‘We could share our knowledge more with others and apply it more widely,’ said Annetje Ottow, President of the Executive Board, while presenting the new Strategic Plan on the University’s 447th Dies Natalis. The new Strategic Plan therefore focuses on innovating and connecting, among disciplines and…

Not only dark matter, but also ordinary matter and dark energy are tracked in the largest ever cosmological computer simulation ever. In the FLAMINGO simulations, you can see virtual galaxies and clusters of galaxies emerging over the course of billions of years. This is no easy task: with more than…

A dissertation covered in hot pink faux fur, antique prints of PhD ceremonies, a pot encrusted with sealing wax: the Hora est! anniversary exhibition at Oude UB takes you to the ritual yet idiosyncratic world of PhD ceremonies.

The 'deepest and sharpest' image of the Universe to date: the first photos from the new James Webb space telescope yesterday mesmerised astronomers and the public alike. Leiden Professor of Molecular Astrophysics, Ewine van Dishoeck, spoke to various media outlets about the first images, which include…

Various Leiden researchers have been awarded a European grant to explore the commercial or societal potential of previous research.

High-quality education, research involving multiple faculties, collaboration between universities and central government funding to make all this possible: these were the topics covered in a working visit of the Standing Committee for Education, Culture and Science (OCW) to the Association of Universities…

Finally we know for sure that there is a black hole at the centre of our own galaxy. Today, astronomers unveiled the first ever photo of Sagittarius A*, a super-massive object at the centre of the Milky Way. This picture could only be taken thanks to the cooperation of telescopes worldwide.

Galaxies in the early universe contain more dust and hidden star formation than previously thought. That's what Ivana van Leeuwen concludes in her PhD research, where she combines data from various telescopes to create a more complete picture.

Planets existing in other solar systems contain invaluable information about the origin of planets and life. PhD candidate Yapeng Zhang has studied their atmospheres by looking at their smallest parts: isotopes. With her research she hopes to discover what makes our own solar system unique.

After many years of preparations, CERN has approved a groundbreaking new experiment: the Search for Hidden Particles (SHiP). Physicist Alexey Boyarsky was involved from the start. ‘We know there is physics that’s missing and we aim to find it.’

A CT scanner to treat eye cancer, energy-efficient software for the future and a test to identify male chick eggs. Three projects by researchers from Leiden University are to receive funding from research funder NWO’s Open Technology programme, to which the business sector also contributes.

With his clever measuring methods Ignas Snellen – together with his team – was the first to detect carbon monoxide in the atmosphere of exoplanets. For his pioneering work the Leiden astrophysicist has been awarded the Spinoza Prize, the highest academic honour in the Netherlands. The prize of 2.5 million…

When you think of a library, you probably picture books – or students quietly studying. But for subject librarian Rutger de Jong, most of the work happens online. ‘We never throw anything away. Everything produced here in the name of science should remain findable.’

Conference

The Dutch universities as a whole are lobbying for a 'normal' academic year from the end of August, where on-campus teaching will be possible. It's a view that Leiden University shares. Rector Hester Bijl talks about what teaching will be like then. She also looks back on a year of lockdown.

Over the centuries painters and photographers have depicted students at study in Leiden. An exhibition at the Hortus botanicus reveals the similarities and differences in 450 years of student life.

Research on quantum computers and Islamic charities: two Leiden researchers have received a Consolidator Grant from the European Research Council.

Despite an eventful afternoon – with Students for Palestine occupying the Academy Building – political scientist Hélène Landemore gave her Cleveringa Lecture as planned on 26 November. She reflected on the protest and the importance of open debate, within the university and within a democracy.

Education

Goldband, Skrillex, Róisín Murphy and... quantum: the latter may not be a band but is part of the Lowlands line-up nonetheless. Scientists from Leiden University are using the festival for research on the very smallest particles.

From memorials to the armed forces to memory stones for individual victims. It was only later that the Holocaust took a central role in Western remembrance culture, Cleveringa Professor Frank van Vree notes. ‘Nationalists and human rights activists both invoke the experience of the Holocaust.’

How are supermassive black holes born? That is the question astronomer Elena Maria Rossi is trying to answer. But how do you investigate something you cannot see?

Wolves in the Netherlands mainly feed on wild animals such as wild boar and red and roe deer. But in areas such as Drenthe where these are scarce they also prey on free-roaming cattle used for nature conservation

Almost 81 years after his famous protest speech against the German occupation, Leiden professor Rudolph Pabus Cleveringa will be remembered in his Groningen birthplace of Appingedam. A statue of him will be unveiled there on 12 November amid various other activities.

In a sailboat, a canoe or stowed away on a ship: during the Second World War, many Leiden students tried to cross the sea to join the Allies in Britain. ‘Soldier of Orange’ is the most famous, but who were the other ‘England voyagers’ or Engelandvaarders as they are known?

During the ‘Hour of Remembrance’ on 4 May, the University community remembers its students and staff who were killed in the Second World War. It also looks at freedom and oppression today. Three questions for Sara Polak, chair of the Hour of Remembrance committee.

Our banking, DigiD and sensitive medical data: what if our entire digital infrastructure can no longer be trusted? Jelle Don has this question permanently in mind as he goes about his research. And that is no bad thing because without new digital security measures, our society will be extremely vuln…

With its Green Deal The European Union has set itself much-needed ambitious climate goals. But the energy crisis and geopolitical tensions are making these difficult to achieve. Seven researchers from the Leiden-Delft-Erasmus Universities (LDE) alliance have written a white paper offering solutions.

The year 2023 saw the earthquake in Turkey and Syria, the Wagner Group rebellion and wildfires and floods as all the weather records were smashed. Our most-read stories were about the climate crisis and the elections: here’s the list.

If you'll soon be getting a COVID-19 vaccine, you might just get the Johnson & Johnson (Janssen) one. This vaccine was developed for the most part in Leiden – and this is no coincidence. Watch the animation below about the development of one of the vaccines in the fight against COVID-19.

There are more molecules that could conceivably be candidate drugs than there are stars in the universe. How can we ever efficiently identify those molecules? Professor of AI and Medicinal Chemistry, Gerard van Westen: ‘I’m going to use artificial intelligence as the co-pilot to make an automated search.’…

From 14 to 29 PhD candidates, seven actively involved faculties and, above all, lots of innovative interdisciplinary research, all with data science as the common denominator. The university’s Data Science Research Programme (DSO) has proven so successful that after five years on a start-up grant it…

Students and staff from Leiden University are protesting in The Hague on 25 November against the billions in cuts to higher education. ‘The cuts are a terrible idea and we want to show why’, says Claire Weeda from WOinActie. ‘Research and teaching are essential to society.’
