De Code voor Kinderrechten op het internet toont makers van apps en games hoe zij de rechten van kinderen kunnen beschermen en meenemen in hun ontwerp. Dat is hard nodig, zeggen de opstellers hoogleraar Recht en Digitale Technologie Simone van der Hof en onderzoeksdirecteur Sander van der Waal van stichting…

Waarom laaien er rellen op in het Verenigd Koninkrijk, aangespoord door de extreemrechtse British Defence League? Jorieke Manenschijn sprak met EenVandaag over hoe de beloftes van Brexit aan de woede hebben bijgedragen.

The financial sector, supply chains and ecology. Not necessarily topics you might associate with physics, yet it’s exactly what new professor Diego Garlaschelli is dealing with. The common thread? Complex networks.

Not all problems are easy to solve, but with enough bright minds, you make progress step by step. ‘The kind of problems I am interested in have been occupying mathematicians for over two millennia,’ says theoretical mathematician David Lilienfeldt. In September, he started at the Mathematical Institute…

Does gravity work the same when you look at the largest scales in our universe? That’s what Leiden physicist Alessandra Silvestri will study with a 2 million euro ERC Consolidator grant. ‘We assume that it does, but we don’t actually know.’

The city of Leiden has a unique combination of knowledge institutions. To ensure this knowledge flourishes and the city gains the maximum benefit from it, the Leiden City of Knowledge partnership was launched five years ago. A new partnership agreement will be signed on 11 November.

PhD candidate Ludwig Hoffmann will spend two years at Harvard University in the US thanks to a Rubicon grant he won on April 11. Using theoretical models he studies biological tissues, for example during morphogenesis. This is the process that causes tissue or organisms to develop their shape. ‘This…

Alex Colling himself calls his bachelor's thesis ‘the highlight of his time in Leiden’. And according to his supervisors, that resulted in an outstanding thesis, with great attention to detail. The Mathematics and Physics student worked on a mathematical description of monopoles: hypothetical particles…

Swarms of drones, pedestrians or the cells in your body. Those are all examples of active matter: materials whose building blocks can move autonomously. That’s what Luca Giomi studies. Giomi has been appointed Professor of theoretical physics in the area of soft matter and biological physics at the…

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.’

Working for a social client during your studies: this is what happens at Urban Studies. For the course Urban Studies in Practice, third-year students carry out projects for public clients, such as the municipality of The Hague.

How would you convert Egyptian hieroglyphs into Latin script? And what is actually the correct translation of dishes on a Vietnamese menu? On Saturday 28 January, high school students from all over the Netherlands will come to Leiden to ponder a series of language-related puzzles. Their goal? To win…

We want FGGA to become a place where everyone feels welcome, at ease, and included. The outcomes of last year's personnel monitor and D&I survey show that we are not quite there yet.

Exploring the largest structures in the universe by looking at the tiniest particles? Lydia Stofanova, PhD candidate at Leiden Observatory and SRON Netherlands Institute for Space Research, dives into this intricate connection. In her PhD research, she explored how elements like oxygen influence the…

Accelerating the development of new cancer medicines by joining forces—that’s the mission of Oncode Accelerator, a Dutch consortium that recently welcomed three Leiden-based PhD candidates. Under the guidance of Gerard van Westen, Marc Boef, Remco van den Broek, and Lucina-May Nollen are exploring how…

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.

Salt crystals, a nano-sized golf stick and molten glass. The LION Image Award competition of 2023 yielded a lot of beautiful images once again. But in the end, only one can be the winner.

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 ‘Engagement with Society’ ambition is closely linked to the ‘Employability Enhancement’ and ‘Skills’ ambitions. Introducing students to social issues often gives them immediate insight into the job market they will enter. And working on social issues gives them the opportunity to develop skills…

Henk Hoekstra and Alessandra Silvestri work on the astronomy and theoretical physics in the Euclid mission. These Dutch researchers are part of the mission.

Luca Giomi has the first results of his ERC consolidator grant. He discovered that epithelial cells move collectively but in different ways, depending on the scale you look at. It is hexatic at small scales, and becomes nematic at larger scales: it is a multiscale order. This collective movement of…
