How can you ensure that more experimental drugs reach the finish line? At the moment, only one in twenty cancer drugs that are tested on humans makes it to the market. This is an enormous loss for patients and society. With a grant from the National Growth Fund, Oncode-PACT aims to efficiently select…

Bacteria carry countless hidden treasures in their DNA: fragments that could hold the key to new medicines. But how do you pick out the most promising ones from millions of options? ‘Look at the switches that turn genes on and off,’ says molecular biologist Gilles van Wezel.

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…

Why are morpho butterflies blue? That is what high school students Frederique Kerstens and Koen van Griensven investigated in their high school profile paper at the Leiden Institute for Research in Physics. In doing so, they won the KHMW Profielwerkstukprijs 2023. ‘We didn't expect it, but are of course…

Research into depression in children, Leiden alumni in the Dutch House of Representatives and an exceptional achievement by one of our students: what do this topics have in common? They are among our most read stories of 2021.

Jasper Knoester is de decaan van de Faculteit Wiskunde & Natuurwetenschappen. Hoe gaat het met hem, wat doet hij precies en hoe ziet zijn dag eruit? In elke nieuwsbrief geeft Jasper een inkijkje in zijn leven.

With the aid of physics and a minuscule magnet, researchers have discovered a new structure of telomeric DNA. Telomeres are sometimes seen as the key to living longer. They protect genes from damage but get a bit shorter each time a cell divides. If they become too short, the cell dies. The new discovery…

Jasper Knoester started on 1 January as our new dean. How is he finding it, what kinds of things is he doing and what does his day look like? In every newsletter Jasper gives us a peek into his life as dean.

Sixteen researchers at Leiden University are to receive a Veni grant from the Netherlands Organisation for Scientific Research (NWO). These awards offer promising young researchers the opportunity to further develop their own ideas over a period of three years.

Western civil servants openly struggle with their government’s policies on the war in Gaza. During a meeting at Campus The Hague, three former civil servants told their stories.

Defending your PhD research in front of nearly 300 elementary school students: that was the challenge faced by PhD candidates Jo-Anne Verschoor and Marinka de Willigen during the VUURVLIEGEN competition organised by the Centrum JongerenCommunicatie Chemie (C3). After an exciting competition, the children…

Designing innovative algorithms, thinking outside the box, and brainstorming over coffee with his colleagues — this is what physicist Stefano Polla enjoys most. His success shines through in his nomination for the C.J. Kok Jury Award 2024 for PhD thesis of the Year.

An international team of astronomers has discovered a large reservoir of hot gas in the cluster-in-formation around the Spiderweb Galaxy. Based partly on that hot gas, the astronomers predict that the cluster-in-formation will grow into one of the largest objects in the universe. A step closer to discovering…

Why do some people with adverse childhood experiences develop mental health conditions whereas others do not? A Leiden research project is looking for volunteers aged between 18 and 24 to help us understand more about human resilience.

Soil ecologist Emilia Hannula has been awarded a Vidi grant by NWO to examine how soil could become a promising ally in combating climate change and improving biodiversity. ‘Soil creatures might be invisible’, she says, ‘but they play a huge role in creating a healthy environment.’
