The Faculty of Science launched the new Academic Year on 21 September with a special We Are Science talk show. Dean Paul Wouters starred in his role as talk show host and received a wide variety of guests.

What started as an idea during a social gathering led to an unexpected breakthrough in research on resistant bacteria. Biologists and chemists from Leiden developed a new substance that proves to be effective against bacteria resistant to antibiotics. They published their discovery in Nature Chemist…

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'.

Sebastian Pomplun manages to reach proteins with drugs even where this was thought impossible. That is why he and his research group have been allowed to join Oncode Institute. With nine others, he had been selected from 72 applicants to contribute to Oncode Institute's mission: to accelerate breakthroughs…

How do atoms and molecules end up forming planets? That's what astrochemist Julia Santos studied during her PhD. She discovered the dominant process behind the formation of methanol in space – a finding that surprised the entire field.

Molecular Science & Technology student Renske Donkers has won the second edition of the Young Star Award. During the ceremony on Wednesday 17 February, no less than three teachers were awarded the title 'Teacher of the Year'. Finally, students had a surprise in store for all teachers: with a video they…

The Honours Academy celebrates its tenth anniversary. How did the institute develop over time, and what are aspirations for the future? We speak with the current Dean and a predecessor who was there at the Academy's founding. A conversation about identity, inspiration, and impact ensues. ‘It is about…

The university was a gift from William of Orange to the people of Leiden for their courageous resistance to the Spanish. We’ve all heard the story of the university’s foundation. But its foundation was also a success story for two friends.

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…

Could water be present in planet-forming disks before the formation of rocky planets? The James Webb Space Telescope may have found evidence for that. Webb has for the first time observed water in the inner disc around young star where at greater distance, giant planets have already formed. The research…

For 25 years now, each faculty has had an assessor, a student representing the interests of all the faculty’s students. Yet few students are aware of this.

Smiling faces, sweltering heat and a record-breaking donation – that was the Leiden Science Run 2025. On Saturday 21 June, the Leiden Bio Science Park turned bright orange as enthusiastic runners completed 4.5 kilometres to support research for vulnerable children.

A single tiny molecule that can destroy flu, corona, HIV and Zika viruses? Yes, it really does exist. Biophysicist Niek van Hilten, who will receive his doctorate on 14 September, contributed to this discovery.

Quantum Rules lab van Leiden Universiteit biedt proefjes en experimenten voor middelbare scholieren om te leren over kwantum natuurkunde. Henk Buisman vertelt over het 5 jarige jubileum.

Since its discovery thirty years ago, it remained a mystery: how does the body’s own marijuana move between nerve cells in the brain? Mario van der Stelt and his research group have now uncovered the answer. This insight could aid the development of new treatments for pain and neurological disorders…

Leiden researchers have discovered an enzyme that helps bacteria feed on everyday plastics. This common enzyme could play a crucial role in future research and eventually in addressing the global plastic crisis. The study was published in Nature Communications.

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…

Scientific Director of the Leiden Academic Centre for Drug Research (LACDR) Hubertus Irth: ‘We test substances and look for new concepts for treating disease.’
