most recent and innovative areas of knowledge, and offers them the freedom to develop their own area of expertise.

The long term goal of the Biophysical Organic Chemistry/SSNMR group, headed by Prof. Huub de Groot, is to reach an understanding of structure, dynamics and functional mechanisms of membrane proteins and self-organized biological assemblies and to translate this knowledge into new concepts for nano-devices,…
