Tuberculosis stands as one of the most lethal infectious diseases worldwide. A significant challenge in combatting tuberculosis lies in the emergence of antibiotic resistance triggered by genetic alterations, commonly known as mutations. These mutations can diminish the responsiveness to antibiotics,…

In summer 2018 classical archaeologist Hanna Stöger passed away. At that moment she was in the midst of several cutting-edge research projects on the use of space in the Roman city of Ostia. To make sure that her groundbreaking work would not go unpublished, long-time colleagues Hans Kamermans and Bouke…

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.

Various Leiden researchers have been awarded a European grant to explore the commercial or societal potential of previous research.

After receiving positive feedback from peers, socially anxious young people feel as confident about themselves as their non-anxious counterparts. 'These young people are then able to handle new social situations more confidently,’ says Leiden psychologist Anne Miers. Her research is published in the…

Evidence that the right diet can prevent or alleviate depression is weak. In literature reviews on the subject, the authors often reach strong conclusions, nonetheless. This is what Florian Thomas-Odenthal, a master’s student in Psychology at Leiden University, discovered in his thesis research. Publication…

It does not happen very often that a research project for a second-year bachelor's course gets turned into a proper academic paper. But International Studies students Pia Kurz, Coleen Gonner and Monika Bartnicka did just that. How did they manage it?

The race to build the first quantum computer is still ongoing, but Morten Bakker has made big step forward in that process with qubits. A qubit is a unit of quantum information that can be produced in large numbers on chips. Qubits capable of exchanging photons (light particles) could be used in the…

Friday 5 July 2019 was the graduation of the Advanced Master International Relations and Diplomacy (MIRD). ´If the MIRD is like a good wine, this has been a vintage year'.

How do you ensure that a drug has an effect on the right protein – and nothing else? Chemist Anthe Janssen explored various methods for determining the selectivity of potential medicines. He also looked at the substance BIA 10-2474, after a man died in a French clinical trial in 2016. PhD defence on…

If you expect something is going to itch, the itching really does get worse. Leiden health psychologist Danielle Bartels has proved the effect of negative expectations on itching. What’s remarkable is that this nocebo effect in itching can be reversed. ‘That offers good prospects for clinical practice,’…

Om de weg te vinden letten sommige mensen op de omgeving, anderen onthouden waar ze links of rechts af moeten slaan. Mensen met Niet Aangeboren Hersenletsel (NAH) rapporteren navigatieproblemen. Om opnieuw te leren navigeren heeft neurowetenschapper Milan van der Kuil als revalidatietherapie een serious…

After almost four decades, Leiden and Eindhoven chemists have resolved the discussion about the correct model for the simplest chemical reaction in heterogeneous catalysis, which is essential for fuel cells. Using a unique curved platinum surface, Ludo Juurlink and PhD candidate Richard van Lent from…

The 2025 Data for Policy conference at Leiden University explored how digital and green transitions can shape a more sustainable and inclusive future.

Positive expectations about a medicine may help it to work more effectively, even if you tell patients about this placebo effect. The reverse, the nocebo effect, works in the same way. Health psychologist Stefanie Meeuwis found evidence for this in various studies. PhD defence 3 June.

Physicists propose the existence of sterile neutrinos that would explain three big mysteries in nature. To actually find them in particle accelerators, researchers need to know how they are produced and how they decay. PhD candidate Kyrylo Bondarenko has made predictions about this, which are currently…

Stephan Raaijmakers has been Professor of Communicative AI since 1 May. Prior to this, he had held this position for five years as professor by special appointment. How has his approach to AI changed in that time?

All manuscripts submitted to Inter-Section need to adhere to these guidelines. Since 01-08-2022 Inter-Section uses APA7 as a reference system. Inter-Section therefore now follows the new Faculty of Archaeology guidelines concerning referencing and bibliography.

How did the medieval manuscript develop as a physical object during the Twelfth Century Renaissance and what do these changes tell us about the intellectual culture of the period?

Archaeologist Prof Bleda Düring has been awarded a prestigious ERC Advanced Grant for his research on the emergence of social inequalities in the transition from the Copper Age to the Bronze Age in Cyprus. Using excavations, isotope analysis and cultural interpretations, he investigates how and why…

Leiden University Libraries holds an internationally unique collection of unofficial poetry from China. Produced outside the System over the last fifty years or so, this poetry is hugely influential yet hard to find beyond the informal networks through which it travels. To address this paradox, the…

This year, an NWO PhD in the Humanities grant went to Mink van IJzendoorn, enabling him to investigate the disappearance of amphorae. ‘We take means of packaging and shipment for granted, but they are deeply ingrained in our daily lives; they are crucial.’

Bird, butterfly, fish: when you look through a children’s book, you usually don’t think about the fact that humans divided these animals, depicted in bright colours, into categories. Yet, this division has been discussed for centuries. In her PhD dissertation, Didi van Trijp shows how natural scientists…

How do you move 3,000 fragile clay tablets that date back thousands of years? This was the challenge faced by staff from the Netherlands Institute for the Near East (NINO). After years of preparation, the Liagre Böhl collection has been moved on trolleys to its new home.

Researchers from Leiden see hungry villagers in the north of Cameroon steal meat from the prey of lions. The researchers from Leiden University's Institute for Environmental Sciences (CML) reported on this kleptoparasitism in the online publication of the African Journal of Ecology in July.

How can the Netherlands be better prepared for infectious diseases transmitted by mosquitoes. The Dutch Research Council (NWO) has awarded almost 9 million euros for this research. Maarten Schrama from the Institute of Environmental Sciences CML coordinates the input of Leiden University within the…

The oldest forms of literature and law originate from Mesopotamia (3000 BC until AD 70), as do important discoveries in science and technology. All these developments were recorded in cuneiform texts on clay tablets. There is still a lot to learn from the study of cuneiform texts, says Professor of…

Leiden astronomer Xander Tielens has been awarded a Spinoza prize, the highest scientific prize in the Netherlands. Tielens is Professor in the Physics and Chemistry of Interstellar Space.
