How do you turn your thesis into an academic article? That's a question Floortje Fontein, who conducted research into inclusive leadership, can answer. She looked at how public managers manage a diverse team. She got a 9 for her thesis and is currently working on several articles based on the results…

A Dutch consortium has received €6.7 million to accelerate the development of nanomedicines together with patients. Researchers from Leiden University play a key role in the project.

Does medicine make patients feel better or worse? We are getting better at predicting this from people’s DNA profiles, says Professor Jesse Swen. ‘It never fails to fascinate me how one DNA base pair can have such a huge effect on treatment with medication and the outcome.’

A staggering 6.5 billion chicks are killed worldwide every year. These are generally male chicks that are of no economic value. In Ovo has developed technology that can quickly determine the sex of a chick, to ensure that only female chicks are hatched. The first 150,000 chicks have now hatched in this…

Martina Vijver has been nominated as Teacher of the Year of the Faculty of Science. She gets this nomination for the course Ecotoxicology she taught in 2022. The 52 students who took the course were hugely enthusiastic, as can be read in their positive reviews. What is so great about this course then?…

During a festive meeting, the In-house Emergency Service (IES) team of the Pieter de la Court Building was pampered by the Faculty Board FSW and the UFB management on 10 February 2022. It was high time to thank the team for their service, drive and commitment. Symbol of this gratitude is the statuette…

How do fats and enzymes in the brain contribute to multiple sclerosis? In his PhD research, Daan van der Vliet combined chemistry and neuroscience to gain new insights into how brain disorders develop.

For the Bachelor Honours Class 'Mass Extinction', students produced podcasts about the past, the present and the future of mass extinctions. What exactly is lost when a species goes extinct? What are the practical consequences? But also: does humanity have the moral duty to protect other species?

Leiden ecotoxicologist Martina Vijver helped shake a European policy proposal in a single weekend. Not with a new experiment, but with years of research on pesticides – and an urgent letter that reached Brussels.

What is the best way to restore dune ecosystems? The project TERRA-Dunes researches the role of soil microbes in the development of natural dune areas. Recently, the project went into a new phase: planting 412 oak seedlings grown in different type of soils.

Better pay and new agreements with streaming platforms: the actors’ strike that brought Hollywood to a standstill a few days ago is mainly about money. But there is something else that film actors are worried about: the increasing use of Artificial Intelligence. Is this fear justified?

Eiko Fried has been appointed professor of Mental Health & Data Science. This combined chair neatly fits the view that understanding complex mental health issues require the integration of statistical methods. ‘The idea that mental health problems are monocausal entities with simple etiologies is no…

The Schoof cabinet has presented its budget. As expected, higher education is facing severe cuts. In the coming period, the Executive Board will regularly look at the consequences of what it deems an irresponsible policy.

Once a year, former employee and avid runner Dennis Hoencamp returns to his old workplace. That’s when he competes in the Leiden Science Run. As an event coordinator, he once devised the relay race as an anniversary activity. It grew into an annual event for the entire University and the Bio Science…

The digital age offers unprecedented opportunities: information is always accessible, systems are interconnected, and processes are automated. However, these developments also give rise to new threats. During the Night of Digital Security on 26 May at the Wijnhaven building, more than experts shared…

Within a single generation, the digital world has changed completely: from a technical niche for ‘nerds’ to a reality that affects everyone. Cyberattacks, data breaches and system failures can disrupt essential social processes. How can we ensure that our society remains digitally resilient?

The first full-colour images of the cosmos from ESA's space telescope Euclid were presented today. Never before has a telescope been able to take such crystal-clear astronomical images of such a large part of the sky and so far into the deep universe. The five images illustrate Euclid's full potential;…
