What did we do over the past year? Well, we played quantum games, helped develop an instrument for the Extremely Large Telescope and started a new bachelor's programme. Oh, yeah, and we officially opened our brand new Gorlaeus Building! Warm up the fingers and get ready to click and scroll through…

An accurate description of reactive scattering of molecules on metal surfaces often requires the modeling of energy transfer between the molecule and the surface phonons. Although ab initio molecular dynamics (AIMD) can describe this energy transfer, AIMD is at present untractable for reactions with…

This thesis discusses the discovery potential of Intensity Frontier experiments.

Ecotox is located in an ambitious surrounding at the Leiden University. It is an initiative of both institutes Institute of Environmental Sciences (CML) and Institute of Biology Leiden (IBL).

This thesis aims to investigate the effect of tripartite interaction between microbial inoculants, the plant, and herbivore insects on the rhizosphere microbiome and volatilome. We investigated the rhizosphere microbiome and volatilome of tomato plants exposed to insect herbivory and/or inoculated with…

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

Social Science Matters is an online variant on London’s famous Speakers’ Corner – a platform for the researchers in the various disciplines in the Faculty of Social and Behavioural Sciences to react to the news. This soapbox gives our social scientists an opportunity to voice their opinions on current…

It is our goal to deliver a convenient, enjoyable, learning experience that goes beyond the basics. All of the apps are an initiative of the HANDS! Lab for Sign Languages and Deaf Studies at Leiden University, as part of the Language Socialization in Deaf Families project funded by the Leiden University…

Artful Mathematics: The Heritage of M. C. Escher

In this article, Tokdemir & Klein examine the strategic actions of governments against domestic terrorist groups and domestic terrorist groups’ reactions to such actions.

In previous studies at our laboratory it was demonstrated that drug exposure of HepG2 cells can lead to an altered TNFα-induced NF-κB oscillatory phenotype, concurrent with a synergistically increased sensitivity for TNFα-induced apoptosis.

The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

Microbes influence and respond to other organisms. This theme explores the dynamic relationships within plant and animal microbiomes, and the immune responses that govern host defense. Using model systems such as zebrafish, insects, and plants, we investigate fundamental processes and engineer microbes…

In the track Intelligence and National Security you will be introduced to intelligence and security services in their political, societal, and bureaucratic contexts. The track will give you a thorough understanding of the modus operandi of these agencies, their interaction with the surrounding world,…

Packages of DNA strands containing silver, measuring just two or three nanometres in size. Leiden physicists Donny de Bruin and Dirk Bouwmeester create these packages, which can enter living cells on their own. They then activate the silver with light, causing the cells to break down. This could, in…

An overview of awards and prizes granted to our staff and students in 2022, as well as special appointments at Leiden University and other institutions.

Stacked layers of graphene can act like a mirror for beams of electrons. Physicists Daniël Geelen and colleagues discovered this using a new type of electron microscope. In an article in Physical Review Letters, they describe their results, which could lead to the development of optics for electron…

The Dutch Research School for Theoretical Physics (DRSTP) has received excellent ratings from an independent international committee. The DRSTP is a school for PhD training which has grown out of a collaboration between the theoretical physics departments at six Dutch universities—including Leiden—and…

Human cells are protecting their proteins from unfolding and aggregating. That's what biophysicist Alireza Mashaghi and his team discovered after seven years of in-depth research into the folding mechanisms of proteins. With an unprecedented approach, the team was able to study the folding of a single…

Thanks to a €4.8 million grant from the Dutch Research Council, a consortium that includes four physicists from Leiden University will develop a national facility for atomic-scale research into novel materials. This initiative is expected to drive innovation for energy transition.
