The Lucia de Berk case or the suicide of Slobodan Praljak at the International Criminal Tribunal for the former Yugoslavia: certain trials keep popping up in media. In her dissertation, Tessa de Zeeuw examines the cultural appeal of such cases and analyses artistic responses. ‘Artworks sometimes have…

The successful PRINS (PRactising INternational Studies) project offers International Studies students an introduction to the world of practice. In the last semester of their bachelor’s programme, they work as consultants for real-life clients, ranging from Rabobank to Greenpeace. We took a look at the…

During her master's thesis, Nashanty Brunken (24) worked in a team with five other women. With this female team, they discovered the largest molecule so far identified in a disc. 'I have learned so much and because we are all women, it is incredibly empowering. It's very cool to see how far we've come…

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…

Writing a master’s thesis in Political Science is a demanding yet rewarding journey. Every year, students deliver impressive research that showcases their analytical skills and academic rigor. This year, one thesis stood out for its exceptional quality. On 31 October 2025, during the master’s graduation…

Predicting the collective behaviour of systems, like a large group of people electing one of the parties, is no easy task. But there’s a theory that scientists have been using for decades to do just that: the theory of Gibbs measures. Last week, mathematician Mirmukhsin Makhmudov earned his PhD for…

Hydrogen can help to solve the climate problem. At least, if we start producing it in the right, clean way. Leiden researchers mapped out the global environmental impact of hydrogen production and looked ahead to 2050. They published their work in Energy & Environmental Science.

How do you study the growth of microorganisms, the spread of epidemic diseases or the healing of wounds, without actually performing experiments? Daoyi Wang, PhD candidate at the Mathematical Institute, worked on a specific mathematical model that can describe the growth of microorganisms and many other…

While the Netherlands was in lockdown because of the coronavirus, PhD candidate Koen Rijpkema began his research into the same virus. In the lab, he developed molecules that can inhibit an important viral enzyme.

Want to find out how to assemble a human skeleton? Do you know what chemistry can be found around you? And are you easily fooled by fake news? Discover this and more at our Science Fair on 3 October.

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.

What makes young people susceptible to misinformation? And how do their friends influence this? Psychologist Jiemiao Chen aims to find out by using eye-tracking to monitor where young people focus their attention while watching TikTok videos.

Successfully completing a master’s thesis in Political Science is no small feat. Not only is this for most students the most extensive and in-depth research report they have ever written, the work is also held to very high standards. Yet, every year students manage to impress their instructors and demonstrate…

How wonderful would it be to use art, technology and science in Ukraine's recovery? Young Ukrainians currently residing in Poland get guidance to develop creative programmes and activities that can later be implemented. Leiden astronomers Pedro Russo and Kateryna Frantseva cooperate in the project.

Dutch politics has long been a paragon of stability. Think, for example, of our party system until, say, the last decade. At the same time, we also see occasional changes and significant shifts. Society has changed and this is reflected in, among other things, how we vote and how policy is made. About…

Not everything that comes close to a black hole is swallowed by it. Black holes can also hurl material away, and that chance turns out to be considerably bigger than previously thought. Martijn Oei's accidental discovery and his subsequent research on it earned him a cum laude promotion on 12 Decemb…

Many protoplanetary discs in which new planets are formed are much smaller than thought. Using the Atacama Large Millimeter/submillimeter Array (ALMA) scientists of the Leiden Observatory looked at 73 protoplanetary discs in the Lupus region.

Are magnetic fields older than the first light? And how did they influence the development of our universe right after the Big Bang? Cosmologists from Leiden, Groningen, and Utrecht are now collaborating to investigate this.

For the first time, an international group of astronomers have seen the heat glow of two ice giant planets colliding. They could also observe the resultant dust cloud move in front of the parent star several years later. Led by Leiden astronomer Matthew Kenworthy, they monitored the star's brightness…

After ten years and one day, Leiden Observatory has a new director. As of 1 September, Ignas Snellen will set the course for the astronomical institute. In this interview, you will get to know Ignas. Or at least a little. That is why we gave him five dilemmas and asked the people around him who he really…

While tens of thousands of visitors dance to deafening music, a team of Leiden psychologists are trying to collect data for their research at Lowlands. How do festivalgoers experience a virtual trip? And what role do factors such as too little sleep and whether they have experience with psychedelics…
