Can students help make our cities more sustainable and resilient? The Resilient Cities Hub thinks so: during its knowledge café on 16 January, passionate students talked to municipal officials and pitched their master’s research. ‘In this way, the students learn to step out of the academic world and…

Four years of war in Ukraine have transformed the nature of warfare, with drones, digital defence systems and improvised solutions shaping the battlefield. At a recent symposium, Dutch and Ukrainian experts discussed frontline conditions. What lessons do they see for Europe?

Researchers at the Faculty of Science work at the frontiers of knowledge every day, tackling today’s major societal challenges. Their work is recognised through grants, prizes and other awards. We highlight some of these achievements below.

At the end of March, the Voice of the Child conference launched three films on children’s hearings in European family law courts to support judicial training in child-friendly justice. Researchers from Leiden University have developed a training manual to accompany courses in the EU.

What do bats do at night when they’re not hunting? Using tiny GPS trackers, Leiden researchers discovered that pond bats spend a substantial portion of the night resting – often outdoors. This surprising insight could change the way we protect them.

Next week, Sara Perlstein will defend her PhD on risk talk: the everyday conversations we have about risks with people close to us. From eating sushi to climbing or smoking, these informal talks shape how we deal with danger in other ways than official health advice does.

Forty participants celebrated completing the Kingdom Affairs course with their instructors, family and friends on Friday 24 April. What is this new course about, and why should people take it?

Leiden PhD student Xuequan Zhou has designed a new promising molecule that efficiently kills cancer cells, but does not harm healthy tissue. The trick: the drug is only active when irradiated with light. Zhou’s new compound does this extra efficiently by cleverly self-organising into nanoparticles.…

Where should you plant ten trees so that as many city-dwellers as possible can enjoy them? If a smart algorithm knows how people move through the city and where there are already trees, it can calculate the optimal solution. Data scientist Mitra Baratchi makes this possible. Her students are now using…

Leiden University and four other Dutch universities will appoint 51 PhD candidates to conduct solution-oriented research for and with the African continent.

My name is Eliza Steinbock, I’m 38 years old and I was born and raised in Louisville, Kentucky in the United States. I started teaching and researching at Leiden University in 2014. I research and teach gender representation, mostly of transgender people, in media and culture.

Environmental scientist Rutger Hoekstra addressed the General Assembly of the United Nations on 12 April. And that’s quite a big thing to do. How do you get there as a scientist? And, more importantly, what was his message? In eight questions, Rutger explains what he does and why.

Technology holds so much promise – from self-driving cars to enhanced physical performance from smart implants under the skin. But we should not let ourselves be caught off guard. That is the message of Bart Custers, Professor of Law and Data Science in his inaugural lecture on 21 May. ‘We don’t talk…

At work and in love, shame follows us everywhere. Yet it is precisely by embracing your shame that you can free yourself from it. But how do you do that? You can learn in the new theatre lecture Shamelessly Shame-Free by Professor of Organisational Psychology Aukje Nauta.

Exam, paper, exam, paper. A familiar, though sometimes little unexciting, routine for students. That is why Film and Literary students Sietske de Haan and Wouter Dijkman decided to write a blog post for the course Interculturality. Their impressive achievement was rewarded with a publication on science…
