Would you be more likely to take the train for your next work trip, instead of flying, if you automatically got a first-class ticket? For many Leiden University academics, the answer is yes – according to research looking at what motivates academic staff to choose trains over planes.

There are more molecules that could conceivably be candidate drugs than there are stars in the universe. How can we ever efficiently identify those molecules? Professor of AI and Medicinal Chemistry, Gerard van Westen: ‘I’m going to use artificial intelligence as the co-pilot to make an automated search.’…

The new Ehrenfest multi-storey car park at the heart of the Leiden Bio Science Park was opened today by the Vice-Chairman of the Executive Board of Leiden University, Martijn Ridderbos. The car park, an initiative of the University, should improve accessibility and quality of life on the campus.

Individuals suffering from social anxiety disorder (SAD) consistently avoid eye contact. However, in a non-clinical population, gaze avoidance in socially anxious individuals depends on social situations, Jiemiao Chen saw in a series of experiments, for which she used wearable eye-trackers. On 25 April…

In a new FSW Honours College course students from various academic disciplines dive into the world of artificial intelligence (AI). The course, 'Artificial Intelligence: Understand and Create' was designed by Marc Cleiren and Pieter Pierrot to be accessible to all students, regardless of their prior…

‘Let’s get everyone home safely!’ This was the message of an estimated 750 demonstrators as they marched through the centre of Leiden on 18 November.

The history of the LGTBI+ collective, deeply marked by episodes of violence, repression, and discrimination, is also the history of the struggle for social change and the conquest of civil rights, advances without which contemporary Western democracies could not be explained. More recently, the implementation…

Fifteen hundred years ago, the north-west of what we now call China was a jumble of peoples. How did those Indians, Khotanese and Tocharians influence each other and each other's languages? Associate professor Michaël Peyrot has been awarded an ERC grant of almost two million euros to unravel this 'web…

What do climate change and traditional Japanese music have to do with each other? A great deal, university lecturer Andrea Giolai suspects. He has been awarded an NWO grant to study the relationship in more depth.

Leiden researchers Max van Duijn (Leiden Institute of Advanced Computer Science) and Vasilika Kosta (Leiden Law School, Europa Institute) will join The Young Academy (Royal Netherlands Academy of Arts and Sciences) KNAW)).

Bringing your drug candidates to patients is what many academic chemists dream about, but the road to this goal is long and bumpy. Now, Leiden small molecule nizubaglustat is ready for phase 3 clinical trials. This is thanks to a €132 million funding secured by the biotech spin-out Azafaros.

A new position has been created at the Faculty of Humanities. On 1 September, Marian Klamer became the first Director of PhD Programmes at the Graduate School. ‘I want to find the balance.’

To understand how the brain works, it is essential to map it out in detail. This appears to be possible with a microscopy technique in which Leiden physicists excel. This breakthrough could significantly advance the human quest to understand brain functions.

With a healthy dose of logic and creativity, mathematics student Lance Bakker shows how computers can prove complex mathematics. His method proves intricate formulas without calculating every intermediate step. It earned him a nomination for the Leiden Science Young Talent Award 2025.

From lectures by Robbert Dijkgraaf to a telescope on the ocean floor: during his double bachelor’s in Physics and Astronomy, Jelle Oonk discovered that the path to big cosmic answers sometimes runs through the smallest, hardest-to-catch particles—neutrinos.

Speculation about alien life, a new nitrogen map, AI as a thesis supervisor, groundbreaking telescopes and multi-million-euro investments to combat antimicrobial resistance – the diversity of these topics shows that our readers are just as broadly interested as our researchers. Discover the most-read…

Another year has reached its end. And what a year it has been! On December 4th staff and students of the Faculty of Archaeology came together to celebrate and reminisce. The event's central topic was the end of Jan Kolen's term as Dean. Martina Revello Lami moderated the event.

University lecturer Dario Fazzi and postdoctoral researcher Gaetano Di Tommaso set up a virtual collaboration with the United States last year thanks to a VIS grant. And it was a such a success the project will be repeated next year. Fazzi is looking forward to once again offering his students a multicultural…

Showing your face at dinners and parties at court: it was the way to get noticed by the king in William I's time. Joost Welten's latest book reveals how, during the reign of William I, the elite danced around his throne both literally and figuratively.

At the start of the COVID-19 pandemic, researchers from 15 departments at Leiden University Medical Center (LUMC) realised they could do more for patients if they joined forces. This is how the BEAT-COVID group has been able to rapidly gain knowledge about COVID-19, the role of the immune system and…
