An international team of astronomers led by Ardjan Sturm of the Observatory has made the first two-dimensional inventory of ice in a planet-forming disk of dust and gas surrounding a young star. The researches, including Melissa McClure, used the James Webb Space Telescope and publish their findings…

Early diagnosis, new treatments, and personalised care: all of these are possible if we can better unlock the wealth of information hidden in health data. Unfortunately, this data is often poorly organised, difficult to access, and not interoperable. The new international Leiden Institute for FAIR and…

The annual LION Image award goes to the 30 micrometer long 3D printed microboat image that went viral earlier in October 2020, submitted by Rachel Doherty of the Daniela Kraft lab.

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…

Marlon Titre (1982) studied at Royal Conservatoire The Hague, did his PhD and studied at Leiden University, earned several other qualifications and is now, among others, Director of Filmhuis The Hague. Who is this multi-talent?

Leiden patriot Pieter Vreede fought for greater popular influence. Historian Dirk Alkemade reveals how this pioneer used radical means to shape Dutch democracy.

The two instruments of ESA's space telescope Euclid have taken their first test images. The first images indicate that the space telescope will achieve the scientific goals for which it was designed - and possibly much more. Euclid will create a 3D map of a third of the sky, allowing scientists to study…

It was not until 1878 that the first female students enrolled at Leiden University, but the discussion on whether women were suited to study was by no means over. 8 March is International Women's Day. BBC correspondente Kim Ghattas will deliver a lecture on 6 March on the struggle by Arabic women for…

The European Space Agency (ESA) has published an interim data release from Gaia, the space telescope mapping out the Milky Way in 3D. The first scientific papers published today reveal half a million stars in the Omega Centauri globular cluster, nearly 400 candidate gravitational lensers and the positions…

In supermarkets, consumers are drowning in a sea of sustainability labels. Confusing for them, but also farmers can't see the forest for the trees. Obtaining these labels demands an enormous amount of time and effort. Berent Baris is investigating ways to simplify this process, benefiting both farmers…

How do we know what a quantum computer is good for when it hasn't been built yet? That's what PhD candidate Casper Gyurik investigated by combining two terms you often hear: quantum computing and machine learning.

Good education starts with good educators. The university has taken various steps in recent years to help our teaching staff develop. But new teaching staff require particular attention, say staff who work on teacher professionalisation.

Prof. Marcel Reinders is a data science specialist at Delft University of technology. Using smart algorithms, he searches for links in complex data. For example, he studies patterns in DNA that lead to aberrant cell behaviour. This knowledge will help detect serious diseases such as Alzheimer's and…

Jasper Knoester is the dean of the Faculty of Science. How is he doing, what exactly does he do and what does his day look like? In each newsletter, Jasper gives an insight into his life.

Whom do you ask for permission to conduct research at a primary school? And how do you collect data in countries where freedom of expression is under threat? This is what staff directly involved in the – often complex – process of research ethics recently discussed at a meeting, with the aid of some…

Would you like to share your expertise with a wide audience, and in a very convenient way? The Vraag het Leiden (Ask Leiden) video platform is looking for academics who can answer questions sent in by the general public, both young and old, by recording short videos.

Innovative, future-proof teaching methods were the theme of the tenth Leiden Teachers’ Academy Education Conference that took place on 5 June.

Leiden University is joining the Una Europa European University. Together with other partner universities Leiden University will draw on their collective strengths to shape the future of Europe through innovative education, research and international exchange.

Dean of the Faculty of Science Jasper Knoester gives a glimpse into his life every two weeks. This time he takes a tour with the Executive Board and visits two institutes of our Faculty. ‘For administrators, these are informative and stimulating opportunities, which unfortunately don't happen often…

Cancer research generates massive amounts of data, but traditional tools often fail to fully harness their potential. How can we unlock this data to provide better treatments for cancer patients? PhD candidate Marina Gorostiola González explored this by using advanced data analysis techniques to guide…

How satisfied are you with your work? And how can we improve? On Tuesday 6 May, our partner Welliba will invite you to take our 2025 Employee Experience Survey. We want your opinions on your workload, a respectful culture and more.

The university makes staff aware of the importance of cybersecurity at work. And that is essential, say our privacy and security officers. Because the number of cyberattacks is increasing, hackers are getting smarter all the time and by far the majority of problems are caused by human error. ‘Is that…

Did he dare take a gamble with his PhD research? Jeroen Methorst didn’t have to think long about it. It could fail or turn out very well. The latter is the case. Methorst developed a computer system that helps researchers find the protein they need. ‘Our whole group is now using this program.’ Methorst…
