Proton therapy is a new way of treating cancer in which radiation doses are delivered more precisely. This results in less damage to surrounding tissue and fewer side effects. Professor Marco van Vulpen is medical director of HollandPTC in Delft, where the social value of this therapy is studied. Van…

Henk Versnel's work on ancient religion has been seminal. For his 80th birthday, a group of scholars assembled to celebrate and analyze his oeuvre.

The ultimate goal of the PhD program is the preparation and successful defense of a PhD dissertation.

A collection of newly written chapters by various specialists from different disciplines (with a background in philosophy) on the subject of free will as it is discussed in their (inter)disciplinary field.

Adhyāyas 96 – 112. The Varāha Cycle and the Andhaka Cycle Continued

The Dutch colonial past in Indonesia has had a major influence on literature.

Learn new ways to analyse and study cultures and languages and provides insight into how digital methods and artificial intelligence (AI) are changing our personal lives and societies in the minor Digital Humanities and Artificial Intelligence.

For many a first-year, student life has well and truly begun. This also applies to students in The Hague, who were thrown in at the deep end during the HOP introduction week. We paid them a visit on a sunny afternoon at Landgoed Clingendael.

Matthias Flór receives the KHMW Graduation Prize in Theoretical Physics for his master's thesis. His research on exotic superconductors at Leiden University and TU Delft struck a chord with the jury. The jury unanimously chose to award Flór noting that ‘he demonstrated impressive technical abilities…

On Wednesday September 26th, theoretical physicist Sean Carroll will give an Ehrenfest colloquium. It is part of a lecture series that has been running since 1912 and was founded by physicist Paul Ehrenfest.

To be able to measure small forces or small deviations from Boltzmann, the external vibrations at the resonance frequency must be very low. To achieve this, we have developed a very soft vibration isolation system and combine it with several other measures to reduce vibrations in our dilution refrigerators.…

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.

Leiden scientists and companies receive 1.37 million euros to develop technology for the Einstein Telescope. This underground telescope will measure gravitational waves and must therefore be extremely sensitive. To that end, the consortium conducts research on the damping of vibrations at temperatures…

Research on quantum computers and Islamic charities: two Leiden researchers have received a Consolidator Grant from the European Research Council.

Two Leiden Science researchers received an NWO-XS grant for their research. Both projects are highly promising, but also high-risk. Macrophages that trap bacteria and data storage made from 2D materials convinced the board of their potential.

Cryptographer Max Fillinger developed new methods to analyse a group of algorithms called commitments schemes. These schemes are building blocks for cryptographic protocols, which enable multiple parties that do not trust each other to work together safely. His PhD Defence is on 19 March.

PhD defence

Every year, the Leiden Institute of Physics (LION) organises the Science Day. The goal is to highlight the newest research at LION, to socialise, and to welcome first year master students and new PhD candidates to our institute.

Archaeometric analysis of glazed pottery assemblages from the Early Byzantine to the Early Modern periods in the Aegean.

Are there other planets like the earth, and will there also be life? Astronomers study planets around stars other than the sun, with the aim to find out what kind of gasses their atmospheres are made up with.

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

What are the mysteries behind soft condensed matter?

Detecting nanoscopic objects plays an important role in nanoscience in particular, in the rapidly growing field of nanobiology. The forebear to modern super-resolution microscopy for single molecule investigation, is fluorescence microscopy.

To study how planetary systems come into existence we study much younger systems still in formation.

In this thesis, I study the formation of large-scale structure and the physics of particle acceleration at large scales (~Mpc).

This PhD-research is conducted to test the hypothesis that Gutenberg and consorts developed a standardised and even unitised system for the production of textura type, and that this system was extrapolated for the production of roman type in Renaissance Italy.

A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

The CMCB brings together a diverse range of unique expertise in microbial cell biology. Members of the CMCB investigate both model and non-model organisms, bacteria and archaea, pathogens and non-pathogens.

In this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.
