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…

Leiden physicists Alexandre Morin and Samadarshi Maity study self-organisation and flocking phenomena. They shed light on flocking, which helps to understand how it is possible that birds in a flock don't collide. With plastic microbeads, they create an experimental setup and they developed a mathematical…

The Faculty Board awarded 16 starter grants to young assistant professors for their research proposals.

The final meeting which took place on Wednesday 6 September marked the end of the third cohort of master students’ time participating in the The Hague Southwest Thesis Workshop. During this last meeting, master students presented their research results to residents and stakeholders from The Hague So…

It will be a summer filled with conferences at the Faculty of Humanities in Leiden. In the coming months, there will be something for everyone at the university, especially in the field of languages and cultures of Africa and the Middle East.

Young people influence one another to take greater risks, although it's not quite that cut and dried. This is what development psychologist Jorien van Hoorn discovered. Peers also have a positive influence on one another, an aspect that has so far been under-researched. PhD defence 12 January.

Spatial technology such as virtual reality can help patients who have difficulty with spatial cognition, for instance if they keep on losing their way. In her inaugural lecture, neuropsychologist Ineke van der Ham will talk about the importance of avatars, the patient experience and room for innovat…

Scientists' computers are now full of complicated 3D models, but no standard has yet been developed for exchanging the data. A new database should change this. External PhD student Liselore Tissen is receiving a grant to contribute to this on behalf of Leiden University (and TU Delft). ‘It will be great…

The moving boxes are unpacked, the floors are gleaming, and the workshop rooms look fresh and inviting. On Monday 16 June, the renovated Lorentz Center will be officially reopened by dean Jasper Knoester and rector Hester Bijl. Director Roeland Merks: ‘There’s a new energy running through our centre…

Why did fewer women suffer from osteoporosis in the past than today? And which aspects of a city make public spaces safe, accessible and comfortable for all residents? These two research questions will be explored in more detail thanks to an Impulse Grant from the Leiden University Fund.

In a new study published in PLOS One, Leiden archaeologist Anastasia Nikulina, together with an international team from France, Denmark, the United Kingdom and the Netherlands, challenges the long-held belief that early humans had minimal impact on their environment before the rise of farming.

Mini organs-on-chips allow us to study how diseases develop and how drugs work. Although the technology is not new, it is becoming increasingly advanced. PhD candidate Bart Kramer hopes it will eliminate animal testing in the future.

Leiden University's International Honours College, Leiden University College The Hague (LUC) experienced empty halls and empty classrooms this past year on the residential campus on the Anna van Buerenplein in The Hague due to the global pandemic. Dr Paul Hudson designed a Covid-proof course that enabled…

A team of European astronomers has found a silicate-based weather system on a cloudy gas planet around the star WASP-107. It is the first time astronomers have found silicate clouds and rain. They also conclude that temperatures deeper in the atmosphere are rising rapidly. 'The presence of clouds has…

Two Leiden University science communication projects have been awarded a WECOM grant through the Dutch Research Agenda (NWA). One project is a study of the history of the deaf community in the Netherlands and the other is of a condition that causes people to lose their way.

For ten months, PhD student Sanne Rotmeijer worked on the editorial boards of various news media on Curaçao and Sint Maarten. She also tracked how news goes around on the streets and circulates on social media. The aim? To find out how stories became 'the news'.

The Corstens Commission that investigated whether there are any grounds for the rumours of antisemitism at the Faculty of Law has found no indication whatsoever for such expressions. This also applies to the professor in question. This is evident from the report that the commission chaired by Professor…

Two Leiden legal scholars have been awarded funding from the KNAW pilot fund 'Science communication by scientists: Appreciated!'. The fund supports scientists who have demonstrated a continued commitment to science communication.

Too expensive groceries, diseases suddenly breaking out: from the sixteenth to the nineteenth century, hundreds of people documented the world around them in chronicles. A significant number of these texts have been digitised in recent years. Professor of Early Modern Dutch History and project leader…

Amphorae are usually associated with the ancient Phoenicians, Greeks and Romans. ‘​​​​​​​Yet, in some cases, such as Byzantium, amphorae existed for centuries after Antiquity.
