Elephant toothpaste, a trip among the stars or a lecture on mathematical juggling: on Sunday 8 October 2023, the Faculty of Science opened its doors for the third edition of the Leiden Science Family Day. A programme jam-packed with workshops, demonstrations, lectures and peeks behind the scenes for…

Cody Bahir defended his thesis on 1 June 2017.

This project aims to uncover a series of sites of difference and innovation. In particular, it locates itself in two kinds of distancing: geo-cultural (ie. in the non-European space of Japan) and medial (ie. in innovative expressive media).

The Leiden Bio Science Park (BSP) will become a real campus in the coming years, with more houses, and attractive places where scientists, students and entrepreneurs can meet to discuss their plans.

‘Space Antenna LISA will open an unprecedented window on the Universe,’ says astronomer Elena Maria Rossi. The mission will be the first one to detect Gravitational Waves from space. These can tell us more about the beginning of our Universe and the formation of black holes. With an NWO grant of twelve…

Planets existing in other solar systems contain invaluable information about the origin of planets and life. PhD candidate Yapeng Zhang has studied their atmospheres by looking at their smallest parts: isotopes. With her research she hopes to discover what makes our own solar system unique.

The Minor in Teaching was introduced in 2009 as a new initiative to introduce and prepare bachelor students for teaching. Student numbers are low, however, especially of mathematics and science students.

'We must set out an agenda, in partnership, to manufacture our own means. This will stimulate science, small businesses, jobs and society in Africa and beyond.' With these words Naledi Pandor opened the symposium 'Science Diplomacy and International Development', which was held in her honour on 27 Februari…

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

Bacteria caught red-handed, deeply frozen just as they were about to cause Lyme’s disease. Ariane Briegel is wildly enthusiastic about the wonders she observes thanks to three elements: a freezing technique, a camera-equipped microscope, and AI. ‘It’s fascinating. Every single cell is different.’

The Leiden | Islam interview series contains short documentary-style videos including interview flashes with leading scholars in the field of Islam and Muslim societies. With this series, LUCIS aims to show the value of unconventional insights related to Islam and Muslim societies, and to relate them…

From 1550 onwards, a great interest in the natural world developed across Europe. This interest was not only stimulated by a growing knowledge of local flora and fauna, but also by the import of numerous exotic animal and plant species. Think, for instance, of researches and collectors like Gessner…

Lecture, Kaiser Lente Lezing

To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his findings are still very interesting for future observations.…

Bringing science, technology and innovation to places that normally do not have access to these areas of knowledge. This is the goal of the first Open Science Hub in Portugal, founded in 2017 in collaboration with Leiden University. The hub is managed by assistant professor of astronomy and society…

An international team led by Leiden astronomers has, after years of searching and defying the boundaries of a telescope, for the first time directly captured polarised light from an exoplanet. From this light they can deduct that a disk of dust and gas orbits the exoplanet. In this disk moons are possibly…

Twee teams of astronomers, including from the universities of Amsterdam and Leiden, have discovered how hot gas giants are surrounded by large halos of thin helium gas, an indication that they are slowly losing their atmosphere. The helium, that was recently seen for the first time by the Hubble space…

How does the government know whether science policy has the desired effect? According to Professor Barend van der Meulen, a variety of evidence about the effectiveness of science policy and proper gathering of this evidence are more important than a strict scientific method. Inaugural lecture 27 Ma…

The eighth issue of the JLGC explores the diverse and interdisciplinary research on our multifaceted relationship with animals which is currently taking place, re-examining the relationship between humans and animals, and the definitions involved.

This is a Special Issue of the peer-reviewed journal 'Social Sciences and Missions', which provides a forum for exploration of the social and political influence of Christian missions worldwide.

The skin has recently gained attention within body studies for its many specific cultural and social associations, in addition to its biology. This project aims to examine the different layers of meaning and the functions invested in the skin in ancient Greece: how did ancient Greek literary and medical…

The Leiden Centre for Theoretical Philosophy (LCTP) is a platform for analytic philosophy in a broad sense at Leiden University. Its members do research in philosophy of science, philosophy of logic and metaphysics, with a keen interest in the history of topics such as mind, knowledge, truth, and ti…

In ancient Greece and Rome, nighttime encompassed a distinctive array of cultural values that went far beyond the inversion of daytime. Night was a mythological figure, a locus of specialized knowledge, a socially significant semantic space in various literary genres, and a setting for unique experi…

Civil service systems are often targets of criticism globally. This article seeks to fill an evidence void about government performance and meritocracy

Welcome to the |0100| blog where our team will be sharing insights from the field and contributing to the various discussions and debates around AI, Islam and scripting futures.

The World Cultural Council (WCC) and Leiden University are pleased to announce that the 34th Award Ceremony will take place on Wednesday 8 November 2017 in Leiden. This year Professor Omar M. Yaghi, the James and Neeltje Tretter Chair Professor of Chemistry, University of California-Berkeley, USA,…

Scientists rarely take ‘paranormal experiences’ seriously. Furthermore, in the recent past the concept of the ‘paranormal’ did not even exist in philosophy. William James, who extensively studied mediumistic phenomena, labelled them ‘wild beasts of the philosophical desert’.

Launched in early March, GlobalSCAPE is an EU-funded project seeking to understand the current state of science communication globally, especially in non-western countries. Through the Department of Science Communication & Society, Leiden University is one of the main partners of the project, which…

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.
