Following in the footsteps of Professor Jan Zaanen, visiting fellow Louk Rademaker is exploring quantum effects in so-called strange materials. His research is paving the way for new materials that could be used in emerging technologies.

17 November is all about high tech. From consultations with ASML and a component for the world's largest telescope to our high-tech education. Oh right, and a conversation with the new rector magnificus.

It doesn't happen every day that the research project of a first-year bachelor’s student results in a scientific publication. And not only that, but as first author and on the cover of a leading physics journal. ‘We have given our lab education a thorough overhaul and it is paying off.’

Due to its success, the Leiden2022 Q&A has been extended and is looking for even more thought-provoking, interesting or unusual questions.

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,…

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…

From the birth of the universe to the molecules in a planet's atmosphere. The first five pictures from the James Webb Space Telescope (JWST) show the enormous range in which the space telescope can operate. Ewine van Dishoeck, professor of molecular astrophysics, took a look at the first images Tuesday…

As a mathematician, Fred Rohde (1948) explored the world of numbers. As a photographer, he captured demonstrations. And now he’s reconstructing his mother’s wartime story – an extraordinary tale of her stay with an Austrian family, the inventors of asbestos cement.

Two directors. Both professors of mathematics, but one of them is a biologist. One comes, and the other goes. Roeland Merks will succeed Arjen Doelman as director of the Lorentz Center in September. What has been accomplished and what are the plans? And above all, what makes the Lorentz Center so un…

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.

Jasper Knoester is the dean of the Faculty of Science. How is he doing? What kinds of things is he doing and what does his day look like? In each newsletter Jasper gives a peek into his life as dean.

An international team of astronomers, including Leiden PhD student Elia Pizzati, has observed several ancient quasars that, surprisingly, appear to be floating alone in the early universe (less than a billion years after the Big Bang). Until now, astronomers, based on models, assumed that quasars are…

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.

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.

On March 28, 2023, our esteemed colleague Prof. Harry Wijshoff passed away. He died after a struggle of several months against a serious illness.

The Dutch Research Council (NWO) is investing 197 million euros in 11 infrastructure projects that will be of great value to science and society. Leiden University and the Leiden University Medical Center (LUMC) are participating in eight of the eleven proposals.

Technology holds so much promise – from self-driving cars to enhanced physical performance from smart implants under the skin. But we should not let ourselves be caught off guard. That is the message of Bart Custers, Professor of Law and Data Science in his inaugural lecture on 21 May. ‘We don’t talk…

To what extent does exoplanet Proxima b resemble our Earth? And is there some form of life present? Astronomers hope to find answers to these questions with the new European Extremely Large Telescope (ELT). An NWO research grant of €18 million will allow a Dutch consortium to continue building instruments…

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…

Pre-University College The Hague is celebrating its fifth anniversary in 2024-2025. Three alumni look back on their experience. PRE broadened their academic horizons and taught them a lot about themselves. ‘PRE made me feel more comfortable at university'.

Bring over a hundred driven researchers together in one room and the good ideas will start to flow: that was the thinking behind the internal networking meeting on interdisciplinary collaboration on Wednesday 17 May. Representatives from the nine interdisciplinary programmes were waiting at their stalls…

Do you want to provide advice on issues of your own choosing, and help decide on important subjects within the university? If you do, then it’s time for you to stand as a candidate for a faculty or employee council. ‘Standing for election is a good way for you to join in the dialogue. We don’t just…

An international team of astronomers has revealed the first 'chemical profile' of an exoplanet's atmosphere. The team, including Leiden astronomer Yamila Miguel and provenda Amy Louca, made the profile using so-called Early Release Science data from the James Webb Space Telescope. The results have been…

How has evolution shaped our curiosity? And how does that curiosity ensure that we now have the technological ability to discover whether we are alone in the universe? This was all covered during the celebration of Leiden University’s 449th Dies Natalis.

Two deans: one leaving and one just arriving. Paul Wouters was deputising at the Faculty from March up to December. As of January he returns to his 'ordinary' role as dean of the Faculty of Social Sciences. Jasper Knoester is taking over from him, as he will be leaving Groningen for Leiden. How did…

The orbits of 27 stars orbiting closely around the black hole at the center of our Milky Way are very chaotic. As a result, researchers cannot predict with confidence where they will be in about 462 years. ‘That is astonishingly short,’ says astronomer Simon Portegies Zwart who collaborated on the r…
