Migration is nothing new. A lot of people immigrated to the United States after it was ‘rediscovered’. The Netherlands also colonised a part of the New World and gave it the name New Netherland. Pepijn Doornenbal, a master’s student History, conducts research in the United States about how different…

We talk with Michiel van Elk, about his research into mapping what effects psychedelics have on the human brain and what this means for the possible clinical application of these drugs. The cognitive psychologist shares his findings with a sober view, bringing critics and fanatics closer together for…

After almost four decades, Leiden and Eindhoven chemists have resolved the discussion about the correct model for the simplest chemical reaction in heterogeneous catalysis, which is essential for fuel cells. Using a unique curved platinum surface, Ludo Juurlink and PhD candidate Richard van Lent from…

How can you see something that’s invisible? Well, with Euclid! This future ESA telescope will map the structure of the Universe and teach us more about invisible dark matter and dark energy. Scientific coordinator of Euclid and Leiden astronomer Henk Hoekstra explains how this works.

The more data from cancer research we pool, the better we can search for new treatments. But how can we keep patient data safe when sharing it? Leiden researchers will tackle this challenge in a major European project.

Six researchers from Leiden University have received an ERC starting grant. This grant of on average 1.5m euros will enable the researchers to launch their own project, form their own research team and develop their best ideas.

Who will win this year’s Teaching Prize in the Faculty of Humanities? Who will the students honour with this coveted token of their appreciation? Read on to get to know four passionate teachers – about minds working at top speed, experimental teaching styles and that satisfying moment when the penny…

Leiden physicists Alexandre Morin and Samadarshi Maity study self-organisation and flocking phenomena. They shed light on flocking, which helps to understand how it is possible that birds in a flock don't collide. With plastic microbeads, they create an experimental setup and they developed a mathematical…

'You’ll know right away when you meet your true love’ or ‘Opposites attract’: Some persistent beliefs exist about love and attraction, but are they true? Researcher Iliana Samara investigates the dynamics of attraction and explains which love myths we can let go of.

Researchers at Leiden University and TU Delft have combined two techniques that are used to measure the structure of biomolecules, creating a method that is ten times more sensitive.

The Dutch universities are conducting a joint campaign to promote open access: free access to academic and scientific publications. Many Leiden researchers support open access. Given that it involves a shift in the financing from the reader to the author, they point out the need for effective agreements…

How can public organisations create societal added value? This theme was in the spotlight at the second Leiden Leadership Lunch, which was held on Friday 28 September. Students, academics and government professionals joined in the discussion.

Astronomers from Leiden Observatory have developed a new method to find distant quasars and better distinguish them from other objects that look like them, using machine learning techniques. The research result has been accepted for publication in the journal Astronomy & Astrophysics. It is the last…

What if particles don’t slow down in a crowd, but move faster? Physicists from Leiden worked together and discovered a new state of matter, where particles pass on energy through collisions and create more movement when packed closely together.

Shell cooperates with theoretical physicists and chemists of Leiden University to research how quantum computer algorithms can help simulate complex molecules.

People in leadership roles are unlikely to discuss leadership skills with their colleagues. But that is precisely what we as a university would like them to do. Because trust in one another’s abilities will make us an agile university that innovates and makes room for talent.

A galaxy is already incredibly large, but it can get even bigger. Astronomer Reinout van Weeren investigates clusters of galaxies, one of the largest structures in the universe. For his research into the origins and evolution of these clusters, he obtained an ERC Starting Grant of 1.5 million euros.…

Restoring a natural plant environment on exhausted agricultural lands and in nature areas is difficult. We can speed this up by steering the soils towards the desired situation. This is what Martijn Bezemer, newly appointed Professor of Ecology of Plant-Microbe-Insect interactions at Leiden University’s…

The radio telescope LOFAR, with a major contribution from Leiden Observatory, has produced the most detailed radio map of the Universe ever made. Never before have so many cosmic radio sources been captured in a single survey: 13.7 million.

How did disability become a global concern? In this project we will identify the contribution of international agencies, governmental and non-governmental organizations and, just as importantly, disabled people themselves, to the IYDP and by showing the connections, interactions and entanglements between…

The US-Israeli strikes on Iran have been welcomed by critics of the regime but have also prompted intense concern. They’ve triggered a dangerous domino effect across the region and beyond. Leiden experts share their insights on the potential consequences.

An MRI scanner is much more than a machine alone. It is an extremely versatile technique that provides numerous opportunities for finding out more about the workings of the human brain, says Thijs van Osch, Professor of Radiology, with a particular emphasis on experimental cerebrovascular imaging. Inaugural…

Leiden has the second-highest percentage of female professors of all the Dutch universities. These are the results of the annual Women Professors Monitor. The Open University is the only university with more female professors.

Plants use sunlight to perform photosynthesis, but with too much light they have to dim their activity and protect their cells against photo damage. The protein PsbS acts as a light-stress sensor and plays a key role in this process. Article in Nature’s Scientific Reports.

Bright explosions appear all over the radio and gravitational-wave sky. This dynamic side of the universe which has just been discovered, can be mapped by self-learning machines. The National Science Agenda granted 5 million euro’s to CORTEX, the Center for Optimal, Real-Time Machine Studies of the…

Will Leiden be the first city to have wall poems in sign language? It will, if sign language researcher Victoria Nyst has her way. She recently started a crowdfunding campaign together with the Leiden Language Museum and the TEGEN-BEELD Foundation.

The Leiden Institute for Brain and Cognition (LIBC) is concentrating increasingly on research into the role of the brain in language development. The institute has now set up the LIBC Language website that brings together all the information on this research.

The Netherlands eScience Center has announced to fund a new Path-Finding Project led by Dr. Dorothea Samtleben from the Leiden Institute of Physics (LION). This project aims to make the processing of detection signals more efficient for the KM3NeT neutrino telescope, which is currently under construction…

Using biologically inspired algorithms on 'edge devices', such as cameras and mobile phones, is what Svetlana Minakova's PhD research was all about. She conducted research on Convolutional Neural Networks(CNN). Making these algorithms work in different situations is a complicated task. 'Most design…

After a three-year absence, Lennart Kruijer has returned to the Faculty of Archaeology. He previously completed his PhD within the VICI project Innovating Objects, and now returns as a postdoctoral researcher in the Anchoring Innovation programme.

‘Voor de formatie moeten grote, controversiële beslissingen worden genomen waar een breed draagvlak voor moet zijn. Dat vraagt om goede afspraken en een rustig proces’, zegt Wim Voermans, hoogleraar Staatsrecht, in een uitzending van WNL op Zondag.

In the hunt for new particles, physicists look at ever higher energy particle collisions, moving the energy frontier. Some particles however are elusive not due to their high energy, but because they rarely interact. This raises a new barrier: the intensity frontier.

From 1 August, Hermen Jan Hupkes has been appointed Professor of Non-Linear Analysis at the Mathematical Institute. 'Initially I don't think that much will change,' Hupkes says. 'My research and supervising future researchers will continue as before.'
