Research and design are two activities that are becoming increasingly important in the Dutch subjects O&O (‘research and design’) and NLT ('nature, life and technology’). The dissertation of Tessa Vossen (ICLON and Faculty of Science) indicates that teachers and students understand the importance of…

Leiden has a long history in the treatment of blood cell cancer. Research to find better therapies never stands still. One of the potential treatments currently being worked on is a ‘living medicine’.

The research in this thesis is focused on tomographic reconstruction based on two imaging modalities in electron microscopy.

How can we broaden youth participation in STEM Learning

Treatment with special stem cells seems to be a good option for suppressing the immune system in organ transplants. Researchers are trying to learn from processes that take place in the human body during pregnancy.

Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

The Netherlands Organisation of Scientic Research (NWO) has granted the VIDI application of Dr. Miguel John Versluys for the research of Cultural innovation in a globalising society: Egypt in the Roman world.

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

This dissertation focuses on the systematic vowel alternations displayed by the Proto-Germanic n-stems. The fact is, that many of these nouns now appear to have preserved the ablaut system of the Indo-European proto-language spoken some five millennia ago. In this respect, the n-stems are truly comparable…

Dr. Miguel John Versluys (Archaeology) has been awarded a prestigious Vici grant for his project:

Dr. Miguel John Versluys was awarded the Zenobia Essay Prize during the recent conference Troy: the city, the war, the legend organized by the Zenobia Foundation in the Lutheran church in Amsterdam.

Physicist Christopher Berg Smiet, who recently obtained his PhD in Leiden, has been awarded an NWO Rubicon. The grant allows him to conduct postdoctoral research for two years at the Princeton Plasma Physics Laboratory (PPPL) in the United States.

The Leiden University Medical Center (LUMC), the Danstem Institute from the University of Copenhagen and the Murdoch Children’s Research Institute in Melbourne have received 300m euros from the Novo Nordisk foundation. The aim of this new international consortium is to bring stem-cell based therapies…

From 1 December 2019, Miguel John Versluys, Professor and Chair of Classical & Mediterranean Archaeology at the Faculty of Archaeology, will join the Supervisory Council of the National Museum of Antiquities in Leiden (RMO).

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…

The Leiden Observatory is starting a crowdfunding campaign to raise enough money to construct a new telescope.

This lecture will be hosted on Thursday, 9 April 2026 at 6:00 pm - 10:00 pm.

A team of astronomers led by Dutch scientists have directly imaged a giant planet orbiting at a large distance around a sun-like star. Why this planet is so massive, and how it got to be there, is still a mystery. The researchers will publish their findings in the journal Astronomy & Astrophysics.

Chemist Roxanne Kieltyka has received an ERC Starting Grant of 2 million euros. In her lab, she creates gels that mimic the instructive material that supports cells in our body. With the grant, she aims to make these gels stiff and tough, and to create a bio-printed miniature heart ventricle.

Embryonic stem cells have the remarkable ability to develop into any type of cell. On their way to become for example a liver or a heart cell, they must repeatedly decide between alternative developmental paths. How they make these decisions is largely unknown. An international team of biophysicists…

Researchers and clinicians at Leiden University Medical Centre (LUMC) are about to begin a milestone clinical study. It will be the first time a stem cell gene therapy developed in the Netherlands is used in a clinic. The therapy will be used to treat children with SCID, a rare disorder where children…

Researchers from the Leiden University Medical Center (LUMC) have successfully used stem cell gene therapy to treat a baby with the severe congenital immune disorder SCID. An important milestone: it is the first time stem cell gene therapy of Dutch origin has been administered to a patient, and also…

Staring into the clouds hoping for a glimpse of the sun, cheering in encouragement, video recordings: there was no shortage of things to do at the Leiden Observatory. More than 600 visitors witnessed the last, almost complete solar eclipse of the decade..

A team led by Leiden University in the Netherlands and the National Radio Astronomy Observatory have, for the first time, robustly detected semi-heavy water ice around a young sunlike star. In this ice, some of the ordinary hydrogen atoms have been replaced by deuterium, a heavier variant of hydroge…

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

Three speakers, three fascinating science stories and a well-filled lecture hall. The Niko Tinbergen Lecture had a successful restart on 10 December 2019.

ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate - a chemical building block of life. This is the first ever detection of this prebiotic molecule towards solar-type protostars, the sort from which our Solar System evolved. The discovery…
