A one-day conference was organised by the International Institute of Air and Space Law at Leiden University on 11 May 2023, in the lead-up to the 14th Leiden-Sarin International Air Law Moot Court Competition. The topic of the conference was ‘Aviation Cybersecurity’, which was also the topic of this…

On Saturday 19 November 2016 the students (9 – 12 years old) and several parents of the Transvaal University visited the Leiden University College (LUC) The Hague. The aim of the visit was to get acquainted with several scientific issues in an interactive session.

The Local Chamber of Associations (PKvV) has launched an online media platform that brings together all 24 Leiden student associations. It developed the platform over the past months in conjunction with Leiden University, University of Applied Sciences Leiden and Leiden Marketing.

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.

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…

The first direct detection of gravitational waves opened the possibility of mapping the Universe via this new and independent messenger.

This year, two Leiden physicists have earned a prestigious ERC Starting Grant. With a budget of 1.5 million euros, this is one of the largest individual grants for scientists.

The Graduate School of Science starts 2024 with a new Dean. The Faculty Council appointed Erik Danen for the coming four years. He succeeds Eric Eliel, who has held the position since May 2020.

Milan Allan has received the Bryan R. Coles Prize at the International Conference on Strongly Correlated Electron Systems (SCES) in Prague.

Philosophy is about the Big Questions: do human beings have free will? Is capitalism a just system? Does science provide an objective picture of the world? At Leiden, you will investigate fundamental questions of this sort from a global perspective. Through careful examination of different philosophical…

This Philosophy bachelor's programme offers perspectives from around the world. It will make you one of the next generation of students who will shape philosophy in the 21st century, ready to take on academic or professional challenges that call for critical thinking, analysis and argumentation skil…

The Microscopy Unit houses, maintains and coordinates most of the microscopy equipment of the IBL. The available equipment ranges from conventional light and fluorescence microscopes, to confocal laser scanning and electron microscopes. In addition, infrastructure is available for histology, including…

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…

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…
