How do humans construct their self?

Specific fatty acid-sugar molecules allow leprosy bacteria, among others, to hide from our immune system. How exactly is not entirely clear. Hessel van Dijk, who received his PhD on 13 October, replicated the molecules, helping to solve a piece of the puzzle. Van Dijk's dissertation is titled: Synthesis…

Innovation through repetition. That is how university lecturer Jurriaan Witteman describes his research on the automatic processing of angry voices in the brain. The original research was conducted 20 years ago, but, with an NWO grant, Witteman is now going to see if those results are accurate.

Is the possibility of computers making decisions for us in the future realistic? Holger Hoos, professor of Machine Learning, gives his opinion about the future of artificial intelligence in the television show ‘The future is fantastic’ on NPO3.

Chromatin is an ubiquitous protein-DNA complex that forms the structural basis of DNA condensation in all eukaryotic organisms.

The group Theoretical Physics of Life Processes, led by Helmut Schiessel, focuses on the physics of chromatin, the DNA-protein complex that fills the nuclei of eukaryotic cells.

Basketry, cordage and textiles made of plant fibers or bark are rarely preserved in the archaeological record. By means of experimental archaeology and microwear analysis, we obtain indirect evidence about this important craft.

Honorata Mazepus and Jaroslaw Kantorowicz are assistant professors at the Institute of Security and Global Affairs. Mazepus and Kantorowicz are one of the authors of this article in Nature on the role of national identity on public health support during global pandemics.

On May 31st, Bobby Ruijgrok succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Bobby on this great result.

In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

This study looks at population response to government containment strategies during initial stages of the COVID-19 pandemic in four high-trust Northern European countries–Denmark, Germany, the Netherlands, and Sweden–with special emphasis on expressions of governmental trust.

The relative simplicity of the bacterial cell, short generation times and well defined and inexpensive culturing conditions have significantly contributed to our understanding of many complex biological systems. Yet the workings of the bacterial genome, seemingly impossibly compressed within a tiny…

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

How do mycobacteria subvert the defenses of host immune cells?

This article explores how the meaning of the rule of law has evolved over the past century in UK and US parliamentary speeches, focusing on procedural (thin) and substantive (thick) conceptualisations.

Due to the almost complete disappearance of the archive of the Old Dutch West India Company (WIC, 1621-1674) not much is known about the ships and crews of this company. In this project we start the reconstruction of this basic information making use of new digital humanities techniques to extract this…

Circularity is an essential aspect of the industry transformation towards resource-efficiency, climate neutrality and long-term competitiveness. It can produce substantial material savings along value chains and production processes, generate added value and unlock economic opportunities.

This thesis investigates how the assessment of circular economy (CE) at the macro-economic level can be facilitated and promoted⁠.

The project aims to develop an escape room-style game to teach students cyber crisis management and prepare them for real-world cybersecurity challenges

To construct catalysts that can produce fuels from CO2 innumerable times, we need to learn much more about how catalysis works. Irene Groot is conducting groundbreaking research into catalysis at the atomic level.

Can epigenetic changes explain associations between early life stress and health outcomes?

Numerous beads and pendants of amber, jet and bone have been found in Dutch Neolithic and Bronze Age context, both in settlements and in graves. Because ornaments are personal items, they are closely linked with people’s identity.

Music can affect how we feel, think, and behave. But how do we learn about the specifics of people's responses to music so that we can apply this to health and well-being? By looking at characteristics of the music, as well as the differences between listeners, we hope to better understand as well as…

Assistant Professor Lucie Zicha at Leiden University College (LUC) in The Hague is on a mission to bring statistical literacy to all undergraduate students.

For two decades, language experts were certain that babies were able to learn language rules from as young as the age of seven months. However, recent research carried out by a consortium of four Dutch baby labs led by researchers from Leiden cast doubts on this certainty. We spoke to researchers Andreea…
