How do biological cells join forces to form a structure? In her PhD research, Daphne Nesenberend uses mathematics to show how forces and cooperation between cells create structure – and how simulations and experiments can reinforce each other.

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…

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.

Nanoplastics can accumulate in developing hearts, according to a study by biologist Meiru Wang from Leiden University. Her research on chicken embryos sheds new light on how these tiny plastic particles pose a threat to our health.

Fossil teeth can preserve remarkable information, much like a biological identity card with data about the lives of individuals tens of thousands of years ago. By analyzing teeth, a new study published in Science Advances reconstructed the life history of four straight-tusked elephants (Palaeoloxodon…

No more ones, twos or threes, but focusing on development opportunities. This summer, the Faculty of Humanities will start a pilot for the new Performance and Development Interviews (PDI). HR adviser Marion Sluijs tells us more about it.

As the election period approaches, we asked Marie Kolbenstetter, PhD candidate at the Faculty of Archaeology and current member of the University Council, to reflect on her experiences in both the Faculty Council and the University Council. Her insights offer a candid look at what participation means…

By day, Roeland Merks works on mathematical models that describe cells and complex systems. In the evenings, he opens the door to a different world. In his home and art space De Spelonk, contemporary art, experimentation and curiosity come together — right at the intersection with his scientific per…

Our institute is in full swing: the annual staffing review, Recognition & Rewards, Open Science and the introduction of GROW. Besides these positive developments, Hanneke Hulst also sees concerns, for example about the new outline agreement. 'I’m hopeful that together we will find smart ways to deal…

Protest is a human right and an important way to hold the authorities to account. But how does the right to protest relate to academic freedom and the right to education?

Astronomers who simulate galaxies do not always get the same result, even when they start from identical conditions. New research from Leiden University shows that this is not a flaw, but a consequence of how galaxies behave — and how they are modelled.

What happens when you let go of the traditional essay and instead invite creativity, imagination and experimentation? Honours College Law students found out with 'unessays', now showcased in an exhibition at the KOG.

Sharing your knowledge with a broad audience? It’s fun – and it brings you something as well. Researchers Dietsje Jolles and Rachel Plak can attest to that. They have been taking part in science events for years. ‘Contact with the public leads to new insights.’

Professor Miguel John Versluys of Leiden University has been recognised with the esteemed Humboldt Research Award, a testament to his groundbreaking work in global archaeology, reception-studies and the deep history of globalisation. The award, granted by the Alexander von Humbold-Stiftung, celebrates…

On Wednesday 19 January 2022, the online mid-term review of the legal programmes took place on the platform Let’s Get Digital. It was an interactive afternoon in which 130 participants openly and critically discussed the educational strategy for the legal programmes and the faculty.

In traditional style, 2025 was ushered in at our faculty with the Meijers Lecture followed by the New Year's Reception. On Thursday 16 January 2025, the Meijers Lecture took place in the Lorentz Lecture Hall where the Meijers Prizes and the Van Wersch Springplank Prize were also awarded. At the New…

A million people in the Netherlands attempt to quit smoking each year, often without lasting success. Health psychologist Kristell Penfornis carried out doctoral research into the role of self-image in smoking cessation. “If smoking is normal in your social circle, it more easily becomes part of your…

There is a real chance of war closer to home, political and military leaders in Europe have warned. What does Frans Osinga, Professor of War Studies, think about the threat and what we should do?

In line with the university and faculty ambition: ‘Future-oriented development of students’, from now on all FSW bachelor students can follow a three-year elective, faculty programme with certificate for personal-professional development, the programme starts with current first-year students; they are…
