On 5 May we celebrate freedom, a basic human right that should not be taken for granted. We asked international students and staff what it means to them.

The Royal Holland Society of Sciences and Humanities (KHMW) has appointed four Leiden professors as members. Petra Sijpesteijn, Vanessa Mak, Mariska Kret and Miranda van Eck have recently joined the KHMW.

What does academic freedom mean? And how do we give shape to it in Leiden? The Academic Freedom Core Team considered these questions and presented its final report on 17 June.

Eight scientists from Leiden University have been awarded a grant by the Dutch Research Council (NWO). With this Vidi funding, the researchers can set up an innovative line of research and further expand their own research group over the next five years.

The English taught interdisciplinary minor Violence Studies looks into various facets of interpersonal violence. Is this minor for all Leiden students? These two 'colleagues' are certain of it.

Minerva, which calls itself the oldest student association of the Netherlands, has the reputation of being an impenetrable bastion. A lustrum exhibition shows the turbulent history and points to a diversity of contacts: from close bonds with Leiden ‘coffee ladies’ to the visit of Sir Winston Churchi…

Can humans perceive single photons? What is our place in the universe? How can we make quantum computers more stable? Five researchers from the Faculty of Science have received funding for their research projects within the Dutch Research Agenda (NWA).

A team led by Leiden University in the Netherlands and the National Radio Astronomy Observatory have, for the first time, robustly detected semi-heavy water ice around a young sunlike star. In this ice, some of the ordinary hydrogen atoms have been replaced by deuterium, a heavier variant of hydroge…

Leiden patriot Pieter Vreede fought for greater popular influence. Historian Dirk Alkemade reveals how this pioneer used radical means to shape Dutch democracy.

An international team of astronomers, led by Will Rocha of Leiden Observatory, using the NASA/ESA/CSA James Webb Space Telescope have discovered that the key ingredients for making potentially habitable worlds are present in early-stage protostars, where planets have not yet formed.

Traces of the past remain hidden in rivers, lakes and seas. In his inaugural lecture Martijn Manders will explain why underwater archaeology is important to understanding our history.

How can chimpanzees, so closely related to humans, have almost no sense of rhythm? ‘The best students ever’ and behavioural biologist Michelle Spierings demonstrated that chimps can actually drum and move rhythmically—each following their own unique beat.

A The Hague-based project is aiming to tackle teacher shortage and socioeconomic inequality reflected in primary education – and the objective is to do so while helping schools face the challenges imposed by the Covid-19 pandemic in the Netherlands. Higher education students are joining hands with primary…

From research on stellar winds to sign language: an impressive seven researchers from Leiden University will receive a prestigious Vici grant from the Dutch Research Council (NWO).

They confounded expectations and went to university anyway – as a woman of colour, a working-class student or refugee... Throughout the centuries the university has always welcomed pioneers. Students for whom going to university was not the obvious choice and who did not grow up in an academic environment.…

How are supermassive black holes born? That is the question astronomer Elena Maria Rossi is trying to answer. But how do you investigate something you cannot see?

The Plants & Planets exhibition brings two worlds together in a dazzling mix of science, nature and art. It opens at Old Observatory Leiden and Hortus botanicus on 7 February.

Researchers using NASA’s James Webb Space Telescope may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.

Life returned to something resembling normal after Covid but other crises soon took its place. These great challenges are also being felt at the University and our researchers are working on solutions. The nitrogen crisis, problems with young people’s services and an increasingly urgent climate crisis:…

Ad IJzerman, Emeritus Professor of Pharmacochemistry, was made a Knight of the Order of the Lion of the Netherlands on 26 April. He was presented with the royal honour by Mayor Elbert Roest in the town hall in Bloemendaal.

When you become very good at one thing, that sometimes comes at the expense of something else. Such trade-offs also apply to bacteria. When becoming more resistant to one antibiotic, bacteria can sometimes become more sensitive to another. Linda Aulin, PhD candidate in the pharmacology group of Coen…

ASTRON en de Universiteit Leiden beginnen samen een nieuwe leerstoel over sterrenkunde en AI. Bijzonder hoogleraar Joeri van Leeuwen gaat deze positie vullen.

PhD candidate Julia Wąsala searches for greenhouse gas emissions in satellite data. As a computer scientist, she bridges the gap between computer science and space research. ‘We really can't do this research without collaboration.’

Green spaces boost mental health—especially in busy cities. A new study from Leiden and Stanford University reveals how nature benefits urban well-being and offers low-cost ways to make city life healthier for everyone.

Professor of Modern China Florian Schneider researches what people do with technology and what technology does with people. Social media, for example. And then mainly in China.

Imagine scanning lion dung or a mouse dropping and instantly knowing exactly what and how much the animal has eaten. Thanks to new DNA techniques, this is becoming increasingly feasible. PhD student Kevin Groen tested how effective these techniques are at unraveling the diets of wild animals.
