Animal experiments are not undertaken lightly; we are working with sentient beings. As scientists, we have great responsibility to handle laboratory animals with care. Read here how we consider and justify this.

How safe do you feel when you’re walking around the streets of Leiden? Do you generally feel safe? Are there any situations when you feel unsafe in the city? These are the kinds of questions that Leiden’s City Criminologist Marianne Franken – from Leiden University – hopes to be able to answer. In collaboration…

There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

This study aims to explore the use of a behavioral-design-based approach in simulating patient flow through EMTs. It provides a dynamic behavioral simulation model to assess the interactions between patients, staff members, and the related dynamic movements/interactions with the health care facility,…

The Administration and Central Services department supports the Executive Board and is responsible for policy and decision-making.

This thesis aims to test in vitro pipelines to rapidly and cost-effectively identify molecular mechanisms that drive adverse outcomes in clinical use.

We use laboratory animals to address research questions, but only when there is no alternative and the question cannot be answered in any other way. Read here why we conduct animals experiments.

What better way to represent women in the present than to ask them? The Museums Matters Class decided to ask Leiden’s Leading Ladies to loan an object which they felt encompassed their time here, from those in their undergraduate to one of the 23 female professors, with many positions in between.

Up to 50% of all children and adolescents growing up worldwide are exposed to at least one form of childhood adversity (CA), which is one of the strongest predictors for later-life psychopathology.

This editorial to RHCPP discusses how COVID-19 can be seen as a 'creeping crisis' according to the authors of its lead article (Boin et al, 2020) and how resilience may depend on the real heroes behind the scenes of response to disaster and adversity.

Leiden University is ending the experiment with the Binding Study Advice in the second year of the bachelor's programme (BSA 2) with immediate effect. Under the terms of BSA 2, students were required to obtain 90 credits within two years, including their first-year diploma.

The aim of current study was to develop a dried inactivated polio vaccine (IPV) formulation with minimal loss during the drying process and improved stability when compared with the conventional liquid IPV.

As an experiment, student Alicia Cai relied solely on AI tools such as ChatGPT and Claude for supervision while writing her thesis. What lessons were learned?

What should we do about litter in the countryside? Can you tell from camera images if someone is guilty? And what does your heart rate really look like? Get answers to these questions and more at the free ‘Wijsneus Festival’ on Friday 16 September at Leidse Hout Park.

Poetry, video editing, musical art: the first installment of the 48 Hour Project, in which students created a piece of art in only two days, has resulted in a wide variety of creativity. For participants, it was a glimmer of light in a rather dark year of lockdowns: “I felt like I was physically there with…

Fantastic plants, dizzying patterns and pulsating sounds: researchers from Leiden are going to study the effects of a simulated psychedelic trip on the mind and body at Lowlands Festival. Why might this be interesting for therapies?

Vanwege de toenemende drukte, chaos en gevaarlijke situaties op fietspaden roepen de vijf grote gemeenten op tot een verbod. Volgens Geerten Boogaard, hoogleraar staats- en bestuursrecht, ligt de oplossing niet in een algeheel verbod. In EenVandaag licht hij de zaak toe.

This conference explores how reading experiences were shaped both by producers and users of vernacular books. By adopting an international and interdisciplinary perspective (combining book history, literary history, art history, religious studies, and history of knowledge) it aims to contribute to the…

ERC StG SAFE and SOUND has the ambition to connect the policy cycle with data generated in robot testing zones to support evidence-based policymaking for robot technologies.
