‘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…

Over hundreds of thousands of years, our region witnessed the comings and goings of various types of hominin. This depended on the temperature as ice ages alternated with warmer periods. In ‘De eerste mensen in de Lage Landen’ (‘The First Humans in the Low Countries’) Leiden archaeologists Yannick Raczynski-Henk…

The legal distinction between victims of human trafficking and victims of migrant smuggling is unjust, argues De Massol Rebetz in her PhD thesis. In certain instances, smuggled migrants should be treated the same as victims of human trafficking.

During adolescence, some young people have stable best-friend relationships, while others change best friends frequently. Developmental psychologist Lisa Schreuders has studied the brains of young adolescents: ‘It seems that friendships in your early years can have consequences for your friendships…

Leiden researchers have developed a groundbreaking model to advance cancer immunotherapy. Using a 3D printer, they create mini-tumors within an environment that closely mimics human tissue. They have also developed a method to monitor real-time interactions of these mini-tumours with immune cells during…

Inaugural lecture

Imagine no one in the Netherlands would eat animal products anymore, what would happen? And would it contribute to more climate justice? That is the theoretical exercise that environmental scientist Jan Willem Erisman and landscape architect Berno Strootman are taking up. 'Sometimes you have to think…

Alicia Schrikker doesn't usually get involved in urban history. As a senior lecturer, her research field is generally the colonial history of Asia and partly South Africa. So, the fact that she is going to carry out an urban history research project together with colleagues, is something that even she…

Adults who were abused or mistreated as a child and consequently suffer from post-traumatic stress disorder (PTSD) can benefit greatly from cognitive behavioural therapy. This is the conclusion of a study of 149 patients. Researcher and PhD candidate Chris Hoeboer is hopeful about the results and the…

They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.

Two Leiden University science communication projects have been awarded a WECOM grant through the Dutch Research Agenda (NWA). One project is a study of the history of the deaf community in the Netherlands and the other is of a condition that causes people to lose their way.

With the rise of AI, interest in computational linguistics and language models has taken flight. But machines are far from being able to go it alone. In her inaugural lecture, Professor Carole Tiberius will stress the importance of research on word combinations. ‘We know a great deal but there is a…

The English-language interdisciplinary minor ‘AI and Society’ explores the role of artificial intelligence in our society. The interdisciplinary nature of the minor is proving beneficiary for students and lecturers alike. We sit in during a class.

There were no bitcoins or artificial intelligence when our civil code was compiled. This could cause problems.

PhD defence

Organisations like the UN and the EU should be given more powers to combat transboundary problems. This is the message of a report published by the Swedish SNS Democracy Council, whose authors include Prof. Jan Aart Scholte of Leiden University. The researchers also wrote the following article.

Teens with depression appear to be more sensitive to criticism from their parents than their healthy peers are.

Wat gebeurt er op het schoolplein? Sensoren op kleding openbaren pijnlijke patronen

‘AI can’t do half as much as people think,’ says computer scientist and psychologist Roy de Kleijn. He tries to teach robots seemingly easy things, and keeps on discovering how smart human intelligence really is. Three things that computers are no way near doing.

Artificial intelligence can help doctors analyse images such as MRI scans. In future it may even be able to predict how a tumour will grow. And that is badly needed to relieve the pressure on healthcare workers.

The new Dutch government must act quickly to take rapid, far-reaching measures in three specific regions to tackle nitrogen emissions. This will create the space for a long-term strategy to deal with other urgent problems and the knot of obligations that the state will need to untangle. These are the…

Debate

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.

Ad IJzerman, Emeritus Professor of Pharmacochemistry, was made a Knight of the Order of the Lion of the Netherlands on 26 April. He was presented with the royal honour by Mayor Elbert Roest in the town hall in Bloemendaal.

A wind turbine near your home? The energy transition is not seen as just by all parties concerned. It’s essential to involve local residents, argues Emma ter Mors, social psychologist. As a researcher, she focuses on identifying factors that influence public acceptance of energy technologies. Isn't…

All over Europe you will find ethnographic museums with large collections of indigenous objects from Latin America. These collections shaped the image of native populations in the European mind. An ERC Starting Grant allows Dr Martin Berger to look at the bigger picture, contextualizing individual collections…

Video conferencing from your sitting room and algorithms on social media that know your interests: new technology is an increasingly integral part of our lives. At the same time there is a growing call to protect our privacy, and this is causing friction, at the University too. In part because of the…

Leiden University has joined the Hague Climate Agreement. This comprises 38 climate deals aimed at making The Hague climate neutral by 2030.

All five episodes of the first season of 'Breingeheim' are now available to listen on Spotify. The first season of the podcastseries is about the social contexts of adolescent development and how teens become resilient individuals. In every episode, a new Leiden-based behavioural scientist and an adolescent…

The theme of the Opening of the Academy Year on 4 September was sustainability and how the university could take the lead as a change agent. How is it going about this and what else can it do? There was also room for a critical note.

How do you make effective use of AI and medical technology? And what role do you play in this as a doctor? This is what the LUMC/Leiden University is preparing medical students for, right from the first year of their studies.

What does a 19th-century exhibition of traditional utensils from the province of Zeeland tell us about the current rise of populism? A lot, Ad Maas will say in his inaugural lecture.

The law and Artificial Intelligence (AI) applications need to be better aligned to ensure our personal data and privacy are protected. PhD candidate Andreas Häuselmann can see opportunities with AI, but dangers if this does not happen.

A fragmented political landscape, permanent pressure from current affairs and an increasingly political civil service: our government faces many challenges. This makes it all the more difficult to make important decisions about pensions or the climate. Research and good education can help meet the challenges…

Imagine scanning lion dung or a mouse dropping and instantly knowing exactly what and how much the animal has eaten. Thanks to new DNA techniques, this is becoming increasingly feasible. PhD student Kevin Groen tested how effective these techniques are at unraveling the diets of wild animals.
